[0003] When installing and using distribution boxes, it is often necessary to install a rain cover on the top of the distribution box for rain protection. However, conventional fixed rain covers are not convenient for the maintenance of distribution boxes, and rain covers that are convenient for the maintenance of distribution boxes often have weak pressure resistance. Therefore, there is an urgent need for a rain cover that is both convenient for maintenance and has high pressure resistance.

[0004] In view of this, this utility model is proposed. Utility Model Content

The top plane of the rotating shaft is connected to the bottom of the hinged plate. The hinged plate is a plate with the rear wall facing upward. The follower plate has the same shape as the hinged plate and is fixedly connected between the symmetrical frame plates.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a flip-type double-layer rain cover structure includes: a bottom frame 20, which is a rectangular frame, and a fixed frame 21 symmetrically fixed to the top of the bottom frame 20. The fixed frame 21 is a rectangular plate. This is existing technology, so it will not be described in detail here.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a rainproof structure is installed on the top of the bottom frame 20 to protect the area below from rain. The rainproof structure includes: a rear side plate 22, a fixed cover 23, a rotating shaft 30, a hinged plate 31, a frame plate 32, and a follower plate 34. The rear side plates 22 are symmetrically and fixedly connected to the top of the rear wall of the bottom frame 20. The fixed cover 23 is fixedly connected between the symmetrical rear side plates 22. The rotating shaft 30 is rotatably connected between the symmetrical fixed frames 21. The hinged plate 31 is fixedly connected to the top of the rotating shaft 30. The frame plate 32 is symmetrically and fixedly connected to the top of the hinged plate 31. The follower plate 34 is located above the hinged plate 31. The hinged plate 31 and the fixed cover 23 can cover the top of the bottom frame 20.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the rear plate 22 is a right-angled trapezoidal plate, and the symmetrical rear plates 22 are located on the rear wall of the symmetrical frame 21. The fixed cover 23 is a plate with a broken cross section, and the rotating shaft 30 is a rod with a semi-capsule cross section. There is a distance between the top of the fixed cover 23 and the top of the rear plate 22. The top of the follower plate 34 can be flush with the top of the rear plate 22. The two ends of the rotating shaft 30 are symmetrically fixed with cylinders. The cylinders on both sides of the rotating shaft 30 can pass through the wall of the symmetrical frame 21 and rotate to connect with the wall of the frame 21. The top plane of the rotating shaft 30 is connected to the bottom of the hinge plate 31. The hinge plate 31 is a plate with the rear wall facing upward. The follower plate 34 and the hinge plate The shapes of the 31 are consistent. The follower plate 34 is fixedly connected between the symmetrical frame plates 32. The rainproof structure also includes a contact plate 35, a movable suction rod 36 and a fixed suction rod 37. The contact plate 35 is fixedly connected to the front wall of the rotating shaft 30. The movable suction rod 36 is fixedly connected to the front wall of the contact plate 35. The fixed suction rod 37 is fixedly connected to the front wall of the fixed cover 23. The contact plate 35 is a rectangular plate. The movable suction rod 36 is a rod with a fan-shaped cross section. The length of the movable suction rod 36 is the same as that of the contact plate 35. The front wall of the fixed cover 23 has a rectangular slot. The fixed suction rod 37 is fixedly connected in the rectangular slot of the fixed cover 23. The fixed suction rod 37 can be magnetically connected to the movable suction rod 36.

[0032] In practical use, after the bottom frame 20 and the distribution box are installed, the flap 31 is flipped forward with the pivot 30 as the center. The flap 31 can drive the frame plate 32, the rotating pull column 33, the follower plate 34, the abutment plate 35 and the movable suction rod 36 to rotate 180 degrees simultaneously. After the flap 31 is flipped, the wall of the frame plate 32 will contact and stick to the top of the bottom frame 20, and the wall of the movable suction rod 36 will magnetically attract the fixed suction rod 37. At this time, the bottom of the follower plate 34 will cover the opening at the top of the bottom frame 20 with the fixed cover 23. The same fixed cover 23 can also be installed on the bottom of the fixed cover 23 (not shown in the figure). When the distribution box needs to be inspected, the flap 31 is flipped backward to stick to the fixed cover 23 so that the top front half of the bottom frame 20 is open.

[0033] In summary, by setting up a rainproof structure, the maintenance of the distribution box can be facilitated by flipping the flap 31 and the follower plate 34. Furthermore, the overlapping arrangement of the follower plate 34 and the flap 31, as well as the double-layer solid cover 23, can effectively improve the overall pressure resistance of the device. Therefore, this solution has both high pressure resistance and facilitates the maintenance of the distribution box.

[0034] like Figure 3As shown, the wall of the frame 21 is provided with a tension structure, which includes a fixed tie column 38 and a rotating tie column 33. The fixed tie column 38 is fixedly connected to the side wall of each frame 21 and the fixed tie column 38 is fixedly connected to the side wall of each frame plate 32. The rotating tie column 33 and the fixed tie column 38 are both composed of the same cylinder and disk. A tension spring is also installed between the rotating tie column 33 and the fixed tie column 38 on each side. The two ends of the tension spring are respectively sleeved with the cylinder of the rotating tie column 33 and the fixed tie column 38.

[0035] In practical use, as the hinge 31 drives the frame 32 to rotate and flip, it will also drive the rotating pull column 33 to rotate synchronously. As the rotating pull column 33 rotates, it will pull the tension spring. When the rotating pull column 33 moves to the rear with the hinge 31, the tension spring will pull the rotating pull column 33 downward. When the rotating pull column 33 moves to the front with the hinge 31, the tension spring will pull the rotating pull column 33 downward.

[0036] In summary, by setting up a tension structure and using symmetrical tension springs on both sides of the device, it is easy to apply tension to the flap 31 when it is flipped, so that the flap 31 always maintains the flipped state and improves the stability of the flap 31 when it is flipped.

[0037] A distribution box, not shown in the figure, includes a box body and all of the above-mentioned flip-type double-layer rainproof cover structures;

[0038] By setting up a flip-type double-layer rainproof cover structure, the circuit of the distribution box can be prevented from being affected by rainwater, thereby improving the safety of the distribution box.

[0039] Working principle: After the bottom frame 20 and the distribution box are installed, the flap 31 is flipped forward with the pivot 30 as the center. The flap 31 can drive the frame plate 32, the rotating pull column 33, the follower plate 34, the abutment plate 35 and the movable suction rod 36 to rotate 180 degrees simultaneously. After the flap 31 is flipped, the wall of the frame plate 32 will contact and fit with the top of the bottom frame 20, and the wall of the movable suction rod 36 will be magnetically attracted to the fixed suction rod 37. At this time, the bottom of the follower plate 34 will cover the opening at the top of the bottom frame 20 with the fixed cover 23.
