[0024] In the related art, the installation of existing ceiling fan blades usually requires three or four screws to fix the blades on the blade frame, and then fix the blade frame on the turntable of the ceiling fan. The installation process of this blade structure is complicated, there is no predetermined blade position, and manual judgment of the point position is required to ensure the angle position of the blade after installation. Auxiliary tools are required, the operation is cumbersome, and it is not conducive to use.

[0025] For this purpose, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, which is a conveniently installed ceiling fan blade 200 structure proposed by the utility model, includes a turntable 100 and a blade 200, the turntable 100 includes a cylindrical mounting plate 120 and a connecting portion 110 for connecting to the output end of the ceiling fan, the mounting plate 120 is located at the bottom of the connecting portion 110 and is coaxially arranged with the connecting portion 110, the width of the mounting plate 120 is greater than the connecting portion 110, so as to form a mounting plate 121 between the mounting plate 120, the mounting plate 121 is annular, and a positioning step 130 is arranged along the circumferential direction, and a card groove 131 is arranged on the side wall of the positioning step 130. The fan blade 200 is connected to the turntable 100. The fan blade 200 includes a blade 210 and a mounting frame 220 connected to the blade 210. The mounting frame 220 is an unclosed annular structure, and a clamping table 230 is provided at one end thereof close to the blade 210. A plurality of fan blades 200 are stacked and mounted on the connecting portion 110, and rotate around the axis of the turntable 100 so that the clamping table 230 can be clamped in the clamping slot 131, so that the fan blade 200 is fixed to the turntable 100. It can be understood that during installation, the mounting frame 220 is passed through the upper part of the turntable 100, that is, it is mounted on the outer wall of the connecting portion 110, so that its bottom surface abuts against the mounting plate 121, and then the blade 210 is moved to drive the mounting frame 220 to rotate around the axis of the turntable 100, until the clamping table 230 is clamped in the clamping slot 131, and the pre-fixation of the fan blade 200 and the turntable 100 is completed. The installation operation steps of the ceiling fan blade 200 are significantly simplified, the installation difficulty is reduced, the installation efficiency is improved, and no auxiliary tools are required, which not only simplifies the installation process but also reduces the installation cost. Furthermore, through the cooperation of the precisely designed card platform 230 and the card slot 131, a stable connection can be formed between the blade 200 and the turntable 100, ensuring the stability and safety of the ceiling fan during operation. On the other hand, when the blade 200 needs to be replaced or repaired, the user only needs to reverse the operation and easily remove the blade 200 from the turntable 100 without the need for laborious disassembly or finding tools, which greatly saves time and energy, and also improves the efficiency of disassembly and assembly.

[0026] Reference Figure 1 , Figure 2 and Figure 3 The height of the mounting frame 220 is designed to gradually increase from the clamping table 230 toward the other end, forming a shape of a spirally encircling the connecting portion 110. When installing multiple blades 200, the blades 200 can be stacked layer by layer, and the height of the mounting frame 220 of each layer of blades 200 increases, thereby avoiding interference during the installation process, making the installation process smoother, not only avoiding interference during the installation process, but also improving the stability of the installation of the blades 200. At the same time, the setting of the spirally encircling connecting portion 110 also makes the blades 200 more balanced when rotating, reducing vibration and noise.

[0027] Reference Figure 2In some embodiments, the number of the fan blades 200 is 3, and the mounting plate 121 is provided with 3 positioning steps 130 with increasing heights step by step along the circumference. The card slots 131 on each positioning step 130 are evenly and equidistantly arranged along the circumference of the mounting plate 121 to correspond to the installation of the 3 fan blades 200. Further, the 3 fan blades 200 are stacked and mounted on the connecting portion 110, and each fan blade 200 corresponds to a positioning step 130 at a different height. When a fan blade 200 is installed on the positioning step 130, the height of the end of its mounting frame 220 away from the card platform 230 is exactly the same as the positioning step 130 of the next level, so as to facilitate the installation of the next fan blade 200. By providing 3 fan blades 200 and the corresponding 3 positioning steps 130, the wind force of the ceiling fan is more uniform, and the air circulation effect is improved. At the same time, the uniform distribution of the fan blades 200 and the positioning steps 130 also makes the appearance of the ceiling fan more beautiful. The stacking installation method not only saves space, but also makes the installation of the fan blades 200 more orderly. At the same time, the height design of the mounting frame 220 increasing layer by layer avoids interference between the fan blades 200, thereby improving the installation efficiency.

[0028] Reference Figure 1 and Figure 3 Specifically, in order to make the installation of the fan blade 200 smoother, the clamping platform 230 is provided with a guide slope 231 that is inclined downward toward the clamping slot 131. When installing the fan blade 200, the guide slope 231 can guide the clamping platform 230 to smoothly extend into the clamping slot 131. The guide slope 231 reduces the resistance during the installation process, and at the same time, it also improves the accuracy of the installation of the fan blade 200, avoiding safety hazards caused by improper installation.

[0029] Reference Figure 1 and Figure 4 The top of the positioning step 130 is provided with a limit snap-in 132 connected to the snap-in slot 131. When the card platform 230 is inserted into the snap-in slot 131, the upper part of the card platform 230 extends into the limit snap-in 132, and the side wall of the card platform 230 located near the upper part abuts against the inner side wall of the limit snap-in 132, thereby limiting the card platform 230 from being separated from the snap-in slot 131, further enhancing the connection stability between the fan blade 200 and the rotating disk 100. Even in the case of strong wind, the fan blade 200 is not easy to fall off, thereby improving the safety performance of the ceiling fan.

[0030] Reference Figure 1 and Figure 3 A clearance portion 232 is provided between the clamping platform 230 and the mounting frame 220. The height of the clearance portion 232 is not higher than the highest part of the clamping platform 230, so as to provide enough space for the clamping platform 230 to extend into the clamping slot 131 during the installation process, making the installation of the fan blade 200 more flexible and convenient. At the same time, due to the height restriction of the clearance portion 232, interference with other components during the installation process is also avoided.

[0031] Reference Figure 3 and Figure 4 The mounting frame 220 is provided with a through fixing hole 221, and the mounting plate 121 is correspondingly provided with a fixing groove 122. When installing the fan blade 200, a fastener (such as a screw) can be passed through the fixing hole 221 and inserted into the fixing groove 122, thereby reinforcing the connection between the fan blade 200 and the turntable 100. The fastener reinforcement further enhances the stability of the connection between the fan blade 200 and the turntable 100. Even in extreme conditions (such as excessive wind or vibration), the fan blade 200 is not easy to fall off or loosen, thereby improving the durability and safety of the ceiling fan.

[0032] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
