[0035] Embodiment 1

[0036] As Figure 1-2 shown, an embodiment of the present utility model provides a shock absorber that is convenient for installation, including a cylinder block 110, an upper mounting ring 120 and a lower mounting ring 130 respectively arranged at both ends of the cylinder block 110, a buffer spring 140 arranged between the two mounting rings, an adjusting ring 200, a mounting seat 300, and a buffer gasket 400. The adjusting ring 200 is threadedly connected to the upper end of the cylinder block 110 and abuts against one end of the buffer spring 140. Specifically, a threaded portion is provided at the upper end of the cylinder block 110, and the adjusting ring 200 meshes with the threaded portion. One end of the mounting seat 300 is made of an elastic material and is provided with a slot 310 in the vertical direction to be sleeved on the lower mounting ring 130, and the mounting seat 300 forms a step 320. One end of the buffer gasket 400 is connected to the end of the buffer spring 140 away from the adjusting ring 200, and one end abuts against the step 320 under the action of the buffer spring 140. By rotating the adjusting ring 200, the elastic stiffness of the buffer spring 140 can be adjusted, and at the same time, the height of the entire shock absorber can also be adjusted, which can be applicable to different vehicles and increases the applicability for vehicles with different chassis heights.

[0037] In the embodiment of the present utility model, when the buffer spring 140 needs to be replaced, by moving the buffer spring 140 to separate the buffer gasket 400 from the mounting seat 300, the mounting seat 300 can be detached from the lower mounting ring 130, and then the buffer spring 140 can be taken out for replacement, which is very convenient.

[0038] As Figure 1-2 shown, in a preferred embodiment of the present utility model, a plurality of card slots 210 are equidistantly arranged on the circumferential wall of the adjusting ring 200 along its circumferential direction. By providing the plurality of card slots 210, it is possible to use an external component to be clamped in the card slots 210, which is convenient and labor-saving for operating the adjusting ring 200.

[0039] As Figure 3 shown, in the embodiment of the present utility model, a partition 330 is formed inside the mounting seat 300. One end of the partition 330 is provided with a guiding groove 331 communicating with the slot 310. The partition 330 is further provided with an arc-shaped through groove 332 connected to the guiding groove 331. The arc-shaped through groove 332 is adapted to the piston rod of the cylinder block 110. When installing the mounting seat 300, the mounting seat 300 is sleeved on the piston rod of the cylinder block 110 through the slot 310, the guiding groove 331 and the arc-shaped through groove 332. At the same time, the partition 330 abuts against the top of the lower mounting ring 130. Then, the buffer gasket 400 of the buffer spring 140 is placed on the step 320 of the mounting seat 300. At this time, the mounting seat 300 is installed. The piston rod can also move up and down in the arc-shaped through groove 332. In addition, when the shock absorber is impacted, it will also drive the buffer spring 140 to apply pressure to the mounting seat 300, making it firmly abut against the lower mounting ring 130 and preventing it from detaching from the lower mounting ring 130.

[0040] As Figure 1-2 shown, in the embodiment of the present utility model, an installation sleeve 500 is provided on the partition 330, and the installation sleeve 500 is closely fitted with the inner wall of the mounting seat 300. A cleaning sleeve 600 is sleeved on the piston rod of the cylinder block 110. The installation sleeve 500 can be sleeved on the cleaning sleeve 600. The cleaning sleeve 600 remains stationary under the action of the installation sleeve 500. Therefore, when the piston rod moves up and down, the cleaning sleeve 600 can remove the particulate dust adhering to the outer surface of the piston rod, prevent the dust from scratching the outer surface of the piston rod, ensure the sealing strength of the device, and increase the service life of the device.

[0041] As Figure 3 shown, in the embodiment of the present utility model, a plurality of through holes are provided in both the partition 330 and the installation sleeve 500. Specifically, the plurality of through holes are equidistantly arranged along the circumferential direction of the installation sleeve 500. By providing the plurality of through holes, while ensuring the strength and rigidity of the partition 330 and the installation sleeve 500, the overall weight of the installation sleeve 500 can be effectively reduced, the material cost can be reduced, and it is convenient to use.

[0042] As Figure 1-2 shown, in the embodiment of the present utility model, a fixing ring 700 is provided on the outer peripheral surface of the cylinder block 110. The fixing ring 700 can enhance the overall strength of the cylinder block 110. The upper mounting ring 120 is sleeved on the upper end of the cylinder block 110 and abuts against the fixing ring 700. Such a design simplifies the installation process, and the installation can be completed without additional complex tools and steps, effectively improving the production efficiency and reducing the installation cost. At the same time, it makes disassembly and maintenance more convenient. The staff only needs to simply disassemble the fixing ring 700 to perform maintenance or replace components.

[0043] Embodiment 2

[0044] As Figure 4 shown, based on the further improvement of the above-mentioned Embodiment 1, the difference between this embodiment and the above-mentioned Embodiment 2 is that in the embodiment of the present utility model, the shock absorber further includes a limit sleeve 800 with an opening at one end. The limit sleeve 800 is made of an elastic material. The limit sleeve 800 is sleeved on the upper end of the cylinder block 110 and blocks between the adjusting ring 200 and the fixing ring 700. After the elastic stiffness of the buffer spring 140 is adjusted by rotating the adjusting ring 200, the limit sleeve 800 is sleeved between the adjusting ring 200 and the mounting ring. Therefore, when the shock absorber is impacted, it will also drive the buffer spring 140 to expand and contract for buffering outside the cylinder block 110. At this time, the limit sleeve 800 can absorb part of the vibration and impact energy brought by the buffer spring 140 to the adjusting ring 200, further reducing the impact on the adjusting ring 200 and improving the overall shock absorption effect of the shock absorber. It should be understood that the overall height of the limit sleeve 800 can be set in multiple specifications according to the moving distance of the adjusting ring 200 to meet the different distances between the adjusting ring 200 and the mounting ring. Of course, in another embodiment, a flat opening can also be provided in the threaded portion. The flat opening is provided with a plurality of scale grooves along the axial direction of the cylinder block 110. Each scale groove can be correspondingly provided with a limit sleeve 800. When adjusting the adjusting ring 200, the moving distance can be known through its corresponding scale groove to select a suitable limit sleeve 800.

[0045] As Figure 5 shown, in the embodiment of the present utility model, the limit sleeve 800 includes a small end 810 of the sleeve body and a large end 820 of the sleeve body. The small end 810 of the sleeve body is adapted to the inner diameter of the upper end of the cylinder block 110; a threaded portion is provided at the upper end of the cylinder block 110, and the adjusting ring 200 is engaged with the threaded portion. The inner diameter of the large end 820 of the sleeve body is larger than the outer diameter of the threaded portion. When the limit sleeve 800 is sleeved on the cylinder block 110, since the inner diameter of the large end 820 of the sleeve body is larger than the outer diameter of the threaded portion, the limit sleeve 800 will not contact the threaded portion, preventing the impact brought by the adjusting ring 200 from wearing the limit sleeve 800, and the small end 810 of the sleeve body fits with the inner diameter of the cylinder block 110, preventing the limit sleeve 800 from slipping off the cylinder block 110, improving the reliability of the overall structure of the shock absorber.

[0046] As Figure 5 shown, in an embodiment of the present utility model, a convex rib 830 is formed on the side wall of the limit sleeve 800. Specifically, the convex rib 830 extends from one end of the limit sleeve 800 to the other end. The structure of the convex rib 830 can increase the rigidity and strength of the side wall of the limit sleeve 800, enabling the limit sleeve 800 to withstand greater impact force, and at the same time can also absorb and disperse part of the impact and vibration.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
