Description

Technical Field

[0001] This utility model belongs to the field of hydraulic cylinder limit valves, and specifically relates to a novel multi-stage hydraulic cylinder limit valve mounting bracket. Background Technology

[0002] In existing technologies, installing limit valves on cylinders with limit valve brackets is difficult due to limited installation space. Traditional limit valve brackets have a simple structure, but their disadvantage is that one hand needs to be inside the bracket to secure the nut while the other hand is on the outside to install the bolt, making the operation difficult and cumbersome. Utility Model Content

[0003] The purpose of this invention is to provide a novel mounting bracket for a multi-stage hydraulic cylinder limit valve, which eliminates the need for operators to manually install the corresponding nuts, thereby improving installation efficiency and reducing operational safety hazards.

[0004] The purpose of this utility model is achieved as follows: A novel multi-stage hydraulic cylinder limit valve mounting bracket includes a cylindrical body, on which a support body is provided. The support body is U-shaped and has several rivet mounting nuts. Each rivet mounting nut extends toward the inner side of the support body. A limit valve is provided corresponding to the support body. The limit valve has several mounting holes that can accommodate several mounting bolts. Each mounting hole corresponds to a rivet mounting nut. Each mounting bolt passes through a mounting hole and is fixedly connected to the corresponding rivet mounting nut.

[0005] Compared with existing technologies, the advantages of this utility model are as follows: This limit valve mounting bracket consists of one bracket body and three riveted mounting nuts, eliminating the need for mounting nuts on the limit valve itself, thus reducing costs; when the limit valve is installed on the cylinder body, the operator does not need to reach inside the limit valve bracket to fix the nuts, improving work efficiency and reducing operational safety hazards. This riveted limit valve bracket can be widely used in multi-stage cylinders of various structures.

[0006] As a further improvement of this utility model, the bracket body includes a mounting panel, and side plates are vertically arranged on both the left and right sides of the mounting panel. Both side plates are fixedly connected to the cylinder body, and the rivet mounting nuts are located between the two side plates.

[0007] As a further improvement of this utility model, three rivet mounting nuts are provided, forming a triangle. Connecting the limit valve via these three rivet mounting nuts provides a more stable and secure connection.

[0008] As a further improvement of this utility model, the mounting panel of the bracket body has a through hole for the rivet mounting nut to pass through. The outer periphery of the rivet mounting nut is fixed to the inner wall of the through hole of the mounting panel. The rear end of the rivet mounting nut is provided with an annular outer step, which clamps the outer side of the mounting panel. The outer periphery of the rivet mounting nut is provided with an annular protrusion, which clamps the inner side of the mounting panel. The outer step and protrusion of the rivet mounting nut are used to position and fix it to the bracket body.

[0009] As a further improvement of this utility model, the inner wall of the rivet mounting nut is provided with an internal thread that matches the mounting bolt. The mounting bolt passes through the limit valve and is fixedly connected to the limit valve mounting bracket. The internal thread of the rivet mounting nut is an anti-loosening thread, which improves the reliability of the connection and extends the service life of the threaded connection structure.

[0017] like Figure 1-6 As shown, a novel multi-stage hydraulic cylinder limit valve mounting bracket includes a cylindrical body 1, on which a bracket body 2 is mounted. The bracket body 2 is U-shaped and has several rivet mounting nuts 3. Each rivet mounting nut 3 extends toward the cylindrical body 1 to the inner side of the bracket body 2. A limit valve 4 is provided corresponding to the bracket body 2. The limit valve 4 has several mounting holes 5 that can accommodate several mounting bolts 6. Each mounting hole 5 is provided corresponding to each rivet mounting nut 3. Each mounting bolt 6 passes through each mounting hole 5 and is fixedly connected to the corresponding rivet mounting nut 3.

[0018] The support body 2 includes a mounting panel 2a. Side plates 2b are vertically arranged on both the left and right sides of the mounting panel 2a. Both side plates 2b are fixedly connected to the cylinder 1. Rivet mounting nuts 3 are located between the two side plates 2b. Three rivet mounting nuts 3 are provided, forming a triangle. A limit valve 4 is connected via the three rivet mounting nuts 3 for greater stability and security. The mounting panel 2a of the support body 2 has a through hole 7 that allows the rivet mounting nuts 3 to pass through. The outer periphery of the rivet mounting nut 3 is fixed to the inner wall of the through hole 7 in the mounting panel 2a. An annular outer step 301 is provided at the rear end of the rivet mounting nut 3, which clamps onto the outer side of the mounting panel 2a. An annular rib 302 is provided on the outer periphery of the rivet mounting nut 3, which clamps onto the inner side of the mounting panel 2a. The outer step 301 and rib 302 of the rivet mounting nut 3 position it and fix it to the support body 2. The outer step 301 and rib 302 on the rivet mounting nut 3 are both produced by the riveting installation process. The inner wall of the rivet mounting nut 3 is provided with an internal thread 8 that matches the mounting bolt 6. The mounting bolt 6 passes through the limit valve 4 and is fixedly connected to the mounting bracket of the limit valve 4.

[0019] The advantages of this utility model are as follows: The limit valve 4 mounting bracket consists of one bracket body 2 and three rivet mounting nuts 3. The limit valve 4 does not require additional mounting nuts, reducing costs. When the limit valve 4 is installed on the cylinder body 1, the operator does not need to reach inside the limit valve 4 bracket to fix the nuts, improving work efficiency and reducing operational safety hazards. The internal thread of the rivet mounting nuts is an anti-loosening thread, improving connection reliability and extending the lifespan of the threaded connection structure. This riveted limit valve 4 bracket can be widely used in multi-stage cylinders of various structures.

[0020] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
