Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

Fig. 1 is an organigram of the present utility model;

Comprise lock body (1), lock core (2), a plurality of pellets shot from a slingshot hole (3) in the structural form shown in Figure 1, the material of their structure and employing is identical with existing ball lock head.Key (7) the then key with existing Magnetic lock is identical, for nonmagnetic substance is made.It is characterized in that: have an A structure in the cylinder lock at least, also have a B structure or a C-structure in addition at least.

The A structure is one group of structure on the right among Fig. 1, and it is that ferromagnetic pellet shot from a slingshot (4), a ferromagnetic pellet shot from a slingshot of abnormity (10) and a permanent magnetism pellet shot from a slingshot (5) of making of ferromagnetic material is housed in a pellet shot from a slingshot hole (3).The ferromagnetic pellet shot from a slingshot of abnormity (10) can be made into special-shaped marble (cylindrical billiard that has reduced as taper, end diameter) with ferromagnetic material, also can adopt non-ferromagnetic material to be made into common cylinder pellet shot from a slingshot shape and replace, as long as the absorption affinity that produces between special-shaped ferromagnetic pellet shot from a slingshot (10) and ferromagnetic pellet shot from a slingshot (4) is less than the absorption affinity of generation between the ferromagnetic pellet shot from a slingshot of key (7) position and permanent magnetism pellet shot from a slingshot (5); Wherein ferromagnetic pellet shot from a slingshot (4) is fixed on the top of pellet shot from a slingshot hole (3), and the ferromagnetic pellet shot from a slingshot of mobilizable abnormity (4), permanent magnetism pellet shot from a slingshot (5) place pellet shot from a slingshot hole (3) successively, and its bonding surface just in time is in when locking states on the bonding surface of lock body (1) and lock core (2); In this group pellet shot from a slingshot, ferromagnetic pellet shot from a slingshot of mobilizable at ordinary times abnormity (10) and permanent magnetism pellet shot from a slingshot (5) are attached together with the ferromagnetic pellet shot from a slingshot (4) that is fixed on the top in pellet shot from a slingshot hole (3); The bonding surface of permanent magnetism pellet shot from a slingshot (5) and ferromagnetic pellet shot from a slingshot (10) just in time is positioned on the bonding surface of lock body (1) and lock core (2), so the pellet shot from a slingshot in this pellet shot from a slingshot hole (3) does not have blocking function at ordinary times, but when attempting to adopt fully the key operated tapered end made from ferromagnetic material or adopting ferromagnetic pellet shot from a slingshot to survey, because this pellet shot from a slingshot hole (3) is not a through hole, permanent magnetism pellet shot from a slingshot (5) and ferromagnetic pellet shot from a slingshot (8) can wholely move, and produce locking.Therefore this group structure has the anti-function of joining of key.

The B structure is one group of structure on the left side among Fig. 1, it is that ferromagnetic pellet shot from a slingshot (9), the permanent magnetism pellet shot from a slingshot (5) that a nonmagnetic substance pellet shot from a slingshot (8), a granulated iron magnetic material are made is housed respectively in a pair of pellet shot from a slingshot hole (3), nonmagnetic substance pellet shot from a slingshot (8) is fixed on the top of pellet shot from a slingshot hole (3), a mobilizable ferromagnetic pellet shot from a slingshot (9) and a permanent magnetism pellet shot from a slingshot (5) place pellet shot from a slingshot hole (3) successively, go up being embedded with a ferromagnetic pellet shot from a slingshot (6) of making of ferromagnetic material on the position to pellet shot from a slingshot hole (3) at key (7).In this group pellet shot from a slingshot, mobilizable permanent magnetism pellet shot from a slingshot (5) and ferromagnetic pellet shot from a slingshot (9) are attached together in each pellet shot from a slingshot hole (3), under the repulsion effect of the permanent magnetism pellet shot from a slingshot (5) in the pellet shot from a slingshot hole (3) of correspondence, are attached on the nonmagnetic substance pellet shot from a slingshot (8).Because the position of permanent magnetism pellet shot from a slingshot (5) just in time between lock body (1) and lock core (2), is therefore blocked lock core (2) and is made it and can not rotate.After inserting key (7), because ferromagnetic pellet shot from a slingshot (6) is magnetized, and come the repulsion of the permanent magnetism pellet shot from a slingshot (5) in the self-corresponding pellet shot from a slingshot hole (3) to disappear, permanent magnetism pellet shot from a slingshot (5) drives ferromagnetic pellet shot from a slingshot (9) and is adsorbed on the ferromagnetic pellet shot from a slingshot (6), because pellet shot from a slingshot is differential, the bonding surface of permanent magnetism pellet shot from a slingshot (5) and ferromagnetic pellet shot from a slingshot (9) just in time is positioned on the bonding surface of lock body (1) and lock core (2), and the blocking function of this group structure is disengaged.Therefore do not have spring in this group structure, adopt to apply behind the torsion when handling this group pellet shot from a slingshot, can't remove the blocking function of this group structure with means such as master keys.After this group structure was subjected to the demagnetization processing, the position of ferromagnetic pellet shot from a slingshot (9) just in time between lock body (1) and lock core (2), was blocked lock core (2) and is made it and can not rotate, but therefore should the also anti-back magnetic treatment of group structure.

C-structure is one group of structure in the middle of Fig. 1, it is that a granulated iron magnetic marble (4), a ferromagnetic pellet shot from a slingshot of abnormity (10), a permanent magnetism pellet shot from a slingshot (5) are housed in a pellet shot from a slingshot hole (3), wherein ferromagnetic pellet shot from a slingshot (4) is fixed on the top of pellet shot from a slingshot hole (3), the ferromagnetic pellet shot from a slingshot of mobilizable abnormity (4), permanent magnetism pellet shot from a slingshot (5) place pellet shot from a slingshot hole (3) successively, its bonding surface when locking states and the bonding surface of lock body (1) and lock core (2) stagger, go up being embedded with a ferromagnetic pellet shot from a slingshot (6) of making of ferromagnetic material on the position in pellet shot from a slingshot hole (3) at key (7).The ferromagnetic pellet shot from a slingshot of abnormity (10) can be made into special-shaped marble (cylindrical billiard that has reduced as taper, end diameter) with ferromagnetic material, also can adopt non-ferromagnetic material to be made into common cylinder pellet shot from a slingshot shape and replace, as long as the absorption affinity that produces between special-shaped ferromagnetic pellet shot from a slingshot (10) and ferromagnetic pellet shot from a slingshot (4) is less than the absorption affinity that produces between ferromagnetic pellet shot from a slingshot (6) and permanent magnetism pellet shot from a slingshot (5).In this group pellet shot from a slingshot, mobilizable permanent magnetism pellet shot from a slingshot (5) and ferromagnetic pellet shot from a slingshot (9) are attracted on the ferromagnetic pellet shot from a slingshot (4) in pellet shot from a slingshot hole (3) at ordinary times, because the position of permanent magnetism pellet shot from a slingshot (5) just in time between lock body (1) and lock core (2), is therefore blocked lock core (2) and is made it and can not rotate.After inserting key (7), because ferromagnetic pellet shot from a slingshot (6) is magnetized, the suction that produces between ferromagnetic pellet shot from a slingshot (6) and permanent magnetism pellet shot from a slingshot (5) is greater than the suction between ferromagnetic pellet shot from a slingshot of abnormity (10) and ferromagnetic pellet shot from a slingshot (4), permanent magnetism pellet shot from a slingshot (5) drives special-shaped ferromagnetic pellet shot from a slingshot (10) and is adsorbed on the ferromagnetic pellet shot from a slingshot (6), because pellet shot from a slingshot is differential, the bonding surface of permanent magnetism pellet shot from a slingshot (5) and special-shaped ferromagnetic pellet shot from a slingshot (10) just in time is positioned on the bonding surface of lock body (1) and lock core (2), and the blocking function of this group structure is disengaged.Therefore do not have spring in this group structure, adopt to apply behind the torsion when handling this group pellet shot from a slingshot, can't remove the blocking function of this group structure with means such as master keys.After this group structure was subjected to the demagnetization processing, the position of ferromagnetic pellet shot from a slingshot (10) just in time between lock body (1) and lock core (2), was blocked lock core (2) and is made it and can not rotate, and therefore this group structure also can be prevented the demagnetization unlatching.

Basic comprising of the present utility model is an A structure, and a B structure or C-structure and A textural association are arranged in addition again.Certainly the also combination of an A structure, a B structure and a C-structure, or A, A, B combination, A, B, B combination, A, B, C, C combination etc.
