Light touch type lock-tongue lock
The invention relates to a light touch type lock-tongue lock. An elastic hook is mounted on a lock body. Due to the shape of the elastic hook, the elastic hook can hook a lock tongue under the elastic action and can also unhook the lock tongue when being touched. Due to the mounting position of the elastic hook on the lock body, after the lock tongue is retracted into the lock body, the elastic hook just hooks the lock tongue and prevents the lock tongue from rebounding and extending out of the lock body; when the lock tongue reaches to a position opposite to a lock hole along with the closing motion of a lock body mounting object, the elastic hook is just touched by a lock hole mounting object so as to unhook the lock tongue. The light touch type lock-tongue lock has the advantages that when the lock body mounting object such as doors and windows is closed, the lock tongue cannot collide with the lock hole mounting object such as doorframes and window frames, so that the noises caused by closing the lock body mounting object such as the doors and the windows are greatly reduced, and the service life of the whole lock and the lock body mounting object is prolonged; on the other hand, the requirement on the output power of an automatic door closer is reduced, and the lightweight of the automatic door closer is facilitated.
