Abstract

The utility model relates to a multiple group mechanical cipher device for safes. A lock core (1), a small number plate (2), and a big number plate (3) are orderly arranged in a lock body (4) from a centre line to the outside; multiple ball grooves are arranged at a position which penetrates the lock core (1), the small number plate (2), the big number plate (3), and the lock body (4); multiple balls are installed in each of the ball grooves. When two keys which are matched with each other are orderly inserted into the lock core (1), people can rotate the number plates and encode like unlocking. The utility model has high security of encoding, the codes can not be deciphered by hands directly dialing the number plates, the volume of the utility model is small, and the utility model can be conveniently used in miniature safes.

Description

Safety cabinet is organized mechanical coding device more

The utility model relates to a kind of many groups mechanical coding device of safety cabinet.

General safety cabinet code device only comprises a group coding.During the opening safety cabinet, rotate figure disc with hand and check the number, use key operated another built-in lock then, can open safety cabinet.The code device of this safety cabinet is owing to be directly to rotate figure disc with hand, thereby, even do not know password, also might be with the feel dial-up, confidentiality is poor.In addition, this kind safety cabinet has only a group coding, and a people grasps password can open safety cabinet.At the shortcoming of above-mentioned safety cabinet, people have designed many schemes, as electronic code device, and multiple encryption apparatus, these schemes have overcome the shortcoming of general safety cabinet to a certain extent, but all have the shortcoming of device complexity.This has not only reduced the functional reliability of device, and because device volume is bigger, inapplicable on small-sized safety cabinet.

The purpose of this utility model provides a kind of existing higher confidentiality, and is simple in structure again, many groups mechanical coding device of the safety cabinet that volume is little.

The technical solution of the utility model is: in lock body cylindraceous (4), by central axis lock core (1) outwards is installed successively, little figure disc (2) and big figure disc (3); Little figure disc (2) is made up of interior dial face (13) and interior cylinder afterbody (14); Big figure disc (3) is made up of EXT scale card (15) and outside cylinder afterbody (16); The interior cylinder afterbody (14) of little figure disc (2) places in the outside cylinder afterbody (16) of big figure disc (3), and lock core (1) places in the interior cylindrical rear portion (14) of little figure disc (2); Outside cylinder afterbody (16) end of big figure disc (3) is provided with one group of lesser calorie position dish, and little driving disc spacing pressing (7) and little clutch plate (6) are wherein arranged; Interior cylinder afterbody (14) end of little figure disc (2) is provided with one group big screens dish, and big driving disc spacing pressing (10) and big clutch plate (9) are wherein arranged; Running through lock core (1), the interior cylinder afterbody (14) of little figure disc (2), the outside cylinder afterbody (16) of big figure disc (3) and a side position of lock body (4) are provided with a plurality of ball races (5), are mounted with many hoodles in the different groove of each bullet.

Below in conjunction with embodiment structure of the present utility model is described, operating principle and beneficial effect.

Fig. 1 is the front view of the utility model embodiment;

Fig. 2 be among Fig. 1 A-A to sectional view.

As depicted in figs. 1 and 2, the outermost layer of whole code device is a lock body 4 cylindraceous, and it plays a protective role to whole code device.In lock body 4, by center line lock core 1 outwards is installed successively, small size code-disc 2 and big figure disc 3.Small size code-disc 2 is made up of interior dial face 13 and interior cylinder afterbody 14.Big figure disc 3 is made up of EXT scale card 15 and outside cylinder afterbody 16.In, be equipped with certain calibration on the EXT scale card.The interior cylinder afterbody 14 of small size code-disc 2 places in the outside cylinder afterbody 16 of big figure disc 3, and lock core 1 places in the interior cylindrical rear portion 14 of small size code-disc 2.Outside cylinder afterbody 16 ends of big figure disc 3 are provided with one group of lesser calorie position dish, and little driving disc spacing pressing 7 and little clutch plate 6 are wherein arranged, and are mounted with packing ring 8 between little driving disc spacing pressing 7 and the little clutch plate 6; Interior cylinder afterbody 14 ends of small size code-disc 2 are provided with one group big screens dish, and big driving disc spacing pressing 10 and big clutch plate 9 are wherein arranged, and are mounted with packing ring 11 between big driving disc spacing pressing 10 and the big clutch plate 9; Running through lock core 1, the interior cylinder afterbody 14 of small size code-disc 2, the outside cylinder afterbody 16 of big figure disc 3 and a side position of lock body 4 are provided with a plurality of ball races 5, are mounted with many hoodles (not drawing among the figure) in each ball race.

Open the code device that the utility model provides, need with two keys and two groups of passwords.When first key inserted lock core 1, key made hoodles in the ball race 5 along the alignment of the contact surface between outside cylinder afterbody 16 and the lock body 4, and this moment, key can drive big figure disc 3 and small size code-disc 2 rotates in lock body 4, carried out first group coding.Drive little clutch plate 6 by little driving disc spacing pressing 7 by sign indicating number pin 12 and rotate, make the sign indicating number mouthful alignment on little driving disc spacing pressing 7 and the little clutch plate 6, finish first group coding.Extract first key then out, and insert second key.Second key makes hoodles in the ball race 5 along the alignment of the contact surface between interior cylinder afterbody 14 and the outside cylinder afterbody 16, and key can drive small size code-disc 2 and rotated in outside cylinder afterbody 16 this moment, carried out second group coding.Rotate by the big clutch plate 9 of sign indicating number pin 12 drives by big driving disc spacing pressing 10, the sign indicating number mouth on big driving disc spacing pressing 10 and the big clutch plate 9 is alignd with the first group code mouth, finish second group coding.

In sum, safety cabinet provided by the utility model is organized mechanical coding device more, adopt two cover codings, and when opening, need use two keys, not only can not directly stir figure disc and come the sniffing attack coding, improve the confidentiality of coding by hand, and because the code device structure design that the utility model provides is simple and practical, reduced volume, thereby can in small-sized safety cabinet, use easily.In addition, hand over different personnel to grasp two keys, the generation of stealing in can also preventing.
