Description

Technical Field

[0001] The utility model relates to the technical field of tire pressure detection of air valves, 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 while the car is driving, 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 also a defect that after installing the joint and tire pressure detection device, the counterweight increases, 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. Utility Model Content

[0005] The tire pressure monitoring structure of the present invention is characterized in that: the tire pressure monitoring structure of the tire pressure monitoring structure is a tire pressure monitoring structure, the tire pressure monitoring structure comprising a connecting block mounted on the wheel rim, the tire pressure monitoring structure being fixedly provided with an air valve, a connecting port being provided on the air valve, a rubber protective sleeve being fixedly provided on the air valve, the connecting block being provided with a connecting groove, the connecting groove being communicated with the connecting port, the air outlet groove being provided on the wheel rim, the connecting ring being fixedly provided in the connecting groove, the connection being provided with a stabilizing groove, a tightening rod being inserted in the connecting groove, a contact plate being fixedly provided on the tightening rod, when the tightening 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 tightening rod is provided with an air intake channel, the air intake 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 contacts the side wall of the air groove, which can reduce the movement of the connecting block. 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 greater 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 into the rubber protective sleeve. When the connecting block contacts the bottom of the air groove, the upper side of the stabilizing sleeve contacts the mounting ring and the lower side contacts the air nozzle. The tightening 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, while protecting the mounting ring and reducing 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 fits tightly on the rim, further reducing the movement of the connecting block and reducing valve fatigue.

[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 greater damage to the air nozzle due to excessive shaking, thereby achieving the effect of reducing fatigue and damage to the air nozzle.
