[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example: See Figure 1-5 This utility model discloses a waterproof outdoor distribution box, including a distribution box 4. Each of the four corners of the bottom of the distribution box 4 is fixedly connected to a support post 5, which provides support for the distribution box 4. The distribution box 4 is covered by an outer casing 1, which reduces the corrosion and damage to the internal electrical equipment caused by external factors. The lower sides of the outer casing 1 have mounting openings with ventilation components 6 inside. The top of the outer casing 1 has a cover 10, which provides shielding and protection. The edge of the cover 10 has a guide groove. The front end of the outer casing 1 is hinged to a closed door 2, which allows operators to easily access the internal electrical equipment of the distribution box 4. Connecting plates 3 are horizontally fixed to the upper and lower ends and the middle of the rear end of the outer casing 1.

[0021] In this invention, the ventilation assembly 6 includes a dehumidifier box 13 located at the outer end of the mounting port and a baffle plate 12 located inside the opening of the dehumidifier box 13. Multiple air inlets 14 are equidistantly spaced on the lower outer side of the dehumidifier box 13, and multiple elliptical ventilation holes 11 are equidistantly spaced on the upper inner side of the baffle plate 12. The dehumidifier box 13 facilitates the absorption of moisture from the air entering the ventilation assembly 6, thus achieving dehumidification. A drain groove 7 is provided at the bottom of the dehumidifier box 13, and a drain pipe 9 is horizontally installed at the lower part of the drain groove 7, extending outwards from the outside of the dehumidifier box 13. A mounting strip protrudes from the outer bottom of the dehumidifier box 13, and a snap-fit ​​groove is provided on the bottom inner surface of the mounting port to fit the mounting strip. Multiple bolts 15 are equidistantly inserted into the strip, and threaded grooves are provided on the inner wall of the snap-fit ​​groove to accommodate the bolts 15. The bolts 15 facilitate the installation and disassembly of the ventilation component 6. Fixing holes 8 are provided at both ends of the connecting plate 3. The distribution box 4 is securely installed on the outdoor wall through the fixing holes 8 on both sides and the bolts 15. A waterproof sealing strip is provided on the outer shell of the distribution box 4. The waterproof sealing strip is installed on the edge where the distribution box 4 contacts the outer box 1, which facilitates a tight fit with the outer box 1. A sealing gasket is installed on the inner side of the closed door 2, and a waterproof handle is installed in the middle of the closed door 2. The sealing gasket enhances the sealing performance and improves the waterproof effect of the distribution box 4.

[0022] Working principle: When using this utility model, the cover 10 is located on top of the outer casing 1. The guide groove on its edge is the first line of defense against water. The cover 10 first prevents rainwater from falling directly onto the outer casing 1. Then, when the sealing door 2 is closed, the sealing gasket can effectively prevent rainwater from entering the distribution box 4 from the door gap, forming a second waterproof barrier. At the same time, the outer casing of the distribution box 4 is equipped with a waterproof sealing strip, which is installed at the edge where it contacts the outer casing 1. The sealing strip plays a key role in filling and sealing, preventing water droplets from accumulating. Next, the ventilation component 6 is... The waterproof and ventilation functions of the distribution box 4 are an important part of its design. The dehumidification box 13 and the baffle plate 12 play a dual role in waterproofing and ventilation. The size and position of the ventilation hole 11 are offset from the position of the air inlet 14. This ensures ventilation while effectively preventing large debris or raindrops from entering the distribution box 4 directly through the ventilation hole 11. Water entering the dehumidification box 13 through the air inlet 14 will be automatically discharged through the drainage groove 7 and the drainage pipe 9, avoiding water accumulation in the dehumidification box 13 or the outer casing 1.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
