Abstract

The utility model relates to a slide-fastener cipher locking device without a padlock, which adopts the dial type cipher structure, and the lock core and the lock body of the cipher lock and one of two slide fastener heads are arranged together. The utility model is characterized in that the slide-fastener cipher locking device comprises two slide fastener heads whose open and close directions are opposite, pull sheets and the lock core and the lock body of the cipher lock, the front end of the slide fastener head which is not provided together with the lock body is provided with a lock hook which can be inserted into the lock body, and the lock tongue in the lock core structure of the cipher lock can be in the fastening or the loosening status. The utility model has the advantages of skillful locking mechanism design and convenient operation.

Description

Slide fastener cipher locking device

The utility model is about a kind of slide fastener locking device without padlock.

Existing band slide fastener case and bag will prevent that slide fastener from arbitrarily not opened, generally all need carry a padlock, by the slide fastener sheet with fix a place outstanding link to connect reach sealed purpose, but this additional one is neither attractive in appearance impracticable again the mode of padlock, the utility model notification number is that CN2044812U discloses a kind of " slider of zipper fastener " application case, its structure is the cipher lock core lock body that is provided with a dial-type cryptography architecture on slider of zipper fastener, when non-unlocking condition, the end of arrester hook is compressing zipper teeth in the lock core, slider of zipper fastener just can't slide, the shortcoming of this slide fastener locking device maximum is to damage zipper teeth easily, and its structure is also unreasonable.

The purpose of the utility model is that will to overcome above-mentioned existing in prior technology not enough and provide a kind of zipper slide but still the password locking device that can lock.

This device still adopts the dial-type cryptography architecture, this cipher lock core lock body is provided with slider of zipper fastener, be characterized in forming by the opposite slider of zipper fastener of two folding directions and pulling-on piece thereof and cipher lock core lock body, wherein the slider of zipper fastener front end that is not provided with lock body is provided with latch hook and can inserts in the lock body, is fastening or the two states that gets loose with dead bolt in the cipher lock core structure.

Above-mentioned the utility model whole device when the locking slide fastener all can slide on slide fastener and need not adopt the prevention slider of zipper fastener this original scheme of locking zipper to conceive, promptly do not damage the slide fastener teeth, use this device to provide bigger convenience simultaneously the folding of slide fastener.

Further illustrate the utility model below in conjunction with description of drawings, provide embodiment simultaneously.

Fig. 1 is the example structure side partial sectional view.

Fig. 2 opens the face partial sectional view for example structure.

Fig. 3 is Fig. 2 B B sectional view.

(1) pulling-on piece wherein, (2) slider of zipper fastener, (3) lock body base, (4) latch hook, (5) dead bolt, (6) digital wheel, (7) periphery cam, (8) axis, (9) lock body loam cake, (10) rotate top flat, (11) dead bolt top leaf of spring, (12) slider of zipper fastener, (13) axis spring, (14) become the sign indicating number push rod.

As shown in the figure, the dial-type cipher lock core structure that the utility model adopts is common in the general combination lock, when it scabbles face with parallel being adjacent to of dead bolt (5) when the periphery cam (7) that is meshed with digital wheel (6), corresponding digital wheel (6) numeral is exactly the unlocking cipher number, dead bolt (5) generally adopts the grid type shape and structure with digital wheel (6) and periphery cam (7) when combining, be beneficial to how secondary digital wheel (6) and periphery cam (7) mechanism and arrange setting, when changing or claim to rotate digital wheel (6), dead bolt (5) changes the present position under periphery cam (7) effect.Then be that dead bolt (5) clinching is to inserting lock body (3 in the present embodiment, 9) on the slider of zipper fastener in (2) the front end latch hook (4), stoped slider of zipper fastener (2) to withdraw from lock body (3,9), reach sealed purpose, the slider of zipper fastener (2 that both direction is opposite, 12) all be to be in slide fastener drawing state this moment, the A direction of arrow is the open chain direction among Fig. 1, in the present embodiment, slider of zipper fastener (12) is wholely set with lock body bottom (3), be slider of zipper fastener (12) and lock core lock body (3,9) be wholely set, slider of zipper fastener (12) and lock body (3 have been omitted, 9) bindiny mechanism is provided with, when present embodiment becomes sign indicating number at needs, only need to promote to become sign indicating number push rod (14), make the periphery cam (7) and digital wheel (6) axial separation that are enclosed within on the axis (8).Rotate digital wheel (6) and can set unlocking cipher number arbitrarily this moment, need to prove when periphery cam (7) is in unlocking condition with dead bolt (5) is non-, because reasons such as dead bolt (5) grid type shape and structure make a change sign indicating number push rod (14) can not promote periphery cam (7) and set digital wheel (6) coded number arbitrarily on axis (8) direction.

Claims

1, a kind of not with the slide fastener password locking device of padlock, adopt the dial-type cryptography architecture, this cipher lock core lock body is provided with a slider of zipper fastener, it is characterized in that forming with the cipher lock core lock body by two opposite slider of zipper fastener (2,12) and pulling-on pieces (1) thereof of folding direction, wherein slider of zipper fastener (2) front end that is not provided with lock body (3,9) is provided with latch hook (3) and can inserts in the lock body (9), is fastening or the two states that gets loose with dead bolt (5) in the cipher lock core structure.

2,, it is characterized in that coded lock lock body (3,9) and slider of zipper fastener (12) are wholely set according to the described slide fastener password of claim 1 locking device.
