Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinders, specifically a hydraulic cylinder cap for a multi-seal hydraulic cylinder. Background Technology

[0002] In the field of mechanical manufacturing, multi-seal hydraulic cylinders are widely used in various hydraulic systems to control and execute the movement of hydraulic equipment. A multi-seal hydraulic cylinder typically consists of a cylinder body, sealing components, a piston, and a piston rod. The cylinder cap, as a crucial component, primarily functions to fix and seal the cylinder body and protect the piston rod, ensuring the normal operation of the hydraulic system.

[0003] Existing cylinder caps are generally installed on the top of the cylinder with multiple bolts for sealing. When disassembling the cylinder cap, it is necessary to remove multiple bolts first and then pry the cylinder cap out, making the disassembly and assembly process of the cylinder cap very inconvenient.

[0004] Therefore, it is necessary to propose a cylinder cap for a multi-seal hydraulic cylinder. Utility Model Content

[0005] The purpose of this invention is to provide a cylinder cap for a multi-seal hydraulic cylinder to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cylinder cap for a multi-seal hydraulic cylinder includes a cylinder cap body, and a connecting mechanism is provided between the cylinder cap body and the top of the hydraulic cylinder. The connecting mechanism facilitates the assembly and disassembly of the cylinder cap for the multi-seal hydraulic cylinder.

[0008] The connecting mechanism includes a top plate and a plug ring. The top plate is fixedly installed on the top side wall of the cylinder cap body, and the plug ring is fixedly installed at the bottom of the top plate. The cylinder cap body is inserted into the top of the cylinder, and the plug ring is connected to the top of the cylinder.

[0009] Preferably, an annular slot is provided on the inner wall of the top of the cylinder, and a first sealing ring is provided in the slot. The insert ring is matched and inserted into the slot and contacts the first sealing ring.

[0010] Preferably, a hexagonal first socket is fixedly installed at the bottom of the top plate, and a hexagonal second socket is fixedly installed on the side wall of the top of the cylinder, with the first socket being inserted into the outside of the second socket.

[0011] Preferably, a sealing gasket is provided on the inner side of the first socket, and the upper end of the second socket is tightly fitted to the sealing gasket.

[0012] Preferably, both the first socket and the second socket have threaded grooves on their side walls, and threaded bolts are connected in the threaded grooves.

[0013] Preferably, the inner wall of the cylinder cap body is provided with multiple second sealing rings.

[0014] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0015] A connecting mechanism is provided on the cylinder cap. The first and second sockets facilitate quick guidance and installation of the cylinder cap. The top of the cylinder cap is provided with a top plate, which makes it easy to remove the cylinder cap with leverage. Moreover, there is no need to drill holes. Finally, it can be fixed by using a small number of bolts. This not only makes it easy to disassemble and assemble the cylinder cap, but also provides a good sealing effect.

[0024] like Figures 1-5 ;

[0025] A cylinder cap for a multi-seal hydraulic cylinder includes a cylinder cap body 1. A connecting mechanism 2 is provided between the cylinder cap body 1 and the top of the hydraulic cylinder. The connecting mechanism 2 facilitates the disassembly and assembly of the cylinder cap for the multi-seal hydraulic cylinder. The first socket 22 and the second socket facilitate the quick guidance and installation of the cylinder cap. The top of the cylinder cap is provided with a top plate 21, which makes it easy to remove the cylinder cap with leverage. Finally, it can be fixed by using a small number of bolts. Thus, it is not only convenient to disassemble and assemble the cylinder cap, but also has a good sealing effect.

[0026] The connecting mechanism 2 includes a top plate 21 and a retaining ring 23. The top plate 21 is fixedly installed on the top side wall of the cylinder cap body 1, facilitating upward lifting during disassembly of the cylinder cap body 1. The retaining ring 23 is fixedly installed at the bottom of the top plate 21. The cylinder cap body 1 is inserted into the top of the cylinder, and the retaining ring 23 is connected to the top of the cylinder. An annular slot 26 is provided on the inner wall of the top of the cylinder, and a first sealing ring 27 is provided in the slot 26. The retaining ring 23 is inserted into the slot 26 and contacts the first sealing ring 27, increasing the sealing at the connection between the cylinder cap body 1 and the cylinder. A hexagonal first socket 22 is fixedly installed at the bottom of the top plate 21, and a hexagonal second socket 22 is fixedly installed on the side wall of the top of the cylinder. When installing the cylinder cap body 1, the first socket 22 is inserted into the outside of the second socket 25 to position and install the cylinder cap body 1, which facilitates subsequent fixation. A sealing gasket 24 is provided on the inner side of the first socket 22, and the upper end of the second socket 25 is tightly fitted to the sealing gasket 24 to increase the sealing performance of the inner side of the first socket 22. Threaded grooves 28 are provided on the side walls of both the first socket 22 and the second socket 25. Bolts are connected to the threaded grooves 28. A small number of bolts are used to connect and fix the first socket 22 and the second socket 25, which not only facilitates the disassembly and assembly of the cylinder cap body 1, but also provides a good sealing effect. Multiple second sealing rings 29 are provided on the inner wall of the cylinder cap body 1.

[0027] The working principle of this utility model is as follows: When assembling the cylinder cap, the first socket 22 is inserted into the outside of the second socket 25, and the top plate 21 is pressed to the bottom. At this time, the upper end of the second socket 25 is tightly attached to the sealing gasket 24, and the insert ring 23 is inserted into the slot 26 and contacts the first sealing ring 27. The sealing performance of the connection between the cylinder cap and the cylinder is increased by the first sealing ring 27 and the sealing gasket 24 respectively. Finally, a small number of bolts are used to connect and fix the side walls of the first socket 22 and the second socket 25, which not only facilitates the disassembly and assembly of the cylinder cap, but also has a good sealing effect. When disassembling and assembling the cylinder cap, first remove the bolts on the side wall of the first socket 22, and then lift the top plate 21 upward. The top plate 21 drives the cylinder cap to move upward, the first socket 22 is disengaged from the second socket 25, and the insert ring 23 is disengaged from the slot 26, so that the cylinder cap is pulled out from the top of the cylinder, which facilitates the disassembly and assembly of the cylinder cap.

[0028] In summary, by setting a connecting mechanism on the cylinder cap, the first socket 22 and the second socket not only facilitate the quick guidance and installation of the cylinder cap, but also provide a top plate 21 on the top of the cylinder cap, making it easy to remove the cylinder cap with leverage. Moreover, there is no need to drill holes, and finally, it can be fixed by using a small number of bolts. Thus, it is not only convenient to disassemble and assemble the cylinder cap, but also has a good sealing effect.

[0029] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
