Abstract
This is a lock of an anti-pry door, comprising a lock case and a lockset panel which is arranged on the front end of the lock case, and the lock case is provided with a bolt, a shift lever drives the expansion of bolt. The frame of the anti-pry door is provided with a lock hole which cooperates with the bolt. The lock is characterized in that: the bolt panel is provided with the right open box-shaped hems, the front hems can insert into the opening of the anti-pry door frame, and the front herms are provided with a socket which co-works with the bolt. When the anti-pry door is opened and closed normally, the front hems can insert into or withdraw from the opening of the anti-pry door frame easily; the bolt can be conveniently inserted into or withdrawn from the lock hole of the anti-pry door frame and the socket in the front hems of the lock panel. When the door is pried, the deformation of the anti-pry door frame or the anti-pry door makes the bolt and the lock hole on the anti-pry door frame and the socket on the front hems of the lock panel lock together. Certainly, when the door is pried, the deformation of the anti-pry door frame or the door can also make the front hems of the lock panel and the opening in the anti-pry door frame lock together, so, the door can not be opened even if the anti-pry door is pried, thus the anti-prying performance of the anti-pry door can be improved greatly.
Description
Technical field:
The utility model relates to a kind of anti-limit lock of forcing open the door.
Background technology:
For improving anti-pick-proof performance of forcing open the door, existing pick-proof gate open is standing to have the pick-proof limit to lock.As Chinese patent a kind of " security door limit lock " just proposed for No. 01228458.0.In this technical scheme, the security door limit is locked on the door leaf side.At closing time, limit lock enters lockhole in the doorframe with main lock, the raising pick-proof performance that it can be to a certain degree.But by sled the time, the limit lock can not make between door leaf and doorframe and form interlocking, makes that the pick-proof performance of the existing anti-limit lock of forcing open the door is undesirable.
Summary of the invention:
The purpose of this utility model is: the anti-limit lock of forcing open the door that can make interlocking between door leaf and doorframe when a kind of the sled is provided.The utility model is achieved through the following technical solutions:
A kind of anti-limit lock of forcing open the door comprises: lock housing and the panel of lock of being located at the lock housing front end, be provided with dead bolt in the lock housing, and it is flexible that driving lever drives dead bolt; Pick-proof every frame is provided with the lockhole that matches with dead bolt; It is characterized in that: described latch bolt panel is provided with " Contraband " shape flanging, and the leading portion flanging can insert on pick-proof every frame in the perforate, and the leading portion flanging is provided with and the corresponding jack of dead bolt.During normal open and close door, the leading portion flanging can insert or withdraw from perforate on pick-proof every frame easily; Dead bolt can insert or withdraw from lockhole on the doorframe and the jack on the lock panel leading portion flanging of limit easily.By when sled, the deformation on door leaf or the doorframe makes between lockhole on dead bolt and the pick-proof every frame, the jack on the lock panel leading portion flanging of limit and forms interlocking.Certainly, by sled the time, the deformation on door leaf or the doorframe also can make on limit lock panel leading portion flanging and the doorframe and form interlocking between perforate.Even thereby realize that anti-forcing open the door prized also and can't be opened the door, improved anti-pick-proof performance of forcing open the door greatly.
In the utility model, described dead bolt planker is provided with pin, and driving lever is provided with elongated hole, and lock housing is provided with straight trough, and driving lever can rotate around fulcrum, moves in elongated hole that the pin on the dead bolt planker can be on driving lever and the straight trough on the lock housing.The limit lock construction of said structure is simple, easily manufactured.

Fig. 6 is the utility model embodiment 1 anti-limit lock scheme of installation of forcing open the door.
The specific embodiment:
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6: the anti-limit lock of forcing open the door of present embodiment comprises: lock housing 1 and be located at the panel of lock 2 of lock housing front end, be provided with dead bolt 3 in the lock housing, and it is flexible that driving lever 4 drives dead bolts 3; Pick-proof every frame 5 is provided with the lockhole 6 that matches with dead bolt.Latch bolt panel 2 is provided with " Contraband " shape flanging, and leading portion flanging 7 can insert on pick-proof every frame in the perforate 8, and leading portion flanging 7 is provided with and the corresponding jack 9 of dead bolt.
The anti-limit lockset of forcing open the door of present embodiment has makes the function that forms interlocking between door leaf 12 and doorframe, thereby has improved anti-pick-proof performance of forcing open the door greatly.And the limit lock is simple in structure, easily manufactured.
