Abstract: An easy-to-fold and easy-to-assemble box includes a left panel, a right panel, a front frame, a rear frame, a bottom panel and a top cover. The left panel and the right panel are both formed by connecting two or more sideboards through rotatable connectors. A rotatable connection end of the bottom panel is connected to a lower part of the rear frame through a rotatable connector. A movable end of the bottom panel braces against the front frame. An inner side of each of the two ends of the rear frame is provided with a vertical edge strip. One end of each of the left panel and the right panel is connected to the vertical edge strip through a rotatable connector, and the other end is connected to the front frame. The top cover is connected to the front frame through a connector.

Abstract: A foldable and expandable pet carrier bag. The foldable and expandable pet carrier bag includes a pet carrier bag body, the pet carrier bag body is provided with a first pet door, the pet carrier bag body has a back part, the back part is provided with a foldable expanding part. The expanding part includes a top wall, a bottom wall, a left side wall, a right side wall and a front side wall. The left side wall and the right side wall are folded toward the inner portion of the expanding part, respectively. The bottom wall and the front side wall that overlapped on the surface of the bottom wall are swung and overlapped on the top wall. The pet carrier bag is easy to fold, after being folded, the bottom wall of the expanding part fixed on the pet carrier bag body forms a back cushion.

Abstract: Present invention provides a pet carrying bag utilizing first tie bands and second tie band to provide means for securing the bag to a bicycle handle bar when looping the bands around the handle bar and clicking the insertion prongs to the receiving insertion shells. Such installation mechanism allows for tight and secure fit to bicycle handle bars of different configurations. The bag body is made of flexible materials with rigid back board and bottom board embedded inside the flexible material, for easy fold-down and storage. During regular usage, two movable boards can be set, by using common Velcro pieces, to prop the bag open, creating a maximum space for the pets.

Abstract: A pet house or a pet crate is easily collapsible, foldable and portable, having four side walls, connected to a roof plate, with a frame support built to the edges of the left and right side walls, when two first zippers zip up along the left and right side walls' edges to form the complete and assembled pet crate. A special 180-degree flip of a second zipper strip is made to the portion along the edges of the roof plate, so that the orientation of the zipper teeth at the portion connected to the roof plate is reversed in direction to the portion connected to the front and back side walls, providing a stronger propping power for the corners under the roof plate, when zipped up and fully erected.

Abstract: A building block, comprises a plurality of basic units and a plurality of connectors. Each connector is used to connect each two basic units. The basic unit is a hexahedron. Each face is set with a plurality of connecting holes and a slot. The connector inserts into one connecting hole on one face of the basic unit, and comes out from another connecting hole on the opposing face through the slot to connect with another basic unit. The connecting design not only increases the ways of connecting each two basic units, but also ensures that one basic unit has at least one connecting hole for connecting with another basic unit. The present invention is help to cultivate children's ability of multiple perspectives thinking and ability of 3D space thinking.
