Description

Technical Field

[0001] This utility model relates to the field of fan blade installation, and in particular to a quick-installation structure for fan blades. Background Technology

[0002] An electric fan, also known as a fan or air blower, is a household appliance that uses an electric motor to drive fan blades to rotate, thereby accelerating air circulation. Electric fans are primarily used for cooling and air circulation. They are widely used in homes, classrooms, offices, shops, hospitals, and hotels. Common household electric fans are essentially axial flow fans, meaning the airflow is parallel to the axis of rotation of the fan blades. Ceiling fans, on the other hand, are fans that are fixedly installed on the ceiling. With the trend towards environmental protection and energy conservation, the use of high-power appliances like air conditioners is increasingly restricted. One air conditioner consumes the equivalent power of several ceiling fans. When the temperature does not exceed 30 degrees Celsius, using a fan is perfectly sufficient for cooling. Among all types of fans, ceiling fans produce the largest airflow and have the best cooling effect with the same amount of power.

[0003] However, traditional ceiling fans, such as the technical solution protected by the patent with application number CN201720818416.3, whose invention is entitled "Ceiling Fan", have cumbersome methods for installing and disassembling the fan blades, which affects the efficiency of installing and disassembling the ceiling fan. Utility Model Content

[0004] Therefore, it is necessary to provide a quick-installation structure for ceiling fan blades to address the technical problem that the traditional methods of installing and disassembling ceiling fan blades are cumbersome and affect the efficiency of ceiling fan installation and disassembly.

[0005] A fan blade quick-assembly structure includes: an annular receiving plate and a plurality of fan blade mechanisms; each of the fan blade mechanisms is evenly arranged circumferentially on the annular receiving plate;

[0006] The annular receiving plate contains a plurality of receiving boxes evenly arranged in a circle. The outer wall of the annular receiving plate has a plurality of insertion holes evenly arranged in a circle, each insertion hole corresponding to the opening end of one of the receiving boxes. A threaded through hole is provided in the middle area of ​​each receiving box, and an exposed opening is provided on one side of each receiving box. The annular receiving plate has a rotating threaded hole and a sliding opening next to each of the receiving boxes. An S-shaped spring plate is provided next to each of the receiving boxes on the annular receiving plate.

[0007] The fan blade mechanism includes a fan blade, a locking assembly, and a fixing assembly; a through hole is provided in the middle area of ​​the fan blade insertion end; the insertion end of the fan blade is adapted to the receiving box, and the insertion end of the fan blade passes through the insertion port and is inserted into the receiving box; a portion of the fan blade insertion end is exposed outside the exposed port; a limiting slot is provided on one side of the fan blade insertion end.

[0008] The locking assembly includes a rotating column, a first nut, a limiting plate, a connecting screw, a rotating sleeve, a locking block, a shifting column, and a driving plate. One end of the rotating column is provided with a threaded head, which is adapted to the rotating threaded hole. The threaded head is inserted into the rotating threaded hole and screwed onto the annular receiving plate. The first nut is adapted to the threaded head, is sleeved on the threaded head, and abuts against the annular receiving plate. The limiting plate is connected to the end of the rotating column away from the threaded head via the connecting screw. The rotating sleeve... The tube is adapted to the rotating column, the rotating sleeve is sleeved on the rotating column and rotatably connected to the rotating column; the locking block is connected to the outer wall of the rotating sleeve, the locking block is adapted to the limiting slot, and the locking block can be inserted into the limiting slot; the actuating column is connected to the locking block, the actuating column is adapted to the sliding port, the actuating column is inserted into the sliding port and slidably connected to the annular receiving plate; the driving plate is connected to the outer wall of the rotating sleeve, and the driving plate abuts against the movable end of the S-shaped spring plate;

[0009] The fixing component includes a screw and a second nut. The threaded hole and the through hole are adapted to the screw. The screw passes through the threaded hole and the through hole. The second nut is sleeved on the screw and screwed to the screw, connecting the insertion end of the fan blade to the receiving box.

[0010] In one embodiment, two limiting ports are provided on one side of the insertion port, and two limiting grooves are provided on the inner wall of the receiving box, each limiting groove communicating with a limiting port; the insertion end of the fan blade is provided with two limiting ridges, and both the limiting port and the limiting groove are adapted to the limiting ridges; each limiting ridge passes through a limiting port and is inserted into a limiting groove.

[0011] In one embodiment, the limiting ridge is integrally formed with the fan blade.

[0017] In one embodiment, the drive head of the screw has a drive groove.

[0018] In one embodiment, the drive groove is a cross-shaped groove.

[0019] During assembly, the fan blade quick-assembly structure involves inserting the fan blade through the insertion port into the receiving box. During this process, the insertion end of the fan blade abuts against the locking block, and the locking block drives the rotating sleeve to rotate around the rotating column. During rotation, the rotating sleeve compresses the movable end of the S-shaped spring plate via the driving plate. Once the insertion end of the fan blade is fully inserted into the receiving box, the S-shaped spring plate recovers its elastic deformation, driving the rotating sleeve to rotate via the driving plate. During rotation, the locking block is inserted into the limiting slot and engages with the insertion end of the fan blade. The screw is passed through the threaded through hole and the through hole, and the second nut is fitted onto the screw and screwed into it, thus connecting the insertion end of the fan blade to the receiving box. When disassembling the fan blade quick-assembly structure, the second nut is removed from the screw, and the screw is pulled out from the threaded through hole and the through hole. By turning the actuating column, the locking block is pulled out from the limiting slot, facilitating the removal of the fan blade from the receiving box. The aforementioned quick-installation fan blade structure facilitates the installation and removal of the fan blades, thereby improving the efficiency of ceiling fan installation and removal.
