Abstract

The utility model discloses a lock core, comprising a core body and a shell sleeved outside the core body, wherein the core body is provided with a swastika-shaped keyhole, the four sidewalls of the keyhole and shell are provided with four rows of marble holes. The quantity and position of the marble holes and the length of marbles embedded in the marble holes of the lock core form four sets of unlocking passwords. When conditions of four sets of unlocking passwords are all met, the lock can be opened, thus greatly lowering the mutual-opening rate. The utility model has the advantages of simple structure, close fit, strong anti-theft performance and high reliability.

Description

A kind of lock core

Technical field

The utility model relates to a kind of lockset, particularly a kind of lock core.

Background technology

Lockset is as a kind of security instrument commonly used, and its reliability is people's attention extremely, and along with developing rapidly of electronic information technology, traditional mechanical lock is constantly to high-tech, intelligent direction development, as electronic lock, remote control lock, Fingerprint Lock etc.Yet,, can not replace the status of traditional mechanical lock because this class lockset expensive price, fault rate height such as electronic lock, remote control lock, Fingerprint Lock can not be accepted by general customer.In order to improve the reliability of mechanical lock, mechanical lock miscellaneous has appearred on the market, however these locksets or complex structure, fault rate height, or the mutual opening rate height, reliability is not high, can not satisfy the needs in market.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of simple in structure, institute's core that reliability is high.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of lock core comprises lock core body and is set in the outer shell of lock core body that described lock core body is provided with keyhole, described keyhole be "

" font; be provided with the some lock core marble holes that adapt with keyhole around the described lock core body; shell is provided with four exclusive shell pellet shot from a slingshot holes accordingly; hoodle is installed all in described four row's lock core marble holes and the shell pellet shot from a slingshot hole and with the lock core spring of hoodle top to the keyhole side, the hoodle in key inserts rear lock core pellet shot from a slingshot hole is terminal concordant with the external surface of lock core body.

As further improvement of the utility model, quantity, the position in described wherein one group of lock core marble hole that is oppositely arranged and shell pellet shot from a slingshot hole and to be embedded in the length of hoodle in the lock core marble hole identical.

The beneficial effects of the utility model are: keyhole of the present utility model for "

" font; the four sides sidewall of keyhole and shell are provided with four row pellet shot from a slingshot holes; the quantity in pellet shot from a slingshot hole, position and the length that is embedded in hoodle in the lock core marble hole constitute four groups of unlocking ciphers; need to satisfy simultaneously the condition of four groups of unlocking ciphers when unblanking; just lock can be opened; greatly reduce mutual opening rate, have simple in structure, cooperate closely, theftproof performance is strong, the reliability advantages of higher.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model;

The specific embodiment

With reference to Fig. 1, a kind of lock core comprises lock core body 1 and is set in the outer shell 2 of lock core body 1 that described lock core body 1 is provided with keyhole 3, described keyhole 3 be "

" font; be provided with the some lock core marble holes 4 that adapt with keyhole 3 around the described lock core body 1; shell 2 is provided with four exclusive shell pellet shot from a slingshot holes 5 accordingly; hoodle 6 all is installed and in described four row's lock core marble holes 4 and the shell pellet shot from a slingshot hole 5; hoodle 6 in key inserts rear lock core pellet shot from a slingshot hole 4 is terminal concordant with the external surface of lock core body 1; get final product rotation lock core body 1 with the lock core spring 7 of hoodle 6 tops to keyhole 3 sides, drive the action of dead bolt assembly, after extracting key, hoodle 6 terminal uneven, hoodle 6 is inserted between lock core marble hole 4 and the shell pellet shot from a slingshot hole 5, and locking lock core body 1 makes lock core body 1 opposite shell 2 not rotatable.Because the four sides sidewall of keyhole and shell are provided with four row's pellet shot from a slingshot holes, the quantity in pellet shot from a slingshot hole, position and be embedded in that the length of hoodle constitutes four groups of unlocking ciphers in the lock core marble hole, need to satisfy simultaneously the condition of four groups of unlocking ciphers when unblanking, just lock can be opened, greatly reduce mutual opening rate, have simple in structure, cooperate closely, theftproof performance is strong, the reliability advantages of higher.

As further improvement of the utility model, quantity, the position in described wherein one group of lock core marble hole that is oppositely arranged 4 and shell pellet shot from a slingshot hole 5 and to be embedded in the length of hoodles 6 in the lock core marble hole 4 identical, when mounted, one group of identical above-below direction of unlocking cipher is installed, made things convenient for the insertion of key and opened lockset.
