Abstract

The utility model relates to a digital theft-prevention lock. A group of rotatable digital rings with digits are arranged on a lock body; inner tooth rings are inlaid in the digital rings; a notch is arranged on each of the inner tooth rings; a rotating shaft with a shifting head is positioned in an inner sleeve pipe; a group of fixing pins corresponding to the inner tooth rings are arranged on the inner sleeve pipe, and are matched with the notches on the inner tooth rings one to one by grooves on an outer sleeve pipe; the rotating shaft extends into a positioning groove of the rotating shaft for positioning from the outer sleeve pipe and the inner sleeve pipe; a reset spring is sheathed on the inner sleeve pipe. The utility model undoes the lock by rotating corresponding setting digitals, and overcomes worries caused by that a key is lost and the lock can not undone. The utility model has the advantages of firm structure, theft prevention, and prying prevention, is a novel theft prevention lock, and can be used for the theft prevention of house doors, vehicles, etc.

Description

The digital anti-theft lock

The utility model belongs to commodity, is specifically related to a kind of structure of digital anti-theft lock.

Lock on the market mostly has key, the door of bicycle, motorcycle family lock all need key operated, often can't open because of key loss, and key operated lock mutual opening rate height, anti-theft effect is poor.

The purpose of this utility model is: design a kind of digital anti-theft lock, save the key of easily losing, anti-theft pick-proof is given away secrets and can be changed as password.

The technical solution of the utility model is: the rotatable digital circle that one group of band numeral is arranged on the lock body, digital circle is embedded with ring gear, one breach is arranged on the ring gear, the rotating shaft of band shifting block is enclosed within the inner sleeve, and one group of steady pin corresponding with gear ring is arranged on the inner sleeve, and the groove from outer tube stretches out, cooperate one by one with the breach on the ring gear, locating slot is arranged in the rotating shaft, and alignment pin stretches into the rotating shaft location from outer tube, and back-moving spring is enclosed within on the inner sleeve.

When rotating each digital circle, ring gear rotates synchronously, when the breach of whole ring gears was corresponding with one group of steady pin on the inner sleeve, rotating shaft, the steady pin just axial groove from the outer tube slipped into radial slot, under spring action, the shifting block that rotating shaft is ejected on it contacts with lock core, and rotating shaft can be opened lock, if the arbitrary breach on the digital circle is not corresponding with steady pin, lock is not just opened, and very strong theftproof is arranged.

Provide accompanying drawing of the present utility model below:

Fig. 1 is a structure sectional view of the present utility model

Fig. 2 is the utility model inner sleeve schematic diagram

Fig. 3 is the utility model outer tube schematic diagram

Among the figure: 1 lock body, 2 digital circles, 3 ring gears, 4 steady pins, 5 rotating shafts, 6 splicing sleeves, 7 back-moving springs, 8 alignment pins, 9 inner sleeves, 10 outer tubes, 11 rotating shaft knobs, 12 hold-down screws, 13 bodies, 14 rotating shaft shifting blocks, 15 door locks are opened square hole

Introduce embodiment of the present utility model below in conjunction with accompanying drawing:

The number circle 2 that one group of band 0-9 numeral is arranged on the lock body 1, digital circle 2 ring gears 3 that are embedded with a breach, ring gear 3 is enclosed within on the outer tube 10, have the axial groove and the radial slot that match with steady pin 4 on the outer tube 10, inner sleeve 9 is positioned at outer tube 10, one group of steady pin 4 is arranged on it, it cooperates with outer tube 10 and cooperates with ring gear 3 through the radial slot of outer tube 10, the rotating shaft 5 of band rotating shaft shifting block 14 is positioned at inner sleeve, there is a rotating shaft shifting block 14 at its rear portion, it is opened square hole 15 with door lock and matches, alignment pin 8 is through outer tube 10, inner sleeve 9 is located with the locating slot in the rotating shaft 5, back-moving spring 7 is between inner sleeve 9 and outer tube 10, hold-down screw 12 is fixing with door body 13 with lock body 1, and splicing sleeve 6 is positioned at the lock body most external to be had for the strip window of stirring digital circle 2 on it.

Number circle 2 on the rotational lock 1, embedding is that the ring gear 3 of one rotates thereupon with it, when putting in place by the password of setting, breach on the ring gear 3 and steady pin 4 are in same position, when the breach on whole digital circles 2 all is positioned at same position with steady pin, knob 11 on the rotating shaft 5, steady pin 4 slides to cannelure from the axial groove of outer tube, under the effect of back-moving spring 7, rotating shaft 5 is ejected, and rotating shaft is pulled out 14 and entered door lock and open square hole 15, rotation knob 11, rotating shaft is pulled out 14 for a square hole 15 that drive on the door lock and is rotated, and drives opening mechanism with door-lock opening.

The utility model is unblanked with predefined numeral, does not need key, has overcome the worry that can't open lock because of key loss, and lock body structure has tamper-resistant function, can own recompile after number is given away secrets, and be a kind of novel anti-theft digital lock.

Claims
