The utility model provides a foldable filter screen and a filter module, and belongs to the technical field of filter equipment. The folding connecting pieces are located between the two corresponding adjacent filter screen main bodies, and the folding connecting pieces are fixed to the side edges of the two adjacent filter screen main bodies, so that the two adjacent filter screen main bodies are connected with each other; the folding connecting piece is made of a flexible material, so that the relative angle change between two adjacent filter screen main bodies can be realized through the deformation of the folding connecting piece, and the folding or unfolding action of the filter screen main bodies is completed; the folding filter screen has the advantages that by adopting the folding connecting pieces made of flexible materials, the angles of the adjacent filter screen main bodies can be freely changed, so that the whole filter screen has excellent folding performance, space is conveniently saved during transportation and storage, and meanwhile, the folding filter screen can be quickly unfolded and kept in a stable structural form during use.

The utility model provides a folding chair which comprises a folding frame provided with a first matching part and a second matching part; the chair body is connected with the folding frame; the sunshade mechanism comprises a first supporting rib, a second supporting rib, a first connecting piece, a second connecting piece and a sunshade piece; the two ends of the first supporting rib are connected with the two first connecting pieces correspondingly, and the first connecting pieces are connected with the first matching part. The two ends of the second supporting rib are connected with the two second connecting pieces correspondingly, and the second connecting pieces are matched with the second matching parts. The sunshade piece is arranged between the first supporting rib and the second supporting rib; the first supporting rib and the second supporting rib are of an arch structure. The folding chair solves the problem of insufficient sunshade surface of the folding chair in the prior art.

The invention relates to an integrated folding multifunctional table which comprises a combined table board, connecting rods, a seat board and supporting legs, the combined table board comprises two half table boards, the opposite sides of the two half table boards are provided with first folded edges, the bottoms of the two half table boards are hinged, the tops of the connecting rods are correspondingly hinged to the bottoms of the half table boards, and the bottoms of the two half table boards are hinged to the connecting rods; the two seat plates are hinged to the lower end of the connecting rod, the supporting legs are correspondingly hinged to the side ends of the seat plates, and the supporting legs are hinged to the side ends of the seat plates; through the design of the integrated folding multifunctional table, the foldability, multifunctionality, stability and portability of the table top are achieved, through the synergistic effect of the combined table plate, the connecting rods, the seat plate, the supporting legs and other components, the table can provide a stable working or using platform when needed, and the table is convenient to use. And the multifunctional folding chair can be easily folded into a compact shape when not in use, is convenient to store and carry, and is suitable for occasions with limited space and need of frequent movement or multifunctional use, such as study travel and the like.
