Description

Technical Field

[0001] The utility model relates to the technical field of special-shaped springs, in particular to a special-shaped spring which is not easily deformed. Background Art

[0002] Compared with conventional springs, the outer wall of the special-shaped spring is irregular in shape. According to the production of special structures and the spring structure required under many bending conditions, they can be solved by special-shaped springs. After passing through too many curved corners, it may be disturbed by bumps and various external objects when returning to its original shape, causing the spring side wall to be stuck in half and unable to be retracted. If this state is maintained for a long time, it will not be able to assist in contraction in the later stage, which will cause the side wall of the spring to deform and the elastic effect will be weakened.

[0003] The Chinese utility model patent application publication specification CN215487362U discloses a non-deformable special-shaped spring, comprising a support cotton, a blocking rod is arranged at the side wall of the support cotton, a clamping mechanism is connected through the outer side wall of the support cotton, and the inside of the clamping mechanism includes a movable column, a special-shaped wire is connected through the inner side wall of the movable column near the support cotton, a U-shaped rod is connected through the middle of the inner side wall of the special-shaped wire, and a triangular block is connected through the middle of the side wall of the U-shaped rod. The U-shaped rod is pressed against the side wall of the triangular block through the outer side wall, and because the side wall of the triangular block is triangular, it can rotate toward the outer circle and lie on the inner side wall of the movable column. When the bending force on the upper and lower ends of the elastic spring disappears, the upper and lower side walls of the elastic spring become shorter, and its width increases. When it slides along the side wall of the movable column to the outer end and approaches a parallel state, it is blocked by the side wall of the movable bead and is restricted thereto, which is conducive to the automatic recovery of the elastic force at the side wall of the elastic spring.

[0004] However, the device lacks the function of a telescopic rod. When in use, when the spring is used for shock absorption for a long time, the uneven force on the spring will cause the spring to deform, causing many troubles, so as to affect the shock absorption and contraction effect of the entire spring. Not only that, the device also lacks the function of limiting the spring. When in use, the spring will tilt left and right when compressed and extended, causing many troubles, so that long-term use will cause the spring to deform left and right. Utility Model Content

[0005] The purpose of the utility model is to provide a special-shaped spring which is not easy to deform, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0016] 1. This is a special-shaped spring that is not easy to deform. Through the arrangement of the telescopic rod tube, the telescopic rod and the spring, when the spring is stretched or contracted, the telescopic rod also moves inside the telescopic rod tube.
