Abstract

The present invention relates to an automatic lock, which includes an operation board, an inclined tongue, a burglarproof bolt, an abutting member latch bolt and a straight tongue. In a normal status, the abutting member latch bolt on the burglarproof bolt supports the operation board, at this moment, if only the burglarproof bolt is pushed, the abutting member latch bolt is abutted accordingly by the operation board and becomes unable to move; when the inclined tongue and the burglarproof bolt are both retracted, this time it is the inclined tongue that supports and upwardly pushes the operation board, thus enabling the abutting member latch bolt to move with the burglarproof bolt and temporally unable to support the operation board; when the inclined tongue, the burglarproof bolt and the straight tongue are corresponding to a door frame, and the inclined tongue and the burglarproof bolt are respectively pushed into a hole, there is a moment that the operation board is not supported by the inclined tongue and the abutting member latch bolt and thus will be downwardly pushed, and the straight tongue is pushed out for entering the door frame; accordingly, the straight tongue can only be pushed out when the inclined tongue and the burglarproof bolt are both recovered, so the location of the straight tongue can be ensured to be corresponding to a straight tongue hole of the door frame, thus the objective of secured locking is achieved.

Description

Automatic lock

The present invention relates to a lock provided on a door, and more particularly to an automatic lock that automatically locks when the door is closed, and is an automatic lock that ensures that the lock tongue is locked in the correct position.

Referring to FIG. 17 and FIG. 18, the prior art automatic lock includes a lock housing 210, an anti-theft bolt 220, a tilting tongue 230, a straight tongue 240 and an actuating plate 250. The lock housing 210 is provided with a lock. The side plate 211; the anti-theft bolt 220, the oblique tongue 230 and the straight tongue 240 selectively protrude from the locking side plate 211 of the lock housing 210, and the anti-theft bolt 220 and the oblique tongue 230 are respectively pushed by the spring to protrude outside the locking side plate 211. The straight tongue 240 is controlled by the actuating plate 250; the actuating plate 250 is disposed upright in the lock housing 210. When the moving plate 250 is moved down to the positioning, the straight tongue 240 protrudes out of the locking side plate 211 as the moving plate 250. When moving to the positioning, the straight tongue 240 is retracted into the locking side plate 211; and the actuating plate 250 is pushed by the spring to move downward, but the actuating plate 250 is selectively engaged with the inner end of the anti-theft bolt 220. When the bolt 220 protrudes from the outside of the locking side plate 211, the anti-theft bolt 220 engages the actuating plate 250 so that the actuating plate 250 cannot be moved downward, and when the anti-theft bolt 220 is retracted into the locking side plate 211, the actuating plate 250 is disengaged from the anti-theft. The pin 220 is pushed down to the position.

In this way, after the door leaf of the present invention is opened, the anti-theft bolt 220 and the oblique tongue 230 protrude from the locking side plate 211, and the actuating plate 250 is located at the upper position to engage with the anti-theft bolt 220, and the straight tongue 240 is Limited to the actuating plate 250 and located in the locking side plate 211; when the door leaf is closed, the anti-theft bolt 220 is pushed inward by the door frame to the locking side plate 211, and thus the actuating plate 250 is released, the actuating plate 250 is moved down and the tongue is straightened 240 pushes out the locking side plate 211, so that the straight tongue 240 can thus protrude into the tongue of the mouth piece of the door frame, and thereby achieve the purpose of automatic locking.

However, the prior art automatic lock has the disadvantage that when the door leaf is closed, the anti-theft bolt 220 is only slightly pushed in a short distance, and the actuating plate 250 will immediately disengage from the anti-theft bolt 220 and quickly move down and push the straight tongue 240 out, but At this time, the position of the straight tongue 240 may not correspond to the door frame at all, so that the protruding straight tongue 240 has the possibility of abutting against the outer side of the door frame, and the door leaf cannot be closed.

In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an automatic lock to ensure that the position of the straight tongue corresponds to the straight tongue of the mouthpiece on the door frame before the straight tongue is extended.

In order to achieve the above object, the technical means adopted by the present invention is to design an automatic lock, which comprises: a lock housing comprising an assembly plate and a locking side plate; the locking side plate is vertically connected to the lateral direction of the assembly plate a side plate; an actuating plate, which is arranged to be movable up and down in the lock housing, and a slanting tongue groove is recessed on a lateral side of the actuating plate adjacent to the locking side plate; the urging plate is provided with an anti-theft bolt hole; a long hole extending upwardly and upwardly, and a shackle hole protrudes from a lateral side of the locking side plate with a pressing protrusion; an actuating plate elastic member is disposed on the lock housing and pushes the action plate downward; a tongue, which is laterally movably disposed in the lock housing, and selectively protrudes outside the lock side panel and selectively abuts upwardly in the slant tongue groove of the actuating plate; a slanting tongue elastic member is disposed on the lock a slanting tongue is pushed onto the housing, and the slanting tongue is pushed to the locking side panel; the tamper bolt is laterally movably disposed in the lock housing and selectively protrudes outside the locking side panel; the anti-theft bolt protrudes with an abutting portion; Bolt elastic element, its design On the lock housing, and pushing the anti-theft bolt to the lock side plate; an abutment clip, which is laterally movable on the anti-theft bolt, and is inserted in the anti-theft bolt hole of the actuation plate, and selectively upward a pressing protrusion against the tamper hole; when the slanting tongue abuts against the slanting tongue groove of the actuating plate, the pressing rib is upwardly disengaged from the abutting latch; and the abutting member latches the elastic member Relying on the abutment latch and abutting the abutment latch against the abutment of the anti-theft latch; a tongue that is laterally displaceable within the lock housing and selectively protruding from the lock of the lock housing The side plate is outside; the straight tongue is connected to the actuating plate and is pushed by the actuating plate.
