Abstract

The utility model relates to an improved antitheft lock which comprises a mechanical lock head, a cipher lock, and a lock body. The mechanical lock head matched with a spring is arranged in a sleeve barrel which is provided with scales, A guide slot of the mechanical lock head is cooperated with a guide rail which is arranged in the sleeve barrel. The sleeve barrel which is provided with scales and a clamping plate are connected together via a screw rod. A rotating rod of the mechanical lock head, which extends from a center hole of the clamping plate, is fixedly connected with an opening mechanism of the cipher lock which is provided with a blocking component via a connecting device, and the cipher lock is connected with the opening mechanism of the lock body. The utility model has the antitheft performances of a mechanical antitheft lock and the cipher lock simultaneously, the structure is reasonable, and the operation is flexible.

Description

Improved theftproof lock

The utility model belongs to the improvement of theftproof lock, particularly a kind of improved theftproof lock.

Present widely used theftproof lock is divided into mechanical anti-theft lock, puzzle theft-proof lock and electronic safety lock substantially.

Mechanical anti-theft lock is generally opened lock with key.Do not having under the situation of key and since mechanical anti-theft lock adopted anti-pound, technology such as anti-drilling, pick-proof, be difficult for opening of destroyed property.But utilization master key or other technological means but can be opened lock, make its forfeiture anti-theft feature.

Puzzle theft-proof lock, owing to adopted the password of a large amount of various combination modes, the possibility of decryption is minimum, is difficult to unblank by technological means, but very easily is opened under cipher anti theft the has been locked in destroyed destructive means such as knob, finally loses anti-theft feature.

Electronic safety lock has higher theftproof, when the cost height, and complex manufacturing, and be subjected to the influence of electronic component, unstable properties, fault rate height.So the mechanical unlocking device that standing usefulness is emergent, and the setting of this device has reduced its theftproof performance, thereby present electronic safety lock is difficult to promote.

The purpose of this utility model is to provide a kind of improved theftproof lock, mechanical anti-theft lock and puzzle theft-proof lock advantage are separately combined together, both had that mechanical anti-theft lock anti-is pounded, the technical performance of anti-drilling, pick-proof, the performance of passing through password unlocking that has puzzle theft-proof lock again, the comprehensive theft performance is good, and production technology is uncomplicated.

The purpose of this utility model is achieved in that a kind of improved theftproof lock, comprise mechanical lock tapered end, coded lock and lock body, have and be installed with in the sleeve of dial and compress the mechanical lock tapered end that spring matches, guide rail in the guide groove of mechanical lock tapered end and the sleeve matches, the sleeve and the clamping plate that will have dial by screw rod are fixed together, the bull stick of the mechanical lock tapered end that stretches out from the clamping plate centre bore is fixed together by linkage and the opening mechanism that has the coded lock of block piece, and the opening mechanism of coded lock and lock body links.

Survivable characteristics such as the utility model utilizes mechanical anti-theft lock anti-ly pounds, anti-drilling, pick-proof are arranged on the outside with the lock core of mechanical anti-theft lock, utilize the high characteristic of anti-skilled unlocking performance of coded lock that it is arranged on inside, and it is destroyed that it is difficult for.When unblanking, key is inserted in the mechanical lock by the method rotation of generally opening coded lock, with all passwords with after the scale on the dial is corresponding, block piece no longer works, then the mechanical lock tapered end is advanced along slide rail, the opening mechanism that drives coded lock simultaneously advances, and the opening mechanism of coded lock opening mechanism and lock body is connected as a single entity, and opens lock body by the method for opening the standard machinery theftproof lock again.When shutting, lock body is locked, the coded lock opening mechanism is separated with block piece with lock body, under the effect of spring, make mechanical anti-theft lock tapered end return, extract key then out by the method for standard machinery theftproof lock.

Owing to adopted such scheme,, or, do not had correct password to open with master key and technological means and means of destruction even use key steathily.So theftproof performance of the present utility model is higher than other theftproof lock far away.The utility model is simple in structure, flexible operation, and reliability is very high, and is applied widely, is easy to promote.
