Then, the fan blades are installed by tightening screws. This installation process not only requires each hole to be aligned, but also requires screws to be screwed into each hole. The installation process is cumbersome, and the disassembly process is also time-consuming and laborious. Utility Model Content

[0003] This utility model provides a fan blade mounting structure and a lamp fan having the same, aiming to solve the technical problems of existing fan blade mounting structures, which all rely on screw tightening, resulting in a cumbersome installation process and time-consuming and labor-intensive disassembly.

[0004] In a first aspect, embodiments of the present invention provide a fan blade mounting structure, comprising:

[0005] Fixed base;

[0006] The blade has slots and sockets;

[0007] The first snap-fit ​​assembly includes a rotating shaft, a rotating component rotatably connected to the fixed base via the rotating shaft, and a snap hook protruding from the bottom of the rotating component, the snap hook being used to engage with the slot;

[0008] The second snap-fit ​​assembly includes a plug that moves up and down, the plug being used to engage with the socket;

[0009] A first elastic element, connected to the rotating element, has a preload force that causes the hook to extend into the slot;

[0010] The second elastic element, connected to the plug, has a preload force that causes the plug to extend into the socket.

[0011] In conjunction with the first aspect, in one possible implementation, the fixed base is provided with two supporting parts, the top surface of the supporting parts is recessed to form a support groove, the two ends of the rotating shaft are rotatably engaged with the two support grooves, and the outer periphery of the middle part of the rotating shaft protrudes to form a limiting ring, the limiting ring being located between the two supporting parts.

[0012] In conjunction with the first aspect, in one possible implementation, the first elastic element is a torsion spring, which is sleeved on one end of the rotating shaft and located at the shaft end of the limiting ring. One fixing rod of the torsion spring abuts against the fixing seat, and the other fixing rod is connected to the rotating element.

[0013] In conjunction with the first aspect, in one possible implementation, the second snap-fit ​​assembly includes a cover plate detachably connected to the fixing base, the cover plate having a first sliding groove, the plug fitting slidingly engaging with the first sliding groove, and the cover plate also having an encapsulation portion adapted to the rotating shaft, the encapsulation portion covering the top of the rotating shaft.

[0014] In conjunction with the first aspect, in one possible implementation, a housing is fixedly attached to the cover plate, the housing encloses and forms the first downward-opening groove, the plug is slidably connected to the housing, and the second elastic member is disposed inside the housing.

[0015] In conjunction with the first aspect, in one possible implementation, the second elastic element is a spring, and the outer periphery of the connector and the inner wall of the housing are respectively provided with abutment rings, and the two ends of the spring abut against the two abutment rings respectively.

[0016] In conjunction with the first aspect, in one possible implementation, the outer periphery of the housing is provided with a second slide groove communicating with the first slide groove, and a snap-fit ​​groove located on one side of the second slide groove and communicating with the second slide groove. The bottom wall of the snap-fit ​​groove is higher than the bottom wall of the second slide groove to form an overlapping platform. The top end of the plug is provided with a protruding rod, which has a first state of sliding in the second slide groove and a second state of being placed on the overlapping platform.

[0017] In conjunction with the first aspect, in one possible implementation, the overlapping platform has a limiting protrusion protruding on the side near the second slide groove, the limiting protrusion being used to prevent the protruding rod from sliding off the overlapping platform.

[0018] In conjunction with the first aspect, in one possible implementation, the top of the rotating member is provided with a lever.

[0019] Compared with the prior art, the solution shown in this application allows the blades to be inserted directly towards the mounting base during installation.

[0039] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0040] Please refer to the following: Figures 1 to 5 The installation structure of the fan blade provided by this utility model will now be described. The installation structure of the fan blade includes a fixed base 20, a blade 30, a first snap-fit ​​assembly 40, a second snap-fit ​​assembly 50, a first elastic element 60, and a second elastic element 70. The blade 30 has a slot 31 and an insertion hole 32. The first snap-fit ​​assembly 40 includes a rotating shaft 41, a rotating element 42 rotatably connected to the fixed base 20 via the rotating shaft 41, and a hook 43 protruding from the bottom of the rotating element 42, which is used to engage with the slot 31. The second snap-fit ​​assembly 50 includes a vertically movable insertion element 51, which is used to engage with the insertion hole 32. The first elastic element 60 is connected to the rotating element 42 and has a pre-tightening force to allow the hook 43 to extend into the slot 31. The second elastic element 70 is connected to the insertion element 51 and has a pre-tightening force to allow the insertion element 51 to extend into the insertion hole 32.

[0041] Compared with the prior art, the fan blade installation structure provided in this embodiment allows the blade 30 to be directly inserted towards the fixing base 20 during installation. During insertion, the pre-tightening force of the first elastic element 60 and the second elastic element 70 is overcome, causing the hook 43 to engage with the slot 31 and the connector 51 to engage with the insertion hole 32, thus fixing the fan blade. When the fan blade needs to be disassembled, the connector 51 and hook 43 need to be lifted manually, and then the blade 30 can be pulled out. In this invention's fan blade installation structure, the first snap-fit ​​component 40 and the second snap-fit ​​component 50 do not require frequent disassembly, and the pre-tightening of the first elastic element 60 and the second elastic element 70 enables automatic snap-fit ​​of the fan blade, simplifying the disassembly and assembly process, saving time, and reducing the labor intensity of installers.

[0042] In some embodiments, an improved implementation of the aforementioned fixing base 20 may employ, as follows: Figure 1 The structure shown. See also Figure 1 The fixed base 20 is provided with two supporting parts. The top surface of the supporting parts is recessed to form a support groove 21. The two ends of the rotating shaft 41 are rotatably engaged with the two support grooves 21. The outer periphery of the middle part of the rotating shaft 41 protrudes to form a limiting ring 44, which is located between the two supporting parts. The rotating shaft 41 engages with the two support grooves 21. The limiting ring 44 on the rotating shaft 41 can prevent the rotating shaft 41 from causing the rotating part 42 to slide off-axis along its axis, thus limiting the installation position of the rotating part 42 and ensuring that the hook 43 can always correspond to the position of the slot 31 during the frequent rotation of the rotating part 42.

[0043] In some embodiments, a specific implementation of the first elastic member 60 described above may employ, as follows: Figure 3 The structure shown. See also Figure 3 The first elastic element 60 is a torsion spring, which is sleeved on one end of the rotating shaft 41 and located at the shaft end of the limiting ring 44. One fixing rod of the torsion spring abuts against the fixing seat 20, and the other fixing rod is connected to the rotating element 42. The torsion spring has good endurance and a long service life, which can adapt to the frequent disassembly and assembly of the blade 30, and can maintain a stable elastic effect to ensure that the hook 43 is continuously inserted into the slot 31, thus ensuring the safety of the fan blade.

[0044] As a variation of the implementation, the first elastic element 60 can also be a spring. After the fixed seat 20 is installed on the turntable 10, a top cover needs to be installed on the top of the turntable 10. The spring can be connected between the rotating element 42 and the top cover. When the hook 43 rotates upward, it is lifted. At this time, the spring is compressed and the fan blade can be inserted. Then the spring rebounds and drives the rotating element 42 to rotate downward, and the hook 43 is engaged in the slot 31.

[0045] In some embodiments, an improved implementation of the second snap-fit ​​component 50 described above may employ, as follows: Figure 1 , Figure 2 and Figure 4 The structure shown. See also Figure 1 , Figure 2 and Figure 4 The second snap-fit ​​assembly 50 includes a cover plate 52 detachably connected to the fixing base 20. The cover plate 52 has a first sliding groove 55, and the plug-in 51 is slidably fitted into the first sliding groove 55. The cover plate 52 also has an encapsulation part 53 adapted to the rotating shaft 41, and the encapsulation part 53 covers the top of the rotating shaft 41. The cover plate 52 on the second snap-fit ​​assembly 50 can restrict the rotating shaft 41 at the top, preventing the rotating shaft 41 from popping out due to misalignment of the torsion spring, and ensuring that the rotation process of the rotating shaft 41 is not affected. When the cover plate 52 on the second snap-fit ​​assembly 50 is installed, it simultaneously limits the rotation of the rotating shaft 41, simplifies the installation steps, and has strong overall integrity.

[0046] Optionally, the cover plate 52 can be connected to the mounting base 20 via a threaded connector.

[0047] In some embodiments, an improved implementation of the cover plate 52 may employ, as follows: Figure 2 and Figure 5 The structure shown. See also Figure 2 and Figure 5 A housing 54 is fixedly attached to the cover plate 52. The housing 54 forms a downward-opening first sliding groove 55. The connector 51 is slidably connected to the housing 54, and the second elastic member 70 is disposed inside the housing 54. If the housing 54 is not provided, the thickness of the cover plate 52 needs to meet the length of the first sliding groove 55 to ensure that the connector 51 can slide inside. In this embodiment, the overall thickness of the cover plate 52 is relatively high, more material is used, and the cost is correspondingly increased. By providing the housing 54 to form the first sliding groove 55, the thickness of the cover plate 52 can be reduced accordingly, and the overall weight of the cover plate 52 is also reduced, which reduces the cost and facilitates installation.

[0048] In some embodiments, a specific implementation of the second elastic member 70 described above may employ, as follows: Figure 5 The structure shown. See also Figure 5 The second elastic element 70 is a spring. Abutment rings 58 protrude from the outer periphery of the connector 51 and the inner wall of the outer shell 54, respectively. The two ends of the spring abut against the two abutment rings 58. The spring is sleeved on the outer periphery of the connector 51. When the connector 51 slides upward, the distance between the two abutment rings 58 decreases, and the spring is compressed. When the connector 51 aligns with the insertion hole 32, the spring rebounds, and the connector 51 is inserted into the insertion hole 32.

[0049] As a variation, the second elastic element 70 can also be a rubber block, which abuts against the top wall inside the housing 54 and the plug 51, compressing the rubber block when the plug 51 slides upward.

[0050] In some embodiments, an improved implementation of the above-described connector 51 and hook 43 can be as follows: Figures 3 to 5 The structure shown. See also Figures 3 to 5 Both the bottom of the connector 51 and the bottom of the hook 43 are provided with guide slopes 80. When the blade 30 is inserted, the end of the blade 30 directly abuts against the guide slope 80, thereby driving the rotating part 42 to rotate under the action of thrust, and at the same time driving the connector 51 to move upward, making the installation faster and easier.

[0051] In some embodiments, an improved implementation of the housing 54 described above may employ, as follows: Figure 2 , Figure 4 and Figure 5 The structure shown. See also Figure 2 , Figure 4 and Figure 5The outer periphery of the outer casing 54 is provided with a second slide groove 56 communicating with the first slide groove 55, and a snap-fit ​​groove 57 located on one side of the second slide groove 56 and communicating with the second slide groove 56. The bottom wall of the snap-fit ​​groove 57 is higher than the bottom wall of the second slide groove 56 to form an overlapping platform. The top of the plug-in 51 is provided with a protruding rod 59. The protruding rod 59 has a first state of sliding in the second slide groove 56 and a second state of being placed on the overlapping platform. When it is necessary to disassemble the fan blade, lift the protruding rod 59 to the position of the snap-fit ​​groove 57, rotate the protruding rod 59 to the overlapping platform, and the overlapping platform prevents the plug-in 51 from sliding down. At this time, the plug-in 51 is positioned, and the fan blade can be pulled out by directly lifting the rotating part 42, avoiding the inconvenience of simultaneously lifting the plug-in 51 and the rotating part 42.

[0052] Specifically, a lever 45 is provided on the top of the rotating component 42. By pushing the lever 45, the rotating component 42 can be lifted, which facilitates operation.

[0053] In some embodiments, an improved implementation of the above-described splicing platform may employ, as follows: Figure 2 , Figure 4 and Figure 5 The structure shown. See also Figure 2 , Figure 4 and Figure 5 A limiting protrusion 510 protrudes from the side of the overlapping platform near the second slide groove 56. The limiting protrusion 510 is used to prevent the protruding rod 59 from sliding out of the overlapping platform. After the protruding rod 59 overlaps on the overlapping platform, the limiting protrusion 510 and one side wall of the locking groove 57 limit the protruding rod 59, preventing the protruding rod 59 from rotating out of the locking groove 57 due to shaking when disassembling the fan blade.

[0054] Based on the same inventive concept, this application also provides a lamp fan, including a turntable 10 and a plurality of mounting structures for the aforementioned fan blades, wherein the fixing seat 20 in the mounting structure of each fan blade is integrally formed with the turntable 10, and the mounting structures for the plurality of fan blades are evenly distributed around the axial direction of the turntable 10.

[0055] It should be noted that the above-mentioned fan blade mounting structure can also be used in ordinary fans, not just light fans.

[0056] Compared with the prior art, the lamp fan provided in this embodiment has a fixed base 20, a first snap-fit ​​component 40, and a second snap-fit ​​component 50 all installed inside a turntable 10. The outer wall of the turntable 10 is provided with multiple blade mounting slots that correspond one-to-one with the mounting structures of multiple fan blades. The blades 30 extend into the turntable 10 through the blade mounting slots and are simultaneously snapped into the first snap-fit ​​component 40 and the second snap-fit ​​component 50 inside the turntable 10 to complete the installation. This installation structure not only improves the installation strength of the blades 30 and enhances the safety of the lamp fan, but also realizes the automatic snap-fit ​​of the fan blades, simplifies the disassembly and assembly process, saves disassembly and assembly time, and reduces the labor intensity of the installers.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
