Abstract

The utility model discloses a lock cylinder on-off structure whose night lock cylinder is capable of idling, which comprises a lock body, a front lock core and a rear lock core which are arranged in the lock body, a locking side column and a slider are arranged in the front lock core, and a lock pin which is contact with the slider is arranged in the rear lock core. The utility model is characterized in that one of the slider and the locking side column is in contact with the other one through an inclined plane. Because one of the slider and the locking side column is in contact with the other one through an inclined plane, the contact friction between the two is capable of being reduced to lead parts to move more flexible, and the use effect of a lock is increased.

Description

The lock core clutch structure that cylinder of spring lock can dally

Technical field

The utility model belongs to mechanical lock, relates to a kind of lock core clutch structure of cylinder lock.

Background technology

At present, the lock core clutch structure (seeing Chinese patent application No. 200710034226.3) that has a kind of lock core that is used for cylinder lock and blade lock to dally.Relative rear lock core of lock core and lock body were done the idle running of 360 degree before tapered end adopted when can be implemented in locking after this lock core clutch structure, thereby reached effectively anti-skilled unlocking and sled twistlock core.But owing to all adopt the inclined-plane contact between slide block and the locking side column in this structure,, make the component motion not too flexible, influence the result of use of locking so friction is bigger.

The utility model content

The purpose of this utility model is at above-mentioned situation, the lock core clutch structure that provides a kind of cylinder of spring lock to dally.This architecture advances the way of contact between slide block and the locking side column, reduced friction, improved the result of use of lock.

The utility model purpose is achieved in that the lock core clutch structure that cylinder of spring lock can dally comprises lock body, interior preceding lock core and the rear lock core of lock body, be provided with locking side column and slide block in the preceding lock core, be provided with the lock pin that contacts with slide block in the rear lock core, between slide block and the locking side column, one of them adopts the inclined-plane to contact with another.

Described slide block can be a rectangular block, or spherical pieces.

When slide block adopts spherical pieces,, can also between lock pin and spherical pieces, increase drive block if lock core is long.

Lock core clutch structure of the present utility model can adapt to all cylinder lock and blade spring locks of adopting locking side column locking lock core.If the corresponding breach of opening with the lock pin chute can match lock pin with this breach on the lock body afterbody is used for the step of lock core stop bit, just constituted the tapered end that lock core can dally.

The utility model makes the component motion more flexible because between slide block and locking side column, one of them adopts the inclined-plane to contact with another, can reduce contact friction between the two, improves the result of use of lock.

Further specify technical solutions of the utility model below in conjunction with accompanying drawing.

The specific embodiment

See Fig. 1, the lock core clutch structure that cylinder of spring lock can dally, lock core 6 and rear lock core 12 before comprising, be provided with locking side column 3 in the preceding lock core 6, be pressed with spring 5 on the locking side column 3, the slide block chute 13 that communicates with the locking side column groove is set on preceding lock core 6, on rear lock core 12 with the preceding lock core slide block chute 13 corresponding lock pin chutes 9 that are provided with, lock pin chute 9 has an end wall 10 at the afterbody of rear lock core, place slide block 1 in the slide block chute 13, locking side column 3 adopts inclined-plane 11 to contact with slide block 1, places lock pin 14 in the lock pin chute 9, between end wall 10 in lock pin chute 9 and the lock pin 14 lock pin back-moving spring 8 is set.

Tapered end shown in Figure 1 is the application of the utility model lock core clutch structure on the cylinder lock of existing deckle post with lock, and the concrete structure of this lock can be referring to the ZL99115581.5 patent documentation.During application, on should being used for the step of rear lock core 12 stop bits at lock body 2 afterbodys of tapered end with the lock pin chute 9 corresponding breach 7 of opening, lock pin 14 in the lock pin chute 9 can be matched with this breach 7, the length of slide block 1 is to determine like this: when locking side column 3 not the time, before and after the contact surface 16 of slide block 1 and lock pin 14 just is on the contact surface 17 of two lock cores with position that V-shaped groove 15 on the pellet shot from a slingshot 4 matches.

During locking, V-shaped groove 15 in the preceding lock core 6 on the V-shaped groove pellets shot from a slingshot 4 is out-of-line, locking side column 3 is radially outward backed down by pellet shot from a slingshot 4, slide block 1 that contacts with locking side column 3 inclined-planes 11 and lock pin 14 overcome the contact surface 16 that back-moving spring 8 makes both and are in the position that overlaps with front and back two lock core contact surfaces 17, and the end of lock pin 14 is in the position of matching with breach 7 on the lock body afterbody step, at this moment, preceding lock core 6 relative rear lock cores 12 can dally, rear lock core 12 fuses and can not rotate by lock pin 14 and lock body 2, and lock can not be opened; State when unblanking is seen Fig. 2, lock core 6 before key inserts, make 15 alignment of the V-shaped groove on the V-shaped groove pellet shot from a slingshot 4 in the lock core 6, locking side column 3 radially inwardly stretches under the effect of spring 5 in the V-shaped groove 15 of pellet shot from a slingshot 4, lock pin 14 and slide block 1 be axially inwardly motion under the effect of back-moving spring 8, position before both contact surfaces 16 are in the lock core 6, and the end of lock pin 14 be in lock body afterbody step on the position that is separated of breach 7, at this moment, preceding lock core 6 fuses by lock pin 14 and rear lock core 12, can rotate relative to lock body 2.

Tapered end shown in Figure 3 is the application that the utility model lock core clutch structure is locked at the blade of existing deckle post with lock, and the concrete structure of this lock can be referring to the ZL01240177.3 patent documentation.The idle rotation on-off structure of this tapered end and operating principle and tapered end shown in Figure 1 are identical.Slightly different is, what blade lock adopted is blade marble 18, is provided with V-shaped groove 19 in a side of blade marble 18, and the lock among the figure is in blocking, the V-shaped groove 19 of blade marble 18 1 sides is out-of-line, and locking side column 3 is in the position that can not match with the V-shaped groove 19 on the blade marble 18; After inserting key, V-shaped groove 19 places of blade marble one side in a straight line, locking side column 3 is in the position that can match with the V-shaped groove 19 on the blade marble 18, as shown in Figure 4.

As shown in Figure 5, the slide block in the utility model and the way of contact between the locking side column also can be that slide block 1 adopts inclined-plane 20 to contact with locking side column 3.

As Fig. 6, shown in Figure 7, slide block 1 also can be a spherical pieces.

When slide block 1 adopts spherical pieces, if lock core 6 is long, can also between lock pin 14 and spherical pieces, increase drive block 21, see Fig. 8, Fig. 9.

The utility model is fit to all cylinder locks that adopt side column locking structure and blade lock.
