Description

Technical Field

[0001] This utility model belongs to the technical field of hanging electric fans, specifically, it relates to a hanging connection structure for an electric fan. Background Technology

[0002] A ceiling fan is a fan that is fixedly installed on the ceiling. It is very effective at cooling down. A ceiling fan is a household appliance that is fixedly installed on the ceiling and uses a motor to drive the fan blades to rotate, thereby generating airflow to achieve the purpose of cooling down.

[0003] Chinese utility model patent CN221879814U discloses a ceiling fan hanging connection structure comprising a connecting rod, a motor, and a support frame. The support frame has an internally fixed mounting ring, the mounting ring has an internally fixed bearing, the first bearing has an internally fixed mounting column, and the upper end of the mounting column has an internally fixed baffle. During installation, the support frame is first installed on the ceiling, and then the nuts are loosened. At this point, the connecting frame tilts under the weight of the structure below, simultaneously causing the mounting column to rotate within the first bearing until the connecting rod, motor, and fan blades are perpendicular to the floor. This allows the fan blades and motor to be in a perpendicular position even when installed on an inclined ceiling, ensuring the airflow is directed downwards and minimizing wear on one side during operation.

[0004] While the aforementioned existing technology allows ceiling fans to be installed on sloping ceilings, the installation and disassembly of the fan blades and the hanging rod are quite complicated, making it even more difficult for operators to install and disassemble them while climbing to a height.

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problem mentioned in the background art that the installation and disassembly of the fan blades and the boom are cumbersome, and even more difficult when operators are at height to install and disassemble them, this utility model adopts the following technical solution.

[0007] A hanging connection structure for an electric fan includes a connecting base, a connecting rod detachably connected to the connecting base, a fixing block detachably connected to the bottom of the connecting rod, multiple fan blades detachably connected to the outer wall of the fixing block, a plug-in rod fixedly connected to the bottom of the connecting rod, a plug-in sleeve rotatably connected to the upper end of the fixing block, a drive motor embedded in the bottom inner side of the plug-in sleeve, the rotating end of the drive motor detachably connected to the upper end of the fan blades, quick-connect components installed on the plug-in rod and the plug-in sleeve, the quick-connect components enabling quick connection between the plug-in sleeve and the plug-in rod, and a quick-release component installed on the outer wall of the plug-in sleeve, the quick-release component enabling quick disassembly between the plug-in sleeve and the plug-in rod.

[0008] Preferably, a vertical adjustment component is installed at the bottom of the connecting base, which makes the connecting rod hang vertically downward.

[0009] Preferably, a length adjustment component is installed on the outer wall of the connecting rod, which adjusts the position of the fan blades in the vertical state.

[0010] Preferably, the quick-installation assembly includes, but is not limited to, elastic triangular plates and limiting through slots. The outer wall of the plug rod is provided with multiple elastic triangular plates, each elastic triangular plate extending outward elastically and being able to be pressed inward. The outer wall of each elastic triangular plate is provided with a downward inclined surface. The elastic triangular plates extend further near the upper end. The outer wall of the plug sleeve is provided with multiple limiting through slots.

[0011] Preferably, the quick-release assembly includes a sliding sleeve, a sliding block, a connecting plate, and an arc-shaped plate. The outer wall of the insert sleeve is fitted with the sliding sleeve. The inner wall of the sliding sleeve near the upper end is fixedly connected with a sliding block that is inserted into each limiting through slot. The outer walls of the sliding sleeve are fixedly connected with connecting plates on both sides. The outer end of each connecting plate near the outside is damped and rotatably connected with an arc-shaped plate. The upper outer wall of the insert sleeve is fixedly connected with a limiting disc.

[0012] Preferably, the upper ends of the fixing block are fixedly connected to the two sides of a second U-shaped frame with the opening facing outward, and the arc-shaped plate is stuck inside the second U-shaped frame.

[0013] Preferably, the vertical adjustment assembly includes a first U-shaped frame and fixing bolts.

Each elastic triangle plate retracts inward when inserted into the socket sleeve, and automatically pops outward after each elastic triangle plate aligns with each limiting through slot, thus achieving a quick assembly effect.

[0017] 2. By rotating the arc-shaped plate in the quick-release assembly outward, the operator holds the arc-shaped plate with both hands and lifts it upward. The sliding sleeve moves upward, causing each sliding block to slide upward inside the limiting through groove, thereby causing each elastic triangular plate to retract inward. This allows the insertion sleeve to be removed. The position of the sliding sleeve can be limited by the limiting disc, thus achieving the effect of quick disassembly. Furthermore, the arc-shaped plate makes installation easier. After installation, each arc-shaped plate can be rotated inward so that it is not visible during daily use.

[0018] 3. The second U-shaped frame can hold the curved plate in place, preventing it from swinging outwards.

[0019] 4. By loosening the fixing bolts in the vertical adjustment assembly, the connecting base is installed on the ceiling, and the connecting rod is made to point vertically downward by gravity. By tightening the fixing bolts, the position of the connecting rod can be fixed, so that the fan blades can blow air vertically downward when the ceiling is tilted or uneven.

[0020] 5. Adjust the extension length of the sliding plate by loosening the fastening bolts in the length adjustment assembly. Tighten the fastening bolts to generate friction between the threaded end of the fastening bolts and the outer wall of the sliding plate, thereby fixing the extension length of the sliding plate.

The present invention provides the following embodiments.

[0032] like Figure 1 As shown, this is a schematic diagram of a hanging connection structure for an electric fan according to a preferred embodiment of the present invention. The hanging connection structure for an electric fan in this embodiment includes a connecting base 100, a connecting rod 200 detachably connected to the connecting base 100, a fixing block 300 detachably connected to the bottom of the connecting rod 200, and a plurality of fan blades 301 detachably connected to the outer wall of the fixing block 300. In this embodiment, the fixing block 300 rotates to cooperate with each fan blade 301, thereby enabling downward airflow.

[0033] like Figure 2As shown, this is a schematic diagram of the adjustment component structure in this embodiment. The bottom of the connecting base 100 is fixedly connected to a first U-shaped frame 101 with its opening facing downwards. The upper end of the connecting rod 200 is telescopically connected to a sliding plate 201. The sliding plate 201 is inserted into the opening of the first U-shaped frame 101. A fixing bolt 102 is detachably connected to the first U-shaped frame 101. In this embodiment, by loosening the fixing bolt 102, the connecting base 100 is installed on the ceiling so that the connecting rod 200 is vertically downwards by gravity. By tightening the fixing bolt 102, the position of the connecting rod 200 can be fixed, so that the fan blade 301 can blow air vertically downwards when the ceiling is tilted or uneven.

[0034] It is worth noting that the first U-shaped frame 101 and the fixing bolt 102 mentioned above are the vertical adjustment components in this embodiment. The vertical adjustment components include, but are not limited to, the first U-shaped frame 101 and the fixing bolt 102. Any component that can make the connecting rod 200 vertically downward can be applied to this embodiment.

[0035] like Figure 2 As shown, in order to adjust the position of the fan blade 301 according to the height of the room, in this embodiment, the outer wall of the connecting rod 200 is threaded with a fastening bolt 202. The threaded end of the fastening bolt 202 contacts the outer wall of the sliding plate 201. The extension length of the sliding plate 201 can be adjusted by loosening the fastening bolt 202, and the extension length of the sliding plate 201 can be fixed by tightening the fastening bolt 202 so that the threaded end of the fastening bolt 202 generates friction with the outer wall of the sliding plate 201.

[0036] It is worth noting that the fastening bolt 202 mentioned above is the length adjustment component in this embodiment. The length adjustment component includes, but is not limited to, the fastening bolt 202. Any component that can fix the extension length of the fastening bolt 202 can be applied to this embodiment.

[0037] like Figure 3As shown, this is a schematic diagram of the quick-assembly component structure in this embodiment. A plug-in rod 203 is fixedly connected to the bottom of the connecting rod 200. Multiple elastic triangular plates 204 are provided on the outer wall of the plug-in rod 203. Each elastic triangular plate 204 extends outward elastically and can be pressed inward. The outer wall of each elastic triangular plate 204 has a downward-sloping surface. The elastic triangular plate 204 extends further near its upper end. A plug-in sleeve 302 is rotatably connected to the upper end of the fixing block 300. The bottom of the inner side of the plug-in sleeve 302 is embedded... A drive motor is installed, and the rotating end of the drive motor is detachably connected to the upper end of the fan blade 301. The outer wall of the insertion sleeve 302 is provided with multiple limiting through grooves 303. In this embodiment, during installation, the insertion sleeve 302 is moved upward from below the insertion rod 203. When each elastic triangle plate 204 is inserted into the interior of the insertion sleeve 302, it retracts inward. After each elastic triangle plate 204 corresponds to each limiting through groove 303, it automatically pops outward, thereby achieving the effect of rapid assembly.

[0038] It is worth noting that the elastic triangle plate 204 and the limiting through groove 303 mentioned above are quick-installation components in this embodiment. Quick-installation components include, but are not limited to, the elastic triangle plate 204 and the limiting through groove 303. Any component that can quickly connect the plug sleeve 302 and the plug rod 203 can be applied to this embodiment.

[0039] like Figure 3 as well as Figure 4 As shown, this is a schematic diagram of the quick-release component structure in this embodiment. A sliding sleeve 305 is fitted onto the outer wall of the insertion sleeve 302. A sliding block, inserted into each limiting through-slot 303, is fixedly connected to the inner wall of the sliding sleeve 305 near its upper end. Connecting plates 306 are fixedly connected to both sides of the outer wall of the sliding sleeve 305. An arc-shaped plate 307 is damped and rotatably connected to the outer end of each connecting plate 306 near its outer side. A limiting disc 304 is fixedly connected to the upper outer wall of the insertion sleeve 302. In this embodiment, during disassembly, each arc-shaped plate 307 is rotated outwards, and the operator uses both hands to separate the components. Do not hold the curved plate 307 and lift it upwards. Move the sliding sleeve 305 upwards so that each sliding block slides upwards inside the limiting through groove 303, thereby causing each elastic triangle plate 204 to retract inwards. This allows the insertion sleeve 302 to be removed. The limiting disc 304 can limit the position of the sliding sleeve 305, thus achieving a quick disassembly effect. Furthermore, the curved plate 307 makes installation easier. After installation, each curved plate 307 can be rotated inwards so that it is not visible during daily use.

[0040] It is worth noting that the aforementioned sliding sleeve 305, sliding block, connecting plate 306, and arc plate 307 are quick-release components in this embodiment.

[0041] like Figure 4 As shown, in order to prevent the arc plate 307 from being thrown outward during the rotation of the fixing block 300, in this embodiment, the upper ends of the fixing block 300 are fixedly connected with the second U-shaped frame 308 with the opening facing outward. The arc plate 307 is stuck inside the second U-shaped frame 308. In this embodiment, the arc plate 307 can be stuck by the second U-shaped frame 308 to prevent the arc plate 307 from being thrown outward.
