Fixing device with flanged purline and photovoltaic module supporting structure

The invention provides a fixing device for a purline with an edgefold, which comprises a purline supporting plate, a fastening assembly and a purline supporting fastener, and the purline supporting fastener locks the purline with the edgefold on the purline supporting plate through the fastening assembly. The machining mode, the fixing mode and the stress mode of the purline with the folded edge are optimized, the purline with the folded edge does not need to be fixed by machining strip-shaped holes, the machining period is shortened, the overall stress area is large, and installation is more stable; and meanwhile, the height of the purline with the folded edge is flexible and adjustable, so that the rotating angle is increased, and more complex project environments can be coped with. 本发明提供了一种带折边檩条的固定装置，包括檩托板、紧固组件、和檩托扣件，所述檩托扣件通过紧固组件将带折边檩条锁紧于檩托板上。本发明从带折边檩条的加工方式、固定方式、受力方式几个方面进行优化，带折边檩条不需要通过加工条形孔来完成固定，缩短加工周期，整体受力面积大，安装更加稳固；同时带折边檩条的高度灵活可调，进而增加了转动角度，能应对更加复杂的项目环境。
