DETAILED DESCRIPTION

[0029] The specific implementation of the utility model will be described below with reference to the accompanying drawings of the specification.

[0030] As a specific embodiment, the easily transportable ceiling fan device of the embodiment of the utility model includes a motor 1, an outer cover 2, blades 3 and mounting screws 4, and the motor shaft of the motor 1 is connected to a suspension rod 19. The top of the suspension rod 19 is usually connected to a connecting frame 191, and the connecting frame 191 can be fixed to the top wall of the room by screws, so that the motor 1 is suspended by the connecting frame 191. Usually, a connecting frame cover 192 surrounding the connecting frame 191 is also provided at the top of the suspension rod 19 to achieve dustproof, aesthetic and other functions.

[0031] The outer cover 2 includes a motor connector 29 and an overall annular mounting side wall 21, and the motor 1 is fixedly connected to the motor connector 29. It is easy to understand that the rotation of the motor 1 can drive the outer cover 2 and the blades 3 to rotate to achieve blowing.

[0032] An installation protrusion groove 211 is formed on the outer side surface of the installation side wall 21 , and a threaded hole 213 is formed on the bottom wall of the installation protrusion groove 211 .

[0033] A side wall top hole 212 is formed at the top of the installation side wall 21 , facing the threaded hole 213 and penetrating into the installation protruding groove 211 .

[0034] One end of the blade 3 is a mounting end 31 , and the mounting end 31 is provided with a mounting ear 311 .

[0035] The mounting ear 311 is embedded in the mounting protruding groove 211, and the mounting screw 4 passes through the mounting ear 311 and is screwed into the threaded hole 213, and the screw head of the mounting screw 4 abuts against the top surface of the mounting ear 311. It should be noted that the mounting screw 4 abuts against the top surface of the mounting ear 311 through a gasket (not shown in the drawings), which also means that the screw head of the mounting screw 4 abuts against the top surface of the mounting ear 311.

[0036] The working principle is that before transportation, the motor 1 is usually assembled with the outer cover 2, the suspension rod 19 is separated from the motor 1, but the blade 3 is separated from the outer cover 2. At this time, the space occupied by a single part is small, which is convenient for transportation.

[0037] When the blade 3 is transported to the end user and needs to be used, the mounting ears 311 are respectively embedded in the mounting protruding grooves 211, and a screwdriver is passed through the top hole 212 of the side wall to rotate the mounting screw 4, so that the mounting screw 4 passes through the mounting ears 311 and is screwed into the threaded hole 213, and the screw head of the mounting screw 4 abuts against the top surface of the mounting ears 311, so that the blade 3 is fixedly connected to the mounting side wall 21. Compared with the traditional method of fixing the blade 3, the top surface of the mounting ear 311 is abutted downward by the screw head of the mounting screw 4 and is clamped downward, which can ensure that the blade 3 is not easy to shake.

[0038] As one of the specific embodiments, it also includes a motor cover 193 mounted on the suspension rod 19, and when viewed from above, the side wall top hole 212 is completely located in the motor cover 193. Usually, the motor cover 193 is an inverted bowl shape, and the bottom end of the motor cover 193 is close to the top end of the installation side wall 21, thereby forming a roughly closed space, thereby achieving dust prevention.

[0039] As one of the specific implementations, Fig.10 As shown, the side surface of the mounting end 31 is a cylindrical surface with the same diameter as the mounting side wall 21, and the mounting ear 311 is located in the middle of the side surface of the mounting end 31. When the mounting end 31 is embedded in the mounting protruding groove 211, the side surface of the mounting end 31 above the mounting ear 311 and the side surface of the mounting end 31 below are completely fitted with the mounting side wall 21, which can ensure that the blade 3 is installed more firmly.

[0040] As one of the specific embodiments, it also includes a metal threaded sleeve 214, which is cylindrical in shape and has a side wall extending outward to form a plurality of external protruding teeth 215 arranged along the axis of the threaded sleeve 214 (i.e., the cross section of the external protruding teeth 215 intercepted by a plane perpendicular to the axis of the threaded sleeve 214 is triangular); the outer cover 2 is made of wood, and a threaded sleeve hole 217 is opened on the bottom wall of the mounting protruding groove 211; the threaded hole 213 is the center hole of the threaded sleeve 214; the side wall top hole 212, the threaded sleeve hole 217, the threaded sleeve 214 and the external protruding teeth 215 are all completely located in the side wall top hole 212 when viewed from above. Usually, the blade 3 is also made of wood. During assembly, the threaded sleeve 214 is passed through the top hole 212 of the side wall and placed on the bottom wall of the mounting protruding groove 211. At this time, the threaded sleeve 214 is facing the threaded sleeve hole 217. Then, a cylindrical top column or the like passes through the top hole 212 of the side wall to knock the threaded sleeve 214, so that the threaded sleeve 214 moves downward. In this process, the outer convex teeth 215 also move along the threaded sleeve 214 and are embedded in the side wall of the threaded sleeve hole 217 until the top surface of the threaded sleeve 214 is flush with the bottom wall of the mounting protruding groove 211. The threaded sleeve 214 is fixed to the bottom wall of the mounting protruding groove 211, and the bottom wall of the mounting protruding groove 211 is provided with a threaded hole 213. The threaded hole 213 of wood is easy to slip and reduce the fastening effect of the mounting screw 4. The above structure facilitates the production of the outer cover 2 while ensuring the fastening effect of the mounting screw 4.

[0041] As one of the specific implementations, the motor connector 29 is annular and fixed to the inner wall of the mounting side wall 21, and the bottom end surface of the motor 1 is fixedly connected to the motor connector 29, for example, a screw passes through the motor connector 29 and is screwed into the motor 1, so that the motor 1 is fixedly connected to the motor connector 29.

[0042] As one of the specific implementations, the motor connector 29 is provided with an exposed opening 216 exposed from the top of the motor connector 29, the exposed opening 216 is communicated with the mounting protrusion groove 211, and the mounting ear 311 is embedded in the exposed opening 216. Without increasing the thickness of the motor connector 29, the length of the mounting ear 311 is extended into the motor connector 29, which can ensure that the blade 3 is mounted more firmly.

[0043] As one of the specific implementations, the thickness of the threaded sleeve 214 is smaller than the thickness of the threaded sleeve hole 217. Fig.10 As shown, a gap is inevitably formed between the bottom end of the threaded sleeve 214 and the bottom end of the threaded sleeve hole 217. The gap accommodates wood chips and the like formed when the outer protruding teeth 215 abut against the side wall of the threaded sleeve hole 217, and can ensure that the top of the threaded sleeve 214 is flush with the bottom wall of the mounting protruding groove 211, and the mounting ear 311 will not be blocked by the top of the threaded sleeve 214 when it is embedded in the mounting protruding groove 211, and the mounting ear 311 can be easily embedded in the mounting protruding groove 211.

[0044] As one of the specific embodiments, it also includes a lighting device 9, which is fixed to the motor shaft (not shown in the drawings) below the motor 1 and is close to the bottom end of the mounting side wall 21. Generally, the lighting device 9 includes a lighting carrier (not shown in the drawings) fixedly connected to the motor shaft below the motor 1, on which an LED light board and a light-transmitting lampshade surrounding the LED light board are fixedly arranged, so as to realize lighting through the light emitted by the lighting device 9.
