[0001] The utility model relates to the field of vacuum valves, in particular to a vacuum valve quick-change mechanism. Background Art

[0002] A vacuum valve is a device used to control the gas flow and pressure in a vacuum system. In a vacuum system, various components are connected or isolated by vacuum valves to control the flow of gas in the vacuum system so that the system can work properly. The vacuum valve can control and isolate the pipeline flowing through it, or change the position of a pipeline. Vacuum valves are usually used to control, limit and adjust pressure, as well as change the direction of flow.

[0003] The existing vacuum valves still have the following problems when in use: the existing safety valves are usually connected to the pipeline by screws, which makes it inconvenient to quickly install and disassemble the vacuum valve, making the entire installation and disassembly process cumbersome, affecting subsequent use.

[0004] Therefore, it is necessary to invent a vacuum valve quick-change mechanism to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a vacuum valve quick-change mechanism to solve the problem that the existing safety valve and the pipeline are usually connected by screws as mentioned in the above background technology, which leads to inconvenience in operation when the vacuum valve needs to be quickly installed and disassembled, making the entire installation and disassembly process more cumbersome and affecting subsequent use.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vacuum valve quick-change mechanism, comprising a valve body, quick-connect pipes are movably installed on both sides of the valve body, mounting rings are fixedly connected to both sides of the valve body, the mounting rings are sleeved on the outer ring of the quick-connect pipes, and the top and bottom of the mounting rings are fixedly connected with protrusions, and the protrusions are rotatably connected to the abutment plate through a rotating shaft, and the outer wall of the abutment plate is fixedly connected with a shift block, and also includes:

[0007] A limiting component, wherein the outer ring of the mounting ring is movably sleeved with an annular block, and the inner wall of the annular block is fixedly connected with a moving block, and the moving block is slidably connected to the moving groove through a spring, the moving groove is located inside the mounting ring, and the side wall of the annular block is fixedly connected with a plug-in block, and the plug-in block passes through a notch reserved inside the protrusion and matches the plug-in groove reserved inside the rotating shaft.

[0008] Preferably, a sealing rubber ring is fixedly connected to the outer ring of the end of the quick-connect pipe, and the sealing rubber ring is installed in a fit with the inner wall of the mounting ring to ensure the tightness of the installation of the entire quick-connect pipe and the valve body, which will not affect subsequent use.

[0009] Preferably, the rotating shaft passes through the interior of the protrusion, and the rotating shaft and the reserved through-hole inside the protrusion are rotatably connected via a bearing, and both ends of the rotating shaft extend to the outside of the protrusion to ensure the stability of subsequent rotation of the rotating shaft.

[0010] Preferably, a torsion spring is movably sleeved on the outer ring of the rotating shaft, and one end of the torsion spring is fixedly connected to the side wall of the abutment plate, and the other end of the torsion spring is fixedly connected to the side wall of the protrusion, so that the force of the torsion spring causes the abutment plate to fit with the end of the quick-release tube in the initial state.

[0011] Preferably, the annular inner wall of the annular block is in contact with and slidably connected to the annular outer wall of the mounting ring, thereby ensuring the stability of the movement of the annular block.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] The utility model drives the plug-in block to move away from the plug-in groove and the notch by shifting the annular block, so that it is convenient to shift the shift block to adjust the abutment plate to rotate, so that the abutment plate is separated from the end of the quick-connect pipe, which is convenient to remove the quick-connect pipe. At the same time, when the quick-connect pipe is installed, the torsion spring on the outer ring of the rotating shaft applies force to make the abutment plate move and fit the end of the quick-connect pipe. At this time, the movement of the rotating shaft makes the plug-in groove and the notch be at the same horizontal position. In this way, the spring force causes the plug-in block to move and match the plug-in groove, thereby ensuring the stability of the installation of the valve body and the quick-connect pipe, thus ensuring the quickness of the installation.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model provides Figure 1-6 The vacuum valve quick-change mechanism shown includes a valve body 1, quick-change pipes 2 are movably installed on both sides of the valve body 1, mounting rings 3 are fixedly connected to both sides of the valve body 1, the mounting rings 3 are sleeved on the outer ring of the quick-change pipe 2, and the top and bottom of the mounting ring 3 are fixedly connected with protrusions 4, and the protrusions 4 are rotatably connected to the abutment plate 6 through the rotating shaft 5, and the outer wall of the abutment plate 6 is fixedly connected with a shifting block 7, and also includes:

[0027] The limiting assembly 8, the outer ring of the mounting ring 3 is movably sleeved with an annular block 81, and the inner wall of the annular block 81 is fixedly connected with a moving block 82, and the moving block 82 is slidably connected with the moving groove 83 through a spring 84, the moving groove 83 is located inside the mounting ring 3, and the side wall of the annular block 81 is fixedly connected with a plug-in block 85, and the plug-in block 85 passes through the notch 86 reserved inside the protrusion 4 and matches the plug-in groove 87 reserved inside the rotating shaft 5.

[0028] The outer ring of the end of the quick-connect pipe 2 is fixedly connected with a sealing rubber ring 21, and the sealing rubber ring 21 is installed in close contact with the inner wall of the mounting ring 3 to ensure the tightness of the installation of the entire quick-connect pipe 2 and the valve body 1, which will not affect the subsequent use.

[0029] The rotating shaft 5 passes through the inside of the protrusion 4, and the rotating shaft 5 is rotatably connected to the reserved through-hole inside the protrusion 4 through a bearing, and both ends of the rotating shaft 5 extend to the outside of the protrusion 4 to ensure the stability of the subsequent rotation of the rotating shaft 5.

[0030] A torsion spring is movably sleeved on the outer ring of the rotating shaft 5, and one end of the torsion spring is fixedly connected to the side wall of the abutment plate 6, and the other end of the torsion spring is fixedly connected to the side wall of the protrusion 4, so that the force of the torsion spring causes the abutment plate 6 to fit with the end of the quick-release tube 2 in the initial state.

[0031] The annular inner wall of the annular block 81 is in contact with and slidably connected to the annular outer wall of the mounting ring 3 , thereby ensuring the stability of the movement of the annular block 81 .

[0032] The side wall of the moving block 82 is in contact with and slidably connected to the inner wall of the moving groove 83, ensuring that the annular block 81 will not be misaligned during the subsequent movement process.

[0033] The spring 84 is located inside the movable groove 83, and one end of the spring 84 is fixedly connected to the inner wall of the movable groove 83, and the other end of the spring 84 is fixedly connected to the side wall of the movable block 82. Under the thrust of the spring 84, the plug-in block 85 is matched with the plug-in groove 87, thereby limiting the subsequent movement of the entire abutment plate 6.

[0034] Working principle: When using the vacuum valve quick-change mechanism, first, the annular block 81 is moved to drive the plug-in block 85 fixedly connected to the side wall of the annular block 81 to move and then leave the plug-in groove 87 reserved inside the rotating shaft 5 and the notch 86 reserved inside the protrusion 4. At this time, the rotating shaft 5 is not restricted by the plug-in block 85 and can rotate normally. At the same time, the dial block 7 is moved to mobilize the rotation of the abutment plate 6 that is rotatably connected to the protrusion 4 through the rotating shaft 5, so that the abutment plate 6 is separated from the outer wall of the end of the quick tube 2. The abutment plate 6 does not generate resistance to the quick tube 2, which makes it convenient to remove the quick tube 2;

[0035] At the same time, when the quick-connect pipe 2 needs to be installed, the outer ring torsion spring of the rotating shaft 5 applies force to make the abutment plate 6 rotate and fit with the end of the quick-connect pipe 2. At this time, the rotating shaft 5 moves synchronously so that the plug-in groove 87 reserved inside the rotating shaft 5 and the notch 86 reserved inside the protrusion 4 are at the same horizontal position and connected. In this way, the spring 84 applies force to prompt the plug-in block 85 to move and match the plug-in groove 87, thereby ensuring the stability of the installation of the valve body 1 and the quick-connect pipe 2 and making the installation faster. There is no need to use screws to adapt the valve body 1 and the quick-connect pipe 2 for installation. This saves installation and disassembly time, and there is no need to use other tools to adapt the valve body 1 and the quick-connect pipe 2 for installation, making the overall installation process more convenient.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
