The use of hydraulic jacking in transportation equipment faces many limitations such as large space requirements and high cost of hydraulic system. The use of high-pressure water hoses for inflation lifting has great advantages, such as high safety, low space requirements, lower jacking air pressure than hydraulic pressure, and the ability to use the vehicle's existing air source at a low cost. However, inflation lifting has high requirements on the sealing structure of the inflation port, and a sealing structure with an inflation port is proposed. Utility Model Content

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1-3 As shown, a sealing structure with an inflation port includes a fixing bolt 2 and a sealing air belt 6, an upper splint 4 is arranged on the upper part of one end of the sealing air belt 6, and a lower splint 7 is arranged on the lower part of one end of the sealing air belt 6, the fixing bolt 2 passes through the upper splint 4, the sealing air belt 6 and the left and right sides of the lower splint 7, and the lower part of the fixing bolt 2 is threadedly connected with a fixing nut 3, and the fixing nut 3 is arranged at the lower part of the lower splint 7. In summary, after the sealing block 5 is drilled out with a mounting hole 8, the air joint 1 and the sealing block 5 are connected through the mounting hole 8, and then the sealing block 5 is embedded in the sealing air belt 6, and then the upper splint 4 and the lower splint 7 are placed on the upper and lower sides of the sealing air belt 6, and then the fixing bolt 2 is passed through the upper splint 4, the sealing block 5, the sealing air belt 6 and the lower splint 7, and finally the fixing nut 3 is tightened so that the upper splint 4, the lower splint 7 and the sealing block 5 are clamped and squeezed with each other to achieve a pressure-bearing seal. If the closed end is used in a closed manner, only the air joint 1 and the sealing block 5 are omitted.

[0019] A gasket is provided at the lower part of the fixing bolt 2, and the gasket is provided between the fixing nut 3 and the lower clamping plate 7. By providing the gasket, the fixing nut 3 is prevented from loosening, resulting in the fixing bolt 2 being unable to clamp the upper clamping plate 4 and the lower clamping plate 7 to clamp the sealing air belt 6, thereby effectively ensuring long-term sealing. A sealing block 5 is provided at one end of the sealing air belt 6, and a mounting hole 8 is opened in the middle of the sealing block 5. An air joint 1 is provided inside the mounting hole 8. Through the above combination, they are squeezed against each other to achieve inflation sealing. The sealing block 5 is provided between the upper clamping plate 4 and the lower clamping plate 7. The diameter of the mounting hole 8 is 0.5mm to 1mm smaller than the diameter of the air joint 1, so that the air joint 1 can be firmly fixed inside the mounting hole 8. The air joint 1 is connected to an external air source, and the existing air source of the vehicle itself is utilized without repeated investment.

[0020] Working principle:

[0021] After drilling the mounting hole 8 in the sealing block 5, connect the air joint 1 and the sealing block 5 through the mounting hole 8, and then embed the sealing block 5 into the sealing air belt 6, and then place the upper clamp 4 and the lower clamp 7 on the upper and lower sides of the sealing air belt 6, and then pass the fixing bolt 2 through the upper clamp 4, the sealing block 5, the sealing air belt 6 and the lower clamp 7, and finally tighten the fixing nut 3, so that the upper clamp 4, the lower clamp 7 and the sealing block 5 are clamped and squeezed with each other to achieve a pressure-bearing seal. If the closed end is used in a closed manner, only the air joint 1 and the sealing block 5 are omitted.

[0022] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
