[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a technical solution: a PU roller skating device, including a roller skate cover 1, a pulley frame 2 at the bottom of the roller skate cover 1, a roller 3 rotatably connected to the inner bottom end of the pulley frame 2, a connecting component between the roller skate cover 1 and the pulley frame 2, the connecting component including a mounting block 4 fixed to the bottom end of the roller skate cover 1, a U-shaped frame 5 fixedly connected to the outer side of the bottom end of the mounting block 4, a U-shaped groove 6 adapted to the U-shaped frame 5 at the top end of the pulley frame 2, a positioning post 7 at the top end of the pulley frame 2, and a positioning groove 8 adapted to the positioning post 7 at the bottom end of the mounting block 4, and the mounting... A threaded rod 9 is provided on the middle surface of the bottom end of block 4. A hole 11 adapted to the threaded rod 9 is opened on the top surface of pulley frame 2. A first nut 10 is threaded onto the surface of the threaded rod 9, and a second nut 12 is provided at the bottom of the first nut 10. The second nut 12 is threaded onto the surface of the threaded rod 9. After the first nut 10 is tightened onto the surface of the threaded rod 9, the second nut 12 is tightened onto the surface of the threaded rod 9, so that the first nut 10 can be firmly fixed in the designated position and will not easily loosen. The loop frame 5 and the positioning post 7 are both made of aluminum alloy, so that the pulley frame 2 and the After the mounting block 4 is connected, the stability is better. When it is necessary to connect the roller skate cover 1 to the pulley frame 2, first place the roller skate cover 1 in the designated position so that the roller skate cover 1 drives the mounting block 4 above the pulley frame 2, so that the loop frame 5 is inside the loop groove 6. At this time, the positioning pin 7 is also inserted into the positioning groove 8, and the threaded rod 9 passes through the hole 11. Then, the first nut 10 is tightened on the surface of the threaded rod 9, thus completing the connection operation between the roller skate cover 1 and the pulley frame 2. In the past, when connecting the roller skate cover 1 and the pulley frame 2, the roller skate cover 1 and the pulley frame 2 were directly connected by a screw. The traditional single-screw connection is not very secure. When the roller skates are in use, all the force is applied to the screw, which can easily cause it to loosen and make it easy for the roller skate cover 1 to detach from the roller frame 2. By designing the roller skate cover 1, roller frame 2, roller 3, and connecting components, the connection between the roller skate cover 1 and roller frame 2 is much more secure and durable than the traditional single-screw connection. This prevents the roller skate cover 1 from easily detaching from the roller frame 2, increases the overall sturdiness of the roller skate, and has a compact structure, making it worthy of promotion.

The output end of the synchronous motor 16 is coaxially fixedly connected to the end of the first rotating rod 14. The first rotating rod 14 and the second rotating rod 15 are the same size, and the cleaning box 13 is made of plastic, so that the roller 3 contacts the first rotating rod 14 and... When the second rotating rod 15 is in use, it provides better support for the roller 3. By designing an auxiliary mechanism, when the surface of the roller 3 of the roller skate is dirty, the operator can inject an appropriate amount of water into the cleaning box 13, and then place the roller skate inside the cleaning box 13 so that the roller 3 contacts the surfaces of the first rotating rod 14 and the second rotating rod 15. Then, the operator can turn on the synchronous motor 16, which will drive the first rotating rod 14 to rotate. When the first rotating rod 14 rotates, it will drive the roller 3 to rotate, thereby cleaning the dirt on the surface of the roller 3 and making it easier for the operator to clean the roller skate.
