The outer wall of the limit block 11 is fixedly connected with an L plate 12, and the limit block 11 can be moved by the L plate 12. A fixed seat 13 is provided at the left end of the mounting seat 5. The fixed seat 13 is installed at the eight-position shift cylinder installation position on the car. The right end inner wall of the plug plate 9 is fixedly connected to one end of the positioning spring 10. When the limit block 11 moves to the right, the positioning spring 10 will be compressed.

The positioning spring The other end of 10 is fixedly connected to the right end of the limit block 11, the outer wall of the plug plate 9 is plugged into the inner wall of the fixing seat 13, the limit block 11 is slidably connected to the inner wall of the plug plate 9, and the plug plate 9 is provided with slots corresponding to the limit block 11 and the L plate 12, so that the limit block 11 and the L plate 12 can slide along the plug plate 9, the L plate 12 is slidably connected to the inner wall of the plug plate 9, the L plate 12 passes through and is slidably connected to the inner wall of the mounting seat 5, the mounting seat 5 is provided with slots corresponding to the L plate 12, so that the L plate 12 can slide along the inner wall of the mounting seat 5, the limit block 11 is plugged into the inner wall of the fixing seat 13, and the inner wall of the fixing seat 13 is provided with slots, so that the limit block 11 can be plugged therewith to limit the entire mounting seat 5.

[0033] Reference Figure 1-Figure 3 The inner wall of the left end of the sleeve 6 is fixedly connected to one end of the return spring 7. When the movable plug 8 moves to the left, the return spring 7 will be compressed. When resetting, the elastic force of the return spring 7 is used to return the movable plug 8. The other end of the return spring 7 is fixedly connected to the left end of the movable plug 8. The piston of the movable plug 8 is connected to the inner wall of the sleeve 6. The guide mechanism includes a guide tube 4, which passes through and is slidably connected to the inner wall of the fixed block 2. The left end of the guide tube 4 is fixedly connected to the outer wall of the right end of the mounting seat 5. The bottom end of the wedge block 3 is plugged into the outer wall of the guide tube 4. The outer wall of the guide tube 4 is provided with a plurality of notches, which can allow the wedge block 3 to be plugged into the guide tube 4, providing a part of the resistance to reduce vibration.

[0034] Working principle: First, when the cylinder sleeve 1 and the mounting seat 5 need to be installed, just insert the plug plate 9 into the corresponding opening of the fixing seat 13, let the right end outer wall of the fixing seat 13 squeeze the inclined surface of the limit block 11, let the limit block 11 and the L plate 12 move to the right and compress the positioning spring 10. When the limit block 11 coincides with the inner wall notch of the fixing seat 13, use the reverse elastic force of the positioning spring 10 to reset the limit block 11 and the L plate 12, let the limit block 11 be plugged into the inner wall notch of the fixing seat 13, and complete the installation of the cylinder sleeve 1 and the mounting seat 5.

[0035] When the cylinder sleeve 1 is in use, when the vibration is transmitted from the car to the fixed seat 13, the fixed block 2 and the guide tube 4 will slide relative to each other, and the resistance generated by the separation and overlap of the notch of the outer wall of the wedge block 3 and the guide tube 4 will slow down the vibration at the fixed seat 13. At the same time, the sleeve 6 and the movable plug 8 correspond to the piston movement and compress the return spring 7, and the reverse elastic force of the return spring 7 is used to alleviate part of the vibration. When the sleeve 6 and the movable plug 8 slide relative to each other, the movable plug 8 will compress the air in the sleeve 6 to generate a certain pressure, and the air in the sleeve 6 will be slowly discharged from the circular hole on the outer wall of the sleeve 6 to alleviate part of the vibration. When there is no vibration, the reverse elastic force of the return spring 7 will be used to reset the movable plug 8 and the fixed block 2, so that the wedge block 3 is continuously inserted and reset with the outer wall of the guide tube 4. At the same time, when the movable plug 8 is reset, air will be drawn into the sleeve 6 from the outside.

[0036] When it is necessary to disassemble the cylinder sleeve 1 and the mounting seat 5, it is only necessary to press the L-plate 12 to allow the L-plate 12 to move the limit block 11 to the right and compress the positioning spring 10, so that the limit block 11 and the inner wall groove of the fixing seat 13 are separated, and the opening of the fixing seat 13 can be separated from the plug plate 9 to complete the disassembly. Finally, release the L-plate 12 and use the reverse elastic force of the positioning spring 10 to restore the limit block 11 and the L-plate 12.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
