Problems solved by technology

[0003] However, when assembling each blade and each safety cable, the safety cable must be threaded from the first end of the blade, passed through the channel of the blade and then positioned at the second end of the blade, which is time-consuming and inconvenient
Especially for large-scale ceiling fans, in order to maintain a certain air volume when suitable for large-area spaces, the length of the blades of the large-scale ceiling fans is longer; it makes the assembly of each blade and each safety cable more time-consuming and labor-intensive, causing a lot of inconvenience in operation. It also leads to poor convenience and efficiency of overall assembly

Abstract

A ceiling fan blade is used for solving the problem that an existing ceiling fan blade is poor in assembly convenience. The blade body is provided with a near-axis end and a far-axis end which are opposite to each other; a channel extending from the proximal end to the distal end; and the through groove is positioned on the upper side or the lower side of the blade body, extends from the near-axisend to the far-axis end, and is communicated with the channel.

Description

technical field [0001] The invention relates to a wind driving device, in particular to a ceiling fan blade. Background technique [0002] Ceiling fans have been widely used by the public because they do not occupy ground space and have a good air disturbance effect. The existing ceiling fan has a shaft, a hub, a plurality of blades and a plurality of safety cables. The hub is rotatably combined with the shaft; the plurality of blades respectively have a first end and a second end, the first end is connected to the hub, and a channel communicates between the first end and the second end The plurality of safety cables are respectively arranged in the channel of each blade, one end of each safety cable is connected to the hub, and the other end of each safety cable is positioned at the second end of each blade. Thereby, when the existing ceiling fan rotates, each safety wire can be set through, so as to prevent the blade from breaking or detaching from the hub and falling to...
