[0024] 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.

[0025] This utility model provides, for example Figure 2-7 The roller assembly shown includes a rubber wheel rim 1, a hub 2 for mounting the rubber wheel rim 1 is provided inside the rubber wheel rim 1, a roller for connecting a micro switch and a roller encoder is inserted inside the hub 2, a locking block 6 for connecting with the hub 2 is provided outside the roller, and a mounting groove 8 for inserting the locking block 6 is provided on one side of the hub 2, and a plug 7 for preventing the mounting groove 8 from moving is provided inside the mounting groove 8;

[0026] The roller assembly includes an insert shaft 3, and a locking block 6 is disposed on the outer wall of the insert shaft 3;

[0027] The tamping element 7 includes a tamping block 71, which is inserted inside the mounting groove 8 and is used to restrict the movement of the mounting groove 8.

[0028] Specifically, a circular through groove is provided on one side of the hub 2, and the through shaft 3 is inserted into the circular through groove. The two ends of the through shaft 3 are respectively fixedly connected to the pressing shaft 4 and the encoding shaft 5. The pressing shaft 4 is used to press down the micro switch, and the encoding shaft 5 is used to be inserted into the inside of the roller encoder.

[0029] Furthermore, the rubber wheel rim 1 is fitted onto the outer wall of the hub 2, and the diameter of the circular through groove of the hub 2 matches the diameter of the through shaft 3. The pressure shaft 4, the through shaft 3, and the coding shaft 5 are cast as a single piece, and their shape and specifications are the same as those of the existing roller shaft. The materials and dimensions of the rubber wheel rim 1 and the hub 2 are the same as those of the existing roller.

[0030] Specifically, a threaded groove is provided on one side of the filling block 71, and a fixing bolt 72 is threadedly connected inside the threaded groove. A threaded groove 9 is provided on one side of the inner wall of the mounting groove 8, and one end of the fixing bolt 72 is threadedly connected to the threaded groove 9. One end of the locking block 6 is fixedly connected to the outer wall of the insertion shaft 3. The mounting groove 8 is opened on one side of the insertion shaft 3, and the locking block 6 is slidably connected to the mounting groove 8. The mounting groove 8 is an L-shaped groove.

[0031] Furthermore, three locking blocks 6 are provided, arranged in an evenly spaced ring on the outer wall of the through shaft 3. The locking blocks 6 and the through shaft 3 are manufactured by integral casting. The material of the locking blocks 6 is the same as that of the through shaft 3. The number of mounting slots 8 corresponds to the number of locking blocks 6, and the width of the mounting slots 8 corresponds to the width of the locking blocks 6. A threaded groove 9 is formed inside one of the mounting slots 8. The filling block 71 and the locking blocks 6 can fill the horizontal groove of the mounting slot 8 parallel to the hub 2. The filling block 71 and the locking blocks 6 each occupy half of the volume of the horizontal groove of the mounting slot 8. The threads on the inner wall of the threaded groove 9 and the threads on the inner wall of the threaded through groove are connected to the fixing thread. The threads on the outer wall of bolt 72 mesh with each other. When the encoder shaft 5 or the pressing shaft 4 is damaged, affecting the subsequent use of the rolling wheel, the fixing bolt 72 is rotated counterclockwise to move the end of the fixing bolt 72 out of the threaded groove 9. At this time, the filling block 71 is moved out of the mounting groove 8. When the filling block 71 is moved out, the compression on the locking block 6 is released, so the through shaft 3 can be rotated to move the locking block 6 to the horizontal groove position of the mounting groove 8 perpendicular to the hub 2. This allows the through shaft 3 to move away from the hub 2, so that the roller component can be replaced without replacing the rubber wheel rim 1 and the hub 2, thus saving resources.
