[0002] At present, in the solenoid valve pneumatic industry, the connection method used by the solenoid valve is to directly connect the air pipe and the solenoid valve interface to achieve the purpose of inflating the air bag. This kind of air pipe and solenoid valve plug-in connection will result in cumbersome plug-in, complicated procedures, and difficult plug-in problems, which will reduce production speed and waste manpower. Therefore, a simple and quick solenoid valve plug-in device has appeared in the solenoid valve pneumatic industry.

[0003] A plug-in pneumatic solenoid valve is disclosed in the utility model patent with the patent authorization announcement number CN210566565U, including a solenoid valve body, a fixing ring and a box body, both sides of the solenoid valve body are fixedly installed with connecting pipes, the bottom of the solenoid valve body is fixedly installed with a connecting platform, and the outer periphery of the solenoid valve body on the top of the connecting platform is fixedly installed with a fixing ring, the bottom of the connecting platform is fixedly installed with a box body, the surface of the box body is rotatably installed with a protective door through a hinge, the surface of the protective door is fixedly installed with an indicator light, one side of the protective door is fixedly installed with a buckle, and one side of the buckle is rotatably installed with a connecting bolt, the bottom of the box body is provided with a wiring window, and the inside of the box body is fixedly installed with a battery pack. The utility model is provided with a series of structures to make the device easy to install and disassemble during use, and can make it more convenient for users to judge the operating status of the device and have the advantages of backup power supply, thereby optimizing the use process.

[0004] However, the existing solenoid valve plug-in device also has certain shortcomings. First, when the existing solenoid valve plug-in device is plugged into the trachea body for quick connection, due to the problem of gap, the solenoid valve plug-in sealing is weak;

[0005] Secondly, the existing solenoid valve plug-in devices mostly use straight-through plugs to circulate gas through the air pipe body. Due to the influence of external factors such as air pressure, it is easy to cause gas reflux after inflation is completed. Summary of the invention

[0006] The utility model aims to provide a simple and quick electromagnetic valve plug-in device, which solves the problem that the electromagnetic valve plug-in sealing is weak due to the gap problem when the existing electromagnetic valve plug-in device is plugged into the trachea body for quick connection; and solves the problem that the existing electromagnetic valve plug-in device mostly uses a straight-through plug to circulate gas through the trachea body, which is easy to cause gas reflux due to the influence of external factors such as air pressure.

[0007] In order to achieve the above-mentioned purpose, the utility model provides a simple and quick solenoid valve plug-in device, including a solenoid valve body, a support is arranged on the outside of the solenoid valve body, a plug is arranged on the right end of the solenoid valve body, a trachea body is slidably sleeved on the outside of the plug, a plug-in limit ring is arranged on the outside of the plug, the plug-in limit ring is in contact with the trachea body, and an anti-backflow mechanism is arranged inside the plug.

[0008] The principle of the utility model is that by pushing the air pipe body to be sleeved on the outer side of the plug of the electromagnetic valve body, the electromagnetic valve body and the air pipe body can be quickly plugged in and used under the action of the plug-in limit ring. In this process, under the extrusion of the port of the air pipe body, the seal moves to push the guide block to slide along the inner wall of the plug, and finally the seal contacts the plug, and the arc surface of the seal contacts the inner wall of the air pipe body. Under the deformation action of the spring, the seal can be pushed to always be in close contact with the air pipe body to ensure the plug-in sealing of the plug.

[0009] The air bag can be inflated by setting the solenoid valve body, the plug and the air pipe body. During this process, the plug moves under the impact of the gas to push the top plate to move, and the spring 2 is deformed, which eventually causes the plug to separate from the fixed disk and put the plug in a flow state. When the inflation is completed, the spring 2 restores its deformation to push the plug to the left, and then pushes the plug into the fixed disk to seal the plug and avoid the problem of gas reflux.

[0010] The beneficial effect of the utility model is that: this scheme pushes the trachea body to be sleeved on the solenoid valve body, and under the action of the plug-in limit ring, the plug of the solenoid valve body can be quickly plugged in and used, and under the deformation action of spring one and the extrusion of the port of the trachea body, the seal can be moved, so that the seal is always in contact with the inside of the trachea body to ensure the plug-in sealing of the solenoid valve body, and the air bag can be inflated through the arrangement of the solenoid valve body and the trachea body, and when the inflation is stopped, the plug can be pushed to reset under the deformation action of spring two, and then the plug can be sealed to avoid the problem of gas reflux.

[0011] Furthermore, the inner wall of the trachea body is in contact with four seals arranged in a circular array, and two adjacent seals are in contact with each other. The end face of each seal away from the trachea body is fixedly connected to a guide block, and the guide block is slidably connected to the plug. A spring 1 is welded to the end face of the guide block away from the seal, and the other end of the spring 1 is welded to the plug. By pushing the trachea body to be sleeved on the outside of the plug of the solenoid valve body, the solenoid valve body and the trachea body can be quickly plugged in under the action of the plug-in limit ring. In this process, under the extrusion of the trachea body port, the seal moves to push the guide block to slide along the inner wall of the plug, and finally makes the seal contact with the plug, and makes the arc surface of the seal contact with the inner wall of the trachea body. Under the deformation action of spring 1, the seal can be pushed to always be in close contact with the trachea body to ensure the plug-in sealing of the plug.

[0012] Furthermore, the seal is fan-shaped as a whole and is made of wear-resistant rubber material. Through the arrangement of the seal, the plug-in sealing performance of the solenoid valve body can be improved.

[0013] Furthermore, the guide block is in a rectangular shape as a whole and is made of cast iron. The seal can be guided by the rectangular setting of the guide block, and the cast iron material has good wear resistance.

[0014] Furthermore, the anti-backflow mechanism includes a fixed disk, the inner wall of the plug is fixedly connected to the fixed disk, the inner wall of the fixed disk is slidably connected to the plug, the inner wall of the plug and the right side of the fixed disk is fixedly connected to a fixed rod, the surface of the fixed rod is provided with a circulation hole, the inside of the fixed rod is slidably connected to a top plate, the top plate is fixedly connected to the plug, and a spring 2 is provided on the outer side of the top plate. The air bag can be inflated by the arrangement of the solenoid valve body, the plug and the trachea body. During this process, the plug moves under the impact of the gas to push the top plate to move, and the spring 2 is deformed, which eventually causes the plug to detach from the fixed disk, so that the plug is in a circulation state. When the inflation is completed, the spring 2 restores the deformation to push the plug to move to the left, and then pushes the plug to insert into the fixed disk to seal the plug and avoid the problem of gas backflow.

[0015] Furthermore, two circulation holes are provided, and the two circulation holes are symmetrically distributed on the fixing rod. The provision of the circulation holes can improve the circulation effect of the airflow.

[0016] Furthermore, one end of the second spring is welded to the fixing rod, and the other end of the second spring is fixedly connected to the plug. Through the arrangement of the second spring, the plug can be tightened for use. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the present embodiment provides a simple and quick solenoid valve plug-in device, comprising a solenoid valve body 1, a support 2 is arranged on the outer side of the solenoid valve body 1, a plug 3 is arranged on the right end of the solenoid valve body 1, a trachea body 4 is slidably sleeved on the outer side of the plug 3, a plug-in limiting ring 5 is arranged on the outer side of the plug 3, the plug-in limiting ring 5 is in contact with the trachea body 4, and the inner wall of the trachea body 4 is in contact with four sealing members 6 arranged in a ring array, the sealing member 6 is fan-shaped as a whole, and the sealing member 6 is made of wear-resistant rubber material. Through the setting of the sealing member 6, the plug-in sealing performance of the solenoid valve body 1 can be improved, and two adjacent sealing members 6 are in contact with each other. The end face of each sealing member 6 away from the trachea body 4 is fixedly connected with a guide block 7, and the guide block 7 is slidably connected to the plug 3. The guide block 7 is rectangular as a whole, and the guide block 7 is made of cast iron. The rectangular setting of the guide block 7 can guide the seal 6, and the cast iron material has good wear resistance. A spring 8 is welded on the end face of the guide block 7 away from the seal 6, and the other end of the spring 8 is welded to the plug 3. By pushing the trachea body 4 to be sleeved on the outside of the plug 3 of the solenoid valve body 1, under the action of the plug-in limit ring 5, the solenoid valve body 1 and the trachea body 4 can be quickly plugged in. During this process, under the extrusion of the port of the trachea body 4, the seal 6 moves to push the guide block 7 to slide along the inner wall of the plug 3, and finally makes the seal 6 contact with the plug 3, and makes the arc surface of the seal 6 contact with the inner wall of the trachea body 4. Under the deformation action of the spring 8, the seal 6 can be pushed to always be in close contact with the trachea body 4 to ensure the plug-in sealing of the plug 3.

[0025] like Figure 1 , Figure 2 , Figure 5As shown, the plug 3 is provided with an anti-backflow mechanism 9 inside, and the anti-backflow mechanism 9 includes a fixed disk 91, the inner wall of the plug 3 is fixedly connected with the fixed disk 91, the inner wall of the fixed disk 91 is slidably connected with a plug 92, the inner wall of the plug 3 and the right side of the fixed disk 91 is fixedly connected with a fixed rod 93, the surface of the fixed rod 93 is provided with a flow hole 94, and two flow holes 94 are provided, and the two flow holes 94 are symmetrically distributed on the fixed rod 93. The flow hole 94 can improve the flow effect of the airflow, and the fixed rod 93 is slidably connected with a top plate 95 inside the fixed rod 93, and the top plate 95 is fixedly connected with the plug 92, and the outer side of the top plate 95 is provided with a spring 96, and one end of the spring 96 Welded with the fixing rod 93, the other end of the spring 96 is fixedly connected to the plug 92. Through the setting of the spring 96, the plug 92 can be tightened for use. Through the setting of the solenoid valve body 1, the plug 3, and the trachea body 4, the air bag can be inflated. During this process, the plug 92 moves under the impact of the gas to push the top plate 95 to move, and the spring 96 is deformed, which eventually causes the plug 92 to separate from the fixed disk 91, so that the plug 3 is in a circulation state. When the inflation is completed, the spring 96 resumes its deformation to push the plug 92 to move to the left, and then pushes the plug 92 to insert into the fixed disk 91, thereby sealing the plug 3 and avoiding the problem of gas reflux.

During this process, the plug 92 moves under the impact of the gas to push the top plate 95 to move, and the spring 2 96 is deformed, and finally the plug 92 is separated from the fixed disk 91, so that the plug 3 is in a flow state. When the inflation is completed, the spring 2 96 restores the deformation to push the plug 92 to move to the left, and then pushes the plug 92 to insert into the fixed disk 91, thereby blocking the plug 3 and avoiding the problem of gas reflux.

[0028] This solution pushes the trachea body 4 to be sleeved on the solenoid valve body 1. Under the action of the plug-in limit ring 5, the plug 3 of the solenoid valve body 1 can be quickly plugged in and used. Under the deformation action of the spring 1 8 and the extrusion of the port of the trachea body 4, the seal 6 can be moved, so that the seal 6 is always in contact with the inside of the trachea body 4 to ensure the plug-in sealing of the plug 3 of the solenoid valve body 1.
