[0027] Please see Figures 1-4This utility model provides a technical solution: a novel pneumatic quick connector, including an outer cylinder 1, a first connector 2 fixedly connected to the inner wall above the outer cylinder 1, a movable groove 9 opened on the outer wall of the outer cylinder 1, a threaded ring 8 slidably installed on the outer wall of the outer cylinder 1 located inside the movable groove 9, a second connector 5 threadedly installed on the inner wall of the threaded ring 8, a fixing block 12 fixedly connected to the inner wall of the outer cylinder 1, the upper side of the fixing block 12 being inverted conical, a stop ring 15 installed at the upper end of the second connector 5, a vent block 13 abutting at the upper end of the stop ring 15, an air inlet hole opened at the lower end of the vent block 13, multiple sets of vent holes 14 opened on the outer wall around the vent block 13, a conical block 11 installed at the upper end of the vent block 13, a reset mechanism provided at the upper end of the conical block 11, the reset mechanism including a spring 10, the spring 10 being fixedly connected to the conical block 11, and the side of the spring 10 away from the conical block 11 being fixedly connected to the inner wall of the first connector 2.

[0028] In the technical solution of this utility model, the threaded ring 8 can slide in the movable groove 9, and the threaded ring 8 can be threaded to the first connector 2 and the second connector 5. When the first connector 2 and the second connector 5 abut, the abutting ring 15 on the second connector 5 abuts the vent block 13 and the conical block 11 to move, so that the gas inside the first connector 2 and the second connector 5 can flow under the cooperation of the vent hole 14 and the air inlet on the vent block 13. By twisting the threaded ring 8, the distance between the vent hole 14 and the fixed block 12 can be adjusted, thereby adjusting the flow rate of the airflow. This connection method is more stable.

[0029] In addition, the spring 10 can be used to reset the conical block 11.

[0030] In the technical solution of this utility model, such as Figure 2 and Figure 3 As shown, the air inlet corresponds to the inner cavity of the abutment ring 15 and the inner cavity of the second connector 5. The correspondence between the air inlet and the inner cavity of the abutment ring 15 and the inner cavity of the second connector 5 facilitates the flow of gas. The abutment ring 15 is made of hard alloy. The surfaces of the vent block 13 and the conical block 11 are provided with silicone sleeves. The hard alloy material of the abutment ring 15 can play a sealing role, and the silicone sleeves on the surfaces of the vent block 13 and the conical block 11 can further play a sealing role.

[0031] In the technical solution of this utility model, such as Figure 2As shown, the outer wall of the first connector 2 is provided with a first threaded groove 3, and the outer wall of the first connector 2 above the first threaded groove 3 is fitted with a first sealing ring 4. The first threaded groove 3 enables the first connector 2 to be quickly installed with the pipe, while the first sealing ring 4 can seal the first connector 2 with the pipe. The outer wall of the second connector 5 is provided with a second threaded groove 7, and the outer wall of the second connector 5 below the second threaded groove 7 is fitted with a second sealing ring 6. The second threaded groove 7 enables the second connector 5 to be quickly installed with the pipe, while the second sealing ring 6 can seal the second connector 5 with the pipe.

[0032] In the technical solution of this utility model, such as Figure 1 As shown, the outer wall of the threaded ring 8 is fixedly connected with an anti-slip strip, which can prevent slipping when the staff uses the threaded ring 8.

[0033] In use, the first connector 2 is first fixed to the inner wall above the outer cylinder 1 for connection with external pipes or equipment. The threaded ring 8 is located in the movable groove 9 of the outer cylinder 1 and can slide freely. The second connector 5 is installed in the threaded ring 8 by threads, opposite to the first connector 2. The abutment ring 15 is installed at the upper end of the second connector 5 and abuts against the lower end of the vent block 13. The vent block 13 is located above the fixed block 12. The upper side of the fixed block 12 has an inverted conical design. The lower end of the vent block 13 has an air inlet hole and multiple sets of vent holes 14 around it. The conical block 11 is located at... Above the vent block 13, a reset mechanism spring 10 connects to the inner wall of the first connector 2, ensuring that in the initial state, the conical block 11 is tightly fitted with the inner walls of the vent block 13 and the fixed block 12. When it is necessary to connect to an external pipe or equipment, the threaded ring 8 is rotated, causing the second connector 5 to move towards the first connector 2. As the second connector 5 moves, the abutment ring 15 pushes the vent block 13 upward, causing the vent block 13 to disengage from the inner wall of the fixed block 12. External gas passes through the first threaded groove 3 of the first connector 2 if it is connected to an external pipe or the second connector 5. If the second threaded groove 7 is connected to an external device, gas enters the inner cavity of the second connector 5 and connects to the air inlet at the lower end of the vent block 13 through the inner cavity of the abutment ring 15. When gas enters the vent block 13 through the air inlet, the gas pressure causes the vent block 13 to rise further. At the same time, gas flows out from the multiple sets of vent holes 14 around the vent block 13 and enters the sealing space between the first connector 2 and the second connector 5. Since the silicone sleeve between the vent block 13 and the conical block 11 has good elasticity and sealing performance, it can further ensure the reliability of the seal. When it is necessary to disconnect the connection, the threaded ring 8 is rotated to move the second connector 5 away from the first connector 2. The pressure between the abutment ring 15 and the vent block 13 decreases, and the vent block 13 moves downward under the action of the reset mechanism spring 10, restoring the tight fit with the fixed block 12. Through the above process, the new pneumatic quick connector can achieve rapid ventilation and reliable sealing during the connection process, and can also quickly discharge gas when disconnecting the connection, which is convenient for operation. At the same time, the use of silicone sleeve can further improve the sealing performance and ensure the stability and safety of the connector.
