Abstract
The utility model relates to a device for alarming when a trailer tyre not in full inflation, which comprises a signal receiver, installation parts thereof, an alarm and conducting wires, wherein, the signal receiver is fixedly installed on a wheel shaft by the installation parts. When a tyre is not in full inflation, a loop is switched on, and the alarm gives an alarm to inform a driver for dealing with. The utility model has the advantages of simple structure and high accuracy, and really solves the problem that the driver can not discover when the trailer tyre is not in full inflation. The utility model can be widely used as a device for alarming when the tyre not in full inflation for the trailers of various motor vehicles.
Description
The utility model relates to a kind of tire and loses the gas warning device.
Have a variety of motor vehicle rears to hang with trailer, trailer is far away from operator's compartment, and tire loses gas, and the driver is difficult to realize.Therefore, after often tire did not have gas, the driver still drove to overtake, and the wheel iron ring lands not only to grind away and do not have the tire of gas like this, and destroyed the road surface, caused very big economic loss.Therefore, to lose the problem that gas can not be realized by the driver be that numerous drivers are worried to trailer tire always.
The purpose of this utility model provides a kind of trailer tire simple in structure, that accuracy is high and loses the gas warning device.
The purpose of this utility model is to realize like this.A kind of trailer tire loses the gas warning device, it is characterized in that; It comprises signal receiver; the signal receiver fabricated section; annunciator; lead; described signal receiver comprises two sections rigid insulation rods; flexible pipe; rod contacts to earth; sheetmetal; switch contact; protection sleeve; described flexible pipe is fixedly connected between two sections rigid insulation rods; described sheetmetal is arranged in described flexible pipe; and be fixed between described two sections rigid insulation rods; described switch contact is positioned at the sheetmetal opposite and is vertically fixed on the described hose inner wall; the described rigid insulation rod that is installed together; the sealing of flexible pipe outside is with protection sleeve; the part that described protection sleeve is positioned at the flexible pipe place at least is soft; the described rod that contacts to earth is captiveed joint with the rigid insulation rod of signal receiver one end; the other end of described signal receiver is captiveed joint with described fabricated section, and the sheetmetal switch contact of described signal receiver is formed series loop by the lead and the described annunciator that pass described rigid insulation rod.
Described annunciator is the annunciator that has the speech IC piece.
Described annunciator is a display lamp.
Described protection sleeve is a plastic film capicitor.
The described rod that contacts to earth is to have the adjustable-length iron wire that spiral twines section.
When the utility model uses, by fabricated section the signal receiver vertical ground is fixedly mounted on the axletree, make the excellent built on stilts that contacts to earth, car body moves down when tire loses gas, the rod that contacts to earth contacts to earth, because car to overtake, epimere rigid insulation rod together moves ahead with axletree, and hypomere rigid insulation rod is delayed under the effect of contact to earth rod and frictional ground force, so the flexible pipe part is crooked, the sheetmetal reversing sense arches upward, the switch contact contact metal film, circuit is connected, and at this moment is installed in frame and sails indoor annunciator, promptly can send signal, notify the driver.The utility model is owing to adopt above-mentioned design plan, fully avoided trailer tire to lose gas and problem that the driver can not realize, and it is simple in structure, in addition, because the switch sections of signal receiver is sealed in the flexible pipe, therefore can not be subjected to sandstone, the influence of rainwater produces flase alarm, so accuracy is very high.
Below in conjunction with accompanying drawing the utility model is described in detail:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model fabricated section schematic top plan view.
Fig. 3 uses erection plan for the utility model.
As shown in Figure 1, by rigid insulation rod 1,1 ', flexible pipe 2, have spiral and twine the tensile iron wire 3 that contacts to earth of section, sheetmetal 4, switch contact 5, corrugated tube 6 are formed signal receiver 7.Described flexible pipe 2 be fixedly connected on described rigid insulation rod 1,1 ' between; described sheetmetal 4 is arranged in described flexible pipe 2; and be fixed on described two sections rigid insulation rods 1,1 ' between; described switch contact 5 is positioned at described sheetmetal 4 opposites and is vertically fixed on described flexible pipe 2 inwalls; the described hard metal rod that is installed together 1,1 ', flexible pipe 2 outsides sealings is with corrugated tube 6, described contact to earth iron wire 3 and described rigid insulation rod 1 ' captive joint.Described sheetmetal 4, switch contact 5 are formed series loop, described signal receiver 7 one end captive joints one fabricated section 8 by lead that passes described rigid insulation rod 1 and the annunciator that has the speech IC piece 9 that is positioned at the driver driving chamber.
In the foregoing description, speech sound signal in the speech IC piece in the annunciator 8 can be the output that lags behind, and when switch is temporarily connected, can not send voice signal immediately, can avoid like this because of the road injustice, contact to earth the iron wire swinging earth and the flase alarm that causes.Annunciator can also substitute with display lamp etc. in addition, as long as can give signal of driver.Utilize display lamp to make the utility model of annunciator, if the road injustice, the iron wire swinging earth of contacting to earth, display lamp only can be glittering discontinuously, and the driver also is easy to judge.
As shown in Figure 3, when the utility model uses, utilize fabricated section 8 that signal receiver 7 is fixed on tire next door on the trailer tire axle 10, mix up the length of the iron wire that contacts to earth according to the size of tire, each tire is other can respectively be installed a signal receiver and signal receiver can be together in parallel with lead, then with operator's compartment in annunciator be composed in series the loop.Also but each signal receiver is connected with an annunciator respectively, and in parallel then and power supply joins.
