DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figure 1 and Figure 2 As shown, in this embodiment, a mounting plate seat for a trolley case wheel includes a plate body 1, a fixing seat 4 is symmetrically installed at the edge of the top surface of the plate body 1, a fixing screw hole 5 is opened on the top surface of the fixing seat 4, a fixing plate 2 is symmetrically fixed to the bottom surface of the plate body 1, a mounting hole 3 is opened on one end surface of the fixing plate 2, a functional component is arranged in the middle of the bottom surface of the plate body 1, the functional component includes an arc-shaped plate 6 fixed to the middle of the bottom surface of the plate body 1, a connecting card plate 7 is arranged on the inner side of the arc-shaped plate 6, the cross-sections of the arc-shaped plate 6 and the connecting card plate 7 are both arc-shaped, and the arc lengths of the arc-shaped plate 6 and the connecting card plate 7 are equal, a brush 8 is fixed at an equal distance in the middle of the bottom surface of the connecting card plate 7, and the bottom surface edge of the arc-shaped plate 6 is fixed to the fixing plate 2. Limiting blocks 9 for engaging the side edges of the connecting card plate 7 are arranged at equal distances, and the longitudinal section of the limiting block 9 is "L"-shaped. The brush 8 is fitted and connected to the surface of the box wheel. Connecting magnetic sheets 12 are symmetrically fixed at both ends of the top surface of the connecting card plate 7, and limiting slots 11 for engaging the connecting magnetic sheets 12 are symmetrically provided at both ends of the bottom surface of the arc plate 6. The surface of the connecting magnetic sheet 12 is magnetically connected to the inner surface of the limiting slot 11, and cleaning blades 10 are symmetrically fixed at both ends of the bottom surface of the connecting card plate 7. One end surface of the cleaning blade 10 is in fit with the surface of the box wheel, which is convenient for cleaning impurities attached to the surface of the box wheel, and for improving the stability of the box wheel during rotation. The functionality is improved and the practical effect is better.

[0021] like Figure 3 and Figure 4 As shown, a limit assembly is arranged between the two fixing seats 4, and the limit assembly includes a connecting sleeve 13 arranged between the two fixing seats 4, and limit screws 14 are symmetrically arranged at both ends of the connecting sleeve 13. A through groove 15 for one end of the limit screw 14 to be screwed in is symmetrically provided on one side surface of the two fixing seats 4, and a fixing ring groove 17 is provided on the top of the inner wall of the fixing screw hole 5. A limit snap ring 16 is arranged inside the fixing ring groove 17, and one end of the limit screw 14 is rotatably connected to the limit snap ring 16.
