Description

Technical Field

[0001] This utility model relates to the technical field of ventilation equipment, and in particular to a fan with a fall-prevention safety structure. Background Technology

[0002] In daily life and work settings, suspended fans (such as ceiling fans and wall-mounted fans) are widely used in various indoor environments due to their advantages such as good air circulation and small installation space requirements. However, traditional suspended fans have the following significant safety hazards and functional limitations during long-term use: The installation structure of traditional suspended fans relies on the rigid connection between the connecting seat on the fixed shaft and the mounting part (ceiling mount or hanging rod), with the core load-bearing components being bolts, clips, and other connecting parts. As usage time increases, these connecting parts are prone to loosening due to vibration, changes in ambient humidity, and material aging. In addition, the centrifugal force generated by the rotation of the fan blades during operation continuously applies lateral loads to the connection nodes between the fixed shaft and the mounting part, further accelerating the wear and loosening of the connecting parts. Once the connecting parts fail, the entire fan (including the drive motor and fan blades) will fall from a height, potentially injuring people below or damaging furniture, thus posing a threat to the user's personal safety. Utility Model Content

[0023] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0024] Reference Figures 1 to 6 A fan with a fall-prevention safety structure includes a mounting part 1 for fixing to a wall, a fixed shaft 2 connected to the mounting part 1, a drive motor 3 rotatably connected to the fixed shaft 2, and several fan blades 4 fixed to the drive motor 3. A fall-prevention rope 5 is connected to the upper or lower end of the fixed shaft 2. A connecting structure 6 is provided between the lower end of the fall-prevention rope 5 and the fixed shaft 2 to securely connect the two. The upper end of the fall-prevention rope 5 is fixed to the mounting part 1 or the wall. Thus, if the connecting structure 6 between the mounting part 1 and the fixed shaft 2 fails, the fall-prevention rope 5 can hold the drive motor 3, preventing the drive motor 3 and its connected components from falling and injuring people below or damaging furniture, thereby improving the safety of the fan.

[0025] In this design, the fixed shaft 2 has a hollow interior forming a first through hole 21. The fixed shaft 2 includes a first end 22 located at its upper end and extending above the drive motor 3, and / or a second end 23 located at its lower end and extending below the drive motor 3. The lower end of the fall arresting rope 5 passes through the first through hole 21 and connects to either the first end 22 or the second end 23. This hollow design of the fixed shaft 2 creates a first through hole 21, providing a concealed passage for the fall arresting rope 5 and preventing it from being exposed. Simultaneously, the extended design of the first end 22 and the second end 23 provides sufficient operating space for connecting the fall arresting rope 5, facilitating rope fixation by installers and reducing assembly difficulty.

[0026] In this design, the connecting structure 6 includes a threading hole 61 located on the first end 22 or the second end 23 for the fall arrestor rope 5 to pass through, a cable sleeve 62 located outside the fixed shaft 2 for the fall arrestor rope 5 to pass through, and a locking screw 63 located on the cable sleeve 62 to lock the fall arrestor rope 5 within the cable sleeve 62. Preferably, the threading hole 61 includes a first threading hole 611 located on one side of the fixed shaft 2 and a second threading hole 612 located on the fixed shaft 2 opposite to the first threading hole 611. Thus, the lower end of the fall arrestor rope 5 first passes through the first threading hole 611 inside the fixed shaft 2, then passes through the cable sleeve 62 and returns to the inside of the fixed shaft 2 through the second threading hole 612, then passes through the first threading hole 611 inside the fixed shaft 2, and finally inserts into the cable sleeve 62 and is locked in place by the locking screw 63 on the cable sleeve 62. This effectively prevents the fall arresting rope 5 from slipping off the fixed shaft 2, ensuring the reliability of the connection between the fall arresting rope 5 and the fixed shaft 2. Simultaneously, the symmetrical design of the first threading hole 611 and the second threading hole 612 ensures uniform stress distribution on the rope, avoiding the risk of breakage due to localized stress concentration. Of course, there can be one or more threading holes 61; and two locking screws 63 are respectively located on both sides of the cable sleeve 62 to lock the fall arresting rope 5 inserted therein.

[0027] In this solution, the upper end of the fall arrest rope 5 is provided with a connector 51. The connector 51 includes a connecting plate 511 for fixing to the installation part 1 or the wall. The connecting plate 511 is provided with a fixing hole 512 to accommodate various fixing methods such as expansion bolts and self-tapping screws, so as to facilitate fixing the upper end of the fall arrest rope 5 to the installation part 1 or the wall.

[0028] In this design, a connecting seat 7 is provided between the fixed shaft 2 and the mounting part 1 to connect the two. The connecting seat 7 serves as a transitional connection between the fixed shaft 2 and the mounting part 1, and can be quickly assembled and disassembled by means of threads or snap-fit ​​connections. The connecting seat 7 is provided with a second through hole 72 that communicates with the first through hole 21, thereby providing a continuous passage for the fall arresting rope 5 to pass through, ensuring that the fall arresting rope 5 can extend from the fixed shaft 2 to the mounting part 1 or the wall.

[0029] In this solution, the mounting part 1 includes a ceiling mount 11 connected to the connecting seat 7 and fixed to the wall. The interior of the ceiling mount 11 communicates with the second through hole 72, so that the fan can be used as a ceiling fan.

[0030] In this solution, the mounting part 1 includes a hanging rod 12 connected to the connecting seat 7 and a ceiling seat 13 fixed to the wall at the upper end of the hanging rod 12. The hanging rod 12 is provided with a third through hole 121 that allows the interior of the ceiling seat 13 to communicate with the second through hole 72, so that the fan can be used as a ceiling fan.

[0031] In this solution, a light-emitting part 8 is connected to the second end 23. The light-emitting part 8 includes a fixing plate 81 disposed on the second end 23, a lamp cover 82 disposed on the fixing plate 81, and a lamp wick 83 disposed inside the lamp cover 82. The first through hole 21 communicates with the interior of the lamp cover 82, so that the power line of the lamp wick 83 can be routed through the first through hole 21 to hide it and avoid exposure.

[0032] In this design, the fall arrestor rope 5 is a steel wire rope, ensuring that it can support the weight of the fan and eliminate the risk of falling. Furthermore, the surface of the steel wire rope is galvanized to improve its corrosion resistance and prevent rusting caused by humid environments over long-term use.

[0033] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
