Abstract
The utility model discloses an early warning monitoring instrument for the over pressure and the gas leakage of a tyre, which is composed of a bidirectional reception display with integration probe and multiple channels, and the bidirectional reception display is composed of a bidirectional air pressure switch and a coded transmitter. The integration probe is connected with a tyre air valve. When the over pressure and under pressure which namely are the gas leakage is happened in the tyre, an air pressure switch is actuated, the coding circuit of a transmitter works to send out coded signals to a receiver, and alarm signals are sent out by a loudspeaker and a nixie tube after the coded signals are received by the receiver. A driver can quickly judge which tyre is in the over pressure or the under pressure via the display number of the nixie tube and quickly process. The utility model has the advantages of simple structure, convenient installation and safe utilization.
Description
The utility model relates to a kind of vehicle tyre overvoltage, under-voltage early warning monitor unit.
Vehicle under steam, owing to causing the tire internal gas pressure, factors such as road surface, weather change overvoltage, the under-voltage situation of occurring, can not in time find for the driver, and cause the phenomenon of blowing out, pricking tire, broken tire, thereby cause traffic accident, cause casualties and the accident of property damage happens occasionally, thus the designing tyre overvoltage, because of gas leakage undervoltage warning device necessary.And present designed warning device, general only undervoltage warning to producing because of tire flat, and to the overpressure situation warning excessive because of pressurizeing, that temperature build-up produces.
The purpose of this utility model aims to provide a kind of simple in structure, easy for installation, safe and reliable, can be to the warning device of tire overvoltage, under-voltage enforcement early warning supervision.
The purpose of this utility model realizes that in the following manner tire overvoltage, gas leakage early warning monitor are made of probe projector, receiver, display part.Two-way baroswitch and coded transmitter constitute integrated probe.The atmospheric pressure cavity of two-way baroswitch (2) is by resistance to compression flexible pipe 6, thimble 7 and tire valve 8 conductings.Feeler lever 3, contact 4,5 respectively with coded transmitter contact A, C conducting, contact A, C connect integrated package
