The specific embodiment
With reference to Fig. 1 ~ Fig. 5, this lock, comprises key, lock core 12 and lock housing 20, the front portion of described lock housing 20 is provided with the first marble hole 18 and the second marble hole 19, the front portion of described lock core 12 is provided with three marble hole 11 and four marble hole 10 corresponding with the first marble hole 18 in described lock housing 20 and the second marble hole 19, the rear portion of described lock housing 20 is provided with the 5th marble hole 21, the rear portion of described lock core 12 is provided with six marble hole 13 corresponding with the 5th marble hole 21, one end of the close key insertion hole that the front portion of lock housing 20 described here refers to, be the rear portion of lock housing 20 away from one end of key insertion hole, described the first marble hole 18, the second marble hole 19, the 3rd marble hole 11, the 4th marble hole 10, in the 5th marble hole 21 and the 6th marble hole 13, be provided with corresponding pellet 26, 25, 22, 23, 27, 24, and be furnished with little spring in each marble hole of lock housing 20, described key mates with lock core 12, and it is all tapered that it is assemblied in pellet in lock core, and lock housing 20 is arranged in lock tube 6, these are all known technologies, repeat no more.Described key comprises the shank of the key 1, connecting portion 2 and key bit 4, described key bit 4 is arranged on described connecting portion 2, described connecting portion 2 is connected with the shank of the key 1 is into a single integrated structure, position, the hole surrounding that described connecting portion 2 is installed key bit 4 is evenly distributed with five root posts 3, this five root post 3 is highly different, described key bit 4 is provided with slotted hole 28, in described lock core 12, be provided with the five piece slide cores 7 corresponding with described column 3, because the height of column 3 can design arbitrarily, and then slide core 7 length corresponding with it are also different, like this, manufacture successful lockset, its transformable quantity is just a lot, solve the problem of mutual opening rate, visible, because column 3 its transformable quantity of height are a lot, thereby, its mutual opening rate is extremely low, described slide core 7 is provided with the taper chute 8 coordinating with the pellet 23 in described the 4th marble hole 10, pellet 22 in described the 3rd marble hole 11 mates with the tartar 5 on described key bit 4, in described lock core 12, be provided with slide bar 14, described slide bar 14 is provided with multiple flanges 15 that external diameter does not wait, pellet 24 in described the 6th marble hole 13 is against on each flange outer circle wall, between adjacent flange 15, there is landslide 29, make it carry out transition, like this, pellet 24 can be light between flanges 15 at different levels, move, described slide bar 14 can extend in the slotted hole 28 of key bit 4, end at described slide core 7 and slide bar 14 is equipped with spring 9, 17.In the present invention, wherein on slide bar 14, there is deep hole 16, spring 17 parts of slide bar 14 ends are placed in deep hole 16, keep like this stability of these place's spring 17 elastic force.Second embodiment of the present invention is the structure that the taper chute 8 in slide core 7 is changed into projection 30, with reference to Fig. 7 ~ Fig. 9; The position of certain its projection 30 and slide core 7 bodies have the conical surface 31 and carry out transition, are convenient to pellet 24 and move in projection 29 from the body of slide core 7, and other structure is all identical.
Operating principle of the present invention is as follows: while unblanking, key is inserted to lock core 12, tartar 5 on key bit 4 mates with the pellet 22 in the 3rd marble hole 11 on lock core 12, simultaneously, after key inserts, the slide core 7 of the column 3 pushing lock cylinder 12 interior correspondences on connecting portion 2, after slide core 7 moves, pellet 23 on lock core 12 in the 4th marble hole 10 just slips in the taper chute 8 of slide core 7, or just move to the top of slide core 7 projections 29, after key pushes, slide bar 14 is by the slotted hole 28 extending on key bit 4, when key is shifted onto behind position, to cause slide bar 14 to move, pellet 24 in the 6th marble hole 13 is dropped on the flange 15 that corresponding external diameter do not wait, now, the 3rd marble hole 11 on lock core 12, the 4th marble hole 10 is just concordant with the outer circumference surface of lock core 12 with the pellet on the 6th marble hole 13, simultaneously, the first marble hole 18 in lock housing 20, the second marble hole 19 is also just concordant with the inner peripheral surface of lock housing 20 with the pellet in the 5th marble hole 21, thereby, rotate key, just rotatable lock core 12, reach the object of unblanking.
When pull-out key, key bit 4 is along with pull-out, the pellet 22 of the 3rd marble hole 11 moves on the tartar 5 on key bit 4, and pellet 22 parts in the 3rd marble hole 11 are entered in the first marble hole 18, and promoting slide core 7, moves by the spring 9 of slide core 7 ends, make the pellet 23 in the 4th marble hole 10 from taper chute 8, shift out or make the pellet 23 in the 4th marble hole 10 to move from the top of projection 29, in this step, after pellet 23 shifts out from taper chute 8, also part is entered into the second marble hole 19, when pellet 23 is from the top of projection 29 is slided, pellet 25 parts in the second marble hole 19 enter into the 4th marble hole 10, simultaneously, under the effect of slide bar 14 end springs 17, promote slide bar 14, the position of each flange 15 is changed, pellet 24 in the 6th marble hole 13 moves between each flange 15, and the pellet 24 in the 6th marble hole 13 is also partly entered in the 5th marble hole 21 of lock housing 20, or pellet 27 parts in the 5th marble hole 21 are entered in the 6th marble hole 13, by above-mentioned known, when after key pull-out, move the pellet position in each marble hole, and lock core 12 and lock housing 20 are combined, and blocks by lock core 12 and lock housing 20, so just reaches the object of locking.
In the present invention, after locking, slide bar 14 in lock core 12 can adopt foreign object to move it, once foreign object contact slide bar 14, slide bar 14 moves immediately, and after slide bar 14 moves, the flange 15 that external diameter does not wait moves accordingly, after flange 15 moves, make the pellet 24 corresponding changes in position in the 6th marble hole 13, only in the time that slide bar 14 arrives accurately position, just can make the pellet 24 in the 6th marble hole 13 concordant with the outer circumference surface of lock core 12, and adopt foreign object when slide bar 14 is moved, due to the residing position of unknown flange 15, to be difficult to grasp accurate dynamics identical while insertion with key, so be difficult to this place's pellet in unlocking condition, thereby, it is very difficult adopting technical unlocking.
