Description

Technical Field

[0001] The utility model relates to the technical field of coal mine comprehensive machine accessories, and more specifically to a high-stability joint seat for coal mine comprehensive machine accessories. Background Art

[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. A variety of machines are used in the mining process. Among them, mining joints are used when connecting the high-pressure hoses in hydraulic machinery. The structural strength of the joints directly affects the stability of the hoses during connection. For this reason, a joint with high structural strength and stability is required for coal mine comprehensive machine accessories.

[0003] During the installation and use of the existing joint seats for coal mine comprehensive machine accessories, the internal pressure of the hydraulic pipeline in the hydraulic machinery is relatively high. Under the influence of pressure, the connection between the hydraulic pipeline and the joint seat is easily disconnected after a period of use. The stability of the joint seat during use is relatively general, causing inconvenience to the operation of the machinery. For this reason, we propose a joint seat with high structural strength and stability for coal mine comprehensive machine accessories to solve the existing problems. Utility Model Content

[0021] Reference Figure 1-Figure 5 The utility model provides a high-stability joint seat for coal mine comprehensive machine accessories, including a fixed pipe 1 and a fixed component 3. The inner side of the fixed pipe 1 is fixedly connected with a connecting pipe 101, the top of the fixed pipe 1 is fixedly connected with a fixed frame 2, elastic components 304 are installed around the bottom of the inner wall of the fixed component 3, a fixing ring 305 is installed at the bottom of the elastic component 304, a conical pipe 306 is fixedly connected to the inner side of the fixing ring 305, and internal threads 307 are arranged around the inner wall of the fixed component 3.

[0022] In the embodiment of the present application, when the external hose needs to be connected, the hose is inserted into the inner side of the fixing component 3 and sleeved on the outer side of the connecting pipe 101. The fixing component 3 can be fixed to the outer side of the fixing frame 2 through the meshing action of the inner thread 307 and the outer thread 201, and the tapered tube 306 is inserted into the inner side of the inclined groove 202. During the process of inserting the tapered tube 306 into the inner side of the inclined groove 202, the tapered tube 306 is squeezed by the inclined groove 202, and the pressure of the tapered tube 306 on the outer side of the hose gradually increases, so that the hose can be firmly fixed on the outer side of the connecting pipe 101, thereby improving the stability of the connection and preventing it from falling off during use.

[0023] In the process of threading the fixing component 3 onto the outside of the fixing frame 2, the pressure spring 343 is gradually compressed, and the multiple pressure springs 343 can generate a large thrust on the fixing ring 305 and the top of the inner wall of the fixing component 3, thereby further enabling the tapered tube 306 to be more stably inserted into the inner side of the bevel groove 202 to fix the hose, and can increase the extrusion force and friction force of the threaded surface of the internal thread 307 and the external thread 201, so that the fixing component 3 and the fixing frame 2 are not easy to rotate relative to each other.

[0024] In a preferred embodiment, the bottom of the fixed tube 1 is fixedly connected to a bottom frame 4, and circular holes 401 are opened on both sides of the bottom frame 4. The bottom frame 4 and the circular holes 401 are commonly used mechanisms in the prior art and will not be described in detail in this application.

A bevel groove 202 is provided on the inner side of the outer thread 201. The bevel groove 202 is a cone with a top diameter larger than a bottom diameter. The outer side of the conical tube 306 is a bevel with a top diameter larger than a bottom diameter. The conical tube 306 and the bevel groove 202 are adapted to each other. During the process of inserting the conical tube 306 into the inner side of the bevel groove 202, the pressure of the conical tube 306 on the outside of the hose gradually increases.

[0026] In a preferred embodiment, a polygonal edge block 301 is fixedly connected to the top of the outer side of the fixing component 3, a handle rod 302 is fixedly connected to the middle of the outer side of the fixing component 3, and a fixing ball 303 is fixedly connected to the end of the handle rod 302 away from the fixing component 3. Auxiliary tools are used to facilitate fixing the fixing component 3 through the polygonal edge block 301. When there are no auxiliary tools, the fixing component 3 can be fixed by holding the handle rod 302 and rotating it.

[0027] In a preferred embodiment, the elastic component 304 includes a fixed rod 341 fixedly connected to the top of the inner wall of the fixed component 3, and the bottom of the outer side of the fixed rod 341 is movably sleeved with a cylindrical tube 342, the bottom of the cylindrical tube 342 is fixedly connected to the top of the fixed ring 305, and a pressure spring 343 is arranged on the outer side of the cylindrical tube 342, and the pressure spring 343 is located between the top of the fixed ring 305 and the top of the inner wall of the fixed component 3. After being compressed, the pressure spring 343 stores a large elastic potential energy, generates a large thrust on the fixed ring 305, and generates a large thrust on the top of the inner wall of the fixed component 3.

[0028] The working principle of the utility model is as follows: when the external hose needs to be connected, the hose is inserted into the inner side of the fixing component 3 and sleeved on the outer side of the connecting pipe 101. The fixing component 3 can be fixed to the outer side of the fixing frame 2 through the meshing action of the inner thread 307 and the outer thread 201, and the tapered tube 306 is inserted into the inner side of the inclined groove 202. During the process of inserting the tapered tube 306 into the inner side of the inclined groove 202, it is squeezed by the inclined groove 202, and the pressure of the tapered tube 306 on the outer side of the hose gradually increases, so that the hose can be firmly fixed on the outer side of the connecting pipe 101, thereby improving the stability of the connection and avoiding falling off during use;

[0029] In the process of threading the fixing component 3 onto the outside of the fixing frame 2, the pressure spring 343 is gradually compressed, and the multiple pressure springs 343 can generate a large thrust on the fixing ring 305 and the top of the inner wall of the fixing component 3, thereby further enabling the tapered tube 306 to be more stably inserted into the inner side of the bevel groove 202 to fix the hose, and can increase the extrusion force and friction force of the threaded surface of the internal thread 307 and the external thread 201, so that the fixing component 3 and the fixing frame 2 are not easy to rotate relative to each other.
