Abstract
The utility model relates to a serpentiform theftproof lock, comprising a shell, a lock core in the shell and a key matching with a key hole in the lock core, wherein, the key hole has a serpentiform structure. Billiards are respectively arranged on the lock core along the circumference of the key hole. For the key hole has a serpentiform structure, the serpentiform key hole can effectively prevent various keys and special tools from entering into the key hole, so as to prevent the theft from using various special tools and keys to break the lock core and open the lock. For both the structure and fabrication of the key are complicated, the utility model can effectively prevent the theft form duplicating the key.
Description
Technical field
The utility model relates to a kind of snakelike theftproof lock.
Background technology
Cylinder lock commonly used at present, mostly be that the lock core front end is the key inlet port, establish key groove hole in the lock core, the slotted eye upper end is provided with the pellet shot from a slingshot hole, and lock core is positioned at lock tube, is provided with two-layer pellet shot from a slingshot successively in the pellet shot from a slingshot hole in the lock core, the rear end of two-layer pellet shot from a slingshot is provided with the spring roof pressure, the outer end of spring is enclosed on the lock body, and the rear end of lock core is provided with opening pin, is used to stir dead bolt and opens lock.The lock of this class formation makes gap between one deck pellet shot from a slingshot and the two layers of pellet shot from a slingshot just in time when lock core is parallel with the gap between the lock tube when on the key tooth, and key drives lock core and rotates and drive lock and open.Otherwise when two-layer pellet shot from a slingshot interlaces, lock core can not be rotated, if robber person destroys two-layer pellet shot from a slingshot easily under this state, its two-layer pellet shot from a slingshot is destroyed can open lockset.Also available hacksaw of robber person or electric drill directly destroy lock body and also lock can be opened simultaneously.Thereby such lockset anti-theft effect is not good.
Summary of the invention
The purpose of this utility model is to provide a kind of snakelike theftproof lock that can be effectively antitheft.
The purpose of this utility model is achieved in that this snakelike theftproof lock is to reach the key that matches with lock core keyhole by shell and assembling lock core in the enclosure to constitute, and said keyhole is a snakelike shape structure, and the pellet shot from a slingshot hole is divided into along on the lock core in key orifice ring week.
The technological progress that the utility model is obtained is: because keyhole is a snakelike shape structure, its forniciform snakelike keyhole can effectively stop various key and the special special tool(s)s of unblanking to enter in the keyhole, thereby can prevent effectively that robber person from using various special tool(s)s and key to destroy lock core or lock body and open lockset.The more complicated of the structure of this key processing has simultaneously prevented robber person's duplicating key effectively.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
Be that embodiment further specifies the utility model below with the accompanying drawing, as shown in Figure 1, this snakelike theftproof lock is to be made of shell 1 and the key 4 that lock core 2 reaches and lock core 2 keyholes 3 match that is assemblied in the shell 1, keyhole 3 is a snakelike cylindric guide groove, pellet shot from a slingshot hole 5 along keyhole 3 not the equidistant radial annular be divided on the lock core 2, be equipped with by the spring and the decorative pearl on top of an official cap in the pellet shot from a slingshot hole 5 and constitute pellet shot from a slingshot, the outer end extension in its pellet shot from a slingshot hole 5 is enclosed in the shell 1, pellet shot from a slingshot hole 5 can be designed to three to eight, and present embodiment is made as three pellet shot from a slingshot holes 5.On the lock core 2 of the entrance of said keyhole 3, be provided with and open location annular slotted hole 6, and on the lock core 2 of corresponding keyhole 3 ends, be provided with locating hole 7.The end of the cylindric snakelike key 4 that profile and keyhole 3 match is provided with the unlatching bulge loop 8 that matches with the unlatching of keyhole 3 entrance location annular slotted hole 6, is provided with keyhole 3 ends at the front end of key 4 simultaneously and is located at the locating shaft 9 that the locating hole 7 on the lock core 2 matches.
When this lockset uses, key 4 is inserted in the keyhole 3, make and open bulge loop 8 to going into to open in the positioning ring groove 6, the locating shaft 9 of its key 4 leading sections is to going in the locating hole 7, this moment is under the effect of key 4 curved surface circular arcs, pellet shot from a slingshot moves up, and makes pellet shot from a slingshot enter in the pellet shot from a slingshot hole 5, and pellet shot from a slingshot separates with pellet shot from a slingshot hole 5.Thereby lock core 2 is rotated, and locating shaft 9 promotes dead bolt, makes dead bolt produce displacement, realizes opening the function of lock.
