Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0021] See also Figure 1-Figure 3 , the utility model provides a technical solution: a dustproof and waterproof double sealing oil seal, comprising: an oil seal component 1, on which a dustproof component 2 is installed;

[0022] Among them, the dustproof component 2 includes a rotating ring 21, a connecting plate 22, cleaning bristles 23 and a clamping ring 24. The rotating ring 21 is installed on the oil seal component 1, the clamping ring 24 is installed on the rotating ring 21, the connecting plate 22 is installed on the clamping ring 24, and multiple cleaning bristles 23 are provided, and multiple cleaning bristles 23 are all installed on the connecting plate 22.

[0023] Specifically, in order to prevent external dust from entering the interior of the device through the connection gap between the oil seal assembly 1 and the device during use, a dustproof assembly 2 is provided on the oil seal assembly 1. During specific use, the dustproof assembly 2 can be rotated to protect the outer surface of the oil seal assembly 1, thereby preventing dust in the external air from entering the device.

[0024] Furthermore, during use, by installing a rotating ring 21 on the oil seal assembly 1, installing a clamping ring 24 on the rotating ring 21, installing a connecting plate 22 on the clamping ring 24, and installing a plurality of cleaning bristles 23 at the lower end of the connecting plate 22, the rotating ring 21 can be rotated to drive the connecting plate 22 to rotate, thereby driving the cleaning bristles 23 to clean the outer surface of the oil seal assembly 1 to prevent dust from entering the device.

[0025] like Figure 1-Figure 3 As shown, the oil seal assembly 1 includes an outer rubber ring 11 , a frame 12 and an inner rubber ring 13 . The outer rubber ring 11 and the inner rubber ring 13 are respectively installed on the inner and outer surfaces of the frame 12 , and the outer rubber ring 11 and the inner rubber ring 13 are tightly fitted to the frame 12 .

[0026] Specifically, during actual use, the outer rubber ring 11 and the inner rubber ring 13 arranged on the inner and outer surfaces of the skeleton 12 can prevent external liquid from entering the device through the connecting gap, and in order to improve the waterproof performance, the outer rubber ring 11 and the inner rubber ring 13 are tightly fitted to the skeleton 12.
