6results about How to "Improve foldability" patented technology

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.
