Description

Technical Field

[0001] The present invention relates to the technical field of tire pressure detection of air valves, and in particular to a tire pressure detection structure for rubber air valves. Background Art

[0002] Nowadays, common electric motorcycles, electric bicycles, and cars use rubber air valves. In order to improve the safety of the car, TPMS is usually installed in the car. TPMS stands for tire pressure monitoring system. The function of TPMS is to automatically monitor the tire pressure in real time during the driving of the car, and to alarm for tire leakage and low pressure to ensure driving safety. The detection head of the common TPMS is installed on one end of the air valve, the air valve is fixed on the rim, and the detection head is located in the tire. After the detection head detects the inside of the tire, the detection data is transmitted to the TPMS for processing to determine whether the vertical pressure inside the tire is normal.

[0003] Regarding the above technical conditions, there is still a defect that after adding the joint and the tire pressure detection device, the counterweight is increased, the swing of the air nozzle increases when the tire rotates, and the centrifugal force increases, which can easily cause the rubber nozzle to fatigue and break, resulting in air leakage.

[0004] Based on this, the present invention designs a tire pressure detection structure for a rubber air valve to solve the above problems. Summary of the invention

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a tire pressure detection structure for a rubber air valve, comprising a connecting block installed on the rim, the air valve being fixedly arranged on the rim, the air valve being provided with a connecting port, the air valve being fixedly arranged on the air valve, the connecting block being provided with a connecting groove, the connecting groove being communicated with the connecting port, the wheel rim being provided with an air outlet groove, a mounting ring being fixedly arranged in the connecting groove, a stabilizing groove being provided on the connection, a clamping rod being inserted in the connecting groove, a contact plate being fixedly arranged on the clamping rod, when the clamping rod is threadedly connected to the connecting port, the contact plate is pressed against a side of the mounting ring away from the air valve, the rubber protective sleeve is located in the stabilizing groove, the connecting block flattens the rubber protective sleeve downward, the connecting block is pressed against the bottom of the air outlet groove, the clamping rod is provided with an air inlet channel, the air inlet channel is communicated with the connecting port, and a detection head is provided on the connecting block.

[0006] By adopting the above technical solution, the connecting block is in contact with the side wall of the air groove, which can reduce the movement of the connecting block. At the same time, the clamping plate is pressed against the mounting ring, which can further reduce the movement of the connecting block. The detection head is installed on the connecting block, thereby effectively avoiding serious damage to the air nozzle due to excessive shaking, thereby achieving the effect of reducing fatigue damage to the air nozzle.

[0007] Preferably, a stabilizing sleeve is inserted in the rubber protective sleeve, and when the connecting block abuts against the bottom of the air groove, the upper side of the stabilizing sleeve abuts against the mounting ring, and the lower side abuts against the air nozzle, and the clamping rod is located in the stabilizing sleeve.

[0008] By adopting the above technical solution, the stabilizing sleeve can reduce the movement of the mounting ring, and at the same time protect the mounting ring and reduce the wear of the mounting ring.

[0009] Preferably, the connecting block is an arc-shaped block, and one side of the connecting block is attached to the rim.

[0010] By adopting the above technical solution, the connecting block is tightly fitted on the rim, further reducing the movement of the connecting block and reducing the fatigue of the air nozzle.

[0011] To sum up, the present application has the following beneficial technical effects: the connecting block abuts against the side wall of the air groove, which can reduce the movement of the connecting block, and at the same time, the clamping plate presses against the mounting ring, which can further reduce the movement of the connecting block. The detection head is installed on the connecting block, thereby effectively avoiding major damage to the air nozzle due to excessive shaking, thereby achieving the effect of reducing fatigue and breakage of the air nozzle.
