Abstract

Multi -cylinder lock comprises the lock core that a plurality of lock points are different to arrange into circularly, the lock core jack is all outside, and mutual contained angle homogeneous phase etc. Each lock core afterbody all are equipped with the external gear, and all external gear overcoats have an interior gear turntable, and the carousel bottom is equipped with a push rod, rather than many supporting keys, also arrange into circularly, its thread form limit is all outside, mutual contained angle homogeneous phase etc, each key head all is equipped with the external gear, there is an interior gear turntable at all external gear overcoats, after in the key of will forming a complete set inserts the jack of each lock core according to the design position, press the outer interior gear turntable of clockwise screw key head, it just will promote each key head external gear, each key, each lock core, each lock core afterbody external gear and interior gear turntable and push rod be the synchronous revolution simultaneously, when rotating 90 o'clock, the push rod will stimulate the spring bolt and retract from the jack, multi -cylinder lock is opened, if opposite spin, then can realize multiple insurance, then can't not explain it if there is supporting key, so be safety precautions's tool to lock.

Description

Multi-cylinder lock

Technical field:

This patent belongs to field of lockset.This lockset is made up of multiple lock different lock cores of point, many supporting keys synchronous rotary simultaneously can open, otherwise cannot crack, therefore be the lockset of most security insurance.

Background technology:

Lockset of all times is constantly brought forth new ideas through over the past thousands of years improvement, and theftproof performance is much improved, but because constituting by a lock core, is often cracked, it is impossible to guarantee safety.

Summary of the invention:

In order to solve the unsafe problems that traditional single lockset is easily cracked, the technical scheme of this patent design is: it is the lockset being made up of multiple lock different lock cores of point, each lock core is arranged in circle, lock core jack is all outside, between jack, angle is all equal, and each lock core afterbody is equipped with external gear, and each external gear is independent of each other, outside all external gears, it is cased with an internal gear rotating disk, bottom rotating disk, is provided with a push rod；Many the keys supporting with Multi-cylinder lock are also arranged in circle, and the thread form limit of key is all outside, and its mutual angle is all equal, and the head of each key is equipped with external gear, and each external gear is also independent of each other, and is also cased with an internal gear rotating disk outside all external gears；Many keys are inserted by design orientation after in the jack of Multi-cylinder lock, rotating the internal gear rotating disk of key head, it will promote each key head external gear, each key, each lock core, the external gear of each lock core afterbody and the internal gear rotating disk outside it and push rod synchronous rotary simultaneously.

Accompanying drawing illustrates: the existing cylinder lock set to be made up of three lock cores.

Detailed description of the invention:

Three supporting keys are inserted by design orientation after in the jack of three lock cores, front internal gear rotating disk (1) is rotated in the direction of the clock, it will promote the external gear (2) of three key heads, three keys (3), three lock cores (4), the external gear (5) of three lock core afterbodys and rear internal gear rotating disk (6) and push rod (7) synchronous rotary simultaneously, when rotating to 90 °, push rod (7) pulls on dead bolt and retracts from jack, thus three core locks are opened.If by front internal gear rotating disk counter rotation, then three insurances can be realized.

Multi-cylinder lock only can be opened when all lock cores synchronous rotary simultaneously, so when without matched key, it is impossible for will cracking it, therefore its security insurance coefficient is the highest, and traditional single core lock cannot compare with it.And the lock point many (having tens at least) of Multi-cylinder lock, therefore that fearness makes more than one hundred million, also all respectively has uniqueness, will not occur that single lock can open the generation of several lock phenomenons like that with a key.

Claims (1)

1. Multi-cylinder lock, it is characterized in that: it is the lockset being made up of multiple lock different lock cores of point, each lock core is arranged in circle, lock core jack is all outside, between jack, angle is all equal, and each lock core afterbody is equipped with external gear, and each external gear is independent of each other, outside all external gears, it is cased with an internal gear rotating disk, bottom rotating disk, is provided with a push rod；Many the keys supporting with Multi-cylinder lock are also arranged in circle, and the thread form limit of key is all outside, and its mutual angle is all equal, and the head of each key is equipped with external gear, and each external gear is also independent of each other, and is also cased with an internal gear rotating disk outside all external gears；Many keys are inserted by design orientation after in the jack of Multi-cylinder lock, rotating the internal gear rotating disk of key head, it will promote each key head external gear, each key, each lock core, the external gear of each lock core afterbody and the internal gear rotating disk outside it and push rod synchronous rotary simultaneously.
