Abstract

The utility model relates to the field of a lockset, more specifically a theftproof lock which is provided with a plurality of linkage lock cores. The utility model comprises a lock body and at least two lock cores in the lock body, wherein the lock cores are arranged in parallel and the blind end of each lock core is fixedly connected with gears which have the same shaft as the shaft of the lock cores. The adjacent gears are engaged, and all gears which are orderly connected are distributed in a double-head line type or a sealed annular shape. The utility model is provided with the lock cores which are respectively matched with one key, the linkage among the gears is achieved by any key after all keys are inserted into relative lock cores so that the lock is opened and has a good theftproof effect. The lock is widely applied, and is used for various padlocks or embedded locks for a door. The lock is particularly and suitably used as various locksets of strong rooms, safe doors and the safes for confidential departments and can be only opened by a plurality of keys held by many people.

Description

Theftproof lock

Technical field

The utility model relates to a kind of lockset, specifically a kind of theftproof lock that is provided with a plurality of interlock lock cores.

Background technology

At present, in the life or the lockset of selling on the market generally all be single core-locking type, the key mutual opening rate of this lockset is very high, just can open easily even without the simple tool for destroying of key utilization, more how anti-theft effect.Though the single core lockset that also has has increased the function of mechanical turntable type password, for being meant to the people of this lock of pirate of the open, opening it does not need too big strength yet, the anti-person of low position of the only anti-gentleman of its anti-theft effect.

The utility model content

Technical problem to be solved in the utility model is that a kind of multicore theftproof lock will be provided, and every lock core all is furnished with a key, has only after all keys all insert corresponding lock core, twists arbitrary handle and can realize interlock between gear, and lock is opened.Its key mutual opening rate reduces widely; If there be not this lock of pirate of the open under the situation of key, its difficulty is higher, so the anti-theft effect of this lock improves widely.

It is to be achieved by following technical scheme that the utility model will solve above-mentioned technical problem: a kind of theftproof lock, comprise lock body and at least two lock cores that are positioned at lock body, described lock core be arranged in parallel, and each lock core is fixedly connected with gear with lock pin coaxial in its cecum, meshes between adjacent gear.

All gears link to each other successively and are the distribution of double end line style.

As improvement of the present utility model, described lock core has four or more even number, and lock core distributes in lock body in the form of a ring, meshes between adjacent gear, and all gears link to each other successively and are the closed circular distribution.

The theftproof lock of said structure provided by the utility model, owing to adopt multicore interlock scheme, each lock core all is furnished with a key, and connect firmly between lock core and gear, have only every key be inserted into could realize in the corresponding lock core interlock, therefore it is indispensable to want a lock to open many keys, and its key mutual opening rate reduces widely, so good anti-theft effect.

The utility model scope of application is extensive, can be used for upward embedded lock of various padlocks or door.This lock especially is suitable for various strong-rooms, security door, the safety cabinet lockset as confidential departments, and many keys that need many people to hold possess Shi Caineng simultaneously and open.

Machine will be described in further detail with specific embodiment in conjunction with the accompanying drawings under the utility model.
