[0019] Embodiment 1

[0020] As Figs. 1-3 shown, the first embodiment of the utility model provides a shock absorber, including shock absorber 1, the inner chamber of shock absorber 1 is threadedly connected with shock absorber bushing 2, the lower end of the inner chamber of shock absorber bushing 2 is movably connected with adjusting spring seat 3, the upper end of the inner chamber of shock absorber bushing 2 is slidably connected with shock absorber piston 4, adjusting spring seat 3 and shock absorber piston 4 are fixedly connected with cylindrical spiral compression spring 5, the bottom of shock absorber 1 is fixedly connected with hexagon nut 6, the inner chamber of hexagon nut 6 is threadedly connected with hexagon bolt 7, the top of hexagon bolt 7 extends to the inner chamber of shock absorber bushing 2, and the bottom of adjusting spring seat 3 is movably connected with bearing.

[0021] As Figs. 1-3 shown, shock absorber 1, shock absorber bushing 2, adjusting spring seat 3, shock absorber piston 4 and cylindrical spiral compression spring 5 are used to constitute the main body of shock absorber, since the inner chamber of shock absorber bushing 2 is threadedly connected with shock absorber 1, shock absorber bushing 2 can be removed from the inside of shock absorber 1 by rotating mode, so as to disassemble and replace the worn element, by rotating hexagon bolt 7, the position of adjusting spring seat 3 can be adjusted, so as to adjust the tension state of cylindrical spiral compression spring 5, so that it is suitable for more use states, thereby improving its practicability.

[0022] Embodiment 2

[0023] Referring to Fig. 3 , the second embodiment of the utility model, this embodiment is based on the previous embodiment.

[0024] In this embodiment, the two sides of the surface of shock absorber 1 are fixedly connected with positioning block 9, and the inner chamber of positioning block 9 is slidably connected with positioning column 10.

[0025] The two sides of shock absorber bushing 2 are fixedly connected with fixed sheet 11, one side of fixed sheet 11 is fixedly connected with clamping block 12, the top of positioning column 10 extends to the inner chamber of clamping block 12 and is clamped with the inner chamber of clamping block 12.

[0026] As Fig. 3 shown, by inserting positioning column 10 into the inner chamber of clamping block 12 and positioning with positioning bolt 13, shock absorber 1 and shock absorber bushing 2 can be positioned, so as to prevent shock absorber bushing 2 from loosening due to deflection, thereby improving the stability of the connection of the two.

[0027] Embodiment 3

[0028] Referring to Fig. 1 and 3 , the third embodiment of the utility model, this embodiment is based on the previous two embodiments.

[0029] The upper end and the lower end of the shock-absorbing piston 4 are sleeved with O-rings 8, and the surface of the O-rings 8 is in close contact with the inner wall of the shock-absorbing sleeve 2.

[0030] The top of the clamping block 12 is threadedly connected with a positioning bolt 13, the bottom of the positioning bolt 13 extends into the inner cavity of the positioning column 10 and is threadedly connected with the inner cavity of the positioning column 10, the surface of the shock-absorbing cylinder 1 is sleeved with a pulling ring 14, and the bottom of the positioning column 10 is fixedly connected with the top of the pulling ring 14.

[0032] In use, the cylindrical helical compression spring 5 mainly plays a role in storing energy and rebounding in the shock absorber. When a vibration or impact force acts on the shock absorber, the cylindrical helical compression spring 5 absorbs and stores part of the energy by compression or stretching. The elastic recovery characteristics of the cylindrical helical compression spring 5 enable it to counteract the force, releasing the vibration energy when it weakens, thereby reducing the vibration of the system. The shock-absorbing piston 4 provides damping in the shock absorber, converting the mechanical energy stored in the cylindrical helical compression spring 5 into heat energy through friction or liquid flow, thereby achieving energy dissipation. When external vibration occurs, the cylindrical helical compression spring 5 first absorbs and stores the vibration energy, providing a restoring force. At the same time, the shock-absorbing piston 4 consumes the vibration energy and converts it into heat under the resistance of the liquid or gas, reducing the vibration amplitude of the system. When the worn elements inside the shock-absorbing sleeve 2 need to be replaced, first rotate the positioning bolt 13 to remove it from the inside of the positioning column 10. Then move the pulling ring 14 downward to remove the positioning column 10 from the inside of the clamping block 12. Then, by rotating the shock-absorbing sleeve 2, it can be removed from the inside of the shock-absorbing cylinder 1 to replace the worn elements inside. When the tension state of the cylindrical helical compression spring 5 needs to be adjusted, rotate the hexagonal bolt 7.
