Compared with the prior art, the utility model presents weak magnetic, permanent magnetism and ferromagnetic three kinds of different pellets shot from a slingshot owing to having adopted, and has changed the allocation position of the pellet shot from a slingshot in the part pellet shot from a slingshot hole.Make the utility model not only can prevent on-the-spot preparation unlatching but also can prevent the demagnetization unlatching, and practical good reliability.Have simple and practically, can prevent that various technical means from opening, safety is given birth to strong, and the characteristics that cost is low can be widely used in various with the lock occasions.

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

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

Lock body in the structural form shown in Figure 1 (1), lock core (2), a plurality of pellets shot from a slingshot hole (3), the material of their structure and employing is identical with existing ball lock head.Key (7) is then identical with existing magnetic bullet tapered end, is the cylinder of copper or aluminium.In a plurality of pellets shot from a slingshot hole (3), have at least a weak magnetic marble (4) and the permanent magnetism pellet shot from a slingshot (5) that permanent-magnet material is made are housed in the pellet shot from a slingshot hole (3), wherein weak magnetic marble (4) is fixed on the top of pellet shot from a slingshot hole (3), and permanent magnetism pellet shot from a slingshot (5) places pellet shot from a slingshot hole (3) not fix can be movable; Go up being embedded with the ferromagnetic pellet shot from a slingshot (6) of using the pure iron material on the position in pellet shot from a slingshot hole (3) at key (7); Weak magnetic marble (4) can adopt non-ferromagnetic material to be made into common cylinder pellet shot from a slingshot shape, also can become special-shaped marble (cylindrical billiard that has reduced as taper, end diameter), as long as the absorption affinity that produces between weak magnetic marble (4) and permanent magnetism pellet shot from a slingshot (5) is less than the absorption affinity of generation between ferromagnetic pellet shot from a slingshot (6) and permanent magnetism pellet shot from a slingshot (5) with the pure iron material; In this group pellet shot from a slingshot, mobilizable at ordinary times permanent magnetism pellet shot from a slingshot (5) is attracted on the fixing weak magnetic marble (4), and the position of permanent magnetism pellet shot from a slingshot (5) just in time between lock body (1) and lock core (2), is blocked lock core (2) and made it and can not rotate; After inserting key (7), permanent magnetism pellet shot from a slingshot (5) will withdraw from lock body (1) and be adsorbed on the ferromagnetic pellet shot from a slingshot (6), thereby remove the blocking function of this group pellet shot from a slingshot; Because the blocking function of this group pellet shot from a slingshot can not be disengaged after demagnetization is handled, therefore can prevent from the demagnetization of tapered end is opened.In addition, at least also have in the pellet shot from a slingshot hole (3) a weak magnetic marble (4), a permanent magnetism pellet shot from a slingshot (5) and a granulated iron magnetic marble (6) are housed, wherein weak magnetic marble (4) is fixed on the top of pellet shot from a slingshot hole (3), and permanent magnetism pellet shot from a slingshot (5) and ferromagnetic pellet shot from a slingshot (6) place pellet shot from a slingshot hole (3) successively; In this group pellet shot from a slingshot, mobilizable at ordinary times permanent magnetism pellet shot from a slingshot (5) and ferromagnetic pellet shot from a slingshot (5) are attached together with the weak magnetic marble of fixing (4), the bonding surface of permanent magnetism pellet shot from a slingshot (5) and ferromagnetic pellet shot from a slingshot (6) just in time is positioned on the bonding surface of lock body (1) and lock core (2), so this group pellet shot from a slingshot does not have blocking function at ordinary times; When adopting the mode of souning out by grain to prepare key, the result who obtains should have ferromagnetic pellet shot from a slingshot (6) on the correspondence position on the key (7), Pei Zhi key is when reality is opened in view of the above, this locational ferromagnetic pellet shot from a slingshot (6) can make this group pellet shot from a slingshot break away from the normal position, produce blocking function on the contrary, therefore can prevent from the scene preparation of tapered end is opened.

As the pellet shot from a slingshot in all pellet shot from a slingshot holes (3) is installed by the structure of above-mentioned two kinds of pellet shot from a slingshot groups is staggered, be packed with ferromagnetic pellet shot from a slingshot (6) with the pure iron material in the relevant position of key (7), then there is not the possibility of being opened by on-the-spot preparation in the utility model.The utility model not destroying under the outward appearance situation of original key, all is difficult to accomplish to duplicating of original key after adding a coating (as chromium plating) on the key (7).There is not the permanent magnetism pellet shot from a slingshot on the key because the utility model uses, so the situation that key is scrapped whole tapered end by demagnetization can not take place.
