technical field

The utility model relates to the technical field of door and window accessories, in particular to an anti-theft bar lock with a simple structure.

Background technique

Sliding doors and windows generally use bar locks. Most of the bar locks on the market have obvious operating noises, loose structures, and no anti-pick function. When outdoors, you can lift the side of the door and window fan with the bar lock to unlock the bar lock. , the locking function is invalid and cannot meet the requirements of anti-theft. Although some bar locks have an anti-pick function, there are many small parts and it is inconvenient to assemble, which eventually leads to the inability of the bar lock to operate and lock.

Utility model content

The technical problem to be solved by the present utility model is: to provide an anti-theft bar lock with a simple structure, so as to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or create conditions.

The solution that the utility model solves its technical problem is:

An anti-theft bar lock with a simple structure is provided with mutually orthogonal X, Y and Z directions; the anti-theft bar lock includes:

a lock body, the lock body is provided with a card position lock hole;

A toggle bar, the toggle bar is provided with a toggle structure, and the toggle structure is correspondingly arranged with the card position lock hole; the toggle bar includes:

a lock seat part, the lock seat part is slidingly connected with the lock body along the X direction; the lock seat part is connected with a lock hook seat, the lock hook seat and the lock seat part are relatively fixed, the lock hook The seat is connected with a lock hook body;

a locking portion, the locking portion is elastically connected with the locking seat portion; the locking portion is provided with a locking protrusion, and the locking protrusion is used for abutting with the wall surface of the locking hole, so as to The relative position of the lock body and the toggle bar is defined.

Through the above technical solution, when the anti-theft bar lock is in the locked state, the locking protrusion of the toggle bar will be stuck in the locking hole of the lock body, so that the lock hook cannot move down without operating the toggle bar, preventing theft from theft. The bar lock cannot be unlocked. When operating the toggle bar to change the anti-theft bar lock from the locked state to the open state, before the operator drives the toggle bar to move downwards, first press the detent part of the toggle bar to the inside of the window sash to make the toggle bar lock. The closing protrusion is separated from the hole of the lock body. At this time, the operator can drive the toggle bar to move in the X direction, thereby driving the lock hook body to move, so that the lock hook body and the lock point of the fan frame are separated, so that the anti-theft bar lock is in the open state. . When the toggle bar is operated to change the anti-theft bar lock from the open state to the locked state, due to the action of the elastic force, when the locking protrusion moves to the latching lock hole, the latching part will reset to lock the lock body again. Holes on the front.
