Abstract
The invention provides an antitheft lock cylinder assembly which comprises a key and a lock cylinder. The lock cylinder is composed of a lock cylinder body and a lock liner. A plurality of marble devices are arranged between the lock cylinder body and the lock liner, each marble device consists of a first marble, a second marble, a lock spring and a plug, and the first marble is arranged in the lock liner. The key sequentially consists of a handle, a rotation head and an insert head. The key hole of the lock liner is a flat cavity, an opening of the flat cavity is provided with a rotary matching cavity, the thickness of the flat cavity is 0.15-0.65mm, and the head of the first marble is arranged in the flat cavity and is conical. The rotation head is matched with the rotation matching cavity, the thickness of the insert head is matched with the size of the flat cavity, and a matching gap ranges from 0.05mm to 0.15mm; and the insert head is provided with holes different in size at the positions corresponding to the marble devices. The interior thickness of the key hole of the lock liner ranges from 0.l5mm to 0.65mm, the existing theft unlocking tools cannot extend deeply, and theft unlocking is prevented.
Description
Technical field
The present invention is a kind of anti-theft lock assembly.
Background technology
Existing lock core, key have certain thickness, so present pirate of the open lock tool can go deep in keyhole and have certain pellet space of stirring, stir pellet and reach the object of unblanking.
Summary of the invention
The present invention proposes a kind of anti-theft lock assembly, the thickness that changes current lock core keyhole, by the in the past thick thinner keyhole that changes into, key by thick key in the past change into use good toughness, hardness is high, repeatability is strong, the steel disc of high abrasion, be provided with hole not of uniform size and realize corresponding with pins pellet, unblank thereby realize, reach the effect of antitheft.
For this reason, technical scheme of the present invention is: a kind of anti-theft lock assembly, comprise key, lock core, lock core is made up of plug body, lock gall, between plug body, lock gall, be provided with many group cylinder devices, every group of cylinder device is made up of successively the first pellet, the second pellet, locking spring, plug, and the first pellet is positioned at lock gall; Key is made up of successively handle, rotary head, insert head, it is characterized in that: the keyhole of lock gall is flat lumen, the oral area of flat lumen is provided with the chamber that is rotatably assorted, and the thickness of flat lumen is 0.15-0.65 millimeter, the head of the first pellet is positioned at flat lumen, and the head of the first pellet is tapered;
The rotary head of key matches with the chamber that is rotatably assorted of keyhole, and thickness and the flat lumen of insert head match, and fit clearance is between 0.05-0.15 millimeter; Correspondingly with the position of every group of cylinder device on insert head be respectively equipped with vestibule not of uniform size.
The material that described insert head adopts is austenitic alloy steel or chromium plating spring steel.
Beneficial effect: because the keyhole inner thickness of lock gall is between 0.15-0.65 millimeter, existing pirate of the open lock tool cannot go deep in it, thereby reaches the effect of antitheft; When use, key inserts in keyhole, and by vestibule jack-up pellet not of uniform size, realization is unblanked; This practicality is easy to use, greatly improves its safety.

Fig. 1 is the structure chart of key in the present invention.
Fig. 2 is the structure chart of lock core in the present invention.
Fig. 3 is the structure chart of the first pellet in the present invention.
Fig. 4 is the structure chart of the second pellet in the present invention.
The specific embodiment
As shown in Figure 1 and Figure 2, further describe the present invention as follows:
A kind of anti-theft lock assembly, comprise key, lock core, lock core is made up of plug body 5, lock gall 13, between plug body 5, lock gall 13, be provided with many group cylinder devices, every group of cylinder device is made up of successively the first pellet 9, the second pellet 8, locking spring 7, plug 6, and the first pellet 9 is positioned at lock gall; Key is made up of successively handle 1, rotary head 2, insert head 3;
The keyhole of lock gall 13 is flat lumen 11, and the oral area of flat lumen 11 is provided with the chamber 12 that is rotatably assorted, and the thickness of flat lumen 11 is 0.15-0.65 millimeter, and it is tapered that the head 9 of the first pellet is positioned at the head of flat lumen 11, the first pellets 9;
The rotary head 2 of key matches with the chamber 12 that is rotatably assorted of keyhole, and the thickness of insert head 3 and flat lumen 11 match, and fit clearance is between 0.05-0.15 millimeter; On insert head with the corresponding vestibule not of uniform size 4 that is respectively equipped with in position of every group of cylinder device;
Lock gall 13 is in transmission connection with dead bolt 10.
As shown in Figure 3, the first pellet 9 main bodys are rectangular shapes, just the tapered 9a of head; , the head of the first pellet 9 is provided with inclined plane along the both sides correspondence of (lock gall) keyhole length direction, becomes taper, is convenient to coordinate with the vestibule of key.
As shown in Figure 4, the second pellet 8 is rectangular shapes.
The insert head 3 of key uses good toughness, hardness is high, repeatability is strong, the steel disc of high abrasion is made, for example: austenitic alloy steel or chromium plating spring steel.
Antitheft principle: because the keyhole inner thickness of lock gall is between 0.15-0.65 millimeter, existing pirate of the open lock tool cannot go deep in it, thereby reaches the effect of antitheft.
