[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] In one embodiment, Figure 1-Figure 6 As shown, a variable speed ceiling fan blade includes a motor body 1, a motor support mechanism 2 is provided on the outside of the motor body 1, threaded columns 3 are fixedly installed in an equidistant ring on the top of the motor body 1, a mounting assembly is provided on the outside of the threaded columns 3, a sliding member 10 is sleeved on the top end of the motor body 1, a sliding sleeve 14 is slidably installed on the outside of the sliding member 10, a mounting member 18 is fixedly installed on the top of the sliding sleeve 14, and an adjustment assembly is provided on the outside of the mounting member 18.

[0030] In the present embodiment, by arranging a motor support mechanism 2 at the bottom of the motor body 1, the motor body 1 of the ceiling fan will not be driven by the fan blade body 6 to shake during operation, thereby increasing the stability of the ceiling fan. The fan blade body 6 and the motor body 1 can be conveniently fixed and installed through the installation component, and the interior of the fan blade body 6 is provided with a reinforcing rib 9, which can effectively support the fan blade body 6, thereby preventing the fan blade body 6 from deformation. Through the cooperation of the sliding sleeve 14 and the sliding member 10, the overall installation height of the ceiling fan can be changed, which is convenient for adjustment according to specific installation requirements, thereby improving the adaptability of the installation. Through the setting of the adjustment component, when the mounting seat 20 is not installed in a vertical state, the angle of the mounting member 18 can be adjusted so that the motor body 1 below is in a vertical state, thereby improving the stability of the ceiling fan.

[0031] In one embodiment, Figure 1 and Figure 3As shown, the installation component includes a connecting member 4, which is arranged on the outside of the threaded column 3, and the connecting member 4 is fixedly installed with the motor body 1 through the cooperation of the nut and the threaded column 3. A third installation hole 5 is equidistantly provided on the top of the connecting member 4, and a fan blade body 6 is sleeved on the outside of one end of the connecting member 4. A fourth installation hole 7 is provided on the top of the fan blade body 6, and a second bolt 8 is installed between the fan blade body 6 and the connecting member 4 through the fourth installation hole 7 and the third installation hole 5. A reinforcing rib 9 is fixedly installed inside the fan blade body 6. When the fan blade body 6 needs to be installed, the connecting member 4 is first fixedly installed with the motor body 1 through the cooperation of the nut and the threaded column 3, and then the fan blade body 6 is sleeved on the outside of the connecting member 4, and the fourth installation hole 7 is aligned with the third installation hole 5. The second bolt 8 is used to penetrate the fan blade body 6 and the connecting member 4 from the bottom of the fan blade body 6, and the fan blade body 6 and the connecting member 4 are fixedly installed by the second bolt 8, and the fan blade body 6 is provided with a reinforcing rib 9 inside the fan blade body 6, which can effectively support the fan blade body 6, thereby preventing the fan blade body 6 from deformation.

[0032] In one embodiment, Figure 2 As shown, the motor support mechanism 2 includes a motor support 201, and the motor support 201 is attached to the bottom of the motor body 1. The bottom of the motor support 201 is fixedly installed with fins 202. The bottom of the motor body 1 is equidistantly provided with first mounting holes 203 in a circular shape, and the bottom of the motor support 201 is equidistantly provided with second mounting holes 204 in a circular shape. A first bolt 205 is installed between the motor body 1 and the motor support 201 through the first mounting hole 203 and the second mounting hole 204. The motor body 1 will generate heat when working for a long time. The heat is conducted to the fins 202 through the motor support 201. The heat can be quickly dissipated through the fins 202, which has the function of heat dissipation and prolongs the service life of the motor body 1.

[0033] In one embodiment, Figure 5As shown, the adjustment component includes a mounting seat 20 and two fifth bolts 22, the mounting seat 20 is mounted on the outside of the mounting member 18, an eighth mounting hole 19 is opened on one side of the outside of the mounting member 18, and the number of the eighth mounting holes 19 is two, and ninth mounting holes 21 and arc grooves 23 are opened on both sides of the outside of the mounting seat 20, and the ninth mounting hole 21 is located above the arc groove 23, one of the eighth mounting holes 19 passes through the mounting seat 20 and the mounting member 18 respectively through the ninth mounting hole 21 and one of the eighth mounting holes 19, and another of the eighth mounting holes 19 passes through the mounting seat 20 and the mounting member 18 respectively through the arc groove 23 and another of the eighth mounting holes 19, The mounting base 20 is fixed to the ceiling by expansion bolts. First, the mounting base 20 is fixed to the ceiling by expansion bolts, and then the mounting piece 18 is moved to the inside of the mounting base 20. The eighth mounting hole 19 above is aligned with the ninth mounting hole 21. The mounting piece 18 and the mounting base 20 are fixed by the fifth bolt 22. Then, another fifth bolt 22 is used to pass through the arc groove 23 and the eighth mounting hole 19 below to penetrate the mounting base 20 and the mounting piece 18 respectively. If the mounting base 20 is not installed in a vertical state, the two fifth bolts 22 can be loosened so that the mounting piece 18 can be rotated and adjusted inside the mounting base 20. During adjustment, a level meter is used to measure to ensure that the motor body 1 is in a vertical state, thereby improving the stability of the ceiling fan.

[0034] In one embodiment, Figure 5 As shown, both sides of the outside of the sliding sleeve 14 are provided with sliding grooves 16, one side of the sliding member 10 is provided with a seventh mounting hole 15 penetrating therethrough, and the number of the seventh mounting holes 15 is two, and a fourth bolt 17 is installed between the sliding sleeve 14 and the sliding member 10 through the sliding groove 16 and the seventh mounting hole 15. When installing the ceiling fan, the environment of different installation points is different, sometimes it will interfere with the chandelier, and sometimes it will interfere with the beams. By loosening the two fourth bolts 17, the sliding member 10 can slide inside the sliding sleeve 14, thereby changing the overall height of the ceiling fan, which is convenient for adjustment according to the specific installation environment and improves the adaptability of the ceiling fan installation.

[0035] In one embodiment, Figure 6As shown, a fixing plate 24 is fixedly installed on the outside of the sliding sleeve 14, and an anti-falling component 26 is provided at the four corners of the top of the fixing plate 24, and the anti-falling component 26 includes a first mounting ring 261, and the first mounting ring 261 is installed at the four corners of the top of the fixing plate 24. The top of the fixing plate 24 is provided with a tenth mounting hole 25 adapted to the first mounting ring 261, and the first mounting ring 261 is fixedly installed with the fixing plate 24 through the cooperation of the tenth mounting hole 25 and the nut, and a first rope 262 is provided on the outside of the first mounting ring 261, and a first threaded member 263 is fixedly installed on one end of the first rope 262, and a threaded sleeve 264 is connected to the external thread of the first threaded member 263, and a second threaded member 265 is connected to the internal thread of one end of the threaded sleeve 264, and a second rope 266 is fixedly installed on one end of the second threaded member 265, and a second mounting ring 267 is provided at one end of the second rope 266, and the second mounting ring 267 is connected to the ceiling Fixed installation. The anti-fall component 26 is provided to provide the ceiling fan with an anti-fall function, which can effectively prevent the risk of the ceiling fan blades falling during operation and improve safety during use. The first mounting ring 261 is fixedly installed with the fixing plate 24 through the tenth mounting hole 25 and the nut, and the second mounting ring 267 is fixedly installed with the ceiling or the beam. After the first mounting ring 261 and the second mounting ring 267 are installed, it is necessary to ensure that the first rope 262 and the second rope 266 are straightened, otherwise the anti-fall effect is poor. It is difficult to ensure moderate tension during the installation of the existing anti-fall component 26, which affects the anti-fall effect. Since the threads of the second threaded member 265 and the first threaded member 263 are opposite to those of the first threaded member 263, when the first threaded member 263 and the second threaded member 265 are ensured to remain stationary and the threaded sleeve 264 is rotated, the first threaded member 263 and the second threaded member 265 move together to the inside or outside of the threaded sleeve 264, thereby adjusting the tension of the entire anti-fall component 26 to improve the anti-fall effect.

[0036] In one embodiment, Figure 1 As shown, a stabilizing component is provided on the outside of the fan blade body 6, and the stabilizing component includes a stabilizing member 27. The stabilizing member 27 is arranged on the top of the fan blade body 6. The top end of the second bolt 8 passes through the stabilizing member 27 and is connected with a nut. The stabilizing member 27 is ring-shaped. The setting of the stabilizing member 27 improves the overall stability of the multiple fan blade bodies 6, so that the fan blade bodies 6 are not easily deformed, and the ceiling fan works more smoothly.

[0037] In one embodiment, Figure 4As shown, sixth mounting holes 12 are provided on both sides of the outside of the sliding member 10, a fifth mounting hole 11 is provided on the outside of the top end of the motor body 1, and a third bolt 13 is installed between the sliding member 10 and the motor body 1 through the sixth mounting hole 12 and the fifth mounting hole 11. When the motor body 1 is installed, the top of the motor body 1 is inserted into the interior of the sliding member 10, and then the fifth mounting hole 11 is aligned with the sixth mounting hole 12, and finally the motor body 1 and the sliding member 10 are fixed with the third bolt 13.

[0038] The working principle of the present invention is: when installing the ceiling fan, first fix the connecting member 4 to the motor body 1 through the cooperation of the nut and the threaded column 3, then put the fan blade body 6 on the outside of the connecting member 4, align the fourth mounting hole 7 with the third mounting hole 5, use the second bolt 8 to penetrate the fan blade body 6 and the connecting member 4 from the bottom of the fan blade body 6, fix the fan blade body 6 and the connecting member 4 with the second bolt 8, and then install the stabilizing member 27 on the top of multiple fan blade bodies 6.

[0039] Insert the top of the motor body 1 into the interior of the sliding member 10, and then align the fifth mounting hole 11 with the sixth mounting hole 12, and finally use the third bolt 13 to fix the motor body 1 and the sliding member 10, and fix the mounting seat 20 to the ceiling through the expansion bolts, and then move the mounting member 18 to the interior of the mounting seat 20, align the eighth mounting hole 19 above with the ninth mounting hole 21, and fix the mounting member 18 to the mounting seat 20 through the fifth bolt 22, and then use another fifth bolt 22 to pass through the arc groove 23 and the eighth mounting hole 19 below to penetrate the mounting seat 20 and the mounting member 18 respectively. If the mounting seat 20 is not installed in a vertical state, loosen the two fifth bolts 22 so that the mounting member 18 can be rotated and adjusted inside the mounting seat 20. During adjustment, measure with a level to ensure that the motor body 1 is in a vertical state, thereby improving the stability of the ceiling fan.

[0040] The first mounting ring 261 is fixedly installed on the fixing plate 24 through the tenth mounting hole 25 and the nut, and the second mounting ring 267 is fixedly installed on the ceiling or the beam. After the first mounting ring 261 and the second mounting ring 267 are installed, it is necessary to ensure that the first rope 262 and the second rope 266 are straightened. Since the threads of the second threaded member 265 and the first threaded member 263 are opposite, when the first threaded member 263 and the second threaded member 265 are rotated without moving the threaded sleeve 264, the first threaded member 263 and the second threaded member 265 move together to the inside or outside of the threaded sleeve 264, thereby adjusting the tension of the entire anti-fall assembly 26 to improve the anti-fall effect.

[0041] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
