Design cordless curtain springs
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...

Pull Bead Roller Blinds and Cordless Roller Blinds
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)....

 Application of power springs in construction protective devices
Application of power springs in construction protective devices

시간:2022-9-14

 With the development of society, buildings and roads are the cornerstone of the development of human society. People will choose to lay waterproof materials during waterproof maintenance, but people face some problems when laying waterproof materials. When laying waterproof materials, people inadvertently trample on the materials because they do not know that the materials have been laid, resulting in uneven laying of materials and economic losses. Therefore, we need to protect the sites under construction and just completed construction when laying. Many of the existing protective devices are large, which is not conducive to people's carrying, and the protective devices can't be seen by people at night, causing people's damage. The laying of water-proof materials is wasted, and the placement of protective devices is unbalanced, causing collapse and damage to people.   The utility model relates to a wet laying waterproof coiled material construction protective device equipped with a power spring, which can solve the above problems. The power spring requires a housing to limit its outside diameter. The spring stores force during the rotation of the power spring relative to the central axis of the spring housing. When the force disappears, the power spring will produce a torque on the central shaft of the spring housing.   The protective device comprises two expansion columns 1, a contraction device 21, a second fixing block 4 and two expansion columns 1, one of which is provided with a contraction device 21. The retracting device 21 is composed of two rotating discs 12, the first fixed column 13 and the power spring 14. The rotating disc 12 is installed in the...

The constant force spring of the industrial door mainly plays a balancing role and reduces the burden on the motor. The force of the spring is equivalent to the force of the industrial door, which is the most ideal configuration state. If the spring force is too large or too small, it will affect the operation of the industrial door. In severe cases, safety accidents may occur and endanger others.        Constant force springs are often used to provide balance to products, so what is balance?        Constant force springs are most useful in applications that require consistent recoil. Ordinary springs behave according to a mathematical equation called Hooke's law. Hooke's law states that the force of a recoil spring in the direction of recoil is equal to the distance the spring is displaced from equilibrium. Simply put, we look at how far the spring is stretched - multiplied by a mathematical constant, the rate of the spring. The recoil direction of the spring is opposite to the stretch direction. ,km        Hooke's Law does not affect constant force springs because their recoil remains constant throughout their range of motion. Their unique design consists of a thin, coiled steel strip that rests when fully coiled. Constant force springs are loaded when they are partially or fully deployed. When released, the spring springs back, pulling the extended ribbon back and rolling up properly. Since the recoil force is mainly obtained closest to the take-up roll, a constant force is maintained. A constant force spring can...

Constant Force Springs

The extension type of Constant Force Spring represents the most basic, yet most versatile, type of constant force spring. It is a pre-stressed flat strip of spring material which is formed into virtually constant radius coils around itself or on a drum. When the strip is extended (deflected) the inherent stress resists the loading force, the same as a common extension spring, but at a nearly constant (zero) rate. A constant torque is obtained when the outer end of the spring is attached to another spool and caused to wind in either the reverse or same direction as it is originally wound. The full rated load of the spring is reached after being deflected to a length equal to 1.25 times its diameter. Thereafter, it maintains a relatively constant force regardless of extension length. The load is basically determined by the thickness and width of the material and the diameter of the coil. Qianye Spring  offers a stock of constant force springs in a variety of life cycle ranges. Each spring is a coil of high-yield Type 301 stainless steel band that exerts a nearly constant binding force to resist unwinding. We can also provide custom constant force springs to your specifications.        Guide to Mounting Constant Force Springs         A Constant Force Spring is usually mounted by first tightly wrapping it on a drum, then attaching the free end to the loading force such as in a counterbalance application. This relationship can also be reversed. 1.The drum diameter should be 10% to 20% larger than its natural inside diameter. 2.One...

시간:2022-9-14

The electric roller shutter has many advantages, such as beautiful and simple appearance, firm and durable structure, etc. the roller shutter is suitable for a variety of places, such as business office buildings, hotels, restaurants, offices and homes (used as gauze curtain), especially for large-area glass curtain walls. When the roller shutter fabric is put down, it can soften the indoor light, avoid the trouble of direct sunlight, and achieve a good sunshade effect. When the roller shutter is raised, its volume is so small that it is not easy to be detected. Have you ever thought about why the roller shutter will automatically rise and fall, and can freeze at any position without running up or down? You may not have an in-depth understanding, because the addition of variable force spring makes the electric roller shutter achieve this effect. The electric roller shutter extends from the longest to the shortest, and the weight of the lower beam changes from light to heavy. Therefore, the elastic force of the variable force spring needs to gradually increase from small to large, reaching the full stroke and gravity balance. So that the curtain can stop and hover at any position. Many variable force springs on the market can not reach the variable force spring whose force is changing at any section, so many electric roller blinds will add some components (deceleration device, damping device, gear device, limit device, etc.) to achieve the effect of perfect lifting, free positioning and free pause. Qianye often contacts with some foreign curtain industries, especially in cordless curtains and roller blinds, which...

Timer is a precise timing device, which uses mechanical clock to drive the switch. Its time positioning is very accurate, and it can achieve such effect. Spring plays a great role in it. The emergence of timers has brought great changes to our lives. At first, we used the hourglass to determine the time. In modern life, timers have been widely used, enabling people to control time more easily, and even have been applied in military aspects such as time bombs and time detonators. The timer mainly includes three parts. The first part is the power component, spring one-way mechanism, can only tighten, not loose. Tightening the spring provides power for the whole system. The second part is the release component. By a series of gear speed, the number of rotation cycles increases when the spring is relaxed. At the end of the gear system, there are grab wheels, grab claws and swimming wires to ensure that the gear system rotates at a constant speed driven by the spring. There is a device on the swimmer to adjust the length of the swimmer to adjust the swing frequency of the grab claw to ensure that the gear rotates at the set speed, and the tightened spring won 't be loosened at once, nor is it affected by the spring tightness resulting in changes in speed. The third part is timing trigger device, so that a gear in the gear group turns to a certain angle to send a mechanical signal, control interruption. When the timer is screwed to a certain...
