[0036] See also Figures 1 to 4As shown, an air supply docking device includes a male end 100 and a female end 200 connected to the male end 100, wherein the male end 100 includes: a guide pin 101, the interior of which is hollow, and the upper periphery of the guide pin 101 has a conical guide surface; an ejector pin 102, which is arranged inside the guide pin 101, and the interior of the ejector pin 102 is penetrated by an air guide channel 103, and the top of the ejector pin 102 has an air guide groove 104; the female end 200 includes: a mounting seat 201, which has an opening and closing cavity 202 and an installation cavity 203 inside, and the opening and closing cavity 202 is located above the installation cavity 203; the interior of the mounting seat 201 is sequentially provided with three stepped holes from bottom to top, and the radius of the three stepped holes is successively reduced, and the lowermost stepped hole An installation cavity 203 is formed, and the middle stepped hole forms an opening and closing cavity 202, and the uppermost stepped hole is used for placing and fixing a spring 208; an air outlet 204 is arranged on the side wall of the mounting seat 201 and is connected to the opening and closing cavity 202; a piston 205 is arranged in the opening and closing cavity 202 and can move up and down, and the piston 205 is used to control the connection or disconnection between the air outlet 204 and the air guide channel 103; a guide sleeve 206 is fixed in the installation cavity 203 and is used to guide the guide pin 101, the interior of the guide sleeve 206 is hollow, and the lower inner wall of the guide sleeve 206 is provided with a conical guide surface; in the initial state, the piston 205 is in contact with the guide sleeve 206, and the piston 205 is in contact with the guide sleeve 206, that is, the piston 205 blocks the air outlet 204.

[0037] In the above technical solution, the guide pin 101 is integrated into the male end 100 of the air supply docking device, and the guide sleeve 206 is integrated into the female end 200 of the air supply docking device. By relying on the tapered guide surface of the guide pin 101 to cooperate with the guide surface of the guide sleeve 206, the guide pin 101 can be accurately aligned with the guide sleeve 206, so that the guide pin 101 can be smoothly inserted into the inside of the guide sleeve 206. As the guide pin 101 is continuously inserted, since the ejector pin 102 is arranged inside the guide pin 101, the ejector pin 102 will contact the piston 205, thereby pushing the piston 205. When the piston 205 is pushed upward, the piston 205 will be separated from the guide sleeve 206 and move upward. When the piston 205 moves upward to a certain position, the air guide channel 103 inside the ejector pin 102 is connected with the air outlet 204 through the air guide groove 104, thereby realizing air supply. The air supply method is that the air inlet end is connected with the air guide channel 103 of the ejector pin 102, and the gas of the air supply device passes through the air guide channel 103, the air guide groove 104, the opening and closing cavity 202 to the air outlet 204, and the outside of the air outlet 204 is connected with other devices that need gas, thereby realizing air supply.

[0038] See also Figure 3As shown, it is worth noting that a groove is provided in the middle portion of the outer portion of the guide sleeve 206, and a rubber sealing ring is embedded in the groove. Since the guide sleeve 206 is fixedly connected to the mounting seat 201, the provision of the rubber sealing ring allows the gas to escape from the gap between the guide sleeve 206 and the mounting seat 201 during gas supply, thereby improving the sealing effect. In addition, the inner diameter of the guide sleeve 206 is smaller than the outer diameter of the piston 205.

[0039] See also Figure 1 and Figure 2 As shown, the utility model is further configured as follows: the male end 100 also includes: a mounting plate 105, which is connected to the bottom of the ejector pin 102, and a threaded groove is provided on the surface of the mounting plate 105, and the bottom of the ejector pin 102 is threadedly screwed to the threaded groove to connect the ejector pin 102 to the mounting plate 105; an air inlet hole, which is arranged at the mounting plate 105 and is connected to the air guide channel 103, and the setting of the air inlet hole is mainly to provide an air inlet channel for air supply.

[0040] As an implementation of the air inlet hole, the air inlet hole is arranged on the side of the mounting plate 105 , and an air inlet hole is opened on the side of the mounting plate 105 , and the air inlet hole extends into the threaded groove so that the air inlet hole is connected to the air guide channel 103 .

[0041] As another implementation of the air inlet, the air inlet is arranged on the back side of the mounting plate 105. The air inlet is adapted to the threaded groove, that is, the air inlet is connected to the threaded groove. In this way, air intake can be carried out on the back side of the mounting plate 105.

[0042] See also Figures 1 to 4As shown, the ejector pin 102 includes a locking section 102a, an intermediate section 102b and a connecting section 102c from top to bottom, the connecting section 102c is used to connect to the mounting plate 105, the air guide groove 104 is arranged on the top surface of the locking section 102a, the outer diameter of the locking section 102a is greater than the outer diameter of the intermediate section 102b, the outer diameter of the intermediate section 102b is greater than the outer diameter of the connecting section 102c, the outer portion of the connecting section 102c is threaded, and it is matched and connected with the threaded groove on the mounting plate 105; the guide pin 101 is fixed to the mounting plate 105 through the ejector pin 102, the interior of the guide pin 101 includes a first through hole and a second through hole arranged from top to bottom, the inner diameter of the first through hole is greater than the inner diameter of the second through hole, the first through hole and the second through hole are connected, the outer diameter of the intermediate section 102b is equal to the inner diameter of the second through hole, and the first through hole and the second through hole are connected. The inner diameter of the second through hole and the outer diameter of the locking section 102a are equal to the inner diameter of the first through hole, that is, during installation, the ejector pin 102 is first inserted into the guide pin 101, and then the ejector pin 102 is rotated so that the connecting section 102c of the ejector pin 102 is fixed to the mounting plate 105. Due to the presence of the locking section 102a, the guide pin 101 and the mounting plate 105 can be fixed. In addition, a mounting groove 106 is arranged between the intermediate section 102b and the connecting section 102c, and a sealing ring 107 is arranged in the mounting groove 106, wherein the connecting section 102c is completely screwed into the mounting plate 105, and the mounting groove 106 is located above the mounting plate 105. The installation groove 106 and the sealing ring 107 can prevent gas from leaking from between the guide pin 101 and the ejector pin 102 during gas supply.

[0043] See also Figure 3 and Figure 4 As shown, the female end 200 also includes a spring 208, one end of the spring 208 is in contact with the piston 205, and the other end of the spring 208 is in contact with the inner top of the mounting seat 201; in the above technical solution, the other end of the spring 208 is in contact with the top wall of the uppermost stepped hole in the mounting seat 201, and the uppermost stepped hole in the mounting seat 201 is located above the opening and closing cavity 202; due to its own characteristics, the spring 208 is in an extended state in the initial state, and it can press the piston 205 so that the piston 205 and the guide sleeve 206 are tightly fitted. Since the piston body of the piston 205 is a circular plate, and the outer diameter of the piston is greater than the inner diameter of the guide sleeve 206, that is, the piston 205 can close the opening and closing cavity 202 in the initial state, and when docking, the ejector pin 102 moves downward to push the piston 205 to move so that the air path is opened, and when released, the spring 208 controls the air path to be closed.

[0044] See also Figure 3As shown, the piston 205 includes a piston body and a push column arranged at the lower end of the piston body. A sealing groove is arranged in the middle of the outer wall of the piston body, and a piston sealing ring 207 is arranged in the sealing groove; the setting of the piston sealing ring 207 plays a good sealing role.

[0045] See also Figure 1 As shown, the air guide groove 104 is a cross-shaped groove. Since the piston 205 includes a push column, when the ejector pin 102 pushes the piston 205, the push column easily blocks the air guide channel 103. The setting of the air guide groove 104 can make the gas in the air guide channel 103 flow outward along the cross-shaped groove; at the same time, the setting of the air guide groove 104 also facilitates the fixing of the guide pin 101, the ejector pin 102 and the mounting plate 105.
