Abstract
The utility model relates to a combination anti-theft lock, in which a U-shaped lock rod (1) is hinged with a lock body (2) through a hinge pin hole (3), a combination dialing disc (8) is arranged inside the lock body (2), and a key lock core (6) is arranged at the right end of the lock body (2). The surface of the combination dialing disc (8) is provided with a combination boss (13), on which numbers are marked. An inner bore dialing disc (11) is arranged inside the combination dialing disc (8). When inputting a correct combination and a right key, the lock can be unlocked. After the anti-theft lock is unlocked, the combination dialing disc (8) moves to the right, and thereby the combination for unlocking the key can be changed. The combination anti-theft lock employing two unlocking ways, the key and the combination, not only increases safety of the anti-theft lock, but also can freely change the combination for unlocking, thereby effectively resolving the trouble that stealing is easy to happen after the code combination is known by others.
Description
Affiliated technical field
The utility model relates to a kind of theftproof lock, especially a kind of puzzle theft-proof lock.
Background technology
At present, known theftproof lock is all opened by key, and common metal key is duplicated easily, causes theftproof lock can not play higher safety performance.The theftproof lock of another kind of type, it is to be opened by password, though theftproof performance is better, its password does not have alterability, causes this lock to be used the back password by others and is grasped by its user yet, security performance reduces.
Summary of the invention
In order to overcome the deficiency of existing theftproof lock poor safety performance, the utility model provides a kind of puzzle theft-proof lock, this lockset has key operated and password is opened two kinds of modes of unblanking, and password can be changed, so not only can guarantee the safety of lockset after the key loss, thoroughly solve trouble and worry after password is obtained by others but also can arbitrarily change the lockset password.
The technical scheme that its technical problem that solves the utility model adopts is: U-shape sword iron (1) is by hinge pin hole (3) and lock body (2) hinge mutually, and password dial (8) is positioned at lock body (2) central inner, and key core (6) is positioned at the right-hand member of lock body (2).Active pin shaft (7) from left to right passes six password dials (8) successively and locking bar groove (4) is connected with key core (6) at last, and active pin shaft (7) restriction U-shape sword iron (1) can not move up and down it.Password dial (8) surface is provided with password boss (13), is marked with numeral at password boss (13).Endoporus dial (11) is positioned at the inside of password dial (8), and is meshed by the inner tooth platform of tooth platform on the outer rim and password dial (8), and endoporus dial (11) center is provided with endoporus dial centre bore (12).Password dial central axis (18) outer rim is provided with active pin shaft zigzag boss (17), and password dial central axis (18) is connected with active pin shaft (7) by axle head active pin shaft boss (14).When unblanking, needing to stir password dial (8) with hand earlier makes six password dials present the password of predefined six figure places, at this moment, groove on six endoporus dial centre bores (12) is on same branch line, then key (5) is inserted in the key core (6) and screw key (5), like this password dial central axis (18) just can be under the drive of key core (6) right motion vertically, thereby active pin shaft groove (16) aligns with locking bar groove (4), make active pin shaft (7) can not limit moving up and down of U-shape sword iron (1), promptly lock is opened.Have only when password input that lock just can be opened when correct and key was correct, strengthened the security performance of theftproof lock.Simultaneously, after theftproof lock was unlocked, password dial central axis (18) moved right, and password dial this moment (8) also can so just can realize changing the purpose of unlocking cipher by changing password dial (8) to the right with endoporus dial (11) relative position.
The beneficial effects of the utility model are, adopt key and two kinds of opening ways of password, have not only increased the safety of theftproof lock, and unlocking cipher can arbitrarily change, from and thoroughly solved password and known back stolen trouble and worry easily by others.

The specific embodiment
In Fig. 1, U-shape sword iron (1) is by hinge pin hole (3) and lock body (2) hinge mutually, and password dial (8) is positioned at lock body (2) central inner, and key core (6) is positioned at the right-hand member of lock body (2).
In Fig. 2, active pin shaft (7) from left to right passes six password dials (8) successively and locking bar groove (4) is connected with key core (6) at last, and active pin shaft (7) restriction U-shape sword iron (1) can not move up and down it.Back-moving spring (9) is positioned at bearing pin loose slot (10) inside, and contacts with password dial central axis (18) left side.
In Fig. 3, password dial (8) surface is provided with password boss (13), is marked with numeral at password boss (13).
In Fig. 4, Fig. 5, endoporus dial (11) is positioned at the inside of password dial (8), and is meshed by the inner tooth platform of tooth platform on the outer rim and password dial (8), and endoporus dial (11) center is provided with endoporus dial centre bore (12).
In Fig. 6, the length of the tooth platform on endoporus dial (11) outer rim only is half of endoporus dial (11) length.
In Fig. 7, Fig. 8, Fig. 9, password dial central axis (18) outer rim is provided with active pin shaft zigzag boss (17), and password dial central axis (18) is connected with active pin shaft (7) by axle head active pin shaft boss (14).When unblanking, needing to stir password dial (8) with hand earlier makes six password dials present the password of predefined six figure places, at this moment, groove on six endoporus dial centre bores (12) is on same branch line, then key (5) is inserted in the key core (6) and screw key (5), like this password dial central axis (18) just can be under the drive of key core (6) right motion vertically, thereby active pin shaft groove (16) aligns with locking bar groove (4), make active pin shaft (7) can not limit moving up and down of U-shape sword iron (1), promptly lock is opened.Have only when password input that lock just can be opened when correct and key was correct, strengthened the security performance of theftproof lock.Simultaneously, after theftproof lock is unlocked, password dial central axis (18) moves right, password dial this moment (8) also can move right and endoporus dial (11) outer rim on the tooth platform can not be meshed with the inner tooth platform of password dial (8), so just can be by changing the purpose of password dial (8) with endoporus dial (11) relative position realization replacing unlocking cipher.
