[0003] In existing ceiling fans, one end of the fan blade is usually fastened to the blade fork base by bolts or screws. Since ceiling fans generally have more than two fan blades, and each fan blade has at least three bolts or screws to be fastened to the blade fork base, the connection between the fan blade and the blade fork base by bolts or screws is quite inconvenient for assembly and disassembly. Summary of the Invention

[0004] The main objective of this invention is to provide a ceiling fan blade mounting structure that improves the ease of installation and disassembly of the fan blades and blade fork base.

[0005] To achieve the above objectives, the present invention proposes a ceiling fan blade mounting structure, comprising:

[0006] A fork base, wherein the fork base is provided with at least one pin;

[0007] The fan blade has a insertion hole and at least one mounting hole, and the pin is inserted into the mounting hole; and

[0009] Preferably, the elastic buckle assembly includes:

[0010] The guide rail is fixedly connected to the blade fork base;

[0011] At least one latch, said latch being slidably engaged with said guide rail; and

[0012] At least one elastic element elastically abuts against the buckle, the buckle portion passing through the insertion hole and being held in place by the elastic abutment of the elastic element on the surface of the fan blade away from the blade fork base.

[0013] Preferably, the buckle includes a sliding part and a fastening part connected to each other, the guide rail is formed with a groove, the sliding part is accommodated in the groove, and the fastening part is engaged with the surface of the fan blade away from the blade fork base.

[0014] Preferably, the sliding part is inverted T-shaped, and the groove wall of the sliding groove is formed with a retaining edge that engages with the T-shaped step of the sliding part.

[0015] Preferably, the side of the fastening part is formed as a guide slope.

[0016] Preferably, there are two buckles, which are arranged opposite to each other. The elastic element is located between the two buckles, and both ends of the elastic element elastically abut against the two buckles respectively.

[0017] Preferably, the elastic element is a spring, and there are two elastic elements. The sliding part of each buckle is recessed with a mounting groove, and the bottom wall of the mounting groove is protruded with a connecting post. One end of each elastic element is accommodated in the mounting groove and sleeved on the connecting post.

[0018] Preferably, the blade fork base is provided with a fixing frame, the guide rail is housed within the space enclosed by the fixing frame, the blade fork base is provided with a screw hole, the guide rail is provided with a connecting hole, and the guide rail is fixedly connected to the blade fork base by screws engaging with the connecting hole and the screw hole.

[0019] Preferably, there are three pins, the number of mounting holes matches the number of pins, the three pins are arranged in an equilateral triangle, and the elastic buckle assembly is located at the center of the equilateral triangle.

[0020] The present invention also proposes a ceiling fan, including a ceiling fan blade mounting structure, wherein the ceiling fan blade mounting structure includes:

[0021] A fork base, wherein the fork base is provided with at least one pin;

[0022] The fan blade has a insertion hole and at least one mounting hole, and the pin is inserted into the mounting hole; and

[0023] An elastic snap-fit ​​assembly is fixedly connected to the blade fork base. The elastic snap-fit ​​assembly partially passes through the insertion hole and elastically snaps onto the surface of the fan blade facing away from the blade fork base.

[0024] This invention provides a flexible locking component on the blade fork base, in addition to a pin and mounting hole for interlocking between the blade and the blade fork base. The blade has an interlocking hole that mates with the flexible locking component.

[0037] This invention proposes a ceiling fan blade mounting structure 100.

[0038] Please refer to the reference. Figures 1 to 4 In one embodiment of the present invention, the ceiling fan blade mounting structure 100 includes a blade fork base 10, a fan blade 30, and an elastic buckle assembly 50. The blade fork base 10 is provided with at least one pin 11, and the fan blade 30 is provided with a insertion hole 31 and at least one mounting hole 33. The pin 11 is inserted into the mounting hole 33. The elastic buckle assembly 50 and the blade fork base 10 are fixedly connected. When the fan blade 30 is installed on the blade fork base 10, part of the elastic buckle assembly 50 passes through the insertion hole 31, and the part of the elastic buckle assembly 50 passing through the insertion hole 31 is elastically held on the surface of the fan blade 30 away from the blade fork base 10.

[0039] In actual installation, one end of the blade fork base 10 is fixedly connected to the ceiling fan via a motor-driven rotor, and the other end of the blade fork base 10 is clamped and fixed to the fan blades 30. The number of fan blades 30 is generally set to three or more, and these three or more fan blades are evenly spaced. Driven by the motor, the rotor drives the fan blades 30 to rotate around the rotor as the rotation center, thereby agitating indoor air and achieving indoor air convection. It is understood that the ceiling fan blade mounting structure 100 of this invention can be applied to ordinary ceiling fans, i.e., ceiling fans that drive indoor airflow, and can also be applied to ceiling fan lights that combine lights and ceiling fans for decorative functions. The fan blades 30 can be made of metal alloys, resulting in a stronger airflow. Alternatively, the fan blades 30 can be made of high-strength wood composite boards, and textured patterns can be formed on the surface of the fan blades, making them aesthetically pleasing and quieter during operation. The blade fork base 10 can be made of metal materials such as cast iron, produced by die casting. The surface of the blade fork base 10 can also be made of antique bronze, making the overall appearance of the ceiling fan more attractive.

[0040] The technical solution of this invention, based on the insertion and engagement of a pin 11 and a mounting hole 33 between the fan blade 30 and the blade fork base 10, also provides an elastic snap-fit ​​component 50 on the blade fork base 10, and an insertion hole 31 on the fan blade 30 that engages with the elastic snap-fit ​​component 50. When the fan blade 30 is installed on the blade fork base 10, the pin 11 is inserted into the mounting hole 33, and the elastic snap-fit ​​component 50 also partially passes through the insertion hole 31 and elastically holds the fan blade 30 on the surface away from the blade fork base 10. With the cooperation of the pin 11 and the mounting hole 33, and the elastic snap-fit ​​component 50 and the insertion hole 31, the fan blade 30 and the blade fork base 10 are securely connected. Compared with the existing method of connecting the fan blade 30 and the blade fork base 10 with multiple screws or bolts, this invention achieves an insertion and engagement between the fan blade 30 and the blade fork base 10, greatly improving the ease of assembly and disassembly of the fan blade 30 and the blade fork base 10.

[0041] In this embodiment, three pins 11 are provided, and the number of mounting holes 33 matches the number of pins 11. The three pins 11 are arranged in an equilateral triangle, with the elastic buckle assembly 50 located at the center of the equilateral triangle. Through this arrangement of the pins 11 and the elastic buckle assembly 50, the connection between the fan blades 30 and the blade fork base 10 is evenly stressed and the connection structure is secure during use of the ceiling fan. It is understood that the number of pins 11 can also be more than three, and the elastic buckle assembly 50 should be located at the center of the shape formed by the multiple pins 11.

[0042] Please refer to the reference. Figure 2 and Figure 3Specifically, the elastic buckle assembly 50 includes a guide rail 51, at least one buckle 53, and at least one elastic element 55. The guide rail 51 is fixedly connected to the blade fork base 10, the buckle 53 is slidably engaged with the guide rail 51, and the elastic element 55 elastically abuts against the buckle 53. When the fan blade 30 is installed on the blade fork base 10, part of the buckle 53 passes through the insertion hole 31. Under the elastic abutment of the elastic element 55, the part of the buckle 53 passing through the insertion hole 31 is held against the surface of the fan blade 30 away from the blade fork base 10.

[0043] When the fan blade 30 is installed on the blade fork base 10, the latch 53 slides linearly along the guide rail 51 as it passes through the insertion hole 31. After the latch 53 partially passes through the insertion hole 31, the elastic element 55 deforms under the action of the latch 53, generating an elastic force that reacts to the latch 53. The latch 53 then tends to return to its initial position (away from the center of the insertion hole 31) along the guide rail 51. This causes the portion of the latch 53 housed in the insertion hole 31 to elastically abut against the wall of the insertion hole 31, while the portion of the latch 53 that passes through the insertion hole 31 is firmly held on the surface of the fan blade 30 away from the blade fork base 10. In this embodiment, the elastic latch assembly 50, through the combination of the latch 53, the guide rail, and the elastic element 55, ensures a stable linear sliding process for the latch 53 to avoid misalignment as it passes through the insertion hole 31, making the insertion process of the fan blade 30 and the blade fork base 10 smoother.

[0044] Understandably, the structure of the elastic snap-fit ​​assembly 50 can also take other forms. For example, the elastic snap-fit ​​assembly 50 can be at least one metal hook-shaped member fixedly connected to the blade fork base 10. The metal hook-shaped member can be integrally formed with the blade fork base 10, or it can be fixedly connected to the blade fork base 10 by welding. During the process of installing the fan blade 30 onto the blade fork base 10, the metal hook-shaped member undergoes elastic deformation, bending towards the center of the insertion hole 31. After the hook-shaped part passes through the insertion hole 31, under the action of the elastic deformation of the metal hook-shaped member itself, the hook-shaped part of the metal hook-shaped member is engaged on the surface of the fan blade 30 away from the blade fork base 10, thereby achieving a fixed connection between the fan blade 30 and the blade fork base 10. In other embodiments, the elastic buckle assembly 50 may also be two metal hook-shaped pieces with two ends hinged to the blade fork base 10 and having a certain rotational capability. A torsion spring or compression spring is also provided between the two metal hook-shaped pieces. After the hook-shaped parts of the two metal hook-shaped pieces pass through the insertion hole 31, under the elastic force of the torsion spring or compression spring, the hook-shaped parts of the metal hook-shaped pieces are firmly locked onto the surface of the fan blade 30 away from the blade fork base 10.

[0045] Please refer to the reference. Figure 2 and Figure 3Specifically, in this embodiment, the buckle 53 includes a sliding part 531 and a fastening part 533 connected to each other. The guide rail 51 has a groove 511, and the sliding part 531 is accommodated in the groove 511. When the fan blade 30 is installed on the blade fork base 10, the fastening part 533 holds the fan blade 30 on the surface of the blade fork base 10 away from the blade fork base 10. In this embodiment, the guide rail 51 is formed by bending sheet metal or by die casting. The slide groove 511 extends through both ends of the guide rail 51 along its length. The buckle 53 is formed by the sliding part 531 and the engaging part 533 in an L-shape, with the sliding part 531 being an inverted T-shape. The groove wall of the slide groove 511 has a retaining edge (not shown) that engages with the T-shaped step of the sliding part 531. During the installation of the buckle 53, the buckle 53 can slide into the slide groove 511 through the opening at the end of the guide rail 51, making the installation process more convenient. After the buckle 53 is installed, the T-shaped structure of the slide groove 511 and the sliding part 531 cooperates to confine the sliding part 531 within the slide groove 511, making it less likely for the buckle 53 to detach from the slide groove 511, and the connection structure between the buckle 53 and the guide rail 51 is more stable.

[0046] It is understood that in other embodiments, the sliding part 531 may have a T-shaped groove 511, and the guide rail 51 may have a T-shaped cross-section, thus achieving a firm connection between the guide rail 51 and the buckle 53.

[0047] In order to ensure a smooth connection between the buckle 53 and the insertion hole 31, this embodiment forms a guide slope 5331 on the side of the buckle portion 533.

[0048] Furthermore, in this embodiment, two buckles 53 are provided, which are arranged opposite to each other. An elastic member 55 is located between the two buckles 53, and the two ends of the elastic member 55 elastically abut against the two buckles 53 respectively. In this embodiment, the projection of the fastening part 533 of each buckle 53 on the horizontal plane is approximately semi-circular. The two buckles 53 are arranged opposite to each other. During the process of the two buckles 53 passing through the insertion hole 31, the compression of the hole wall of the insertion hole 31 against the guide slope 5331 causes the two buckles 53 to slide closer to each other along the guide rail 51. After the fastening part 533 passes through the insertion hole 31, under the action of the elastic member 55, the two buckles 53 slide away from each other in the direction away from the center of the insertion hole 31. When the buckles 53 slide to the edge of the insertion hole 31, the fastening parts 533 of the two buckles 53 are respectively locked on the opposite sides of the insertion hole 31. Through the locking action of the two buckles 53, the connection structure between the fan blade 30 and the blade fork base 10 is relatively stable.

[0049] When there is only one buckle 53, the elastic member 55 can abut against the buckle 53 at one end and against the blade fork base 10 at the other end. This allows the buckle 53 to slide along the guide rail 51 and pass the fastening part 533 through the insertion hole 31. Under the elastic action of the elastic member 55, the buckle 53 slides along the guide rail 51 away from the center of the insertion hole 31, so that the fastening part 533 of the buckle 53 is engaged on the surface of the fan blade 30 away from the blade fork base 10.

[0050] In this embodiment, the elastic element 55 is a spring, and two springs are provided. The sliding part 531 of each buckle 53 is recessed with a mounting groove 5311, and the bottom wall of the mounting groove 5311 is protruding with a connecting post 5313. One end of each spring is accommodated in the mounting groove 5311 and sleeved on the connecting post 5313. In this embodiment, the spring is sleeved on the connecting post 5313, and the end of the spring is accommodated in the mounting groove 5311. During the spring compression deformation and spring elastic return process, the spring is not easy to fall off.

[0051] Please refer to the reference again. Figure 2 and Figure 3 Furthermore, the blade fork base 10 is provided with a fixing frame 13, and the guide rail 51 is housed within the space enclosed by the fixing frame 13. In this embodiment, the blade fork base 10 has a screw hole 15 on the bottom wall of the groove enclosed by the fixing frame 13, and the guide rail 51 has a connecting hole 513. The guide rail 51 is fixedly connected to the blade fork base 10 by screws 17 engaging with the connecting hole 513 and the screw hole 15. With the fixing frame 13, when the buckle 53 slides to the end of the slide groove 511, the fixing frame 13 limits the buckle 53 and houses the guide rail 51 within the fixing frame 13. The fixing frame 13 also limits and fixes the guide rail 51. During the installation of the fan blade 30, the guide rail 51 will not twist or wobble due to the presence of external force during the docking process, making the entire fixing structure more robust.

[0052] In this embodiment, the fixing frame 13 and the fork base 10 are integrally formed, and the overall structure is square. It can be understood that in other embodiments, the fixing frame 13 can be two opposing limiting plates. The openings at both ends of the guide rail 51's groove 511 are aligned with the two limiting plates. This arrangement can further save material and reduce costs for the fork base 10. Furthermore, in other structures, the guide rail 51 and the fork base 10 can also be integrally formed without the fixing frame 13. The opening of the guide rail 51's groove 511 can be limited by two limiting plates detachably connected to the fork base 10, preventing the buckle 53 from sliding out of the groove 511 during sliding.

[0053] The present invention also proposes a ceiling fan, which includes a ceiling fan blade mounting structure 100.
