Description

Technical Field

[0001] This utility model belongs to the field of grease injection valve technology, specifically, it relates to a grease injection valve connection device. Background Technology

[0002] Currently, various grease injectors and guns are generally connected to grease valves via high-pressure hoses. However, for some grease valves installed in confined spaces, the high internal pressure of the hose prevents it from bending, making connection between the valve and hose difficult, and sometimes impossible. Forcibly bending the hose can damage it, posing a safety hazard. Therefore, a grease valve connection device is urgently needed to solve the problem of difficult or impossible connection between grease valves installed in confined spaces and high-pressure hoses. Utility Model Content

[0003] One objective of this invention is to provide a grease injection valve connection device that allows for the connection and installation of a high-pressure hose and a grease injection valve by adjusting the angle between the second and first connecting pipes within a confined space, thereby reducing safety hazards.

[0004] According to the present invention, a grease injection valve connection device is provided, comprising: a first connecting pipe, a second connecting pipe, and a universal coupling, wherein a first end of the first connecting pipe is connected to a high-pressure hose, a first end of the second connecting pipe is connected to a grease injection valve, and a second end of the first connecting pipe is rotatably connected to the second end of the second connecting pipe through the universal coupling.

[0005] In a preferred embodiment, a pressure relief valve is provided on the first connecting pipeline.

[0006] In a preferred embodiment, the pressure relief valve is located on the side of the first connecting pipe near the outside of the installation space.

[0007] In a preferred embodiment, the angle between the first connecting pipe and the second connecting pipe is 135°.

[0008] In a preferred embodiment, the angle between the first connecting pipe and the second connecting pipe is 90°.

[0009] In a preferred embodiment, a pressure relief valve is provided on the second connecting pipeline.

[0010] In a preferred embodiment, a connecting screw is provided at the first end of the first connecting pipe, and the connecting screw is threadedly connected to a nut provided on the high-pressure hose.

[0011] In a preferred embodiment, a connecting nut is fitted onto the outer wall of the second end of the second connecting pipe, and the connecting nut is connected to the grease injection valve.

[0012] In a preferred embodiment, the first connecting pipe has a first external hexagonal portion on its outer wall, and the first external hexagonal portion is adjacent to the end of the connecting screw away from the high-pressure hose.

[0013] In a preferred embodiment, the grease injection valve connection device further includes a second external hexagonal portion disposed adjacent to the pressure relief valve.

[0014] This utility model has at least the following technical effects:

[0015] According to this utility model, a first connecting pipe, a second connecting pipe, and a universal coupling are provided. The first end of the first connecting pipe is connected to a high-pressure hose, and the first end of the second connecting pipe is connected to a grease injection valve. The second end of the first connecting pipe is rotatably connected to the second end of the second connecting pipe via the universal coupling. The universal coupling can be used to adjust the angle between the first and second connecting pipes to facilitate the installation of the injection pipe connected to the grease injection valve in confined spaces. Even when the grease injection valve is obstructed in a confined space, adjusting the angle between the second and first connecting pipes allows for the connection and installation of the high-pressure hose and the grease injection valve, reducing safety hazards.

[0016] After the high-pressure hose is connected and installed to the grease injection valve through the grease injection valve connection device described in this utility model, the pressure can be released after grease injection through the pressure relief valve, thereby effectively reducing safety hazards.

[0017] According to this utility model, the pressure relief valve is located on the side of the first connecting pipe close to the outside of the installation space, which can prevent the grease injection valve from being unable to be installed due to insufficient distance between the pressure relief valve and the equipment when the grease injection valve is installed in the installation space, thereby preventing the equipment from being unable to be greased.

[0023] like Figure 1 As shown, the grease injection valve connecting device 100 of this utility model is used to connect the grease injection valve (not shown in the figure) and the high-pressure hose (not shown in the figure) together. It includes: a first connecting pipe 1, a second connecting pipe 7 and a universal coupling 6. The first end of the first connecting pipe 1 is connected to the high-pressure hose, the first end of the second connecting pipe 7 is connected to the grease injection valve, and the second end of the first connecting pipe 1 is rotatably connected to the second end of the second connecting pipe 7 through the universal coupling 6.

The first end of the first connecting pipe 1 is connected to a high-pressure hose, the first end of the second connecting pipe 7 is connected to a grease injection valve, and the second end of the first connecting pipe 1 is rotatably connected to the second end of the second connecting pipe 7 via the universal coupling 6. The universal coupling 6 can be used to adjust the angle between the first connecting pipe 1 and the second connecting pipe 7 to facilitate the installation of the injection pipe connected to the grease injection valve in confined spaces. Even when the grease injection valve is obstructed in a confined space, adjusting the angle between the second connecting pipe 7 and the first connecting pipe 1 completes the connection and installation of the high-pressure hose and the grease injection valve, reducing safety hazards.

[0025] In one or more embodiments, a pressure relief valve 4 is provided on the first connecting pipe 1 for releasing pressure after grease injection.

[0026] If the high-pressure hose connecting the grease gun and the grease valve does not have a pressure relief function, the entire grease injection device poses a certain safety hazard. After connecting the high-pressure hose and the grease valve using the grease valve connection device 100 described in this utility model, the pressure relief valve 4 can release pressure after grease injection, thereby effectively reducing the safety hazard.

[0027] In one or more embodiments, the included angle between the first connecting pipe 1 and the second connecting pipe 7 ranges from 90° to 135°.

[0028] In one or more embodiments, the angle between the first connecting pipe 1 and the second connecting pipe 7 is 135°.

[0029] According to this utility model, the included angle between the first connecting pipe 1 and the second connecting pipe 7 is 135°, thereby making the first connecting pipe 1 and the second connecting pipe form a large angle bend, which facilitates the installation of the grease injection valve in a narrow space.

[0030] In one or more embodiments, the angle between the first connecting pipe 1 and the second connecting pipe 7 is 90°.

[0031] In one or more embodiments, the pressure relief valve 4 is disposed on the side of the first connecting pipe 1 near the outside of the installation space.

[0032] According to this utility model, the pressure relief valve 4 is located on the side of the first connecting pipe 1 near the outside of the installation space, which can prevent the grease injection valve from being unable to be installed due to insufficient distance between the pressure relief valve 4 and the equipment when the grease injection valve is installed in the installation space, thereby preventing the equipment from being unable to be greased.

[0033] In one or more embodiments, a pressure relief valve 4 is provided on the second connecting pipe 7.

[0034] In one or more embodiments, a connecting screw 3 is provided at the first end of the first connecting pipe 1, and the connecting screw 3 is threadedly connected to a nut provided on the high-pressure hose.

[0035] In one or more embodiments, a connecting nut 2 is fitted on the outer wall of the second end of the second connecting pipe 7, and the connecting nut 2 is connected to the grease injection valve.

[0036] In one or more embodiments, the first connecting pipe 1 is provided with a first external hexagonal portion 5 on its outer wall. The first external hexagonal portion 5 is adjacent to the end of the connecting screw 3 away from the high-pressure hose. When installing or removing the high-pressure hose, the first external hexagonal portion 5 is fixed by a wrench, and the high-pressure hose is installed or removed by screwing it, thereby facilitating the installation and removal of the high-pressure hose.

[0037] In one or more embodiments, the grease injection valve connection device 100 of the present invention further includes a second external hexagonal portion 8 disposed adjacent to the pressure relief valve 4. When installing or disassembling the pressure relief valve 4, the second external hexagonal portion 8 is fixed by a wrench, thereby facilitating the installation and disassembly of the pressure relief valve.

[0038] The installation, use, and disassembly process of the grease injection valve connecting device 100 described in this utility model is as follows: Adjust the included angle between the first connecting pipe 1 and the second connecting pipe 7, install the connecting nut 2 on the grease injection valve, and thread the connecting screw 3 to the nut of the high-pressure hose of the grease injection tool to achieve installation; close the pressure relief valve 4 and start grease injection, and open the pressure relief valve 4 to release pressure after grease injection is completed; disconnect the connecting screw 3 from the high-pressure hose, and then disconnect the connecting nut 2 from the grease injection valve.
