2results about How to "Fast folding" patented technology

The utility model discloses a handle folding device of shopping bag, including frame, push folding plate mechanism, lifting platform mechanism, still be equipped with telescopic template on the lifting platform mechanism, still be equipped with the lower folding mechanism above push folding plate mechanism, lower folding mechanism including bracket, left folding plate, right folding plate, driving part, left folding plate and right folding plate are connected on horizontal driving part respectively, left folding plate and right folding plate with the left and right sides of telescopic template correspond, still be equipped with the pressing plate above between left folding plate and right folding plate, still be connected with the translation assembly and lifting assembly on the bracket. The utility model integrates the rear pressing plate, pressing plate mechanism, pressure folding mechanism of prior art into a simple lower folding mechanism, so that the whole machine structure is simple and compact, the lower folding mechanism of the utility model does not affect the normal conveying work of mechanical hand structure, and the folding speed is fast and the efficiency is high.

The utility model provides a kind of three-dimensional compression bag 1, 4, comprising: sealed cavity: by top layer 51, 61, bottom layer 52, 62 and peripheral surface layer 53, or symmetrical side layer 63A, 63B are enclosed and sealed connection formation;Wherein, the peripheral surface layer 53 is sequentially arranged between the top layer 51 and the bottom layer 52 around;Or the side layer 63A, 63B is symmetrically distributed in the top layer 61 and the bottom layer 62 two sides, the top layer 61 extends to the bottom layer 62 around connection;Peripheral surface layer 53 in the utility model is sequentially constituted with a surface layer material, so when sealing assembly is arranged in peripheral surface layer 53, air-tight zipper 2 can be arranged in at least two sides, so that air compression bag opening is more open, and it is convenient for user to take and place article.
