Description

Technical Field

[0001] The utility model relates to the technical field of electric boxes, in particular to a temporary electric box used on construction sites. Background Art

[0002] An electrical box is an electrical device used in power engineering, which contains multiple circuit protectors, circuit breakers, grounding circuits and other electrical equipment.

[0003] The electrical box can distribute electrical energy from the power supply to different circuits to meet the power needs of various equipment and power consumption in the building. It can also provide circuit protection, such as short circuit protection, overload protection and grounding protection, to ensure the safe and reliable operation of circuits and electrical equipment.

[0004] Temporary distribution boxes need to be installed at various construction sites to meet power needs. Currently, the distribution boxes are generally fixed, but as the construction progresses, the position of the distribution boxes needs to be adjusted to adapt, and it is inconvenient to move the distribution boxes. At the same time, facing different construction scenarios, the installation height of the distribution boxes is also inconsistent. Based on this, the utility model proposes a temporary distribution box for construction sites that can solve the above problems. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a temporary power box for construction sites, comprising a pad and a shell box, wherein the shell box is arranged on the pad through a guide assembly, and lifting rods are respectively hinged on both sides of the shell box, and two sets of pulleys are arranged on the lifting rods, and the two sets of pulleys form a gap for the wire body to pass through;

[0007] The guide assembly includes a frame connected to the pad, a top rod screwed to the pad, and a supporting rod connected to the shell box. There are multiple groups of supporting rods, and the multiple groups of supporting rods extend vertically downward and penetrate the frame. A supporting part for lifting the shell box is provided on the top of the top rod.

[0008] As a preferred technical solution, moving wheels are installed at the bottom of the pad.

[0009] As a preferred technical solution, the support portion includes a disc body connected to the top plate, a slot is provided at the bottom of the shell box, and the disc body is rotatably engaged with the slot.

[0010] As a preferred technical solution, a plurality of balls are respectively arranged at the upper and lower ends of the disc body.

[0011] As a preferred technical solution, a cover body is arranged on the top of the shell lifting box, and the outer diameter of the cover body gradually increases from top to bottom.

[0012] As a preferred technical solution, pulling assemblies are respectively provided on both sides of the shell box, and the pulling assemblies include a spring and a bolt rod connected to the shell box, and a pull rope connected to the lifting rod. The spring extends and is connected to the lifting rod, and the pull rope can be wrapped around the bolt rod to adjust the angle between the lifting rod and the shell box.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The movable wheels are provided to facilitate the movement and adjustment of the position of the temporary power box. The box can be moved upward or downward by rotating the top rod. The support part lifts the shell box on the top rod. When the top rod is vertically displaced, the shell box can be moved synchronously. The height of the shell box can be adjusted according to the construction scene of the construction site.

[0015] The wires of the electrical equipment can pass through the gap formed along the two sets of pulleys, which can provide auxiliary support for the wires and prevent them from falling directly downward, thus effectively improving safety.

[0016] After the position and height of the temporary electric box are adjusted, two adjacent groups of clamping strips are connected by magnetic attraction, and four groups of spacers are connected to form a cover body, which can block water and rain, and has a water-blocking effect on the shell box, preventing water from entering the shell box from the top;

[0017] When the height of the shell box is low, the wire body is supported and lifted by keeping the lifting rod and the shell box at a large angle to the shell box, thereby preventing the wire body from being accidentally touched due to its low height. BRIEF DESCRIPTION OF THE DRAWINGS
