The specific embodiment:

For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.

Shown in Fig. 1～2, the utility model comprises tapered end and key 1, described tapered end comprises lock skin 2, lock body 3, lock core 4, pintle hook lock 5, dead bolt 6 and lockhole 7, be provided with the pellet shot from a slingshot 9 of some groups of band springs 8 in lock body 3 and lock core 4 inside, in lock body 3 and lock core 4 inside along lockhole 7 radially parallel with some groups of pellets shot from a slingshot 9 be provided with a lock pin 10 movable up and down, be provided with an arc groove 11 in lock pin 10 bottoms with on the lock body 3 of the radially vertical direction of lockhole 7, the length of lock pin 10 is equal to or less than the distance of arc groove 11 bottoms to lockhole 7 greater than the degree of depth of arc groove 11; The position of corresponding lock pin 10 is provided with a shrinkage pool 12 on the lock core 4 that passes lockhole 7 opposites above the lock pin 10, and shrinkage pool 12 bottoms are to the length of lock core 4 outer peripheral distances greater than lock pin 10; Corresponding lock pin 10 is provided with a through hole 13 with the position of shrinkage pool 12 on key 1, and through hole 13 and lock pin 10 on shrinkage pool 12, the key 1 are in a straight line; Described lock pin 10 is the magnetic lock pin, and lock body 3 is the irony lock body, and lock core 4 is copper lock core.

When unblanking, use the private key 1 of band through hole 13 to insert lockhole 7, rotation, lock core 4 drive lock pins 10 and then rotate and slide along arc groove 11, ejected by arc groove 11, the through hole 13 that the lock pin 10 that rises passes on the key 1 in the lockhole 7 enters in the shrinkage pool 12, and after lock pin 10 was deviate from from arc groove 11 fully, lock just had been opened; When transfering to key 1, revolution lock core 4, because lock pin 10 is the magnetic lock pin, lock body 3 is the irony lock body, under suction, lock pin 10 bounces back from shrinkage pool 12, and withdraws from from the through hole 13 of key 1 and reset, and transfers to key to get final product then.

Shown in Fig. 3～4, be another kind of embodiment of the present utility model, the difference of itself and above-mentioned embodiment is, when lock pin 10 is made for nonmagnetic substance, as copper, irony etc., lock pin 10 upper outside in lock core 4 inside are provided with back-moving spring 14, the upper end of back-moving spring 14 and lock core 4 near, the lower end of back-moving spring 14 and lock pin 10 near.

When the present embodiment lockset was unblanked, its process and aforesaid way were basic identical, and its difference is, when lock pin 10 rises under the effect of arc groove 11, and pressed home spring 14 simultaneously, after lock pin 10 was deviate from from arc groove 11 fully, lock was opened; When transfering to key, revolution lock core 4, lock pin 10 bounces back under the effect of back-moving spring 14, withdraws from from shrinkage pool 12, and withdraws from from the through hole 13 of key 1 and reset, and at this moment, transfers to key to get final product.

The above-mentioned specific embodiment can not be as the restriction to the utility model protection domain, and for those skilled in the art, any alternate modification or conversion that the utility model embodiment is made all drop in the protection domain of the present utility model.

The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
