NOVELTY - A new-type cover, square beautifying each corner of cover are fixed together through bolts by three connecting rods, the material of connecting rod is angle steel or glass steel composite material or graphene composite material; each side of the cube beautifying cover between the connecting rods of the two angle assembling connection piece, connecting piece whose two ends are respectively symmetrically provided with 4 screw holes, connected with the corresponding position on the stem is provided with a fixing hole. The size, screw hole passes through the two connecting fixing component for fixing fixing hole of the connecting rod. The utility model is assembled cover, compared with traditional beautifying cover, light weight, simple structure, convenient assembly, convenient to carry, is composed of three same structure are assembled according to different size beautifying cover fixed by bolt. when using the composite material fibre glass reinforced plastics or composite material of graphite, the weight of the whole can be greatly reduced on the basis of angle steel, and the strength is similar to angle iron, and it has simple structure and can greatly reduce cost.
