Description

Technical Field

[0001] This utility model belongs to the automotive field, specifically, it relates to a shock absorber spring pre-compression device. Background Technology

[0002] Shock absorber springs are an important component of a car's suspension system. Their main functions are to cushion road impacts, support the vehicle's weight, and maintain vehicle stability. They work in conjunction with dampers to ensure both driving comfort and handling.

[0003] When installing springs, they need to be pre-compressed. The compression force of the spring makes the spring and shock absorber fit together better. Common spring pre-compression devices use symmetrical worm gears on both sides to apply pressure to the spring through the structure of the worm gear wall. Although the spring can be compressed, after adjusting the structure of the worm gear wall on one side, there is a high probability that the spring will release pressure and detach from the structure due to the different forces on both sides, which could injure workers. Therefore, there is an urgent need for a shock absorber spring pre-compression device to prevent the spring from flying off.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a shock absorber spring pre-compression device includes: a handle 20, which is a semi-circular ring. Screws 21 are symmetrically arranged at both ends of the handle 20. Each screw 21 is a cylinder with opposing threads on its arc surface. A pressure claw 22 is symmetrically threaded onto the wall surface of each screw 21. The pressure claw 22 is a fan-shaped plate. A limiting disc 23 is fixedly connected to the upper and lower ends of each screw 21. The limiting disc 23 is disc-shaped. Arc-shaped grooves are formed on the walls of the symmetrical pressure claws 22 facing each other. This is existing technology and will not be described in detail here.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a compression structure is installed on the wall of the handle 20 to control the position of the pressure claw 22. The compression structure includes: a movable block 30, a through plate 35, a synchronous claw 36, and a protective rod 37. The movable blocks 30 are symmetrically arranged at both ends of the handle 20. The through plate 35 is symmetrically fixedly connected to the wall surface of each pressure claw 22 with an arc groove. The synchronous claw 36 is fixedly connected to the wall surface of each set of symmetrical through plates 35. The protective rod 37 is symmetrically fixedly connected to the front and rear wall surfaces of each synchronous claw 36.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the movable block 30 is a rectangular block, the through plate 35 is a rectangular plate, and the synchronizing claw 36 is a rectangular plate. Each side of the symmetrical synchronizing claw 36 has an arc-shaped groove on its wall facing the opposite direction, consistent with the wall surface of the pressure claw 22. The protective rod 37 is an L-shaped rod, obliquely placed on the wall surface of the synchronizing claw 36. The compression structure also includes a limiting groove 31, a slider 32, a sleeve 33, and an anti-shifting rod 34. The limiting groove 31 is opened inside the cavity of the movable block 30. The slider 32 is symmetrically fixedly connected to the upper and lower walls at both ends of the handle 20. The sleeve 33 is fixedly connected to the walls of the symmetrical movable blocks 30 facing the opposite direction. The anti-shifting rod 34 is located on each side of the synchronizing claw 36. The upper and lower walls of each sleeve 33 are symmetrically fixedly connected. The limiting groove 31 is a groove with a cross-shaped cross section. The slider 32 is a rectangular block. The limiting groove 31 can adapt to the end of the handle 20 and the sliding of the symmetrical slider 32. The sleeve 33 is a cylindrical tube. The cavity of the sleeve 33 can adapt to the rotation of the screw 21. The anti-shifting rod 34 is cylindrical. The top of each anti-shifting rod 34 can contact the wall surface of the corresponding limiting plate 23. The anti-shifting rod 34 can also pass through the wall surface of the pressure claw 22. The wall surface of the pressure claw 22 is also provided with a circular groove adapted to the size of the anti-shifting rod 34. The wall surface of the synchronizing claw 36 is provided with a rectangular groove adapted to the screw 21 and the anti-shifting rod 34 passing through.

[0030] In practical use, the symmetrical movable blocks 30 are slid along the two end walls of the pressure claws 22 and the pressure claws 22 on each side are adapted to the size of the spring. Then, the arc grooves on the walls of each set of symmetrical pressure claws 22 are fitted with the walls of the spring. As the pressure claws 22 and the spring are fitted, the synchronizing claws 36 can also contact and fit with the walls of the spring. At this time, the spring will be located between the symmetrical protective rods 37. Then, the screw 21 is rotated. As the screw 21 rotates, each set of symmetrical pressure claws 22 on both sides will move towards each other. As the pressure claws 22 move, the spring can be compressed. After the pressure claws 22 on both sides are adjusted, the spring can be fully compressed. At this time, the spring can be installed into the corresponding shock absorber.

[0031] In summary, by setting up a compression structure, the spring can be compressed synchronously by the synchronous claw 36, and the spring can be blocked by the protective rod 37, which effectively prevents the spring from breaking out between the symmetrical pressure claws 22.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the sleeve 33 has an anti-detachment structure on its wall surface. The anti-detachment structure includes an anti-detachment hook 38. The anti-detachment hook 38 is rotatably connected to the wall surfaces of the symmetrical sleeves 33 facing each other. The anti-detachment hook 38 is in the shape of a hook and is placed horizontally on the wall surface of the sleeve 33. The arc surfaces of the symmetrical anti-detachment hooks 38 face each other.

[0033] In practical use, when adjusting the position of the movable block 30, hook the anti-disengagement hook 38 on each side onto the wall of the spring to be compressed;

[0034] In summary, by setting up an anti-detachment structure and using the anti-detachment hook 38 to hook the spring wall, the spring is further prevented from detaching from the device.

[0035] Working principle: The symmetrical movable blocks 30 slide along the two end walls of the pressure claws 22, causing each symmetrical pressure claw 22 on each side to adapt to the size of the spring. Then, the arc-shaped grooves on the walls of each set of symmetrical pressure claws 22 are aligned with the walls of the spring. As the pressure claws 22 and the spring are aligned, the synchronizing claws 36 can also contact and align with the walls of the spring. At this time, the spring will be located between the symmetrical protective rods 37. Then, the screw 21 is rotated. As the screw 21 rotates, each set of symmetrical pressure claws 22 on both sides will move towards each other. As the pressure claws 22 move, they can drive the spring to compress. After the pressure claws 22 on both sides are adjusted, the spring can be fully compressed. At this time, the spring can be installed into the corresponding shock absorber.
