4results 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.

This application provides a folding buffer tray, including a top surface with an opening for receiving, and two side surfaces, a connecting surface, a supporting surface, and a snap-fit ​​surface connected sequentially on opposite sides of the top surface. A supporting surface is located on the side of the side surface away from the connecting surface. The snap-fit ​​surface has a first notch, and the supporting surface has a second notch. When folding the cardboard, the top surface, the side surface on one side of the top surface, and the supporting surface form a "U"-shaped frame. The snap-fit ​​surfaces fold towards the bottom of the "U"-shaped frame, the two snap-fit ​​surfaces overlap, and the first notch of the snap-fit ​​surface interlocks with the second notch of the supporting surface. The "U"-shaped frames formed on the two opposite sides of the top surface together constitute a cavity for receiving the bottle. The folding and enclosing mechanism using the side surfaces, connecting surface, supporting surface, and snap-fit ​​surface allows for fast folding; the interlocking of the first notch of the snap-fit ​​surface with the second notch of the supporting surface improves the stability of the bottle. This folding buffer tray is simple to fold, uses less material, and reduces costs.

The utility model relates to electric power overhauls equipment technical field, disclose overhauls platform, including hinge, platform body, support leg subassembly and support subassembly, platform body is two, hinge swing joint two platform body's side department, two platform body top surface has the unfolded state of being located in the same plane, and the folding state of each other's departure, be equipped with mounting hole on the platform body, support leg subassembly can be detachably installed in the mounting hole, support subassembly detachably connects platform body and photovoltaic support, the utility model discloses two platform body can be connected by hinge, can realize the unfolding and folding of overhauls platform fast, has the advantages that simple structure, convenient operation, the size of overhauls platform after folding reduces, is convenient for user to carry, connects platform body and photovoltaic support through support subassembly, avoids the overhauls platform to appear to shake when using, improves the stability when using.
