Problems solved by technology

[0004] (1) The safety and versatility of the device in this patent is not good: the structure and specifications of the coil spring of the automobile suspension are various, but the structure of the pull claw in the device cannot be applied to springs with different spring diameters. During the process, it may cause unstable clamping. In addition, the spring stiffness is generally relatively large. When the spring is compressed, it may pop out suddenly, causing adverse consequences of injuring others.
[0005] (2) The device in this patent is easy to damage parts: the device directly uses the claws to clamp and compress the coil spring, because the clamping force of the coil spring is very large when the coil spring is compressed, it is easy to damage the surface of the spring
[0006] (3) The device in this patent is operated with low work efficiency and high labor intensity
And it cannot be used alone, it must be used in pairs. When using it, the two sides of the spring must be gradually and evenly compressed, otherwise the spring will be unevenly stressed and the compression amount on both sides will be different. Not only can the disassembly and assembly of the suspension not be completed, And there are potential safety hazards, so the actual operation efficiency is low
In addition, since the device does not have an auxiliary force device, the labor intensity is increased
[0007] (4) The device is inconvenient and inflexible to operate: the coil spring has a coil lift, and the suspension assembly is disassembled only by compressing the spring, so it is difficult to ensure the shock absorber piston rod, spring and spring seat, etc. Perfect alignment, which will affect the smooth assembly of other components in the suspension
[0009] (1) The device is easy to damage parts. Although the device in the patent adopts the method of clamping and compressing the coil spring at one end, the clamping force directly acting on the spring is still very large, and the surface layer of the spring is easily damaged.
[0010] (2) The actual operation of the device is complicated and the efficiency is not high
This patent is composed of multiple parts, and the structure is quite complicated. Many steps are required to clamp the shock absorber and the spring. It is not labor-saving to operate the handle to compress the spring, and it is easy to get stuck after a long time.
[0011] (3) The device is expensive to manufacture, takes up a lot of space, and is not easy to move or carry

Embodiment 1

[0065] like image 3 and Figure 4 Shown, a kind of portable automobile suspension dismounting device is made up of upper plate 10, movable plate 20, lower plate 90, circular column 70, jack 80, rocking bar 60 etc. There is a hole 30 in the middle of the upper plate 10, and the upper plate 10 can adjust the assembly height of the suspension assembly through the nut 50 on the upper part of the circular column 70; , the movable plate 20 can rotate around the bolt 50, the positioning pin 51 needs to be buckled when the upper plate 10 is closed, and the positioning pin 51 needs to be taken out when the upper plate 10 is opened; The surface and the upper surface of the movable plate 20 are smooth; the jack 80 is connected and fixed with the lower plate 90 by nuts, and the center of the jack 80 is aligned with the center of the hole 30 of the upper plate 10 to ensure that the parts of the suspension assembly are in the same vertical position during the disassembly process. in a st...

Embodiment 2

[0067] like Figure 5 Shown, by the first upper plate 11, the second upper plate 12, lower plate 90, square column 41, jack 80, rocking bar 60 forms. A round hole 21 is arranged between the first upper plate 11 and the second upper plate 12, and the first upper plate 11 and the second upper plate 12 can adjust the assembly height of the suspension assembly through the threaded nut at the upper thread of the square column 41; The first upper plate 11 and the second upper plate 12 are positioned and connected together by threaded nuts, connecting reinforcing plates 71 and bolts and nuts 81, wherein the threaded nuts play a positioning role, and a certain gap is left between the upper and lower nuts to facilitate the first The first upper plate 11 and the second upper plate 12 are disassembled and taken out, and the connecting reinforcement plate 81 and the bolts and nuts 81 are connected and fixed; the jack 61 is connected and fixed with the lower plate 91 by bolts.
