Abstract
The utility model relates to a torsion-proof locking head which comprises a locking head body. A lock core hole is formed in the locking head body; a lock core is arranged in the lock core hole; a keyhole is formed in the lock core; an insertion piece which can move in a radial direction of the lock core is arranged on the lock core; a movable sheet is arranged on the lock core in clearance; the movable sheet is perpendicular to an axial direction of the lock core and can move in the axial direction perpendicular to the lock core; a small convex body is formed at the tip of the movable sheet in the movable direction; a locating convex body used for matching with a key is formed on the movable sheet; after the key is inserted into the keyhole fully, the movable sheet and the small convex body are contained in the lock core fully; and a position-limiting groove used for matching with the small convex body is formed on an inner wall of the lock core hole. A protruded pushing convex body which is matched with the locating convex body is formed on the surface of the key. The small convex body formed on the movable sheet can help to limit the rotation of the lock core in the locking head body, and the movable sheet is hard to be pushed in place by other tools, so that the torsion-proof performance of the torsion-proof locking head is good.
Description
Technical field
The key that the utility model relates to a kind of anti-twistlock head and matches with it.
Background technology
Tapered end is the vitals of door lock, plays locking bolt on the opening and closing door lock.The structure of existing safe-guard door lock tapered end comprises tapered end, be provided with lock core hole in the tapered end, be provided with lock core in the lock core hole, be provided with keyhole in the lock core, lock core is provided with can be along the inserted sheet of lock core radial direction activity, the outside at inserted sheet also is provided with steel ball, and the inwall in tapered end internal cylinder hole is provided with and is used for the groove that matches with steel ball.Be provided with several pellet shot from a slingshot holes in tapered end, be provided with in the pellet shot from a slingshot hole and have differential pellet shot from a slingshot, the end of pellet shot from a slingshot extend in the keyhole, and under the effect of spring force, the end roof pressure of pellet shot from a slingshot is in the bottom of keyhole.When inserting from the socket position of keyhole with the differential key that adapts of pellet shot from a slingshot in the tapered end, the end of key compressing pellet shot from a slingshot, pellet shot from a slingshot is subjected to displacement in the pellet shot from a slingshot hole, set groove moves to the position of inserted sheet on the pellet shot from a slingshot outer peripheral face, lock core is when rotating in tapered end under the drive of key, steel ball meeting roof pressure inserted sheet enters in the groove set on the pellet shot from a slingshot inserted sheet, and lock core can freely rotate in tapered end.The tapered end of this structure is to utilize pellet shot from a slingshot and steel ball that lock core is limited with respect to the rotation between the tapered end when door lock locks, and it is better that lock core anti-turned round function.But its shortcoming is: if from the lock core the position of keyhole all pellets shot from a slingshot stir put in place after, just can realize lock core with respect to the accessible rotation of tapered end, this for have professional level the burglar difficulty be not very big.
The utility model content
The purpose of this utility model is: a kind of anti-performance, anti-good anti-twistlock head of performance of dialling turned round that increase is provided.
Another purpose of the present utility model is: provide a kind of and be used for and prevent turning round, anti-dial the key that the good tapered end of property matches.
The purpose of this utility model can realize by following technical proposal: a kind of anti-twistlock head, comprise tapered end, be provided with lock core hole in the tapered end, be provided with lock core in the lock core hole, be provided with keyhole in the lock core, lock core is provided with can be along the inserted sheet of lock core radial direction activity, on lock core, be provided with activity template with gap, activity template is axial perpendicular to lock core, and can be along axial direction activity perpendicular to lock core, the end of activity template activity direction is provided with little convex body, activity template is provided with and is used for the location convex body that matches with key, after key was inserted in the keyhole fully, activity template and little convex body were contained in the lock core fully, were provided with to be used for the stopper slot that matches with little convex body on the lock core hole inwall.During the lock-out state of locking bolt, the stopper slot on the lock core hole inwall is positioned at the little convex body position on the activity template on tapered end is in safe-guard door lock.Can be provided with spring between activity template and the lock core, the outside and stopper slot that spring can impel little convex body to stretch out lock core are plugged on together.At activity template is under the situation of multi-disc, also spring can be set between activity template and the lock core, but activity template is on the state of being free to slide, and is not having key to be inserted under the situation in the lock core hole, and the little convex body on some activity templates can be inserted in the stopper slot.Activity template and little convex body can be received in the lock core fully, are meant that the size sum of activity template and little convex body should be less than or equal to the set cavity size that is used to hold activity template on the lock core.After key is inserted in the keyhole fully, has the structure that matches with spacing convex body on the activity template on the key, the size of this structure is corresponding with the size of spacing convex body, and when both matched, the little convex body on the activity template was retracted in the lock core and with described stopper slot and is separated.
This anti-twistlock head also has following improvement:
Described little convex body is two, and they are separately positioned on the both ends of activity template activity direction, and described stopper slot is two.
Described activity template is a plurality of, and they are arranged in juxtaposition along the axial direction of lock core.
The size of these activity templates and little convex body equates.
Be equipped with the recess of degree of depth unanimity on all activity templates, these recesses are towards described inserted sheet.
Described activity template is provided with the through hole of sealing, and described location convex body is positioned at through hole.
A kind of key of matching with above-mentioned anti-twistlock head of being used for comprises handle and key copperhead, and the surface of described key copperhead is provided with the promotion convex body, promote convex body be used for described activity template on spacing convex body match.It is corresponding with the size of spacing convex body to promote convex body, and when both matched, key made activity template and little convex body be received in the lock core fully.
Described promotion convex body is a plurality of, and these lateral surfaces that promote convex body are interconnected to form bending curved surface more than.
Compared with prior art, the beneficial effects of the utility model are:
Lock core is provided with activity template, and the little convex body on the activity template can be plugged in the stopper slot set on the inwall of tapered end upper lock core hole, to participate in the limiting rotation of lock core in tapered end, has increased the anti-function of turning round of tapered end.Activity template is movable on lock core, activity template and on little convex body when being fully retracted in the lock core, feature clearly not, this is unfavorable for using the instrument beyond the key to move into place by activity template, has increased the anti-performance of dialling of tapered end.
