This utility model relates to the field of turnover box technology, and more particularly to a tobacco-specific raw tobacco leaf recycling turnover box, including components such as long side plates. Long and short side plates are alternately connected. Outer flaps are connected to the upper and lower sides of the long side plates, and inner flaps are connected to the upper and lower sides of the short side plates. The long side plates, short side plates, outer flaps, and inner flaps are integrally formed and assembled into a box body using folding and seamless welding techniques. A first connecting piece is symmetrically connected to one side of the inner flap, and a rotating disc is symmetrically rotatably connected to the outer flap. This utility model includes components such as a rotating disc, male and female hook and loop fasteners. When the turnover box is not full of tobacco and needs to be temporarily closed, the rotating disc can be rotated using the rotating components, thereby reducing the contact area between the male and female hook and loop fasteners. This achieves basic fixation, preventing debris from entering, and makes it easier to open when adding tobacco next time, thus considering practicality in different scenarios.

The utility model discloses a dust-proof industrial personal computer case convenient to disassemble and assemble, and particularly relates to the technical field of industrial personal computers, the dust-proof industrial personal computer case comprises an industrial personal computer case main body with an opening at the top, two sides of the industrial personal computer case main body are provided with dust-proof filter screens, and the top of the industrial personal computer case main body is provided with a pair of top plates; each top plate and the industrial personal computer case body are each provided with a rotating springback assembly, each rotating springback assembly comprises a pair of fixing blocks, the fixing blocks are fixedly connected to the outer surface of the industrial personal computer case body, rotating rods are rotationally connected to the fixing blocks, supporting blocks are fixedly connected to the rotating rods, the supporting blocks are fixedly connected to the top plates, the rotating rods are sleeved with torsional springs, and the torsional springs are fixedly connected to the supporting blocks. The two ends of the torsional spring are fixedly connected to the opposite faces of the fixing block and the supporting block correspondingly, and the two sides of each top plate are fixedly connected with positioning blocks correspondingly. According to the utility model, the technical problems that the industrial personal computer case needs to be disassembled and assembled with the help of a professional disassembling tool, and the use loss is easily caused due to the use of more fasteners are solved.

This application discloses a face cream jar, belonging to the field of cosmetic packaging. The face cream jar includes a bottle body and a cap screwed to the top of the bottle body. An inner cap is provided at the port of the bottle body. A through hole is provided on the cap for inserting the inner cap. An upper cap connected to the inner cap is hinged to the end of the cap away from the bottle body. An insert plate is fixedly connected to the side of the upper cap away from its hinge. Multiple first inclined plates are fixedly connected at equal intervals along the vertical direction on the inner side of the insert plate. A first groove for fitting the insert plate is provided on the cap body. Multiple second inclined plates for fitting the first inclined plates are fixedly connected at equal intervals along the vertical direction in the first groove. By providing a through hole in the cap body and hinged an upper cap connected to the inner cap, the structure is simple and easy to operate. It can quickly open and close the inner cap, and when closed, it can ensure the sealing and stability between the upper cap and the cap body, effectively preventing the face cream from being contaminated by the outside world and improving the user experience.

The zero-torsion rotating shaft device comprises a rotating shaft body, the rotating shaft body is sleeved with a torsion spring, one end of the torsion spring is fixedly installed on a rotating shaft of the rotating shaft body, and the other side of the torsion spring is pre-pressed on a sheet metal part of the rotating shaft body; the torsional spring provides initial torsion in the opening direction of the rotating shaft, and the initial torsion is equal to friction torsion of the rotating shaft, so that the rotating shaft does not need to overcome friction force in the opening process; the torsion spring provides residual torsion in the closing direction of the rotating shaft, and the residual torsion is used for providing descending resistance for a load connected with the rotating shaft. The rotary shaft has the advantages that the torsion spring is arranged in the hollow shaft part of the rotary shaft body, so that the occupation of external space is greatly reduced, and the light and thin design of electronic equipment is favorably realized.
