Description

Planar clutch formula anti-theft puzzle lock

The utility model relates to a kind of planar clutch formula anti-theft puzzle lock that is used to be installed on combination lock, strongbox, safety cabinet, secret chamber, the national treasury.

Coded lock commonly used on the strongbox generally adopts the chute structure at present, during use, aims at the password line of rabbet joint that this lock is selected for use earlier, uses key operated then.This coded lock exists the deficiency of some aspect, is difficult for taking good care of or is easily lost as key, and the line of rabbet joint is opened password and easily measured by instrument or penetrated by other people, does not reach desirable anti-theft effect again so use not too to make things convenient for.

The purpose of this utility model is will provide a kind of planar clutch or anti-theft puzzle lock at the deficiency of above-mentioned technology existence, adopt irregular some toothing, it neither needs key operated, is difficult for again being measured the unlatching password by instrument, easy to use, have desirable theftproof performance.

The purpose of this utility model is achieved in that a kind of planar clutch formula anti-theft puzzle lock, it by lock body and lock body after plate connect and to constitute, it mainly is on the back side of plate behind the lock body dead bolt to be housed, clutch-plate is housed in the lock body die cavity and does not plan gear, the clutch-plate frontal plane contacts with the rear end planar slide of irregular gear, plate movably contacts behind clutch-plate back plane and the lock body, and the back axle head is equipped with gear, the tooth bar tabling on gear and the dead bolt.The bullet that has on the plate contact plane behind the irregular tooth of irregular gear rear end and the lock body pellet shot from a slingshot of packing in the hole contact, the pellet shot from a slingshot rear end contacts with spring, the lock body external surface number of being equipped with chip set, closely cooperate with the front end face of not planning gear and to connect, number sheet surface is provided with digital calibration, play the location and recognize the note effect, what be positioned at lock body appearance front dials handle and clutch front end axle by screw attachment, and plate is fixed on the sealed body medial surface behind the lock body.

The utility model modern design, compact conformation need not be furnished with key, and number can be set arbitrarily, and the number location of setting is difficult for by other people identification and opens, and has desirable cipher anti theft performance.
