[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses a piston type cylinder.

[0026] The utility model provides Figure 1-4A piston cylinder shown in the figure comprises a mounting plate 1, a lower cylinder body 2 is arranged in the middle of the top of the mounting plate 1, an upper cylinder body 3 is butted against the top of the lower cylinder body 2, electric push rods 5 are fixed on both sides of the lower cylinder body 2, a block shell 7 is fixed to the push rod end of the electric push rod 5, a clamping block 11 is arranged on the inner side of the block shell 7, a locking groove 12 is provided on the inner side of the clamping block 11, locking plates 17 are fixed on both sides of the bottom end of the outer wall of the upper cylinder body 3, a cylinder groove 14 is provided inside the lower cylinder body 2 and a piston 18 is built in the cylinder groove 14, a cylinder rod 4 is fixed on the top of the piston 18 and the cylinder rod 4 passes through the top of the upper cylinder body 3, the piston cylinder is formed by butting the upper and lower cylinder bodies, when the internal piston 18 needs to be disassembled, replaced and repaired, the upper and lower cylinder bodies can be quickly separated and disassembled, which is conducive to taking out the piston 18, and will greatly improve the convenience of piston cylinder maintenance.

[0027] In order to quickly drive the upper and lower cylinders to lock and separate: Figure 1 and Figure 3 As shown, a pull rod 8 passes through the outer wall of the block 11, a pull handle 9 is fixed to the outer wall of the pull rod 8, the inner wall of the pull rod 8 is fixedly connected to the side wall of the block 11, and a spring 19 is sleeved on the outside of the pull rod 8. The spring 19 is located inside the block shell 7, one side of the spring 19 is in contact with the inner wall of the block 11, and the other end of the spring 19 is in contact with the inner wall of the block shell 7. The spring 19 will give the block 11 elasticity, thereby facilitating the driving of the block 11 to quickly connect and disassemble with the locking plate 17.

[0028] In order to lock the upper and lower cylinders: Figure 4 As shown, the card block 11 passes through the interior of the block shell 7, and the card block 11 and the block shell 7 form a sliding mechanism. The lock groove 12 is adapted to the size of the lock plate 17 for docking, and the lock groove 12 is wrapped around the outside of the lock plate 17. The card block 11 will slide based on the interior of the block shell 7, thereby ensuring the quick docking and separation effect of the card block 11 and the lock plate 17.

[0029] In order to ensure the stability of the upper and lower cylinders when locked: Figure 1 , Figure 2 and Figure 3 As shown, reinforcement blocks 6 are fixed on both sides of the outer wall of the lower cylinder body 2, the outer wall of the push rod of the electric push rod 5 passes through the inside of the reinforcement block 6, the four corners of the top of the mounting plate 1 are provided with fixing bolts 10, the four corners of the top of the lower cylinder body 2 are provided with docking holes 15, and the four corners of the bottom end of the upper cylinder body 3 are fixed with docking rods 16, the docking rods 16 are adapted to the size of the docking holes 15, and the docking rods 16 are inserted into the inside of the docking holes 15. In the process of docking the upper cylinder body 3 and the lower cylinder body 2, the docking rods 16 and the docking holes 15 are quickly limited and inserted, which is conducive to the rapid docking of the upper and lower cylinder bodies and at the same time strengthens the stability of the upper and lower cylinder bodies.

[0030] In order to ensure the airtightness of the cylinder body during use: Figure 2 As shown, the top of the lower cylinder body 2 is covered with a sealing gasket 13, and the lower cylinder body 2 is fitted and docked with the upper cylinder body 3 through the sealing gasket 13. The sealing gasket 13 is made of rubber material. When the upper and lower cylinder bodies are docked, the overall airtightness of the cylinder body will be guaranteed, and the normal operating efficiency of the cylinder will not be affected while ensuring quick disassembly.

[0031] During operation, the lower cylinder body 2 is docked with the upper cylinder body 3. When the lower cylinder body 2 and the upper cylinder body 3 need to be separated and disassembled, the pull handle 9 drives the card block 11 to move inside the block shell 7. At this time, the locking groove 12 in the driving card block 11 is separated from the locking plate 17. At this time, the lower cylinder body 2 and the upper cylinder body 3 are in an unlocked state. The upper cylinder body 3 is pulled up. At this time, the lower cylinder body 2 and the upper cylinder body 3 will be able to form a quick separation state, which will be convenient for disassembling the piston 18 in the upper cylinder body 3 for maintenance and replacement. When it is necessary to lock the lower cylinder body 2 and the upper cylinder body 3, the docking rod 16 at the bottom end of the upper cylinder body 3 is inserted into the docking hole 1 at the top end of the lower cylinder body 2 5, it will be conducive to the rapid docking of the lower cylinder body 2 and the upper cylinder body 3, and ensure the stability of the docking place between the lower cylinder body 2 and the upper cylinder body 3. A sealing gasket 13 is provided between the lower cylinder body 2 and the upper cylinder body 3 to ensure the air tightness of the docking installation. After the docking is completed, according to the above working principle, the pull handle 9 will drive the block 11 to move through the pull rod 8, so that the locking groove 12 in the block 11 is wrapped around the outside of the locking plate 17 to form a limit lock. Finally, the external control mechanism drives the electric push rod 5 to work, and the electric push rod 5 pulls down the drive block shell 7 to press the upper cylinder body 3 tightly against the top of the lower cylinder body 2. The design is simple and more practical.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
