Description

Technical Field

[0001] The utility model relates to a ceiling fan, in particular to a quick installation structure for the blades of a ceiling fan. Background Art

[0002] According to the existing technology, the assembly structure of the blades of a ceiling fan generally uses bolts to screw and fix the blades and the blade holder on the ceiling fan body. However, this structure combined by screwing with bolts is relatively cumbersome and time-consuming in the assembly process, and the more blades there are, the longer the time-consuming. Especially for a fan that needs to hang the motor on the ceiling first and then install the blades. In addition, the existing assembly structure of the blades of the ceiling fan has the following disadvantages:

[0003] 1. When the installer operates on a ladder alone, it is difficult to align the locking holes of the blade and the blade holder, and it is easy to damage the blade when screwing the screws.

[0004] 2. It is easy to bend the blade or the screw is not tightened, resulting in an unbalanced swing of the fan.

[0005] 3. The installer stands on the ladder for a long time to operate, and there is a risk of falling and getting injured.

[0006] In view of this, the inventor has finally developed this utility model based on his long-term research and development experience in the relevant technical field. Content of the Utility Model

[0042] Please refer to Figures 1 to 4 as shown, a preferred embodiment of a quick installation structure for a ceiling fan blade of the present utility model is disclosed, which includes a ceiling fan main body 10, a plurality of latching units 20 and a plurality of blades 30. In this embodiment, there are five latching units 20 and five blades 30. For the sake of simplicity, Figures 2 to 4 the assembly structure of one of the latching units 20 and the blade 30 is used as an illustration, and Figures 2 to 4 is Figure 1 vertically reversed, wherein:

[0043] For the ceiling fan main body 10, please refer to Figure 1 as shown. The ceiling fan main body 10 has an annular housing 11. There is a motor placement seat 12 in the annular housing 11. An annular groove 13 is formed between the motor placement seat 12 and the annular housing 11. In addition, a plurality of obliquely long openings 14 in the same direction are equidistantly provided on the annular housing 11.

[0044] For these latching units 20, please refer to Figures 2 to 4As shown, they are respectively equidistantly arranged in the annular groove 13. Each fastening unit 20 has a base 21 and a pressing plate 22. Among them, on both sides of the base 21, there are respectively a first footrest 211 and a second footrest 212 with different heights, so that the base 21 is fixed in the annular groove 13 of the ceiling fan main body 10 through the first footrest 211 and the second footrest 212. And the top surface of the base 21 forms an inclined setting corresponding to the long opening 14. The two sides of the pressing plate 22 are fixed on both sides of the base 21 and are parallel to the top surface of the base 21. And there is an accommodating groove 23 formed between the base 21 and the pressing plate 22. And the opening at the front end of the accommodating groove 23 faces the outer peripheral side of the ceiling fan main body 10 and exactly corresponds to the long opening 14 of the annular housing 11. In addition, there is a through hole 221 on the pressing plate 22, and an elastic buckle 222 is arranged in the through hole 221 of the pressing plate 22. One end of the elastic buckle 222 facing the outside is the fixed end, which is fixed on the pressing plate 22, and the end facing the inside is the free end, which obliquely extends into the accommodating groove 23. In addition, a stop piece 223 is arranged upward at the free end of the elastic buckle 222. And there are a plurality of elastic pressing pieces 224 on the pressing plate 22. One end of the elastic pressing piece 224 is the fixed end, which is fixed on the pressing plate 22, and the other end is the free end, which obliquely extends into the accommodating groove 23. Also, a upper guiding plate 213 is obliquely arranged upward at the front edge of the top surface of the base 21, and a lower guiding plate 225 is obliquely arranged downward at the front edge of the top surface of the pressing plate 22. The front edges of the upper guiding plate 213 and the lower guiding plate 225 both form an arc corresponding to the shape of the inner peripheral surface of the annular housing 11, so that the front edges of the upper guiding plate 213 and the lower guiding plate 225 can just abut against the inner peripheral surface of the annular housing 11.

[0045] For these blades 30, please refer to Figures 2 to 4 As shown, each end of the blade 30 has a root 31. The shape and size of the root 31 exactly correspond to the space of the accommodating groove 23. The width of the root 31 is smaller than the width of the blade 30, so that an arcuate shoulder 32 is formed between the blade 30 and the root 31. The shoulder 32 forms an arc corresponding to the shape of the outer peripheral surface of the annular housing 11, so that the shoulder 32 can just abut against the outer peripheral surface of the annular housing 11. In addition, a fixing hole 33 is arranged at the relative position of the root 31 of the blade 30 corresponding to the elastic buckle 222. So that the root 31 of the blade 30 is inserted into the accommodating groove 23 from the long opening 14 of the annular housing 11, and the elastic buckle 222 is buckled into the fixing hole 33 of the blade 30, and the blade 30 is fixed on the ceiling fan main body 10 under the abutting action of the stop piece 223.

[0046] For further understanding of the structural features, technical means and expected effects of the present invention, the assembly method of the present invention will be described below. I believe that a more in-depth and specific understanding of the present invention can be obtained therefrom, as described below:

[0047] When the blade 30 is to be installed on the ceiling fan main body 10, just insert the blade 30 into the long through-hole 14 of the annular housing 11. Due to the guiding action of the upper guiding plate 213 and the lower guiding plate 225, the root 31 of the blade 30 can be correctly guided and placed into the accommodating groove 23. When the shoulder 32 abuts against the outer peripheral surface of the annular housing 11, at this time, the elastic buckle piece 222 just snaps into the fixing hole 33 of the blade 30, and the abutting piece 223 abuts against the side wall of the fixing hole 33, so that the blade 30 is fixed on the ceiling fan main body 10. In this way, the assembly of the present invention is completed. And because these elastic pressing pieces 224 press the blade 30 tightly against the base 21, the blade 30 can be prevented from swinging up and down during rotation. In addition, by inserting the elastic buckle piece 222 of the fastening unit 20 into the corresponding fixing hole 33 of the blade 30, the blade 30 can be prevented from being thrown outwards due to the centrifugal force during rotation.

[0048] Conversely, when the blade 30 is to be disassembled from the ceiling fan main body 10, just pull the abutting piece 223 outwards to make the elastic buckle piece 222 disengage from the fixing hole 33. At this time, the blade 30 can be pulled outwards to disengage from the ceiling fan main body 10, and the disassembly of the blade 30 is completed.

[0049] From the above structural description, it can be seen that after the ceiling fan main body of the present invention is hung on the ceiling, the blade only needs to be correctly inserted to achieve the fixing effect. The operation is simple, and it is not necessary for the installer to stand on the ladder for a long time to lock the blade with screws, which greatly shortens the installation time of the blade and reduces the risk of the installer falling.

[0050] It is worth mentioning that the fastening unit of the present invention can also be installed on the ceiling fan main body without a housing or on the blade holder, and the same effect can be achieved.

[0051] However, the above is only a preferred and feasible embodiment of the present invention. Therefore, all equivalent structural changes made by applying the description and claims of the present invention should be included in the patent scope of the present invention.
