The ceiling fan blade structure includes: at least one fan blade provided with a first inserting portion; and a mounting plate provided with a second inserting portion, and being able to be detachably connected with the fan blade through a fit between the first inserting portion and the second inserting portion.
In the present solution, the installation way of the fan blade is changed, and the connecting members used in the existing mounting method of fan blades are removed. The fan blade is provided with the first inserting portion, the mounting plate is provided with the second inserting portion, and through corresponding insertion between the first inserting portion and the second inserting portion, the fan blade may be mounted to the mounting plate rapidly. Thus, the ceiling fan blade structure is low in number of parts and low in cost. Moreover, during mounting of the fan blade, a mounting operation can be completed without assistance of auxiliary tools, and the mounting operation is simple and takes a short time.
In the above technical solution, preferably, one of the first inserting portion and the second inserting portion includes a plurality of elastic snaps, and the other one thereof includes a plurality of snap grooves; the plurality of elastic snaps are able to be inserted into the plurality of snap grooves respectively and snap-fitted with the plurality of snap grooves respectively, so as to enable the fan blade to be detachably connected with the mounting plate.
In this solution, the detachable connection between the fan blade and the mounting plate is realized through the fit between the elastic snap and the snap groove. During the mounting, the elastic snap is inserted into the snap groove to be snap-fitted with the snap groove, so as to fix the fan blade to the mounting plate. Therefore, the fan blade can be mounted without assistance of auxiliary tools, and the mounting operation is simple and takes a short time.

In this solution, the elastic snaps are arranged opposite to each other, and when the fan blade and the mounting plate are mounted together, the two elastic snaps abut against the respective bottom walls and respective two side walls of the two snap grooves, so as to achieve the best fixing effect of the elastic snaps on the fan blade.
In any one of the above technical solutions, preferably, the mounting plate is provided with a plurality of second inserting portions equally spaced apart along a circumferential direction.
In this technical solution, the mounting plate is provided with the plurality of second inserting portions, and all fan blades of a ceiling fan are mounted to one mounting plate, such that the ceiling fan blade structure has a small number of parts, and production cost of a product is low. Since there is only one mounting plate, a mounting operation of the mounting plate and other parts of the ceiling fan is also simple, thereby improving assembly efficiency of the product.
In any one of the above technical solutions, preferably, the first inserting portion is provided with a first fixing hole; the second inserting portion is provided with a second fixing hole; when the first inserting portion is fitted and connected with the second inserting portion, the first fixing hole is aligned with the second fixing hole; the ceiling fan blade structure further includes a fixing member, and the fixing member is able to enter the first fixing hole and the second fixing hole and fix the first inserting portion to the second inserting portion.
In this solution, the fixing member serves as an insurance structure for mounting the fan blade, which improves reliability of the mounting between the fan blade and the mounting plate. The first inserting portion is provided with the first fixing hole, and the second inserting portion is provided with the second fixing hole. During the mounting of the fan blade, the first inserting portion is first fitted and connected with the second inserting portion, and then the fixing member is mounted to the first fixing hole and the second fixing hole, such that it is possible to avoid separation of the first inserting portion from the second inserting portion by a fit of the fixing member with the first fixing hole and the second fixing hole, thereby improving safety of the product. During dismounting of the fan blade, the fixing member is first detached, and then the first inserting portion is separated from the second inserting portion, thus the detachment of the fan blade is completed.
Preferably, one of the first fixing hole and the second fixing hole is provided in the position limiting block, the other one thereof is disposed in a wall of the position limiting groove, and the position limiting block is disposed between two snaps and located in a middle position of the first inserting portion or the second inserting portion, such that the fixing member fixes the middle portion of the first inserting portion or the second inserting portion, resulting in a good fixing effect and further improving the reliability of the mounting between the fan blade and the mounting plate.

In this solution, during mounting of the fixing pin, the first position limiting portion of the fixing pin passes through the first fixing hole and the second fixing hole, and then the fixing pin is rotated to enable one of the first position limiting portion and the second position limiting portion to abut against the edge of the first fixing hole, and enable the other one thereof to abut against the edge of the second fixing hole. In such a way, the fixing pin is effectively prevented from slipping off from the first fixing hole and the second fixing hole, thereby improving the safety of the product. A dismounting operation of the fixing pin is opposite to a mounting operation thereof, which will not be elaborated herein.
Specifically, an elastic fastening device may be mounted at the first fixing hole and/or the second fixing hole. The elastic fastening device is provided with a through hole that is aligned with the first fixing hole and the second fixing hole and has a width smaller than a width of the connecting portion of the fixing pin. During the mounting of the fixing pin, the elastic fastening device is pressed by the fixing pin and thus deformed elastically, such that the through hole is expanded, and the first position limiting portion and the connecting portion of the fixing pin may pass through the through hole. The elastic fastening device fastens the connecting portion of the fixing pin under the action of its resilient force, so as to avoid self-rotation of the fixing pin due to loosening, and prevent the fixing pin from slipping off from the first fixing hole and the second fixing hole, thereby reducing safety risk of the product.

Specifically, if the technical solution of realizing fixation by means of a fit of the screw and the nut is employed, after the screw is mounted, one of a head of the screw and the nut abuts against the fan blade, and the other one thereof abuts against the mounting plate. If the technical solution, in which at least one of the first fixing hole and the second fixing hole is configured as the threaded hole and the screw is screwed with the threaded hole, is adopted, after the screw is mounted, the head of the screw abuts against one of the fan blade and the mounting plate. A fixing hole in the other one of fan blade and the mounting plate must be configured as the threaded hole, such that the rod portion of the screw is screwed with the threaded hole.
