Description

The anti-tapered end of dialling

Technical field

The utility model relates to a kind of anti-tapered end of dialling that is used on the safe-guard door lock, be provided with in the lock core of this tapered end some can be along the blade that moves perpendicular to the lock core axial direction.

Background technology

Tapered end is the vitals in the safe-guard door lock, also be provided with transmission mechanism and dead bolt in the safe-guard door lock, tapered end is provided with shifting block, under the drive of key, shifting block makes dead bolt do to stretch out or be retracted into the action of lock body by transmission mechanism, to finish locking and the unlatching to security door.The structure of tapered end comprises lock body and lock core, lock core be axially arranged with keyhole, in lock body, be provided with lock core hole, lock core is plugged in the lock core hole, lock core can rotate in lock core hole under the drive of key.Existing most tapered end all is that some pellets shot from a slingshot are set between lock body and lock core, have between these pellets shot from a slingshot differential, in key is plugged into keyhole after, pellet shot from a slingshot can move axially, and removes the qualification that lock core is rotated.For increasing the torsional strength between lock core and the lock body, in lock core body, also be provided with inserted sheet along its radial direction, after in key is inserted into keyhole, pellet shot from a slingshot in the lock core can be in a fixing position under the effect of key, can be provided with a semi-transparent groove on the outer peripheral face of each pellet shot from a slingshot, this moment, these semi-transparent grooves can stably be in same position, so that enter in the semi-transparent groove under the shearing force effect that inserted sheet forms, thereby be convenient to relatively stable rotation between lock core and the tapered end between lock core and tapered end.The tapered end of this structure is owing to need be provided with semi-transparent groove on pellet shot from a slingshot, processing is inconvenient, can have influence on the torsional strength of pellet shot from a slingshot.And its anti-group effect is bad, causes the anti-theft effect of safe-guard door lock poor.

A kind of anti-tapered end of dialling has also appearred on the market now, its structure comprises lock body and lock core, be provided with lock core hole in the lock body, lock core is plugged in the lock core hole, the axial of lock core is provided with keyhole, and described lock core is provided with some vane holes, and these vane holes are axial perpendicular to lock core, and distribute along the axially spaced-apart of lock core, vane hole communicates with keyhole; Be provided with the U-shaped blade vane hole internal clearance, vane hole can hold described blade fully, be provided with spring between blade and the lock core, blade is provided with the convex body that can be projected into the lock core outer peripheral face outside, in the inner peripheral surface upper edge of lock core hole its be axially arranged with can with the convex body draw-in groove of clamping mutually.This anti-complex structure of dialling tapered end is to the assembling inconvenience of blade.

The utility model content

The purpose of this utility model is to provide a kind of safe-guard door lock tapered end, and anti-group of this tapered end is effective, simple in structure, is convenient to assembling.

The purpose of this utility model can realize by following technical proposal: a kind of anti-tapered end of dialling, comprise lock body and lock core, be provided with lock core hole in the lock body, lock core is plugged in the lock core hole, and the axial of lock core is provided with keyhole, is provided with some blades in the described lock core, blade can move along the axial direction perpendicular to lock core in lock core, these blades distribute along the axially spaced-apart of lock core, and blade is provided with the little convex body that extend in the keyhole, is provided with recess on a blade side relative with little convex body.Radially also be provided with inserted sheet along it in the lock core, be provided with spring in the inboard of inserted sheet in the lock core, the outside in inserted sheet on the lock core is provided with ball, or the lateral surface of inserted sheet is level and smooth cambered surface.At the inner peripheral surface of the lock body lock core hole stopper slot that is axially arranged with along lock core hole, ball is pressed to the inner peripheral surface of lock core hole under the effect of inserted sheet.After in ball is plugged into stopper slot, ball also can limit lock core with respect to the rotation of lock body.To this anti-dial that tapered end opens be provided with crank slot on the key, relative position on the shape of crank slot and the blade between little convex body and the recess is corresponding, after key is plugged in the lock core hole, crank slot is by matching with little convex body on the blade, and make vanes fixed in certain position, all blades are in the qualification effect of key crank slot, recess on the blade all is positioned at the dorsal part of inserted sheet, during key, under the effect of shearing force, ball can be pressed to recess on the blade to inserted sheet, thereby vacates the position for ball enters into lock core inside, lock core can freely rotate in lock core hole, thereby can open door lock.

On lock core, be provided with the tank consistent, be equipped with a described blade in each tank with described lobe numbers.Tank also is axial vertical with lock core, and tank generally is semi-transparent to lock core inside from plug face, and this tank is easy to process.

Outer port part on tank is provided with the block body that is used to limit blade.This block body is used to make blade stably to remain in the tank.

It is axially arranged with groove in lock core outer peripheral face upper edge, and groove and described tank intersect, and described block body is embedded in the groove.Block body generally is made of plastics, and block body is embedded in the groove, makes block body can not hinder the smooth and easy rotation of lock core.

It is protruding that described block body is provided with the some cards that are connected as a single entity with it, and it is consistent to block protruding number with described blade, and each blocks protruding being embedded in the tank.Block protruding being embedded in the tank, improved the connectivity robustness between block body and the lock core, good to the blocking effect of blade.

Described block body is two, and these two block bodies upwards were provided with at interval in the week of lock core.Two block bodies limit blade, have improved the stability that block body limits blade.

The both ends of described two block bodies are provided with the connector that is connected as a single entity with it respectively.Connector connects two block bodies as a whole, has made things convenient for block body is embedded in the lock core.

Compared with prior art, the beneficial effects of the utility model are:

Blade is provided with little convex body and recess, little convex body by with cooperating between the crank slot realize the qualification of recess position on the key, need in lock core, not be provided for promoting the spring of the motion of blade, make this lock head structure simple, convenient for assembly.Only little convex body and recess need be set on the blade, the structure of blade itself is also fairly simple, and processing of leaves is convenient.
