[0031] 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.

[0032] Please see Figures 1-8 The present invention provides the following technical solution.

[0033] Example 1: To address the problems of inconvenient, slow, and stable docking and installation of high-pressure hydraulic cylinders in existing technologies, cumbersome disassembly and assembly operations, and poor stability, this example provides a high-pressure hydraulic cylinder capable of rapid docking and fixing. The cylinder comprises a mounting plate 1, a cylinder body 2, a support rod 3, a support plate 4, a fixing block 5, and fastening bolts 6. The cylinder body 2 is installed through the middle of the mounting plate 1. A fixing block 5 for positioning is inserted into the middle of the support rod 3, and the fixing block 5 is fitted against the upper end of the support plate 4. The fixing block 5 and the support plate 4 are fixed together by fastening bolts 6. The support rod 3 is fixedly connected to the left and right sides of the upper end of the cylinder body 2, and is engaged with the middle of the support plate 4. Figure 1 and Figure 3 As shown, the cylinder body 2 drives the support rod 3 to engage in the middle of the support plate 4, and then the fixing block 5 is inserted into the middle of the support rod 3. At the same time, the fixing block 5 is attached to the upper end of the support plate 4. Then, the fixing block 5 and the support plate 4 are limited by the fastening bolt 6, so that the cylinder body 2 can be connected and fixed very quickly and conveniently.

[0034] Example 2: To address the problems existing in the prior art, this example provides a high-pressure hydraulic cylinder capable of rapid docking and fixing, equipped with a reinforcing mechanism 7. The reinforcing mechanism 7 is symmetrically arranged at both ends of the cylinder body 2, and provides auxiliary support for the cylinder body 2. The reinforcing mechanism 7 includes support columns 8 hinged to the lower left and right sides of the mounting plate 1, an auxiliary plate 9 hinged to the lower end of the support columns 8, a connecting rod 10 fixedly connected to the outer side of the cylinder body 2, and a connecting cap 11 for locking and limiting. The support columns 8 drive the auxiliary plate 9 to form a flipping structure at the lower end of the mounting plate 1. The auxiliary plates 9 are respectively fitted to the left and right ends of the cylinder body 2. The auxiliary plates 9 are engaged with the connecting rod 10, and the outer surface of the connecting rod 10 is threaded with the connecting cap 11. The connecting cap 11 is tightly fitted to the outer side of the auxiliary plate 9. Figure 2 , Figure 4 and Figure 5 As shown, by flipping the support column 8, the support column 8 rotates at the lower end of the mounting plate 1, and the support column 8 rotates with the auxiliary plate 9. The support column 8 drives the auxiliary plate 9 to fit against the left and right sides of the cylinder body 2 respectively. At the same time, the connecting rod 10 is engaged in the middle of the auxiliary plate 9. Then, the connecting cap 11 threaded to the outer surface of the connecting rod 10 is rotated, so that the connecting cap 11 fits against the outer side of the auxiliary plate 9, thereby facilitating the limiting of the auxiliary plate 9 and the connecting rod 10. With the setting of the reinforcement mechanism 7, it is convenient to provide auxiliary support and reinforcement for the cylinder body 2, thereby greatly improving the stability of the high-pressure cylinder in use.

[0035] Example 3: To address the problem of poor buffering effect caused by friction between the piston plate 13 and the inner wall of the cylinder body 2 in the prior art, this example provides a high-pressure cylinder capable of quick docking and fixing. The cylinder includes a connection port 12, a piston plate 13, a piston rod 14, a movable plate 15, a buffer cylinder 16, a buffer rod 17, and a buffer spring 18. The upper end of the cylinder body 2 has the connection port 12, and the bottom of the cylinder body 2 and the piston rod 14 form a sliding structure. The piston rod 14 drives the movable plate 15 to move up and down at the lower end of the cylinder body 2. The buffer spring 18 is installed in the inner cavity of the buffer cylinder 16, and the movable end of the buffer spring 18 is fixedly connected to the buffer rod 17. The buffer rod 17 is telescopically connected to the middle of the buffer cylinder 16, and the buffer cylinder 16 is fixed at an equal angle to the bottom of the cylinder body 2. Figure 1 , Figure 6 , Figure 7 and Figure 8As shown, in actual use, the piston plate 13 extends and retracts inside the cylinder body 2. The piston plate 13 pushes the piston rod 14 to slide at the bottom of the cylinder body 2, causing the movable plate 15 to move up and down at the lower end of the cylinder body 2. During the movement, the piston plate 13 presses the buffer rod 17, causing the buffer rod 17 and the buffer cylinder 16 to slide and retract. The buffer rod 17 presses the buffer spring 18, causing the buffer spring 18 to undergo elastic deformation, thereby providing good buffer protection for the piston plate 13 and preventing the piston plate 13 from violently colliding in the cylinder body 2 under high pressure.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
