[0020] The following further describes the utility model with specific embodiments, referring to Figure 1 —4:

[0021] The installation structure of the suspension rod of a ceiling fan includes a suspension bracket, a base 1, a suspension ball 2 and a suspension rod 3. The base 1 is installed on the suspension bracket. The suspension ball 2 rotates in all directions within the base 1. The upper end of the suspension rod 3 is installed on the suspension ball 2. The suspension bracket includes a bottom plate 4, two vertical side plates 5 connected to the bottom plate 4, and horizontal mounting plates 6 respectively connected to the vertical side plates 5. A horizontal connecting plate 7 is provided between the two vertical side plates 5. A through hole 8 for the suspension rod 3 to pass through is provided on the bottom plate 4. Through slots 9 are respectively provided on the two vertical side plates 5. Vertical connecting plates 10 are provided at both ends of the horizontal connecting plate 7 after passing through the through slots 9 respectively. The vertical connecting plates 10 are fixed to the horizontal connecting plate 7 by welding. A notch one 11 for the suspension rod 3 to pass through is provided on the side wall of the base 1. A notch two 12 communicating with the through hole 8 is provided on the bottom plate 4. The width of the notch two 12 is greater than the diameter of the suspension rod 3. A limiting groove 13 is recessed on the outer peripheral surface of the suspension ball 2. A limiting convex block 14 adapted to the limiting groove 13 is provided on the base 1. The base 1 restricts the suspension ball 2 from rotating around the axis of the suspension rod 3 through the limiting groove 13 and the limiting convex block 14.

[0022] As Figures 1-4 shown, the two vertical side plates 5 of the suspension bracket of the present utility model are pulled by the vertical connecting plates 10 welded thereto. The connection area is large and the strength is high. The two vertical side plates 5 are not easily expanded and deformed outward, and the suspension bracket has a good load-bearing effect. A notch one 11 is provided on the base 1, and a notch two 12 is provided on the bottom plate 4. When installing the suspension ball 2, there is no need to disassemble the suspension rod 3. The suspension rod 3 enters through the notch one 11 and the notch two 12, and then the suspension ball 2 is lowered and installed into the base 1. When disassembling the suspension ball 2, there is no need to disassemble the suspension rod 3. Just lift the suspension ball 2 and then take out the suspension rod 3 from the notch one 11 and the notch two 12, that is, there is no need to disassemble and assemble the suspension rod 3 when disassembling and assembling the suspension ball 2, which is convenient for disassembly and assembly. The base 1 of the present utility model restricts the suspension ball 2 from rotating around the axis of the suspension rod 3 through the limiting groove 13 and the limiting convex block 14. During the operation of the ceiling fan, the suspension ball 2 will not rotate around the axis of the suspension rod 3 relative to the base 1, that is, the suspension rod 3 will not rotate around the axis of the suspension rod 3 relative to the base 1, and the ceiling fan operates stably.

[0023] Compared with directly installing the suspension rod on the ceiling, the vibration during motor startup is directly transmitted to the ceiling, resulting in a large noise. The horizontal mounting plate 6 of the present utility model is installed on the ceiling, and the suspension ball 2 rotates in all directions within the base 1, so that when the ceiling fan starts up, the suspension rod 3 can shake within a certain range relative to the base 1, thereby reducing the vibration during motor startup from being transmitted to the ceiling, thus achieving the purpose of vibration reduction and noise reduction.

[0024] The connection structure between the suspension ball 2 and the suspension rod 3: As Figure 1 、 3As shown, the upper surface of the badminton shuttlecock 2 is concave to form a limiting groove 15. There are two limiting grooves 15 arranged oppositely. A pin shaft 16 is inserted into the boom 3. Both ends of the pin shaft 16 extend out of the boom 3 and are clamped in the corresponding limiting grooves 15. An installation hole is provided on the side wall of the badminton shuttlecock 2, and a threaded hole is provided on the side wall of the boom 3. The rod part of the first screw 17 passes through the installation hole and is screwed to the threaded hole. A gap is left between the installation hole and the rod part of the first screw 17, so that the boom 3 has a certain shaking space relative to the badminton shuttlecock 2, further reducing the transmission of vibration and thus reducing noise.

[0025] In this embodiment, there are two first screws 17, and they are spaced 90°.

[0026] The connection structure between the base 1 and the bottom plate 4: The base 1 is arranged on the bottom plate 4, and the second screw 18 passes through the bottom plate 4 and is screwed to the base 1. The structure is simple, convenient for installation, and the installation is firm and reliable.

[0027] In order to minimize the weight of the base 1 while ensuring the strength of the base 1, the outer side wall of the base 1 is in the shape of a frustum of a cone with a smaller upper part and a larger lower part.

[0028] Furthermore, the horizontal connecting plate 7 and the vertical connecting plate 10 are formed by bending a steel plate. The horizontal connecting plate 7 and the vertical connecting plate 10 are perpendicularly arranged, and the vertical connecting plate 10 is located below the horizontal connecting plate 7. It is convenient for processing and has good connection strength.

[0029] In order to protect the boom installation structure of the present invention and prevent it from being directly exposed, a cover 19 is provided outside the hanger. The cover 19 is hollow and has an opening at the upper end. A gourd-shaped hole 20 is provided at the bottom of the cover 19. The gourd-shaped hole 20 is in an arc shape coaxial with the boom 3. The gourd-shaped hole 20 includes a large hole and an arc-shaped groove communicating with the large hole. The rod part of the third screw 21 passes through the arc-shaped groove and is screwed to the bottom plate 4, and the bottom of the cover 19 is limited between the head of the third screw 21 and the bottom plate 4. The large hole is larger than the diameter of the head of the third screw 21. When disassembling, loosen the third screw 21 and rotate the cover 19, and the cover 19 can be taken out; when installing, align the large hole with the head of the third screw 21 and install the cover 19, rotate the cover 19, and the third screw 21 is stuck in the small hole to complete the installation. The disassembly and installation are convenient and fast.

[0030] Furthermore, the bottom of the cover 19 sinks to form an installation groove 22, and the bottom plate 4 and the base 1 are arranged in the installation groove 22.

[0031] The above embodiments are only one of the preferred embodiments of the present invention, and do not limit the implementation scope of the present invention. Therefore, all equivalent changes made according to the shape, structure, and principle of the present invention should be covered within the protection scope of the present invention.
