[0020] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.​

[0021] Example 1

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a cylinder housing for an oil-cooled motor, comprising a housing 1, the housing 1 being cylindrical, and an inwardly protruding retaining ring 21 provided on the inner wall of the housing 1. The retaining ring 21 blocks the end face of the sealing plug. The retaining ring 21 and the housing 1 are integrally formed. The sealing plug is inserted into the housing 1 through the retaining ring 21 by interference fit, thereby improving the installation efficiency of the sealing plug. The retaining ring 21 blocks the gap between the sealing plug and the housing 1, further enhancing the sealing performance between the sealing plug and the housing 1 and preventing internal oil leakage to the surface of the housing 1. An end plate 3 is formed on the other end of the housing 1, and an opening 4 is provided in the center of the end plate 3 for inserting the sealing plug inside the housing 1. The retaining ring 21 and the end plate 3 are located at both ends of the sealing plug, positioning both ends of the sealing plug and preventing the sealing plug from sliding out of the housing 1.

[0023] like Figure 3 As shown, a sealing ring groove 11 is provided on the inner wall of the housing 1. The sealing ring is embedded in the sealing ring groove 11, so that the sealing ring is set on the inner wall of the housing 1 and the surface of the sealing plug, thereby enhancing the sealing performance between the housing 1 and the sealing plug.

[0024] A first sealing ring 6 and a second sealing ring 7 are fitted onto the surface of the housing 1. The first sealing ring 6 and the second sealing ring 7 enhance the sealing between the housing 1 and the equipment, preventing the housing 1 from loosening inside the equipment after installation.

[0025] A connecting ear 5 is formed on the connecting part 2. The connecting ear 5 is embedded in the device. The end face of the housing 1 is flush with the end face of the device. A connecting hole is opened inside the connecting ear 5. Fasteners are connected inside the connecting ear 5 to fix the housing 1 to the device.

[0026] Opening 4 is a rectangular hole, and the shape of opening 4 corresponds to the number of wires coming out.

[0027] Example 2

[0028] like Figure 4 and 5 As shown, in another embodiment, the retaining ring 21 and the housing 1 are separate. A groove is provided on the inner diameter of the housing 1. The retaining ring 21 is connected to the groove by fasteners. The inner diameter of the groove is larger than the inner diameter of the housing 1, which makes it convenient to install the sealing plug. After the sealing plug is installed, the retaining ring 21 is connected to the housing 1 by bolts to limit the end of the sealing plug and fix the sealing plug, which facilitates the installation of the sealing plug.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
