Abstract

Disclosed is a theft alarm of cargo vehicle, which comprises an alarm circuit and a triggering circuit, and the wires forming the loop of the triggering circuit are clamped in the cables bundling a cargo or in the net twines of a cargo-blocking net. The wires in the cables are spliced with the triggering circuit. The alarm circuit comprises a cascaded loop of a power supply, a switch, an alarm lamp and a normally closed switch, and the triggering circuit comprises a cascaded loop of a power supply, a switch, a relay capable of controlling the normally closed switch of the alarm circuit and wires clamped in the cables. When a criminal cuts the cables bundling the cargo, the alarm circuit warns instantly, so a driver in the cab can immediately discover and stop the criminal act, and the cargo can be prevented from being stolen.

Description

Theft alarm of cargo vehicle

The utility model relates to a kind of burglar alarm, particularly lorry goods burglar alarm.

Have only indoor burglar alarm in the prior art, report to the police with warning circuit triggering sound, light.But the burglar alarm that does not have open-air goods, goods in travelling on lorry does not have anti-theft device especially, so, when lorry travels, when particularly travel night on road outside of the city, often there is the offender to climb up car, cuts off the goods hawser, the goods of theft on the car, and known to the driver usually has no.

The utility model has proposed a kind of lorry goods burglar alarm at the deficiencies in the prior art.

Task of the present utility model is achieved in that the utility model is a kind of lorry goods burglar alarm, comprises warning circuit and trigger circuit device, and the lead that constitutes the trigger circuit loop is to be clipped in the bundle goods hawser or to be clipped in the nettle of goods-blocking net.

The warning circuit of said apparatus and trigger circuit are located in the pilothouse, peg graft between lead in the rope and the trigger circuit.

The warning circuit of said apparatus comprises power supply, switch, warning electroacoustic light device, the normally closed switch loop that is connected in series, trigger circuit comprise the power supply that is connected in series, switch, may command warning circuit normally closed switch relay, be clipped in the wire loop in the rope.

The battery dry cell of warning circuit, the battery of trigger circuit is with the accumulator on the lorry.

The utility model compared with prior art, owing to being clipped in, the return wire with warning circuit has camouflage property and obstacle in the goods hawser, when the offender cuts off bundle car rope, warning circuit in the pilothouse is reported to the police immediately, the driver or the personnel that escort goods on a train, truck, etc. just can in time find and prevent criminal offence, and are stolen in transit to prevent goods.When the warning circuit dry cell, trigger circuit can prevent that also criminal from stealing the accumulator on the car during with the accumulator on the lorry.

Fig. 1 is a kind of structural representation of the present utility model.

Fig. 2 is a kind of circuit diagram of the present utility model.

Fig. 3 is an another kind of structural representation of the present utility model.

Fig. 4 is an another kind of circuit diagram of the present utility model.

Fig. 1, Fig. 2 embodiment one of the present utility model.Lorry goods burglar alarm among the figure comprises warning circuit and trigger circuit device, and the lead that constitutes the trigger circuit loop is (7) that are clipped in the bundle goods hawser.Warning circuit and trigger circuit are located in the pilothouse, and trigger circuit electric wire two ends sockets (5,6) are contained in the front-end and back-end, compartment respectively, and there is plug at the lead two ends in the rope.Warning circuit comprises the power supply (9) that is connected in series, switch (10), the alarm lamp (2) and alarm sound (3), the normally closed switch loop that are in parallel, trigger circuit comprise the power supply that is connected in series, switch (8), may command warning circuit normally closed switch relay (4), be clipped in the wire loop of (7) in the rope.The battery of warning circuit (9) is used dry cell, and the battery of trigger circuit is with the accumulator on the lorry.Alarm lamp and alarm sound are contained on the bridge (1).

Fig. 3, Fig. 4, embodiment of the present utility model two.Among the figure, be lorry goods burglar alarm of the present utility model, comprise warning circuit and trigger circuit device, the lead that constitutes the trigger circuit loop is to be clipped in the nettle of goods-blocking net (17).Warning circuit and trigger circuit are located in the pilothouse.Trigger circuit electric wire two ends sockets (15,16) are contained in the front-end and back-end, compartment respectively, and there is plug at the lead two ends in the nettle.Warning circuit comprises the power supply (18) that is connected in series, switch (19), the alarm lamp (12) and alarm sound (13), the normally closed switch loop that are in parallel, trigger circuit comprise the power supply (18) that is connected in series, switch (19), may command warning circuit normally closed switch relay (14), be clipped in the wire loop in the nettle.Warning circuit is that its power supply (18) is accumulator or the dry cell in the lorry body with identical power supply (18) and switch (19) with trigger circuit.Alarm lamp (12) is contained on the bridge (11) with alarm sound (13).

During use, tied goods, with the plug at rope or net two ends with bundle goods hawser or goods-blocking net, one end is inserted on the socket before the compartment, and the other end is inserted on the socket behind the compartment, opens warning circuit and trigger circuit switch, total system enters duty, the trigger circuit energising, relay disconnects the normally closed switch in the warning circuit, is cut off as bundle goods hawser or goods-blocking net nettle, trigger circuit disconnect, relay quits work, the normally closed switch closure in the warning circuit, and warning circuit is reported to the police immediately.
