[0046] The utility model uses when:
[0047] The installation steps are as follows: the bottom of the rotating shaft 122 welded at the inner side of the positioning frame 12 is passed through the opening at the rear end of the upper end surface of the mounting frame 11, so that the positioning frame 12 is mounted on the mounting frame 11. Then, the nut 123 is screwed on the second screw rod 1221, and the nut 123 is tightened to fix the positioning frame 12 and ensure that it is stably mounted on the mounting frame 11. The scraping frame 22 is movably clamped on the outer side of the wheel body 21, and the inner wall of the scraping frame 22 is in contact with the inner wall of the wheel body 21 but is not fixedly connected. At this time, the positioning bolt 23 is not installed. The assembled wheel body 2 and the scraping frame 22 are placed on the inner side of the mounting frame 11, so that the rear end of the scraping frame 22 is inserted into the reserved groove 111 at the bottom of the inner wall of the mounting frame 11, and the reserved groove 111 is matched with the rear end of the scraping frame 22. The positioning bolt 23 is passed through the wheel body 21 and the scraping frame 22, and the two ends of the positioning bolt 23 are passed through the reserved groove 111 on the mounting frame 11, respectively, and then the positioning bolt 23 is fixed, and the installation of the wheel body 2 and the scraping frame 22 is completed. The brake wrench 13 is rotatably installed in the slot at the front end of the upper end surface of the mounting frame 11, so that the brake wrench 13 can freely rotate along the slot at the front end of the upper end surface of the mounting frame 11.
[0048] The daily use steps are as follows: the luggage equipped with the wheel is pushed or pulled, and the wheel body 21 in the wheel body 2 rolls on the ground, driving the luggage to move. In the rotating process of the wheel body 21, the scraping frame 22 can scrape the sundries stuck in the gap of the wheel body 21 due to the contact between the scraping frame 22 and the inner wall of the wheel body 21, preventing the sundries from affecting the normal rotation of the wheel. At the same time, the scraping frame 22 is integrally formed by using stainless steel material, and has good durability and stability. When the luggage needs to be braked, the brake wrench 13 is rotated, so that the lower end surface of the brake wrench 13 is in contact with the upper front end of the wheel body 21. Since the lower end surface of the brake wrench 13 is provided with transverse anti-skid lines, the friction between the brake wrench 13 and the wheel body 21 is increased, thereby preventing the rotation of the wheel body 21 and achieving the brake function.
[0049] The disassembly steps are as follows: the connection structure between the brake wrench 13 and the slot at the front end of the upper end surface of the mounting frame 11 is released, and the brake wrench 13 is removed from the mounting frame 11. The positioning bolt 23 is unscrewed. The rear end of the scraping frame 22 is taken out of the reserved groove 111 at the bottom of the inner wall of the mounting frame 11, and then the assembled wheel body 2 and the scraping frame 22 are taken out from the inner side of the mounting frame 11. The scraping frame 22 is taken off from the outer side of the wheel body 21, and the separation of the wheel body 2 and the scraping frame 22 is realized. The nut 123 is unscrewed, and the positioning frame 12 is taken off from the mounting frame 11, and the disassembly of the positioning frame 12 is completed.
[0050] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
