DETAILED DESCRIPTION

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model provides a length-adjustable motorcycle shock absorber. Figure 1-5 As shown, it includes: a shock absorbing cylinder 1, the outer surface of the shock absorbing cylinder 1 is sleeved with a sleeve 2, and the top of the sleeve 2 is fixedly connected to a limiting cover 3; a filling port 4 is fixedly connected to one side of the bottom of the shock absorbing cylinder 1, and a through hole 5 is opened near the filling port 4 of the shock absorbing cylinder 1, and a metal filter screen 6 is arranged inside the through hole 5, and the metal filter screen 6 is fixedly connected to the shock absorbing cylinder 1, and a conical spring 7 is arranged on the side of the metal filter screen 6 close to the filling port 4, and a sealing bead 8 is arranged on the side of the conical spring 7 away from the metal filter screen 6, and the sealing bead 8 is adapted to the filling port 4; a rotating mechanism 9 for adjusting the shock absorbing performance of the shock absorber is arranged on the outer surface of the shock absorbing cylinder 1; a screw mechanism 10 for adjusting the overall length of the shock absorber is arranged inside the sleeve 2.

[0022] It should be noted that, after the user aims the oil gun muzzle at the filling port 4 and presses the oil gun, the lubricating oil inside the oil gun pushes the sealing bead 8, so that after the sealing bead 8 is separated from the filling port 4, the lubricating oil enters the interior of the through hole 5 from the gap between the sealing bead 8 and the filling port 4, and then enters the interior of the shock absorber from the through hole 5. When the user stops pressing the oil gun, the conical spring 7 produces elastic recovery to push the sealing bead 8 to the filling port 4, so that the filling port 4 is sealed to prevent the lubricating oil inside the shock absorber from leaking, thereby simplifying the user's workflow for adding lubricating oil to the shock absorber, and solving the problem that the motorcycle shock absorber does not have the function of facilitating the user to add lubricating oil to the shock absorber, resulting in the user needing to disassemble the shock absorber to add lubricating oil to the shock absorber when the user needs to add lubricating oil to the shock absorber, and the workflow for adding lubricating oil is relatively complicated.

[0024] In this embodiment, the user rotates the hexagonal fixing block 12 with the help of an adjustable wrench, so that the hexagonal fixing block 12 drives the internal threaded sleeve 11, and the internal threaded sleeve 11 is raised and lowered while rotating on the surface of the shock absorber cylinder 1. When the hexagonal fixing block 12 is raised and lowered, the hardness of the spring 14 is adjusted by cooperating with the limit cover 3, thereby achieving the purpose of adjusting the buffering performance of the shock absorber.
