The distribution box is generally used for the power distribution and conversion in low-voltage circuits and plays a role in control and protection. The distribution box usually consists of corresponding power switches, leakage protectors, branch circuit breakers, surge protectors, TVs, telephones, metering controllers, timing switches, etc. In some special occasions, such as temporary construction sites, exhibitions, event venues, etc., it is necessary to frequently move and change the position of the distribution box. Therefore, portability has become one of the important considerations in the design of distribution boxes. A portable distribution box can be easily carried and moved to meet the power needs of these occasions, improve the flexibility and efficiency of power supply. A existing new type of portable distribution box can basically meet the daily use needs, but there are still some deficiencies that need to be improved.

[0003] The existing distribution boxes may tend to use heavier metal materials, such as iron, cold-rolled plates, etc., in material selection to ensure their structural strength and durability.

[0037] During use, first press the positioning post 44 into the guiding groove 42, and make the positioning post 44 squeeze the second spring 43. Then insert the handle 2 into the socket 41, and the restoring force of the second spring 43 pushes the positioning post 44 through the positioning hole 45, so as to achieve the purpose of installing the handle 2. Then, by pulling the insertion rod 39 in the direction away from the movable bin 37, the insertion rod 39 drives the slider 38 to slide in the movable bin 37, and the slider 38 and the movable bin 37 squeeze the first spring 310 until the insertion rod 39 slides out of the slot 311. Then rotate the support rod 33, and the support rod 33 drives the brake rod 32 to rotate in the fixed seat 31, and the brake rod 32 synchronously drives the roller 35 to rotate. The rotating roller 35 then drives another group of rollers 35 and the brake rod 32 to rotate through the belt 36, and the universal wheel 34 is turned to fit the ground. At this time, another group of slots 311 are aligned with the insertion rod 39, and then use the restoring force of the slider 38 to push the insertion rod 39 into the slot 311, so that the universal wheel 34 slides on the ground to achieve the purpose of moving the box body 1. At the same time, when the box body 1 is too heavy, turn the support rod 33 to contact the ground, and the support rod 33 supports the box body 1.
