The mechanical cipher lock comprises a lock core, a lock core body, a marble and a spring which are arranged in the lock core and the lock core body, a protective jacket and a cutting wood which is fixed at the end of the lock core. The outer side of the lock core and the lock core body is provided respectively with cipher disks, each cipher disk is provided with a connector pin and a pulling pin, and the inner part of the lock core body is provided with a convex-shaped cipher pin which is corresponding to a pin groove. The spring is sheathed at the convex step surface point of the convex-shaped cipher pin, and the outermost cipher disk is connected tightly with a dial through the meshing engagement of hocks. When the utility model is used, the mechanical cipher lock needs the cipher and also needs a key, and has the advantages of dual effects, simple structure and convenient operation.

Description

Mechanical puzzle lock

The utility model belongs to the coded lock technology field, is a kind of mechanical cipher tapered end.

Present coded lock mostly is to adopt password unlocking, and does not need key, and the people that a kind of password uses of a specified duration and often knows is just many, has lost the password effect, and changes often difficulty and complicated relatively of password.The lock that does not have password, because of with key operated, key usually can be imitated and lose effect by the people.

The purpose of this utility model is a comprehensive coded lock and with the characteristics of key operated lock, not only need use when a kind of the unlatching is provided password, but also need be with the mechanical cipher tapered end of key.

The purpose of this utility model is to realize with the following methods.This mechanical cipher tapered end; comprise pellet shot from a slingshot and spring, protective sleeve in lock core, lock core body, lock core and the lock core body, be fixed on the cutting of lock core end; lock core and lock core body have combination disk outward; a cotter way and finger are arranged on each combination disk; in lock core body, there is the convex code pins corresponding with cotter way; the boss terrace place of spring housing in the convex code pins arranged, and outermost combination disk and dial are fastenedly connected by the hock engagement.The utility model will be further described below in conjunction with the embodiment accompanying drawing.

Fig. 1 the utility model structure sectional view;

Fig. 2 is the A-A view of Fig. 1;

Fig. 3 is the front view of combination disk (2);

Fig. 4 is the left side view of Fig. 3.

Among the figure, 1,2, the 3-combination disk, the 4-dial, the 5-lock core body, the 6-finger, the 7-code pins, the 8-lock core, the 9-protective sleeve, the 10-packing ring, 11-transplants a cutting, 12-key, 13-pellet shot from a slingshot, 14-cotter way, 15, the 16-spring, 17-finger jack, 18-pellet shot from a slingshot.

Dial has number on (4), be convenient to dial password, combination disk (1,2,3) has three, combination disk (1) goes up on two sides that have on the one side relative with combination disk (2) on a finger (6), the combination disk (2) respectively a finger (6), and combination disk (3) goes up on the one side relative with combination disk (2) a finger (6).Eight finger jacks (17) are arranged on each combination disk obverse, each finger jack (17) is different with respect to the position of the cotter way on each combination disk (14), finger (6) can insert any one in these eight finger jacks (17), owing to there be four corresponding to be that combination disk (1) has a face, combination disk (2) has two faces, combination disk (3) has a face, and the finger jack on each face all is on same circumference.On (3) two dishes of dial (4) and combination disk phase-contact surface 12 engagement hocks (figure does not draw) are arranged respectively.Because there is fixing numeral in the dial front as the Arabic numerals from 0-60,12 hocks on the dial back side contact with contacted 12 hocks of combination disk (3) and just can change 12 positions like this, can draw 12 numbers, and the finger of combination disk (6) has eight finger jack positions to select on each face, corresponding to the positive position digital and cotter way (14) of dial eight change locations are just arranged, because having has finger (6) on four faces, totally 8 * 8 * 8 * 8 * 12 change number like this, can have nearly 60,000 password layouts to select for the user.The key operated mechanism that also has pellet shot from a slingshot (18) and spring (15) to form in lock core (8) and the lock core body (5).

During use,, fix on the finger jack (17) as long as finger (6) fixed-site on three combination disk (1,2,3) is good, dialling good dish (4) reserves with the hock position of engagement of combination disk (3), and both are screwed, like this, it is good that the password of lock is just determined.If will change the coded lock numeral, as long as change on three combination disk the hock position of engagement of the position of any the place finger jack in 4 fingers or dial (4) and combination disk (3), the utility model mated with the lock body that has dead bolt both can again.When needs are opened tapered end, suppose that password is 20,35,28, then as long as by the method for opening general insurance mechanical code lock cashier's office in a shop, rotary dialer (4), to behind the good password, at this moment, three cotter ways (14) on three combination disk (1,2,3) are all over against three code pins (7), again with in the keyhole of key (12) insertion lock core (8) (situation as shown in Figure 1), under the effect of key, code pins is compressed spring (16) and is entered cotter way (14), key, band twist lock core is opened lock by transplanting a cutting.As can be seen from Figure 1, if password is not to (as long as have one not to), then code pins (7) does not align with cotter way (14), and code pins (7) just can not be under the effect of key, compress spring (16) and enter cotter way (14), and key can't insert at all.If password is right, key is wrong, and after key was entered, key can not rotate, and also just can't drive lock core and rotate.

The utility model is simple in structure, safe and secret, good reliability, easy to use, has two states available during use, and a kind of is without cryptographic function, with the first sample of common lock; The 2nd, when needs access to your password function,, get final product more than one week with the moving figure disc of hand-screw as long as after transfering to key, must revolve unlatching number to lock when unblanking next time, lock could be opened, and plays the effect of coded lock.All need install the place of door lock to be applicable to storehouse, family, security door etc.
