The battery module of the power bank is electrically connected to the fan.

[0004] One of the aforementioned multi-functional portable fans allows the user to hold the umbrella handle by attaching the casing to a ring and passing their fingers through the ring, freeing up the palm area for gripping the handle. However, during use, the fingers are wearing the ring, and when gripping the handle, the handle can cause discomfort to the palm, reducing comfort. Utility Model Content

[0005] To address the aforementioned issues, this application provides a plastic housing for a portable fan.

[0006] The portable fan plastic housing provided in this application adopts the following technical solution:

[0007] A portable fan plastic housing includes a fan body with a mounting assembly for easy placement. The mounting assembly includes a U-shaped frame on one side of the fan body, and a telescopic assembly for adjusting the distance between the U-shaped frame and the fan body. The U-shaped frame contains two clamping plates, and sliding grooves are formed at the upper and lower ends of one side wall of the U-shaped frame. A bidirectional screw is rotatably connected to each of the sliding grooves. Sliders are fixedly connected to the upper and lower ends of the side wall of the clamping plates near the bidirectional screws. The sliders are slidably disposed in the sliding grooves and threadedly connected to the bidirectional screws. The U-shaped frame is provided with a rotating assembly for rotating the bidirectional screws.

[0008] By adopting the above technical solution, during use, the rotating component drives the bidirectional screw to rotate, causing the sliders to move away from each other and the clamping plates to move away from each other. Then, the U-shaped frame is clamped onto the umbrella handle, so that the two clamping plates are located on both sides of the umbrella handle. Then, by rotating the component, the two clamping plates are brought closer together to clamp the umbrella handle, so that the fan body is installed on the umbrella handle for use. This avoids the problem of the umbrella handle and the finger ring easily irritating the palm when holding the umbrella handle, which would reduce comfort.

[0009] Preferably, the telescopic assembly includes a connecting pipe fixedly connected to the top of the fan body, a connecting block fixedly connected to the top of the U-shaped frame, a connecting rod fixedly connected to the side wall of the connecting block near the connecting pipe, the end of the connecting rod away from the connecting block being slidably disposed inside the connecting pipe, a locking bolt being provided on the upper surface of the connecting pipe near the connecting block, the screw end of the locking bolt being located inside the connecting pipe and abutting against the connecting rod, and the locking bolt being threadedly connected to the connecting pipe.

[0010] By adopting the above technical solution, after the fan body is installed on the umbrella handle, the connecting rod slides in the connecting tube by pulling the fan body, and then the locking bolt is rotated to make the locking bolt abut against the connecting rod to fix the fan body.

[0011] Preferably, the rotating assembly includes two sprockets disposed on one side of the U-shaped frame, the sprockets being fixedly connected to one end of the bidirectional screw, and chains being mounted on the two sprockets.

[0012] By adopting the above technical solution, rotating one of the sprockets causes the chain to drive the other sprocket to rotate, which in turn drives the two bidirectional screws to rotate simultaneously, making it easier to move the two clamps stably.

[0013] Preferably, a protective cover is fixedly connected to one side wall of the U-shaped frame, the sprocket and the chain are both located inside the protective cover, a rotating disk is provided on one side wall of the protective cover, a rotating rod is fixedly connected to one side wall of the rotating disk, and the end of the rotating rod away from the rotating disk passes through the protective cover and is fixedly connected to one of the sprockets.

[0014] By adopting the above technical solution, the protective cover can protect the sprocket and chain, preventing hair or other objects from getting stuck during use, while the rotating disc facilitates the rotation of the sprocket.

[0015] Preferably, the two clamping plates are fixedly connected to the opposite sidewalls with elastic rubber pads to improve clamping stability.

[0016] By adopting the above technical solution, the stability of the clamp holding the umbrella handle can be improved by using the elastic rubber pad, while reducing the pressure on the umbrella handle when the clamp is holding it, thus preventing the umbrella handle from being deformed.

[0017] Preferably, a guide tube is fixedly connected to the bottom end of the fan body, a fixing block is fixedly connected to the bottom end of the U-shaped frame, and a guide rod is fixedly connected to the side wall of the fixing block near the guide tube, the guide rod being slidably disposed inside the guide tube.

[0018] By adopting the above technical solution, the stability of the fan body during movement can be improved through the setting of guide tubes, fixing blocks, and guide rods.

[0019] Preferably, the inner sidewalls of the guide tube are provided with limiting grooves, and the two ends of the guide rod away from the fixed block are fixedly connected to limiting blocks, which are slidably disposed in the limiting grooves.

[0020] By adopting the above technical solution, the setting of the limiting groove and the limiting block can prevent the fan body from disconnecting from the U-shaped frame when adjusting the position of the fan body, thus preventing the fan body from falling and being damaged.

[0021] Preferably, a U-shaped handle is fixedly connected to the side wall of the fan body away from the U-shaped frame, and a rubber sleeve is fitted on the U-shaped handle.

[0022] By adopting the above technical solution, the U-shaped handle makes it easy to hold the fan body, while the rubber sleeve can improve the comfort of holding it.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. This application utilizes the cooperative arrangement of structures such as a U-shaped frame, clamping plates, and a bidirectional screw. During use, the rotating component drives the bidirectional screw to rotate, causing the sliders to move away from each other and the clamping plates to move away from each other. Then, the U-shaped frame is clamped onto the umbrella handle, placing the two clamping plates on both sides of the umbrella handle. The rotating component then brings the two clamping plates closer together, clamping the umbrella handle and allowing the fan body to be mounted on the umbrella handle. This design minimizes the problem of the umbrella handle and finger ring causing discomfort to the palm when holding the umbrella handle.

[0025] 2. After installing the fan body on the umbrella handle, pull the fan body to slide the connecting rod in the connecting tube, then turn the locking bolt to make the locking bolt abut against the connecting rod to fix the fan body. The position of the fan body can be adjusted for easy use. Attached Figure Description

Two bidirectional screws 5 are provided and respectively rotatably connected in the sliding grooves 4. Four sliders 6 are provided and respectively fixedly connected to the upper and lower ends of the side wall of the two clamping plates 3 near the bidirectional screws 5. The sliders 6 are respectively slidably set in the sliding grooves 4 and threadedly connected to the bidirectional screws 5. A rotating component for rotating the bidirectional screws 5 is provided on U-shaped frame 2.

[0035] Reference Figure 1 and Figure 2The telescopic assembly includes a connecting pipe 7 fixedly connected to the top of the fan body 1, a connecting block 8 fixedly connected to the top of the U-shaped frame 2, a connecting rod 9 fixedly connected to the side wall of the connecting block 8 near the connecting pipe 7, and the end of the connecting rod 9 away from the connecting block 8 slidably disposed inside the connecting pipe 7. A locking bolt 10 is provided on the upper surface of the connecting pipe 7 near the connecting block 8. The screw end of the locking bolt 10 is located inside the connecting pipe 7 and abuts against the connecting rod 9. The locking bolt 10 is threadedly connected to the connecting pipe 7. After the fan body 1 is installed on the umbrella handle, by pulling the fan body 1, the connecting rod 9 slides in the connecting pipe 7. Then, the locking bolt 10 is rotated to abut against the connecting rod 9, thereby fixing the fan body 1. The position of the fan body 1 can be adjusted for convenient use.

[0036] Reference Figure 1 and Figure 2 The rotating assembly includes two sprockets 11 located on one side of the U-shaped frame 2. The sprockets 11 are fixedly connected to one end of the bidirectional screw 5. A chain 12 is installed on the two sprockets 11. By rotating one of the sprockets 11, the chain 12 drives the other sprocket 11 to rotate, which can simultaneously drive the two bidirectional screws 5 to rotate, making it convenient for the two clamps 3 to move stably.

[0037] Reference Figure 1 and Figure 2 A protective cover 13 is fixedly connected to one side wall of the U-shaped frame 2. The sprocket 11 and the chain 12 are both located inside the protective cover 13. A rotating disk 14 is provided on one side wall of the protective cover 13. A rotating rod 15 is fixedly connected to one side wall of the rotating disk 14. The end of the rotating rod 15 away from the rotating disk 14 passes through the protective cover 13 and is fixedly connected to one of the sprockets 11. The protective cover 13 can protect the sprocket 11 and the chain 12 to prevent hair or other objects from getting stuck during use. At the same time, the rotating disk 14 can easily drive the sprocket 11 to rotate.

[0038] Reference Figure 1 and Figure 2 On the opposite side wall of the two clamping plates 3, there are elastic rubber pads 16 for improving clamping stability. The elastic rubber pads 16 can improve the stability of the clamping plates 3 in clamping the umbrella handle, and at the same time reduce the pressure on the umbrella handle when the clamping plates 3 clamp the umbrella handle, preventing the umbrella handle from being deformed.

[0039] Reference Figure 1 and Figure 3 A guide tube 17 is fixedly connected to the bottom of the fan body 1, and a fixing block 18 is fixedly connected to the bottom of the U-shaped frame 2. A guide rod 19 is fixedly connected to the side wall of the fixing block 18 near the guide tube 17. The guide rod 19 is slidably disposed inside the guide tube 17.

Limiting blocks 21 are fixedly connected to both sides of the end of the guide rod 19 away from the fixing block 18. The limiting blocks 21 are slidably set in the limiting grooves 20. By setting the limiting grooves 20 and the limiting blocks 21, the fan body 1 can be prevented from disconnecting from the U-shaped frame 2 when adjusting the position of the fan body 1, which would cause the fan body 1 to fall and be damaged.

[0041] Reference Figure 1 A U-shaped handle 22 is fixedly connected to the side wall of the fan body 1 away from the U-shaped frame 2. A rubber sleeve 23 is fitted on the U-shaped handle 22. The U-shaped handle 22 makes it easy to hold the fan body 1, and the rubber sleeve 23 can improve the comfort of holding it.

[0042] The implementation principle of the portable fan plastic shell in this application embodiment is as follows: In use, the rotating disk 14 drives the sprocket 11 to rotate, causing the chain 12 to drive another sprocket 11 to rotate, and simultaneously driving the two bidirectional screws 5 to rotate, causing the sliders 6 to move away from each other, and causing the clamping plates 3 to move away from each other. Then, the U-shaped frame 2 is clamped on the umbrella handle, so that the two clamping plates 3 are located on both sides of the umbrella handle. Then, by rotating the rotating disk 14, the two clamping plates 3 are brought closer together, clamping the umbrella handle, so that the fan body 1 is installed on the umbrella handle for use. At the same time, by pulling the fan body 1, the connecting rod 9 slides in the connecting tube 7. Then, the locking bolt 10 is rotated, so that the locking bolt 10 abuts against the connecting rod 9, fixing the fan body 1. The position of the fan body 1 can be adjusted for convenient use, and the problem of the umbrella handle and finger ring easily irritating the palm when holding the umbrella handle, thus reducing comfort, is avoided.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
