Lock tongue touch device for automatic lock

Abstract

The invention provides an oblique tongue touch device of an automatic lock and belongs to the technical field of hardware door lock accessories. The problems that the existing automatic lock is inconvenient to lock and the like are solved. The oblique tongue touch device comprises an oblique tongue rod, an oblique tongue, a shifting plate, a stop block, an abutting mechanism and an oblique tongue resetting mechanism, wherein the stop block is in rotating connection with a lock box through a fixed shaft, and the stop block swings around the fixed shaft, enabling a stop part on the stop block to switch between a locking position and an unlocking position; the shifting plate is located at the side part of the oblique tongue rod, the inner end of the shifting plate is in rotating connection with the stop block, the outer end of the shifting plate faces the oblique tongue, and a hooking opening is formed in the shifting plate; the side, facing the shifting plate, of the oblique tongue rod is provided with a hook fastener corresponding to the hooking opening; when the oblique tongue retracts, the hook fastener can fall into the hooking opening with the movement of the oblique tongue rod, forming hooking connection; and the outer end of the shifting plate is provided with an oblique surface which can be pushed away from the oblique tongue rod by an oblique tongue shifting fork. After the oblique tongue is locked, a lock tongue plate can automatically pop up, the locking of a main lock tongue is finished, and the trouble of locking with a key is avoided.

Description

technical field [0001] The invention belongs to the technical field of hardware door lock accessories, and in particular relates to an oblique tongue touch device of an automatic lock. Background technique [0002] Existing automatic locks generally include a lock box, a dead bolt (comprising a bolt and a main dead bolt) arranged on the lock box, and a side panel arranged on one side of the lock box and having a dead bolt hole. Matching, the deadbolt can extend into the deadbolt hole (the oblique bolt corresponds to the oblique bolt hole, and the main deadbolt corresponds to the main deadbolt hole). [0003] In the existing automatic lock, generally the locking of the bolt bolt and the main bolt is independent, that is, the locking of the bolt bolt only needs to close the door, and the bolt bolt can be locked by entering the bolt bolt hole, while the main lock The locking of the tongue also needs the cooperation of the key or the handle, and the anti-theft effect of the loc...

Problems solved by technology

[0003] In the existing automatic lock, generally the locking of the bolt bolt and the main bolt is independent, that is, the locking of the bolt bolt only needs to close the door, and the bolt bolt enters the bolt hole to achieve the locking of the bolt bolt, while the main lock The locking of the tongue also needs the cooperation of the key or the handle, and the anti-theft effect of the lock can be better after the oblique tongue and the main bolt are locked together. However, people often forget the lock of the main bolt after they take the door (close the door). In this way, the anti-theft ability of the door is greatly weakened. Therefore, it is necessary to propose a latch bolt touch device that can drive the main bolt to lock together at the same time.
