Abstract

The utility model belongs to a lock, the safety of which is controlled by electric signals, which is composed of an electromagnet 1 fixed on a lock body or the accessory body of the lock, a moveable iron core 2 of the electromagnet used as an insurance fixture block, a guide hole 3 through which the movable iron core 2 can penetrate and a bayonet 4 arranged on a lock bolt; besides, the guide hole 3 is arranged on the lock body or the accessory body of the lock. The movement of the movable iron core 2 of the electromagnet is controlled by the electric signals in order to block or release the lock bolt, and the movable iron core 2 of the electromagnet can penetrate through the guide hole 3 and the bayonet 4; besides, the purpose of keeping the safety is realized by the electric control.

Description

Electroniagnetic safety lock

The utility model is the lock about a kind of automatically controlled insurance.

At present, the safety lock of a lot of various samples is arranged, they adopt the insurance institution of pure machinery mostly.Such as the insurance office on the built-in lock, the insurance office that the key turns that the dual fail-safe built-in lock passes through is closed.The purpose of these insurance offices is that its dead bolt receipts are not returned after insuring, thereby lock is not opened.Because the insurance office of these locks is mechanical, need to operate with manpower, these locks are just little suitable concerning some doors that need to control automatically like this.The utility model designs in order to address this problem just.Its feature is the insurance office that electricity consumption comes control lock.

The purpose of this utility model provides a kind of lock of controlling its insurance office with the signal of telecommunication.So that it can adapt to the needs that control environment automatically.

Generally, the operating principle of the insurance office of lock is when dead bolt stretches out, and has a fixture block to block dead bolt its receipts are not gone back.The action of controlling this fixture block just can make its insurance office open or close.It in the utility model the action of controlling this fixture block by electromagnet.This fixture block is the movable core of electromagnet, and when switching on to electromagnet, because the effect of magnetic force, this fixture block is that the movable core of electromagnet is sucked in the electromagnet; When not switching on to electromagnet, owing to there is not the effect of magnetic force, this fixture block stretches out electromagnet, thereby it is machine-operated to have realized controlling insurance of the present utility model with the signal of telecommunication.

As shown in Figure 1, the utility model has been installed an electromagnet 1 on the attached body of lock; Opened a bayonet socket 4 at the head of dead bolt; One and bayonet socket 4 corresponding guide holes 3 on attached body, have also been opened; The movable core 2 of electromagnet 1 can insert in the bayonet socket 4 by guide hole 3.Dead bolt puts in the attached body under the elastic force effect of lock self when locking a door, because the effect on inclined-plane and the pressure of dead bolt, movable core 2 overcomes the elastic force of electromagnet 1 inner spring and regains in the electromagnet 1.After in dead bolt all stretches into attached body, bayonet socket 4 just in time aligns with guide hole 3, at this moment movable core stretches out electromagnet 1 and inserts in the bayonet socket 4 under the work of elastic force, so just dead bolt has been stuck in the attached body, no matter the wrench on the lock body 5 how also can't regain dead bolt by the moving dead bolt of plate.This lock also just has been insured.Give electromagnet 1 energising when unblanking, movable core 2 is just sucked back and can not insert in the bayonet socket 4 on the dead bolt, and dead bolt just is not stuck in the attached body like this.Down moving at the plate of wrench 5, dead bolt is with regard in the recoverable lock body, thereby lock is opened.

As shown in Figure 2, this is another form of the present utility model, and electromagnet 1 is installed on the lock body, and movable core 2 can block the bayonet socket 4 of dead bolt by the guide hole on the lock body 3.Its operating principle is big to identical with operating principle shown in Figure 1.Different is before locking a door, and movable core 2 is sucked back must for electromagnet 1 energising, so that can allow dead bolt regain in the process of locking a door.Lock behind the door, dead bolt stretches into attached body fully, at this moment gives electromagnet 1 outage, and movable core 2 stretches out the bayonet socket 4 that blocks dead bolt, and dead bolt is blocked, and the dead bolt withdrawal can't be reached the purpose of insurance when pulling wrench 5.

Claims

1, the lock of its insurance office of a kind of electricity consumption signal controlling is characterized in that its insurance office is made up of the bayonet socket 4 of electromagnet 1, movable core 2, guide hole 3, dead bolt.

2, lock according to claim 1 is characterized in that its electromagnet is fixed on the attached body of lock.Have the guide hole 3 that allows movable core 2 pass on the attached body.

3, lock according to claim 1 is characterized in that its electromagnet is fixed on the lock body of lock.Have the guide hole 3 that allows movable core 2 pass on the lock body.
