[0024] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0025] Embodiment one

[0026] Referring to Figures 1-4 A shock absorber shock absorbing bush with good durability, comprising a main assembly 1; the main assembly 1 comprises an outer metal pipe 11, an inner metal pipe 12 is arranged on the outer metal pipe 11; an end plate 13 is symmetrically arranged on the outer metal pipe 11; a shock absorbing bush body 14 is arranged on the outer metal pipe 11; a disassembly assembly 2 is symmetrically arranged on the outer metal pipe 11, each set of the disassembly assembly 2 comprises: a mounting shell 21 fixedly connected to the outer side wall of the outer metal pipe 11; a threaded rod 22 rotatably connected to the inner side wall of the mounting shell 21, and a plurality of threaded rods 22 are uniformly arranged; a gear 23, each outer side wall of the threaded rod 22 is fixedly connected with a gear 23; a limiting block 24, each outer side wall of the gear 23 is threadedly connected with a limiting block 24, and each limiting block 24 penetrates the outer metal pipe 11; a rotating ring 25 rotatably connected to the inner side wall of the mounting shell 21; a gear ring 26 fixedly connected to the bottom of the rotating ring 25, and each gear 23 is engaged with the rotating ring 25; a limiting groove 27 is arranged on the outer side wall of the end plate 13; the bottom of the rotating ring 25 is fixedly connected with an anti-skid sleeve 5; the width of the rotating ring 25 is equal to the inner side width of the mounting shell 21.

[0027] In use, the operator inserts the damping bushing body 14 into the outer metal pipe 11, then places the sealing plate 13 against the inner metal pipe 12, aligns the plurality of limiting grooves 27 on the sealing plate 13 with the plurality of limiting blocks 24, then rotates the rotating ring 25 on the mounting shell 21 to drive the gear ring 26 and the plurality of gears 23 to rotate, and the plurality of gears 23 drive the threaded rods 22 and the limiting blocks 24 to move, so that the plurality of limiting blocks 24 are inserted into the plurality of limiting grooves 27 to limit and fix the sealing plate 13. When replacement is needed, the sealing plate 13 can be disassembled by reversing the rotating ring 25, thereby facilitating the operator to use and replace the sealing plate 13, and improving the durability of the device. When the rotating ring 25 moves, the anti-skid sleeve 5 moves simultaneously, thereby increasing the friction between the rotating ring 25 and the mounting shell 21 through the anti-skid sleeve 5, avoiding self-rotation of the rotating ring 25 caused by external vibration, and causing unstable fixation of the sealing plate 13, thereby improving the stability of the device. When the rotating ring 25 rotates, it rotates against the inner side of the mounting shell 21, thereby avoiding dust and other debris from entering the inside of the mounting shell 21 through the gap between the mounting shell 21 and the rotating ring 25, causing the inside of the mounting shell 21 to be blocked, thereby improving the safety of the device.

[0028] Embodiment Two

[0029] Referring to Figures 1-4 On the basis of embodiment one, an auxiliary function is added;

[0030] Each of the gear 23 outer side wall is rotatably connected with a baffle 6, and each of the baffle 6 is fixedly connected to the inner side wall of the mounting shell 21. The outer side wall of the sealing plate 13 is fixedly connected with a positioning block 4. The top of the rotating ring 25 is provided with anti-skid lines.

[0031] In use, when the threaded rod 22 drives the limiting block 24 to move, the movement range of the limiting block 24 is limited by the baffle 6, avoiding the operator from being inconvenient to check the position of the limiting block 24, causing the limiting block 24 to collide with the gear 23 and be damaged, thereby improving the safety of the device. When the sealing plate 13 is installed, the positioning block 4 on the sealing plate 13 is placed into the positioning groove on the outer metal pipe 11, so that the plurality of limiting grooves 27 on the sealing plate 13 are aligned with the plurality of limiting blocks 24, thereby reducing the time for the operator to manually align, thereby improving the convenience of the device. The anti-skid lines on the top of the rotating ring 25 can increase the friction between the rotating ring 25 and the operator's fingers, facilitating the operator to drive the rotating ring 25, thereby improving the work efficiency of the operator.

[0032] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
