Abstract
The utility model provides a double-safety theft-proof lock, which comprises a lock body 1, a cipher disc 2, a lock head 3 and a lock tongue 4. Two or over two ring lock pieces 10 are arranged on the cipher disc 2. The ring lock piece 10 is provided with a groove 9. A scab 8 which is matched with groove 9 is fixedly connected with the lock tongue 4 by a connecting rod 7. After the lock is locked, the cipher disc 2 is accurately rotated according to ciphers to make the groove 9 reached a correct position, the lock head 3 makes the scab 8 enter the groove 9 by that a key is used to push the lock tongue 4, and simultaneously the lock tongue 4 is retracted to the lock body 1. Other people can not open the double-safety theft-proof lock by using the key under the condition that the key is embezzled or the key is duplicated. Thereby, the utility model enhances a theft-proof performance and enhances safety coefficient.
Description
The utility model relates to a kind of double anti-theft safety lock.
Present widely used anti-theft safety lock, comprise lock body, dead bolt and tapered end, dead bolt is installed in the lock body, tapered end links to each other with dead bolt by transmission device, the lock body front end has perforation, and tapered end promotes transmission device by key, stretches out along the perforation of lock body front end thereby drive dead bolt, be stuck in the hole default on the doorframe, to reach the antitheft effect of locking.If but key is stolen or duplicate, other people are available key operated lockset.Therefore, existing anti-theft safety lock safety performance is relatively poor.
Even the purpose of this utility model is to provide a kind of double anti-theft safety lock that other people use key also can't open.
The technical scheme that realizes above-mentioned purpose is: comprise lock body, dead bolt, tapered end and combination disk, dead bolt is installed in the lock body, and tapered end links to each other with dead bolt by transmission device, and the lock body front end has perforation, tapered end can promote transmission device by key, thereby it is elastic along the perforation of lock body front end to drive dead bolt.Combination disk is installed on the lock body, and the annular locking plate more than two or two is arranged on the combination disk, all has groove on the every annular locking plate, and the projection that matches with the groove of annular locking plate is fixedly linked by connecting rod and dead bolt.During locking, tapered end promotes transmission device by key, stretches out along the perforation of lock body front end thereby drive dead bolt, is stuck in the hole default on the doorframe, and projection breaks away from the groove on the annular locking plate simultaneously.At this moment the rotational password dish makes the groove on the annular locking plate leave existing position, and the edge of annular locking plate withstands projection, even make dead bolt also can't withdraw backward under the drive of tapered end.When lockset is opened, earlier according to the correct rotational password dish of setting of password, make the groove of every annular locking plate all aim at the tram, driving tapered end with key again rotates, thereby promotion transmission device, drive dead bolt backward along lock body front end perforation withdrawal, projection enters in the groove on the annular locking plate, and dead bolt is withdrawn in the lock body.
Because lockset of the present utility model must earlier correct rotational password dish when opening, and could open tapered end with key, therefore, even key is stolen or duplicate, other people also can't open, thereby can improve anti-theft capability greatly, strengthen safety factor.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a scheme of installation of the present utility model.
Fig. 2 is an internal construction schematic diagram of the present utility model.
The utility model is made up of lock body 1, combination disk 2, tapered end 3 and dead bolt 4, and combination disk 2 and tapered end 3 are installed in respectively on the lock body 1, and dead bolt 4 is movably arranged in the lock body 1 by supporting plate 11, and links to each other with tapered end by transmission device 6.Lock body 1 front end has perforation 5, and tapered end 3 can promote transmission device 6 by key, thereby it is elastic along the perforation 5 of lock body 1 front end to drive dead bolt 4.Combination disk 2 has the annular locking plate 10 more than two or two, and annular locking plate 10 is movably arranged in the lock body 1.All have groove 9 on the every annular locking plate 10, the projection 8 that cooperates with groove 9 is fixedly linked by connecting rod 7 and dead bolt 4.
During locking, tapered end 3 promotes transmission device 6 by key, stretches out forward along the perforation 5 of lock body 1 front end thereby drive dead bolt 4, and in the hole of presetting on card and the doorframe, projection 8 leaves groove 9 simultaneously.This moment, the rotational password dish 2, made the groove 9 on the annular locking plate 10 leave existing position, and the edge of annular locking plate 10 withstands projection 8, even make dead bolt 4 also can't be withdrawn into backward in the lock body 1 under the promotion of tapered end 3, reached the effect of double insurance.
During unlatching, earlier according to the correct rotational password dish of setting 2 of password, make the groove 9 of every annular locking plate 10 all arrive the tram, relend by key turns tapered end 3, tapered end 3 promotes dead bolt 4 by transmission device 6 and contracts backward along perforation 5, projection 8 enters in the groove 9, and dead bolt 4 is got back in the lock body 1 simultaneously.
