Abstract
The utility model discloses an anti-shifting lock head, which comprises a lock head body and a lock cylinder structurally. The lock head body is internally provided with a lock cylinder hole. The lock cylinder is arranged in the lock cylinder hole in a clearance mode. The lock cylinder is internally provided with a key hole. The outside of the outer end part of the key cylinder is provided with a movable block which can move along the radial direction of the lock cylinder. The movable block and the periphery of the lock cylinder are relatively fixed. The movable block is stopped at the position of the key hole. Movable clamping structures are arranged between the movable block and the lock head body. The utility model also discloses a key for opening the lock head. A corresponding position on the key is provided with a through hole for accommodating the movable block. The movable block is arranged and the movable clamping structures are arranged between the movable block and the lock head body, and thus, when a non-key tool is utilized to technically open the lock head, the movable clamping structures can be clamped together to limit rotation of the lock cylinder relative to the lock head body so as to make the lock head have good anti-shifting effect and increase anti-twist performance of the lock head.
Description
Technical field
The utility model relates to a kind of anti-key of dialling tapered end and being used to open this tapered end.
Background technology
Safe-guard door lock mainly is made of tapered end, transmission mechanism and dead bolt, in the dead bolt except safety tongue, the unlatching of main dead bolt and oblique tongue mainly is to be realized opening by transmission mechanism by the shifting block on the tapered end, so the theftproof performance of tapered end has determined the safety in utilization of safe-guard door lock.The theftproof performance of tapered end is mainly reflected in anti-technical unlocking and anti-turning round on the performance, technical unlocking to tapered end is to utilize non-key-shaped tool that the pellet shot from a slingshot on the tapered end is stirred to put in place, realize then freely rotating in the lock core hole of lock core in tapered end, and make shifting block on the tapered end realize the unlatching of locking bolt by transmission mechanism; The anti-performance of turning round is to weigh an important indicator of lock core torsional strength, can utilize non-key-shaped tool to be inserted in the lock core keyhole in some cases, and this instrument applied certain peripheral force, and the pellet shot from a slingshot of being located between lock core and the tapered end is damaged, and the inserted sheet that stops steel ball is damaged, thereby can realize the unlatching of locking bolt.In the tapered end of existing structure, the outer end of the keyhole on the lock core directly exposes the outside at tapered end, is easy to stir instrument from the outer end insertion of keyhole like this pellet shot from a slingshot is stirred, the anti-weak effect of dialling of the tapered end of this structure.And when utilizing non-key-shaped tool to be inserted into to twist lock core by force in the lock core, it is also not fully up to expectations that tapered end anti-turned round performance.
The utility model content
For overcoming above-mentioned defective, the new technical issues that need to address of this practicality are: a kind of anti-key of dialling tapered end and being used to open this tapered end is provided, and anti-group of this tapered end is effective, and can increase the anti-performance of turning round of tapered end, when utilizing this key that tapered end is opened, can not have influence on the normal rotation of lock core.
In order to solve the technical problem, the technical solution of the utility model: a kind of anti-tapered end of dialling, comprise tapered end and lock core, be provided with lock core hole in the tapered end, lock core is located in the lock core hole with gap, is provided with keyhole in the lock core, being provided with in the outside, outer end of lock core can be along the directly upwards movable loose piece of lock core, the circumferential relative fixed of loose piece and lock core, loose piece is blocked in the position of keyhole, is provided with movable interface arrangment between loose piece and tapered end.This anti-tapered end of dialling is provided with described loose piece except the outer end at lock core, and is provided with between loose piece and tapered end outside the movable interface arrangment, and other structure of tapered end and common lock head structure are as good as.Inserting in the object process in keyhole, object can be pushed loose piece open, and makes loose piece upwards movable along the footpath of lock core.Anti-requirement of dialling structure should be at loose piece during in activity, and movable interface arrangment set between loose piece and the tapered end can be connected together mutually, can limit lock core after this activity interface arrangment is connected together and rotate with respect to tapered end; And after loose piece resetted, movable interface arrangment should be in the state of mutual disengaging.
This anti-tapered end of dialling also can be done following further optimization:
Described movable interface arrangment comprises lead of being located on the loose piece and the pilot hole of being located on the tapered end, and lead can be plugged in the pilot hole with gap.
The outer end of described lock core is fixed with cylindrical circular lock core cover, and described lead runs through the lock core cover wall body, and the end face of lock core cover is provided with position and the corresponding jack of described keyhole.
Be socketed with spring on the described lead, the two ends of spring act on respectively on lock core cover and the loose piece.
Be provided with some spacing convex bodys in lock core cover, described loose piece is between adjacent two spacing convex bodys.
Be provided with the little convex body of protrusion on the inner surface of lock core cover end, be provided with stopper slot on the direction of motion of loose piece upper edge loose piece, little convex body is plugged in the stopper slot.
Described loose piece and lead are two, and they are located on the lock core symmetrically, and the size that loose piece directly makes progress along lock core and the length sum of lead are equal to or slightly less than the radius of lock core hole.
Described loose piece is the inclined-plane towards the face in the outside, lock core outer end.
A kind of key that is used to open above-mentioned tapered end is to be provided with the open-work that is used to hold described loose piece in the corresponding position of key.The corresponding position of key, be meant key insert put in place in the keyhole after, loose piece just can be plugged in the described open-work.
Therefore, the beneficial effects of the utility model:
Be provided with described loose piece in the lock core keyhole outer end, and between loose piece and tapered end, be provided with movable interface arrangment, when tapered end being utilized non-key-shaped tool stir, this instrument will inevitably be inserted into from the outer end of keyhole in the keyhole, and loose piece is blocked in the position of keyhole outer end, non-key-shaped tool is inserted in the interior process of keyhole, can promote loose piece to the activity of lock core radial outside, loose piece is after activity, active card structure between loose piece and the tapered end can be connected together, thereby limit the circumferential rotation of lock core with respect to tapered end, even non-key-shaped tool can be stirred pellet shot from a slingshot set between lock core and the tapered end and put in place, also can be because of the mutual clamping of described movable interface arrangment, and lock core can not be rotated, guaranteed this anti-anti-effect of dialling of dialling tapered end.When utilizing non-key-shaped tool to be inserted in the keyhole and twisting lock core by force, also can be connected together mutually, and increase the anti-performance of turning round of this tapered end because of described movable interface arrangment.After utilizing described key to be plugged in the keyhole, loose piece can be inserted in the set on the key open-work, the initial position of loose piece on the lock core end can not change, movable interface arrangment set between loose piece and the tapered end is separated from mutually, can utilize the smooth unlatching of this key realization to this tapered end.
