There are many types of curtains on the market today, such as Venetian blinds, Roman blinds and honeycomb blinds. When the curtains are lowered, the windows can be shaded to reduce light entering the house and improve privacy. Generally speaking, curtains are provided with control ropes, which can drive the bottom rail of the curtain to rise or fall. In particular, the bottom rail is raised by a roller take-up hanger, and the hanger can be extended from the roller so that the bottom rail can be lowered.        However, the problem that the control cord may restrain children has been noted, so a cordless curtain has been developed. This cordless curtain can raise and lower the bottom rail by means of a coil spring box. Coil spring boxes used in window blinds usually consist of multiple springs that provide torsion to maintain the bottom rail at the desired height. However, the assembly of such a coil spring...

The roller blinds are blackout roller blinds, soft yarn roller blinds, and Shangri-La roller blinds in appearance. They are mainly corded and cordless. Roller shutters have many advantages such as beautiful and simple appearance, firm and durable structure, etc. Roller shutters are suitable for various places, especially for large-area glass curtain walls. When the roller blind fabric is put down, it can soften the indoor light, avoid the trouble of direct sunlight, and achieve a good shading effect. When the roller blind is raised, its volume is very small, so that it is not easy to be detected.        The bead roller blinds use the rope or chain to ascend and descend. The biggest problem of the rope/bead system is that the curtain will not be pulled when it is too big, and the rope will easily break. It is not very convenient to use, and the rope is easy to get dirty. It is very dangerous for...
Variable force spring in drug delivery device
Variable force spring in drug delivery device
Devices for automatically delivering drugs, such as automatic syringes, are known as convenient and safe means of protection for patients to manage different drugs themselves. For safety reasons, many devices for delivering drugs include covers and other devices that protect users before and after use, such as injection needles. Different devices for transporting drugs are different in their overall design settings. They all have a mechanism for automatically transferring the contents of pre filled and pre filled containers, and there is no need to manually force the contents of the containers into the patient through the transmission components, namely needles and nozzles. Automatic delivery mechanisms in devices used to deliver drugs usually include compression coil springs. The challenge in the design of such springs is to balance the need for sufficient force at the end of the stroke and the need for less force during storage that will overload other parts of the device (when the spring is fully compressed)....

 How long can the spring last?
How long can the spring last?

Tid: 2022-9-14

How long can stainless steel springs last? This is a common problem. You might think that as long as it's not stretched beyond the point of recovery, the spring will always return to its original shape. A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external force, and return to their original shape after the external force is removed. Also known as "spring". Generally made of spring steel, the types of springs are complex and diverse. However, spring life depends on many factors.         1. Spring design Are they properly designed for their intended purpose? Many are not, errors in spring design are the main cause of premature spring failure. When choosing a spring, remember to pay attention to what it is for and how it will be used. Is spring strength more important or elasticity? If you're not sure, experts can help guide your decision.       2. Quality of manufacturing materials       The life of the spring is also related to the quality and modulus of elasticity of the materials used in its manufacture. Make sure your springs are made of the best quality material for the desired application. For example, stainless steel springs have high strength, low stress relaxation, corrosion resistance and heat resistance. However, their performance decreases at sub-zero temperatures.       3. Application pressure and environmental conditions       If the force applied is greater than the spring is designed to withstand, fracture may occur....

 One of the most unique spring designs is called a twin spring.  Its name is derived from the characteristic of having two springs formed from the same strip of stainless steel material.  These custom springs are intended to work together, in unison, doubling the force of a single spring.  Twin springs are a version of a constant force spring, providing constant force throughout the travel length.     The area between the two coils is referred to as the saddle area, which is formed to fit over the part or component that is being pushed.  The saddle can also be cut-out to provide access to the component and is best designed when assigned a dimension to fit over that specific part.  It can be located at different heights between the coils for ease of assembly or as an indicator for direction.     Twin springs are used in a wide range of applications where available space is limited and a relatively strong force is required.  Medical devices and surgical mechanisms incorporate this design to push or feed surgical staples in disposable skin staplers.  Electric motors utilize the twin spring to provide a constant force on the carbon brush, extending the life of the motor and increasing reliability and overall quality. These springs are also referred to as motor brush springs.     Advantages of twin spring:     1. Under the same elasticity, the double winding spring saves volume.     2. Because the shape is symmetrical, the output is more stable.     3. Increase the length of available carbon brushes.  ...

 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. Constant force spring has the characteristic of maintaining constant force in long stroke, and can be applied to products requiring linear movement such as round-trip, sliding, stretching, homing, balancing or labor-saving. For example, we go to the common fan lifting, store display shelves, tape measure, lifting doors and windows and computer monitor lifting. So if you choose a constant force spring suitable for your product, the design has the following 8 steps. 1. Material selection - most flat steel springs produced by Qianye precision are made of type 301 stainless steel. This material is the most readily available and predictable. Thousands of industry engineers can assist in selecting standard sizes to speed up the process. 2. Estimated life cycle - the life of constant force spring is very predictable, making it one of the most important considerations. Being realistic is important because it is estimated that a longer life cycle will lead to larger and more expensive designs. Underestimating the life cycle of constant force springs may lead to premature failure. Common life cycles range from 4000 to about 25000 life cycles. If a longer life cycle is required, the tolerance of increasing spring diameter and force due to low stress levels and small differences in materials...

       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...

As more and more people spend more and more time using computers, computer users spend more time sitting or standing at their desks or workstations in front of devices. Keeping what experts call "the best ergonomic positioning" can improve energy levels and overall comfort. For this purpose, the input and output devices must be placed in appropriate positions. The proper position can reduce the muscle strain of the user's arm and effectively prevent various musculoskeletal diseases, including carpal tunnel syndrome, neck pain, and upper and lower back pain.   The attachment bracket can be used to facilitate the support and position adjustment of the fixed attachment. The attachment retainer allows simple three-dimensional adjustment of two such devices to place the devices in a more ergonomic relative position to meet the needs of various users and workspaces, and has a balancing mechanism for balancing the weight of fixed attachments.   The balance mechanism provided by the wall mounted accessories is superior to the traditional lifting system, because the balance mechanism allows the bracket to move a larger vertical distance for vertical position adjustment. The constant force spring is used to balance the weight of the accessory, screw balance, pulley balance or other low friction devices installed on the accessory retainer by engaging with the roller assembly. The roller assembly can be raised or lowered by the user along the track with minimum force. The weight of the mounting accessories supported by the roller assembly is basically balanced by the balance mechanism. When the user moves the roller assembly vertically up or down, the constant force spring is wound or unfolded...
