Abstract

The utility model relates to a lock which is applicable to the door, the safe and the car lock which comprises a button connecting axis and a steel ball which is pressed by the three function tooth pin in ninety degree angle; the three function tooth pin is moved downwards; the bayonet of the three function pin is meshed with the V shape bayonet pin to make the V shape bayonet move backwards to give position to the rotating axis and drive the lock to move transversely to unlock; the mechanical numeral lock has a simple structure, is convenient to be used and has a strong safety and secret keeping capability.

Description

Mechanical digital lock

The utility model is mainly used in various door locks, safety cabinet, lock etc.

At current market and the historical various locksets that stay, numerous, great majority always be unable to do without key, carry very inconvenience and open easily.Rotary in recent years coded lock is used for leather trunk and so on, but hatching line is aimed at trouble, is not easy to night open, and also has a kind of button digital phase-locking, and numeral is easily revealed, and numeral is single can't open up markets at all.

The purpose of this utility model is that a kind of high safety will be provided, and number is adjustable, open lockset easily.

The utility model is achieved in that this lock comprises lock body, button, the connecting axle that makes zero, open that turning cylinder, spring, protruding nail, connecting axle, three usefulness alligator sheet, ball, axle sleeve, seven shapes close the sheet gear piece, close the tooth spring, zero key sheet, V-type bayonet pin, bayonet socket spring, three usefulness alligator spring, dead bolt composition.The even distribution of above part is installed on the housing, 4 of its braces, ball extruding on the three usefulness alligator on 90 ° right angles and the housing, making it alligator moves downward, have a breach on the alligator, follow the V-type bayonet pin to contain and connect, make it the V-type bayonet pin and move backward, turning cylinder is just rotatable, has reached the effect of unlock deadbolt.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1: be structural representation of the present utility model.

Fig. 2: be side-looking structural representation of the present utility model.

Fig. 3: be the schematic diagram that seven shapes of the present utility model are closed gear piece.

Fig. 4: the schematic diagram that is zero key sheet of the present utility model.

Fig. 5: the schematic diagram that is connecting axle of the present utility model.

In the drawings: 1, lock body; 2, button; 3, the connecting axle that makes zero; 4, open turning cylinder; 5, spring; 6, protruding nail; 7, connecting axle; 8, three use alligator; 9, ball; 10, bayonet socket; 11, tooth mouth; 12, axle sleeve; 13, seven shapes are closed gear piece; 14, zero key sheet; 15, close the gear piece spring; 16, V-type bayonet pin; 17, bayonet socket spring; 18, alligator spring; 19, screw.

A kind of mechanical digital lock, it is harmonious the button (2) and connecting axle (3) connecting axle (7) that makes zero, is installed on the housing (1), cover upper spring (5), protruding nail (6) is installed in the medium position of housing.At first, button (2) is firmly depressed connecting axle (7), the ball (9) middle from 90 ° right angles and its three usefulness alligator (8) pushes mutually, make the diametrical position of the whole ball that descends of three usefulness alligator (8), actual is that tooth pitch, seven shapes are closed gear piece (13) under the effect of spring, blocks alligator (8) return, button (2) unclamps, connecting axle (7) playback, ball (9) falls one automatically, replenishes the origin-location, this lock has a bayonet socket (10) by 4 of three usefulness alligators are arranged on each alligator.If be harmonious with V-type bayonet socket (16), V-type bayonet socket (16) moves forward under the effect of spring, makes way for to open turning cylinder (4) rotation, drives the dead bolt transverse movement, reaches the purpose of unlatching, finishes whole action, and flicking is returned connecting axle (3), both can pin.

Press connecting axle (7), the extruding downwards of the ball (9) of connecting axle (7) in the middle of alligator (8), make alligator (8) move down a ball position, seven shapes are closed gear piece (13) and are blocked under bayonet socket spring (17) effect, control three usefulness alligator (8) upwards, ball falls one automatically, replenish the origin-location, through bayonet socket (10) above three usefulness alligator (8) is harmonious with V-type bayonet pin (16), V-type bayonet pin (16) moves backward to make way for and opens the purpose that turning cylinder (4) rotation reaches unlatching under the effect of bayonet socket spring (17).

Number is regulated and changed: this lock adopts four buttons, supposition now is called ABCD, wanting number is 2163: at first press on button A 2 times, press on the B key 1 time, C key 6 times, D key 3 times, then corresponding screw (19) be transferred to corresponding position and hatching line both can, equal like this with to the position of making zero, three usefulness alligator (8).The bayonet socket (10) on the right equals the A key with the position of V-type bayonet pin (16) distance to be pressed 2 times, and the B key is pressed 1 time, and the C key is pressed 6 times, the D key is pressed 3 times, finish current action both can, as press zero key E, seven shape gear pieces (13) withdraw under the control of zero key sheet (14) with V-type bayonet pin (16), make way for three usefulness alligator (8), three usefulness alligator (8) makes zero rapidly under the effect of spring, and while V-type bayonet pin (16) can not advance and bottle up, open turning cylinder (4), can not rotate.Reached like this be provided with that password is simple, insurance, effect that security performance is strong.

Claims

1, mechanical digital lock, it is characterized in that comprising lock body (1), button (2), the connecting axle that makes zero (3), open turning cylinder (4), spring (5), protruding nail (6), connecting axle (7), three usefulness alligator (8), ball (9), bayonet socket (10), tooth mouth (11), axle sleeve (12), seven shapes close gear piece (13), zero key sheet (14), close gear piece spring (15), V-type bayonet pin (16), tooth card spring (17), alligator spring compositions such as (18), fit over mutually on the lock body (1).

2, mechanical digital lock according to claim 1, it is characterized in that ball (9) extruding of connecting axle (7) from 90 ° right angle and its three usefulness alligator (8) centre, make the position (actual is tooth pitch) of the whole ball diameter that descends of three usefulness alligator (8), seven shapes are closed gear piece (13) and are blocked closing under gear piece spring (15) effect, control three usefulness alligator (8) upwards, ball (9) falls automatically, replenish the origin-location, through bayonet socket (10) to three usefulness alligator (8) is harmonious with V-type bayonet pin (16), V-type bayonet pin (16) moves under the effect of bayonet socket spring (17) backward, makes way for to open turning cylinder (4) rotation process.
