Abstract

The utility model relates to an anchor line for anchoring and binding goods and fence in a theft-proof device, which is designed for solving the problems that the existing anchor line can not transmit signal and can not be used for theft-proof systems. The utility model is a rope essentially, a conducting wire is twisted in the rope and is composed of a core post, an electric conducting wire and an insolating sheathing; the electric conducting wire is spirally wound on the core post, and the sheathing is coated on the core post and the electric conducting wire. The utility model can make the anchor line efficiently transmit the signal without affecting the performance of the anchor line, and the transmitting conducting wire has large extensibility, is not easy to break and can prevent bridging.

Description

A kind of hawser that is used for anti-theft device

The utility model belongs to a kind of anti-theft device that is used for and pulls and tie up the hawser that goods and fence are used.

It is constituted existing hawser or cable net single cable or is woven the stranding net by single rope by rope, because rope is made by palm fibre, fiber crops and artificial fibre etc., it is wear-resisting, folding, ageing-resistantly, corrosion-resistant, anti-draw, pliability is good, it is suitable for pulling ties up the goods on the car and boat or is used for fence.But, easily cause goods stolen because this rope is easy to be cut off.For general cable anti-theft alarm device, its lead is used for the anti-theft signal transmission, but owing to thicker lead, is not easy for pulling and ties up goods, and easily puts up a bridge; Thinner lead, its conductive filament is easily broken or is fractureed.

The purpose of this utility model is to address the above problem, and provides a kind of hawser that makes can transmit signal, does not influence the performance of hawser, and transfer wire is difficult for breaking, and can prevent the hawser that is used for anti-theft device of putting up a bridge.

It is made of the utility model rope, and twisting has lead in rope, and lead is made of stem stem, conductive filament and insulation exoperidium, and conductive filament is wrapped on the stem stem in a spiral manner, and exoperidium is wrapped on stem stem and the conductive filament.

The utility model can make hawser transmit signal effectively, does not influence the performance of hawser, and transfer wire has bigger stretching property, is difficult for being broken, and can prevent putting up a bridge, and can prevent to steal after anti-theft device uses.

Fig. 1 is the utility model structural representation;

Fig. 2 is for being provided with the structural representation of filamental thread in the utility model stem stem;

Fig. 3 is the structural representation of the utility model cable net;

Fig. 4 is the utility model warning circuit structural representation.

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

As shown in Figure 1, it is made of the utility model rope 1, and twisting has lead in rope 1, and lead is made of stem stem 2, conductive filament 3 and insulation exoperidium 4, and conductive filament 3 is wrapped on the stem stem 2 in a spiral manner, and exoperidium 4 is wrapped on stem stem 2 and the conductive filament 3.After feeding signal to lead, cut off hawser, lead disconnects, and signal feedback in anti-theft device, is produced alarm indication by the alarm in the anti-theft device.Rope is still made by materials such as palm fibre, fiber crops, artificial fibres.Stem stem and exoperidium have the material of certain toughness to constitute by rubber etc. is flexible, and stem stem is identical with the material of exoperidium.The spiral of conductive filament twines form, and conductive filament can be extended with rope, is difficult for being broken, and makes conductive filament can adopt very thin lead, prevents to put up a bridge.Lead enrolls when rope is pooled capital.

As shown in Figure 1, be positioned at the central authorities of rope with the lead of rope 1 twisting, promptly lead does not expose rope.When enrolling, be axle, rope is wrapped on the lead with the lead.

As shown in Figure 1, conductive filament 3 is an enamel-covered wire, and diameter is 0.05～0.1mm.Enamel-covered wire and exoperidium form compound insulation.Because enamel-covered wire is very thin, be difficult to the outer lacquer of enamel-covered wire be scraped off and enamel-covered wire is continuous, and compound insulation with hand, when the stripping exoperidium, also be easy to the enamel-covered wire stripping disconnectedly, can prevent to put up a bridge and steal.The dipping lacquer of enamel-covered wire with not embrittlement of low temperature, be difficult for wiping off, do not come off, the material of folding is advisable.

As shown in Figure 1, the helical angle of conductive filament is advisable with 65～80 °.

As shown in Figure 2, stem stem 2 is made by rubber, is provided with filamental thread 5 in the stem stem 2, the elasticity effect when twining conductive filament to reduce.The intensity of filamental thread is can break in the work, and the draftability that does not influence lead is advisable.

As shown in Figure 3, the rope 6 of twisting lead is woven into netted.

As shown in Figure 4, when the utility model hawser 7 is connected into the closed-loop path, and be energized by the power, supply voltage is a safe voltage, is serially connected with relay J and display lamp D in the loop, relay normally-closed contact J1 be serially connected on the loudspeaker L of alarm indication, when K switch 2 is closed, the K1 that closes a switch again, hawser is on the alert, when hawser 7 is cut off, the relay J outage, normally-closed contact J1 closure, loudspeaker L sends alarm signal, and display lamp D extinguishes simultaneously.

The diameter of the utility model stem stem can be 0.8～1mm, and the thickness of exoperidium can be 0.3～0.5mm.
