Abstract
The utility model discloses a gas pressure meter for a vehicle tyre, composed of a pressure meter, a connecting pipe and a pressure tapping device. The utility model is characterized in that the pressure meter is communicated with the pressure taking device through the connecting pipe, and the pressure taking device is composed of a gas nozzle valve core and a gas nozzle joint which are fixed in the connecting pipe. The utility model can conveniently and accurately measure the gas pressure in a vehicle tyre, and the gas pressure value of a measured tyre can be accurately adjusted during the measurement simultaneously, so that the gas-pressure balance of vehicle tyres on both sides can be guaranteed, and the driving safety can be ensured.
Description
The utility model relates to a kind of device of measuring pulley air pressure.
At the automobile of running on expressway, the equilibrium phase that keeps its both sides tire pressure is when important.At present the barometric surveying means behind the inflation of tire have two kinds: a kind ofly directly indicated by the compression indicator on the Air compressor, another kind is by the air pressure tape measure, and the precision of these two kinds of method of measurement is low, can not accurately adjust the tire pressure value.
The purpose of this utility model is a kind of survey precision height of design, can adjust the device of tire internal gas pressure value when measuring easily and accurately.
The technical scheme that realizes the utility model purpose comprises compression indicator and pressure obtaning device, compression indicator is communicated with pressure obtaning device by connecting pipe, pressure obtaning device is made of valve spool that is fixed on connecting pipe one end and valve joint, and the valve interface of Xing Chenging is communicated with the centre hole of connecting pipe between the two.
The utility model has the advantages that and carry, measure conveniently, during measurement the valve joint is aimed at cranked tire valve and compressed the air pressure that can measure in the tire, the atmospheric pressure value of the both sides tire of general vehicle differs can be very not big, so the utlity model has higher accuracy of measurement.And only need reduce the thrust of tire pressure gauge and detected tyre, the air pressure in the detected tyre just can drop to required atmospheric pressure value from bleeding off between the two, can make things convenient for the air pressure balance of adjusting vehicle both sides tire exactly, guarantees traffic safety.
Fig. 1 is a structural representation of the present utility model.
Now describe embodiment of the present utility model in conjunction with the accompanying drawings in detail.Tire pressure gauge as shown in Figure 1 is made of compression indicator 6, connecting pipe 4 and pressure obtaning device.Compression indicator 6 is connected by the threaded one end of pressure tap 5 with connecting pipe 4, and there is through hole at connecting pipe 4 centers, and its other end is fixed with valve spool 3 and valve joint 1, is press-fiting a grommet type seals 2 between the two, and constitutes two valve interfaces of symmetry.On valve spool 3, be shaped on air extractor vent or air channel, be communicated with the centre hole of valve interface and connecting pipe 4.
Connecting pipe 4 adopts plastic material, and valve spool 3 and valve joint 1 adopt copper or stainless steel material.
