[0026] Currently, with the improvement of people's living standards, more and more families choose to install ceiling fans in air-conditioned rooms to stir air circulation and solve the problem of uneven hot and cold air in air-conditioned rooms. However, for the ceiling fan lights on the market, their fan blades generally have a flat product shape, with little differentiation; moreover, due to the limitation of the fan blade size and length, the packaging volume and space are wasted significantly. Often, the fan blade is very long, but the utilization rate of the packaging space inside is low, resulting in high transportation costs and easy breakage.

[0027] Such as Figure 1 、 Figure 2 and Figure 3As shown in the figure, an embodiment of the utility model provides a splicing structure for a ceiling fan blade, which includes: a first blade 10, a second blade 20, and a fixing connector 30 fixedly connecting the first blade 10 and the second blade 20. The fixing connector 30 includes: a fixing upper cover 31 and a fixing base 32;

[0028] Wherein, one end of the first blade 10 and one end of the second blade 20 are spliced by mortise and tenon. The fixing upper cover 31 is located on the top surface of the splicing part, and the fixing base 32 is located on the bottom surface of the splicing part. At least one fixing screw sequentially passes through the fixing upper cover 31, the first blade 10 or the second blade 20 and then extends into the fixing base 32 for fixation. At least one fixing screw passes through the fixing upper cover 31 and the splicing part of the first blade 10 and the second blade 20 and then extends into the fixing base 32 for fixation. Then, the first blade 10 and the second blade 20 are fixedly connected through the mutual cooperation of the fixing upper cover 31 and the fixing base 32.

[0029] Adopting the above scheme, first of all, after the first blade 10 and the second blade 20 are spliced by mortise and tenon and then fixedly connected through the fixing connector 30, the present application splits a complete blade into the first blade 10 and the second blade 20. On the basis of reducing the size of a single blade, the packaging volume during transportation is reduced, the utilization rate of the packaging space is increased, and the transportation cost is reduced and it is not easy to be damaged. Secondly, at the splicing part of the first blade 10 and the second blade 20, the fixing upper cover 31 and the fixing base 32 are fixed by fixing screws, which not only fixedly connects the fixing upper cover 31 and the fixing lower part, but also prevents the first blade 10 and the second blade 20 from disengaging from each other, enhancing the firmness of the splicing between the first blade 10 and the second blade 20.

[0030] As Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 shown, in order to avoid the fixing screws from wearing the first blade 10 and the second blade 20, the top surface of the fixing base 32 is provided with fixing convex columns 321. The first blade 10 or the second blade 20, and the splicing part of the first blade 10 and the second blade 20 are provided with first fixing holes 11, 101, 201; The fixing convex columns 321 pass through the first fixing holes 11, 101, 201 and then abut against the bottom surface of the fixing upper cover 31. The fixing screws pass through the fixing upper cover 31 and then extend into the fixing convex columns 321 for fixation. The fixing convex columns 321 can separate the fixing screws from the first fixing holes 11, 101, 201, thereby avoiding the fixing screws from wearing the first fixing holes.

[0031] In order to firmly join the end of the first fan blade 10 and the end of the second fan blade 20 by mortise and tenon, the mortise and tenon joint adopts a dovetail structure; the part of the end of the first fan blade 10 protruding towards the end of the second fan blade 20 is in a "V" shape, and the recessed part of the end of the second fan blade 20 matches the protruding part of the first fan blade 10; the bottoms of the recessed parts on both sides of the protruding part of the end of the first fan blade 10 are inclined towards the second fan blade 20, and the inclination is parallel to the hypotenuse of the corresponding "V" shape. The protruding parts on both sides of the recessed part of the end of the second fan blade 20 match the shape of the recessed parts on both sides of the protruding part of the end of the first fan blade 10, so as to prevent the splicing parts from separating from each other after the first fan blade 10 and the second fan blade 20 are spliced together.

[0032] In order to reduce the width of the fixing connector 30, the fixing upper cover 31 and the fixing base 32 are in a "V" shape, and the fixing upper cover 31 and the fixing base 32 can cover the splicing part of the first fan blade 10 and the second fan blade 20, so as to minimize the width of the fixing connector 30 on the basis of being able to fix and connect, further reducing the cost of the spliceable structure of the ceiling fan blades and facilitating the popularization of ceiling fan lights.

[0033] In order to further prevent the splicing parts from separating from each other after the first fan blade 10 and the second fan blade 20 are spliced together, the first fixing holes 101 and 201 at the splicing part of the first fan blade 10 and the second fan blade 20 are arranged at one end of the splicing parts on both sides of the "V" - shaped splicing part of the first fan blade 10 and the second fan blade 20. The first fixing holes 101 and 201 are set at the corners. Furthermore, the fixing convex columns 321 are respectively clamped with the first fixing holes 101 and 201 of the first fan blade 10 and the second fan blade 20, making the clamping structure more firm.

[0034] In order to position the fixed upper cover 31 fixed to the fixed base 32, second fixing holes 102 and 202 are provided at the other ends of both sides of the joint where the first fan blade 10 and the second fan blade 20 are spliced in a "V" shape and at the tip of the joint where the first fan blade 10 and the second fan blade 20 are spliced in a "V" shape; a plurality of snap rivets 322 are provided on the top surface of the fixed base 32, and two communicating snap holes 311 and 312 are provided on the fixed upper cover 31 at positions corresponding to each of the snap rivets 322. The diameter of one of the two snap holes 311 and 312 is larger than the diameter of the snap rivet 322, and the diameter of the other of the two snap holes 311 and 312 is smaller than the diameter of the snap rivet 322; after a plurality of the snap rivets 322 sequentially pass through the corresponding second fixing holes 102 and 202 and one of the two snap holes 311 and 312 with a larger diameter, slide the fixed upper cover 31 so that the snap rivet 322 slides from one of the two snap holes 311 and 312 with a larger diameter into the other of the two snap holes 311 and 312 with a smaller diameter, so that the snap rivet 322 abuts against the upper surface of the fixed upper cover 31.

[0035] During use, when the snap rivet 322 slides from one of the two snap holes 311 and 312 with a larger diameter into the other of the two snap holes 311 and 312 with a smaller diameter, the fixing hole positions corresponding to the fixing screws on the fixed upper cover 31 are aligned with the fixing hole positions of the fixed convex posts 321, so as to facilitate fixing the fixed upper cover 31 to the fixed base 32.

[0036] In order to facilitate the installation of the fixed connecting member 30 and avoid the fixed connecting member 30 from wearing external objects, positioning protrusions 323 are provided at both ends of the fixed base 32, and positioning grooves 103 and 203 are provided on the first fan blade 10 and / or the second fan blade 20. After the positioning protrusions 323 are embedded in the positioning grooves 103 and 203, the position of the fixed upper cover 31 can be positioned, facilitating the installation of the fixed connecting member 30; the end surfaces of the positioning protrusions 323 are flush with the end surfaces of the first fan blade 10 and / or the second fan blade 20, avoiding the positioning protrusions 323 at both ends of the fixed base 32 from protruding from the end surfaces of the first fan blade 10 and / or the second fan blade 20, and avoiding the fixed connecting member 30 from wearing external objects.

[0037] The present utility model also provides a ceiling fan lamp, including the spliceable structure of the ceiling fan blades as described above.

[0038] The above has described the present utility model in detail with reference to the accompanying drawings, but the present utility model is not limited to the described embodiments. For those skilled in the art, without departing from the principles and spirit of the present invention, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present utility model.
