The invention relates to the field of installation of cross-flow fan blades, and provides a fan blade mounting structure and electrical equipment. The fan blade mounting structure comprises a cross-flow fan blade and a shell, wherein the cross-flow fan blade is provided with a first mounting shaft, a blade and a second mounting shaft which are sequentially distributed in the axial direction, the first mounting shaft is rotatably supported on the shell, and a connecting piece protruding out of the radial outer side is fixed to the peripheral wall of the second mounting shaft. The fan blade mounting structure is further provided with an end mounting base, the end mounting base is provided with a first half body and a second half body which are distributed in the first direction, the first half body is fixed to the shell, amounting hole which is through in the axial direction is defined by the first half body and the second half body, the first half body and the second half body are connected in an openable and closable mode, the second mounting shaft is arranged in the mounting hole in a penetrating mode, the second mounting shaft and the hole wall of the mounting hole are arranged in a spaced mode, the first direction is perpendicular to the axial direction, and the connecting piece is located on the side, away from the blades, of the end mounting base in the axial direction. The cross-flow fan blade is simple in structure and easy and convenient to disassemble and assemble.
Description
technical field [0001] The invention relates to the technical field of installation of cross-flow fan blades, in particular to a fan blade installation structure and electrical equipment. Background technique [0002] The Chinese invention patent application with the publication number CN108775627A discloses a bearing rubber ring assembly and an air conditioner with it. In this scheme, a fastener is fixed on the connecting shaft, and the fastener is used to connect with the motor, and the bearing rubber ring Avoidance holes are provided on the seat, so that the fasteners do not need to be removed when installing the connecting shaft, which is convenient for improving the assembly efficiency of the air conditioner. [0003] However, when this solution is used for the installation of cross-flow fan blades, on the one hand, since the fasteners and avoidance holes are both eccentrically arranged relative to the connecting shaft, when installing / dismounting the cooperation betwee...
