[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1-Figure 4 The utility model provides an embodiment: a novel waterproof and dustproof caster, comprising a base plate 1, a triangular plate 2 is fixedly connected to the base plate 1, a rotating shaft 3 is passed through and rotatably connected to the triangular plate 2, a roller 4 is passed through and fixedly connected to the rotating shaft 3, a gear 5 is passed through and fixedly connected to the rotating shaft 3, a gear 2 6 is meshingly connected to the gear 15, a brush 7 is provided on the gear 15 and the gear 26, a rotating shaft 2 8 is passed through and fixedly connected to the gear 26, the rotating shaft 28 is passed through and rotatably connected to the triangular plate 2, the rotation of the roller 4 can drive the gear 15 to rotate, the rotation of the gear 15 can drive the gear 2 6 to rotate, the rotation of the gear 26 drives the brushes 7 on both sides to clean the roller 4 and the triangular plate 2, therefore, through such a setting, dust can be prevented from accumulating on the caster, thereby increasing the dustproofness of the caster.

[0028] The bottom plate 1 is fixedly connected with an oil storage tank 9, and an oil filling port 10 is fixedly connected to the oil storage tank 9, and an oil outlet pipe 11 is fixedly connected to the oil storage tank 9, and an oil pump 12 is arranged on the oil outlet pipe 11, and a mounting plate 13 is fixedly connected to the oil storage tank 9, and mounting holes 14 are arranged on the mounting plate 13, and the mounting holes 14 are arranged in four groups, and the four groups of mounting holes 14 are evenly distributed on the mounting plate 13, and the material of the roller 4 includes a waterproof layer 15, a waterproof layer 2 16, and a waterproof layer 3 17, and the waterproof layer 1 1 5. The waterproof layer 16 and the waterproof layer 17 are arranged in sequence on the roller 4. The materials of the waterproof layer 15, the waterproof layer 16 and the waterproof layer 17 are mainly acrylic emulsion, silicate and nanoparticles. By providing the waterproof layer 15, the waterproof layer 16 and the waterproof layer 17, they all have good waterproof properties, thereby enhancing the waterproof property of the caster. By providing the oil storage tank 9, the lubricity between the roller 4 and the rotating shaft 3 can be increased, thereby ensuring the service life of the roller 4.

[0029] Working principle: first, when the roller 4 rotates, the shaft 3 can drive the gear 5 to rotate, and the rotation of the gear 5 drives the gear 2 6 to rotate. The rotation of the gear 15 and the gear 2 6 can drive the brush 7 to clean the roller 4 and the triangle plate 2. Therefore, such a configuration can prevent dust from accumulating on the caster and increase the dustproofness of the caster. The waterproof layer 15, the waterproof layer 2 16 and the waterproof layer 3 17 are provided, and they all have good waterproofness, thereby enhancing the waterproofness of the caster. When there is a lack of lubrication between the roller 4 and the shaft 3, the oil pump 12 can be started. The oil pump 12 can draw the lubricant in the oil storage tank 9 into the oil outlet pipe 11, and then flow from the oil outlet pipe 11 into the space between the shaft 3 and the roller 4. In this way, the lubrication between the roller 4 and the shaft 3 can be increased, thereby ensuring the service life of the roller 4.
