[0008] and a visual sheet mounted on the inner wall of the mounting ring;

[0009] When the connection block is completely connected to the cover body, the mounting ring fits on the cover body, and the first sealing ring abuts against the cover body at one end and against the bottom of the first ring groove at the other end to form a seal.

[0010] By adopting the above technical solution, the visual sheet is first installed on the inner wall of the mounting ring, and then the first sealing ring is installed in the first ring groove. At this time, the cover body is connected to the engine crankcase body by bolts, and then a number of connecting blocks are installed on the cover body accordingly. When the connecting blocks are fully installed, one end of the first sealing ring abuts against the cover body, and the other end abuts against the bottom of the first ring groove, thereby achieving a sealing effect. At this time, the overall installation has been completed, and the operator can view the interior of the cover body and the engine crankcase body through the visual sheet. The height of the above-mentioned first sealing ring is slightly higher than the depth of the first ring groove. When it is fully connected through the connecting blocks, it is squeezed and abutted against the cover body and the bottom of the first ring groove.

[0011] Furthermore, a detachable sealing device for installing the visual sheet is provided on the inner wall of the mounting ring, and the detachable sealing device is used to install the visual sheet and prevent liquid from flowing out of the inner wall of the mounting ring.

[0012] Furthermore, the detachable sealing device comprises:
