Description

Slide fastener does not fasten alarming device

Technical field

The utility model relates to a kind of slide fastener, and particularly a kind of slide fastener does not fasten alarming device.

Background technology

At present, " slide fastener " is to arrange by double coupler body is corresponding, and is combined with slider of zipper fastener, by slider of zipper fastener by the time can fasten two corresponding row's coupler body fastening or disengagings successively; Because its volume is lightly convenient, price is cheap, therefore is widely used in various articles for use in the daily life.

But, at present slide fastener in using main use shortcoming for people when slide fastener does not fasten fully can't know, the case that often causes using, bag in article drop out and do not know; And public security is low now, the pickpocket hardened thief is also often taken place draw back carry-on bag, wrap the thing that slide fastener is stolen property.

The utility model content

In view of this, main purpose of the present utility model is to provide a kind of slide fastener not fasten alarming device, makes can not send the alerting nunciator when slide fastener fastens in good time.

Content of the present utility model is to provide a kind of slide fastener not fasten alarming device, and this device comprises:

Detection switch has the two detecting bodies that can contact or separate, and its contact the time is open-circuit condition, then is closed circuit state during separation; It is connected with phonation circuit;

Phonation circuit is buzzer or loudspeaker and drive circuit thereof; It is series at described detection switch one end;

Power circuit, supplying DC power source is also connected with the described detection switch other end;

Two detecting bodies of described detection switch are located at the relative contact site of double slide fastener head of the slide fastener with double slide fastener head respectively; Or two detecting bodies of this detection switch are located at the slider of zipper fastener of the slide fastener with single slider of zipper fastener and the relative contact site of slide fastener installing place outside the slide fastener buckling end respectively.

By the realization of above technical scheme, can work as slide fastener and not fasten when locating, send the caution sodar to the caution effect, therefore the utlity model has good practical function.

Fig. 1 is that structure of the present utility model is formed calcspar;

Fig. 2 is first structure and the action schematic diagram of first embodiment of the present utility model;

Fig. 3 is the second action schematic diagram of the utility model first embodiment;

Fig. 4 is first structure and the action schematic diagram of the utility model second embodiment;

Fig. 5 is the second action schematic diagram of the utility model second embodiment.

The specific embodiment

See also Fig. 1, form calcspar for structure of the present utility model, it comprises:

Detection switch 1 has the two detecting bodies 10,11 that can contact or separate, and its contact the time is open-circuit condition, then is closed circuit state during separation; It should be connected with phonation circuit 2;

Phonation circuit 2 can be buzzer (buzzer) or loudspeaker (speaker) and drive circuit thereof; It should be connected with detection switch 1;

Power circuit 3, supplying DC power source, it should be connected with detection switch 1.

Like this, the utility model can be according to the otherness of zipper, and different application modes is arranged:

First embodiment

As shown in Figures 2 and 3, for the utility model is applied to have on the slide fastener 4 of double slide fastener head 40,41, wherein, two detecting bodies 10,11 of this detection switch 1 should be located at the relative contact site of this double slide fastener head 40,41 respectively; This phonation circuit 2 and power circuit 3 can be installed on the slider of zipper fastener 40 of one of them;

Like this, under two slider of zipper fasteners 40,41 and detecting body 10,11 mutual buckling states of slide fastener 4, it is an open-circuit condition; Please refer to Fig. 2;

And when two slider of zipper fasteners 40,41 of slide fastener 4 and detecting body 10,11 do not fasten, then be closed circuit state, phonation circuit 2 sends caution sound with power circuit 3 conductings and warns slide fastener not fasten to the location.

Second embodiment

As Fig. 4 and shown in Figure 5, be applied to for the utility model on the slide fastener 5 of single slider of zipper fastener 50, wherein, two of this detection switch 1 detecting bodies 10,11 are located at the relative contact site of slide fastener 5 installings place 51 (for example knapsack) outside this slider of zipper fastener 50 and slide fastener 5 buckling ends respectively; This phonation circuit 2 and power circuit 3 can be installed in this slider of zipper fastener 50;

Like this, under the slider of zipper fastener 50 and detecting body 10,11 mutual buckling states of slide fastener 5, it is an open-circuit condition; Please refer to Fig. 4;

And when the detecting body 10 of the slider of zipper fastener 50 of slide fastener 5 fastens with another detecting body 11, then be closed circuit state, phonation circuit 2 sends caution sound with power circuit 3 conductings and warns slide fastener not fasten to the location.

By above circuit application, can not fasten when locating at slide fastener, send the caution sodar to the caution effect.

The above is preferred embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model.
