Detailed ways

The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

Example 1

As shown in Figures 1 and 2, an electric meter box with anti-oxidation function of fasteners includes a box body 1, a box door 2, a wiring window door 3, and a door handle 4 is installed on the outside of the wiring window door 3 by screws.

The box body 1 is fixedly connected to a support frame. The support frame is used to install the electric meter, the leakage protection switch and the terminal block 5. The long side of the support frame extends in the horizontal direction, as shown in Figures 3 and 4. The wing plates 7 on the upper and lower sides of the fixing plate 6, the rear end of the terminal block 5 is provided with an up-turning L-shaped hanging plate 8 and a lower-hanging L-shaped hanging plate 9, and the terminal block 5 passes through the upward-turning L-shaped hanging plate 8 and the lower-hanging L-shaped hanging plate 9. The hanging plate 9 is slidably connected with the wing plate 7 on the support frame. The wing plate 7 is provided with a plurality of waist holes 10. The leakage protection switch and the electric meter are fixed on the wing plate by bolts (not shown in the figure).

As shown in FIG. 2 , the rear side of the box body 1 is provided with a plurality of fastening screws 11 that are fixed to the wall. The tips of the fastening screws 11 protrude out of the box body 1. As shown in FIG. The fixing screw 11 is sleeved with a waterproof part that can be deformed by extrusion. The waterproof part that can be deformed by extrusion includes a frustum part 12 close to the wall and a deformation part 13 close to the box. The frustum part 12 has a smaller cross-section. One end is close to the wall, and the deformation portion 13 is a spindle-shaped structure with an increasing diameter from both ends to the middle along the axis direction.
