Abstract

The utility model discloses an air pressure monitor for a tyre, which is composed of a metal housing body, a sealing gasket, a metal supporting rod, a movable contact point, a diaphragm, a spring, regulating screws, a battery, a transmitting module, a bottom cover, a plastic barrel, a metal inner ring and a receiving alarm. The utility model has the advantage that the utility model can monitor and alarm for the air pressure of an automobile tyre at any moment, and the utility model has the advantages of simple structure, easy manufacture, low price and convenient use. When the air pressure monitor for a tyre is used, the receiving alarm is installed in an automobile cab, and the metal housing body is directly installed on the air valve of the automobile tyre. When an automobile leaks air, signals transmitted by the transmitting module are received by the receiving alarm, and the receiving alarm alarms.

Description

The tire air pressure monitoring device

The utility model relates to a kind of air pressure of automobile tire monitoring device, belongs to the vehicular spare parts field.

At present, motor tire of the prior art does not have air pressure monitoring device mostly owing to there is not an air pressure alarm device, when automobile in the process of moving tire leak air, when blowing out, chaufeur can not in time be gone and found out what's going on and be taked measures necessary, thereby is easy to occur the traffic accident accident.And existing some air pressure of automobile tire detecting device when the detection wheel air pressure, need stop automobile, just can keep away row and detect, thereby use very inconvenient.

The purpose of this utility model is: a kind of tire air pressure monitoring device that can monitor, report to the police air pressure of automobile tire at any time is provided.

The utility model is to constitute like this: it is by metal shell (1), tightening seal washer (2), metallic carrier rod (3), moving contact (4), diaphragm (5), spring (6), set screw (7), battery (8), transmitter module (9), bottom (10), plastic barrel (11), metal inner ring (12), receiving annunciator (13) forms, at metal shell (1) plastic barrel (11) is housed, tightening seal washer (2) is contained between metal shell (1) and the plastic barrel (11), metallic carrier rod (3) is fixed on the plastic barrel (11), through hole (14) is arranged on metallic carrier rod (3), be connected with the inner hole wall of plastic barrel (11) around the diaphragm (5), moving contact (4) is fixed on the diaphragm (5), spring (6) contacts with set screw (7) with moving contact (4), set screw (7) is contained in the hole of metal inner ring (12), metal inner ring (12), battery (8), transmitter module (9) all is contained in the plastic barrel (11), metal inner ring (12) contacts with battery (8), battery (8) contacts with transmitter module (9), transmitter module (9) contacts with bottom (10), and bottom (10) is contained on the metal shell (1); To receive annunciator (13), to be contained in vehicle drive indoor.

The utility model compared with prior art has the advantage that can detect, report to the police air pressure of automobile tire at any time, and it also has advantage simple in structure, that the making visitor is easy, cheap, easy to use.To receive annunciator (13) during use, to be installed in vehicle drive indoor, metal shell (1) is directly installed on the tire tube valve of motor tire, at this moment metallic carrier rod (3) will be backed down the spool in the tire tube valve, tire pressure is acted directly on the diaphragm (5), when automobile leaks gas, air pressure reduces, the moving contact (1) that is fixed on the diaphragm (5) contacts with metallic carrier rod (3) under the effect of spring (6), metallic carrier rod (3) is by valve inside and valve and metal shell (1) connection, thereby make transmitter module (9) and battery (8) form C/LOOP, at this moment transmitter module (9) sends signal, receives to send the alerting signal driver after annunciator (13) is received signal.

Accompanying drawing 1 is a structural representation of the present utility model.

Embodiment of the present utility model: battery (8), transmitter module (9), receive annunciator (13) and all adopt the finished product of selling on the market, other part is special the making, in metal shell (1), load onto plastic barrel (11), tightening seal washer (2) is contained between metal shell (1) and the plastic barrel (11), metallic carrier rod (3) is fixed on the plastic barrel (11), upper end with push rod (3) in the time of fixedly is about the bottom that exceeds plastic barrel (11), so that it contacts with moving contact (4), on metallic carrier rod (3), produce through hole (14), to bond together with the inner hole wall of plastic barrel (11) around the diaphragm (5), and moving contact (4) is fixed on the diaphragm (5), not exchanged information in the diaphragm both sides, spring (6) is contacted with set screw (7) with moving contact (4), and set screw (7) is contained in the hole of metal inner ring (1 2), with metal inner ring (12), battery (8), transmitter module (9) all is contained in the plastic barrel (11), and metal inner ring (12) is contacted with battery (8), battery (8) contacts with transmitter module (9), transmitter module (9) contacts with bottom (10), bottom (10) is gone up on the negative thread of metal shell (1).
