Description

Antitheft zipper

Technical field

The utility model relates to a kind of slide fastener, particularly has the slide fastener of anti-theft feature.

Background technology

Slide fastener is made up of drawstring and slider of zipper fastener, and drawstring comprises and draws tooth and granny rag, draws tooth to be generally a kind of material, or plastics, or irony, copper etc., and slider of zipper fastener comprises handle and pulling seat, and handle is through the draw ring on it and lock ring on the pulling seat and pulling seat flexible connection.Since slide fastener folding with convenience, quick, in many places application is arranged all, like clothing, bag class etc.But what all has dual character, and slide fastener has also given the thief with chance when being convenient for people to.Although people enhance your vigilance, the thief also can open slide fastener at very short time lira, and the thing in pocket or the case and bag is stolen, owing on the slide fastener warning device is not installed, people do not know completely when stolen property, are difficult in time perceive.

Summary of the invention

The purpose of the utility model provides a kind of slide fastener with anti-theft feature.

The described Antitheft zipper of the utility model comprises the slide fastener body of being made up of slider of zipper fastener and drawstring, and the handle and the pulling seat of slider of zipper fastener are insulator.The tooth that draws of drawstring constitutes by two sections, and the tooth that draws of latter end is an insulated part, and remaining draws tooth is current-carrying part.On pulling seat, be provided with two conductive poles, conductive pole with draw toe joint to touch.Handle is provided with warning device, and warning device is made up of power supply, buzzer, and power supply and buzzer draw tooth to form the closed-loop path through conductive pole, conduction.

Said slider of zipper fastener is provided with the switching device shifter with conductive pole and dump or conducting.

Said switching device shifter both can be the electric switch that is connected on the warning circuit, also can be the insulated column of insulation.If insulated column; Then insulated column is positioned at and is used on the pulling seat and the lock ring of shaking hands to be connected; Lock ring is divided into two cavitys; Handle can get into another cavity by a cavity, is provided with two conducting strips that are electrically connected with conductive pole in one of them cavity, and power supply and buzzer draw tooth to form the closed-loop path through conducting strip, conductive pole, conduction.

The utility model is because slide fastener is provided with warning device, and when the slide fastener drawing put in place, slider of zipper fastener was positioned at the insulated part of drawstring; And when the thief unziped, pulling seat got into current-carrying part by insulated part in the process of drawing back, and warning device forms the loop by breaking off; Buzzer sends the sound, and taking and carring away is eliminated in the preproduction phase, when drawing back the thief with fear; Owner can in time be discovered, can avoid property impaired.And owner oneself is when zipping; Can warning circuit be switched to non-alarm condition through switching device shifter (pressing change-over switch maybe will shake hands to switch to non-conductive cavity by the conduction cavity); Even pulling seat gets into current-carrying part, warning circuit also breaks off, and buzzer can not send the sound.After oneself using the slide fastener drawing to put in place, through switching device shifter warning circuit is switched to alarm condition again, promptly open warning function.

The slide fastener of the utility model can be widely used on various case and bag and the clothing, even these bag classes and clothing are not at one's side, because buzzer sends the sound, in certain distance range that sound can arrive, has warning function equally.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1 is the structural representation of the utility model.

Fig. 2 is the circuit diagram of the utility model.

Fig. 3 is a kind of structural representation of slider of zipper fastener.

The specific embodiment

Referring to Fig. 1, this Antitheft zipper comprises the slide fastener body of being made up of slider of zipper fastener 1 and drawstring 2, and the handle 3 and the pulling seat 4 of slider of zipper fastener 1 are insulator, also can be the isolated insulation body.The tooth 5 that draws of drawstring 2 constitutes by two sections, and the tooth 5 (referring to that part that the slide fastener drawing puts in place) that draws of latter end is an insulated part, and remaining draws tooth is current-carrying part, and the ratio of insulated part and current-carrying part is generally between 1: 4 to 1: 8.Be provided with two conductive poles 6 in pulling seat 4 rear ends, conductive pole 6 contacts with drawing tooth 5, and what conductive pole 6 and insulation drew that tooth and conduction draw tooth combines to be equivalent to the K switch 1 among Fig. 2, and conductive pole 6 is a round end with an end that draws tooth 5 to contact.Handle 3 is provided with warning device 7, and warning device 7 is made up of power supply and buzzer, and power supply and buzzer draw tooth 5 formation closed-loop paths through conductive pole 6, conduction.When pulling seat 4 was in the current-carrying part that draws tooth 5, whole warning circuit was conducting, and buzzer will send alarm sound; And when pulling seat 4 was in the insulated part that draws tooth 5, whole warning circuit broke off, and buzzer can not send alarm sound, and its circuit structure is referring to Fig. 2.Certainly, conductive pole also can be other forms of conductive structure, like conducting strip etc., also is not limited to and is located at the pulling seat rear end, can be located at the pulling seat bottom.

The embarrassment that when oneself zips, also can report to the police, present embodiment is provided with switching device shifter on slider of zipper fastener, be used for conductive pole 6 and dump or conducting.A kind of embodiment of switching device shifter is common electric switch K2, and K switch 2 is connected on the warning circuit, and between power supply and buzzer, its circuit is seen Fig. 2.When needs unzip, K switch 2 is broken off, therefore whole warning circuit is cut off, and buzzer can not distributed out alarm sound arbituarily.After the slide fastener drawing puts in place, again K switch 2 to be connected, this moment, warning device was in alarm condition again.

The another kind of embodiment of switching device shifter is the insulated column 9 of insulation, forms antitheft gear and safe gear through insulated column 9.Insulated column 9 is processed by elastomeric material, is positioned to be used for the lock ring 10 that is connected with handle 3 on the pulling seat 4, and lock ring 10 is divided into two cavitys 11 up and down, referring to Fig. 3, shakes hands 3 can when oneself draws, get into another cavity easily by a cavity.Be provided with two conducting strips 12 that are electrically connected with conductive pole 6 in a cavity below, this cavity is the antitheft gear, and another does not have the cavity of conducting strip to be safe gear.Handle 3 gets into when having the cavity of conducting strip 12, and power supply and buzzer draw tooth 5 formation loops through conducting strip 12, conductive pole 6, conduction.For make own between two gears easy switching, and others is awkward, present embodiment is provided with draw-in groove 13 below the cavity that has conducting strip 12 11, the draw ring 8 of handle 3 is stuck in the draw-in groove 13, through draw-in groove 13 will shake hands 3 with pulling seat 4 flexible connections.

When oneself need unzip, will shake hands earlier 3 in draw-in groove 13, to mention, will shake hands again 3 from the antitheft gear switch to the safety gear, this moment, therefore whole warning circuit was cut off, buzzer can not distributed out alarm sound arbituarily.Put in place when needing antitheft in the slide fastener drawing, will shake hands again 3 from the safety gear switch to the antitheft gear, be stuck in draw-in groove 13 interior getting final product to draw ring 8 at last.Like this, handle 3 just can oneself not gone here and there moving between two gears.Certainly, two cavitys about insulated column also can be divided into lock ring, perhaps insulated column is vertical with drawstring, and lock ring is divided into former and later two cavitys.
