AI Technical Summary
Traditional dustproof net support structures have poor stability, are difficult to withstand wind, have inflexible height and width adjustments, and are cumbersome to expand, which affects the dustproof effect and increases construction costs.
The support structure employs telescopic columns and buffer springs, combined with cross-distributed fixed rods and adjustable guide rings to enhance the stability of the support; the dustproof net is secured by a double fixing method to ensure tension, and the height and width of the support can be flexibly adjusted; the modular expansion method is simple and maintains structural stability.
It improves the structural stability and impact resistance of the support structure, ensures that the dustproof net is always taut, is flexible in adjustment, and is easy to expand, thus reducing the cost and difficulty of dustproof construction.
