Embodiment 1

[0020] In this embodiment, in order to cover the terminals connecting the cables inside the cabinet when needed, preferably, a sealing plate 114 is provided on the side of the front support rod 106 away from the rear support rod 108, so that The lower end of the sealing plate is fixedly connected to the lower end cover, so that the upper end surface of the sealing plate 114 is attached to the lower end surface of the instrument support plate 109 . After connecting the instrument, make the sealing plate cover the outside of the bracket, use the sealing plate to wrap the bracket inside the cabinet, the bracket and the terminal cannot be seen directly from the outside, so that the cables connected to the instrument are covered inside the cabinet, Therefore, it is not easy to have the problem of illegally connecting cables and causing electricity theft.

[0021] In this embodiment, in order to fix the sealing plate conveniently, it is further preferred that the lower end of the se...

Embodiment 2

[0023] In this embodiment, in order to facilitate the installation of meter equipment, preferably, the instrument support plate 109 is provided with a boss 115 for installing the instrument. After the instrument support plate is fixed on the slot, the upper end surface of the boss Relatively parallel to the lower end surface, it is convenient to install the meter. A through hole for fixing the meter is provided on the boss 115. The meter can be fixed on the boss with bolts, so that the wire passing hole 113 is located on the boss. The middle part of Taiwan 115 is convenient for connecting cables.

[0024] Further preferably, in this embodiment, an inverted T-shaped connecting rod 116 is arranged below the boss 115, so that the upper end of the connecting rod 116 is hinged on the lower end surface of the boss 115, so that The connecting rod can rotate relative to the lower end surface of the boss, and a connecting plate 117 is arranged on the bracket 111, so that the connecting...
