Description

Technical Field

[0001] The utility model relates to the technical field of springs, in particular to a multi-directional tension spring. Background Art

[0002] A spring is a mechanical component that utilizes elasticity to function. Parts made of elastic materials deform under external forces and return to their original shape when the force is removed. Springs are typically made of spring steel. Their elasticity can be used to control the movement of mechanical parts, mitigate shock or vibration, store energy, and measure force. They are widely used in machinery and instruments.

[0003] After searching, the utility model patent with Chinese patent publication number CN201310591Y discloses a tension spring, comprising a deformable body, and a hook extending outward at each end of the deformable body, wherein the deformable body is spiral and has multiple spiral coils, and when the spring is not axially stretched, the multiple spiral coils are tightly packed without gaps; the device installs and fixes its tension spring body by hooks on both sides, but in actual use, when the stretching direction of the two sides of the tension spring moves, it is inconvenient to firmly fix it by relying on a single hook, and after the tension spring is fixed by screws or welding, the stretching direction of the tension spring is fixed, which will cause the stretching of the spring body to be distorted during the stretching process, thereby damaging the tension spring and causing it to lose its rebound effect. For this reason, a multi-directional tension spring is proposed. Utility Model Content

After the support plate is installed to the corresponding position, when the equipment moves to change the stretching direction of its tension spring body 2, the arc moving block 12 is driven by the arc plate to move inside the moving groove, and the arc moving block 12 moves inside the arc limiting groove through the limiting slider 13, thereby realizing the free direction movement of the tension spring body 2, and completing the change of the tensioning direction of the tension spring without causing damage to the tension spring body 2.
