[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] Please also read Figure 1 to Figure 2 , the fan blade 20 connection and installation structure provided by the utility model is now described. The fan blade 20 connection and installation structure includes a rotating seat 10, a plurality of fan blades 20 arranged in an annular interval around the rotation axis of the rotating seat 10, and a plurality of locking screws 30 corresponding to each fan blade 20. The rotating seat 10 has a plurality of installation positions 13 that can be defined and changed for each fan blade 20. The locking screw 30 can fix the corresponding installation position 13 to lock the corresponding fan blade 20 together with the installation position 13.

[0030] Compared with the prior art, the fan blade 20 connection and installation structure provided in this embodiment has a mounting position 13 located on the rotating seat 10 that can ensure the connection of the fan blade 20, and the variable mounting position 13 can be fixed under the action of the locking screw 30, and at the same time, the fan blade 20 has a limited effect, which can ensure the stability of the fan blade 20 after connection. Each fan blade 20 only needs one locking screw 30 to achieve the locking of the fan blade 20, and the structure is simple, easy to disassemble and assemble, and highly practical.

[0031] It should be noted that, with respect to the installation position 13, although the fan blade 20 can be limited, it can be changed, so the fixing of the installation position 13 by the locking screw 30 can be understood as making the installation position 13 no longer change.

[0032] In some embodiments, the rotating seat 10 may be used as follows: Figure 2 See the structure shown. Figure 2 The rotating seat 10 includes a rotating disk 11 and a plurality of pre-fixed components 12 .

[0033] Specifically, the turntable 11 has a plurality of lower contact portions, each of which is arranged in an annular interval around the axis of the turntable 11. Each pre-fixed component 12 is arranged in one-to-one correspondence with each lower contact portion, and each pre-fixed component 12 has an upper contact portion that can move relative to or opposite to the corresponding lower contact portion. The upper contact portion is provided with a limiting portion 124 that extends toward the lower contact portion and can be adapted to the limiting opening 22 provided on the fan blade 20. The limiting portion 124, the upper contact portion and the lower contact portion are enclosed to form a mounting position 13 that can be inserted into one end of the corresponding fan blade 20.

[0034] The rotating disk 11 can ensure rotation and also ensure power connection with the driving member.

[0035] The upper contact portion and the lower contact portion can clamp one end of the fan blade 20 to ensure a certain limiting effect.

[0036] The upper contact portion can move with the limiting portion 124, and the limiting portion 124 provided on the upper contact portion can be plugged into the limiting opening 22 provided on the fan blade 20 after the upper contact portion approaches the lower contact portion, so as to limit the fan blade 20. The mounting position 13 formed by the corresponding upper contact portion, the lower contact portion and the limiting portion 124 can ensure that one end of the fan blade 20 is inserted, and at the same time, the fan blade 20 can be clamped and fixed in position, so as to ensure the stability of the fan blade 20 after being locked.

[0037] In this embodiment, the rotating disk 11 can be directly connected to the driving member by power. The rotating disk 11 can also be rotatably connected to the fixing seat of the fan light and then connected to the driving member by power at the same time.

[0038] In addition, see Figure 1A compensation opening corresponding to the limiting portion 124 may be provided on the lower contact portion to prevent the limiting portion 124 from interfering with the lower contact portion after passing through the limiting opening 22 .

[0039] In some embodiments, the lower contact portion may be formed as follows: Figure 1 See the structure shown. Figure 1 The lower contact portion is tilted, and this structure can ensure that the fan blades 20 are tilted to ensure the air supply effect.

[0040] In some embodiments, the turntable 11 may be Figure 1 See the structure shown. Figure 1 The rotating disk 11 has a plurality of embedding grooves 111 with open tops, and the bottom surfaces of the embedding grooves 111 are lower contact portions. The side walls of the rotating disk 11 have a plurality of communication ports 112 that are connected to the embedding grooves 111 , respectively.

[0041] The embedding groove 111 can provide a lower contact portion to ensure that the fan blade 20 is clamped together with the upper contact portion. At the same time, the embedding groove 111 can ensure that the fan blade 20 is further limited in the extension direction of the lower contact portion, which can further improve the stability of the connection of the fan blade 20 and has a simple structure.

[0042] The communication opening 112 can ensure that the fan blade 20 is inserted into the embedding groove 111 outside the rotating disk 11 .

[0043] In this embodiment, regarding an implementation of the mounting groove 111, the turntable 11 may be a cylindrical structure with an accommodating cavity inside, and an annular platform is arranged in the accommodating space. The mounting groove 111 is arranged on the annular platform and contacts the inner wall of the accommodating cavity.

[0044] In some embodiments, the pre-fixing member 12 may be formed as follows: Figure 2 See the structure shown. Figure 2 Each pre-fixing component 12 includes a pressing plate 121 , two connecting members 122 and two springs 123 .

[0045] Specifically, the pressing plate 121 is arranged in parallel with the lower contact portion and spaced apart, and the end surface of the pressing plate 121 close to the lower contact portion is the upper contact portion. Two connecting members 122 are respectively arranged at both ends of the pressing plate 121, and each connecting member 122 is fixedly connected to the lower contact portion after passing through the pressing plate 121. Two springs 123 are respectively arranged on the two connecting members 122, and are both located between the pressing plate 121 and the lower contact portion. The two springs 123 can simultaneously bounce the pressing plate 121, so that the pressing plate 121 maintains a tendency to continuously move away from the lower contact portion.

[0046] Two connecting pieces 122 are respectively arranged at the two ends of the pressing plate 121, which can ensure that the pressing plate 121 can slide stably on the two connecting pieces 122, so as to smoothly approach the lower contact portion under the action of the locking screw 30. Two corresponding springs 123 are respectively arranged at the two ends of the pressing plate 121, which can ensure that the elastic force exerted on the pressing plate 121 is uniform, thereby ensuring the stable movement of the pressing plate 121.

[0047] When the locking screw 30 is not working, the two springs 123 bounce the pressure plate 121, so that the pressure plate 121 is away from the lower contact portion, which can ensure that one end of the fan blade 20 is smoothly inserted between the upper contact portion and the lower contact portion. After the fan blade 20 is inserted, the locking screw 30 works, driving the pressure plate 121 to approach the lower contact portion, and at the same time, the limiting portion 124 is inserted into the limiting opening 22 on the fan blade 20 to lock the fan blade 20 in the installation position 13. This structure can facilitate the disassembly and assembly of the fan blade 20, and at the same time, the limiting portion 124 connected to the pressure plate 121 can ensure that a limit is provided to the fan blade 20, ensuring the stability of the connection of the fan blade 20. Moreover, after the locking screw 30 is removed, the spring 123 bounces the pressure plate 121 away from the lower contact portion, so that the limiting portion 124 quickly breaks away from the limit on the fan blade 20, thereby ensuring the convenient placement and retrieval of the fan blade 20.

[0048] In some embodiments, the pre-fixing member 12 may be formed as follows: Figure 2 See the structure shown. Figure 2 The limiting portion 124 includes two inserted columns arranged at intervals, and the two inserted columns are integrally connected to the pressure plate 121. The setting of the two inserted columns can ensure the strength of the fan blade 20 and ensure the stability of the fan blade 20 after being limited.

[0049] In some embodiments, the pressing plate 121 may be Figure 1 , Figure 2 and Figure 3 See the structure shown. Figure 1 , Figure 2 and Figure 3 The pressing plate 121 is provided with a through hole for the locking screw 30 to pass through, and the lower contact portion is provided with a threaded hole threadedly connected to the locking screw 30. The fan blade 20 is provided with a through hole for the locking screw 30 to pass through.

[0050] In this embodiment, the locking screw 30 locks the pressure plate 121 in the lower contact portion and passes through the through hole on the fan blade 20 at the same time, and can be connected to the fan blade 20 at the same time, which can further ensure the stability of the connection of the fan blade 20.

[0051] In this embodiment, the via hole may be disposed between two pins.

[0052] In some embodiments, the connector 122 may be configured as follows: Figure 4 See the structure shown. Figure 4Each connecting member 122 includes a guide column 122a on which a spring 123 is sleeved and slidably connected to the pressure plate 121, a limiting cap 122b arranged at one end of the guide column 122a and in contact with the pressure plate 121, and a screw portion 122c located at the other end of the guide column 122a and threadedly connected to the lower contact portion.

[0053] The setting of the guide column 122a can ensure that the pressure plate 121 can move smoothly and facilitate the connection of the spring 123. The setting of the limit cap 122b can prevent the pressure plate 121 from being separated from the guide column 122a, and the screw part 122c can ensure a fixed connection with the lower contact part. Correspondingly, a screw hole for the screw part 122c to connect needs to be set on the lower contact part.

[0054] In some embodiments, the fan blades 20 may be Figure 3 See the structure shown. Figure 3 One end of the fan blade 20 is provided with a fan tooth 21 that is adapted to be connected to the mounting position 13. The fan tooth 21 can ensure that it is inserted into the mounting position 13. The size of the fan blade 20 may be large, so the fan tooth 21 can ensure the transition of the connection between the fan blade 20 and the mounting position 13, thereby facilitating the connection of the fan blade 20.

[0055] In this embodiment, the fan teeth 21 can be an integrally formed structure with the fan blades 20, and of course can also be an independent body connected to the fan blades 20 by bolts.

[0056] An embodiment of the present application also provides a fan light, including the above-mentioned fan blade 20 connection and installation structure.

[0057] The fan light provided in the embodiment of the present application is based on the same inventive concept as the above-mentioned fan blade 20 connection and installation structure, and therefore has all the technical effects of the above-mentioned fan blade 20 connection and installation structure, which will not be repeated here.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
