Example Embodiment

[0018] With reference to the accompanying drawings, the metering box used in the distribution network of the present invention will be further described. Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 As shown, a metering box for a power distribution network includes a box body 1, the box body 1 includes a bottom plate 2, and the bottom plate 2 is provided with a vertical plate 3 and used to cooperate with the vertical plate 3 to enclose the inner cavity of the box body 1. The bottom plate 2 is also provided with an assembly plate 5 for installing power distribution components and a partition plate 6 for partitioning the inner cavity of the box 1 into at least two placement chambers. The assembly plate 5 is welded The partition plate 6 is set on the bottom plate 2 by fixing bolts 7, and the bottom plate 2 is provided with strip holes for passing through the fixing bolts 7, and the vertical plate 3 is set on the bottom plate by welding. On the bottom plate 2, the housing 4 is slidably connected to the bottom plate 2, the bottom plate 2 is provided with a sliding rail 8, and the housing 4 is provided with a sliding groove 9 that matches the sliding rail 8. The bottom plate 2 is also provided with a drive screw 10 for driving the housing 4 to slide. The housing 4 is provided with a nut 11 adapted to the drive screw 10, and the drive screw 10 is rotatably connected to the bottom plate 2. In the above, the nut 11 is arranged on the housing 4 by welding, the bottom plate 2 is also provided with a drive handle 12 for operating the drive screw 10 to rotate, and the drive handle 12 is provided with a driving gear 13, the The driving screw 10 is provided with a driven gear 14 that meshes with the driving gear 13, and also includes a wiring hole 15 provided on the box 1 for wiring. 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.
