Abstract

The utility model relates to an anti-theft cipher lock, which belongs to the improvement of a cylinder door lock. On the basis of an original cylinder door lock, a cipher lock is additionally arranged on the utility model. The cipher lock is composed of a cipher core axle (5), a limit safety ring (3) arranged on the cipher core axle (5), a cipher wheel (2), a limit sheet (4), etc. A bolt plate (12) is provided with a cipher lock hole (13) corresponding to the cipher core axle (5). Because the utility model adopts the cipher lock, the trouble that people always carry keys at the time of going out after locking the door is solved, and defects that the keys are easily forgotten to carry and are not easy to keep are overcome. At the time of the use of the utility model, adjusting the sequence number of each cipher is just needed, and people can go out with worry after pushing the cipher core axle and disordering the ciphers; when the people go back, the door can be opened by aligning the cipher number on the cipher wheel, pulling the cipher core axle, and rotating the cipher handwheel. If the people go far, the anti-theft cipher lock can play the double safety action; the use is convenient, and the safety can be ensured.

Description

Anti-theft cipher lock

The utility model relates to the improvement of pin tumbler lock.

The existing pin tumbler lock that uses all is to adopt the key insurance, gos out and must must carry key after locking a door, and causes to carry inconvenience and forget easily or lose the key phenomenon, brings great inconvenience to the user.

In view of the deficiencies in the prior art, the purpose of this utility model aims to provide the cipher anti theft door lock of going out in a kind of short time and can go away and can play the dual fail-safe effect not with door key, for a long time.

The utility model is realized as follows: the utility model comprises lock body (7), locking closure (9), dead bolt (11), bolt plate (12), lock core (8), internal lock handwheel (10), back-moving spring (14), coded lock (1) etc., described coded lock (1) is by password mandrel (5) and be located at spacing relieving ring (3) on the password mandrel (5), cipher wheel (2), banking stop (4), password rotor plate (6) etc. and form, and is provided with on bolt plate (12) and the corresponding cipher lock hole (13) of password mandrel (5).

The utility model is compared with prior art: compact conformation, rationally, easy to use, safety performance is strong.

The utility model has following accompanying drawing

Fig. 1 is a vertical profile schematic diagram of the present utility model

Fig. 2 is an A-A cut-away view of the present utility model

Fig. 3 is plan structure figure of the present utility model

Fig. 4 is the structure chart of password mandrel in the utility model

Fig. 5 is the B-B cut-away view of Fig. 4

Fig. 6 is the assembling schematic diagram of cipher wheel and password mandrel in the utility model

Accompanying drawing has been represented structure of the present utility model, in conjunction with the embodiments structure of the present utility model and use principle thereof is described in further detail below again.The utility model comprises lock body (7), locking closure (9), dead bolt (11), bolt plate (12), lock core (8), internal lock handwheel (10), back-moving spring (14), coded lock (1) etc., described coded lock (1) is reached the spacing relieving ring (3) that is used with it by password mandrel (5), cipher wheel (2), banking stop (4), password rotor plate compositions such as (6), on bolt plate (12), be provided with and the corresponding cipher lock hole (13) of password mandrel (5), cipher wheel (2) is three, respectively be provided with ten digital grooves on it, be respectively 0-9, and cooperate assembling with cylindrical projection that password is regulated rotor (15), when three cipher wheel go to password figure respectively, then the projection of three password adjusting rotors becomes on the same straight line, advance password mandrel (5) to enter cipher lock hole (13), pinning dead bolt can not withdraw from, then door is not opened, dial random code number, three passwords are regulated the projection of rotor not on same straight line, the password mandrel then can not pull, play safety effect, open the door into as long as aim at password figure, pull out password mandrel rotation password handwheel, can open the door.Adopt the utility model, under the situation of promptly returning soon of going out, the complete unnecessary key that carries, the lock that only need access to your password gets final product, Shi Zeke uses key lock and coded lock simultaneously if go away, and plays the dual fail-safe effect, and the password figure on the cipher wheel can be according to user's the free adjustment that requires, or change password figure for regent one time after using a period of time, it is easy and simple to handle, easy.

Coded lock structure of the present utility model and general strongbox coded lock are different, gap between each cipher wheel of general strongbox coded lock is big, can send noon sound during use, can have an opportunity to open through exploration with feel, ear sense, order sense, and coded lock structure of the present utility model is special, can not send the sound during use, and each password figure of misalignment is not opened not easily, it is safe and reliable convenient again using, and is suitable for each megahotel or family and uses.

Claims (2)

1, a kind of cipher anti theft door lock, comprise lock body (7), locking closure (9), dead bolt (11), bolt plate (12), lock core (8), internal lock handwheel (10), back-moving spring (14) etc., it is characterized in that: on above-mentioned door lock, set up coded lock (1), described coded lock (1) is made up of password mandrel (5) and the spacing relieving ring (3), cipher wheel (2), banking stop (4), the password rotor plate (6) that are located on the password mandrel (5), is provided with on bolt plate (12) and the corresponding cipher lock hole (13) of password mandrel (5).
