 A support device for assisting a patient is used to assist the movement of a patient at the patient support device. In the prior art, a caregiver would operate a patient lift or motor by guiding the lift to raise or lower the patient at the patient support. Such manipulations often require the precise manipulation of heavy forceps and motors by a paramedic to help the patient move around the patient support.        The support means may incorporate a constant force spring design, the support structure comprising a base and an upper portion extending upwardly from the base. The constant force spring assembly may include a carrier slidably coupled to the base secured to a first end of the carrier. The base may include channels that guide sliding movement of the carrier relative to the base of the support structure. The constant force spring assembly may also include a spool and a motor configured to drive the spool. The auxiliary belt may be secured to the spool so that the auxiliary belt is wound and unwound from the spool in response to a motor driving the spool. And the motor can be fixed to the carrier to move with the carrier.        Constant force springs get their name because their motion force is constantly applied. The load is determined by the width and thickness of the material and the diameter of the coil. The tightly wound rollers work in a linear motion, not obeying Hooke's law (F=kX), but constantly generating forces as they deflect.These springs provide...

Torsion springs: where are they used and why did you choose to utilize them?

Time:2022-12-1

There are many types of springs, but the most common are torsion springs. The design of torsion springs is optimized to maintain maximum rotational pressure between two surfaces, these helical or helical springs are usually adhered to the coils at both suspended ends. These ends are connected to external components, which are then rotated to apply bending stress. Unlike other springs, torsion springs are ideally balanced and able to withstand twisting, giving them a place in many industries. Made of various coated metals such as stainless steel, carbon, titanium, nickel or copper alloys, torsion springs are usually wound around a shaft to further increase its stability. The basic principle of a torsion spring is to retain energy as the spring assembly twists. When this is applied, torque is applied in the opposite direction to the deformation angle. This allows energy to be stored and released when necessary, and the torsion spring also secures the mechanism when necessary.       Torsion springs are used in many applications; especially those using pop-up styles. They are used in various clamps and specific door mechanisms such as those found in CD players. One of the most obvious uses of torsion springs is undoubtedly in a mousetrap, which relies entirely on a centrally located torsion spring. They also sit in the center of traditional clothing clips. They are also used in heavier cases such as garage door balancers or car trunk opening mechanisms. Even in ancient times, primitive torsion springs were used as part of the giant catapults (or trebuchets) that were later used...

Spring has been very common in people's daily production and life, ranging from planes, trains and cars to household appliances and daily necessities, and even children's stationery for school. It can be seen how important spring is to our life.     What is the definition of spring? It is a mechanical part that uses elasticity to work. Generally made of spring steel. It is used to control the movement of mechanical parts, mitigate impact or vibration, store and measure the size of force. It is widely used in machines and instruments.     For a professional spring manufacturer, the most basic production goal is to infinitely pursue the high quality of products. Therefore, in order to improve the performance of the spring, it is often assisted by pre heat treatment, that is, the process of strengthening the quality of spring steel is used to further strengthen the spring.     In fact, the so-called pre heat treatment is what we often call annealing. It is to heat the steel to a certain temperature and keep it warm for a period of time, and then cool it slowly. Annealing of steel is a heat treatment method in which the steel is heated to the degree of phase transformation or partial phase transformation, and then cooled slowly after heat preservation. The purpose is to eliminate the structural defects of the spring, improve the structure, homogenize the composition and refine the grain, improve the mechanical properties of the steel and reduce the residual stress; At the same time, it can also reduce the hardness,...

Application of power spring in draw-wire encoder

Тиме:2022-9-14

A draw-wire encoder, also known as a string potentiometer, pull wire position sensor, cable extension displacement sensor, or yo-yo potentiometer. It is a cable driven position or displacement sensor for linear position measurement and velocity using a flexible cable (wire) and a spring loaded spool.   The string pot or cable extension sensor is composed of four main components in the shell: 1. High strength stainless steel cable (rope or steel wire rope); 2. Equal diameter spool (drum); 3. Power spring with high torque and long service life; 4. Rotary potential precision sensor.   In the shell of the sensor, a soft high-strength stainless steel cable is tightly wound on a precision machined cylindrical drum (or spool) with constant diameter, which rotates with the winding and unfolding of the measuring cable. In order to maintain the tension and retraction of the steel wire, the spring is connected to the drum. Then connect the spool to the shaft of the rotary potential precision sensor (or encoder). When the sensor string extends linearly with the moving object, it will cause the roller and sensor shaft to rotate.   For displacement or position measurement, the main body of the sensor is installed on the fixed surface, and the end of the flexible cable is connected to the moving object. When the object changes its position, the cable unfolds and reels and the rotating spool drive the shaft of the sensing device, generating an electrical signal proportional to the linear extension or displacement of the cable. For speed measurement, a tachometer is required. The power spring is mainly used in the equipment of...

       Springs are an important part of many different industries, including the aerospace industry. They form the backbone of many components and allow planes, drones, satellites, solar panels, aircraft controls, valves, throttles, and more to function their way. Without the spring, the industry would not be the same. Strict military and aviation guidelines mean that all components of the aircraft, including the springs, must be of the highest quality and precision; they support a wide range of applications and reduce part weight while maintaining the highest performance standards. This makes springs vital to the aerospace industry. Without springs, we wouldn't be able to have the essentials of aerospace. For example, retractable tray tables, trunk doors, handrails, stairs and cup holders require springs to function. They help open and close many components that wouldn't exist without them—and, more importantly, springs are some of the main elements of aircraft landing systems. They are also present in satellite dishes and probes that allow navigation and are critical for ground service teams that need to refuel aircraft. You can find springs basically anywhere in the industry, and their absence means that airplanes as we know them don't exist. Part of the reason springs are so important in aerospace is that they are very resistant to compression. Aircraft require robust and durable components that do not require frequent maintenance, upgrades or replacements, but are at the same time extremely precise. Many applications in aerospace require the ability to withstand harsh environments on a regular basis, from aircraft that fly around the world every...

Constant Force Springs Design Guide

Тиме:2022-9-14

There are many mechanical components to choose from for your device or application. If your device requires a spring, consider constant force springs. These are a type of extension spring. They do not obey Hooke’s law, so their force remains constant, even when deflected. Because of their flat force curve, constant force springs are suitable for applications that require a smooth range of motion and a constant load. Learn more about this type of spring to see if it could work in your device or application. Constant Force Spring Benefits There are many benefits of constant force springs that make them suitable for a number of applications: Have small space requirements Provide a smooth range of motion Have no inertia to overcome Mount to existing hardware Produce a counterbalance effect For these reasons, constant force springs are versatile enough to work for a number of applications in which a constant load is required to counterbalance, tension, retract or dispense. This is why they’re frequently used to enhance surgical devices, deploy and retract doors on aircrafts, and counterbalance windows.   Design Considerations If you decide that constant force springs are ideal for your application, here are some considerations to think about in the design phase of your project. Load Conditions Constant force springs produce a force as the material is extended. Constant force springs are rated at a maximum operating length. This means that the maximum travel must be lower than the difference between the spring’s unextended length and maximum safe operating length. Material Another important design consideration is material. 301 stainless steel is commonly used for standard-issue...

Add constant force spring in the mechanical arm to make it more stable

Тиме:2022-9-14

Adjustable mechanical arms are commonly used in offices, laboratories, studios and other locations to support objects at various angles and heights, such as lights, computer screens, laboratory instruments, microphones, etc.   The adjustable manipulator consists of a base member and two connecting rods connected through a pivot joint, which are held in place by friction in the joint. By using spring assisted balancing devices that compensate for most of the weight, the amount of friction required to keep the equipment in place is reduced.   The pivot is a connecting ring that can rotate around an axis set at the pivot point, and a way to attach a spring to the pivot point to reduce the amount of force required. Apply to the arm to place the supported object in the desired position. The auxiliary balance device uses a constant force spring, because the constant force spring provides a smooth range of motion and a constant load in the extension or retraction direction. This can provide smooth motion and force requirements that predict the smallest detail, and the force applied by the constant force spring is more constant over the entire range of motion of the two arms of the device. If coil spring balance is used, a constant force may not be applied to the supported object at all positions of the upper arm part and the lower arm part. For example, at the far end of the range of motion, usually, the force applied to the supported object is insufficient or too large, making it difficult and troublesome to place the...

Scene principle of constant force spring

Тиме:2022-9-14

The constant force spring is made of stainless steel strip. The high-strength steel strip is shaped by specific spring production equipment. When it is straightened by external force, the spring will naturally roll back and produce elastic force. However, when our goal is achieved, it can return to the starting point specified by us after displacement. So do you know that constant force springs can be applied to those scenes? Let's have a look!      Constant force spring has the characteristic of maintaining constant force in long stroke. In a very small device space, it can achieve very high elastic output. It can be applied to the nail pushing device of nailing gun for linear pushing. When the fixed force spring is straightened by external force, the spring will naturally retract and produce elastic force. It has the movement functions of balancing or saving force. It can be applied to the height adjustment of computer display and electric fan.      The fixed force spring can achieve extremely high elastic output in a very small device space. Its function can be applied to product applications requiring linear movement such as round-trip, sliding, stretching, homing, balancing or labor-saving, such as automobile cup holder.  Shenzhen Qianye Precision Metal Co., Ltd. was established in 2006 to supply high-quality stainless steel springs for many fields. Through continuous efforts, 19 patent certificates and 4 spring equipment software copyrights have been granted by the State Intellectual Property Office, and an enviable industry influence has been built. The company designs and manufactures a wide range of power springs, constant...
