The invention discloses a learning table with an automatic overturning table board which solves the problem of low stability and reliability of the table board during overturning. In order to solve the problem, according to the technical scheme, the table frame, the table board installed on the table frame and table legs used for supporting the table frame are mainly involved; the front end of thetable board is hinged to the table frame, the lower portion of the table board is provided with a power push rod and a mounting sleeve, the power push rod is sleeved with the mounting sleeve fixed tothe table frame, an overturning board fixed to the back surface of the table board is arranged above the mounting sleeve, the front end of the overturning board is connected to the mounting sleeve through a first rotating shaft, a connecting rod is hinged to the overturning board and connected with the power push rod through a second rotating shaft, and the power push rod drives the overturning board to rotate around the first rotating shaft through the connecting rod to make the table board overturned relatively to the table frame; the mounting sleeve is internally provided with a guide groove which inclines and extends upwards from the back side to the front side, and the second rotating shaft slides along the two opposite side walls of the guide groove. The second rotating shaft is restricted to floating up and down by the guide groove from the two sides, and the stability of the table board is high.

The invention discloses an omni-directional camera hoisting structure for tourist hotel monitoring, and relates to the technical field of camera hoisting structures. The omni-directional camera hoisting structure for tourist hotel monitoring comprises a fixed shell body and a control box which is fixedly connected to the inner wall of the bottom of one end of the fixed shell body, a controller is arranged in the control box, an operation panel is arranged at the top of the control box, a driving shaft is rotatably connected to the inner wall of one end of the fixed shell body, a driving belt wheel fixedly sleeves the driving shaft, a rotating shaft is fixedly connected to the inner wall of the other end of the fixed shell body, a tensioning belt wheel rotatably sleeves the rotating shaft, a fixed shaft is fixedly connected to the inner wall of the vertex angle of the fixed shell body, and the fixed shaft is rotationally sleeved with a guide belt wheel. The omni-directional camera hoisting structure for tourist hotel monitoring is reasonable in structure, operation can be carried out on a camera on the ground without climbing to a high position by using a ladder when the camera is installed, maintained and debugged, and therefore potential safety hazards caused by climbing to the high position are avoided.

The invention discloses a molding tool for dancing shoe sequins, which includes a main shaft, a first fixing plate, a second fixing plate, a third fixing plate, a first pressure column and a second pressure column, wherein the first fixing plate, the second fixing plate and the third fixing plate are set on the main shaft sequentially from top to bottom; the second fixing plate is formed with a plurality of forming holes; The number of pressing columns and the upper through holes is the same and they pass through the upper through holes in one-to-one correspondence. The third fixing plate is provided with lower through holes corresponding to the number of forming holes and corresponding in position one to one. The second pressing columns and the lower through holes are The number is the same, and a plurality of second pressure pillars pass through the lower through hole and are embedded in the forming hole one by one. Both the lower opening of the upper through hole and the upper opening of the lower through hole are connected with annular spacer sleeves, and both the first pressure column and the second pressure column pass through the spacer sleeves. When the invention is applied, dust can be prevented from entering the gap between the fixed plate and the pressure column to affect the normal movement of the pressure column, thus ensuring the sheet-forming efficiency of raw materials.

The invention belongs to the technical field of carton sheet pushing, and in particular relates to a carton sheet up-dial pushing device used in the packaging field, which includes a geared motor, an adjustment mechanism, a paper storage case, a paper feeding roller, a guiding telescopic plate, a transmission mechanism, a bottom plate, and a stopper. Cardboard, paper licking roller, the push outlet of the push device designed in the present invention is located on the upper side of the paper storage case, so that after each push of a carton piece, the pushed out carton piece will not be affected by other carton pieces, and the push resistance is small The carton sheet pushing device designed by the present invention adds a paper feed roller in the process of pushing the carton sheet, so that the length of the carton sheet only needs to be greater than the distance between the bottommost side of the paper feed roller and the pressure roller, In this way, the highest point that the paper licking roller can move can be relatively increased, and when the carton pieces are first placed in the paper storage case, the number of carton pieces in the paper storage case can be increased, so that the use efficiency of the device becomes high.
