Description

Technical Field

[0001] This utility model relates to the field of ceiling fans, specifically to ceiling head connectors and ceiling fans thereof. Background Technology

[0002] Existing ceiling fan structures such as Figure 1 and Figure 2 As shown, the device includes a suspension rod 10, a suspension head 2, a motor 11, and a motor cover 12. The upper end of the suspension rod 10 is mounted on the ceiling via a connector, and the lower end of the suspension rod 10 is mounted inside the upper end of the suspension head 2. The main shaft of the motor 11 is mounted inside the lower end of the suspension head 2, and fan blades are mounted on the main body of the motor 11. The suspension head 2 is provided with a first radial screw hole 6, in which a first locking screw 13 for locking the suspension rod 10 is screwed. The suspension head 2 is also provided with a second radial screw hole 8, in which a second locking screw 14 for locking the main shaft of the motor 11 is screwed. A mounting plate 3 is provided on the outer side of the lower end of the suspension head 2. The top of the motor cover 12 is fixedly mounted on the top of the mounting plate 3 by a fixing screw 16, and the lower end of the motor cover 12 covers the motor 11. The top of the motor cover 12 is provided with a mounting hole for the suspension head 2 to pass through.

[0003] During installation, the lifting head 2 is first fixedly mounted on the main shaft of the motor 11 using locking screws. Then, the motor cover 12 is passed through the lifting head 2 and placed on the motor 11. Finally, the motor cover 12 is fixed to the mounting plate 3 using fixing screws 16. For ease of installation and aesthetics, a countersunk hole 21 is machined at the outer end of the second radial screw hole 8, allowing the head of the second locking screw 14 to be recessed into the countersunk hole 21. This prevents the head of the second locking screw 21 from protruding from the outer wall of the lifting head 2, thus avoiding interference with the installation of the motor cover 12. However, machining the countersunk hole 21 on the lifting head 2 not only increases the number of processing steps and the processing difficulty but also raises the processing cost.
