Detailed Implementation

[0023] 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. It should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection", and "setting" should be interpreted broadly. For those skilled in the art, the specific meaning of the above terms in this patent can be understood according to the specific circumstances.

[0024] Reference Figure 1-Figure 4 A hydraulic cylinder with positioning adjustment includes a mounting plate 1, support blocks 2 fixedly mounted on both sides of the back of the mounting plate 1, movable blocks 3 slidably connected to both sides of the surface of the mounting plate 1, mounting grooves opened on the surface of the movable blocks 3, hydraulic cylinders 4 disposed inside the mounting grooves, positioning plates 5 fixedly mounted on both sides of the surface of the movable blocks 3, positioning components 6 fixedly mounted on both sides of the surface of the positioning plates 5, guide tubes 7 disposed on both sides of the surface of the hydraulic cylinder 4, and sealing components 8 disposed inside the guide tubes 7.

[0025] Connecting grooves are provided at the four corners of the surface of the mounting plate 1. The internal threads of the connecting grooves are connected to positioning bolts. The positioning bolts facilitate the installation of the mounting plate 1 by personnel and reduce the efficiency of the installation of the mounting plate 1.

[0026] The surface of the guide tube 7 is provided with a rotating groove, and a control valve 9 is rotatably connected inside the rotating groove. The control valve 9 can control the guide tube 7, thereby improving the efficiency of oil inlet flow rate and closure.

[0027] The hydraulic cylinder 4 includes a cylinder barrel and cylinder head, a piston and piston rod, a sealing device, a buffer device and an exhaust device. The piston and plunger inside the hydraulic cylinder 4 reciprocate.

[0028] The positioning component 6 includes a limiting plate 61 fixedly installed on both sides of the surface of the positioning plate 5. A threaded groove is provided in the middle of the surface of the limiting plate 61. A threaded rod 62 is threadedly connected inside the threaded groove. A clamping plate 63 is rotatably connected to one end of the threaded rod 62. A positioning block 64 is provided on the surface of the clamping plate 63. Positioning grooves are provided on both sides of the surface of the mounting plate 1. The size of the positioning groove is adapted to the size of the positioning block 64. The positioning block 64 is snapped into the inside of the positioning groove.

[0029] During use, the operator places the hydraulic cylinder 4 on the surface of the mounting plate 3, and then rotates the threaded rod 62 by the limiting plate 61 on the moving block 3. When the threaded rod 62 rotates, it will drive the clamping plate 63 to move. When the clamping plate 63 moves, it will drive the positioning block 64 to move forward. The positioning block 64 installs the mounting plate 1.

[0030] The sealing assembly 8 includes a sealing cap 81 threadedly connected inside the guide tube 7. A telescopic rod 82 is fixedly installed at each of the four corners of one end of the sealing cap 81. A spring 83 is sleeved on the surface of the telescopic rod 82. A sealing plate 84 is fixedly installed at one end of the telescopic rod 82. A rubber ring 85 is provided at the edge of the surface of the sealing plate 84. Limit grooves are opened on both sides of the surface of the sealing cap 81. An anti-slip pad to improve anti-slip properties is embedded inside the limit groove.

[0031] After the hydraulic cylinder 4 is filled with oil, the sealing cover 81 is rotated through the guide tube 7. When the sealing cover 81 rotates, it will drive the telescopic rod 82 and spring 83 at one end of the sealing cover 81 to move. After the sealing plate 84 at one end of the telescopic rod 82 is squeezed, it will rebound through the telescopic rod 82 and spring 83. During the rebound process, the rubber ring 85 on the sealing plate 84 will seal the guide tube 7.

[0032] Working principle: When the hydraulic cylinder 4 needs to be installed, the hydraulic cylinder 4 is placed on the surface of the mounting plate 3. Then, the threaded rod 62 is rotated by the limiting plate 61 on the moving block 3. When the threaded rod 62 rotates, it will drive the clamping plate 63 to move. When the clamping plate 63 moves, it will drive the positioning block 64 to move forward. The positioning block 64 installs the mounting plate 1. Then, the sealing cover 81 is rotated by the guide tube 7. When the sealing cover 81 rotates, it will drive the telescopic rod 82 and spring 83 at one end of the sealing cover 81 to move. After the sealing plate 84 at one end of the telescopic rod 82 is squeezed, it will rebound through the telescopic rod 82 and spring 83. During the rebound process, the rubber ring 85 on the sealing plate 84 will seal the guide tube 7.

[0033] In this application, the structures and connections not described in detail are all prior art, and their structures and principles are well known, so they will not be described again here.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
