Abstract

The utility model provides a pin tumbler lock head with a double-raised-head cylindrical pin tumbler and a key thereof. The lock head is characterized in that at least two pin tumblers which are of double-raised-head cylindrical pin tumblers are arranged in a pin tumbler sliding groove which is longitudinally arranged above or below a key hole, and pin tumbler springs are arranged in the pin tumbler sliding groove between a lock core tail cover and pin tumblers; an unlocking sliding ring is arranged on the lock core, and a gap matched with an unlocking plunger on a fixed lock core sleeve is arranged at the front end of the unlocking sliding ring; the front raised head of each pin tumbler clings to the front end of the unlocking sliding ring, and the back raised head extends into the key hole; a locking bar is connected with the lock core sleeve; the lock core sleeve is arranged in a lock core shell, and the key matched with the lock head is in a flat shape; and step teeth matched with the front raised head of each pin tumbler of the lock core are arranged on the upper surface and the lower surface of the key. The lock can not be opened even if a tool is used to toggle the lock core, and only a corresponding key can be used to open the lock, thereby greatly improving the anti-theft performance and the security of the lock head.

Description

Be provided with the cylinder lock head and the key thereof of biconvex headpin shape pellet shot from a slingshot

Technical field

The utility model relates to the lock class, particularly a kind of cylinder lock head and key thereof that is provided with biconvex headpin shape pellet shot from a slingshot.

Background technology

As everyone knows, billiards lock structure is simple, theftproof is relatively good, makes easily again, therefore is used widely, no matter be that the lock that door lock, drawer-lock, lock and furniture use nearly all is a cylinder lock.The structure of cylinder lock had also been done many improvement in recent years, but the basic principle part does not still break away from traditional form of structure, especially its lock core and sword iron link together always, therefore, as long as managing rotational lock core can open lock, this is the defective of cylinder lock existence just, also is that many robbers adopt some special unlocking tools to make lock core rotate realization theft part by every means.

Summary of the invention

In order to solve the problems referred to above that existing cylinder lock exists, the utility model provides a kind of cylinder lock head and key thereof that is provided with biconvex headpin shape pellet shot from a slingshot, also can not open lock even adopt this cylinder lock to stir lock core with instrument when not having corresponding key.

Above-mentioned task realizes by this way: a kind of cylinder lock head that is provided with biconvex headpin shape pellet shot from a slingshot, include lock housing, lock core, pellet shot from a slingshot, marble spring and sword iron, it is characterized in that: also have the lock core cover, the slip ring of unblanking, the unblank bolt and the slip ring spring of unblanking, described pellet shot from a slingshot is a biconvex headpin shape pellet shot from a slingshot, its preceding plush copper and back plush copper difference symmetrical placement are in the preceding lower end and the upper end, back of column pellet shot from a slingshot body, the quantity of pellet shot from a slingshot is not less than 2 at least, length differs, be placed in respectively in the pellet shot from a slingshot sliding tray that the lower edge lock core is vertically offered on the keyhole shape cooperates with pellet shot from a slingshot, this pellet shot from a slingshot sliding tray front end sealing, the rear end seals with the lock core tail-hood, the outer end is opened wide, the inner is communicated with keyhole, marble spring is placed in the pellet shot from a slingshot sliding tray between lock core tail-hood and the pellet shot from a slingshot, the slip ring of unblanking is socketed on the lock core, its anti-rotation plush copper is placed in one of them pellet shot from a slingshot sliding tray, the lock core tail-hood that external diameter is identical, the unblank flange of slip ring and lock core front end is enclosed within the lock core cover, the lock core cover is connected with sword iron, have in the rear end of the slip cap of unblanking one be fixed in the breach that the bolt of unblanking that lock core puts cooperates, the slip ring spring of unblanking is placed on the lock core of unblanking between slip ring and the lock core flange, the elastic force of marble spring is greater than the elastic force of the slip ring spring of unblanking, the back plush copper of each pellet shot from a slingshot is close to the rear end of the slip ring of unblanking, its preceding plush copper extends in the keyhole, and the lock core cover is placed in the lock housing.

A key that cooperates with this tapered end, comprise a spoon handle and a spoon body, it is characterized in that described spoon as tabular, is having the ladder tooth that cooperates with plush copper behind each pellet shot from a slingshot of lock core on the last lower plane, all have the locating slot that cooperates with keyhole location fin in the both sides and the middle top and bottom of key.

The operating principle of this tapered end is such: in the time of in key does not insert keyhole, the back plush copper of each pellet shot from a slingshot is pressed on the rear end face of the slip ring of unblanking under the elastic force effect of marble spring; The bottom surface of plush copper and each ladder that rear end face just in time is close to key before each pellet shot from a slingshot in the time of in corresponding key inserts keyhole, when continuing to enforce key toward interior when mobile, each pellet shot from a slingshot moves simultaneously backward, thereafter plush copper breaks away from the constraint to the slip ring of unblanking simultaneously, the also translation backward under its spring force effect of slip ring of unblanking, when the breach of the slip ring of unblanking just in time fashionable with the bolt cover of unblanking, key, lock core just drives the lock core cover and rotates, and the sword iron that is attached thereto also rotates thereupon, and lock is opened.Why this tapered end plays effective antitheft effect and is that because the breach of the slip ring of unblanking is not enclosed within on the bolt of unblanking, lock core only can dally when the robber uses unlocking tool to stir the lock core rotation, can not drive the lock core cover and rotate, thereby lock can't be opened.Promptly use onesize key to insert in the keyhole, because each ladder tooth of key can't mate with plush copper before each pellet shot from a slingshot, pellet shot from a slingshot reach individually, and the back plush copper that can't realize each pellet shot from a slingshot is moved simultaneously, the slip ring of unblanking still is being in original position under indivedual marble spring elastic force effects, its breach does not contact the bolt of unblanking, therefore can not the rotation lock core retainer plate be opened by lock, have only the corresponding key of use to be inserted in the keyhole, the ladder tooth of its top and bottom is the preceding plush copper of corresponding each pellet shot from a slingshot just in time, pushes away the back plush copper translation simultaneously that makes each pellet shot from a slingshot again toward in and just can open lock.This shows that the anti-unlocking function of this tapered end is highly effective,, otherwise be difficult to lock is opened unless the robber will lock full destruction with the heavy industry tool.

In sum, this tapered end has been broken through the traditional structure form of existing cylinder lock, has solved its weak point effectively, has improved the theftproof performance of cylinder lock and the safety of use greatly.
