Disclosed is a movable temporary-power-utilization construction power box which relates to a power box. At present, in temporary power utilization, a cable is pulled directly to be connected with a three-phase knife switch or a power-supply plate is used to lead a power supply from a fixed power box to a construction electrical device, which are unsafe and inconvenient. The movable temporary-power-utilization construction power box includes a box body, a base arranged at the lower end of the box body and a telescopic pull rod arranged at the back face of the box body. A knife switch, an electricity-leakage protector, a socket, a grounding copper bar and a grounding terminal are arranged in the box body. The base is provided with a universal wheel and two feet so that the box body is capable of being pulled or capable of standing. The back face of the box body is provided with a wire coil. A cable used for drag and drop and connected with the knife switch can be coiled on the wire coil. The other end of the knife switch is connected electrically with one end of the electricity-leakage protector through a connection wire and the other end of the electricity-leakage protector is connected electrically with the socket and a binding post. The socket is also electrically connected with a zero wire and a grounding wire. The base is a conductive body. The grounding wire is electrically connected with the base through the grounding terminal and the grounding copper bar. The movable temporary-power-utilization construction power box is convenient to operate and capable of improving construction safety and use flexibility.

As the further of technique scheme improved and supplemented, the utility model also comprises following additional technical feature.
The bottom surface of described casing is offered for wearing the wire guide of cable and earth connection.
Described casing comprise rectangle storage case, with the chamber door of storage case switching, described chamber door is positioned at the front side of storage case with sealing storage case, establishes door lock on case lid; Storage case bottom is provided with insulation board, and described plug-in strip, earth leakage protective device, socket, grounding copper bar are all located on insulation board; Described casing coated insulation layer.Insulating layer coating can be insulating varnish etc.
Beneficial effect:
1, the technical program makes every power consumption equipment be equipped with special-purpose separately power supply box, and be furnished with special-purpose plug-in strip and earth leakage protective device, make near the place of power supply control point convenient operation temporary electricity equipment simultaneously, while preventing that power line is dilatory and stressed, easy to operate, standard construction temporary electricity, improved working security;
2, ground protection further improves the fail safe of equipment electricity consumption.
3 and this construction power supply case need move time, hold pull bar casing tilted, by universal wheel, rolls power supply box integral body is moved ahead, drag laborsaving, facilitate.
4, drum moves with casing, is convenient to cable drag and drop, effectively increases work efficiency.
5, set up binding post, improve the flexibility of using.
