Problems solved by technology

However, in some workplaces, it is necessary to use the coil spring to realize the function of the leaf spring, and when the coil spring bends to one side and the other side, it needs to form different bending degrees, which is mostly difficult to achieve for coil springs

Embodiment Construction

[0016] Examples, see figure 1 with figure 2 Shown: Variation helical spring, including spring body. The spring body has a lower side 11 and an upper side 12 . The so-called lower side 11 and upper side 12 refer to the horizontal placement of the coil spring from left to right, the lower part of the spring body is defined as the lower side 11 , and the upper part of the spring body is defined as the upper side 12 .

[0017] Further speaking, the lower connecting sleeve 21 covers the lower side 11 . The left side of the lower connecting sleeve 21 is provided with a spherical left recess 221 opening to the left, and the right side is provided with a spherical right recess 222 opening to the right. Between the adjacent left pit 221 and the right pit 222, a rigid connecting rod 23 is connected. Right sphere 232. In this way, the distance between the adjacent lower sides 11 is defined by the rigid link 23 , so that the variation coil spring has a greater degree of curvature wh...

Abstract

The invention discloses a different-change spiral spring. The different-change spiral spring comprises a spring body, the spring body is provided with a lower side edge and an upper side edge, the lower side edge is sleeved with lower connecting sleeves, left spherical pits open leftwards are formed in the left sides of the lower connecting sleeves, and right spherical pits open rightwards are formed in the right sides of the lower connecting sleeves. Rigid connecting rods are connected between the adjacent left pits and right pits, left spheres clamped inside the right pits are arranged at the left ends of the rigid connecting rods, and right spheres clamped inside the left pits are arranged at the right ends of the rigid connecting rods. The different-change spiral spring has the advantage that when the spiral spring is bent in two opposite directions, different bending degrees can be formed.

Description

technical field [0001] The invention relates to the technical field of springs, in particular to a variational coil spring. Background technique [0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials are deformed under the action of external force, and return to their original shape after the external force is removed. Springs are generally made of spring steel. There are various types of springs. According to the shape, there are mainly coil springs, scroll springs, leaf springs, special-shaped springs, etc. However, in some workplaces, it is necessary to use the coil spring to realize the function of the leaf spring, and when the coil spring bends to one side and the other side, it needs to form different bending degrees, which is mostly difficult to achieve for coil springs . Contents of the invention [0003] The object of the present invention is to provide a variable-variation coil spring, which has the characteristi...
