[0043] During use, when it is necessary to place the placement plate 7 into the storage groove 4, first press the pressing block 19 downward to move the pressing block 19 down along the vertical rod 17, and then the placement plate 7 can be stored in the storage groove 4, and the pressing block 19 can be released so that the pressing block 19 can be reset by the elastic force of the positioning spring 18 so that the limiting tube 21 arranged on the surface of the pressing block 19 is inserted into the limiting groove 15 opened on the side of the storage groove 4, so that the placement plate 7 can be fixed in the storage groove 4 by utilizing the limiting tube 21 in cooperation with the engagement of the limiting groove 15. The setting of the vertical rod 17 can guide the movement of the pressing block 19 on the one hand, and on the other hand, it can also avoid the problem of displacement of the positioning spring 18 when being compressed, thereby improving the stability of the positioning of the limiting tube 21.

[0044] To further improve the rain-proof effect, an extension plate 25 is provided. A groove 22 is formed on the side of the placement plate 7. A fixing plate 23 is arranged on the surface of the groove 22. The fixing plate 23 is in the shape of a square plate. There are two groups of fixing plates 23, and the two groups of fixing plates 23 are symmetrically distributed up and down with respect to the groove 22. A damping strip 24 is arranged on the end face of the fixing plate 23. The damping strip 24 is adhesively fixed on the surface of the fixing plate 23. An extension plate 25 is arranged in the groove 22. One end of the extension plate 25 is provided with a baffle 26. The extension plate 25 is in the shape of a "C"-shaped plate as a whole.

[0045] During use, after the rain-proof cover 8 is unfolded by using the placement plate 7, the extension plate 25 can be pulled out of the groove 22 through the traction buckle 27, so as to cooperate with the rain-proof cover 8 to increase the rain shielding range. The baffle 26 and the fixing plate 23 are arranged to prevent the extension plate 25 from detaching from the groove 22. When not in use, the extension plate 25 can be pushed into the groove 22 to fill the groove 22 by itself. The setting of the damping strip 24 can increase the friction force with the surface of the extension plate 25, prevent the extension plate 25 from sliding out of the groove 22 without external force, and improve the stability of the extension plate 25 in the groove 22.

[0046] During actual use, a storage groove 4 is formed on the side of the distribution box body 1, and a placement plate 7 is arranged in the storage groove 4.

Then, the placement plate 7 can be rotated through the limit bearing 6 to unfold the rain-proof cover 8, so that the rain-proof cover 8 can cover the heat dissipation openings 2 formed on the side of the distribution box body 1 to protect against external rain. An activated carbon plate 3 arranged in the heat dissipation opening 2 can adsorb the moisture entering from the heat dissipation opening 2. The overall design avoids the problem that because the distribution box body 1 is often placed outdoors and is often exposed to sun, rain and cold currents, when it rains, the splashing water droplets and the water vapor in the air may cause moisture or rain to enter the distribution box body 1 through the heat dissipation openings 2 and adhere to the electronic components, resulting in damage to the electronic components.

[0047] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
