The bottom plate 2 should also be provided with a convex for setting the screw In order to prolong the service life of the screw, a rolling bearing should be arranged between the driving screw 10 and the base to reduce the wear of the screw.

[0019] Such as figure 1 , figure 2 , Figure 5 As shown, optionally, the bottom plate 2 is further provided with a locking mechanism for locking the driving gear 13 at a fixed position. The locking mechanism locks a block 16, and the lock block 16 is in a tooth shape and is in contact with The driving gear 13 has the same modulus. The locking block 16 is slidably connected to the bottom plate 2, and the bottom plate 2 is provided with a slideway 17 for allowing the locking block 16 to slide, and the locking block 16 is provided with The slider 18 adapted to the slideway 17, the cross-sectional shape of the slideway 17 is an arc shape, the cross-sectional shape of the slider 18 is adapted to the slideway 17, and the bottom plate 2 is also provided There is a locking screw 19 for fixing the locking block 16 in a proper position. The bottom plate 2 is provided with a locking screw hole matching the locking screw 19, and the locking screw hole communicates with the slideway 17 , An anti-loosening washer should be arranged between the locking screw 19 and the bottom plate 2 to prevent the locking screw 19 from loosening during use.

[0020] Such as figure 1 , figure 2 , Figure 7 As shown, optionally, a reinforcing rib 20 is provided between the vertical plate 3 and the bottom plate 2 to improve the connection strength between the vertical plate 3 and the bottom plate 2, and the reinforcing rib 20 is provided on the vertical plate 3 and the bottom plate 2 by welding. In between, the vertical plate 3 is also provided with a number of ribs 21 for improving the strength of the vertical plate 3, the ribs 21 and the vertical plate 3 are an integrated structure, the reinforcing ribs 20 can also be detachable The connection mode is set between the vertical plate 3 and the bottom plate 2, and the cross-sectional shape of the rib 21 is preferably rectangular.

[0021] Such as figure 2 , image 3 , Figure 7 As shown, optionally, the connection between the vertical plate 3 and the housing 4 is provided with a waterproof structure for preventing rainwater from entering the inside of the housing 4. The waterproof structure includes a waterproof structure arranged on the vertical plate 3 and extending into the housing 4 The shoulder 22 is bonded with a waterproof gasket 23, the waterproof gasket 23 is provided with a plurality of ribs 24 for forming a labyrinth-type waterproof structure, the ribs 24 and the waterproof gasket 23 is a one-piece structure.

[0022] Such as figure 1 , Image 6 , Figure 7 As shown, optionally, the box body 1 is further provided with a waterproof tube 25 for preventing rainwater from entering the inside of the shell 4 along the wire hole 15, and the waterproof tube 25 includes a right half 26 of the shell 4. And the left half 27 provided on the vertical plate 3, the left half 27 and the right half 26 are connected with a step structure 28, the step structure 28 is glued to the waterproof pad, the left half 27 Both the right half 26 and the left half 26 are provided with rectangular strips 29 for preventing the left half 27 and the right half 26 from being deformed. The height of the opening at one end of the waterproof tube 25 away from the shell 4 should be lower than that of the waterproof tube 25 and the shell 4. The height of the opening at one end of the contact.

[0023] During the use of the above technical solutions, such as Figure 7 As shown, when assembling, first install the bottom plate 2 in a suitable position, and then assemble the partition 6, the vertical plate 3 and the electrical components in sequence, and finally assemble the housing 4. During specific use, the electrical components located in the housing 4 During the overhaul process, the drive handle 12 can be conveniently operated to slide the housing 4, so that the electrical components located in the housing 4 are exposed to the outside, so that the overhaul operation of electrical parts is very convenient. Only the drive handle 12 needs to be operated during use. The shell 4 can be operated for easy operation. In addition, in order to prevent the shell 4 from being opened by unrelated persons during specific use, a lock body can be provided between the shell 4 and the vertical plate 3. Personnel keep it in order to prevent unrelated persons from opening the shell 4; by setting the box 1 as the vertical plate 3 and the shell 4, the electrical components in the box 1 can be directly slid away from the shell 4 during the overhaul or installation process. The assembly board 5 and the partition 6 on the bottom plate 2 are exposed to the outside, and the electrical components have a large operating space during installation or maintenance, so that the electrical components can be easily installed or repaired, which is very convenient to use; in addition, through the adjustment of the screw and With the nut 11, the housing 4 can be directly matched with the vertical plate 3 after the electrical components are installed or overhauled. Because the screw and the nut 11 have a self-locking function, the housing 4 will not move automatically, and the operation is very convenient.

[0024] The above are only the preferred embodiments of the present invention, which are intended to embody the outstanding technical effects and advantages of the present invention, and are not intended to limit the technical solutions of the present invention. Those skilled in the art should understand that all modifications, changes or substitutions of technical features based on the technical content of the present invention should be covered by the technical scope claimed by the appended claims of the present invention.
