[0024] Example 1

[0025] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a deep groove ball bearing with a dustproof structure, comprising: a dustproof mechanism 1, the inner wall of the dustproof mechanism 1 is provided with a heat dissipation mechanism 2, the dustproof mechanism 1 comprises an outer ring 11, a dustproof ring 12 is provided inside the outer ring 11, the inner side of the outer ring 11 is movably contacted with the outer side of the dustproof ring 12, an inner ring 17 is provided on the inner side of the dustproof ring 12, the inner side of the dustproof ring 12 is fixedly connected to the outer side of the inner ring 17, and the top side of the dustproof ring 12 is provided with The top side of the cleaning cotton 15 and the dustproof ring 12 are fitted with the bottom side of the cleaning cotton 15. The inner wall of the cleaning cotton 15 is provided with a horizontal plate 13. The inner wall of the cleaning cotton 15 fits with one end of the bottom side of the horizontal plate 13. One end of the horizontal plate 13 is movably connected to the top side of the outer ring 11. The inner wall of the bottom side of the horizontal plate 13 is provided with a rubber ring 14. The inner wall of the bottom side of the horizontal plate 13 is fixedly connected to the outer side of the rubber ring 14. The inner side of the rubber ring 14 is provided with an insertion rod 16. The inner side of the rubber ring 14 is connected to the insertion rod 16. The outer side of one end of the rod 16 fits tightly, one end of the insertion rod 16 is connected to the inner wall of the cleaning cotton 15, one end of the insertion rod 16 is connected to the inner wall of the bottom end of the horizontal plate 13, the top of the inner ring 17 is provided with a magnet 18, the top of the inner ring 17 is fixedly connected to the bottom side of the magnet 18, the top side of the magnet 18 is adsorbed and connected to one end of the horizontal plate 13, the inner wall of the dust ring 12 is movably connected to one end of the closing plate 19, and the inner wall of the closing plate 19 is provided with an inner plate 110, which is closed. The inner wall of plate 19 is slidably engaged with one end of inner plate 110, a movable plate 111 is provided at one end of the top side of inner plate 110, one end of the top side of inner plate 110 is fixedly connected with the bottom side of movable plate 111, the bottom side of movable plate 111 contacts the top side of dustproof ring 12, a fixing part 112 is provided on the inner wall of movable plate 111, the inner wall of movable plate 111 is threadedly connected with the outer side of fixing part 112, and the outer side of one end of fixing part 112 is threadedly connected with the inner wall of dustproof ring 12.

[0026] In this embodiment, when the deep groove ball bearing with a dust-proof structure is in use, first, a dust ring 12 is installed between the outer ring 11 and the inner ring 17, and the dust ring 12 is connected to the inner side of the inner ring 17. The existence of the dust ring 12 can prevent dust from entering the bearing from the gap at the connection as much as possible. After the inner ring 17 is connected to the shaft, the cross plate 13 is toggled so that one end of it is adsorbed by the magnet 18 on the inner ring 17. At the same time, a cleaning cotton 15 is installed on the cross plate 13. After being toggled, the cleaning cotton 15 will naturally contact the dust ring 12. When the inner ring 17 rotates, the cleaning cotton 15 will automatically wipe the dust on the dust ring 12. This friction can effectively remove dust and dirt accumulated on the dust ring 12, keep the dust ring 12 clean, and after the dirt on the dust ring 12 is removed, the risk of dust and pollutants entering the bearing through the gap can be further reduced.

[0027] Secondly, after a period of use, the cleaning cotton 15 can be released by pulling the insertion rod 16 out from the inner wall of the horizontal plate 13, thereby releasing the restriction on the cleaning cotton 15, and then replacing the original cleaning cotton 15. The newly replaced cleaning cotton 15 can more effectively remove dust and dirt on the dust ring 12, thereby improving the working efficiency of the entire bearing and its protective structure, ensuring smoother operation.

[0028] In addition, by pushing the movable plate 111, the inner plate 110 is separated from the closing plate 19. At this time, the closing plate 19 is detent to open its filling channel, and then lubricating grease can be added to the bearing. Regular filling of lubricating grease can prevent damage to the bearing caused by dry friction, protect the integrity of the bearing components, and reduce the occurrence of failures.

[0029] Example 2

[0030] like Figure 1 As shown, the heat dissipation mechanism 2 includes a fixed plate 21, the inner wall of the fixed plate 21 is provided with a connecting rod 22, the inner wall of the fixed plate 21 is fixedly connected to one end of the connecting rod 22, and the outer side of the fixed plate 21 is provided with a closing plate 19, and the outer side of the fixed plate 21 fits with the inner wall of the closing plate 19.

[0031] In this embodiment, a fixing plate 21 is installed in the inner wall of the closing plate 19. Therefore, by detent the connecting rod 22, the fixing plate 21 is disengaged from the closing plate 19. This can increase the heat dissipation area of the bearing and release heat more effectively, thereby reducing the temperature of the bearing and preventing overheating. Excessive temperature will cause thermal expansion of the material, which may cause deformation or failure of the bearing. Timely heat dissipation helps to control the temperature, thereby preventing structural problems caused by thermal expansion.
