[0009] According to the above technical scheme, the inner wall of the box is provided with a dehumidification device for adsorbing moisture, and the inner wall of the box is provided with a protective device. The dehumidification device includes a mesh frame, a connecting rod, a gear, a connecting plate, a displacement hole, a T-shaped rod and an L-shaped plate. The rotation of the connecting rod drives the connecting plate to rotate, and the rotation of the connecting plate breaks up and stirs the activated carbon inside the mesh frame.

The sponge block is deformed by the squeezing of the pressing plate and squeezes out the condensed water absorbed by itself. The liquid squeezed out of the sponge block is discharged through the drain pipe under the action of its own gravity. The collecting frame is fixedly installed on the inner wall of the box, the sealing frame is fixedly penetrated through the inner and outer walls of the box, the sealing rod is fixedly installed on the inner wall of the sealing frame, the pressing plate is slidably installed on the circumferential surface of the sealing rod, the connecting pipe is arranged between the collecting frame and the sealing frame, the sponge block is arranged on the inner wall of the sealing frame, the drain pipe is fixedly installed at the bottom of the sealing frame, and the heat dissipation hole is opened on the left side of the box. By discharging condensed water, it helps to maintain a dry environment of the box and reduce the failure rate caused by moisture. By effectively preventing the splashing of condensed water, the chance of electrical equipment being exposed to a humid environment can be reduced, and the risk of leakage can be reduced.

[0013] According to the above technical solution, a No. 5 spring is arranged between the pressing plate and the sealing frame, and the No. 5 spring can drive the pressing plate to reset.

A groove is opened on the right side of the sealing frame.

[0014] The present invention provides an electric meter box with an anti-theft function. It has the following beneficial effects: The electric meter box with an anti-theft function moves the fixing frame toward the rear side to disengage from the limit groove and release the limit on the anti-theft door. The limit of the fixing frame can prevent the anti-theft door from being easily opened due to prying, thereby improving the safety of the box and reducing the occurrence of illegal acts such as electricity theft. The protective plate moves toward the direction close to the T-shaped plate and cooperates with the T-shaped plate to limit and fix the connecting wire, thereby preventing the connecting wire from being pulled at will.

(2) The electric meter box with anti-theft function breaks up and stirs the activated carbon inside the mesh frame by rotating the connecting plate. The agglomerated activated carbon particles are loosened by the stirring of the connecting plate, thereby improving the adsorption effect of moisture inside the box. The stirring of the connecting plate loosens the activated carbon particles, increasing the gaps between the particles, thereby expanding the surface area, thereby reducing the risk of moisture corrosion to the electric meter and extending the service life of the electric meter.

[0015] (3) The electric meter box with anti-theft function can manually push the free end of the elastic telescopic rod to move away from the T-shaped rod to release the limit on the L-shaped plate. The elastic telescopic rod prevents leakage of activated carbon particles caused by accidental external force, which can effectively protect the electrical components in the box from being contaminated or damaged by the activated carbon particles. The L-shaped plate moves to the right to break away from the contact with the replacement hole and release the seal on the mesh frame. The activated carbon is replaced in time after it is saturated with adsorption, which can ensure that the moisture adsorption effect inside the electric meter box is always in the best state, further preventing moisture from affecting the performance of electrical equipment.

[0016] (4) The electric meter box with anti-theft function is deformed by the sponge block being squeezed by the pressing plate and the condensed water absorbed by itself is squeezed out and discharged. By discharging the condensed water, it helps to maintain a dry environment of the box and reduce the failure rate caused by moisture. The dripping condensed water is blocked and collected by the collection frame to prevent the condensed water from falling directly into the box. By effectively preventing the splashing of condensed water, the chance of electrical equipment being exposed to a humid environment can be reduced, thereby reducing the risk of leakage.
