The utility model utilizes the principle that the permanent magnetism pellet shot from a slingshot same sex is repelled each other, there is a natural attraction between the sexes, reaches the purpose of locking or unlocking.If fixedly installing mechanical billiard and spring structure additional in the lock body, then Suo key rate can also improve.The utility model safety performance is good, low cost of manufacture, and assembling is simple, and is easy to use, can be widely used in the daily lifes such as room, automobile, motorcycle, bicycle, strongbox, all kinds of door and windows.

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is the vertical profile schematic diagram of a kind of permanent magnetism clutch safety lock structure of expression.

Fig. 2 is the rear elevation of safety lock shown in Figure 1.

Fig. 3 is the structural representation that safety lock shown in Figure 1 installs mechanical billiard and spring additional.

Referring to Fig. 1 and Fig. 2, a kind of permanent magnetism clutch safety lock comprises fixedly lock body 1, passive lock body 2, permanent magnetism pellet shot from a slingshot 6,7 and key body 3, and passive lock body 2 is loaded on the center of cylindrical fixedly lock body 1 rotationally.

Fixedly lock body 1 connects with passive lock body 2 by the jump ring 9 of its bottom surface.Fixedly the bottom surface of lock body 1 also is provided with the screw hole 4 that fixing lock body 1 can be fixed on the fixture.Fixedly be arranged with six trajectories that longitudinally run through 13 in the lock body 1, these trajectories 13 can be selected arbitrarily to arrange, to improve the key rate of lock.One group two the identical permanent magnetism pellets shot from a slingshot 6 of isolated, relative two end polarity are housed in each trajectory 13, and very anodal as the right side of left side permanent magnetism pellet shot from a slingshot in a certain trajectory, then the left utmost point of right side permanent magnetism pellet shot from a slingshot also is anodal; Vice versa.The left end of each trajectory 13 promptly at the plumbous material 5 of the bottom surface of fixing lock body 1 encapsulation, skids off to stop permanent magnetism pellet shot from a slingshot 6.

In passive lock body 2, be arranged with same fixedly six relative one by one holes 16 of all trajectories 13 of lock body 1.Because permanent magnetism pellet shot from a slingshot 6 same sexes are repelled each other, the right side permanent magnetism pellet shot from a slingshot 6 in the trajectory 13 is pushed in the hole 16 of corresponding passive lock body 2 under magneticaction, realizes locking thus.

Key body 3 is disc, be equipped with in it with the permanent magnetism pellet shot from a slingshot in fixing lock body 1 trajectory 13 6 indirect relative, the identical permanent magnetism pellet shot from a slingshot 7 of relative two end polarity.For example, are negative poles as the left utmost point of this permanent magnetism pellet shot from a slingshot 7, this also is a negative pole with polarity of permanent magnetism pellet shot from a slingshot 6 indirect relative in fixing lock body 1 trajectory 13 extremely so; Vice versa.
