Abstract

The utility model relates to a novel theft-proof lock head, comprising a lock head case, a rotational lock core, a shift fork, a plurality of pins or spring plates, which is characterized in that: the lock core inside the lock head case can be singly or doubly separated into single or compound separation lock core using clapboard; the springs inside the lock core can be arranged laterally according to different shapes of the lock hole; a clapboard is arranged at the cross section of the lock core inside the lock head case to prevent the cross section of the lock core from revealing. The utility model has the advantages that: the utility model has the theft-proof performance that prevents opening the lock using master key or modern technological measures such as electrical pulsator and unlocking gun; at the same time, normal opening using matched keys is not affected.

Description

A kind of novel anti-theft tapered end

One, technical field:

The utility model relates to a kind of lockset, particularly a kind of novel anti-theft tapered end.

Two, background technology:

Existing tapered end generally comprises tapered end housing, lock core, shift fork, pellet shot from a slingshot or shell fragment.Tapered end only when all pellets shot from a slingshot are in ad-hoc location simultaneously lock core could rotate, thereby drive the shift fork running lockset is opened.This tapered end does not have security performance, once the burglar use thin hard object by draw, hook lock core or additional simultaneously twisting resistance, make pellet shot from a slingshot be in the enable possition and just lockset can be opened.98236169.6 patent a kind of patent No. is disclosed in addition is, its name is called " a kind of cylinder lock ", the characteristics of this lock are lock core is separated into two sections or three sections, but the structure of this lock is only separated and is not isolated, promptly in the segmentation lock core of lock body, do not install dividing plate, so just can not fine strick precaution robber open lockset with tooth bar or the moving lockaid gun of electroshock.

Three, summary of the invention:

The purpose of this utility model be according to Principles of Network in length and breadth diversification designed a kind of have can prevent drawing, anti-hook, anti-ly turn round, the comprehensive a kind of novel anti-theft tapered end of anti-technical unlocking of performance.

The utility model mainly is made up of tapered end housing, lock core, shift fork, pellet shot from a slingshot or shell fragment, it is characterized in that in the tapered end housing lock core by dividing plate carry out list every or two, compound lock core single every constituting; And the pellet shot from a slingshot in the lock core can be transversely arranged according to the shape difference of lockhole; The lock core section is provided with dividing plate in addition, and the lock core section is not exposed, therefore can take precautions against effectively the robber with thin hard object draw, hook, twistlock core and use state-of-the-art technology means unlatching locksets such as Unlocking gun and electronic electromagnetic shaker.

Five, the specific embodiment:

Below in conjunction with accompanying drawing the utility model is described in further detail:

Shown in accompanying drawing 1-4, the utility model comprises that tapered end housing (1), rotating lock core (2), shift fork (3), pellet shot from a slingshot (4) or shell fragment (5) form, lock core (2) section that it is characterized in that tapered end housing (1) is provided with dividing plate (6), and lock core (2) section is not exposed; Be provided with on the lock core (2) in tapered end housing (1) this dividing plate of dividing plate (6) (6) can to lock core (2) single every or two every constituting single, compound hidden isolation; Lock core is free to rotate, and the pellet shot from a slingshot (4) in the lock core (2) both can vertically have been arranged according to the shape difference of lockhole (7), again can be transversely arranged; Lock core (2) is connected with shift fork (3), when using the key that is complementary with lock core (2) to insert lock core (2) by difform lockhole (7), lock core (2) drives shift fork (3) and rotates, make the normal unlatching of lock core (2), when opening with thin hard object, horizontal pellet shot from a slingshot (4) of cause or dividing plate (6) can effectively hinder master key and reverse, and therefore can not open.

Claims (1)

1, a kind of novel anti-theft tapered end, mainly formed, be it is characterized in that by tapered end housing (1), rotating lock core (2), shift fork (3), pellet shot from a slingshot (4) or shell fragment (5): the lock core (2) in tapered end housing (1) by dividing plate (6) carry out list every or two every constituting single, compound lock core; And the pellet shot from a slingshot (4) in the lock core (2) can be transversely arranged according to the difference of lockhole (7) shape; Lock core (2) section of tapered end housing (1) is provided with dividing plate (6) in addition, and lock core (2) section is not exposed.
