Description

Complete anti-magnetic control lock

The utility model relates to a kind of lockset.What be particularly related to is a kind of magnetic control lock that utilizes magnetic principles to come locking and unlatching.

Chinese patent CN2185774U, CN2191256 serve as that topic discloses two kinds of magnetic control locks with " digital magnetic code automobile anti-theft lock " and " reflection type magnetic padlock head " respectively, its formation is that movable permanent-magnet steel pellet shot from a slingshot connect that there is a natural attraction between the sexes is symmetrical arranged, during no key, corresponding permanent-magnet steel pellet shot from a slingshot is inhaled mutually and is made movable permanent-magnet steel pellet shot from a slingshot enter the blind hole of lock core automatically, makes lock be in the locking shape.After inserting key, be located in the key body with permanent magnet corresponding settings of permanent-magnet steel pellet shot from a slingshot the permanent-magnet steel pellet shot from a slingshot is scolded the lock core blind hole, make and lock unlatching.Their shortcoming is that the mutual perturbed force of two adjacent groups permanent magnetism pellet shot from a slingshot causes a certain group of incomplete locking phenomenon easily because the physical dimension of lock body limits.Promptly cause locking not sternly, easily opened by mistake again by the key of close coding.

The purpose of this utility model is to overcome the existing worn-out end of above-mentioned magnetic control lock, provide a kind of simple in structure, locking is reliable, preventing decryption, the complete anti-magnetic control lock that the ability that opens by mistake is strong.

The complete anti-magnetic control lock of realizing the utility model purpose comprise lock body, lock core, relatively be located at marble bin that the array on lock body and the lock core cross section is made of dark blind hole and shallow blind hole, be located at the magnetic key that can move to the permanent magnetism pellet shot from a slingshot in its dark blind hole entirely and be provided with permanent magnet corresponding to the permanent magnetism pellet shot from a slingshot in the marble bin, it is characterized in that being provided with the magnetic energy bunch block in the bottom of described shallow blind hole, the suction between described magnetic energy bunch block and the permanent magnetism pellet shot from a slingshot connects power less than on the key permanent magnet and the magnetic force between the permanent magnetism pellet shot from a slingshot.After key detached lock core, the low coverage attraction between the magnetic energy bunch block of the permanent magnetism pellet shot from a slingshot in the marble bin bottom shallow blind hole makes the permanent magnetism pellet shot from a slingshot slide to shallow blind hole and the magnetic energy bunch block is inhaled even mutually, made the reliable locking of lock.Key puts in lock core when unblanking, be distributed in polarity identical (or different) in the key body and the polarity corresponding permanent magnet of permanent magnetism pellet shot from a slingshot and permanent magnetism pellet shot from a slingshot, strong repulsion (or strong gravity) between permanent magnet and the permanent magnetism pellet shot from a slingshot overcomes weak suction between magnetic energy bunch block and the permanent magnetism pellet shot from a slingshot and connects power and the permanent magnetism pellet shot from a slingshot is scolded (or sucking-off) shallow blind hole and made it to place entirely dark blind hole, removes the restriction between lock core and the lock body and lock is opened.

The utility model compared with prior art, its advantage one is because shallow blind hole bottom is provided with magnetic conduction magnetic energy bunch block, makes the locking mode be low coverage magnetic energy boundling and inhales chain closing, and has weakened the interference of the magnetic repulsion between adjacent pellet shot from a slingshot greatly, has guaranteed the reliability of locking; The 2nd, the magnetic energy boundling is inhaled and is connected power less than the magnetic force between key permanent magnet and the permanent magnetism pellet shot from a slingshot, and maximum resistance point is constant, and pellet shot from a slingshot and magnetic energy bunch block distance are the shortest, therefore very easily mate, and open flexibility and reliability and very easily guarantee; The 3rd, in the lock body of same volume, the arrangement that can increase its pellet shot from a slingshot is imitated, and improves size of key, anti-ly opens by mistake, preventing decryption performance height.

Below in conjunction with accompanying drawing the utility model is described in further details.But content of the present utility model is not limited in following embodiment.

Embodiment 1:

As shown in Figure 1, 2, lock body 1, lock core 2 and key 3 are continued to use existing structure form formation.The dark blind hole 4 that constitutes marble bin all is located in the lock body 1, and shallow blind hole 5 correspondences are located in the lock core 2.Magnetic energy bunch block 6 is fixed on the bottom of shallow blind hole.Each marble bin interlaces to being located on the different cross sections.The benefit of doing like this is to make each permanent magnetism pellet shot from a slingshot apart from each other with the magnetic disturbance between reducing.The polarity of described permanent magnetism pellet shot from a

slingshot

7,8,9,10,11,12 is regularly arranged in the same way in the present embodiment, and promptly its N utmost point all is located at towards shallow blind hole direction.The polarity of the

permanent magnet

13,14,15,16,17,18 in the key 3 and the corresponding setting of each permanent magnetism pellet shot from a slingshot constitute and scold the open type lockset entirely.In such cases, one magnetic conduction locking piece 20 can be set at the front end of key 3, when extracting key 3 out, this locking piece 20 and produce magnetic attraction between each permanent magnetism pellet shot from a slingshot of process, if the permanent magnetism pellet shot from a slingshot that does not enter shallow blind hole is arranged, this attraction can play dual locking effect once more with inhaling mutually even with the magnetic energy constriction piece of shallow blind hole bottom in the shallow blind hole on the permanent magnetism pellet shot from a slingshot suction lock core 2.That Fig. 1 provides is lock opening figure.Fig. 3 has provided locking states figure of the present utility model.

Certainly, also can be the same with prior art, according to the suction of magnet, scold arrange the arbitrarily polarity Rankine-Hugoniot relations of the permanent magnet in depth blind hole and permanent magnetism pellet shot from a slingshot and the key of principle, promptly the shallow blind hole branch that constitutes marble bin can be located on lock body and the lock core, dark blind hole is then also corresponding with it and divide and be located on lock body and the lock core, the polarity of the permanent magnetism pellet shot from a slingshot in the polarity of permanent magnet on the key and each storehouse is corresponding one by one respectively, can play lock equally, open function.Form of structure between lock body, lock core and the key also can adopt the form of structure as Fig. 4, Fig. 5.

Embodiment 2:

Shown in Fig. 6,7, what present embodiment provided is that a kind of lock core 21 can be the magnetic control lock that axially relatively moves with respect to lock body 22.23 is lock tube among the figure, and 24 for being located at the back-moving spring between lock tube and the lock core.For pasting on the reliable top that guarantees key 3 and lock core 21 walls, so that the action of control permanent magnetism pellet shot from a slingshot can be provided with a flexure strip 25 on the bottom surface of its lock tube.Fig. 7 provides is the locking states of extracting out behind the key 3.
