Description
Technical field
The utility model relates to a kind of tapered end that is used on the safe-guard door lock.
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 tapered end and lock core, lock core be axially arranged with keyhole, in tapered end, 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 tapered end 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, for the rotation of lock core in tapered end provides condition.For increasing the torsional strength between lock core and the tapered end, 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.
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, the torsional strength height.
The purpose of this utility model can realize by following technical proposal: a kind of safe-guard door lock tapered end, 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, 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.Vane hole can hold blade fully, is meant that the size of vane hole is slightly larger than or equals the size of blade, and after blade was positioned at vane hole fully, blade can not hinder the rotation of lock core in lock core hole.Under the effect of spring, when not having key to be inserted in the lock core, the convex body on the blade has the trend of stretching out towards the lock core outside, is connected in the draw-in groove by convex body, improves the torsional strength between lock core and the tapered end.Vane hole communicates with keyhole, one side of key is provided with some dentation convex bodys, have differential between these dentation convex bodys, after key is inserted in the keyhole, these dentation convex bodys touch with the bottom connection of blade U-shaped opening respectively, distance between the bottom of blade U-shaped opening and the blade openings end and the size of corresponding dentation convex body is corresponding on the key, in the time of in key is inserted into keyhole, dentation convex body on the key can make blade overcome spring elastic force and fully not in lock core, thereby can make lock core take place to rotate smoothly with respect to tapered end.
In this tapered end, place, the two ends of described U-shaped blade openings all is dihedral, and this corner ends forms described convex body.
In this tapered end, establish outstanding little convex body with respect to a side of openend on the described blade.
In this tapered end, on blade, be provided with semi-transparent little groove, in lock core, radially be provided with the inserted sheet that can be plugged in this little groove along it.
In this tapered end, it is protruding that the outside of described blade openings place one end is provided with card, an end of above-mentioned spring act on card protruding on.
In this tapered end, described keyhole is S-shaped along the cross section that makes progress perpendicular to lock core shaft.
Compared with prior art, the beneficial effects of the utility model are:
Lock core is provided with some described blades, blade is under the effect of spring, convex body on the blade can be connected in the draw-in groove set on the lock core hole inner peripheral surface, and convex body is connected in the draw-in groove, can increase between lock core and the lock core hole at the torsional strength that does not have under the key operated situation on the one hand; When lock core is stirred, remove the pellet shot from a slingshot that to stir in the lock core on the other hand, also will stir these blades, increased the anti-effect of dialling of safe-guard door lock.Semi-transparent little groove can be set on blade, so that the insertion of inserted sheet in the lock core does not just need to process separately more semi-transparent groove on pellet shot from a slingshot, simplify the manufacturing procedure of pellet shot from a slingshot, the torsional strength of pellet shot from a slingshot also can be guaranteed.
