[0030] 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.

[0031] Reference Figures 1-4 An embodiment of this utility model provides a self-cleaning caster structure, including a mounting part 1. A caster frame 3 is fixedly connected to the bottom of the mounting part 1. A movable wheel 5 is installed on the inner side of the caster frame 3 by bolts 6. A connecting seat 1 8 is fixedly connected to the left and right sides of the front side of the caster frame 3. An adjusting rod 10 is rotatably connected to the inside of the connecting seat 1 8 by a positioning pin 9. A connecting seat 2 11 is rotatably connected to the other end of the adjusting rod 10 by a positioning pin 9. A connecting block 12 is fixedly connected to the bottom of the connecting seat 2 11. A connecting frame 13 is fixedly connected to the bottom of the connecting block 12. A cleaning cotton 16 is installed on the inner side of the connecting frame 13. The cleaning cotton 16 is attached to the outer front side of the movable wheel 5.

[0032] The upper part of the mounting part 1 is fixedly connected with a screw 4, and mounting holes 2 are opened at the four corners of the upper side of the mounting part 1; a nut 7 is externally threaded to one end of the bolt 6 to increase the tightness and firmness of the installation of the moving wheel 5; the length of the adjusting rod 10 can be adjusted to change the position of the cleaning cotton 16.

[0033] After screwing the screw 4 into the bottom of the device to be installed, insert the screw into the mounting hole 2 and screw it into the bottom of the device to complete the installation and fixation of the caster. When the device needs to be moved, as the caster 5 rotates, the cleaning cotton 16 that is in contact with it cleans the surface of the caster 5. When the position of the cleaning cotton 16 needs to be changed, pull the adjusting rod 10 to adjust it to the desired position, loosen the positioning pin 9 in the connecting seat 11 by half, then move the connecting frame 13 to adjust its angle so that it is completely in contact with the surface of the caster 5, and then tighten the positioning pin 9 again to fix the connecting frame 13 and the adjusting rod 10. This realizes the cleaning of the caster 5 and the flexible adjustment of the position and angle of the cleaning cotton 16, which improves the convenience of using the device and the cleaning and maintenance effect of the caster 5.

[0034] Reference Figures 4-7 The rear side of the connecting frame 13 has evenly distributed convex grooves 14. The outer side of the cleaning cotton 16 is fixedly connected with the same number of mounting blocks 17 as the convex grooves 14. The mounting blocks 17 are slidably connected inside the convex grooves 14. The upper and lower sides of the convex grooves 14 are fixedly connected with positioning components. The positioning components are used to ensure the firmness of the installation of the cleaning cotton 16. The positioning components include protrusions 15. The protrusions 15 are fixedly connected to the upper and lower sides of the inner wall of the convex grooves 14. The mounting blocks 17 have the same number of positioning holes 18 as the protrusions 15 on both sides. The protrusions 15 are engaged inside the positioning holes 18.

[0035] When the cleaning cotton 16 needs cleaning or replacement due to damage, remove the positioning pin 9 inside the connecting seat 11 to separate the connecting frame 13 from the adjusting rod 10. This facilitates the suction and replacement of the cleaning cotton 16, reducing the difficulty and time required for replacement. Then, pull the cleaning cotton 16 upwards forcefully, causing the mounting block 17 to slide inside the convex groove 14. As the mounting block 17 moves, the protrusion 15 separates from the positioning hole 18, eliminating the limitation on the mounting block 17 and completely separating the cleaning cotton 16 from the connecting frame 13. This reduces the difficulty and time required for replacing the cleaning cotton 16, and extends the life of the casters by cleaning their surfaces.

[0036] Working principle: When using this caster, after screwing the screw 4 into the bottom of the device to be installed, insert the screw into the mounting hole 2 and screw it into the bottom of the device to complete the installation and fixation of the caster. When the device needs to be moved, as the moving wheel 5 rotates, the cleaning cotton 16 that is in contact with it cleans the surface of the moving wheel 5. When the cleaning cotton 16 needs to be cleaned or is damaged and needs to be replaced, the connecting seat 11 is removed and separated from the adjusting rod 10. Then, the cleaning cotton 16 is pulled upward with force, so that the mounting block 17 slides inside the convex groove 14. At the same time, the protrusion 15 separates from the positioning hole 18, no longer limiting the mounting block 17, so that the cleaning cotton 16 is completely separated from the connecting frame 13 and removed.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
