Abstract
The locking head for cylinder lock includes one lock body, one lock core and one locking side pin inside the lock core to match the V-slotted marble. The lock core has a runner communicated with the locking side pin, a sliding block inside the runner contacting with the locking side pin, a block restoring spring. The lock body has notch in the tail for matching the sliding block. The present invention realizes the combination and separation of the lock core and the lock body by means of the axial motion of the sliding block, and may have locking head with reduced diameter, less material consumption and lowered production cost.
Description
Technical field
The invention belongs to mechanical lock, relate to a kind of tapered end of cylinder lock.
Background technology
Relating to aspect the tapered end of cylinder lock, the tapered end that has a kind of pellet shot from a slingshot that utilizes band V-shaped groove in locking side column and the lock core to cooperate to come control lock to open and close in the prior art is seen the ZL99115581.5 patent documentation.Although this lock has the characteristics of theftproof and anti-skilled unlocking preferably.But, also come with some shortcomings.Because locking side column stops lock core to rotate by extending into towards the lock core radial direction in the lock body, this just requires the diameter of lock body bigger, causes using more material, and cost of production is increased.
Summary of the invention
The objective of the invention is at above-mentioned situation, provide a kind of material of relatively saving, the tapered end of the cylinder lock that reduces production costs.
The present invention seeks to realize like this: the tapered end of cylinder lock comprises lock body, locking side column in lock core and the lock core, V-shaped groove pellet shot from a slingshot in locking side column and the lock core matches, the chute that communicates with the locking side column groove is set on lock core, chute extends to the afterbody of lock core vertically and an end wall is arranged, place sliding shoe in the chute, contact for the inclined-plane between sliding shoe and the locking side column, be provided with between end wall in chute and the sliding shoe between the sliding shoe back-moving spring, sliding shoe in the corresponding breach that has with the lock core chute on the lock body afterbody is used for the step of lock core stop bit, chute can match with this breach.
The side column tapered end is being unblanked or during locking, locking side column can be moved in the radial direction at lock core, owing to be provided with sliding shoe in lock core, sliding shoe takes the inclined-plane to contact with locking side column in the axial direction.Therefore when locking side column is done radial motion, just its radial motion can be changed into the axially-movable of sliding shoe by its inclined-plane that contacts with sliding shoe, match with breach on the lock body afterbody step by sliding shoe again, reach the purpose that switching is locked.
The utility model is owing to utilize sliding shoe motion in the axial direction, the combination that realizes lock core and lock body with separate, finish equally unblank and the function prerequisite of locking under, the diameter that has the side column tapered end now can be reduced.Diameter as existing tapered end is generally 17mm, adopt tapered end of the present invention after, the tapered end diameter only needs 15mm.Reducing of tapered end diameter means and can save material, reduces production costs.
Further specify technical solution of the present invention below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the different user mode schematic diagrames of Fig. 1.
The specific embodiment
See Fig. 1, the tapered end of cylinder lock of the present invention is based on the disclosed tapered end of ZL99115581.5 patent documentation, comprise lock body 2, locking side column 3 in lock core 6 and the lock core 6, V-shaped groove 12 on the pellet shot from a slingshot 4 in locking side column 3 and the lock core 6 matches, the chute 9 that communicates with the locking side column groove is set on lock core 3, chute 9 extends to the afterbody of lock core vertically and an end wall 10 is arranged, place sliding shoe 1 in the chute 9, contact for inclined-plane 11 between sliding shoe 1 and the locking side column 3, between end wall 10 in chute 9 and the sliding shoe 1 sliding shoe back-moving spring 8 is set, with the lock core chute 9 corresponding breach 7 that have, the sliding shoe 1 in the chute 9 can match with this breach 7 on lock body 2 afterbodys are used for the step of lock core stop bit.
Operating principle:
As shown in Figure 1, during tapered end locking states of the present invention, V-shaped groove 12 in the lock core 6 on the V-shaped groove pellet 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, the sliding shoe 1 that contacts with locking side column 3 inclined-planes 11 overcomes back-moving spring 8 makes its end be in the position of matching with breach 7 on the lock body afterbody step, because sliding shoe 1 is in the chute 9 and the breach 7 on the lock body afterbody step of lock core 6 simultaneously, lock core 6 and lock body 2 are connected as a single entity, therefore, lock core 6 can not rotate, and lock can not be opened; State when unblanking is seen Fig. 2, key inserts lock core 6, make 12 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 12 of pellet shot from a slingshot 4, sliding shoe 1 in the chute 9 axial inclined-plane 11 along locking side column 3 under the effect of back-moving spring 8 axially inwardly moves, break away from the breach 7 on the lock body afterbody step simultaneously, lock core 6 can rotate.
Claims (1)
1, a kind of tapered end of cylinder lock comprises lock body, locking side column in lock core and the lock core, V-shaped groove pellet shot from a slingshot in locking side column and the lock core matches, it is characterized in that on lock core, being provided with the chute that communicates with the locking side column groove, chute extends to the afterbody of lock core vertically and an end wall is arranged, place sliding shoe in the chute, contact for the inclined-plane between sliding shoe and the locking side column, the sliding shoe back-moving spring is set between end wall in chute and the sliding shoe, sliding shoe in the corresponding breach that has with the lock core chute on the lock body afterbody is used for the step of lock core stop bit, chute can match with this breach.
