The locking baffle is designed for realizing the automatic locking function of the male connector. The function of the locking device is to automatically lock the male connector after the male connector and the female connector are mutually matched and tightly, and no external operation is needed again. Only after the male joint and the female joint are tightly matched, the locking baffle can move forwards under the action of the spring and automatically pop up. Meanwhile, the connection indicating ring is designed around the locking baffle, so that people can observe and perceive the connection state of the connector more intuitively. 4. As a means of safety protection, in order to avoid the accidental disconnection of the joint caused by the accidental contact of a person on the joint and reduce unnecessary maintenance, a mistaken contact prevention ring is designed on the outer part of the female joint. The anti-false-touch stop ring can be operated only after the male joint and the female joint are connected in place and are mutually communicated, and the anti-false-touch stop ring can not act no matter what kind of operation is carried out on the anti-false-touch stop ring at ordinary times. 5. In order to realize the direction change operation of the joint, a rotary sealing part is designed. The valve core not only can display the direction change operation of changing 180 degrees to 90 degrees of the joint, but also is a sealing movable valve core of a normally closed valve. When the joint is pulled along the arrow direction, the normally closed valve can be opened. 6. The locking stop sleeve not only serves as a locking mechanism of a normally closed valve, but also serves as an indicating device for opening the normally closed valve. The switching-on indicating sleeve is designed around the locking baffle 2, after the normally-closed valve is opened, the locking blocking sleeve can be popped out outwards, and the switching-on indicating sleeve can be seen, so that a person can visually observe the state of the normally-closed valve.
