Description

Automatically flexible lock body

Technical field

The utility model relates to a kind of automatically flexible lock body, and is flexible especially automatically.

Technical background

At present known general lock body all is to adopt rotary type to unblank, and unblanks, locks that it is very inconvenient to use, and is easily pried open by force or with similar TO, theftproof performance is not strong.

In order to overcome the technical deficiency of existing lock body, the utility model provides a kind of automatically flexible lock body, and this flexible automatically lock body is easy to use, the back self-return of unblanking, but lock without the key self-return when locking, easy to use, simple in structure.

The technical scheme that its technical problem that solves the utility model adopts is to draw between position, angle (7) dead bolt rotor (8) the lock core location convex body (9) at lock tongue body (4) dead bolt projection (5) and dead bolt to fit into top pressure spring (6), like this lock tongue body (4) dead bolt projection (5) top pressure spring (6) dead bolt is drawn position, angle (7) dead bolt rotor (8) lock core location convex body (9) lock core card kerve (10) lock core turning set (11) to fuse, self-return after unblanking, but lock without the key self-return when locking, easy to use.

The beneficial effects of the utility model be unblank the back self-return, utilize top pressure spring (6) without key when locking but self-return is locked, it is easy to use to unblank, lock, simple in structure.
