 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...

Application of spring in display

Час: 2022-9-14

The diversification of modern life, people in the pursuit of high quality life at the same time also constantly in innovation. Leisure, shopping traditional products only meet material needs, people began to pursue diversified products. Let me feel deeper, such as display lifting design, this design to work and life has brought a lot of convenience. The reason why the display can rise and fall is the internal use of constant force spring free lifting principle, designed to adjust the display height of the elevator. With the help of the spring tension, the height can be freely adjusted. Compared with the traditional manual adjustment, the spring is simpler to use and more convenient to operate. The constant force spring is made of stainless steel strip. The high-strength steel strip is shaped by a specific production spring equipment. When the external force straightens it, the hair will naturally roll back and generate elasticity. However, to achieve our goal, we can return to the starting point after displacement. The advantages of the Qianye constant force spring over the traditional wire spring are: 1. In a very small installation space, a very high elastic output can be achieved. 2. A constant spring force is maintained throughout all strokes. 3. The pre-force stroke is short, and only a short stroke is needed to achieve the required elastic force. 4. The original length is smaller than the wire spring, and the stroke is unlimited. In general company venues, a large amount of information and materials need to be processed in the meeting, and different people...

Constant force spring, also known as hair spring, is made of stainless steel strip. The force added to the spring determines the diameter, force and life of the spring. The action of constant force spring is similar to that of stretching ribbon. The spring stretches and rolls back, and the working part is tangent to the spring ' s own circle. As long as the diameter of the spring is certain, the force of the spring is constant. According to the application principle of constant force spring, constant force spring can be divided into linear constant force spring and rotational constant torque spring. When linear stretching force units are : kg, Newton, pounds, etc.     Then how long can the constant force bar be used ? The life of the constant force bar is limited, and the life requirement of the spring should be considered when designing the constant force bar. This step is important because it affects the things behind the design ; improper consideration may lead the design to a wrong direction ; properly considered, the design will be easier to succeed. It is very important to determine the number of spring stretching before designing the constant force bar. Spring stretching times explanation : a refers to the spring in any part of a stretch and roll back process. Since the constant force spring provides force through the bending of the spring, any part used belongs to the spring body. In other words, a spring with a total design length of 25 ’ uses the length of...

Силови пружини, използвани в системите за стартиране с откат

Час: 2022-9-14

 Small engines are well known and are commonly used in lawn mowers and garden tractors and various other garden and lawn maintenance tools, in addition to other environments. Typically, each of these engines is equipped with a recoil starting system that includes a rope that rotates the starting mechanism to engage a flywheel that is connected to the engine for starting purposes. Once the rope starter is pulled, the recoil mechanism is always provided with the engine to reel the starter rope back to the starting mechanism.   The recoil portion of the starter mechanism is operated by a power spring that tensions when the operator pulls on the starter rope. Once the rope is fully pulled, the operator releases it. Most power springs on the market often fail, so the recoil rewinding mechanism needs to be disassembled and the spring replaced. And replacing the spring is a tedious task because the operator needs to keep the spring in the cavity inside the recoil starter pulley and then coil the spring into the pulley mechanism while keeping the spring in the coiled position and under sufficient tension. Such a procedure requires not only skill, but sometimes infinite patience. That's why the quality of the power spring is a top priority - after all, no one wants to change the power spring inside too often.   Shenzhen Qianye Precision Metal Co., Ltd. was established in 2006 to supply high-quality stainless steel springs for many fields. Through continuous efforts, 20 patent certificates and 4 spring equipment software copyrights have been granted by the State Intellectual Property Office, and an enviable...

Advantages of Qianye power spring in electrical take-up

Час: 2022-9-14

As we all know, take-up spring can help take-up. It is used in many electrical products, and hair dryer is no exception. However, all such household appliances have a common feature, that is, they need a wire group to connect the power supply. However, this power line will bring some trouble to our sorting. The function of winding up lies in this. It can bring a free shrinkage process to the electrical wire group and make its winding up easy and practical. In fact, although the process of electrical wiring is not a high-end principle, it is better than cleverness. Its working principle is not complicated. It uses the spring box to limit the outer diameter, so that the center of the spring is connected with the power shaft. When the line is pulled out, it can make the shaft and the spring rotate relatively, and the spring will roll on the power shaft and store the corresponding kinetic energy. When the external force disappears, the spring will generate torque to drive the power shaft, so that the line can be retracted back into the box. In the take-up function of the reel, the effect of the power spring can not be underestimated. It can often help the required goods to take up the line quickly and simply, and become an auxiliary software favored by people. It is also due to the spring to store kinetic energy. It uses the characteristics made by the spring bearing force, and effectively uses its mechanical energy storage and driving force output, so that...
