DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0021] This embodiment provides a waterproof roller structure, including a frame 1, a sealing step sleeve 7, and a waterproof sealing ring 11. The frame 1 is used to mount the roller, and the sealing step sleeve 7 and the waterproof sealing ring 11 can prevent water or dust from entering the roller or other components.

[0022] like Figure 1-Figure 2 As shown, a flange 2 is provided on one side of the frame 1, and a rotating shaft 4 is connected to the inside of the flange 2 by a bearing 3; the frame 1 provides an installation space for the flange 2, and the rotating shaft 4 can rotate inside the flange 2;

[0023] A roller 5 is provided at one end of the rotating shaft 4, and a sprocket 6 is provided at the other end of the rotating shaft 4. The roller 5 is used for logistics transportation. The sprocket 6 is combined with an external chain to drive the roller 5 to rotate;

[0024] An inwardly contracted limiting ring 9 is provided at one end of the inner hole 8 of the flange 2, and a sealing step sleeve 7 is clamped between the limiting ring 9 and the rotating shaft 4. The sealing step sleeve 7 can prevent water or dust from entering the interior of the flange 2 to avoid corrosion of the transmission components;

[0025] A skeleton sealing ring 10 is provided between one side of the sealing step sleeve 7 and the bearing 3. The skeleton sealing ring 10 and the sealing step sleeve 7 form a double sealing structure, and the skeleton sealing ring 10 can limit the sealing step sleeve 7.

[0026] A sealing groove 12 is provided on the side wall where the flange 2 contacts the frame 1 , and the waterproof sealing ring 11 is embedded in the sealing groove 12 . The waterproof sealing ring 11 can prevent water or dust from entering the frame 1 , thereby preventing the transmission components inside the frame 1 from being corroded and damaged.

[0027] Furthermore, the flange 2 and the frame 1 are fixedly connected by a connecting piece 13 , which is a connecting bolt, so that the frame 1 and the flange 2 can be quickly assembled and disassembled.

[0028] Furthermore, a spacer sleeve 14 is provided between the bearing 3 and the sprocket 6, and an end retaining ring 15 for fixing the sprocket 6 is provided at one end of the rotating shaft 4. The spacer sleeve 14 plays an axial limiting role in fixing the bearing 3 and the sprocket 6, and the end retaining ring 15 is used to limit the axial displacement of the sprocket 6.

[0029] Furthermore, a fixing groove 16 is opened at one end of the inner hole 8 of the flange 2, and a hole retaining ring 17 for fixing the bearing 3 is set in the fixing groove 16. The hole retaining ring 17 and the spacer 16 fix the bearing 3 at the same time. The bearing 3 is two deep groove ball bearings.

[0030] Furthermore, a connecting plate 18 is provided at the end of the rotating shaft 4, and one end of the roller 5 is sleeved on the connecting plate 18 and fixed by welding. The welding fixation makes the roller 5 sealed and water cannot enter the inside of the roller.
