Abstract

The utility model relates to an anti-theft puzzle lock which is mainly provided with a controlling rotary disk, a controlling main shaft, a guiding positioning disk, a rotary nut, and an opening handle. The controlling main shaft is driven by the rotary nut to carry out linear motion to and fro under the constraint of the guiding positioning disk and under the condition that a contact head which is arranged on the controlling main shaft is aligned to a notch which is made in the controlling rotary plate, and the purpose that the opening and the rotation of a handle shaft are controlled is achieved. The telescopic effect of a lock bolt is realized. The puzzle performance of the lock is high. The high intelligent opening is prevented. The failure rate is zero, the puzzle is set automatically, and no key is needed. Cold stamping and hot extrusion are main work technologies, the machine work is subsidiary, and the cost of the anti-theft puzzle lock is seventy percent of the cost of an ordinary anti-theft door lock.

Description

Anti-theft puzzle lock

The utility model relates to a kind of antitheft secret lockset in the fixed buildings field.

Present widely used coded lock, its scrambler only starts to control making usefulness, is the part of lockset, and three garden shape control strips have 2 to be to utilize the precompression of spring to realize positioning function, when aligning password, be easy to generate inconsistent phenomenon, the user need align again, if its structure is carried out general Study, just can find out the breach on the control strip, pairing password number on dial, deciphering causes scrambler generally not promote naturally.

Coded lock on portable, hand push combination lock, though it is to utilize setting code to determine the tram of control part, reach the purpose of control locking bolt motion, yet its structure is too simple, rely on the active force of spring, the motion of promotion locking bolt, the tram of positioning control part, so, produce inconsistent phenomenon when aligning password, fault rate height during use, it is also easy to decipher, and this lock is to satisfy the many-sided requirement of user.

For the cylinder lock that uses in the market, also be that lockhole is blocked by the people easily by key-operated coded lock in fact.More than various locksets can't resist various high intelligent crimes.

The purpose of this utility model is to be zero for the user provides fault rate, and password can set up on their own, and technical unlocking is difficult for, and need not key, very high, the with low cost lockset of anti-intelligence theft performance.

The technical solution of the utility model is achieved in that this anti-theft puzzle lock, comprise fixed disk and dial, dial connects the spline hook bolt, flexibly connect with the control rotating disk again, be evenly distributed with 2-6 control rotating disk in the fixed disk, the control rotating disk is between core shell and core housing-plate, the periphery one or both sides of control rotating disk are provided with 3 with upper groove and 1 breach, being equipped with on the Handle axis can the inside and outside control main shaft that moves, the control outer rim is provided with the contact of 2-6 projection, its end outer rim that links to each other with driving lever is provided with 4 guiding stop head, and the guiding stop head embeds in the guide-localization dish.Contact can fall in the breach of control rotating disk.Garden shape fixed disk guiding stop head embeds in the guide-localization dish.Contact can fall in the breach of control rotating disk.Handle axis is equipped with in garden shape fixed disk central authorities, is provided with lead sleeve between Handle axis and the control main shaft, and there is the plumbous case of a sealing lock body fixed disk inboard.Can replace controlling rotating disk with controll block, controll block is provided with driving rack.

The utility model has the advantages that: processing technology is simple, the process equipment generalization, and cost is low, does not need key unlocking, prevents high intelligent opening.

The utility model will be further described below in conjunction with accompanying drawing:
