Description

Technical Field

[0001] This utility model relates to the field of ceiling fan equipment technology, specifically to a ceiling fan with an anti-fall-off function. Background Technology

[0002] Ceiling fans are a common type of ventilation equipment, widely used in homes, offices, factories, and other places. However, safety issues during the use of ceiling fans, especially the problem of the fan body falling off, have always been a focus of attention in the industry.

[0003] Existing ceiling fan suspension systems typically use simple structures such as hooks or brackets for fixation. While these structures can meet usage requirements in most cases, the risk of the fan body falling off remains under extreme conditions, such as strong winds, earthquakes, or component aging due to long-term use. Furthermore, some ceiling fans are not adequately designed and manufactured with considerations for the balance of the fan blades and shaft, the driving force of the motor, and safety measures in mind, which may also lead to the risk of the fan swaying or falling off during operation.

[0004] To address these issues, some improvements have been proposed in existing technologies. For example, some ceiling fans incorporate reinforced mounting brackets or use higher-strength materials to enhance the stability of the suspension system. However, these solutions often only alleviate the problem to a certain extent and cannot fundamentally eliminate the risk of the ceiling fan falling off. Furthermore, while some designs improve safety, they increase installation complexity or cost, hindering widespread adoption.

[0005] Therefore, there is an urgent need for a ceiling fan with anti-fall-off function, which can effectively prevent the ceiling fan body from falling off during use while ensuring easy installation and cost-effectiveness, thereby providing users with higher safety. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a ceiling fan with a simple structure and good anti-fall-off effect.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a ceiling fan with anti-fall function, comprising a hanging rod and a ceiling fan body, wherein an extension rod is provided on the upper part of the ceiling fan body, and an anti-fall connector is provided between the extension rod and the hanging rod, the anti-fall connector comprising a base plate, wherein two ends of the base plate are provided with snap-fit ​​plates that are respectively connected to the hanging rod and the extension rod.

[0008] As a further improvement to the above technical solution:

[0009] The lower part of the anti-fall connector is provided with a limiting plate sleeved on the outside of the extension rod, and the upper part of the limiting plate is provided with a clamping plate connected to the ceiling fan body.

[0010] The clamping plate includes a ring plate connected to the ceiling fan body, and the inner side of the ring plate is provided with a snap-fit ​​extension edge located on the limiting plate.

[0011] The number of the fall arrestor connectors is two, and they are symmetrically distributed about the center line of the extension rod.

[0012] The extension rod has mounting platforms on its side walls for placing snap-fit ​​plates.

[0013] The ceiling fan body includes a motor and multiple fan blades. A positioning plate for mounting the fan blades is provided above the motor, and a plug-in plate for connecting to the fan blades is provided at the edge of the positioning plate.

[0014] The number of plug-in plates is multiple and they are evenly distributed along the circumference of the positioning plate. After the multiple plug-in plates are connected to the fan blades, an annular pad is set above the fan blades.

[0015] The beneficial effects of this utility model embodiment are as follows: The ceiling fan with anti-fall function includes a hanging rod and a ceiling fan body. An extension rod is provided on the upper part of the ceiling fan body. The extension rod and the hanging rod are connected and fixed by an anti-fall connector. The anti-fall connector includes a base plate located between the hanging rod and the ceiling fan body. The two ends of the base plate are provided with snap-fit ​​plates that are respectively connected to the hanging rod and the extension rod. The snap-fit ​​plates are detachably connected to the hanging rod and the extension rod by bolts. The anti-fall connector can improve the connection strength between the ceiling fan body and the hanging rod. The structure is simple and convenient for installation and subsequent maintenance.

[0016] The lower part of the anti-fall connector is equipped with a limiting plate that is sleeved on the outside of the extension rod. Above the limiting plate is a clamping plate that is connected to the ceiling fan body. If the ceiling fan body falls off, the clamping plate and the limiting plate can be used to prevent the ceiling fan body from falling. Attached Figure Description

[0023] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0024] like Figure 1-5 As shown, the ceiling fan with anti-fall function in this embodiment includes a hanging rod 1 and a ceiling fan body 2. An extension rod 3 is provided on the upper part of the ceiling fan body 2. The extension rod 3 is connected and fixed to the hanging rod 1 by an anti-fall connector. The anti-fall connector includes a base plate 4 located between the hanging rod 1 and the ceiling fan body 2. The two ends of the base plate 4 are provided with snap-fit ​​plates 5 that are respectively connected to the hanging rod 1 and the extension rod 3. The snap-fit ​​plates 5 are detachably connected to the hanging rod 1 and the extension rod 3 by bolts. The anti-fall connector can improve the connection strength between the ceiling fan body 2 and the hanging rod, and the structure is simple, convenient for installation and subsequent maintenance.

[0025] The lower part of the anti-fall connector is provided with a limiting plate 6 sleeved on the outside of the extension rod 3. Above the limiting plate 6 is a clamping plate 7 connected to the ceiling fan body 2. If the ceiling fan body 2 falls off, the clamping plate 7 and the limiting plate 6 can be used to prevent the ceiling fan body 2 from falling.

[0026] The clamping plate 7 includes a ring plate 8 that is detachably connected to the ceiling fan body 2 by bolts. The inner side wall of the ring plate 8 is provided with a snap-fit ​​extension 9 that extends to the limiting plate 6. The snap-fit ​​extension 9 can increase the overlapping area between the clamping plate 7 and the limiting plate 6, thereby improving the anti-fall-off performance of the ceiling fan body 2.

[0027] There are two fall arrestor connectors, which are symmetrically distributed about the center line of extension rod 3. The two fall arrestor connectors are detachably connected to extension rod 3 by bolts.

[0028] The side walls on both sides of the extension rod 3 are provided with mounting platforms 10 for placing the snap-fit ​​plate 5. The design of the mounting platforms 10 facilitates the placement of the snap-fit ​​plate 5 and improves installation efficiency.

[0029] The ceiling fan body 2 includes a motor 11 and multiple fan blades 12. A positioning plate 13 for mounting the fan blades 12 is provided above the motor 11. A plug plate 14 for connecting to the fan blades 12 is provided at the edge of the positioning plate 13. The plug plate 14 is connected to the fan blades 12 by bolts.

[0030] There are multiple plug-in plates 14, which are evenly distributed along the circumference of the positioning plate 13. After the multiple plug-in plates 14 are connected to the fan blades 12 respectively, an annular pad 15 is provided above the fan blades 12. The annular pad 15, the plug-in plates and the fan blades 12 are connected and fixed by bolts. The function of the annular pad 12 is to strengthen the connection between the multiple fan blades 12, and at the same time to protect the fan blades 12 from being crushed on the surface of the fan blades 12 when the bolts are tightened.
