In-line sliding door and window lock

Abstract

The invention discloses a direct insertion type sliding door / window lock. The direct insertion type sliding door / window lock comprises a lock body and a strip-shaped lock tongue which can be inserted in the lock body from one side of the lock body, wherein both sides of the inside of the lock body are provided with pawl-shaped swinging parts which can be against both sides of the lock tongue to prevent that the lock tongue is drawn out of the lock body and also provided with springs which are used to keep the swinging directions of the swinging parts and are tightly against the lock tongue, the inside of the lock body is also provided with a slider releaser which performs reciprocating motion to the lock tongue, and shifting parts which can shift the swinging parts from the lock tongue are formed on both sides of the end facing to the lock tongue, of the releaser. The swinging parts on both sides are used to clamp the lock tongue and realize locking; and when a door / window is opened a little and leaves a gap, the door / window can also be locked. In addition, the door / window lock utilizes the principle of the pawl so that the lock tongue is difficult to draw out when a shifting releaser is not used; and if the lock is forced to be pried, the larger the force is, the more tightly the lock tongue is locked. Therefore, the direct insertion type sliding door / window lock has excellent anti-prying property, anti-theft property and anti-wind pressure property.

Description

technical field [0001] The invention relates to the technical field of sliding door and window locks. Background technique [0002] The existing sliding door and window locks are mostly automatic knuckles or manual crescent locks, which use the shape and position difference between the parts and the interlocking fastening. Wind pressure performance is even lacking. And when the sliding doors and windows are locked, the door and window sash and the door and window frame are locked in a relatively fixed position, and usually can be locked when the door and window sash is closed. And when the doors and windows are opened a little, leaving a slit to keep the indoor and outdoor air circulation, the doors and windows cannot be locked. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a push-pull door and window lock with high structural strength, excellent anti-prying, anti-theft performance and wind pressure resistanc...
