Abstract
The invention relates to a lock head capable of being broken. The lock head comprises a lock head body (1), a front lock cylinder (2), a rear lock cylinder (3) and a shifting fork (4), wherein the front lock cylinder (2) and the rear lock cylinder (3) are symmetrically arranged at the front side and the rear side in the lock head body, a notch is arranged at the middle part of the lock head body (1), the shifting fork (4) is arranged in the notch and matched with the front lock cylinder (2) and the rear lock cylinder (3), and a plurality of groups of spring mechanisms are arranged among the front lock cylinder (2), the rear lock cylinder (3) and the lock head body (1). The lock head is characterized in that the front lock cylinder (2) is arranged, a ring slot is arranged at the peripheries of the lock head body and the front lock cylinder, a connecting part is reserved at the center of the ring slot, a connecting part on the front cylinder (2) is called as the connecting part I (5), and a connecting part on the lock head body (1) is called as the connecting part II (6). According to the lock head capable of being broken, a thief cannot clamp the lock head outside a door easily so as to avoid pulling or damaging the lock head so as to prevent the stealing.
Description
Technical field
The present invention relates to a kind of tapered end, especially relate to a kind of tapered end that breaks, belong to the door lock field.
Background technology
The crucial general position of lock is a tapered end; Because the needs that tapered end is installed, existing mortise lock comprises tapered end, and the two ends of tapered end are equipped with lock core; Tapered end passes a body when mounted; Its two ends lay respectively at the outside and the inside of door, and the thief usually can tool using will be positioned at the tapered end clamping of face outdoors easily and then tapered end extracted or destroyed, and successfully commit theft.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of cannot be easily with being positioned at the broken tapered end that the tapered end clamping of face is outdoors extracted tapered end or destroy then.
The objective of the invention is to realize like this:
A kind of tapered end that breaks comprises tapered end, preceding lock core, rear lock core and shift fork, and preceding lock core and rear lock core are symmetrically arranged in the inner both sides, front and back of tapered end; The middle part of said tapered end is provided with breach; Said shift fork is installed in the breach and with preceding lock core, rear lock core and matches, and is provided with many group billiard mechanisms between said preceding lock core, rear lock core and the tapered end, and every group of billiard mechanism comprises pellet shot from a slingshot, tack pellet shot from a slingshot and pellet shot from a slingshot spring down; Said tapered end is provided with annular groove with the periphery of preceding lock core; Connecting portion is left at the center of annular groove, and the connecting portion before being positioned on the lock core is called connecting portion I, and the connecting portion that is positioned on the tapered end is called connecting portion II.
Said annular groove is divided into tapered end leading portion and tapered end back segment with tapered end; Said annular groove is divided into lock core leading portion and lock core back segment with preceding lock core; Said lock core leading portion links to each other through connecting portion I with the lock core back segment, and said tapered end leading portion links to each other through connecting portion II with the tapered end back segment.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention is because connecting portion I and connecting portion II intensity are lower; Make that tool using will the tapered end of face strikes off the thief with being positioned at outdoors easily when committing theft; Lock core leading portion and tapered end leading portion fall down, and only remain the lock core back segment and the tapered end back segment is exposed to face outdoors, and clamping device is difficult to the clamping stability under loading; The thief cannot extract tapered end or destroy then being positioned at the tapered end clamping of face outdoors easily, prevents to commit theft.

The specific embodiment
Referring to Fig. 1, the present invention relates to a kind of tapered end that breaks, comprise tapered end 1, preceding lock core 2, rear lock core 3 and shift fork 4; Before lock core 2 be symmetrically arranged in the inner both sides, front and back of tapered end with rear lock core 3, the middle part of said tapered end 1 is provided with breach, said shift fork 4 is installed in the breach and matches with preceding lock core 2, rear lock core 3; Be provided with many group billiard mechanisms before said between lock core 2, rear lock core 3 and the tapered end 1; Every group of billiard mechanism comprises pellet shot from a slingshot, tack pellet shot from a slingshot and pellet shot from a slingshot spring down, mills out annular groove at tapered end 1 with the periphery of preceding lock core 2 with milling cutter, and connecting portion is left at the center of annular groove; Connecting portion before being positioned on the lock core 2 is called connecting portion I5; The connecting portion that is positioned on the tapered end 1 is called connecting portion II6, and said annular groove is divided into tapered end leading portion 11 and tapered end back segment 12 with tapered end 1, and said annular groove is divided into lock core leading portion 21 and lock core back segment 22 with preceding lock core 2; Said lock core leading portion 21 links to each other through connecting portion I5 with lock core back segment 22, and said tapered end leading portion 11 links to each other through connecting portion II6 with tapered end back segment 12.Because connecting portion I5 and connecting portion II6 intensity are lower; Make that tool using will the tapered end of face strikes off the thief with being positioned at outdoors easily when committing theft; Lock core leading portion 21 falls down with tapered end leading portion 11, only remains lock core back segment 22 and tapered end back segment 12 is exposed to face outdoors, and clamping device is difficult to the clamping stability under loading; The thief cannot extract tapered end or destroy then being positioned at the tapered end clamping of face outdoors easily, prevents to commit theft.
