Abstract

This utility model relates to a mechanism cipher lock comprising a lock body and a key cylinder. The lock body comprises a shield, a gear plate, cipher discs, a coupled screw rod and a lock pin. An active gear plate and a slave gear plate are added behind the common keyhole of the key cylinder, make the two axles be the main part, and a matched shield is set on the lock body, the shield is fixed on the board near the door, the cipher discs set many puzzle mouth, the coupled screw rod is set between the cipher discs. Every part couple to each other and it has the functions of preventing drilling, prying and opening by technique. This utility model has the simple structure, and it is small and safe.

Description

Antitheft mechanical code lock

Technical field

The utility model relates to a kind of antitheft mechanical code lock.

Background technology

At present, existing antitheft mechanical code lock all is to be made of password disk, lock pin, disk interlock screw rod, and its defective is that at first, the location is the tradition location, and ecto-entad locating detent mouth is not easy antitheft, anti-drilling; Secondly, password disk on this coded lock and rotational password screw rod easily find lock pin position, the inside on a main shaft, finally cause password cracking, easy stolen shortcoming.

Summary of the invention

Its purpose of the utility model just be to provide a kind of can anti-theft antitheft anti-drilling, multiple functional, simple to operate, cost of manufacture is low, the antitheft mechanical code lock that is difficult for cracking.

The technical solution of the utility model is: this antitheft mechanical code lock is made of lock body part and lock core, wherein lock body is made up of protective cover, toothed disc, password disk, interlock screw rod and lock pin, behind general lock core keyhole, add driving tooth wheel disc and driven tooth wheel disc, and be main body by two axles, and be provided with the protective cover of coupling at lock body part, protective cover is fixed on the panel that leans on door, and the password disk is provided with a plurality of fascinations mouths, is provided with the interlock screw rod between the password disk.

Advantage of the present utility model is 1) owing on each password disk, be provided with a plurality of fascinations mouths, make it can not find lock pin mouth on the disk, increase its theftproof; 2) owing to set up driving and driven toothed disc, thereby change tradition location program from outside to inside, and the utility model is a locating detent mouth from inside to outside, has the anti-drilling characteristics that add that electronic eyes is surveyed at lock body part; 3) owing to set up protective cover, have characteristics anti-drilling and that electronic eyes is surveyed; 4), have the characteristics of safety and confidentiality by key control cipher switch.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described,

Fig. 1 is the utility model structural representation;

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

The specific embodiment

As depicted in figs. 1 and 2, a kind of cipher code mechanical theftproof lock, constitute by lock body part and lock core, wherein lock body is made up of protective cover 1, driving tooth wheel disc 2, driven tooth wheel disc 3, password disk 4, interlock screw rod 5 and lock pin 6, before general lock core keyhole, add driving tooth wheel disc 2 and driven tooth wheel disc 3, and be main body by two axles 8, and be provided with the protective cover 1 of coupling at lock body part, protective cover 1 is fixed on the panel that leans on door, password disk 4 is provided with a plurality of fascinations mouths 7, and protective cover is inboard can not to surpass 2MM with gear interface is the wideest.

Operating principle: drive the driving tooth wheel disc with key, the driving tooth wheel disc promptly can drive the driven tooth wheel disc, drive outermost password disk by the interlock screw rod on the driven tooth wheel disc, taking second place then, by that analogy, is the password disk of innermost layer at last, the password disk that is the innermost layer is located earlier, after password combination was errorless, lock pin just can enter the lock pin mouth in the password disk, and lock is opened.

Claims

1, a kind of mechanical code anti-theft lock, constitute by lock body part and lock core, it is characterized in that: wherein lock body is made up of protective cover (1), driving tooth wheel disc (2), driven tooth wheel disc (3), password disk (4), interlock screw rod (5) and lock pin (6), before general lock core keyhole, add driving tooth wheel disc (2) and driven tooth wheel disc (3), and be main body by two axles (8), and be provided with the protective cover (1) of coupling at lock body part, protective cover (1) is fixed on the panel that leans on door, and password disk (4) is provided with a plurality of fascinations mouthful (7).

2, a kind of mechanical code anti-theft lock according to claim 1 is characterized in that: described protective cover is inboard can not to surpass 2MM with gear interface is the wideest.
