Abstract
The utility model is a kind of pick-proof lock, between dead bolt (2-1) the inner and dead bolt housing (2), spring (2-2) is installed; Also comprise the stay cord (3) that is positioned at a body (1), one end of described stay cord (3) is connected with dead bolt (2-1); Also comprise and be positioned at a body (1) inside, end face is arranged on the lock core linkage gear (5) on a body (1) shell; In this lock core linkage gear (5) top, be provided with gangbar (6), described gangbar (6) lower end is provided with the tooth for coordinating with lock core linkage gear (5); The outer end of described gangbar (6) is unsettled, and the inner is connected with the other end of stay cord (3).After lock core linkage gear is by outside destroy, gangbar loses support, under the effect of gravity, in door body, drops, and dead bolt still pins door, prevents that door is opened.Therefore there is good pick-proof lock function.
Description
Technical field
The utility model relates to a kind of pick-proof lock.
Background technology
Its lock core of existing lockset is close with latch bolt position and adopt simple pinion and rack to fix.Therefore when using the instruments such as electric drill lock core to be bored after taking-up thoroughly, can at an easy rate the dead bolt of cease to bind be taken out, thereby open door.Therefore developing a kind of lockset that can still can pin door after lock core is destroyed is industry technical problem urgently to be resolved hurrily.
Utility model content
Technical problem to be solved in the utility model is, a kind of pick-proof lock is provided, and after lock core is destroyed, still can pin door, has tamper-resistant function.
It is as follows that the utility model solves the problems of the technologies described above adopted technical scheme:
A pick-proof lock, is characterized in that: comprise and be arranged on hollow door body upper edge along the dead bolt housing at position, in dead bolt housing, dead bolt is installed, between dead bolt the inner and dead bolt housing, spring is installed; Also comprise the stay cord that is positioned at a body, one end of described stay cord is connected with dead bolt; Also comprise the guiding roller bearing being arranged in a body, described guiding roller bearing is positioned at the below of described dead bolt housing; Also comprise the lock core linkage gear that is arranged on Men Tizhong; Above this lock core linkage gear, be provided with gangbar, described gangbar lower end is provided with for the tooth with the engagement of lock core linkage gear; The outer end of described gangbar is unsettled, and the inner is connected with the other end of stay cord; Gangbar relies on lock core linkage gear to support; Above described gangbar, be provided with two blocks, within described block is fixedly mounted on a body; The lower end of block is provided with arc groove, and described gangbar is positioned at arc groove, and arc groove is for carrying out spacing to gangbar.
Good effect of the present utility model is:
After lock core linkage gear is by outside destroy, gangbar loses support, under the effect of gravity, in door body, drops, and dead bolt still pins door, prevents that door is opened.Therefore there is good pick-proof lock function.
accompanying drawing explanation
Fig. 1 is the structural representation of a body.
Fig. 2 is the structural representation of spring bolt mechanism.
Fig. 3 is the planform schematic diagram of block.
Fig. 4 is the structural representation of lock core linkage gear and gangbar.
The specific embodiment
Below in conjunction with drawings and Examples, further illustrate the utility model.
As Fig. 1,2, the present embodiment comprises and is arranged on hollow door body 1 upper edge along the dead bolt housing 2 at position, and dead bolt 2-1 is installed in dead bolt housing 2, between the inner and dead bolt housing 2 of dead bolt 2-1, spring 2-2 is installed.Also comprise the stay cord 3 that is positioned at a body 1, one end of described stay cord 3 is connected with dead bolt 2-1.Also comprise the guiding roller bearing 1-1 being arranged in a body 1, described guiding roller bearing 1-1 is positioned at the below of described dead bolt housing 2.
As Fig. 4, also comprise the lock core linkage gear 5 being arranged in a body 1.Above this lock core linkage gear 5, be provided with gangbar 6, described gangbar 6 lower ends are provided with for the tooth with 5 engagements of lock core linkage gear.The outer end of described gangbar 6 is unsettled, and the inner is connected with the other end of stay cord 3.Gangbar 6 relies on lock core linkage gear 5 to support.
Above described gangbar 6, be provided with at least two blocks 4 as shown in Figure 3, within described block 4 is fixedly mounted on a body 1.The lower end of block 4 is provided with arc groove, and described gangbar 6 is positioned at arc groove, and arc groove is spacing for gangbar 6 is carried out, and prevents perk or front and back skew.
While unblanking, key inserts the 5 rear rotations of lock core linkage gear, and lock core linkage gear 5 drives the gangbar 6 being engaged with outwards to move, thereby gangbar 6 inwardly pulls stay cord 3 to make dead bolt 2-1 depart from dead bolt hole, unblanks.
Described stay cord 3 can be wire rope.
After lock core linkage gear 5 is by outside destroy, gangbar 6 loses support, under the effect of gravity, in door body, drops, and dead bolt still pins door, prevents that door is opened.
