At this time, the construction of the stage is very important. The stage needs to be assembled in different activity venues. There are many parts and the steps are cumbersome. Moreover, the height cannot be adjusted during use and cannot adapt to the venue requirements. Utility Model Content
[0003] The utility model provides an adjustable portable folding stage to overcome at least one defect of the prior art. The adjustable portable folding stage can adjust the height of the stage by changing the coordination of the height adjustment feet and the supporting legs. At the same time, the side brackets and the stage board can be folded by folding the folding arms, which reduces the occupied space and is convenient to carry and store.
[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: an adjustable portable folding stage, comprising a stage board, a side bracket for supporting the stage board, and a height-adjusting foot for adjusting the height of the side bracket, wherein the side bracket is pivotally connected to the stage board, and also comprises a folding arm whose two ends are pivotally connected to the stage board and the side bracket respectively, the folding arm folds and contracts when the side bracket is folded relative to the stage board, and unfolds and supports when the side bracket is unfolded relative to the stage board, the height-adjusting foot is provided with an adjustment hole, the side bracket comprises a supporting leg with a limiting hole connected to the height-adjusting foot, a plurality of the adjustment holes and / or the limiting holes are provided in the height direction, and a connecting pin passes through the adjustment hole and the limiting hole to lock the cooperation between the height-adjusting foot and the supporting leg.
[0005] The height-adjusting foot on the portable folding stage is provided with the limiting hole, and the supporting leg on the side bracket is provided with the limiting hole. A plurality of the adjusting holes and / or the limiting holes are provided in the height direction, and a connecting pin passes through the adjusting hole and the limiting hole to realize the locking of the height-adjusting foot and the supporting leg, and the cooperation between different adjusting holes and / or the limiting holes can adjust the height of the side bracket, thereby realizing the height adjustment of the stage; the portable folding stage is also provided with a folding arm, and the two ends of the folding arm are respectively pivotally connected to the stage board and the side bracket, one end of the folding arm pulls the stage board, and the other end of the folding arm pulls the side bracket, and the folding or unfolding of the folding arm can realize the folding or unfolding of the stage board and the side bracket.
[0006] Furthermore, the distance between two adjacent adjustment holes is kept consistent, and the height adjustment foot adjusts the height of the side bracket by cooperating with the limit hole and the adjustment holes of different heights. The distance between the two adjustment holes is kept consistent, which can ensure the equal distance adjustment of the adjustment hole and the limit hole, realize the equal height adjustment of the side bracket, and also make the height adjusted by the multiple height adjustment feet consistent.
