Abstract
The utility model relates to a monitoring and alarming device for trailer tyre pressure, comprising power source, a switch, a buzzer, guiding wire and a monitor; the bottom of a case is sealed by a sealing cover, and a clapboard is arranged on one end near the sealing cover in the case; a leading wire is passed from the case between the sealing cover and the clapboard, then passed the clapboard to connect a tactile head, and silver balls are arranged in one side of the tactile head in the case. The utility model has the advantages of simple structure, convenient installation, steady performance and high sensitivity; the damage or discarding can be prevented by decompression of the tyre, the utility model is widely used for various trailers and analogous vehicles.
Description
The utility model belongs to the air pressure monitor unit, is specifically related to a kind of trailer tire pressure monitoring alarmer, is specially adapted in trailer or the similar vehicles communications and transportation, to the monitoring of tire pressure.
Usually, the trailer of automobile trailer or trac. does not have the tire air pressure monitoring device, in communications and transportation, because low tyre, and makes damaged tyres or the phenomenon of scrapping happens occasionally, and causes bigger economic loss for country and unit.
The purpose of this utility model is exactly in order to address the above problem, a kind of trailer tire pressure monitoring alarmer is provided, when tire pressure descends, annunciator generation alarm, remind the driver that air pressure of automobile tire is supplied, thereby avoid tire not enough or do not have gas, roll for a long time and the damage that causes or scrap because of air pressure.
The purpose of this utility model is achieved in that the trailer tire pressure monitoring alarmer is made up of power supply, switch, buzzer phone, monitoring device, lead, also can replace buzzer phone by indicator lamp.
Monitoring device of the present utility model is by housing, seal cover cap, dividing plate, lead-in wire, contact and mercury bead are formed, the bottom of housing seals with seal cover cap, dividing plate is loaded on an end of close seal cover cap in the housing, lead-in wire is by the housing between seal cover cap and the dividing plate, pass dividing plate afterwards and be connected with contact, mercury bead is loaded on contact one side in the housing.
Fig. 1 is a circuit diagram of the present utility model.
Fig. 2 is the structural representation of the utility model monitoring device.
