Helical extension spring with endurance strength

Abstract

The invention discloses a helical extension spring with endurance strength. The helical extension spring comprises a first helical coil spring, a second helical coil spring, a rigid connecting rod, an anti-shake balance member, a first hook and a second hook. One end of the first helical coil spring is connected with one end of the second helical coil spring through the rigid connecting rod; the anti-shake balance member is arranged on the rigid connecting rod; the first hook is connected to the other end of the first helical coil spring, and the second hook is connected to the other end of the second helical coil spring. The helical extension spring has good stability and endurance and can be used for bearing high load and attenuating vibration.

Description

technical field [0001] The invention relates to the field of springs, in particular to a helical tension spring with long-lasting strength. Background technique [0002] There are many types of springs. According to the nature of the load they bear, springs are mainly divided into four types: tension springs, compression springs, torsion springs, and bending springs. According to the shape of the spring, it can be divided into coil spring, disc spring, ring spring, leaf spring, coil spring and so on. Coil springs are made of spring wire, and are the most widely used because of their simple manufacture, low price, and easy detection and installation. The spring can be made into a compression spring subjected to a compressive load, a tension spring subjected to a tensile load, or a torsion spring subjected to torque or torsional motion. [0003] However, the helical tension springs currently used have poor stability and poor strength and durability, and cannot be used for be...
