Abstract

The utility model relates to a cylinder lock hidden with a self-destroy marble, which comprises a lock body 1, a lock core 2, a keyhole 3, a core marble 5, a marble 6 and a spring 7, wherein the core marble 5, the marble 6 and the spring 7 are arranged in a marble hole 4. The utility model is characterized in that the lock core 2 is provided with at least one or more than one hidden marble hole 8 which is connected with the marble hole 4 of the lock core 2 through a coupled rod groove 10 internally provided with a coupled rod 9; the lock body 1 is provided with the marble hole 4 which corresponds to the hidden marble hole 8. When the lock is unlocked with a self key, a hidden marble group doesn't take effect, and the lock can be unlocked normally; when foreign matters are used by a thief for unlocking the lock, the hidden marble group can automatically destroy the lock which can no longer be unlocked with any methods; so the lock has high theft prevention performance. The utility model which is formed by additionally installing the hidden marble hole 8, the coupled rod 9 and the coupled rod groove 10 on the lock core 2 of a common cylinder lock is a cylinder lock which has the advantages of limited manufacturing cost increase and heightened theft prevention performance.

Five, the specific embodiment

The cylinder lock of hiding the self-destruction pellet shot from a slingshot described in the utility model, basic structure is: comprise that rotating lock core 2 is arranged in the lock body 1, keyhole 3 is arranged in the lock core 2.One several pellet shot from a slingshot holes 4 that communicate with keyhole 3 of row are arranged in lock body 1 and the lock core 2, a core pellet shot from a slingshot 5, pellet shot from a slingshot 6, spring 7 are arranged in each pellet shot from a slingshot hole 4, also have sealing of hole 8 sealing of holes.A dark pellet shot from a slingshot hole 8 is arranged on the lock core 2, crank-guide way 10 by built-in trace 9 links to each other with a lock core marble hole 4, core pellet shot from a slingshot 5 in this lock core marble hole 4 is cylinder pin that round end, an afterbody have skewed slot, there is a pellet shot from a slingshot hole 4 corresponding on the lock body 1, shown in Fig. 1-11 with dark pellet shot from a slingshot hole 8.Core pellet shot from a slingshot 5, pellet shot from a slingshot 6 are meant that not only cylinder pin also comprises the pellet shot from a slingshot of different shape.With four examples the different structure of hiding self-destruction pellet shot from a slingshot group is done concrete the introduction respectively below in conjunction with accompanying drawing 1-11.

Embodiment one, the described cylinder lock of hiding the self-destruction pellet shot from a slingshot of present embodiment is to adopt above-mentioned basic structure, its concrete structure of hiding self-destruction pellet shot from a slingshot group is: select a preposition pellet shot from a slingshot hole 4 corresponding with dark pellet shot from a slingshot hole 8 in several pellet shot from a slingshot holes 4 of row on lock body 1, built-in pellet shot from a slingshot 6 springs 7 double as except that having former effect is hidden pellet shot from a slingshot 6 and is used, shown in Fig. 1-6.

Embodiment two, the described cylinder lock of hiding the self-destruction pellet shot from a slingshot of present embodiment is to adopt above-mentioned basic structure, its concrete structure of hiding self-destruction pellet shot from a slingshot group is: have one and one to arrange the not pellet shot from a slingshot hole 4 on same straight line, several pellet shot from a slingshot holes 4 on the lock body 1, these hole 4 built-in pellets shot from a slingshot 6, spring 7, corresponding with dark pellet shot from a slingshot hole 8, shown in Fig. 2-7.

Embodiment three, the described cylinder lock of hiding the self-destruction pellet shot from a slingshot of present embodiment is to adopt above-mentioned basic structure, its concrete structure of hiding self-destruction pellet shot from a slingshot group is: dark pellet shot from a slingshot hole 8 built-in pellet shot from a slingshot 6, the springs 7 hidden on the lock core 2, several pellet shot from a slingshot holes 4 of row on lock body 1, wherein there is a preposition pellet shot from a slingshot hole 4 corresponding, shown in Fig. 4,5,6,8,9,10 with dark pellet shot from a slingshot hole 8.Annotate: the elastic force of dark pellet shot from a slingshot hole 8 inner springs 7 is greater than the elastic force of corresponding pellet shot from a slingshot hole 4 inner springs 7.

Embodiment four, the described cylinder lock of hiding the self-destruction pellet shot from a slingshot of present embodiment is to adopt above-mentioned basic structure, its concrete structure of hiding self-destruction pellet shot from a slingshot group is: dark pellet shot from a slingshot hole 8 built-in pellet shot from a slingshot 6, the springs 7 hidden on the lock core 2, at lock body 1 a pellet shot from a slingshot hole 4 corresponding with it and sealing of hole 11 are arranged, this pellet shot from a slingshot hole 4 and several pellet shot from a slingshot holes 4 of row are not on same straight line, shown in Fig. 4,5,6,9,10,11.

The cylinder lock of hiding the self-destruction pellet shot from a slingshot described in the utility model, be that dark pellet shot from a slingshot hole 8 is set on lock core 2, crank-guide way 10 by built-in trace 9 is connected with a preposition lock core marble hole 4, and core pellet shot from a slingshot 5 afterbodys in this lock core marble hole 4 have a skewed slot, and trace 9 inserts in the skewed slot.During this lock use self key unlocking, the key bit of key makes lock core 2 interior all core pellet shot from a slingshot 5 tail end faces overlap with unlatching face, lock core 2 is rotatable in lock body 1, when forwarding the corresponding 4 pairs of timings in pellet shot from a slingshot hole of lock core 2 dark pellet shot from a slingshot holes 8 and lock body 1 to, push down the skewed slot of head core pellet shot from a slingshot 5 afterbodys of core pellet shot from a slingshot 5 because of the key bit of key and push down arc trace 9 again, trace 9 has blocked 8 mouthfuls in dark pellet shot from a slingshot hole, and pellet shot from a slingshot 6 can't be worked, and lock core 2 can be rotated further and open.When opening with foreign matter, lock core 2 turns to the corresponding 4 pairs of timings in pellet shot from a slingshot hole of lock core 2 dark pellet shot from a slingshot holes 8 and lock body 1 in lock body 1; Pellet shot from a slingshot 6 is forcing trace 9 after the 5 direction displacements of core pellet shot from a slingshot and insert in the pellet shot from a slingshot hole 4 of dark pellet shot from a slingshot hole 8 or lock body 1 correspondence under the effect of spring 7, block unlatching face and can't pirate of the open.Because of this pellet shot from a slingshot 6 has been positioned at the position of departing from keyhole 3, can stir this pellet shot from a slingshot of hiding 6 without any method, non-destructive method can not be opened again, and high theftproof is arranged.
