Description

Technical Field

[0001] This utility model belongs to the technical field of power signage, specifically relating to an adjustable power construction sign. Background Technology

[0002] During power construction, it is necessary to place power construction signs in front of the construction site to alert passing vehicles and pedestrians. In existing technology, power construction signs consist of an A-frame bracket and a title plate. When storing, the legs of the two A-frame brackets are brought together. However, this storage method still leaves a large space after storage, making it inconvenient to carry.

[0003] To address the above issues, a utility model patent with publication number CN222939606U discloses a power construction sign. The sign includes a nameplate, a support component on the back of the nameplate, a fixing component on the inner side of the support component, and an assembly component between the nameplate and the support component. The support component includes a connecting block, and two first support rods are rotatably connected to the inner side of the connecting block. The two first support rods on the inner side of the same connecting block are arranged in a V-shape, and the second support rods are on the same straight line as the first support rods.

[0004] The aforementioned power construction sign can be separated from the first and second fixed rods by unscrewing the bolts. After separation, the second support rod can be flipped forward by the hinge between the first and second support rods. By flipping the two second support rods outward and bringing them closer to the first support rod, the overall footprint after folding can be greatly reduced, making transportation and storage more convenient.

[0005] However, the length of the first horizontal bar is fixed and cannot be adjusted. Even when folded, it still occupies space. Furthermore, the lengths of the first and second support rods are also fixed, and their lengths remain fixed even when unfolded, resulting in low flexibility. Therefore, a highly flexible adjustable power construction sign needs to be designed. Utility Model Content
