[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] An outdoor ring network box with a waterproof structure, such as Figures 1-5 As shown, the device includes a frame 1, a bottom frame 6 fixed to the lower end of the frame 1, and a box top 3 fixed to the upper end of the frame 1. The upper end of the box top 3 is sloping to facilitate rainwater drainage. An upper opening 17 is provided on the box top 3. A box door 2 is rotatably installed on the side of the frame 1 and is sealed to the frame 1. A slot 18 is provided on the bottom frame 6 to connect the interior of the frame 1 and the bottom of the bottom frame 6. A heat dissipation frame 8 is fixed to the side of the bottom frame 6. A lower opening 11 is provided at the upper end of the heat dissipation frame 8. A ventilation opening 10 is provided between the bottom frame 6 and the heat dissipation frame 8. A baffle 9 is fixed to the upper end of the heat dissipation frame 8 and is located above the lower opening 11.

[0024] Through a unique "top-out, bottom-in" heat dissipation duct design, air enters the enclosure through the lower opening 11. The components inside the enclosure generate heat, and the air absorbs the heat and rises, exiting from the upper opening 17 on the top 3 of the enclosure. The lower opening 11 is hidden inside the heat dissipation frame 8 and shielded by an inclined baffle 9, effectively preventing direct intrusion of rainwater. This structure greatly optimizes heat dissipation efficiency without sacrificing the waterproof rating, perfectly resolving the inherent contradiction between waterproofing and heat dissipation.

[0025] The baffle 9 is installed at an angle downwards and the end of the baffle 9 is bent. The upper end of the heat dissipation frame 8 is set at an angle to improve the heat dissipation effect of the lower opening 11. The lower end of the bottom frame 6 is fixedly connected to the base 7, and the bottom of the base 7 is fixedly connected to the casting plate 19 for installation between the base plate and the ground.

[0026] The bottom heat dissipation frame 8, baffle 9 and connecting port 10 form a physical water barrier. The inclined and bent design of baffle 9 can efficiently guide rainwater and prevent it from splashing into or flowing into the lower heat dissipation port. The base 7 raises the bottom frame 6 to further prevent water from entering the heat dissipation frame 8.

[0027] A sealing ring 5 is snapped onto the frame 1. The sealing ring 5 is rectangular in shape. The door 2 is pressed against the sealing ring 5 to prevent water from entering from the side of the frame 1.

[0028] The sealing ring 5 increases the seal between the frame 1 and the door 2, preventing water from entering the box.

[0029] The sealing ring 5 includes an arc-shaped extrusion end 20 and a rectangular snap-fit ​​end 21. The door 2 is extruded and fitted with the arc-shaped extrusion end 20, and the rectangular snap-fit ​​end 21 is snap-fitted and installed with the frame 1.

[0030] The arc-shaped extrusion end 20 is squeezed by the door 2, causing deformation and fitting tightly against the box body. The rectangular snap-fit ​​end 21 is used for installation.

[0031] A slot 12 with one open end is formed inside the rectangular snap-fit ​​end 21. The slot 12 is inserted into the frame 1 for installation. A snap-fit ​​plate 13 is fixed to the inner wall of the slot 12. The snap-fit ​​plate 13 is pressed into the frame 1.

[0032] The slot 12 facilitates the insertion and installation of the rectangular snap-fit ​​end 21 into the frame 1. The snap-fit ​​plate 13 presses against the frame 1, increasing the friction between the rectangular snap-fit ​​end 21 and the snap-fit ​​plate 13, thereby increasing the installation firmness of the sealing ring 5.

[0033] A connecting cavity 15 is provided on the top of the box 3. The connecting cavity 15 is U-shaped. One end of the connecting cavity 15 is located inside the frame 1, and the other end is located outside the frame 1. An extension plate 16 is fixed to the end of the connecting cavity 15 located outside the frame 1. An upper opening 17 is provided on the extension plate 16.

[0034] The hot air inside the ring network box rises and passes through the upper opening 17 from the connecting cavity 15, thus being discharged. The connecting cavity 15 connects the inside and outside of the box.

[0035] The working principle of the outdoor ring network box with a waterproof structure provided by this utility model is as follows:

[0036] Through a unique "top-out, bottom-in" heat dissipation duct design, the upper opening 17 is located on the top of the box 3, and the lower opening 11 is hidden inside the heat dissipation frame 8 and shielded by an inclined baffle 9. The base 7 then lifts the bottom frame 6, and the casting plate 19 is poured on the ground, effectively preventing direct intrusion of rainwater. Air enters from the bottom opening 11 which is shielded, is heated internally, and then exits from the top opening 17. This structure greatly optimizes heat dissipation efficiency without sacrificing the waterproof rating, perfectly resolving the inherent contradiction between waterproofing and heat dissipation.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
