Description

Technical Field

[0001] The utility model relates to the technical field of parts detection, in particular to a parts detection device for a wheeled tractor. Background Technique

[0002] A wheeled tractor is a type of tractor, that is, a tractor with wheeled running devices. (Different from a crawler tractor) It has various forms such as two-wheel (walking tractor) and four-wheel. It is also divided into rear-wheel drive and four-wheel drive. Large-horsepower wheeled tractors have good traction performance and are suitable for large farms to be equipped with wide-width farm implements for high-speed operation. Therefore, tires are provided on the wheeled tractor. A tire is an annular elastic rubber product that is mounted on various vehicles or machinery and rolls on the ground. It is usually installed on a metal rim, can support the vehicle body, buffer external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. When it is running, it bears various deformations, loads, forces, and high and low temperatures. During the driving process of an automobile, the tire is in a high-speed rotating state. When a tire fails, it often causes extremely serious traffic safety accidents. Tire failures are often caused by abnormal air pressure inside the tire. When the air pressure is too low, the air pressure inside the wheel is unstable and the tire is prone to bursting. When the air pressure is too high, it will affect the shock absorption effect. Tire failures are the most lethal and the most difficult to prevent accident hazards. Therefore, it is very necessary to monitor the air pressure of the tires inside the vehicle in real time.

[0003] Chinese utility model patent: The publication number is CN219214629U, which discloses a tire tire pressure detection device, including a tire pressure detector. A connecting pipe is provided at the top of the tire pressure detector. A connecting head is provided at the top of the connecting pipe. A slot is opened on the top surface of the connecting pipe. The slot is an annular structure. A clamping groove is opened at the bottom end inside the slot. A protective cover is sleeved outside the connecting head. A protrusion is provided at the bottom of the protective cover. The protrusion is an annular structure. A clamping block is provided on the outer bottom surface of the protrusion. One end of the clamping block extends into the protrusion and is slidably connected thereto.

[0004] In the existing technology, when CN219214629U is in use, by setting a protective cover outside the connecting head and using the slot, clamping groove, protrusion and clamping block, the clamping of the protective cover is realized, so that it can stably cover outside the connecting head to form stable protection, thereby preventing foreign objects from entering the inside of the connecting head and causing the inability to detect the tire pressure, and playing a good protective function. However, during the tire pressure monitoring, since it is necessary to push against the valve core so that the high-pressure gas in the tire can enter the detection device, when the detection device is separated from the tire valve core, a large amount of air will quickly escape through the valve core, resulting in the problem that the air pressure of the tire will decrease after the tire pressure detection. Therefore, a parts detection device for a wheeled tractor is needed to solve the above problems. Summary of the Utility Model

[0005] The purpose of the present utility model is to provide a detection device for parts of a wheeled tractor, which has the advantage of reducing the loss of gas in the tire when detecting the tire pressure, and solves the problem of the tire pressure decreasing after the tire pressure detection.

[0007] The electric telescopic rod is fixedly installed at the top inside the connecting pipe; wherein, a sealing plug is fixedly installed at the top of the electric telescopic rod.

[0008] When using the detection device for parts of a wheeled tractor in this technical solution, align the sleeve with the vehicle tire and thread the sleeve onto the valve core of the vehicle tire. At this time, the connecting pipe is kept in communication with the valve core through the sleeve. The operator presses the start switch to start the electric telescopic rod, so as to push the valve core through the electric telescopic rod, so that the high-pressure gas in the tire can enter the connecting pipe and then enter the pressure gauge. At this time, the tire pressure can be displayed on the pressure gauge. After the tire pressure detection, the start switch can be restarted to make the electric telescopic rod contract and release the valve core, so that the high-pressure gas in the tire cannot enter the connecting pipe. At this time, the sleeve is unscrewed from the valve core, and then the separation of the connecting pipe from the tire is realized.

[0009] Preferably, an external thread is provided at the top of the outer wall of the connecting pipe and a sealing cover is threadedly installed, and a handle is fixedly installed on the other side of the connecting pipe.

[0016] By arranging a gasket inside the sleeve and sleeving the gasket on the connecting pipe, after connecting the sleeve to the tire valve core, the gasket can prevent the high-pressure gas inside the tire from discharging.

[0017] Preferably, the electric telescopic rod is driven by direct current, and the outer diameter size of the electric telescopic rod matches the inner diameter size of the connecting pipe.

[0018] By setting the outer diameter of the electric telescopic rod to be the same as the inner diameter size of the connecting pipe, it is convenient to install the electric telescopic rod on the connecting pipe and prevent the telescopic direction of the electric telescopic rod from deviating inside the connecting pipe.

[0019] Preferably, a battery compartment is embedded and installed inside the sealing plug. The battery compartment is electrically connected to the electric telescopic rod and the start switch. The sealing plug is designed with a soft rubber material, and the top of the sealing plug is fixedly connected to the top inner wall of the sealing cover.

[0020] By arranging a battery compartment inside the sealing plug, the battery inside the battery compartment can supply power to the electric telescopic rod. At the same time, the sealing plug can also improve the sealing performance after the sealing cover is connected to the connecting pipe.

[0021] Compared with the prior art, the beneficial effects of the present utility model are as follows:
