Description

[Technical Field]

[0001] This utility model mainly relates to a quick-connect structure for ceiling fan blades. [Background Technology]

[0002] Nowadays, some people choose ceiling fan lights when purchasing lighting products because these lights can not only provide illumination but also be used as electric fans, making them very popular with consumers. When ceiling fan lights are not in use, people usually disassemble the fan blades for cleaning. To facilitate the disassembly of the fan blades, we propose a fan blade easy assembly and disassembly structure. [Utility Model Content]

[0003] To solve at least one of the above problems, this utility model proposes a new structural solution. The quick-connect structure for ceiling fan blades adopts the following technical solution:

[0004] A quick-connect structure for ceiling fan blades includes a fan head and blades;

[0005] The fan head is provided with a fixed cavity for connecting the fan blades. The fan blades are an integral structure, including a docking part and a wing part. The side of the docking part is bent outward to form an abutment part. One side of the fixed cavity is inclined to allow the abutment part to be engaged.

[0006] The fan head has a connection hole with a screw installed. The connection hole is connected to the fixing cavity. The screw passes through the connection hole to engage with the abutment part to prevent the fan blades from coming out of the fan head.

[0007] Preferably, the abutting portion protrudes from the side of the mating portion.

[0008] Preferably, the connection hole is inclined relative to the wall of the fixing cavity.

[0009] Preferably, the fan head includes a base cover, a chassis, a disc base, and a disc cover. The base cover extends out with a locking claw, which engages with the chassis and the disc base to assemble the base cover, chassis, and disc base into a whole.

[0010] Preferably, the chassis has a slot that extends through the chassis to allow the claws to engage; the base has a groove for the claws to engage.

[0011] Preferably, the fan head is provided with a channel that communicates with the fixed cavity; the end face of the mating part is provided with a protrusion that connects with the channel to restrict the fan blade from coming out of the fixed cavity.

[0012] Preferably, the disc cover is provided with a lock hole, the position of which corresponds to the position of the connecting hole.

[0013] The beneficial effects of this utility model compared with the prior art are:

[0014] This invention proposes a method where the mating part of the fan blade is inserted into the fixing cavity, and simultaneously, screws pass through the locking hole and the connecting hole, extending to engage with the abutting part inside the fixing cavity. At this point, the protrusion and the channel are also engaged together. Through these two fixing methods, the fan blade can be quickly assembled onto the fan head. It has the advantages of simple structure, compact fit, and reasonable design; therefore, it is a product with superior performance in both technical and economic aspects.

Detailed Implementation Methods

[0017] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] The preferred embodiment provided by this utility model is as follows: Figure 1 and Figure 2 As shown, a quick-connect structure for ceiling fan blades includes a fan head 1 and blades 2.

[0021] The fan head 1 is provided with a fixed cavity 11 for connecting the fan blades 2. The fan blades 2 are an integral structure, including a docking part 21 and a wing part 22. The side of the docking part 21 is bent outward to form an abutment part 23. One side of the fixed cavity 11 is inclined to allow the abutment part 23 to be inserted, so as to provide a connection space for the abutment part 23.

[0022] The fan head 1 has a connecting hole 12, and a screw 3 is installed in the connecting hole 12. The connecting hole 12 communicates with the fixing cavity 11. The screw 3 passes through the connecting hole 12 to engage with the abutment part 23 to prevent the fan blade 2 from detaching from the fan head 1. The connecting hole 12 has a corresponding thread for the screw 3 to be screwed in. The abutment part 23 protrudes from the side of the mating part 21 so that the screw 3 abuts against the abutment part 23. The connecting hole 12 is inclined relative to the wall of the fixing cavity 11 so that the force on the screw 3 is transmitted to the entire screw 3. Furthermore, the disc base 5 has a channel 13, which communicates with the fixing cavity 11. The end face of the mating part 21 has a protrusion 24, which engages with the channel 13 to prevent the fan blade 2 from detaching from the fixing cavity 11. The connection between the protrusion 24 and the channel 13, and the engagement between the screw 3 and the abutment part 23, work together to strengthen the connection of the fan blade 2.

[0023] The fan head 1 includes a base cover 4, a base plate 5, a disc base 6, and a disc cover 7. A connecting hole 12 and a fixing cavity 11 are provided on the disc base 6. A retaining claw 41 extends from the base cover 4, which passes through the base plate 5 and connects to the disc base 6 to assemble the base cover 4, base plate 5, and disc base 6 into a single unit. The base plate 5 has a slot 51 that penetrates through the base plate 5 for the retaining claw 41 to pass through; the disc base 6 has a groove 61 for the retaining claw 41 to engage.

[0024] The disc cover 7 is provided with a locking hole 71, the position of the locking hole 71 corresponds to the position of the connecting hole 12. Furthermore, the connecting hole 12 is arranged around the disc base 6, and the number of locking holes 71 corresponds to the number of connecting holes 12. The screw 3 passes through the locking hole 71 and connects to the connecting hole 12 to fix the disc cover 7 and the disc base 6 together.

[0025] Assembly process: The mating part 21 of the fan blade 2 is inserted into the fixing cavity 11, and the screw 3 passes through the locking hole 71 and the connecting hole 12 and extends to connect with the abutting part 23 in the fixing cavity 11. At this time, the protrusion 24 and the channel 13 are also engaged together. The fan blade 2 can be quickly assembled on the fan head 1 through the two fixing methods.
