In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0022] As Figures 1 - 3It is a schematic structural diagram of a wall bushing in a preferred embodiment of the present utility model. In this embodiment, a wall bushing includes a connecting bushing 1 and porcelain bushings 2 installed at both ends of the connecting bushing 1. The connecting bushing 1 includes a connecting seat 3 and a connecting flange 4. One end of the connecting seat 3 is provided with a connecting flange 4, and the connecting flange 4 is sleeved on the surface of one of the porcelain bushings 2. The connecting seat 3 is arranged between the joints of the two porcelain bushings 2. Combining the structural design of the present utility model, by setting the connecting seat 3, the function of assembling and connecting the two porcelain bushings 2 can be achieved, effectively solving the problem that when one of the porcelain bushings 2 is damaged during use, only the damaged porcelain bushing 2 needs to be replaced, thereby reducing the use cost and having better practicability.
