[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figures 1-4 As shown, this utility model provides a technical solution: a double-spring motorcycle rear shock absorber, including a damper 1. Fixed plates 11 are fixedly installed at both ends of the damper 1. A first spring 12 is fixedly installed at one opposite end of the fixed plates 11, and a second spring 13 is fixedly installed at one end of the damper 1. One end of the upper fixed plate 11 is fixedly connected to the second spring 13. A connecting seat 14 is movably connected to one end of each fixed plate 11. A connecting ring 15 is fixedly installed at one end of each connecting seat 14. Symmetrically distributed support members 16 are fixedly installed at the top of each fixed plate 11. One end of each component 16 is rotatably fitted with an L-shaped block 17. The outer side of each connecting seat 14 is provided with symmetrically distributed slots 18. One end of the L-shaped block 17 is movably engaged with the inner side of the slot 18. The inner side of each slot 18 is fixedly installed with symmetrically distributed third springs 19. One end of each third spring 19 is fixedly connected to a horizontal plate 20. One end of each horizontal plate 20 is fixedly installed with symmetrically distributed insert rods 21. One end of each insert rod 21 is slidably inserted into the inner side of the L-shaped block 17. The outer side of each connecting seat 14 is threaded with symmetrically distributed bolts 22. One end of each bolt 22 is threadedly connected to the L-shaped block 17.

[0021] Each end of the connecting seat 14 has a hidden opening 23. The inner side of the hidden opening 23 is rotatably secured with a rotating shaft 24. The outer side of the rotating shaft 24 is fixedly connected with a handle 25. One end of the handle 25 is fixedly connected with a magnetic column 26. One end of the magnetic column 26 is movably connected to the inner side of the hidden opening 23.

[0022] By adopting the above technical solution, the handle 25 can be easily hidden in the concealed opening 23 by rotating the shaft 24. The magnetic attraction between the magnetic column 26 and the fixed plate 11 makes the handle 25 hidden and stable. However, rotating the shaft 24 makes it easy to pull the handle 25 out of the concealed opening 23, thus making it convenient for staff to use the handle 25 to move the equipment. The structure is ingenious, easy to hide, and does not affect the connection and movement of other components.

[0023] Each of the support members 16 is fixedly fitted with symmetrically distributed limiting rings 27, and the opposite end of the limiting ring 27 is in movable contact with the corresponding L-shaped block 17.

[0024] By adopting the above technical solution, the L-shaped block 17 is limited by setting a limiting ring 27.

[0025] One end of each connecting seat 14 is slidably inserted with symmetrically distributed T-shaped rods 28, and one end of each T-shaped rod 28 is fixedly connected to the corresponding horizontal plate 20.

[0026] By adopting the above technical solution, the T-shaped rod 28 is set to facilitate the pulling of the horizontal plate 20 and the movement of the insertion rod 21.

[0027] Anti-friction sleeves 29 are fixedly installed on the inner side of the connecting ring 15.

[0028] By adopting the above technical solution, the wear of the connecting ring 15 during the movement of the motorcycle frame is reduced by setting the anti-wear sleeve 29.

[0029] One end of each connecting seat 14 is fixedly equipped with symmetrically distributed magnetic suction plates 30, and one end of the magnetic suction plate 30 is slidably inserted into the inner side of the fixed plate 11.

[0030] By adopting the above technical solution, the connecting seat 14 is positioned by magnetically inserting the magnetic plate 30 into the fixing plate 11, thereby improving the stability of the connecting seat 14.

[0031] Working principle: First, the connecting ring 15 is connected to the motorcycle frame. When encountering bumpy roads during motorcycle operation, the damper 1 and the second spring 13 work together with the first spring 12 to achieve double-spring shock absorption. Then, when the connecting ring 15 needs to be replaced due to severe wear or deformation caused by overpressure during long-term connection with the frame, the bolt 22 is manually removed. The bolt 22 is disengaged from the L-shaped block 17. Then, the T-shaped rod 28 is pulled to move the cross plate 20. The third spring 19 is compressed, and the cross plate 20 drives the insertion rod 21 to be pulled out from the L-shaped block 17. Then, the L-shaped block 17 is rotated to disengage from the slot 18, making it easy to disassemble and remove the connecting seat 14 and the connecting ring 15. The new connecting seat 14 and connecting ring are then installed. The connecting ring 15 aligns with the fixed plate 11, the L-shaped block 17 snaps into the slot 18, the third spring 19 pushes the insertion rod 21 into the L-shaped block 17, and the bolt 22 is used to fix the L-shaped block 17 again, thus completing the installation. This enables convenient installation, removal and replacement of the connecting ring 15, improving maintenance convenience and indirectly enhancing safety. The rotation of the pivot 24 makes it easy to hide the handle 25 in the concealed opening 23. The magnetic column 26 and the fixed plate 11 magnetically attract the handle 25 to keep it hidden and stable. However, rotating the pivot 24 makes it easy to pull the handle 25 out of the concealed opening 23, making it convenient for workers to use the handle 25 to move the equipment. The structure is ingenious, easy to hide, and does not affect the connection and movement of other components.

[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
