[0025] By providing the disassembly assembly 5, it is convenient for personnel to install and disassemble the hydraulic cylinder, and the operation can be completed without using professional tools, which is simple and easy to understand.

A screw groove 8 is provided on the surface of the mounting plate 4;

[0027] During installation, the operator holds the pull rod 11 and places the cylinder body 1 on the two mounting plates 4, so that the protrusion 6 on the mounting plate 4 is inserted into the interior of the disassembly assembly 5. Then, the turning handle 508 is turned to cooperate with the second gear 507, the first gear 506, the two-way threaded rod 502, the movable plate 503, and the connecting rod 504 to drive the block 505 into the slot 7 to fix the cylinder body 1. Otherwise, it can be disassembled. The operation can be completed without using professional tools. It is simple and easy to understand.

[0028] See also Figures 1 to 2 , the interior of the cylinder body 1 is slidably connected to the piston rod 3, and a buffer assembly 9 is provided between the piston rod 3 and the cylinder head 2. The buffer assembly 9 includes an airbag 901, a spring 902, a pressure plate 903, a connecting column 904, and a fixing ring 905.

[0030] In the present invention, the working principle of the device is as follows:

[0031] When installing the cylinder body 1, the personnel pre-install the mounting plate 4 in the designated area through the screw groove 8. After the installation is completed, the personnel hold the pull rod 11 and place the cylinder body 1 on the two mounting plates 4, so that the protrusion 6 on the mounting plate 4 is inserted into the interior of the disassembly assembly 5, and then turn the handle 508 to drive the second gear 507 to rotate, which drives the bidirectional threaded rod 502 to rotate through the first gear 506. Since the bidirectional threaded rod 502 is provided with two threads in opposite directions on the surface, it can drive the two movable plates 503 to move in different directions at the same time, so that the two movable plates 503 move away from each other, and at the same time drive the connecting rod 504 and the block 505 to move, and finally make the block 505 enter the groove 7 inside the protrusion 6 to fix the cylinder body 1. Conversely, when the cylinder body 1 needs to be disassembled, it is only necessary to rotate the handle 508 in the opposite direction to make the two blocks 505 approach each other. When the block 505 is completely disengaged from the groove 7, it can be disassembled.

[0032] When the piston rod 3 performs reciprocating telescopic motion, the piston rod 3 will drive the pressure plate 903 to move horizontally, and at the same time drive the connecting column 904 to move horizontally, thereby driving the fixing ring 905 to move horizontally. When the piston rod 3 moves to the end of the stroke, it drives the fixing ring 905 to move to the airbag 901 and squeezes the airbag 901, and at the same time compresses the spring 902. The airbag 901 and the airbag 901 can absorb the driven impact force, play a buffering role, so as to improve the service life of the hydraulic pump. When the fixing ring 905 stops squeezing the airbag 901, the airbag 901 and the spring 902 will be reset due to the action of the force, and can resume working when squeezed next time.
