The invention discloses a door bolt with a self-locking preventing function. The door bolt with the self-locking preventing function comprises a door leaf connecting part, a door frame connecting part and an L-shaped door bolt rod. Three first connecting lugs are arranged on the door leaf connecting part. Two second connecting lugs are arranged on the door frame connecting part. The L-shaped door bolt rod penetrates through the first connecting lugs and the second connecting lugs. The door bolt with the self-locking preventing function further comprises a spring. The L-shaped door bolt rod is provided with a stop lever. The stop lever is perpendicular to the L-shaped door bolt rod. One end of the spring abuts against the stop lever and penetrates through the first connecting lug in the middle, and the other end of the spring abuts against another first connecting lug. The door bolt with the self-locking preventing function has the advantages that since the door bolt is provided with the spring, the door bolt rod can be automatically kept in an ejected state, and thus self-locking or automatic unlocking is avoided; and the structure is simple, and using is quite convenient.
Description
technical field [0001] The invention relates to an anti-self-locking door bolt. Background technique [0002] Door bolt is a common device in daily life. It is a device that can open and close the door from the inside, but cannot open and close the door from the outside.
