[0023] Example 1: Figure 1 - Figure 4 As shown, the utility model provides a motor end cover that is easy to maintain, including an end cover mechanism 1, the outer side wall of the end cover mechanism 1 is fixedly connected to the fixing mechanism 2, the end cover mechanism 1 includes a cover plate 11, an outer rib plate 12 and a fixing block 13, the fixing block 13 passes through and is connected to the center of the outer wall of the cover plate 11, the outer rib plate 12 is fixedly connected between the fixing block 13 and the outer wall of the cover plate 11, a card slot 131 is provided on the outer wall of the fixing block 13, the inner wall of the fixing block 13 is movably connected to the dustproof plate 14, the outer wall of the dustproof plate 14 is fixedly connected to the card plate 15, the card plate 15 is clamped on the inner wall of the card slot 131, the inner wall of the fixing block 13 is threadedly connected to the outer sleeve mechanism 5, the outer sleeve mechanism 5 is arranged on the back of the cover plate 11, and the inner wall of the outer sleeve mechanism 5 is installed with a bearing 4.
[0024] The following is a detailed description of the specific settings and functions of this embodiment. By pushing the edge of the card plate 15 outward to separate it from the card slot 131, the dustproof plate 14 is driven to separate from the fixed block 13, exposing the bearing 4 from the outside, so that the user can directly perform grease lubrication maintenance on the bearing 4 from the outside of the end cover mechanism 1, avoiding the need to open the cover, and improving the maintenance convenience of the utility model. After maintenance, the card plate 15 and the card slot 131 are quickly connected and fixed, and the dustproof plate 14 can be used to provide external protection for the bearing 4 to prevent external foreign matter from entering.
[0025] Example 2: Figure 1 - Figure 4As shown, the fixing mechanism 2 includes a mounting block 21 and a mounting hole 22. The mounting block 21 is provided with three mounting holes 22. The mounting holes 22 are opened through the outer wall of the mounting block 21. The inner wall of the cover plate 11 is fixedly connected with the inner rib 16. The outer wall of the cover plate 11 is installed with a sealing ring 3. The outer sleeve mechanism 5 includes an externally threaded sleeve 51, a fixed dial plate 52 and a mounting groove 53. The mounting groove 53 is opened through the center of the outer wall of the externally threaded sleeve 51. The bearing 4 is installed on the inner wall of the mounting groove 53.
