[0031] Embodiment 1:

[0032] Please refer to Figure 1-5A novel electrical junction box comprises a box body 1 and a box cover 2. A wiring seat 6 is arranged at the center of the inner side of the box body 1. Four screw rods 7 are evenly fixed to the bottom end of the box cover 2. A positioning column 8 is fixed to the lower end of each screw rod 7. Four hollow screw barrels 9 are rotatably connected to the lower ends of the four positioning columns 8 inside the box body 1. The positioning columns 8 are slidably connected to the hollow screw barrels 9. The screw rods 7 are threadedly connected to the hollow screw barrels 9. When the box cover 2 needs to be installed with the box body 1, the four positioning columns 8 can be conveniently slid into the inner sides of the four hollow screw barrels 9 by sliding the positioning columns 8 and the hollow screw barrels 9, thereby positioning the position of the box cover 2.

[0033] A first flat gear 13 is fixed to the outside of each hollow screw barrel 9 and located at the lower end of the box body 1, a gear groove 14 is provided at the center of the bottom end of the box body 1, and a fixed shaft 15 is fixed to the center of the bottom end of the box body 1 and located inside the gear groove 14. A movable sleeve 16 is movably connected to the outside of the fixed shaft 15, and a second flat gear 17 is fixed to the outside of the movable sleeve 16. The second flat gear 17 is slidably connected to the gear groove 14, and the second flat gear 17 is meshed with the first flat gear 13. The second flat gear 17 is driven to rotate by rotating the movable sleeve 16, and the meshing of the second flat gear 17 with the first flat gear 13 makes it convenient to drive the four hollow screw barrels 9 to rotate in the same direction at the same time, and then cooperate with the threaded connection of the hollow screw barrel 9 and the screw rod 7, so as to facilitate the quick installation of the box cover 2;

[0034] When there is no need to rotate the second flat gear 17, in order to facilitate the limiting and fixing of the second flat gear 17, so as to make the box cover 2 more firmly installed, the lower end of the movable sleeve 16 is rotatably connected to the limiting pressure block 19, and the limiting pressure block 19 is slidably connected to the fixed shaft 15. A spring 20 is further provided on the outer side of the fixed shaft 15 and at the lower end of the limiting pressure block 19. The two ends of the spring 20 are respectively fixed to the limiting pressure block 19 and the fixed shaft 15. In order to facilitate the grasping and rotation of the movable sleeve 16, a handle 18 is further fixed to the outer side of the movable sleeve 16.

[0035] Embodiment 2:

[0036] The novel electrical junction box provided in Example 1 is further optimized, specifically, as follows: Figure 2 and Figure 3 As shown, in order to ensure the moisture-proof performance between the box body 1 and the box cover 2 after installation, a sealing side frame 3 is fixed to the outer side of the upper end of the box body 1, a sealing side plate 4 is fixed to the outer side of the box cover 2, the lower end of the sealing side plate 4 is located inside the sealing side frame 3 and fits with the sealing side frame 3, and a sealing ring gasket 5 is also fixed to the bottom end of the box cover 2 and located inside the box body 1, and the sealing ring gasket 5 fits with the box body 1;

[0037] A moisture-proof box 10 is fixed on the inner side of the box body 1 and on both sides of the wiring seat 6. A dehumidifier 11 is arranged on the inner side of each moisture-proof box 10. A support shaft 12 is fixed at both ends of the dehumidifier 11. The support shaft 12 is rotatably connected to the moisture-proof box 10. The support shaft 12 is rotatably connected to the moisture-proof box 10, so that when the box body 1 is turned over, the dehumidifier 11 can rotate without following the box body 1 due to its own weight, and then fully absorb the moisture inside the box body 1 through the moisture-proof box 10;

[0038] The use process of the new electrical junction box provided by the utility model is as follows: when it is necessary to install the separated box cover 2 and the box body 1, the four positioning columns 8 are slid into the inner sides of the four hollow screw barrels 9, and then the position of the box cover 2 is positioned and the box cover 2 is gently pressed down. At this time, the grab handle 18 pulls the movable sleeve 16 to drive the second flat gear 17 to slide out from the inner side of the gear groove 14, and squeezes the spring 20, and then the handle 18 is turned to drive the movable sleeve 16 and the second flat gear 17 to rotate, and the meshing of the second flat gear 17 and the first flat gear 13 facilitates the four hollow screw barrels 9 to rotate in the same direction at the same time, and then cooperates with the threaded connection of the hollow screw barrel 9 and the screw 7 to facilitate the rapid installation of the box cover 2;

[0039] When the handle 18 is turned to drive the movable sleeve 16 and the second flat gear 17 to rotate, the movable sleeve 16 is connected to the limit pressing block 19 through rotation, so as to prevent the limit pressing block 19 from rotating with the movable sleeve 16, thereby preventing the spring 20 from being twisted;

[0040] When the box cover 2 is installed and fits tightly to the box body 1, the handle 18 is released to push the limiting pressure block 19 through the elastic force characteristics of the spring 20, so that the movable sleeve 16 and the second flat gear 17 slide in the direction close to the gear groove 14, so that the second flat gear 17 slides back into the inner side of the gear groove 14, and then the second flat gear 17 is limited and fixed, so that the installation of the box cover 2 is more secure.
