Abstract

The utility model discloses a lock for the confidential cubicles. A rotation disc, a fixed disk and each active lever of the lock, which have been machined from the blanks made by casting the copper material, are divided into two separated pieces respectively, thereby, a separation composite structure is formed, each of the separation pieces are processed respectively and are combined to form integral components. Because no copper material is used, the utility model has the advantages of simple preparing process, short production period, low cost and high intensity. Furthermore, a toggling proof slice is arranged additionally between a door wall and a spring, thereby, the confidential performance of a machine combination lock is enhanced.

Description

Seperatable-type mechnical cipher lock

The utility model belongs to a kind of lockset of safety cabinet.

The existing mechanical coded lock as shown in Figure 1, its critical piece rotating disc (1), fixed disk (2) and initiatively plectrum (3) be overall structure, after normally copper material is cast blank preferably by casting character, pass through machining again and make.This processing method not only will expend a large amount of non-ferrous metals, and its production cycle is long, the cost height, and intensity is low.

The utility model is in order to overcome above-mentioned shortcoming, provide a kind of can be without copper material, cost is low, mechanical code lock with short production cycle.

Main points of the present utility model are:

Rotating disc (1), fixed disk (2) and active plectrum (3) respectively are decomposed into two separation members to be made.Rotating disc (1) comprises Handle axis (4) and (5) two separation members of dial, and the shaft shoulder (7) and pillow block (6) are arranged on the Handle axis (4), and it is fixing that dial (5) is close to pillow block (6) back.Fixed disk (2) comprises fixedly card (8) and (9) two separation members of fixed disk axle sleeve, fixedly installing hole is left at the center of card (8), one end of fixed disk axle sleeve (9) is the shaft shoulder (10) and pillow block (11), and it is fixing that fixedly card (8) is close to pillow block (11) back.Initiatively plectrum (3) comprises plectrum (12) and (13) two separation members of drive sleeve, the centre bore of plectrum (12) has projection (14), on the axial end face of drive sleeve (13) fluted (15), plectrum (12) and drive sleeve (13) back of pegging graft is fixing.

Because the utility model adopted is the separate combination type structure, each separation member is processed the back respectively and formed integrated member, makes that its processing technology is simple, and is with short production cycle, and it is low to have a cost, saves a large amount of copper materials, and the intensity advantages of higher.

Fig. 2 is a rotary disk structure schematic diagram of the present utility model.

Fig. 3 is a fixed disk structural representation of the present utility model.

Fig. 4 is an active plectrum structural representation of the present utility model.

Fig. 5 is the structural representation after the utility model assembling.

Handle axis of the present utility model (4) is made through cutting by carbon steel, dial (5) is made with cold-rolling steel-plate punch, installing hole is left at the center, dial (5) is installed in the shaft shoulder (7) of Handle axis (4) and goes up and be close to pillow block (6), and dial (5) is to be fixed into as a whole member (1) with the method for riveting with Handle axis (4).Fixed disk card (8) is made with cold-rolling steel-plate punch, and fixed disk axle sleeve (9) is made with the carbon steel cutting.Plectrum (12) is made with the carbon steel sheet punching press, the small embossment (14) that has transmission to use at centre bore, drive sleeve (13) is made with carbon steel, and make the groove that matches with transmission projection on plectrum (12) centre bore at an axial end face, during installation the groove on the drive sleeve (13) aimed at the transmission projection on plectrum (12) centre bore, inlaying is an integral body, also can adopt the riveted joint or be welded.

Fig. 5 is the mechanical code lock that adopts separation member to form, and the rotating disc among the figure (1), fixed disk (2) and active plectrum are that separation member is assembled into.On the cabinet door that old-fashioned mechanical code lock is installed, close lock place can beat easily and spy upon aperture, utilizes mandrin and illuminations, can get a glimpse of and verify the groove of unblanking of several plectrums, will lock unlatching then, has reduced the safety performance of lock.The utility model has increased an anti-plectrum (18) between Men Bi (16) and spring (17), anti-plectrum (18) is the circular ring metal sheet, but punching press is made.The outside diameter of anti-plectrum (18) is slightly larger than the outside diameter of plectrum, and diameter of bore is advisable going up freely to rotate and move axially at fixed disk axle sleeve (9).So not only can prevent to spy on and directly verify the groove of unblanking, also can avoid on anti-plectrum (18), beating again and spy upon the hole, improve the security performance of mechanical code lock with probe.
