Description
Technical field
It the utility model is related to a kind of door latch structure.
Background technology
Lockset is installed on sliding door or unlatching door to drawing.The basic structure of above-mentioned lockset includes dead bolt seat and lock
Box, dead bolt seat are provided with the dead bolt driven by drive mechanism, and keeper is provided with lock-tongue port, when double-wing door closes, dead bolt
Penetrate and locking is carried out in lock-tongue port.The shortcomings that this lockset, is that its anti-theft feature is poor, and a dead bolt is easily pried open, and
And installation inconvenience be present simply by this lock structure and easily produce the imprecise phenomenon of locking.
Utility model content
Main purpose of the present utility model is to provide a kind of door latch structure, it is intended to it can realize dual locking, Dual positioning,
Ensure the stability of overall folding, improve its anti-theft feature, and improve locking effect.
The utility model proposes a kind of door latch structure, including the dead bolt seat and lock being separately mounted on door leaf and doorframe
Box, its design feature are：Shown dead bolt seat is provided with vertical spaced two card columns, and the apparent surface of keeper is provided with
For the neck of card column insertion, it is fitted with dead bolt seat to be driven by drive mechanism and slides along and two locks that horizontal parallel is set
Tongue, the apparent surface of the keeper are provided with two lock-tongue ports stretched into for dead bolt.
Described two dead bolts include the small small dead bolt of the big big dead bolt of a diameter and a diameter, and small dead bolt is located at two
Between card column.
Lockplate is connected with the keeper, lockplate is provided with the locking mouth that position is correspondingly arranged with lock-tongue port.
The lockplate is provided with a strip hole and a circular hole, and a strip hole and one also are provided with the keeper
Individual circular hole, and the strip hole on lockplate is corresponding with the circular hole on keeper, the length on circular hole and keeper on lockplate
Bar hole is corresponding, and connecting bolt is coated with corresponding strip hole and circular hole.
The leading section of the dead bolt is provided with locking step, the diameter of the locking mouth be less than lock-tongue port and lock the size of mouth with
The size of locking step is adapted.
After said structure, coordinated by card column with neck and once closed, two dead bolts enter with two lock-tongue ports
Capable locking again, it is thus achieved that locking twice, and two dead bolts lock simultaneously, substantially increase anti-theft feature.Small lock
Tongue improves the concealment of small dead bolt, further increases anti-theft feature between two card columns；Box like structure is exactly to be
Support and debris enters during anti-installation from when installation, influences the operation of inner structure；The lockplate of setting, dead bolt penetrate lock
When in button box, dead bolt can pass through the stop of keeper side wall and lockplate, improve its anti-theft feature, lockplate can realize position
Adjustment is put, so as to reach optimum position, the locking step of setting and the cooperation of locking mouth further increase its anti-theft
Energy.
In summary, the utility model can realize dual locking, Dual positioning, ensure the stability of overall folding, have
There is the advantages of tight locking, good anti-theft effect.
Brief description of the drawings
Fig. 1 is a kind of explosive view of embodiment of the utility model；
