Description

Tapered end with the coaxial lock core of tandem many groups

The utility model relates to a kind of tapered end, particularly a kind of tapered end with the coaxial lock core of tandem many groups.

Present many locks are for effectively antitheft, all adopt major and minor two cover lock cores, but major and minor lock core all adopts the coaxial package or the form of suit up and down, and main lock core is furnished with master key, the secondary key of auxiliary lock core.Chinese patent 96244669.6 discloses a chain of theftproof lock of a kind of primary and secondary, its lock core is made up of many groups of mutual a chain of locking or the lock core more than many groups, improved safety, but must use the key more than two or two to open simultaneously, the cost height, and lost wherein that a key all can cause opening lock, use inconvenient.

The purpose of this utility model provides a kind of tapered end of arranging the above coaxial lock core of two covers or two covers before and after having, only can open lock to specific key with one, effective pick-proof and anti-theft of while.

To achieve the above object, the technical solution of the utility model is as follows:

A kind of tapered end with the coaxial lock core of tandem many groups comprises lock body, lock core and plectrum 1; Lock core 2 and rear lock core 3 before lock core comprises; Preceding lock core 2 is coaxial with rear lock core 3; Pellets shot from a slingshot 4 before preceding lock core 2 is provided with some groups; Pellet shot from a slingshot 5 after rear lock core 3 was provided with some groups; Before lock core 2 and rear lock core 3 be provided with a lockhole that runs through 10, the axis of lock core 2 and rear lock core 3 before lockhole 10 departs from, and be prolate shape; Plectrum 1 is contained on the rear lock core 3.

Because adopt above-mentioned structure, preceding lock core 2 and rear lock core 3 must rotate simultaneously could open lock, make except that using specific key, can't open lock, anti-theft pick-proof.

Below in conjunction with drawings and Examples the utility model is described in further detail:

Fig. 1 is an assembling drawing of the present utility model;

Fig. 2 is a rear elevation of the present utility model;

Fig. 3 is the A-A sectional view of Fig. 2;

Fig. 4 is the B-B sectional view of Fig. 2.

A kind of tapered end with the coaxial lock core of tandem many groups comprises lock body, lock core and plectrum 1; Lock core 2 and rear lock core 3 before lock core comprises; Preceding lock core 2 is coaxial with rear lock core 3; Pellets shot from a slingshot 4 before preceding lock core 2 is provided with some groups; Pellet shot from a slingshot 5 after rear lock core 3 was provided with some groups; Before lock core 2 and rear lock core 3 be provided with a lockhole that runs through 10, before lockhole 10 departs from lock core 2 and back lock account for 3 axis, and are prolate shape; Plectrum 1 is contained on the rear lock core 3.

Lock body 6 and rear locking 7 before lock body comprises; Preceding lock body 6 is enclosed within on the preceding lock core 2; Rear locking 7 is enclosed within on the rear lock core 3; Preceding lock body 6 is connected by attachment screw 8 with rear locking 7, by alignment pin 9 location.

When lock quilt sled colluded, as if lock core 2 before preceding pellet shot from a slingshot 4 on the lock core 2 before only stirring and the rotation, because rear lock core 3 does not rotate, and plectrum 1 was contained on the rear lock core, locks and does not open; If only stir the back pellet shot from a slingshot 5 on the rear lock core 3,, rear lock core 3 can't rotate because being subjected to preceding the spacing of lock core 2.Thereby effectively reach the purpose that anti-theft pick-proof colludes.
