The utility model relates to a ceiling fan blade frame, in particular to an integrated ceiling fan blade assembly.

As shown in Figure 1, the first type of ceiling fan 10 in the past is provided with a hanging ball 111 on the top of the suspension rod 11, which is suspended from the ceiling with a tray 112, and the bottom end of the suspension rod 11 is fixed on a ceiling fan body 12. At the top, the ceiling fan body 12 is provided with a motor 13, and the rotor 131 of the motor 13 is locked with a plurality of blade holders 14 (about four to five), and a switch box 15 is connected to the bottom of the ceiling fan body 12 for Control the operation of the ceiling fan 10. When the ceiling fan 10 is packed, the hanging ball 111, the tray 112, the boom 11, the ceiling fan body 12 and the switch box 15 have been assembled into one body, and the leaf frame 14 and the blade 16 parts If it is not assembled on the ceiling fan body 12, it will be put into the box first, and when the consumer buys it back, the leaf frame 14 will be locked on the rotor 131 of the motor 13 with bolts, and the blade 16 will be locked on the leaf frame 14, and hang the ceiling fan 10 on the ceiling, but the first ceiling fan 10 in the past, after being assembled, can disturb the indoor air flow and provide a comfortable and cool indoor space, but it still has the following disadvantages:

1. Because the leaf frame 14 is not assembled before leaving the factory, it is easy to cause unstable and inaccurate locks if it is assembled by non-professional consumers. Therefore, the quality of self-assembly is poor.

Two, because the leaf frame 14 is formed by casting, in order to save material, the stem portion 141 of the leaf frame 14 is made into a U-shaped structure to reinforce its strength, but the leaf frame 14 must be electroplated on the surface treatment to obtain a beautiful appearance on the surface, and before the electroplating treatment, acidic substances must be used for cleaning. If the acidic substance is used for cleaning for too long, the strength of the leaf frame 14 will be relatively reduced, making the leaf frame 14 is relatively poor in quality, and when making the ceiling fan 10, if defective or flawed blade holders 14 are mixed into it, when the blade holders 14 are locked to the rotor 131 and rotate normally, under the action of centrifugal force, the blade holders 14 will be damaged. Frame 14 breaks and flies out the danger of falling and injuring people.

In order to solve the above-mentioned shortcoming of the first ceiling fan in the past, as shown in Figures 2 and 3, it is a ceiling fan blade safety cable device of Taiwan New Patent No. 91261. This ceiling fan 20 is composed of a suspension rod 21, a ceiling fan body 22, a plurality A blade frame 23, a plurality of blades 24 and a plurality of safety auxiliary components 25, the safety auxiliary components 25 are steel wires with rings 251, 252 fixed at both ends.

The ceiling fan body 22 is provided with a motor 26 inside, and the blade frame 23 is screwed on the rotor 261 of the motor 26 by using a plurality of bolts 231 together with a collar 251 at one end of the safety auxiliary member 25, and the blade 24 is also screwed on the rotor 261 of the motor 26 by using a plurality of bolts 241 together with The other end collar 252 of the safety auxiliary component 25 is locked on the screw hole 232 of the leaf portion 234 of the blade frame 23 .

The ceiling fan 20 is installed with the safety auxiliary component 25. If the blade holder 23 with poor casting quality or defects is used on the ceiling fan 20, the stem 233 of the blade holder 23 will be rotated when the ceiling fan 20 rotates normally. When the centrifugal force breaks, the safety auxiliary component 25 can prevent the blade 24 from flying out and falling and hurting people. Therefore, the user has enough time to find that the blade holder 23 is broken, and can turn off the power as soon as possible. .

Although this ceiling fan 20 can solve the problem of the first type of blade frame 14 breaking, flying, falling and injuring people in the past, when the ceiling fan 20 is packaged at the factory, the blade frame 23 must wait until the consumer buys it back before it can be used by itself. Locking, and the shortcomings of the blade frame 23 made of casting, plus the blade frame 23 is locked by the consumer, the quality of assembly is poor, and it is relatively unsafe. In addition, because the blade 24 It is usually made of wood or plastic material. When the blade 24 is locked to the blade frame 23 after normal use and operation for a period of time, the screw 231 will gradually loosen due to the thermal expansion and contraction of the wood, and the Therefore, the screw 231 must be re-tightened, which is time-consuming and laborious, and if the user does not notice that the screw 231 is loosened, it will cause danger during use.
