The invisible fan blade fixing structure and the invisible fan light provided by the embodiments of the present invention will be described in detail below through specific embodiments and application scenarios with reference to accompanying drawings 1 to 4 .

Referring to FIG. 1 , the invisible fan blade fixing structure disclosed in the embodiment of the present invention includes a turntable 100 , a synchronization member 200 and at least two fan blades 300 . The turntable 100 is connected with the driving source as the active part in the fixed structure. The rotation of the turntable 100 drives the fan blade 300 to rotate, and the rotation of the fan blade 300 then drives the synchronization member 200 to rotate.

The fan blade 300 has a free end and a mounting end, and both the turntable 100 and the synchronizing member 200 are movably connected to the mounting end of the fan blade 300 so that all the fan blades 300 can be synchronously switched between the stored state and the unfolded state.

The installation end of the fan blade 300 has a first rotating connection part 310 and a second rotating connecting part 320, and the rotating disk 100 has a shaft connecting part 120, and the first rotating connecting part 310 fits in the shaft connecting part 120 to make the fan blade 300 rotate. Turntable 100.

The synchronous member 200 has a plurality of limiting grooves 220, and the second rotating connection part 320 fits in the limiting grooves 220. When the driving source drives the turntable 100 from a static state to a rotating state, the turntable 100 rotates to drive the blades 300 to rotate relative to the turntable 100. When rotating, the fan blade 300 rotates around the axis of the first rotating connection part 310 due to centrifugal force, and then the second rotating connecting part 320 is slidably fitted into the limiting groove 220. At this time, the fan blade 300 is switched from the storage state to the unfolded state .

When the turntable 100 stops rotating, under the action of the reset part, the fan blade The fan blade 300 rotates around the axis of the first rotating connection part 310 , and then the second rotating connecting part 320 slides in the limiting groove 220 . At this time, the fan blade 300 is switched from the deployed state to the stored state. The reset member can be a spring, torsion spring or elastic rubber, and it only needs to realize the storage and reset of the fan blade 300 when the turntable 100 is stopped.

There is a limiting structure between the turntable 100 and the synchronizing member 200 , and when the fan blade 300 is in an unfolded state, the limiting structure can limit the rotation of the fan blade 300 .

The limiting structure includes a first limiting hole 110 and a second limiting hole 210. The first limiting hole 110 is set on the turntable 100, and the second limiting hole 210 is set on the synchronization member 200. When the fan blade 300 is in In the deployed state, the first limiting hole 110 corresponds to the second limiting hole 210 .

The hole walls of a limiting hole 110 are opposed to each other to limit the relative rotation between the synchronous part 200 and the turntable 100, so that the fan blade 300 cannot be automatically retracted and switched to the storage state, and the fan blade 300 is always kept in the unfolded state, which is convenient for fan blade 300 for cleaning.

When the first limiting hole 110 is a blind hole, the bottom end of the auxiliary part is located in the first limiting hole 110, and the auxiliary part will not be in contact with other parts of the invisible fan light when it is inserted and limited, preventing the invisible fan Other parts of the lamp were scratched.

As a better choice, the opening size of the second limiting hole 210 is smaller than or equal to the opening size of the first limiting hole 110, so that the auxiliary parts inserted into the second limiting hole 210 can be inserted into the first limiting hole in sequence. Inside the hole 110.

The first limiting hole 110 is a waist-shaped hole extending along the circumference of the turntable 100, the second limiting hole 210 is a round hole, relative rotation will occur between the turntable 100 and the synchronizing member 200, and the first limiting hole 110 is a waist-shaped hole. hole, so that the auxiliary member passing through the second limiting hole 210 can be easily inserted into the first limiting hole 110 . The first limiting hole 110 may also be a round hole or a square hole, and the specific shape of the first limiting hole 110 is not limited in this embodiment.

The auxiliary part is a rod-shaped structure, and the auxiliary part is loosely matched with the second limiting hole 210 so that the auxiliary part can pass through the second limiting hole 210 smoothly. Specifically, the auxiliary parts can be household items such as chopsticks and screwdrivers with a rod-shaped structure, without specific tools, which is convenient for users to clean the fan blade 300 by themselves, and has strong practicability.

In another optional embodiment, the synchronization member 200 is located below the turntable 100 , and the opening size of the first limiting hole 110 is smaller than or equal to the opening size of the second limiting hole 210 .

The number of the first limiting hole 110 is one, and the number of the second limiting hole 210 is the same as that of the first limiting hole 110. When fixing the fan blade 300, only the auxiliary parts need to be inserted into the first limiting hole at the same time. It only needs to be inside the positioning hole 110 and the second limiting hole 210 .

The number of the first limiting holes 110 is at least two, and all the first limiting holes 110 are evenly distributed along the circumference of the turntable 100; the number of the second limiting holes 210 matches the number of the first limiting holes 110, and all The second limiting holes 210 are evenly distributed along the circumference of the synchronization member 200;

The first limiting holes 110 are symmetrically distributed on the turntable 100, and the second limiting holes 210 are symmetrically distributed on the synchronization part 200.
