[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The specific embodiments described herein are merely used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] This invention provides a damper with adjustable capacity, for example, such as... Figure 1The diagram shows a body 1, a piston rod 2 located within the body 1, and a piston 3 connected to the piston rod 2. The body 1 also includes an outer tube 101 and a working cylinder 102 located within the outer tube 101. The working cylinder 102 has a bottom valve 103 and a guide 104 at each end. The bottom valve 103 controls the hydraulic fluid, the guide 104 restricts the position of the piston rod 2, and an oil seal is provided between the guide 104 and the piston rod 2 to improve sealing.

[0037] Furthermore, both the piston 3 and the piston rod 2 are located within the working cylinder 102. A bottom cover 105 is installed at the bottom end of the outer tube 101. Both the bottom cover 105 and the end of the piston rod 2 are fitted with spherical bearings 107 via connecting rods 106. The working cylinder 102, the outer tube 101, and other components are used to hold hydraulic oil. Their specific structure and principle can be found in existing hydraulic dampers, and will not be elaborated here. A limiting seat 201, adapted to the guide 104, is connected to the outside of the piston rod 2, which restricts the movement range of the piston rod 2, thus serving a limiting function.

[0038] To improve the adaptive buffering effect of the damper, such as Figure 2 and Figure 3 As shown, this application provides an adjustment assembly 4 at the bottom end of the piston rod 2. The adjustment assembly 4 includes a through hole 401 opened at the bottom end of the piston rod 2 and a screw plug adjustment part located in the through hole 401. When the piston 3 is working, the screw plug adjustment part can move in the through hole 401 to adjust the flow rate of the through hole 401. It can automatically adjust the buffering force according to the magnitude of the impact, making the shock absorption effect more gentle and improving the shock absorption effect.

[0039] The through hole 401 includes a first threaded hole 402 and a first oil guide hole 403 communicating with the first threaded hole 402; wherein, the central axis of the first threaded hole 402 coincides with the central axis of the piston rod 2, and the central axis of the first oil guide hole 403 is perpendicular to the central axis of the piston rod 2. The first threaded hole 402 is used to connect the plug 404, and the clearance in the first threaded hole 402 can be adjusted by rotating the position of the plug 404 in the first threaded hole 402, thereby adjusting the damping range of the damper. The first threaded hole 402 and the first oil guide hole 403 serve as oil guide holes, facilitating the flow of hydraulic oil.

[0040] Specifically, the screw plug adjustment part includes: a screw plug 404 threadedly connected to the first threaded hole 402, an adjustment hole 405 formed inside the screw plug 404, and an adjustment block 406 movably connected inside the adjustment hole 405. The adjustment block 406 is movably connected in the adjustment hole 405. During operation, the adjustment block 406 can move under the drive of hydraulic oil, and can adjust the buffering force according to the impact force, making the buffering more gentle.

[0041] Additionally, the adjusting hole 405 includes a movable hole 407 and a second oil guide hole 408 connected to the movable hole 407. The second oil guide hole 408 is located at both ends of the screw plug 404. The movable hole 407 and the second oil guide hole 408 connect to the oil passage, allowing hydraulic oil to flow.

[0042] The adjusting block 406 includes a block body 409 and a stop block 410 located outside the block body 409. Both ends of the block body 409 are tapered, and both ends are fitted with compression springs 411. A third oil guide hole 412 is provided in the stop block 410. Under normal conditions, the block body 409 is located in the middle of the movable hole 407 under the force of the compression springs 411. When subjected to impact, the block body 409 moves closer to the second oil guide hole 408 under the influence of hydraulic oil, thereby adjusting the flow rate in the second oil guide hole 408 and effectively reducing the buffering force. Furthermore, the third oil guide hole 412, the second oil guide hole 408, and the first oil guide hole 403 are connected to the working cylinder 102, making the entire oil circuit interconnected.

[0043] To facilitate the installation and removal of the sealing ring and extend its service life, such as... Figures 4-5 As shown, this application provides a sealing ring connecting assembly 5 on the outside of the piston 3, which can better protect the sealing ring, greatly improve the service life of the sealing ring, and thus improve the sealing effect.

[0044] The sealing ring connection assembly 5 includes: a fixed ring 501 fixed to the outside of the piston 3 and a movable ring 502 threaded to the outside of the piston 3, wherein the sealing ring of the piston 3 is located between the fixed ring 501 and the movable ring 502.

[0045] The sealing ring is clamped between the movable ring 502 and the fixed ring 501 through the cooperation of the movable ring 502 and the fixed ring 501, which facilitates the positioning of the sealing ring, makes the installation of the sealing ring convenient, restricts the position of the sealing ring, and prevents its displacement.

[0046] The movable ring 502 includes a left movable ring 503 and a right movable ring 504; the right movable ring 504 and one side of the fixed ring 501 and both sides of the left movable ring 503 are provided with sealing grooves 505 that match the sealing ring.

[0047] When installing the sealing ring, first place the sealing ring 1 in the sealing groove 505 on one side of the fixed ring 501, then thread the left movable ring 503 onto the outside of the piston 3 to clamp the sealing ring 1, then place the sealing ring 2 in the sealing groove 505 on one side of the left movable ring 503, and then thread the right movable ring 504 onto the outside of the piston 3 to clamp the sealing ring 2. This completes the installation of the sealing ring and allows for positioning of the sealing ring, improving the installation efficiency and service life of the sealing ring.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
