[0007] Preferably, a fixing rod is fixedly connected to the outer arc surface of the buckle; a telescopic cavity is provided at the active end of the fixing rod; so that the telescopic rod can operate smoothly.

[0008] Preferably, a telescopic rod is slidably installed inside the telescopic cavity; a support block is fixedly connected to the end of the telescopic rod, thereby achieving an auxiliary fixing effect.

[0022] When working, the sealing structure of the supporting wheel refers to the design used to prevent the leakage of lubricating oil or grease and prevent external impurities from entering the bearing system, which is very important for protecting the internal bearing system and extending the service life; during the use of the sealing structure of the above-mentioned supporting wheel, once the sealing structure leaks, the operator cannot discover it in time, causing the lubricating oil to leak and causing unnecessary losses. The present application works through an auxiliary device, and uses the buckle 406 to make the rubber ring 401 close to the sealing structure of the wheel body 1, so that the color developing reagent cotton 405 is close to the wheel body 1. Once the sealing structure of the supporting wheel leaks, the lubricating oil will be absorbed by the color developing reagent cotton 405, and the color developing reagent cotton 405 will change color, which slows down the leakage speed of the supporting wheel sealing structure and reduces unnecessary losses. At the same time, the operator can observe the color developing reagent cotton 405 after the color change through the structural hole 403 and the transparent membrane 404, which is convenient for the operator to quickly check and achieve the effect of timely replacement.

[0024] During operation, the inclined end of the support block 410 is inserted into the structure of the wheel body 1. When the buckle 406 is clamped in the structure of the wheel body 1, the support block 410 is pushed into the mechanism of the wheel body 1, so that the telescopic rod 409 moves toward the telescopic cavity 408 of the fixed rod 407. Under the action of the fixed plate 412, the spring 411 is compressed, so that the rubber ring 401 can operate stably.

[0025] Working principle: The sealing structure of the supporting wheel refers to the design used to prevent the leakage of lubricating oil or grease and prevent external impurities from entering the bearing system. It is very important for protecting the internal bearing system and extending the service life. During the use of the sealing structure of the above-mentioned supporting wheel, once the sealing structure leaks, the operator cannot find it in time, causing the leakage of lubricating oil and unnecessary losses. The present application works through the auxiliary device to insert the inclined end of the support block 410 into the structure of the wheel body 1, and use the buckle 406 to make the rubber ring 401 close to the sealing structure of the wheel body 1, so that the color reagent cotton 405 is close to the wheel body 1. In this process, the support block 410 is pushed into the mechanism of the wheel body 1, so that the telescopic rod 409 moves into the telescopic cavity 408 of the fixed rod 407. Under the action of the fixed plate 412, the spring 411 is compressed, so that the rubber ring 401 can operate stably. Once the sealing structure of the supporting roller leaks, the lubricating oil will be absorbed by the color developing reagent cotton 405 and the color developing reagent cotton 405 will change color, which slows down the leakage speed of the supporting roller sealing structure and reduces unnecessary losses. At the same time, the operator can observe the color developing reagent cotton 405 after the color change through the structural hole 403 and the transparent membrane 404, which is convenient for the operator to quickly check and achieve the effect of timely replacement.
