Abstract

A shrapnel type idle running lock core comprises a lock body, an inner lock core, a lock core block, an L-shaped side column, a starting core, shrapnels, a spring, a clutch assembly, an unlocking member, a key, and other accessories, wherein the lock core can realize idle running and starting by separating and connecting the L-shaped side column and the inner lock core and the starting core. The key and the inner lock core are eccentrically arranged, two opposite shrapnels are mounted into each shrapnel groove at the same time, the shrapnel in the inner lock core are aligned with a U-shaped groove by using the elastic force of the spring and two different movement directons, thus greatly increasing the key quantity, and effectively reducing the mutual opening rate of lock cores, and effectively preventing the lock core from being opened by the violence. The technology can be used in various lock sets.

Description

A kind of spring-piece type idle-run lock pin

Affiliated technical field

The utility model relates to a kind of spring-piece type idle-run lock pin.

Background technology

Common lock core locks internal cylinder by pellet shot from a slingshot and rotates.Common lock core is formed by combining by lock body, internal cylinder, pellet shot from a slingshot, spring.Under the lock core lock-out state, the spring performance elastic force effect in the lock marble hole ejects the pellet shot from a slingshot in the lock marble hole to internal cylinder, make in the lock marble hole pellet shot from a slingshot some by jacking in the inner lock core pellet shot from a slingshot hole; Simultaneously the pellet shot from a slingshot in the inner lock core pellet shot from a slingshot hole is backed down the origin-location, at this moment the pellet shot from a slingshot of lock body blocks internal cylinder, promptly is lock-out state.The shortcoming that this structure exists is: after the special instrument that adopts sufficient intensity and excellent toughness inserts lock core, twist lock core by force, the pellet shot from a slingshot that blocks lock core is twisted off, thereby make lock core lose its antitheft function.

Summary of the invention

In order to overcome the deficiency that the anti-riot power of common lock core is opened.The utility model provides a kind of spring-piece type idle-run lock pin.

The technical scheme that its technical problem that solves the utility model adopts is: the spring-piece type idle-run lock pin is made of lock body, internal cylinder, lock core fixture block, L shaped side column, startup core, shell fragment, spring, clutch component, the annexes such as part and key that undo the lock.In implementation process, for making internal cylinder and starting separating and connecting of core, need on internal cylinder, lock body and startup core, all to open a side column groove, L shaped side column has been gathered the function of side column and idle running cover, its short one be installed in the side column groove that starts core, in the long side column groove that is installed in lock body.At ordinary times when the key of not opening or be not complementary inserts internal cylinder, because the U-lag on the shell fragment is opened on different positions, shell fragment is under the active force of shell fragment spring, U-lag on the shell fragment forms dislocation, make the lock core fixture block be stuck in outside the U-lag, so side column fails to enter in the side column groove of internal cylinder, at this moment internal cylinder is in released state with the startup core, so during the twisting key, have only internal cylinder to rotate, and can not open lock core; When the key that is complementary inserts internal cylinder, U-lag aligning on the internal cylinder shell fragment, this moment is in the sagging U-lag to shell fragment of lock core fixture block under the effect of spring force, L shaped side column breaks away from the side column groove of lock body, enter in the side column groove of internal cylinder, make to start core and internal cylinder interlock, thereby correctly open lock core.Key and internal cylinder are eccentric to be provided with; The two relative shell fragments of in each shell fragment groove, packing into simultaneously, spring places in the middle of two shell fragments; Utilize the elastic force of spring, make shell fragment in the internal cylinder by align U-lag on the shell fragment of two different directions of motion; Also make the secret key amount of lock core increase greatly, thereby effectively reduce the mutual opening rate of lock core and effectively prevent violence unlatching lock core.

The spring-piece type idle-run lock pin has the following advantages:

One, can effectively reduce technical unlocking lock core;

Two, effectively reduce the mutual opening rate of lock core;

Three, effectively prevent violence unlatching lock core;

The specific embodiment

Use in the utility model implementation process be as shown in Figure 7 key and shell fragment as shown in Figure 8.

As shown in Figure 1 and Figure 2, the spring-piece type idle-run lock pin utilizes L shaped side column 5 to make internal cylinder 1 and starts and realizes dallying and unblank separating with connecting of core 9, so need all have a side column groove on internal cylinder 1, lock body 6 and startup core 9.Packing at an end of lock body 6 earlier during installation starts core 9 and L shaped side column 5, and the minor face of L shaped side column 5 is in the side column groove that starts core 9, and long limit is in the side column groove of lock body 6.In each shell fragment groove of internal cylinder 1, pack into two and be fixed on 6 li of lock bodies behind shell fragment 3, shell fragment spring 2 and the lock core fixture block 4 that has U-lag.At ordinary times when the key of not opening or be not complementary inserts internal cylinder 1, because of the U-lag on the shell fragment 3 is opened on different positions, shell fragment 3 is under the active force of shell fragment spring 2 and form U-lag mutual dislocation on the shell fragment 3, at this moment lock core fixture block 4 is in outside the U-lag of shell fragment 3, and the outer end of lock core fixture block 4 is just mutually concordant with the parting surface of lock body 6 with internal cylinder 1, the gap that does not have L shaped side column 5 in the internal cylinder, therefore L shaped side column 5 fails to enter in the side column groove of internal cylinder 1, the internal cylinder 1 of this moment is in released state with startup core 9, so during the key that twisting is not complementary, have only internal cylinder 1 to rotate, and can not open lock core.

As shown in Fig. 3, Fig. 4, when the key 12 that is complementary inserts internal cylinder 1,, the teeth groove depth on the key 12 is in the tram because changing promotion shell fragment 3, make the U-lag aligning on the shell fragment 3; Pellet shot from a slingshot 7 is under the active force of marble spring 8, lock core fixture block 4 is trapped in the U-lag of shell fragment 3, the side column groove that L shaped side column 5 breaks away from lock body 6 enters in the side column groove of internal cylinder 1, and the outer end of L shaped side column 5 is just mutually concordant with the parting surface of lock body 6 with internal cylinder 1, at this moment internal cylinder 1 and startup core 9 are in coupled situation, so during twisting key 12, internal cylinder 1 is by L shaped side column 5 and 9 interlocks of startup core, start core 9 and rotate together in company with key 12, thereby E really opens lock core by clutch component 10 part 11 that undoes the lock.

Shown in Fig. 5, Fig. 6 the application of spring-piece type idle-run lock pin in common lockset.Embodiment is identical with the above, therefore no longer statement.

Claims (1)

1. spring-piece type idle-run lock pin, it is characterized in that: the U-lag by key alignment shell fragment is opened lock core, two relative shell fragments are housed in each shell fragment groove, spring places in the middle of two shell fragments, lock core need the branch internal cylinder combine for two sections with the startup core at least, separate and connect the transmission of internal cylinder and startup core by L shaped side column, a suitable L shaped side column to be installed in the internal cylinder separate and connect internal cylinder and start transmission between the core and the lock core fixture block that is complementary with the U-lag on the shell fragment, simultaneously in internal cylinder, all have a side column groove of being convenient to L shaped side column activity on lock body and the startup core.
