Description

Technical Field

[0001] This utility model relates to the field of industrial large fan technology, specifically to the anti-shaft breakage structure of industrial large fan bushings. Background Technology

[0002] With societal development, large ceiling fans are widely used in homes, offices, shopping malls, and other places. However, due to various reasons, during the use of existing large ceiling fans, the main shaft may break due to insufficient strength or aging, causing the ceiling fan to fall and posing a safety hazard.

[0003] To address the aforementioned issues, we propose a shaft breakage prevention structure for industrial large fans. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a shaft breakage prevention structure for industrial ceiling fans, which can effectively prevent the main shaft of the motor of the ceiling fan from breaking and improve the safety of the use of the ceiling fan.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] The anti-breakage shaft structure of the industrial fan includes a main shaft and a suspension rod. The bottom of the suspension rod is connected to the main shaft, and the suspension rod and the main shaft are connected by an anti-breakage shaft sleeve.

[0007] As an improvement, the anti-breakage shaft component of the bushing includes a bushing and an arc-shaped mounting plate; the bushing is in the form of an I-shaped cylindrical structure, and after being rotated and sleeved on the main shaft, a pair of arc-shaped mounting plates are fixed on the top surface. After the two arc-shaped mounting plates are inserted into the rod, they are fixed in the rod by bolts.

[0008] As an improvement, the bushing anti-breakage component also includes a movable disc, which is a flange structure and is passed through the middle cylinder of the bushing.

[0009] As an improvement, the upper side plate of the bushing is a square plate structure, and bushing through holes are reserved at the four corners.

[0010] The advantages of this utility model compared with the prior art are as follows:

[0011] 1. Simple structure and highly practical;

[0012] 2. It can effectively prevent the main shaft of the large ceiling fan motor from breaking, thus improving the safety of use;

[0013] 3. Easy to install and suitable for various types of large ceiling fans;

[0014] 4. The four bushing through holes allow steel wire ropes to be pulled to the ceiling, effectively preventing the fan from shaking or vibrating.

[0015] 5. The movable disc can fall downwards along with the main unit after the main shaft of the large ceiling fan motor breaks, but the fixed disc welded to the lower end of the bushing cannot prevent the motor as a whole from falling. Attached Figure Description

[0021] In the description of this utility model, it should be understood that the terms "center," "lateral," "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] The anti-breakage shaft structure of the industrial large fan includes a main shaft 1 and a suspension rod 2. The bottom of the suspension rod 2 is connected to the main shaft 1 via an anti-breakage shaft sleeve 3. Specifically:

[0024] The anti-breakage shaft component 3 includes a shaft sleeve 31, an arc-shaped mounting plate 32, and a movable disc 33. The shaft sleeve 31 has an overall I-shaped cylindrical structure and is rotatably fitted onto the main shaft 1. A pair of arc-shaped mounting plates 32 are fixed on its top surface. The two arc-shaped mounting plates 32 are inserted into the hanger rod 2 and then fixed inside the hanger rod 2 by bolts. The movable disc 33 has a flange structure and is passed through the middle cylinder of the shaft sleeve 31. The upper side plate of the shaft sleeve 31 has a square plate structure, and shaft sleeve through holes 34 are reserved at the four corners.

[0025] It is worth mentioning that the four corner bushing through holes 34 can be used to fix the steel wire rope, preventing the fan from shaking or vibrating. The lower end of the bushing anti-breakage component 3 is fixedly welded with a metal disc.

[0026] The central hole diameter of the movable disc 33 is slightly larger than that of the central cylinder of the anti-breakage shaft component 3, and the movable disc 33 can rotate synchronously when the fan host is running.

[0027] In the specific implementation of this embodiment:

[0028] During installation, the bushing 31 is fitted onto the main shaft 1 and secured with a nut at the tail end of the main shaft 1 to prevent the bushing 31 from coming off. The movable disc 33 is fixed to the fan blade bolts at the upper end of the main unit of the ceiling fan, so that the movable disc 33 can rotate synchronously when the main unit of the fan is rotating, without interfering with the stationary state of the suspension rod 2.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
