A spring is a mechanical part that USES elasticity to work. The parts made of elastic material are deformed under the action of external force, and restore to original condition after removing external force. Also known as a spring. It is usually made of spring steel. The type of spring is complex and diverse, according to the shape, there are mainly spiral spring, coil spring, plate spring, etc.

Let me show you the main role that a stretch spring plays in our practice. A stretch spring is a coil spring that is subjected to axial tension. When not under load, the stretch spring between the coil and the coil is generally and tight there is no clearance. In our life can be seen everywhere, the following for the umbrella spring to introduce to you:

Umbrella spring is a general term for the tension spring, torsion spring and pressure spring used in umbrellas. Spring is widely used in umbrellas, and different springs play different mechanical roles in umbrellas. Spring accessories are an important part of an umbrella, common are the middle bar support spring, Z-orientation spring, umbrella bracket pressure spring, umbrella spring, automatic open tension spring and so on.

The umbrella spring is mainly made of carbon steel wire. According to the quality of the steel, carbon steel can be divided into ordinary carbon steel (with higher phosphorus and sulfur), high quality carbon steel (with lower phosphorus and sulfur), high quality steel (with lower phosphorus and sulfur), high quality steel (with lower phosphorus and sulfur) and super quality steel. Umbrella spring is generally made of high quality carbon steel wire processing, strong elasticity, relatively stable quality, fatigue resistance is higher than other materials. The main reason is that the price is relatively cheaper.

Function of umbrella spring: the umbrella stand spring mainly supports the umbrella bone and the umbrella stand, and locates the plastic cover and the arch plate, so that the umbrella cloth on the surface will not turn over due to overstretching when the umbrella is propped open, making the whole umbrella stronger in use, and automatically adjusting the umbrella stretching distance.
