Description

Technical Field

[0001] This utility model relates to the field of fan equipment, and in particular to a fan blade mounting structure and a ceiling fan light using the structure. Background Technology

[0002] With the improvement of people's living standards, ceiling fan lights, as a type of home appliance that combines lighting and ventilation functions, have been widely used in homes and commercial spaces. Existing small pendant lights are typically used in small spaces such as outdoor tents and mosquito nets. By installing fan blades, the pendant light also functions as a fan, forming a ceiling fan light. Ceiling fan lights usually consist of a lamp body, motor, and fan blades, among which the installation structure of the fan blades directly affects the ease of use and safety of the product.

[0003] Currently, ceiling fan lights on the market typically package the fan blades and the light body separately for ease of packaging and transportation, requiring users to install them themselves. Traditional fan blade installation methods often use screws for fixing, which is not only cumbersome to install but also prone to the safety hazard of loose screws causing the fan blades to fall off.

[0004] Several improved fan blade mounting structures exist in the prior art. For example, Chinese patent document CN217682451U discloses a fan blade disassembly structure and ceiling fan light, in which a mounting protrusion on the base engages with a mounting recess at the tail end of the fan blade, and a pressure cap is threadedly connected to the base. The pressure cap's embossed design enables quick assembly and disassembly of the fan blade. While this structure facilitates disassembly, it requires first attaching the fan blade to the base and then installing the pressure cap to lock the blade in place. Furthermore, Chinese patent document CN222596384U proposes a fan blade mounting structure including a fixing base, blades, a first snap-fit ​​assembly, a second snap-fit ​​assembly, and other components. Although this structure provides a strong connection, the numerous components and complex structure hinder mass production and cost reduction.

[0005] In summary, existing fan blade mounting structures have the following problems: firstly, their complex structure and numerous components increase manufacturing costs; secondly, installation is cumbersome, resulting in a poor user experience. Therefore, there is an urgent need for a simple, easy-to-install, and securely connected fan blade mounting structure to improve the user experience and safety of ceiling fan lights. Utility Model Content

[0006] The main purpose of this utility model is to provide a fan blade installation structure and a ceiling fan light, which aims to make fan blade installation convenient and stable.

[0007] This utility model proposes a fan blade mounting structure for mounting fan blades to a rotating part. It includes a insertion slot on the rotating part and a connector adapted to the insertion slot at the end of the fan blade. The insertion slot opens laterally outward on the circumferential surface of the rotating part. A snap-fit ​​groove is provided on either the inner wall of the insertion slot or the connector, while the other provides a perforated groove opposite to the snap-fit ​​groove. A cantilever is laterally positioned within the perforated groove, capable of being elastically pressed in a direction perpendicular to the perforated groove. The end of the cantilever... The device includes a snap-fit ​​connector that protrudes into and fits the snap-fit ​​groove. The snap-fit ​​connector's surface facing the insertion direction of the connector is an inclined sliding surface. When the connector is inserted into the groove, the snap-fit ​​connector abuts against the outer end of the groove's surface via the inclined sliding surface. As the connector is inserted, the outer end of the groove's surface presses against the inclined sliding surface, forcing the snap-fit ​​connector and the cantilever end to rise or fall until the bottom of the snap-fit ​​connector moves into the groove's surface, until the snap-fit ​​connector is fully inserted into the groove. By inserting the connector into the groove, the snap-fit ​​connector snaps into the groove, achieving a secure mounting of the fan blade onto the rotating part. The installation operation is simple.

[0008] Preferably, the insertion slot is disposed on the front peripheral side of the rotating part, and the surface of the insertion slot facing the front end of the rotating part has an opening.

[0009] Preferably, the snap-fit ​​groove is disposed on the inner wall surface of the insertion groove opposite to the opening, the hollowed-out groove and the cantilever are disposed on the insertion connector, and there is a gap between the two sides of the cantilever and the inner wall of the hollowed-out groove. A toggle head is protruding from the side of the cantilever facing away from the snap-fit ​​connector, and the cantilever and the toggle head protrude from the opening. The user can lift the cantilever and snap-fit ​​connector by pushing up the toggle head, causing the snap-fit ​​connector to disengage from the snap-fit ​​groove, thereby allowing the insertion connector to be pulled out of the insertion groove, achieving the purpose of disassembling the fan blade.

[0010] Preferably, the rotating part is a cylindrical structure, and the end of the fan blade is provided with an arc-shaped wall surface that can fit against the peripheral side surface of the rotating part, and the connector is located at the end of the arc-shaped wall surface.

A cantilever is provided laterally in the perforated groove, which can be elastically pressed in a direction perpendicular to the perforated groove. The cantilever has a protrusion towards the snap-fit ​​groove and... The snap-fit ​​connector is adapted to the snap-fit ​​groove. The surface of the snap-fit ​​connector facing the insertion direction of the plug is an inclined sliding surface. When the plug is inserted into the plug groove, the snap-fit ​​connector abuts against the outer end of the snap-fit ​​groove surface through the inclined sliding surface. As the plug is inserted, the outer end of the snap-fit ​​groove surface presses against the inclined sliding surface, forcing the snap-fit ​​connector and the cantilever end to rise or fall until the bottom of the snap-fit ​​connector moves on the snap-fit ​​groove surface until the snap-fit ​​connector moves into the snap-fit ​​groove.

[0033] Example 1:

[0034] Reference Figures 1 to 6 This utility model provides a fan blade mounting structure for mounting fan blade 2 onto a rotating part 1. The mounting structure mainly includes a plug groove 10 provided on the rotating part 1 and a plug connector 20 provided at the end of the fan blade 2, which are mutually compatible.

[0035] The insertion slot 10 has a laterally outward opening on the peripheral side of the rotating part 1. For example... Figure 4 As shown, the insertion groove 10 is provided on the front peripheral side of the rotating part 1, and the surface of the insertion groove 10 facing the front end of the rotating part 1 has an opening. A snap-fit ​​groove 13 is provided on the inner wall surface of the insertion groove 10 opposite to the opening, that is, the snap-fit ​​groove 13 is provided on the bottom surface inside the insertion groove 10, and the plug connector 20 has a hollow groove opposite to the surface where the snap-fit ​​groove 13 is located.

[0036] A cantilever 21 is provided horizontally in the hollowed-out groove, such as Figure 2As shown, there is a gap between the two sides of the cantilever 21 and the inner wall of the hollow groove, so that the cantilever 21 can be elastically pressed (lifted or pressed down) in the direction perpendicular to the hollow groove, and reset by the elastic force of the cantilever after the external force is removed. The end of the cantilever 21 is provided with a snap-fit ​​connector 22 that protrudes toward the snap-fit ​​groove 12 and is adapted to the snap-fit ​​groove 12. The surface of the snap-fit ​​connector 22 facing the insertion direction of the plug connector 20 is an inclined sliding surface, which can contact the outer end of the surface where the snap-fit ​​groove 13 is located (i.e., the bottom surface inside the plug groove 10).

[0037] A toggle head 23 is raised on the back side of the cantilever 21 facing the snap-fit ​​connector 22. The snap-fit ​​connector 22 and the toggle head 23 are respectively located on the front and back sides of the end of the cantilever 21. The cantilever 21 and the toggle head 23 are exposed from the opening for easy operation.

[0038] During the insertion of the connector 20 into the connector slot 10, the snap connector 22 abuts against the outer end of the inner bottom surface of the connector slot 10 through the inclined sliding surface. As the connector 20 is inserted, the outer end of the inner bottom surface of the connector slot 10 presses against the inclined sliding surface, forcing the snap connector 22 and the cantilever end to rise to the bottom of the snap connector and move on the inner bottom surface of the connector slot 10 until the snap connector 22 moves into the snap slot 12, thereby achieving snap-fit ​​fixation.

[0039] like Figure 3 and Figure 4 As shown, the rotating part 1 has a cylindrical structure, and the end of the fan blade 2 is provided with a vertically arranged arc-shaped wall surface 26 that can fit against the peripheral side surface of the rotating part 1. The connector 20 is located at the end of the arc-shaped wall surface 26. This design allows the fan blade 2 and the rotating part 1 to fit tightly together, improving the connection stability.

[0040] The insertion slot 10 includes a first insertion interface 11, which is arranged along the insertion direction and spaced apart from each other, for connecting the two sides of the insertion connector 20, and a second insertion interface 12, which is located at the inner end in the insertion direction for connecting the front end of the insertion connector 20. The inner end wall of the insertion slot 10 is arc-shaped, and the part of it opposite to the first insertion interface 11 is arc-shaped, referred to as the first wall.

[0041] The front end of the connector 20 is arc-shaped to fit the inner end face of the connector slot 10, including a central connector 24 and extensions 25 on both sides. The central connector 24 is inserted into the second connector 12, and the extensions 25 extend into the inner end of the first connector 11. The end of the extensions 25 faces the first wall surface 13 and fits against the first wall surface 13, ensuring that the connector 20 is accurately positioned and tightly fitted in the connector slot 10, thereby improving connection stability.

[0042] like Figure 5 and Figure 6As shown, this fan blade mounting structure is applied to a ceiling fan light. The entire ceiling fan light also includes a connecting plate 3, a rear shell 4, a light source, and a lampshade 5. Through this plug-in connection structure, the fan blade 2 can be easily installed onto the rotating part 1, and the connection is stable and reliable. At the same time, when disassembly is required, simply press the toggle head 23 to disengage the snap-fit ​​connector 22 from the snap-fit ​​slot 13, and the fan blade 2 can be easily removed from the rotating part 1, greatly simplifying the installation and disassembly process.

[0043] Example 2:

[0044] Reference Figures 5 to 6 The ceiling fan light provided in this embodiment includes a connecting plate 3, a motor and a light source mounted on the connecting plate 3, a rotating part 1 connected to the rotating shaft of the motor, and a rear shell 4 covering the back of the connecting plate 3. The rotating part 1 protrudes from the front end of the connecting plate 3, the light source surrounds the periphery of the rotating part 1, and fan blades 2 are mounted on the rotating part 1.

[0045] The fan blade 2 is mounted onto the rotating part 1 using the fan blade mounting structure described in Embodiment 1. As described in Embodiment 1, the fan blade mounting structure includes a insertion groove 10 disposed on the rotating part 1 and a insertion connector 20 disposed at the end of the fan blade 2. The insertion groove 10 is laterally open outward on the peripheral side surface of the rotating part 1, and the insertion connector 20 is adapted to the insertion groove 10.

[0046] In this embodiment, a ring-shaped lampshade 5 is connected to the front end of the connecting plate 3. The lampshade 5 surrounds the outer periphery of the rotating part 1, enclosing the light source inside. This design protects the light source from the lampshade 5, while the lampshade 5 can diffuse or scatter the light, making the lighting effect softer and more uniform.

[0047] like Figure 5 As shown, the annular structure of the lampshade 5 and the rotating part 1 form a concentric circle layout, ensuring that the light source can emit light evenly in all directions. The lampshade 5 can be made of a semi-transparent material, which can both transmit light and serve a certain decorative effect.

[0048] A control circuit can be installed on the back of the connecting plate 3. The control circuit is electrically connected to the light source and the motor.

[0049] When the ceiling fan light is working, the motor drives the rotating part 1 to rotate, which in turn drives the fan blades 2 mounted on the rotating part 1 to rotate and generate airflow; at the same time, the light source is powered on and emits light, which is scattered outward through the lampshade 5 to achieve the lighting function. This structural design organically combines the fan and lighting functions, saving space and increasing the convenience of use.

[0050] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on these embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Although this utility model has been described in detail with reference to the above embodiments, those skilled in the art can still combine, add, delete, or otherwise adjust the features of the various embodiments of this utility model according to the circumstances without conflict or creative effort, thereby obtaining different technical solutions that do not fundamentally depart from the concept of this utility model. These technical solutions are also within the scope of protection of this utility model.
