Abstract
A lockset for a pry-proof door comprises a primary lockset arranged in a door leaf, wherein the primary bolt of the primary lockset can be inserted into or pulled out from a primary lock hole of a door frame. The lockset is characterized in that an opening is formed on the primary bolt, a secondary lockset is arranged inside the door frame, and a lock barrel is arranged inside the secondary lockset and drives the bolt of the secondary lockset to be inserted into or pulled out from the opening on the primary bolt. The lockset can be locked by inserting the primary bolt of the primary lockset into the primary lock hole of the door frame and then operating the secondary lockset to insert the bolt of the second lockset into the opening on the primary bolt, so as to form interlock between the primary lockset and the secondary lockset. The lockset provided by the utility model has greatly improved pry-proof performance.
Description
Technical field:
The utility model relates to the pick-proof door lock.
Background technology:
At present, various pick-proof door lock structures are numerous.A kind of " twin-lock security door " just disclosed for No. 200520101524.6 as Chinese patent.In this technical scheme, the twin-lock security door comprises: doorframe, door leaf, theftproof lock, theftproof lock comprises lock core, main lock body, lock core cooperates with main dead bolt on the main lock body by the lock core shifting block, be provided with main lockhole with the corresponding doorframe of main dead bolt, main lock body is arranged on the ladder of the second level, the lock core in same cross section, the main lock body outside is provided with auxiliary lock body, auxiliary lock body is fixed on the first order ladder of door leaf, lock core is provided with the auxiliary lock core shifting block, secondary dead bolt coupling on auxiliary lock core shifting block and the auxiliary lock body, the doorframe corresponding with secondary dead bolt is provided with secondary lockhole.The security door of said structure can be to a certain degree raising pick-proof performance, but it has the following disadvantages: because above-mentioned anti-main dead bolt and secondary dead bolt of forcing open the door all directly inserts in the doorframe lockhole separately, no mutual locking action between two dead bolts, when violence is forced open the door, main dead bolt and secondary dead bolt can be deviate from from doorframe, just door can be pushed open, make that the pick-proof performance of above-mentioned lockset is undesirable.
Summary of the invention:
The purpose of this utility model is: provide between a kind of two locks and can lock the pick-proof door lock that the pick-proof performance is desirable mutually.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of pick-proof door lock, comprise: be located at the main lockset in the door leaf, the main dead bolt of main lockset can insert or withdraw from the main lockhole of doorframe, it is characterized in that: described main dead bolt is provided with perforate, be provided with secondary lockset in the doorframe, be provided with lock core in the secondary lockset, lock core drives secondary lockset dead bolt and inserts or withdraw from perforate on the main dead bolt.
Advantage of the present utility model is: because main dead bolt is provided with perforate, be provided with secondary lockset in the doorframe, secondary lockset dead bolt can insert or withdraw from the perforate on the main dead bolt.During locking, in the main lockhole in the main dead bolt insertion doorframe of main lockset; Operate secondary lockset again, make secondary lockset dead bolt insert perforate on the main dead bolt.At this moment, just between main lockset and secondary lockset, form interlocking, thereby improve the pick-proof performance of lockset greatly.When unblanking, first open auxiliary lockset makes secondary lockset dead bolt withdraw from perforate on the main dead bolt, opens main lockset again and just can.Pick-proof door lock of the present utility model is not when needing to protect especially, and secondary lockset can not use.
In the utility model, described secondary lockset comprises: the lock core rear end is provided with bolt, and bolt drives secondary lockset dead bolt planker and moves, and secondary lockset dead bolt planker drives secondary lockset dead bolt and inserts perforate on the main dead bolt; Secondary lockset dead bolt planker is provided with lead and back-moving spring.Secondary lockset adopts said structure, its simple in structure, reliable operation, low cost of manufacture.
In the utility model, described main lockset is provided with multidirectional main dead bolt, is provided with in the multidirectional main dead bolt of at least one of main lockset for the secondary dead bolt insertion of secondary lockset or the perforate of withdrawing from.Main lockset of the present utility model can be locksets such as multidirectional lock pin lock commonly used at present, multidirectional automatic locking, and when main lockset employing had the lockset of multidirectional lock function, secondary lockset can only be located on the dead bolt, also secondary lockset can be set all on each dead bolt.
Description of drawings:
Fig. 1 is that the utility model is located at the main lock structure schematic diagram on the door leaf.
Fig. 2 is a schematic diagram when being located on the doorframe secondary lockset dead bolt and not inserting on the main lockset master dead bolt perforate.
Fig. 3 is a generalized section when being located on the doorframe secondary lockset dead bolt and entering on the main lockset master dead bolt perforate.
The specific embodiment:
In conjunction with Fig. 1, Fig. 2, shown in Figure 3: the pick-proof door lock of present embodiment comprises: be located at the main lockset 1 in the door leaf, the main dead bolt 2 of main lockset can insert or withdraw from the main lockhole of doorframe.Main dead bolt is provided with perforate 3, is provided with secondary lockset in the doorframe, is provided with lock core 6 in the secondary lockset 4, and the secondary lockset dead bolt 5 of lock core 6 drives inserts or withdraw from the perforate 3 on the main dead bolt.Secondary lockset comprises: lock core 6 rear ends are provided with bolt 7, and bolt drives secondary lockset dead bolt planker 8 and moves, and secondary lockset dead bolt planker 8 drives the perforate 3 that secondary lockset dead bolt 5 inserts on the main dead bolt; Secondary dead bolt planker is provided with lead 9 and back-moving spring 10.
Because main dead bolt is provided with perforate, be provided with secondary lockset in the doorframe, secondary lockset dead bolt can insert or withdraw from the perforate on the main dead bolt.During locking, in the main lockhole in the main dead bolt insertion doorframe of main lockset; Operate secondary lockset again, secondary lockset dead bolt is inserted in the perforate on the main dead bolt.At this moment, just between main lockset and secondary lockset, form interlocking, thereby improve the pick-proof performance of lockset greatly.When unblanking, first open auxiliary lockset makes secondary lockset dead bolt withdraw from perforate on the main dead bolt, opens main lockset again and just can.Pick-proof door lock of the present utility model is not when needing to protect especially, and secondary lockset can not use.Secondary lockset adopts said structure, its simple in structure, reliable operation, low cost of manufacture.
Main lockset of the present utility model is provided with multidirectional main dead bolt, is provided with in the multidirectional main dead bolt of at least one of main lockset for the secondary dead bolt insertion of secondary lockset or the perforate of withdrawing from.When main lockset employing had the lockset of multidirectional lock function, secondary lockset can only be located on the dead bolt, also secondary lockset can be set all on each dead bolt.
