[0020] Working principle: When the new structure self-locking joint is used, the air pipe plug can be inserted from the inner hole on the back of the valve body 11. The front chamfer of the plug pushes the slide post 9 open. When the rear chamfer of the plug is inserted into the inclined groove position on the valve body 11, the slide post 9 is reset under the action of the slide post reset spring 7 and the air pipe plug is locked. At the same time, the front end of the plug is inserted into the air pipe plug O-ring 6 to form a seal and push the valve core 4 open to open the valve. When the plug is inserted along the inclined groove position on the valve body 11, the slide post 9 is reset under the action of the slide post reset spring 7 and the air pipe plug is locked. At the same time, the plug is inserted into the air pipe plug O-ring 6 to form a seal and push the valve core 4 open to open the valve. Figure 2 When the sliding sleeve 12 is pushed by external force in the direction of the arrow, the sliding sleeve 12 pushes away the sliding column 9, and the locking of the sliding column 9 on the trachea plug can be released, so that the trachea plug can be easily pulled out. When the trachea plug is not inserted, the valve core 4 blocks the valve port of the valve body 11 near the threaded connector 1 under the action of the valve core return spring 3 and the air pressure, and the compressed air cannot pass through the threaded connector 1 and the valve body 11. When the trachea plug is inserted into the inner hole of the valve body 11, the trachea plug pushes open the valve core 4, the valve port of the valve body 11 is opened, and the compressed air can pass through the threaded connector 1 and the valve body 11. An oblique groove is provided on the outside of the valve body 11 near the sliding column 9. The sliding column return spring 7, the retaining ring 8, the sliding column 9 and the oblique groove on the valve body 11 constitute a locking mechanism. The valve body 11, The threaded connector 1 and the sliding sleeve 12 are connected by a sleeve connection and are limited by a wire retaining ring 10. The sliding column return spring 7, the retaining ring 8, the sliding column 9 and the valve body 11 are sleeve-connected. The valve body 11 and the threaded connector 1 are screwed together and sealed by a valve body O-ring 2. The valve core 4 and the valve body 11 are sleeve-connected. The valve core 4 and the valve core return spring 3, the valve core O-ring 5, and the trachea plug O-ring 6 are sleeve-connected. When the trachea plug is inserted into the valve body 11, the trachea plug can be inserted without pushing the sliding sleeve 12, and after being inserted to a certain position, the sliding column 9 is reset to lock the trachea plug. The joint has a simple and compact structure, and the plug is easy to insert and remove, has good air tightness, and works stably and reliably.
