Technical Field

[0001] The utility model relates to the technical field of accessories for power transmission and distribution equipment, and particularly relates to a wall bushing. Background Technique

[0002] Power transmission and distribution refer to power transmission, transformation, and distribution. Among them, power transmission refers to the transmission of electric energy. Through power transmission, power plants and load centers that are far apart (up to thousands of kilometers) are connected, enabling the development and utilization of electric energy to transcend geographical limitations; power transformation refers to the process of using certain equipment to transform the voltage from a low level to a high level (step-up) or from a high level to a low level. Power distribution is a means of distributing electric power to users within the area where electric energy is consumed. Wall bushings are usually required in the process of power transmission and distribution.

[0003] In the existing wall bushing, the outer sleeve and the flange are usually fixed by bolts, which increases the subsequent assembly process, reduces the convenience of using the wall bushing, and at the same time, the fixation between the outer sleeve and the flange by only bolts is not firm enough, resulting in poor structural strength of the outer sleeve and the flange and shortening the service life of the wall bushing; at the same time, the existing wall bushing is not convenient enough during assembly, thus increasing the labor intensity during the assembly of the wall bushing. Content of the Utility Model

[0004] The purpose of the utility model is to provide a wall bushing to solve the problems in the above background technique that the existing wall bushing is not firmly fixed by bolts and has a large labor intensity during assembly.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A wall bushing, including an outer sleeve, a flange is integrally cast at the central part of the surface of the outer sleeve. There are two rows of reinforcing ribs, upper and lower, between the outer sleeve and the flange. Each row has two reinforcing ribs. The two reinforcing ribs in the upper row are arranged on the upper surface of the flange and on the left and right sides of the outer sleeve, and the two reinforcing ribs in the lower row are arranged on the lower surface of the flange and on the left and right sides of the outer sleeve. At the same time, the reinforcing ribs and the outer sleeve and the flange are integrally cast. A hollow cavity is opened inside the outer sleeve, and an inner sleeve with both ends penetrating is inserted into the hollow cavity.

[0006] Preferably, a sealing groove is arranged at the edge position of the surface of the flange, and this sealing groove is used for the sealing work after the wall bushing is installed.

[0007] Preferably, the diameters of the upper and lower ends of the hollow cavity are both larger than the outer diameter of the inner sleeve to facilitate the insertion of the inner sleeve into the hollow cavity.

[0008] Preferably, connecting screw holes are arranged at both the upper and lower ends of the inner sleeve, and these connecting screw holes facilitate the connection work at both ends of the inner sleeve.

[0009] Preferably, mounting holes are provided on both the upper and lower surfaces of the flange, which facilitate the fixed installation of the wall-piercing casing.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: The wall-piercing casing integrally casts the outer sleeve and the flange, solving the problem of fixing with bolts in the prior art, reducing subsequent assembly processes, improving the convenience of using the wall-piercing casing. At the same time, two rows of reinforcing ribs are provided between the outer sleeve and the flange, and all four reinforcing ribs are integrally cast between the outer sleeve and the flange, increasing the structural strength of the outer sleeve and the flange and extending the service life of the wall-piercing casing. At the same time, by providing a hollow cavity inside the outer sleeve, and the diameters of both ends of the hollow cavity are larger than the outer diameter of the inner sleeve, this design facilitates the rapid insertion of the inner sleeve into the interior of the hollow cavity, improving the convenience during assembly, and thus reducing the labor intensity during the assembly of the wall-piercing casing.
