In order to increase the air volume and make the wind feel in a wider range, the length of the fan blades will be appropriately increased. If the fan blades are a whole piece, the packaging cost will inevitably increase. Moreover, now is the era of globalized trade. Long-distance and large-volume transportation will increase huge transportation costs for enterprises.

[0003] Based on this, a fan blade splicing structure is designed. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a fan blade splicing structure, which effectively solves the problems raised in the above background.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fan blade splicing structure, including a fan blade frame plate, wherein the first fan blade is distributed circumferentially on the upper end of the fan blade frame plate, the first fan blade and the fan blade frame plate are connected by screws, and the second fan blade is movably inserted into one side of the first fan blade.

[0006] Preferably, one end of the first fan blade is connected to a plug-in block, one end of the second fan blade is provided with a plug-in slot, and the plug-in block is plugged into the plug-in slot.

[0007] Preferably, a card block is connected to the lower end of the plug-in block, a card slot is provided at the lower end of the plug-in slot, and the card block is adapted to be card-connected with the card slot.

[0008] Preferably, one end of the card block is provided with a guiding slope for easy insertion.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The utility model divides a longer fan blade into two first fan blades and a second fan blade, adopts the connection between the plug-in block and the plug-in slot, and the cooperation between the card block and the card slot. The fan is packaged and transported in such a splicing manner, and is manually spliced ​​and installed by the user, which can effectively reduce the packaging and transportation costs, and the assembly is convenient and quick, and the operation is simple.

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] Embodiment 1, by Figure 1-Figure 4 The utility model comprises a blade frame 1, a first blade 2 is distributed circumferentially on the upper end of the blade frame 1, the first blade 2 is connected to the blade frame 1 by screws 3, and a second blade 4 is movably inserted on one side of the first blade 2;

[0020] One end of the first fan blade 2 is connected with a plug-in block 5, and one end of the second fan blade 4 is provided with a plug-in slot 6, and the plug-in block 5 is plugged into the plug-in slot 6, so that the first fan blade 2 and the second fan blade 4 are assembled into an integral long fan blade through the plug-in block 5 and the plug-in slot 6.

[0021] The lower end of the plug-in block 5 is connected with a card block 7, and the lower end of the plug-in slot 6 is provided with a card slot 8. The card block 7 and the card slot 8 are adapted and connected. Through the cooperation of the card block 7 and the card slot 8, the plug-in block 5 and the plug-in slot 6 can ensure that the second fan blade 4 does not shake after assembly, thereby enhancing the assembly stability;

[0022] One end of the card block 7 is provided with a guiding inclined surface 9 for easy insertion. When the card block 7 is inserted, the guiding inclined surface 9 can play a guiding role, making the plug-in convenient.

[0023] Working principle: During assembly, since there is a card block 7 on the plug-in block 5 of the first fan blade 2, and the second fan blade 4 has a corresponding plug-in slot 6 and card slot 8, the user only needs to align the plug-in block 5 with the plug-in slot 6 and insert it, and at the same time, the card block 7 is buckled into the card slot 8 to complete the entire fan blade splicing. The cooperation of the plug-in slot 6 and the card slot 8 can prevent the second fan blade 4 from shaking. This is both convenient and fast. After that, the spliced ​​fan blades are fixed to the fan blade frame plate 1 with screws 3, and the fan blades are extended.
