Description

  The present invention relates to a tire pressure detection device, and more particularly to a tire pressure detection device that detects fluid pressure.

  Normally, when a vehicle traveling on a road has traveled for a long period of time, some parts of the vehicle body are worn, damaged, or in a state that requires repair. Tire inspection and repair are also part of vehicle maintenance.

  At present, inspection and measurement of tire air pressure in tire inspection and repair are performed using a tire air gauge. The tire air gauge includes a switch provided above, a pressure gauge, and two openings.

  The opening has one end connected to the tire valve via a conduit and the other end connected to the air compressor via the conduit. Therefore, when the air in the air compressor is compressed and sent to the tire air gauge and the tire air gauge is turned on, the compressed air is sent to the tire. At the same time as air is sent, the pressure value in the tire is measured with a pressure gauge.

  However, when the pressure gauge is used for a long period of time, a deviation occurs in the measured value. Therefore, if the numerical value is not corrected appropriately, the actual pressure in the tire may not be normal even if the numerical value displayed on the pressure gauge is normal. Differences occur.

  In the situation described above, the vehicle using the tire travels with insufficient tire pressure, so there are situations such as travel, response slowing, vehicle operation becomes difficult, and gasoline usage increases. appear. On the other hand, if the tire pressure is significantly higher than the normal value, there is also a risk that the tire will burst during travel.

  This invention makes it a subject to provide the tire pressure detection apparatus which can judge whether a tire pressure is normal with several pressure gauges.

Therefore, as a result of intensive research in view of the drawbacks found in the prior art, the present inventor, as a result, a bifurcated seat with a penetrating airway,

The connection pipe 22 includes a hole penetrating through the center, a thread groove formed at the outer peripheral edge of one end, and a connector 23 provided at the other end. Therefore, the pressure gauge 21 can be quickly connected or removed using the connector 23.

  The connecting means 30 is formed by connecting a one-way valve 31, a pressure regulating valve 32, and a guide hole 33 in order. The unidirectional valve 31 restricts the gas to flow in a single direction, and the pressure regulating valve 32 adjusts the flow amount of the gas. In addition, the one-way valve 31 has a thread groove formed at an end edge facing the end edge connected to the pressure regulating valve 32.

  The valve 40 has a guiding action when connected to the guide tube, and the valve 40 is provided with a thread groove on the outer peripheral surface of the edge portion facing the edge portion connected to the guide hole.
