Detailed Description

Referring to fig. 1, a power distribution cabinet with an adjustable base structure comprises a base plate 1, a threaded column 11 is fixed on the base plate 1, a barrel 12 is slidably sleeved on the threaded column 11, a base 13 is fixed on the barrel 12, a box 18 is fixed on the base 13, an inner cavity 14 is arranged on the base 13, first heat dissipation holes 15 are communicated with the upper side and the lower side of the inner cavity 14, a built-in plate 16 is slidably arranged in the inner cavity 14, second heat dissipation holes 17 communicated with the first heat dissipation holes 15 are arranged on the built-in plate 16, and a universal wheel 19 is fixed at the lower end of the base plate 1.

Referring to fig. 1, a bearing 2 is disposed on the built-in plate 16, a threaded rod 21 is in interference fit in the bearing 2, and the bearing 2 can rotate in cooperation with the threaded rod 21.

Referring to fig. 1, a threaded ring 22 is fixedly embedded in an opening position of an inner wall of the inner cavity 14, and the threaded rod 21 and the threaded ring 22 are arranged in a threaded manner, so that the built-in plate 16 can be driven to move, and the staggered distribution of the two heat dissipation holes is realized.

Referring to fig. 1 and 2, a cylinder 3 is fixed at the lower end of the base 13, the cylinder 3 covers the first heat dissipation hole 15, a dust screen 31 is fixed at the lower end of the cylinder 3, clamping seats 34 are fixed on both sides of the cylinder 3, elastic clips 35 clamped with the clamping seats 34 are fixed on both sides of the dust screen 31, the shapes of the elastic clips 35 and the clamping seats 34 are regular hexagons, and the elastic clips 35 are made of rubber materials.
