The utility model discloses a building outer wall waterproof structure relates to building waterproof technical field. The utility model discloses a mounting bracket, its top fixed mounting has with the roof eaves mouth concatenation's interface groove, and the pipeline is relatively communicated on the interface groove, and the cleaning plate is slidably arranged in the interface groove, and the moving assembly that the interface groove is equipped with drive cleaning plate reciprocating sliding along the length direction of interface groove, collection box, and it is communicated to set up with the pipeline, and the drain pipe is communicated on the collection box. The utility model drives the cleaning plate to arrange sundries to the pipeline automatically through the moving assembly, and the automatic cleaning function avoids the tedious of artificial periodic cleaning, improves the cleaning effect to the interface groove, prolongs the life of drainage system.

The invention relates to a waist bridge structure and an operating bed. The waist bridge structure comprises a rack; the driving assembly is arranged on the rack; the transmission assembly is rotatably arranged on the rack and is in transmission connection with the output end of the driving assembly; the output assembly comprises an arc-shaped rack, the arc-shaped rack is movably arranged on the rack and is in meshed connection with the transmission assembly, and the transmission assembly can drive one end of the arc-shaped rack to extend out of or move into the rack; and the waist bridge plate is connected to one end of the arc-shaped rack and moves along with the arc-shaped rack. Therefore, the transmission assembly is matched with the annular rack, so that enough thrust and movement stroke can be provided for the movement of the waist bridge plate, the accurate adjustment of the position of the waist bridge plate is realized, and the body position requirement of a specific operation is met. Meanwhile, the sizes of the transmission assembly and the arc-shaped rack are small, the overall size of the waist bridge structure can be reduced, the space occupied by the waist bridge structure in the operating bed is reduced, interference between the waist bridge structure and other components is avoided, and the use performance is guaranteed.

The utility model provides a slope tile feeding mechanism of a mahjong machine, and belongs to the field of mahjong machines. The mahjong tile feeding device comprises a mahjong tile feeding rail arranged between a mahjong tile feeding strip and a mahjong tile outlet channel, the mahjong tile feeding strip is rotationally connected to a mahjong machine, and the mahjong tile feeding rail is horizontally arranged. The tile feeding strip is connected with a rotation driving mechanism and can be driven by the rotation driving mechanism to rotate to an inclined state, so that one end of the tile feeding strip is adjacent to or in butt joint with one end of the tile feeding rail, and a tile pushing head is arranged on the tile feeding rail; the tile pushing head is connected with a rotation driving mechanism, the rotation driving mechanism can drive the tile pushing head to move in the axial direction of the tile feeding rail, the end, adjacent to the tile feeding strip, of the tile feeding rail is provided with an obliquely-arranged tile discharging inclined face, and the tile pushing head is provided with a tile pushing inclined face.
