Abstract
The utility model relates to a breakable lock which comprises a lock body (1), a front lock core (2), a rear lock core (3) and a shifting fork (4). The front lock core (2) and the rear lock core (3) are symmetrically arranged on the front side and the rear side inside the lock body, the middle of the lock body (1) is provided with a notch, the shifting fork (4) is arranged in the notch and matched with the front lock core (2) and the rear lock core (3), and a plurality of elastic body mechanisms are arranged among the front lock core (2), the rear lock core (3) and a lock body (1). The breakable lock is characterized in that the peripheries of the lock body (1) and the front lock core (2) are provided with an annular groove, a connecting part is reserved at the center of the annular groove, the part of the connecting part on the front lock core (2) is named as a connecting part I (5), and the part of the connecting part on the lock body (1) is named as a connecting part II (6). By means of the breakable lock, thieves cannot easily clamp locks outside the doors and pull the locks out or destroy the locks, thereby avoiding stealing.
Description
Technical field
The utility model relates to a kind of tapered end, especially relates to a kind of tapered end that breaks, and belongs 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 purpose of the utility model 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 purpose of the utility model is achieved in that
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 beneficial effect of the utility model is:
The utility model 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.
