[0017] The preferred embodiments of the utility model will be described in detail below with reference to the drawings. Example 1

[0018] like Figures 1 to 3 As shown, a connection structure of an oil tank 1 and a tank cover 2 is shown. The gear 10 of the transmission device is installed in the space formed by the oil tank 1 and the tank cover 2. The oil tank 1 has an oil tank opening 11 and an oil tank bottom 12. The edge of the oil tank opening 11 connected to the tank cover 1 is a first connecting portion 111. The first connecting portion 111 is connected to the tank cover 2 through a groove 13. The groove 13 is located on the inner side of the first connecting portion 111 and is arranged along the length direction of the first connecting portion 111. The groove 13 has a first groove wall 13 1 and a second groove wall 132. The first groove wall 131 is located on a side close to the first connecting portion 111. The top end 1311 of the first groove wall 131 is connected to the first connecting portion 111, and the bottom end 1312 of the first groove wall 131 is connected to the bottom end 1321 of the second groove wall 132. The connection between the first groove wall 131 and the second groove wall 132 forms a groove bottom 133. The groove bottom 133 is closer to the oil groove bottom 12 than the first connecting portion 111. The groove 13 is provided with an overflow port.

[0019] The tank cover 2 has a tank cover opening end 21 and a tank cover closed end 22. The edge of the tank cover opening end 21 connected to the oil tank opening 11 is a second connecting portion 211. The second connecting portion 211 is connected to the oil tank 1 through a plug-in portion 23. The plug-in portion 23 is located on the inner side of the second connecting portion 211 and is arranged along the length direction of the second connecting portion 211. The plug-in portion 23 has a first plug-in arm 231 and a second plug-in wall 232. The first plug-in arm 231 is laterally arranged on the inner side of the tank cover opening end 21. One end 2311 of the first plug-in arm 231 is connected to the second connecting portion 211, and the other end 2312 of the first plug-in arm 231 is connected to the second plug-in arm 232. The second plug-in arm 232 faces away from the closed end 22 of the slot cover. The length of the second plug-in arm 232 is limited to when the oil tank 1 is connected to the slot cover 2, the second plug-in arm 232 is embedded in the slot 13, and the first plug-in arm 231 is in contact with the first slot wall 131 and the first connecting portion 111.

[0020] In this embodiment, a through hole 134 is defined in the second groove wall 132. This through hole 134 forms the overflow port. The angle between the first groove wall 131 and the second groove wall 132 is limited to a gap a between the second plug arm 232 and the groove bottom 133 when the second plug arm 232 is inserted into the groove bottom 133. The through hole 134 extends horizontally through the gap a. During operation, oil splashed from the rotation of the transmission gear flows along the second plug arm 232 into the groove 13 and then flows back into the oil tank 1 through the through hole 134, thereby preventing accumulated oil from overflowing the open end of the oil tank. Example 2

[0021] like Figure 4 As shown, the difference between Example 2 and Example 1 is that the top 1322 of the second groove wall 132 is closer to the groove bottom 133 than the top 1311 of the first groove wall 131. The space above the top 1321 of the second groove wall 132 forms the overflow port. During operation, oil splashed from the rotation of the transmission gear flows along the second connecting arm 232 into the groove 13, then overflows back into the oil tank 1 through the space above the top 1322 of the second groove wall 132, thereby preventing accumulated oil from overflowing the open end of the oil tank.

[0022] The groove and the oil groove, the plug-in part and the groove cover of the utility model can all be obtained by integrally forming using a mold; the cross-sectional shape of the groove is not limited to V-shaped, but can also be U-shaped; compared with the overflow port structure of Example 2, the overflow port structure of Example 1 is horizontally connected with the gap, which can discharge the accumulated oil into the oil groove more promptly, and the overflow effect is better. The through hole can be opened on the first groove wall, or on the bottom of the groove, or on both the first groove wall and the second groove wall, among which it is easiest to open the through hole on the second groove wall; the shape of the plug-in part is not limited to the embodiment described, but can also be an inclined plate, as long as the plug-in part can be embedded in the groove when the oil groove and the groove cover are opposite to each other, to form a barrier to the splashing oil; when the shape of the plug-in part is similar to L-shaped, the size and shape of the plug-in part can be such that the second plug-in arm can be stuck in the groove when the oil groove and the groove cover are connected, and the first connecting part abuts against the first plug-in arm, or the first connecting part abuts against the second connecting part.

[0023] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
