A double contact switch is positioned at the external of the backpack body; two fixing contacts of the switch are respectively connected flexibly to two ends of a copper wire; the flexible is connected to the alarming ring and the power source and, after dividing into two connecting wire, is respectively connected to two ends of another copper wire; the two copper wires are arranged in parallel alongside the fastener; a conductor block that contacts and connects to the two cooper wire in sliding is positioned in between the two copper wires; the conductor block is connected solidly to the zip of the slide fastener.

Description

A kind of knapsack with Antitheft zipper

Technical field

The utility model relates to a kind of daily living article, specifically, is a kind of knapsack with Antitheft zipper.

Background technology

Along with being on the increase of people's daily living article, knapsack has become the indispensable daily life tools of people.Particularly for the women, knapsack has become their be used to dress up oneself fashion and has decorated.Thief's wildness now, and knapsack in the market is common zippered mostly, does not have anti-theft feature, uses to people and has brought a lot of inconvenience.So far also there is not a kind of good scheme to solve this type of problem.

Summary of the invention

The purpose of this utility model is in order to solve the deficiency of above-mentioned background technology, proposes a kind of simple in structurely, easy and simple to handle, with low cost, has the knapsack of a kind of novel band Antitheft zipper of anti-theft feature.

At above-mentioned purpose, a kind of knapsack that the utility model is designed with Antitheft zipper, it comprises knapsack body, slide fastener, copper wire, power supply, emergency alarm bell and switch, it is characterized in that: be installed with a double contact switch in the external side of knapsack, two fixed contacts of switch link to each other with the two ends of a copper wire respectively, connect separated time behind armature contact connection emergency alarm bell, the power supply and be divided into two, the two ends with another root copper wire link to each other respectively; Two copper wires are located at by the slide fastener abreast, and the two ends of copper wire are fixed on the knapsack body, and copper wire length is having one section insulating segment more than or equal to the length of slide fastener near the slide fastener shutdown side, outer wrap insulation rubber; Be provided with a conductor block that can remain in contact with one another with two copper wires and be slidingly connected with two copper wires between two copper wires, conductor block is fixedlyed connected with the zip of slide fastener.

Power supply and alarm are installed in the knapsack body.The two ends of conductor block have aperture, and copper wire and hole wall penetrate in the aperture in intimate contact, conductor block conducting two copper wires.Alarm can be common electric bell, also can be buzzer.

Principle of the present utility model is: conductor block and copper wire are equivalent to a slide switch by the cooperation of insulated part on mutual slip and the copper wire.By the break-make of the double contact switch in this slide switch and the circuit, the alarm equipment alarm in the control circuit.When double contact switch is connected copper wire away from the slide fastener shutdown side, unzip, then conductor block is connected circuit, alarm equipment alarm; When double contact switch is connected the copper wire of close slide fastener shutdown side, unzip, then because switch disconnects circuit, alarm is not reported to the police.

The utility model is simple in structure, easy and simple to handle, with low cost, and has anti-theft feature, is fit to very much people and uses in daily life.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail: in knapsack body 1 slide fastener 2 both sides, two copper wires 3 of parallel placement, 3 on two copper wires are provided with a conductor block 6, keep in touch also and can slide mutually with two copper wires 3, and copper wire 3 two ends are fixed on the knapsack body 1.In the left hand external of knapsack body 1, a fixedly connected inside is equipped with the switch enclosure of a double contact switch 4.Two fixed contacts 10 of double contact switch 4 link to each other with the left and right two ends of a copper wire 3 respectively, connect separated time behind armature contact 11 connection alarms 9, the power supply 8 and are divided into two, and the two ends with another root copper wire 3 link to each other respectively.Alarm 9 and power supply 8 are installed in the plastic casing, are fixed in the knapsack body 1.Connect used lead and joint all in knapsack body 1, be sealed in the interlayer of sewing up with empire cloth knapsack body 1 inboard.

Conductor block 6 two ends have aperture 12, two copper wires 3 and are through respectively in two apertures 12, and aperture 12 sizes keep closely contacting with copper wire 3, and can slide mutually than copper wire 3 slightly larger in diameter.Two metal clips also can be fixed in conductor block 6 two ends, clamp copper wire 3.Conductor block 6 is fixed on the zip 7 of slide fastener 2.

One section of closing apart from slide fastener 2 of copper wire 3 is provided with one section insulating segment 5, and the length of insulating segment 5 is slightly larger than the width of conductor block 6 and is advisable.The copper wire 3 of insulating segment 5, outer wrap one deck insulating cement.This insulating segment 5 is divided into two circuit, slidably reciprocates by conductor block 6 and controls the break-make of two circuit, the switch of a similar slip.When double contact switch 4 is connected copper wire 3 away from the slide fastener shutdown side, unzip 2, then conductor block 6 is connected circuit a, and alarm 9 is reported to the police; When double contact switch 4 is connected the copper wire 3 of close slide fastener 2 shutdown sides, unzip 2, then because switch disconnects circuit a, alarm 9 is not reported to the police; When double contact switch 4 is connected the copper wire 3 of close slide fastener 2 shutdown sides, close slide fastener 2, when slide fastener 2 was pulled through insulating segment 5, conductor block 6 had been connected circuit b, and alarm 9 is reported to the police, and reminds the user that double contact switch 4 is transferred to guard mode.Described alarm 9 uses common electric bell or buzzer.
