Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a fan with a fall-prevention steel wire rope. Background Technology

[0002] Currently, traditional fans generally adopt a single-point suspension structure design, with the core load-bearing system consisting of a motor, suspension rod, and fan blade assembly. However, this structural design has safety hazards in practical applications: First, the rigid connection between the motor and suspension rod via flange bolts can lead to stress concentration at the connection point under long-term alternating loads (especially the radial torque generated by the dynamic imbalance of the fan blades), resulting in a decrease in strength. Second, existing connectors do not consider long-term use factors such as material fatigue and environmental corrosion. When the connectors undergo fatigue deformation, users are unaware of the risks, posing a safety hazard of the motor falling and injuring people. Utility Model Content

[0003] In response to the problem of fatigue fracture at the connection between the motor and the suspension rod in existing fans, which can easily lead to falling and injury, this utility model provides a fan with a fall-prevention steel wire rope.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A fan with a fall-prevention steel wire rope includes a fan motor, a boom, and a fall-prevention steel wire rope. The fan motor has a mounting hole at its bottom and a connecting rod fixed to its top. The end of the connecting rod is fixedly connected to the boom. The boom has a first receiving channel, and the connecting rod has a second receiving channel. The fall-prevention steel wire rope is disposed within the first and second receiving channels. A steel sleeve is fixed to the end of the fall-prevention steel wire rope, and a safety rope flange is engaged with the steel sleeve, which in turn engages with the mounting hole.

[0006] Furthermore, the mounting hole is divided into a large hole section and a small hole section, wherein the diameter of the large hole section is larger than the diameter of the small hole section.

[0007] Furthermore, the safety rope flange has a through hole running vertically through the top and bottom, the through hole being adapted to the fall arrest wire rope, and the safety rope flange is divided into a connecting part located at the top and a snap-fit ​​part located at the bottom.

[0008] Furthermore, the diameter of the connecting portion is smaller than the diameter of the snap-fit ​​portion.

[0009] Furthermore, the connecting portion is disposed within the small hole section, and the snap-fit ​​portion is disposed within the large hole section.

[0010] Furthermore, the large hole section is equipped with an end cap, which is fixedly connected to the snap-fit ​​portion.

[0011] Furthermore, a snap-fit ​​groove adapted to the steel sleeve is provided on one side of the bottom of the snap-fit ​​part. The snap-fit ​​groove communicates with the through hole and forms a connection channel adapted to the steel wire rope.

[0012] Furthermore, the fall arresting wire rope includes a first connecting section and a second connecting section, wherein the first connecting section is disposed in a first receiving channel and the second connecting section is disposed in a second receiving channel.

[0013] Furthermore, a male connector is fixed to the lower end of the first connecting segment, and a female connector is fixed to the upper end of the second connecting segment. The male connector and the female connector are threaded together, and the steel sleeve is fixed to the lower end of the second connecting segment.

[0014] Furthermore, the upper opening of the first receiving channel is located on one side of the upper part of the boom, and the lower opening is located on one side of the lower part of the boom.

[0015] The beneficial effects of this utility model are as follows: By setting an anti-fall steel wire rope in the fan, a safety protection structure is formed, which avoids the problem of the fan motor falling and injuring people, thus improving the safety of use. In addition, the anti-fall steel wire rope is connected by steel sleeve and snap-fit ​​groove, and male and female threads, which effectively simplifies the installation steps, reduces the installation difficulty for workers, and effectively improves the installation efficiency.

[0024] This utility model discloses a fan with a fall-prevention steel wire rope. The following describes one embodiment of this utility model with reference to the accompanying drawings.

[0025] Combination Figure 1 and Figure 2 As shown, a fan with a fall-prevention steel wire rope includes a fan motor 1, a suspension rod 3, and a fall-prevention steel wire rope 4. The fan motor 1 is an external rotor type motor. A mounting hole is provided at the bottom axis of the fan motor 1. The mounting hole is divided into a large hole section and a small hole section. The large hole section is located below the small hole section, and its diameter is larger than that of the small hole section. A stepped flared structure is formed between the large hole section and the small hole section. A connecting rod 2 is fixedly connected to the top axis of the fan motor 1. The upper end of the connecting rod 2 is fixedly connected to the lower end of the suspension rod 3 by several bolts. The suspension rod 3 has a first receiving channel with openings at both ends, namely an upper opening and a lower opening. The upper opening is located on one side of the upper part of the suspension rod 3, and the lower opening is located on one side of the lower part of the suspension rod 3. The connecting rod 2 has a second receiving channel with openings at both ends, namely a first opening and a second opening. The first opening is located on one side of the upper part of the connecting rod 2, and the second opening is located at the center of the bottom of the connecting rod 2. An end cap 9 is provided at the opening at the bottom of the large hole section, and an accommodating space is formed between the end cap 9 and the large hole section.

[0026] Combination Figure 3 and Figure 4 As shown, the safety rope flange 7 is disposed within the receiving space, and the end cap 9 is fixedly connected to the safety rope flange 7 by several bolts. The mounting flange has a through hole 701 extending vertically, and is fixedly connected to the bottom of the connecting rod 2 by several bolts. The through hole 701 communicates with the second receiving channel. The safety rope flange 7 is divided into a connecting part 702 located at the upper part and a snap-fit ​​part 703 located at the lower part. The diameter of the connecting part 702 is smaller than the diameter of the snap-fit ​​part 703. The connecting part 702 is disposed within the small hole, and the snap-fit ​​part 703 is disposed within the large hole section, so that the safety rope flange 7 as a whole achieves a snap-fit ​​fit with the flared structure located at the bottom of the mounting hole. A snap-fit ​​groove 704 is provided inwardly on one side of the bottom of the snap-fit ​​part 703. The snap-fit ​​groove 704 communicates with the through hole 701, and the connection between the two forms a connecting channel 705.

[0027] Combination Figure 5 , Figure 6as well as Figure 7 As shown, the fall arresting wire rope 4 is disposed within the first and second receiving channels. The fall arresting wire rope 4 includes a first connecting section and a second connecting section. The first connecting section is disposed within the first receiving channel, and the second connecting section is disposed within the second receiving channel. A male connector 5 is fixed to the lower end of the first connecting section, and a female connector 6 is fixed to the upper end of the second connecting section. The male connector 5 and the female connector 6 are threaded together. The lower part of the second connecting section is disposed within the through hole 701 and the connecting channel 705 of the safety rope flange 7. A steel sleeve 8 is fixedly connected to the lower end of the second connecting section. The steel sleeve 8 is disposed within the snap-fit ​​groove 704 and engages with the snap-fit ​​groove 704, simplifying the installation process and preventing the fall arresting wire rope 4 from detaching from the safety rope flange 7.

[0028] After installing the connecting rod 2 and the hanging rod 3 on the fan motor 1, the user inserts the first connecting section of the fall arrest wire rope 4 into the first receiving channel along the direction from the lower opening to the upper opening, and fixes the connecting male end 5 to the lower end of the first connecting section. The upper end of the first connecting section can be fixedly connected to the structural components on the ceiling. The user fixes the safety rope flange 7 to the lower end of the connecting rod 2 with several bolts, and then passes the second connecting section of the fall arrest wire rope 4 through the safety rope flange 7 and the second receiving channel in sequence from bottom to top. The lower part of the second connecting section is curved and arranged in the connecting channel 705, and the steel sleeve 8 at the lower end of the second connecting section is arranged in the snap-fit ​​groove 704. Then, the end cap 9 is fixed to the bottom of the safety rope flange 7 with several bolts. This not only ensures the flatness and aesthetics of the bottom end face of the fan motor 1, but also prevents the steel sleeve 8 from detaching from the snap-fit ​​groove 704, improving the safety of the fall arrest wire rope 4. The upper end of the second connecting section is fixedly connected to a female connector 6, and a male connector 5 is threadedly connected to the female connector 6, used to connect the first and second connecting sections. When the connection between the connecting rod 2 and the suspension rod 3 breaks, and the fan motor 1 is about to fall, the fall arresting wire rope 4 is fixed to a structural component on the ceiling at its upper end and to a safety rope flange 7 at its lower end, thus holding the fan motor 1 in place and preventing it from falling and injuring people. Furthermore, the threaded connection between the male connector 5 of the first connecting section and the female connector 6 of the second connecting section facilitates both installation and disassembly, reducing the difficulty of installing the fall arresting wire rope 4.
