Description
Affiliated technical field
The utility model relates to a kind of tapered end locking mechanism.
Background technology
Existing tapered end locking mechanism, all comprise tapered end and be assemblied in locking plate, lock core in the tapered end that also be provided with lock latch jack in the tapered end, lock core drives the locking plate forward or reverse, make the groove engaging on locking plate and the lock bolt or separate, thus the purpose that reaches locking, unblanks.This tapered end lock uint, its assembly structure is simple and crude, and reliability is low, theftproof performance is poor.
Summary of the invention
Simple and crude in order to overcome the structure that common tapered end locking mechanism exists in the prior art, reliability is low, the problem of theftproof performance difference, the utility model provides a kind of tapered end locking mechanism, this tapered end locking mechanism simple in structure, easy to assembly, sealed reliable, theftproof performance is strong.
The technical scheme that its technical problem that solves the utility model adopts is: comprise lock body and lock core, lock body is provided with the lock latch jack that matches with lock bolt, have lock slots on the lock bolt, in the lock body of lock latch jack both sides, respectively be provided with chute vertical with lock latch jack and that be communicated with, roller is set in the chute, the lock core shaft of lock core links to each other with dial, and the arm of dialling of dial matches with roller.
Be provided with reduction torsion spring in lock core shaft, the arm of dialling of dial is provided with the propelling inclined-plane.
Lock core shaft and dial plug.
The utility model is by above-mentioned specific design, mode with the roller locking, effectively improved the reliability of lockset locking, had the advantage of simple and compact for structure, easy to assembly, good reliability, good anti-theft effect, be particularly suitable in all kinds of stripe shape locksets, applying.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
The specific embodiment
As shown in the figure, the utility model comprises lock body 1 and lock core 2, lock body 1 is provided with the lock latch jack 4 that matches with lock bolt 3, the bottom of lock latch jack 4 is provided with spring 14 and top cap 15, have lock slots 11 on the lock bolt 3, in the lock body 1 of lock latch jack 4 both sides, respectively be provided with chute 6 vertical with lock latch jack 4 and that be communicated with, roller 7 is set in the chute 6, the lock core shaft 8 of lock core 2 links to each other with dial 9, the end of lock core shaft 8 can be to be plugged in the dial 9, be provided with reduction torsion spring 12 in lock core shaft 8, the arm 10 of dialling of dial 9 matches with roller 7, and the arm 10 of dialling of dial 9 is provided with propelling inclined-plane 13.During locking, insert lock bolt 1 and rotational lock core 2, lock core shaft 8 drives dials 9 and also rotates simultaneously, dial 9 dial arm 10 by in the lock slots 11 that advances inclined-plane 13 roller 7 is advanced on the lock bolt 3 that inserts in the lock latch jacks 4, extract key after lock bolt 3 locked.When unblanking, lock core 2, lock core shaft 8 and dial 9 backward rotation, the arm 10 of dialling of dial 9 separates with roller 7, pushes roller 7 open to both sides when extracting lock bolt 1, and lock is opened.
