The bottom of lock body 1 is provided with another dead bolt 8, and the correspondence position of dead bolt box 2 is provided with the groove 12 of dead bolt 8 correspondence therewith, for holding this dead bolt.This dead bolt 8 is dead bolt for subsequent use, does not use and also can reach effect of locking a door, and this dead bolt 8 is fixed on the inside of lock body 1 under normal circumstances.
When door is in open mode, dead bolt 4 is in primary importance, the inside of the normal indentation lock body 1 of dead bolt 4, when the door closes, dead bolt 4 moves to the second place by primary importance, namely, under the interaction of the first magnet 3 and the second magnet 10, dead bolt 4 ejects from lock body 1 inside under magnetic force attracts, and it is inner to embed dead bolt box 2, complete action of locking a door, now, pull bar 5 ejects with the first magnet 3, and back-moving spring 6 moves to dead bolt box 2 direction the second end being compressed into pull bar 5 simultaneously.
When door is opened by needs, by stirring shift fork 7, the pull bar drive end 70 of shift fork 7 drives back-moving spring 6 to compress to the direction of pull bar second end 52 further, thus drive pull bar 5 to move to the inner direction contrary with dead bolt box 2 of lock body 1, overcoming magnetic pull makes dead bolt 4 indentation return back to primary importance, completes door opening action, now, decontrol shift fork, back-moving spring 6 stretches out.
As shown in Figure 6, the first side wall 101 of lock body 1 is provided with the through hole passed through for dead bolt 4, dead bolt box 1 is provided with holding tank 12 in the position corresponding with through hole, the volume of holding tank 12 is suitable for the volume of dead bolt 4, for holding dead bolt 4, stopper sheet 9 is provided with the opening 91 passed through for dead bolt 4 in the position corresponding with holding tank.Under the mutual attractive force effect of the first magnet 3 and the second magnet 10, dead bolt 4 can stretch out through hole through the opening of stopper sheet 9 and embed in holding tank 12, completes action of locking a door.
As shown in Figures 1 and 5, be provided with the second magnet container cavity 21, second magnet container cavity 21 in dead bolt box 2 and have opening 22 on stopper sheet 9 side, opening 22 is less than the profile of the second magnet 10, and opening 22 surface coverage has silencing block 11.
The top of dead bolt box 2 offers installing hole 14, second magnet 10 is slided by installing hole 14 and inserts the second magnet container cavity 21 inside of dead bolt box 2 inside, the side opening of the second magnet 10 is provided with spacing hole 15, and it is spacing in the second magnet container cavity 21 of dead bolt box 2 by means of a pin.
Preferably, the surrounding of described first magnet and/or the surrounding of described second magnet are all filled with macromolecular material.
The surrounding of inner first magnet 3 of dead bolt 4 and the surrounding of inner second magnet 10 of dead bolt box 2 are all filled with macromolecular material, protect magnet.
In the present embodiment, the first magnet 3 is cylinder form, and the second magnet 10 is rectangular shape.
Dead bolt box 2 is made of plastics, and the plastics of dead bolt box 2 and dead bolt 4 are selected from POM, fluoroplastics, nylon, hard resin, one of PE, ABS.
As shown in Figure 3, another end of shift fork 7 is provided with pusher dog 71, and pusher dog 71 is connected with shift fork body pivot, and shift fork 7 offers square through hole 72, facilitates door handle to stretch into and stirs pusher dog, by stirring pusher dog 71, shift fork body can be driven to move.
Below operating principle of the present invention is further explained:
Primary importance when dead bolt 4 has an indentation lock body 1 and stretch out lock body 1 and embed the second place of dead bolt box 2.
When door is in open mode, dead bolt 4 is in primary importance, the inside of the normal indentation lock body 1 of dead bolt 4, when the door closes, dead bolt 4 moves to the second place by primary importance, namely, under the interaction of the first magnet 3 and the second magnet 10, dead bolt 4 ejects from lock body 1 inside under magnetic force attracts, and it is inner to embed dead bolt box 2, complete action of locking a door, now, pull bar 5 ejects with the first magnet 3, and back-moving spring 6 moves to dead bolt box 2 direction the second end being compressed into pull bar 5 simultaneously.During owing to locking a door, be completed by the magnetic force of the first magnet 3 and the second magnet 10, and set up silencing block in the outside of the second magnet, therefore, at closing time, almost without any sound, reach quiet object.
When door is opened by needs, by stirring shift fork 7, shift fork 7 drives back-moving spring 6 to compress to the direction contrary with dead bolt box 2 further, thus drive pull bar 5 to move to the inner direction contrary with dead bolt box 2 of lock body 1, dead bolt 4 to primary importance, completes door opening action by second site reversion, now, decontrol shift fork, back-moving spring 6 stretches out.
Lock body 1 is provided with the through hole passed through for dead bolt 4, dead bolt box 1 is provided with holding tank 12 in the position corresponding with through hole, the volume of holding tank 12 is slightly larger than the volume of dead bolt 4, under the interaction of the first magnet 3 and the second magnet 10, dead bolt 4 can stretch out through hole and embed in holding tank 12, completes action of locking a door.
Advantage of the present invention is as described below:
Magnet is set up on the basis of common door lock, the back-moving spring of common door lock is arranged on the other end of pull bar, to close the door action by means of only the enabling changing the position of back-moving spring and namely can realize the quiet lock of magnetic force, structure is simple, cost of manufacture is low, does not increase cost of production relative to common door lock.
The two poles of the earth of two blocks of magnet are not directly mounted opposite, and in enabling situation, are not easy to produce interaction, namely can not affect the application life of magnet, add the application life of the quiet lock of whole magnetic force.
Add silencing block, reduce the noise that door lock produces when closed further, magnetic key operated lock of the present invention is being ejected by attraction dead bolt at closing time, adds the effect of silencing block.Close the door when opening the door and can't hear any noise, add the experience effect of user.
Last it is noted that above-described each embodiment is only for illustration of technical scheme of the present invention, be not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in previous embodiment, or to wherein partly or entirely technical characteristic carry out equivalent replacement; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technical scheme.
