Abstract: A protective cover structure includes a bottom plate, a coupling plate and a top lid. Two opposite edges of the coupling plate are respectively connected to the bottom plate and a top lid. The bottom plate, coupling plate and top lid are foldable with respect to one another. The bottom plate includes a first bottom board and second bottom board being foldable to each other. A buckling tongue for holding an electronic device is disposed on the first bottom board, and a covering element covering and positioning the electronic device is disposed on the second bottom board. An electronic device can be covered and positioned through the arrangement of the buckling tongue and covering element. When intending to operate the electronic device, a user lifts the top lid and folds and positions it under the bottom plate, or disengage the buckling tongue to release the electronic device, thereby supporting the electronic device in a standing-up use.

Abstract: A protective cover structure includes a main body with an accepting space to form a frame structure. A lid engages with the main body at the bottom of the frame through corresponding buckling elements. A groove is respectively disposed on the peripheries of upper and lower surfaces of the main body, where the groove of the lower surface is used for coupling and securing a decorative bottom plate, and the groove of the upper surface couples with an annular decorative body. In use, a user first removes the lid from the main body, inserts an electronic device, and then tightly covers the lid onto the main body, thereby securely receiving the electronic device in the main body to protect the electronic device, and providing decorative effects through the configurations of the decorative bottom plate and decorative body.

Abstract: A sealed packing box having a size checking space comprises a front portion and a rear portion abutting against and connecting with each other, the front portion is a transparent plastic housing, and the rear portion is a sheet member capable of abutting against and connecting with the front portion; the sealed packing box after being assembled has a first receiving space to completely seal a product packed, and a second receiving space as a size checking space to check whether a product packed is compatible with what one needs, the second receiving space has an access communicating with the outside. Thereby, a consumer can put an article in the second receiving space to check whether the volume of the product packed meets what he wants.
