Physical principle behind constant force spring: When you walk into your office building on your way to work every day, or into your local bank, or any commercial facility, you may open a heavy glass door. When you cross the threshold, the door closes behind you, and you don't think about it. However, the heavy glass door was probably closed by a constant force spring. Constant force springs are widely used in daily applications. From door closers to rope and hose retractors, to sports equipment, toys, motors, etc., constant force springs exert force at an amazing high frequency and consistency. Let's take a closer look at the basic physics behind the constant force spring. In the 17th century, the British physicist Robert Hooke proposed a formula for force and elasticity, which is now called Hooke's law. Hooke's law states that the force (f) required to stretch or compress a spring for a distance (x) varies linearly in proportion to that distance. The formula is f=kx, where k is a...

Design of constant force springs: A constant force spring is a spring that exerts a constant force over its range of motion. That is, it does not obey Hooke's law. Typically, a constant force spring is constructed as a coiled band of spring steel so that the spring relaxes when fully coiled. When it is unrolled, the restoring force comes mainly from the portion of the belt that is close to the roll. Since the geometry of this region remains nearly constant as the spring unfolds, the resultant force is nearly constant. By creating a spring with a variable pitch, you can make a push-shape spring with a constant velocity. Placing a larger pitch in a larger outer diameter coil and a smaller pitch in a smaller outer diameter coil will force the single spring to fold all coils at the same rate when compressed. Design of Constant Force Springs: A constant force spring is a coil of prestressed...

Traditional power springs and preloaded springs: Traditional power springs and preloaded power springs are fabricated from spring steel bars to provide torque. Spring steel is a low alloy, medium carbon steel or high carbon steel with a very high yield strength. Objects made of spring steel can return to their original shape despite significant bending or twisting. Power springs use flat (unstressed) steel windings, while pre-stressed power springs use pre-stressed steel to produce a larger range of usable torque than conventional power springs. During the manufacturing process, the spring is wound into the retaining ring or the customer's housing (the retaining ring is pictured below). When ready for final installation, carefully install the spring into its housing with the outer end attached to the outer edge and the inner end attached to the mandrel (see photo below). During operation, the housing or mandrel will be fixed while the other component is free to rotate. Depending on the requirements of your specific design,...

Constant force spring is used in removing an implanted object using laser cut hypotubes: Removal or extraction of the lead may be difficult. As mentioned above, the body's natural healing process forms scar tissue over and along the lead, and possibly at its tip, thereby encasing at least a portion of the lead and fastening it even more securely in the patient's body. In addition, the lead and/or tissue may become attached to the vasculature wall. Both results may, therefore, increase the difficulty of removing the leads from the patient's vasculature. A device for removing an implanted object from a body vessel, may comprise a sheath assembly comprising an outer sheath assembly and an inner sheath assembly, and a pin, the outer sheath assembly comprising an outer sheath and an outer band, the outer band coupled to the pin, the inner sheath assembly comprising an inner sheath and a tip, wherein the tip has a cutting surface, the inner sheath comprising a proximal end and a distal end, wherein the distal end of the...

Qianye constant force spring application principle: Constant force spring is made by winding the steel strip into a coil. The stress added to the spring determines its diameter, strength, and life. The action of a constant force spring is very similar to the action of stretching a ribbon. Spring stretching and rewinding, the part of the work with the spring itself circle formed tangent, as long as the diameter of the spring is certain, the force of the spring is constant. In extremely long spring designs, varying diameters have an advantage, and the tension increases slightly as the spring is stretched. However, this increase is small relative to the length of the stretch and can be ignored in many applications.Constant force spring is made by winding the steel strip into a coil.

Power springs in hose reels: Transmission hoses and wires are necessary for automotive production and maintenance work, but they are time-consuming and labor-intensive to sort out after use. Another common problem is safety when handling them. This can cause serious injury if the operator is inexperienced. Bulky and unwieldy hoses are also an added risk, especially if they are too short for the job. This forces the operator to move into dangerous positions that can cause injury. The hose reel now solves these problems by incorporating the maneuverability of the power spring, allowing the long hose to automatically retract after use and align itself continuously and neatly when retracted. In addition, considering the limitations of floor layout and staffing, the hose reel with the addition of the scrolling bar can make full use of space and improve the workplace environment. After use, the hose or wire is retracted to the winder for storage, and generally will not break, and low friction, which can extend the service life of the hose or wire. The tension on the power spring is pre-loaded at the factory, and springs produced by improperly selected manufacturers may become untensioned or over-tensioned. Too much tension can lead to fast and violent retraction as well as a short life span, and the elasticity can fail quickly. Therefore, it is recommended that manufacturers of hose reels look for high-quality spring manufacturers, because the current reel winding function of the emergence of a deep expansion of the advertising market, so that more electrical products are constantly in the upgrade to create new product selling points. Choosing the right...

Power spring solves the problem of insulin syringe: Mention of diabetes, I think everyone is not strange. Data show that by the end of 2021, the total number of type 2 diabetes in China was about 120 million. When oral hypoglycemic agents are standardized and blood glucose control is still unsatisfactory, insulin injection is an inevitable choice for the treatment of type 2 diabetes. Many may not know that insulin injections require dedicated syringes. Some kids are worried. Does injection take technical issues into account ? Actually don 't worry at all, because what, because the use of the Qianye power spring ! Qianye power spring can provide small and highly accurate drug dose. The quantitative drug is injected into the body through the spring fixed force, thrust and homing speed. The thrust distribution of the steel strip spring accurately matches the sliding force of the traditional syringe.

The spring in the timer: 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...

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

Qianye 정밀 무선 블라인드 스프링: Imagine, on the weekend of a busy work week, unloading from work, taking a hot bath, having a leisurely dinner, and when it's time to rest, draw the curtains to isolate the noisy world outside, and then, beautiful and beautiful Sleeping until you wake up naturally, this is not the most important thing for every office worker. However, for families with children, curtains have increasingly become a new safety hazard, especially for families with roller shutters. The pull rope of the roller blind is usually closed at the bottom or the side. If it is not fixed, the rope will slide down to form a loop, which is easy to wrap around the neck of the child, causing the child to suffocate, and even lead to death in severe cases. It is reported that there are many cases of suffocation and death of children due to rope entanglement accidents every year, mostly children under the age of 4. The federal health minister has said that it is best to replace all corded curtains with cordless curtains in homes where children live or visit, especially in children's bedrooms and play areas. Curtain cords trap airways everywhere, even in cribs or bedrooms that many parents think are the safest.
