EMBODIMENTS

Referring to FIG. 1 and FIG. 2, the present disclosure provides a ceiling fan blade quick assembly structure that includes a blade frame 1, a plurality of fan blades 2, and a plurality of tenon assemblies 3.

The blade frame 1 is fixedly installed on a motor, and the blade frame 1 is substantially in a shape of a circular frame, but the shape of the blade frame 1 is not limited thereto. The blade frame 1 includes a plurality of mounting portions 11, and a quantity of the mounting portions 11 is not limited and can vary according to a quantity of the fan blades 2. Each of the mounting portions 11 includes a bottom plate 111, a top plate 112, and a lateral slot 113 (as shown in FIG. 3 to FIG. 5). The top plate 112 is arranged at an interval above the bottom plate 111, the bottom plate 111 and the top plate 112 can be parallel to each other, and a side plate 116 can be connected between two sides of the bottom plate 111 and two sides of the top plate 112, such that the mounting portion 11 has a frame-shaped structure for having an increased structural strength. The lateral slot 113 is located between the bottom plate 111 and the top plate 112, and the bottom plate 111 and the top plate 112 are respectively located below and above the lateral slot 113. An insertion hole 114 is formed on the top plate 112, the insertion hole 114 may be a square hole, and the insertion hole 114 penetrates two sides of the top plate 112. A buckle hole 115 is formed on the bottom plate 111, the buckle hole 115 can be a square hole, and the buckle hole 115 penetrates two sides of the bottom plate 111. However, shapes of the insertion hole 114 and the buckle hole 115 are not limited thereto.

Each of the plurality of fan blades 2 has a blade body 21 and an assembly portion 22. The assembly portion 22 is connected to the blade body 21; that is, the assembly portion 22 is connected to one end of the blade body 21. The shape of the assembly portion 22 matches with that of the lateral slot 113, such that the assembly portion 22 can be inserted into the lateral slot 113. In this embodiment, the assembly portion 22 is a plate body having a cross-section that is quadrilateral-shaped, and the cross-section of the lateral slot 113 is also quadrilateral-shaped. Therefore, the assembly portion 22 and the lateral slot 113 can be inserted into each other and have a firm connection.

Each of the assembly portions 22 has a positioning groove 221 and a first elastic buckle 222. The positioning groove 221 corresponds to the insertion hole 114. The positioning groove 221 can be a square groove, and the positioning groove 221 can be tapered downward. A top side of the positioning groove 221 is open, such that one of the tenon assemblies 3 can be inserted into the positioning groove 221 from the top side. The first elastic buckle 222 is arranged on a bottom side of the assembly portion 22, and the first elastic buckle 222 corresponds to the buckle hole 115. The first elastic buckle 222 can have a first elastic arm 2221 and a first protrusion 2222, one end of the first elastic arm 2221 is a fixed end, and another end of the first elastic arm 2221 is a movable end. The first protrusion 2222 is located at the movable end of the first elastic arm 2221, and the first elastic buckle 222 can swing in a top-down manner to provide a buckle function, such that the first protrusion 2222 of the first elastic buckle 222 can be buckled with the buckle hole 115.

The assembly portions 22 of the plurality of fan blades 2 are respectively inserted into the lateral slots 113 of the mounting portions 11 of the blade frame 1 (as shown in FIG. 7 and FIG. 8). When one of the assembly portions 22 is inserted into the corresponding lateral slot 113, the first elastic buckle 222 can be buckled with the buckle hole 115 to prevent the assembly portion 22 from exiting out of the lateral slot 113, and the positioning groove 221 is aligned with the insertion hole 114 on the top plate 112.

The quantity of the tenon assemblies 3 can be changed according to the quantity of the fan blades 2. Each of the tenon assemblies 3 can be inserted into the insertion hole 114 and the positioning groove 221 when the assembly portion 22 of the fan blade 2 is inserted into the lateral slot 113, such that the assembly portion 22 of the fan blade 2 is stably mounted on the mounting portion 11 of the blade frame 1. In this embodiment, the tenon assemblies 3 can have a square body, and the tenon assemblies 3 can be tapered downward to match with the insertion holes 114 and the positioning grooves 221. Therefore, the tenon assemblies 3 can be smoothly inserted into the insertion holes 114 and the positioning slots 221. The tenon assemblies 3 can press on the first elastic buckle 222 (as shown in FIG. 5), such that the first elastic buckle 222 can be more stably buckled with the buckle hole 115, so as to prevent the assembly portion 22 from exiting out of the lateral slot 113.

A second elastic buckle 31 is provided on one side of the tenon assembly 3 (as shown in FIG. 6) for being engaged with a lower edge of one side of the insertion hole 114 when the tenon assembly 3 is inserted into the insertion hole 114 and the positioning groove 221, so as to prevent the tenon assembly 3 from exiting from the positioning groove 221 and the insertion hole 114 and achieve the purpose of tool-free quick installation. The second elastic buckle 31 has a second elastic arm 311, a second protrusion 312, and a pulling tab 313. One end of the second elastic arm 311 is a fixed end, and another end of the second elastic arm 311 is a movable end. The second protrusion 312 is located on the second elastic arm 311, the pulling tab 313 is located on the movable end of the second elastic arm 311, and the second elastic buckle 31 can swing in a front-rear manner. When the tenon assembly 3 is inserted into the insertion hole 114 and the positioning groove 221, the second protrusion 312 engages with the lower edge of one side of the insertion hole 114 to prevent the tenon assembly 3 from exiting from the positioning groove 221 and the insertion hole 114. The pulling tab 313 can be used to pull the second elastic buckle 31 to facilitate the disassembly of the tenon assembly 3.

In this embodiment, an upper end of each of the tenon assemblies 3 further has a flange 32. The flange 32 is arranged at a periphery of the upper end of the tenon assembly 3 and protrudes outward. When the tenon assembly 3 is inserted into the insertion hole 114 and the positioning groove 221, the flange 32 abuts against the top plate 112 of the mounting portion 11 to provide a blocking and positioning function, such that the tenon assembly 3 is positioned stably.

In addition, a plurality of elastic members 223 may be disposed on top or bottom sides of the assembly portion 22 of each of the fan blades 2. Each of the elastic members 223 has a third elastic arm 2231 and a third protrusion 2232. One end of the third elastic arm 2231 is a fixed end, and another end of the third elastic arm 2231 is a movable end. The third protrusion 2232 is located on the movable end of the third elastic arm 2231. The elastic member 223 can swing in a top-down manner to provide an elastic resistance function. When the assembly portion 22 is inserted into the lateral slot 113, the third protrusion 2232 of the elastic member 223 can abut against the top plate 112 or the bottom plate 111 (as shown in FIG. 7) to eliminate gaps between the assembly portion 22 and the lateral slot 113 in upper and lower directions.
