The invention discloses a mine mouth protective device used for a mine hoist. The mine mouth protective device comprises a mine, protective plates, a bottom plate, a hoisting device and a carrying box, the bottom plate is of a rectangular platy structure, the mine is arranged below the bottom plate, a rectangular mine mouth is formed in the center of the bottom plate and communicated with the mine, the hoisting device is arranged on the upper end face of the bottom plate through four sets of stand columns, the hoisting device is arranged above the mine mouth, the carrying box is arranged inside the mine, the protective plates are arranged at the top end of the mine and are of rectangular platy structures, a grid plate is arranged at the position, located on the mine mouth, of the bottom plate through the protective plates, and the hoisting device comprises the stand columns, a ceiling and a motor set, wherein the ceiling is arranged at the top ends of the four sets of stand columns. The mine mouth protective device used for the mine hoist is simple in structure, reasonable in design and high in safety, and the anti-slipping performance of the mine mouth is improved.

The invention discloses an inner barrel structure of a washing machine and a washing machine with the inner barrel. The inner barrel is coaxially arranged in an outer barrel of the washing machine; cleaning particles for cleaning the walls of the barrels are arranged between the inner barrel and the outer barrel; a flange plate is arranged at the bottom part of the inner barrel; the flange plate and a hollow area at the bottom part of the inner barrel form a permeable channel; a baffle cover for preventing the cleaning particles from entering into the inner barrel via the permeable channel is arranged between the bottom part of the inner barrel and the flange plate; a permeable hole is formed on the baffle cover corresponding to the permeable channel; the baffle cover is a hollow annular cover body; and a protruding main body at the centre of the flange plate correspondingly blocks a hollow position of the baffle cover, and the permeable hole is distributed at the position of the annular cover body corresponding to the permeable channel. According to the invention, the structure of the baffle cover is simple; the installation cost is low; the cleaning particles between the inner barrel and the outer barrel can be prevented from entering into the inner barrel, and the problem that the cleaning particles enter into the inner barrel to affect the barrel wall cleaning effect is avoided.

The invention discloses a flexible circuit board and a flexible circuit board connecting device. A flexible circuit board includes an FPC board, a reinforcement board is adhered to the upper surface of the interface end on the right side of the FPC board, and a front and rear panel is provided on the reinforcement board. A plurality of first through holes that are evenly distributed and run downward through the FPC board. The first through holes include a round hole and a through groove placed on both sides of the round hole to communicate with the two round holes. The connected cover frame and the placement frame, the FPC board is placed in the placement frame and is pressed tightly by the cover frame, there are gold fingers on the lower surface of the FPC board, a flexible circuit board connection device, including a body, which is composed of multiple terminals evenly distributed at the front and back , there is a buckle inside the terminal, the lower part of the buckle is a turntable, there is a third through hole on the terminal, the turntable is in the third through hole, and a push rod is included, the push rod passes through the third through holes of multiple terminals in turn, and the push rod It is connected with the turntable transmission in multiple terminals, and there are contact shrapnels on the terminals; the invention connects the FPC board and the body more tightly through the buckle connection, and will not slip off.
