Description

Technical Field

[0001] The utility model relates to the technical field of power distribution boxes, in particular to a small mobile and portable power box. Background Art

[0002] Portable small power boxes are compact and easy to carry and move, and are usually used in temporary construction sites, exhibitions, and event venues to meet temporary power supply needs. Rollers are usually provided at the bottom of the small power box to meet the needs of flexible transfer and improve the convenience of its movement and replacement. In order to ensure the stability of the small power box during use, self-locking universal wheels are usually installed at the four corners of the bottom of the small power box. Although the self-locking universal wheels have the dual functions of being movable and positionable, when positioning, there is still a certain degree of instability due to the arc-shaped surface where the bottom of the universal wheel contacts the ground, which poses a potential safety hazard.

[0003] Based on the above problems, the patent with publication number CN218678097U discloses a portable power distribution box, including a box member and a mobile member. The box member includes a distribution box body, and the bottom of the distribution box body is fixedly connected with two left-right symmetrical and L-shaped support plates; the mobile member includes two concave frames that are respectively rotatably connected to the left and right sides of the bottom of the distribution box body and are in a vertical direction, and the bottoms of the two concave frames are rotatably installed with two universal wheels that are symmetrical in front and back and used to support the distribution box body. The utility model can realize the flexible switching between the universal wheel and the support plate, thereby ensuring the stability of the box when in use; however, this structure still has the following problems, that is, the structure is relatively complex, and when the state of the universal wheel is adjusted, an external power supply is required to power the motor. In order to match the corresponding structure, a certain use space of the distribution box will be sacrificed or the volume of the distribution box will be increased to meet the design requirements. However, the excessive volume and the installation of too many structures are contrary to the portable design concept, which brings inconvenience to use and movement. Utility Model Content
