Abstract

A lock with combined cylinder is composed of main body, lock core, round-end cylinders installed in lock core, flat-end cylinders installed in main body, and the springs and pins for said flat-end cylinders. Its features that said round-end and flat-end cylinders are respectively composed of extrnal hollow one and internal one, and for the flat-end cylinder, its external hollow one contains an internal one and a spring. Its advantage is the self locking function and mutual locking function of cylinders.

Description

Compound cylinder lock set

Technical field

The present invention relates to cylinder lock, the pellet shot from a slingshot that particularly relates to cylinder lock improves, and mainly is applicable to all kinds of door locks.

Background technology

The use of lock is extremely extensive, and people almost will come into contacts with lock every day, for example into and out of the door lock of door, ride, sail bicycle lock, automotive lock, the lock for motorcycle of vehicle, the drawer-lock in the office, bin lock or the like.Application difference according to lock, the large and small difference of lock is very big, mechanical strength and firm performance are also different, but for mechanical anti-theft lock, except fastness, what determine theftproof performance mainly is anti-technical unlocking function, more common theftproof lock because billiards structure is simple, adopts the special opening instrument to open at an easy rate at present, having a strong impact on the safe antitheft performance of lockset, is that current safety is taken precautions against department's problem anxious to be solved.

Summary of the invention

The present invention is in order to overcome the problem of the anti-technical unlocking function difference of prior art, and provide a kind of combined type pellet shot from a slingshot to make the design of lockset, its technical scheme is: a lock body is arranged, lock core is installed in the lock body, the round end pellet shot from a slingshot is installed in lock core, the tack pellet shot from a slingshot is installed in lock body, the tack pellet shot from a slingshot has spring and the offset that matches, lock core jack and round end pellet shot from a slingshot match with key, it is characterized in that a described round end pellet shot from a slingshot peace pellet shot from a slingshot is: round end pellet shot from a slingshot in installing in the hollow outer round end pellet shot from a slingshot, tack pellet shot from a slingshot and interior flat nose sub-spring in installing in the hollow outer tack pellet shot from a slingshot, round end pellet shot from a slingshot mating groove and interior round end pellet shot from a slingshot mating groove outside in the pellet shot from a slingshot cooperation recess of key, being shaped on.Set up interior pellet shot from a slingshot in the pellet shot from a slingshot with existing cylinder lock, be pellet shot from a slingshot and hollow outer pellet shot from a slingshot in pellet shot from a slingshot is, and interior pellet shot from a slingshot and hollow outer pellet shot from a slingshot length are all variant, even pellet shot from a slingshot is by technical unlocking outside hollow, pellet shot from a slingshot still can keep lock-out state, make lockset that self-locking and interlock function be arranged, be difficult to technical unlocking.

The specific embodiment

The invention discloses a kind of cylinder lock, with common structural similarity lock body 3 arranged, lock core is installed in the lock body 3, and lock core can be outer lock core 2 and internal cylinder 6, in, coupling mechanism such as movable block 4 and gear 5 etc. are arranged between the outer lock core, the round end pellet shot from a slingshot is installed in lock core, the tack pellet shot from a slingshot is installed in lock body, the tack pellet shot from a slingshot has spring 12 and the offset 11 that matches, lock core jack and round end pellet shot from a slingshot match with key, the innovation part of this programme is that pellet shot from a slingshot is improved design, promptly makes hollow outer round end pellet shot from a slingshot 13 and interior round end pellet shot from a slingshot 8, hollow outer tack pellet shot from a slingshot 15 and interior tack pellet shot from a slingshot 7, interior round end pellet shot from a slingshot 8 is installed in the hollow outer round end pellet shot from a slingshot 13, interior tack pellet shot from a slingshot 7 is installed in the hollow outer tack pellet shot from a slingshot 15, becomes the combined type pellet shot from a slingshot, flat nose sub-spring 10 in installing simultaneously.And the pellet shot from a slingshot of key 1 cooperate be shaped in the recess hollow outside round end pellet shot from a slingshot mating groove 16 and interior round end pellet shot from a slingshot mating groove 17.The mating groove of key 1 recess is not only corresponding with outer round end pellet shot from a slingshot when therefore unblanking, and also must match with interior round end pellet shot from a slingshot simultaneously.And the rotation of lock core must make outer tack pellet shot from a slingshot and interior tack pellet shot from a slingshot align with lock body and lock core fitting face simultaneously again.To prevent dialling pellet shot from a slingshot equally and also make anti-pellet shot from a slingshot 14 and the anti-group outer tack pellet shot from a slingshot 9 of I type dialled of hollow outer round end.

Claims

1, compound cylinder lock set, a lock body is arranged, lock core is installed in the lock body, the round end pellet shot from a slingshot is installed in lock core, the tack pellet shot from a slingshot is installed in lock body, the tack pellet shot from a slingshot has spring and the offset that matches, lock core jack and round end pellet shot from a slingshot match with key, it is characterized in that a described round end pellet shot from a slingshot peace pellet shot from a slingshot is: round end pellet shot from a slingshot (8) in installing in the hollow outer round end pellet shot from a slingshot (13), tack pellet shot from a slingshot (7) and interior flat nose sub-spring (10) in installing in the hollow outer tack pellet shot from a slingshot (15), in the pellet shot from a slingshot cooperation recess of key, be shaped on hollow outside round end pellet shot from a slingshot mating groove (16) and interior round end pellet shot from a slingshot mating groove (17).
