Abstract

A rotary multiple spring theft-proof lock comprises a rotary key, a fixed lock core, a movable lock core, a plurality of lock springs, a fixed clasp and a lock pin. The key comprises a key column and a rotary key unlocking gear. The lock spring comprises a lock spring end, a lower marble of the lock spring, an upper marble of the lock spring, and a lock spring. A plurality of lock springs are reelingly arranged on the fixed lock cores and the movable lock cores. The upper marble of the lock spring is arranged in the rotary groove of the fixed lock core, and the lower marble is arranged in the rotary groove of the movable lock core. The lock spring end is arranged on the outer circle of the fixed lock core. A plurality of lock springs corresponding to the rotary key are reelingly arranged. The lock is good in theft-proof function. The thives or the professional people are not capable of placing freely the so-called ''master key'' and tools into the lock core. The lock changes the defects of the traditional lock, thereby achieving the safely theft-proof goal.

Description

Rotary many snaps theftproof lock

Affiliated technical field:

The utility model relates to a kind of rotary many snaps theftproof lock, belongs to lock.

Background technology:

At present, its key body of known conventional lock is that prolate is square, and cross or circular band magnetic etc. are multiple, though body is multiple, but the unlatching tooth is many on same cross section, on snap also is distributed in and parallels to the axis, though appellation theftproof locks all, but senior robber or professional unlocking person, can utilize so-called MASTERKRY and tool spindle in stretching into lock, under the situation of not destroying lockset, implement to unblank, therefore, the theftproof performance of known conventional lock is poor, brings the economic asset loss to people often.

Can not safe antitheft in order to overcome known conventional lock, avoid senior robber to utilize MASTERKRY under the situation of not destroying lockset, to implement to unblank, improve the antitheft effect of lockset, the utility model provides a kind of rotary many snaps theftproof lock, this theftproof lock can prevent that so-called MASTERKRY from directly stretching into and unblank, improve theftproof performance greatly.

Summary of the invention:

A kind of rotary many snaps theftproof lock of the utility model, comprise fixed lock core, flexible lock core, several snaps, rotary key, lock pin, fixing snap ring etc., it is characterized in that: the key operated tooth of 360 degree that on key cylinder, spiraling, which is provided with the corresponding unlatching tooth of snap on several and the lockset, remove to stir corresponding several snaps with the end face of this rotary key operated tooth and make the lockset unlatching; Be provided with several snaps with match corresponding rotary flexible lock core and fixed lock core of this key, this snap is by pellet shot from a slingshot under pellet shot from a slingshot, the snap on the snap, snap spring and snap plug are formed, this snap is provided with assembling along sideway swivel form in fixed lock core and the flexible lock core, pellet shot from a slingshot wall within it under this snap, in the following pellet shot from a slingshot pellet shot from a slingshot is housed, the snap spring is housed in the last pellet shot from a slingshot, the snap plug is housed on the outer of fixed lock core; One end of this lockset flexible lock core is provided with lockset and opens mouthful, and the other end is provided with the flexible lock core probe, and this flexible lock core probe is connected with lock pin, with packing ring and fixedly snap ring fix; After rotary key is opened mouthful insertion by lockset, rotate into, open all snap flexible lock core rotating band pendulum lock pin and rotate, reach the purpose of unlatching.

Wherein, the snap that described many snaps are mounted on fixed lock core (6) and the flexible lock core (5) is several, and it is arranged evenly to be rotation shape.

The beneficial effects of the utility model are: the key operated tooth that has changed known conventional lock is by axial distribution, defective between the tooth tooth on same cross section, the 360 key operated teeth of spending are spiraling on key cylinder, be rotation shape between the tooth tooth, prevention robber's MASTERKRY directly inserts, and has reached the purpose of real theftproof lock.
