[0002] Outdoor box and cabinet equipment are directly contacted with the outside world, and generally need to meet the requirements of rain and dust prevention. Generally, electrical equipment is installed and stored inside the outdoor box and cabinet. In the case of severe rain, snow and wind weather, the external structure should provide sufficient protection to the internal equipment to ensure the performance of the internal fragile parts and prevent safety accidents.

[0003] In the prior art, common waterproof measures for electrical equipment mainly rely on sealing strips and water baffle designs. However, these designs are prone to poor sealing effect in long-term use, causing water to penetrate into the equipment and affecting its normal operation.

In the structure of the outdoor double-door, the structural gap between the door frame 1 and the door plate is inevitable, and the traditional sealing and water retaining method has poor waterproof effect in long-term use. In the embodiment of the application, the structure of the door frame 1 and the first door plate 2 and the second door plate 3 can guide the rainwater entering the gap to be discharged along the periphery of the door frame 1, and effectively prevent the rainwater from entering the cabinet. Specifically, the first flow guide groove 1a is formed in the upper edge frame 11 and the side edge frame 12, the drainage groove 1b is formed in the lower edge frame 13, and the overall structure of the door frame 1 adopts an embedded design, that is, the periphery of the door frame 1 is provided with a curled edge, wherein the curled edge is attached to, welded to or integrally formed with the cabinet, which is not limited in the embodiment.

[0061] It should be noted that the forming method of the first flow guide groove 1a and the drain groove 1b on the door frame 1 is not limited here, and the forming method of the second flow guide groove 2a on the first door plate 2 is not limited, which can be formed by welding multiple metal structures, preferably, the upper frame 11, the side frame 12 and the lower frame 13 are integrally formed, and then the whole structure of the door frame 1 is formed by welding, which is beneficial to the integrity of the first flow guide groove 1a and the drain groove 1b, and avoids rusting or damage of the first flow guide groove 1a and the drain groove 1b formed by welding in the case of long-term and rainwater contact. The forming method of the second flow guide groove 2a is also integrally formed with the first door plate 2. Here, the specific shape of the first water baffle 111 is not limited, which can be a straight plate arranged on the outside of the bottom of the upper frame 11, and is arranged parallel to the first door plate 2 and the second door plate 3. In the case of closing the double doors, the first door plate 2 and the second door plate 3 abut against the first water baffle 111. In the preferred case, the first water baffle 111 is arranged in a straight U-shaped structure, that is, a straight plate parallel to the first door plate 2 and the second door plate 3, and side plates are arranged on both sides of the straight plate, which can block the rainwater from flowing to both sides. Through such arrangement, the first water baffle 111 forms a small groove structure for guiding water downward, and guides the rainwater in the gap at the top of the first door plate 2 and the second door plate 3 to the second flow guide groove 2a.

[0062] In combination Figures 1 to 11In the preferred case, the first door plate 2 comprises a first outer door plate 21 and a first inner door plate 22, the first outer door plate 21 is formed with a second water baffle 221 on the top, the second water baffle 221 is arranged obliquely to the first guide groove 1a, one end of the second water baffle 221 is arranged in the first guide groove 1a, and the first inner door plate 22 is arranged inside the first guide groove 1a; the second door plate 3 comprises a second outer door plate 31 and a second inner door plate 32, the second outer door plate 31 is formed with a third water baffle 311 on the top, the third water baffle 311 is arranged obliquely to the first guide groove 1a, one end of the third water baffle 311 is arranged in the first guide groove 1a, and the second inner door plate 32 is arranged inside the first guide groove 1a. Through such arrangement, the second water baffle 221 and the third water baffle 311 can separate the rainwater entering the gap of the upper frame 11 from the inside of the first door plate 2 and the second door plate 3, and at the same time, the second water baffle 221 and the third water baffle 311 are obliquely arranged to the first guide groove 1a and one end is arranged in the first guide groove 1a, which is more conducive to the rainwater on the surface of the second water baffle 221 and the third water baffle 311 flowing into the first guide groove 1a. In addition, the first inner door plate 22 and the second inner door plate 32 are arranged inside the first guide groove 1a, that is, the top and both sides of the first inner door plate 22 and the second inner door plate 32 are provided with the first guide groove 1a, and the bottom is provided with a drainage groove 1b. Through such arrangement, combined with the arrangement of the sealing assembly 5, it can effectively prevent rainwater from entering the first inner door plate 22 and the second inner door plate 32, thereby ensuring the overall waterproof performance of the double-opening door. Specifically, after the double-opening door is arranged on the cabinet, the upper door frame 1 is usually arranged horizontally, and the first door plate 2 and the second door plate 3 are opened to both sides. At this time, the first guide groove 1a formed by the upper frame 11 is located above the first inner door plate 22 and the second inner door plate 32, the second water baffle 221 is formed on the top of the first outer door plate 21, the third water baffle 311 is formed on the top of the second outer door plate 31, the second water baffle 221 and the third water baffle 311 are arranged in the direction of the first inner door plate 22 and the second inner door plate 32, and extend into the space where the first guide groove 1a is located, thereby being able to guide the rainwater in the gap between the upper frame 11 and the first door plate 2 and the second door plate 3 to the first guide groove 1a. Here, the connection relationship between the second water baffle 221 and the first outer door plate 21 is not limited, nor is the connection relationship between the third water baffle 311 and the second outer door plate 31, which can be welded, and preferably is formed by bending to improve the integrity of the first outer door plate 21 and the second outer door plate 31.In the preferred case, the second water guide groove is arranged between the first inner door plate 22 and the second inner door plate 32, specifically, the second water guide groove is inwardly bent and integrally formed on the first outer door plate 21, the side wall of the second water guide groove is attached to one side of the first inner door plate 22, preferably, the outer contour depth of the second water guide groove is the same as the thickness of the first inner door plate 22 and the second inner door plate 32, through such arrangement, the second water guide groove 2a is in the same plane with the second inner door plate 32 and the second inner door plate 32, which ensures the drainage effect and saves the overall structural space, and can also well block the rainwater from entering the box along the side edge of the abutment of the first inner door plate 22 and the second inner door plate 32.

[0063] It should be noted that the connection relationship between the first inner door plate 22 and the first outer door plate 21 is not limited here, which can be welding or screwing, or integrally formed. The thickness and internal structure of the first inner door plate 22 are not limited, specifically, the four edges of the first inner door plate 22 are located inside the four edges of the first outer door plate 21, that is, the front area of the first inner door plate 22 is smaller than the first outer door plate 21, through such arrangement, when the first door plate 2 is closed, the first inner door plate 22 can be arranged inside the circumferential direction of the first water guide groove 1a and the drainage groove 1b, thereby realizing the drainage of rainwater from the four sides of the first inner door plate 22, avoiding the rainwater from entering the box. The structure of the second inner door plate 32 and the second outer door plate 31 is similar to that of the first inner door plate 22 and the first outer door plate 21, which will not be described here.

Specifically, the fourth water baffle 221 is provided with a first face and a second face perpendicular to each other, and in the closed state of the first door plate 2 and the second door plate 3, the first face is overlapped with the first water baffle 111, and the second face is fixedly connected to the side wall of the second guide groove 2a close to the first inner door plate 22, which can block the rainwater from entering the first inner door plate 22 along the side of the first water baffle 111. At the same time, in order to ensure the opening and closing action of the first door plate 2 and the second door plate 3, a certain gap is reserved at the top of the first water baffle 111 and the second guide groove 2a, and the bottom of the first face of the fourth water baffle 221 is arranged above the second guide groove 2a, which can effectively guide the rainwater into the box along the gap between the first water baffle 111 and the second guide groove 2a. It should be noted that the bottom of the first face of the fourth water baffle 221 is at least parallel to the top of the second guide groove 2a to ensure the water blocking effect, and optionally, the bottom of the first face of the fourth water baffle 221 can also extend into the second guide groove 2a to further guide the rainwater entering the gap into the second guide groove 2a. The forming method of the fourth water baffle 221 is not limited here, and the preferred method is bending forming, and the specific fixing method of the second face of the fourth water baffle 221 is not limited, which can be that one side of the second face is directly welded to the inner side of the first outer door plate 21, and the other side is welded to the top of the first inner door plate 22 to achieve the water blocking effect, or the second guide groove is extended close to the inner wall of the second inner door plate 32 and welded to the second face of the fourth water baffle 221. Through such a setting, the first door plate 2 and the second door plate 3 can avoid the upper door frame 1 and the first water baffle 111 during opening and closing, and also guide the rainwater in the gap to the second guide groove 2a to achieve the water blocking effect.

[0065] In combination Figures 10 to 14 In the preferred case, the first inner door plate 22 is further provided with a first guide plate 222 on the top, one end of the first guide plate 222 abuts against the first outer door plate 21, and the other end of the first guide plate 222 is flush with the inner wall of the second guide groove 2a close to the first inner door plate 22. Specifically, in extreme cases, such as during the opening and closing process of double doors in rainy days or in heavy rain environment, rainwater may enter the top side of the first inner door plate 22, at this time the first guide plate 222 blocks the rainwater from entering the box along the top side of the first inner door plate 22, and at the same time guides the rainwater to the second guide groove 2a, thereby improving the overall waterproof performance of the structure. The specific structure of the first guide plate 222 is not limited here, which can block the rainwater and guide the rainwater to the second guide groove 2a on the side of the top of the second inner door plate 32 close to the fourth water baffle 221.
