The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.
[0028] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.
[0029] An explosion-proof high-voltage distribution box, as Figures 1 to 7 shown, includes a box body 100. A lid 110 is rotatably connected to the top of the box body 100. A flip mechanism 200 is installed on one side of the inner cavity of the box body 100 at the bottom of the lid 110. A sliding assembly 300 is installed on one side of the box body 100. A sealing assembly 400 is installed between the bottom of the lid 110 and the flip mechanism 200;
[0030] The entire distribution box controls the opening and closing of the lid 110 through the flip mechanism 200 and the sliding assembly 300. The sliding assembly 300 makes the opening and closing of the lid 110 more labor-saving. At the same time, it cooperates with the sealing assembly 400 to complete the sealing of the entire distribution box. On the one hand, it prevents external humid air from entering the distribution box and causing faults such as short circuits. On the other hand, it prevents the electric sparks generated during the operation of the distribution box from splashing out and meeting the external explosive gas mixture, resulting in an explosion and endangering the lives and health of citizens.
[0031] The flip mechanism 200 includes two groups of fixed plates 210 fixed on both sides of the inner cavity of the box body 100. One side of the fixed plate 210 is provided with a J-shaped sliding groove 211. A connecting rod 230 is arranged between the two groups of fixed plates 210. Both ends of the connecting rod 230 are clamped on one side of the J-shaped sliding groove 211. Moving plates 220 are installed at both ends of the connecting rod 230. The moving plates 220 are located on one side of the fixed plate 210 and slide. A first rotating guide rod 240 is rotatably connected to one side of the moving plate 220 at one end of the connecting rod 230. The other end of the first rotating guide rod 240 is rotatably connected to a second rotating guide rod 250. The other end of the second rotating guide rod 250 is rotatably connected to the fixed plate 210. A first rotating shaft 260 penetrates through one side of the second rotating guide rod 250. The other end of the first rotating shaft 260 penetrates through the fixed plate 210 and the box body 100 and is rotatably connected to a first gear 270. A sliding column 280 penetrates through one side of the moving plate 220. The other end of the sliding column 280 is clamped into the J-shaped sliding groove 211.
[0032] The installer controls the rotation of the first gear 270 through the sliding component 300, drives the rotation of the first rotating shaft 260, thereby driving the rotation of the second rotating guide rod 250. The first rotating guide rod 240 rotatably connected to the second rotating guide rod 250 starts to rotate. The two first rotating guide rods 240 drive the connecting rod 230 between them to move upward, thereby driving the moving plate 220 fixed thereto to move upward accordingly. The sliding column 280 clamped in the J-shaped sliding groove 211 slides in the arc-shaped sliding groove, so that at the beginning, the moving plate 220 first moves vertically upward for a certain distance and then makes a folding movement, driving the cover 110 fixed to the moving plate 220 to open, eliminating a large number of nuts fixed on the cover 110 of the existing explosion-proof high-voltage distribution box, reducing the installation or maintenance time of the installer, and improving work efficiency.
[0033] Please refer specifically to Figure 3 As shown, a fixing screw 221 is installed on the top of the moving plate 220. The moving plate 220 and the bottom of the cover 110 are fixedly connected by the fixing screw 221.
[0034] The moving plate 220 and the cover 110 are fixedly connected by the fixing screw 221, making the fixing of the cover 110 and the moving plate 220 more stable.
[0035] Please refer specifically to Figure 4. The sliding assembly 300 includes a control box 310 installed on one side of the box body 100. At the bottom of the inner cavity of the control box 310, a sliding guide rail 320 is fixed. A rack 330 is slidably connected to the upper surface of the sliding guide rail 320. One end of the rack 330 meshes with a second gear 340. One side of the second gear 340 is rotatably connected to a second rotating shaft 350. The other end of the second rotating shaft 350 is rotatably connected to one side of the inner cavity of the control box 310. One end of the second gear 340 meshes with the first gear 270. The other end of the rack 330 meshes with a sector gear 360. One side of the sector gear 360 is rotatably connected to a third rotating shaft 370. The other end of the third rotating shaft 370 is rotatably connected to one side of the inner cavity of the control box 310. One end of the sector gear 360 is fixed with a rotating handle 380.
[0036] The installer rotates the rotating handle 380. The rotating handle 380 and the sector gear 360 start to rotate around the third rotating shaft 370. The rack 330 meshing with the sector gear 360 starts to slide on the sliding guide rail 320. The second gear 340 meshing with the other end of the rack 330 starts to rotate, driving the meshing first gear 270 to rotate. At the same time, the rotating handle 380 and the sector gear 360 form a labor-saving lever, enabling the installer to open the lid 110 more easily.
[0037] Please refer specifically to Figure 1 as shown in the figure, an activity slot is opened at the top of the control box 310.
[0038] An activity slot is opened at the top of the control box 310, providing a rotating space for the rotation of the rotating handle 380.
[0039] Please refer specifically to Figure 5 and 7 as shown in the figure, a sealing ring 410 is installed on the side of the inner cavity of the box body 100 above the fixing plate 210. A groove is provided in the middle of the sealing ring 410. A sealing block 420 is installed at the bottom of the lid 110. The sealing block 420 is engaged with the groove of the sealing ring 410.
[0040] When the lid 110 is closed, the sealing block 420 at the bottom of the lid 110 is engaged into the groove of the sealing ring 410, completing the sealing of the distribution box.
[0041] Please refer specifically to Figure 5 and 7 as shown in the figure, the sealing ring 410 and the sealing block 420 are made of rubber material.
[0042] The sealing ring 410 and the sealing block 420 being made of rubber material makes the sealing effect of the entire distribution box better.
[0043] Please refer specifically to Figure 6 as shown in the figure, an airbag pad 430 is installed at the bottom of the groove of the sealing ring 410. The airbag pad 430 is a convex airbag.
[0044] When the installer closes the cover 110, after the sealing block 420 is engaged with the sealing ring 410, the sealing block 420 continues to receive a downward force and begins to squeeze the convex airbag pad 430, squeezing the gas bulging in the middle of the airbag pad 430 to both sides, increasing the sealing effect and making the sealing effect better.
[0045] During use, the entire distribution box controls the opening and closing of the cover 110 through the flip mechanism 200 and the sliding assembly 300. The sliding assembly 300 makes it easier to open and close the cover 110. The installer controls the rotation of the first gear 270 through the sliding assembly 300, driving the rotation of the first rotating shaft 260, thereby driving the rotation of the second rotating guide rod 250. The first rotating guide rod 240 rotatably connected to the second rotating guide rod 250 begins to rotate. The two groups of first rotating guide rods 240 drive the connecting rod 230 therebetween to move upward, thereby driving the moving plate 220 fixed thereto to move upward accordingly. The sliding column 280 engaged in the J-shaped sliding groove 211 slides in the arc-shaped sliding groove, so that at first the moving plate 220 moves vertically upward for a certain distance and then makes a folding movement, driving the cover 110 fixed to the moving plate 220 to open. This eliminates a large number of nuts fixed on the cover 110 of the existing explosion-proof high-voltage distribution box, reduces the installation or maintenance time of the installer, improves work efficiency, and at the same time cooperates with the sealing assembly 400 to complete the sealing of the entire distribution box. On the one hand, it prevents external humid air from entering the distribution box and causing faults such as short circuits. On the other hand, it prevents the electric sparks generated when the distribution box is working from splashing out and meeting the external explosive gas mixture, resulting in an explosion and endangering the lives and health of citizens.
