The invention discloses a corrugated paper corner armor used for a flat product, wherein the corrugated paper corner armor is arranged at each of four feet of the flat product, the corrugated paper corner armor consists of a corrugated paper base and a corrugated paper clamp seat, and the corrugated paper clamp seat is arranged on the corrugated paper base. The corrugated paper corner armor used for the flat product is convenient to prepare, avoids pollution, is easy to recover, is convenient to store and deliver, and is low in package cost.

The invention provides a switchgear with high heat dissipation efficiency, which includes a box body and a cyclone cooling device, the side of the box body is hinged with a box door, the bottom of the box body is slidably connected with a fixed plate, and the fixed plate is connected with a box matching the box body. The cover plate, the fixed plate is provided with a first ventilation pipe, the bottom of the first ventilation pipe is connected with an air guide pipe, the box body is provided with an air inlet pipe connected with the air guide pipe, and the inside of the first ventilation pipe is connected with a ventilation pipe. The fan and the cyclone cooling device are fixed above the first ventilation duct. The cyclone cooling device includes an outer cylinder, a second ventilation duct and an air guide tube. The air guide tube is arranged inside the outer cylinder, and the second ventilation duct communicates with the outer tube. , The outer cylinder, the second ventilation duct and the air guide tube are provided with cavities, the cavities are equipped with cooling liquid, and the box body is provided with a number of air outlets. The invention can evenly disperse and blow the wind blown by the ventilation fan to the cabinet through the cyclone cooling device, so as to realize sufficient heat dissipation of the switch cabinet, and the temperature decreases when the wind passes through the cyclone cooling device, so as to achieve a good heat dissipation effect.

The invention discloses a packaging box with a folding and folding function, and relates to the technical field of packaging boxes. The device comprises a base, two side plates and two end plates, the base is connected with two strip-shaped plates, a first sliding groove and a second sliding groove are formed in the opposite faces of the two strip-shaped plates, and inserting grooves are formed in the inner bottom faces of the ends, away from each other, of the first sliding groove and the second sliding groove. The two side plates are hinged to the two strip-shaped plates correspondingly, and folding is achieved when the two side plates rotate oppositely. Rectangular blocks are connected to the lower portions of the opposite side walls of the end plates, the two end plates are slidably connected with the first sliding grooves and the second sliding grooves through the rectangular blocks correspondingly, and when the rectangular blocks are inserted into the inserting grooves, the end plates are kept in the vertical state, and the end plates, the base and the two side plates define a box structure. The two side plates are hinged to the strip-shaped plates, folding of the side plates is achieved, the rectangular blocks of the two end plates are matched with the first sliding grooves and the second sliding grooves, stacking of the two end plates in a horizontal state is achieved, and the problems that an existing packaging box cannot be folded thoroughly, and the occupied space is large are solved.
