Description

Technical Field

[0001] The utility model relates to the field of ceiling fans, in particular to a suspension assembly of a ceiling fan.

Background Art

[0002] In the prior art, the ceiling fan body is relatively fixedly connected to a hanger assembly fixed on the ceiling through a suspension rod provided at its upper end. The specific installation steps are as follows: Pass the power cord through the inside of the suspension rod assembly, fix the suspension rod assembly on the ceiling fan, then lift the ceiling fan and suspend it on the hanger on the ceiling through the suspension rod assembly, and rotate the hanging ball to relatively fixedly connect the hanging ball with the hanger. Thus, the ceiling fan body is relatively fixedly connected to the hanger assembly.

[0003] However, the suspension rod and the hanging ball are connected by a pin. There are two situations. One is that there is a wire harness inside the suspension rod, which will hinder the pin from passing through the suspension rod. The other is that when the power cord and the ground wire pass through the suspension rod, since there is a pin inside the suspension rod, it will hinder the passing of the power cord and the ground wire, especially the power cord and the ground wire with terminal blocks. The installer needs to loosen the fixing screws of the suspension rod assembly, remove the pin, pass the power cord and the ground wire through the suspension rod and the hanging ball, and then reinstall the pin and the fixing screws. This is time-consuming and error-prone. For the above reasons, many fan products are required by customers to pre-pass the power cord through the suspension rod in the factory, aiming to move the action of disassembling and assembling the pin by consumers to the factory. As a result, the processing efficiency of the factory is slow, and the production line also needs to be lengthened.

[0004] In addition, since there is an assembly gap between the suspension rod and the hanging ball and they cannot be tightly meshed, when using the fixing screws to fix the suspension rod, the suspension rod will be forced to deflect to one side, resulting in a decrease in the concentricity of the suspension rod relative to the hanging ball. When the product is running, the yaw will increase. After long-term use, when the ceiling fan rotates, the hanging ball is likely to become loose and unstable through the suspension rod, posing a safety hazard.

[0005] Therefore, the utility model is proposed in view of the problems existing in the prior art.

Detailed Embodiment

[0031] The following will describe the embodiments of the present utility model in detail with reference to the attached Figure 1-8 drawings.

[0032] As Figure 1-3As shown, a suspension assembly of a ceiling fan includes a suspension rod 1 and a suspension ball 2; the upper part of the suspension rod 1 is provided with a limiting protrusion 11 protruding from the side of the suspension rod 1, the limiting protrusion 11 and the suspension rod 1 are integrally formed, and the interior of the suspension rod 1 is provided with a threading channel 12 for passing a power cord 3; the suspension ball 2 is provided with a suspension rod mounting portion 20 for the lower end of the suspension rod 1 to pass from the top to the bottom thereof, the suspension rod mounting portion 20 has a suspension rod passing channel 25 for the lower end of the suspension rod 1 to pass from the top to the bottom thereof, and the suspension rod mounting portion 20 is provided with a limiting bayonet 21 which cooperates with the limiting protrusion 11 to limit the rotation of the suspension rod 1 relative to the suspension ball 2 and prevent the suspension rod 1 and the suspension ball 2 from separating axially.

[0033] When the utility model is in use, the lower end of the suspension rod 1 is passed through the upper part of the suspension rod mounting part 20 of the hanging ball 2 to the lower part of the suspension rod mounting part 20, and the upper part of the suspension rod 1 cooperates with the suspension rod mounting part 20, specifically, the limiting protrusion 11 cooperates with the limiting bayonet 21, so as to limit the rotation of the suspension rod 1 relative to the hanging ball 2 and prevent the suspension rod 1 and the hanger 2 from being separated axially. A threading channel 12 for the power cord 3 to be passed through is provided inside the suspension rod 1, which facilitates the power cord 3 to be passed from the upper part of the suspension rod 1 to the lower part of the suspension rod 1 and connected to the ceiling fan body.

[0034] like Figure 4 and Figure 5 As shown, further, in order to facilitate the power cord 3 to enter the threading channel 12 and the coordination between the suspension rod 1 and the suspension ball 2, the upper portion of the suspension rod 1 is arranged in a trumpet shape; the upper end surface of the limiting protrusion 11 is on the same plane as the upper end surface of the suspension rod 1.

[0035] Furthermore, the number of the limiting protrusions 11 and the limiting slots 21 are two respectively and they are located on the same diameter line respectively.

[0036] Furthermore, the limiting protrusion 11 has a first side surface 111 and a second side surface 112 respectively used for abutting against two side surfaces of the limiting bayonet 21 , and the first side surface 111 and the second side surface 112 are connected to form a V-shaped structure.

The hanging rod 1 is electrically connected to a ground wire 4 through the ground wire terminal 13. The hanging rod mounting portion 20 is further provided with a notch 22 for avoiding the ground wire terminal 13. With such a setting, the ground wire 4 can be directly connected to the ground wire connection terminal 13 at the upper part of the hanging rod 1, instead of necessarily passing the power supply wire 3 and the ground wire 4 through the wire passing channel inside the hanging rod 1 to the lower part of the hanging rod 1 for connection. Therefore, it has the characteristics of being convenient for connecting the ceiling fan body to the power supply wire 3, connecting the ground wire 3 to the ground wire connection terminal 11, and the ceiling fan running smoothly.

[0041] Embodiment 2, as Figure 3-8 shown, on the basis of Embodiment 1, to make the hanging rod 1 and the hanging ball 2 mesh tightly, an elastic bushing 5 is provided between the hanging rod 1 and the hanging ball 2. The outer circumferential surface of the bushing 5 is tapered upward and gradually expanding. The hanging rod mounting portion 20 is provided with a receiving interface 23 for fitting with the bushing 5. The inner circumferential surface of the receiving interface 23 is tapered downward and gradually shrinking. The taper of the inner circumferential surface of the receiving interface 23 matches the taper of the outer circumferential surface of the bushing 5.

[0042] Further, to prevent the bushing 5 from interfering with the limiting bayonet 11, the upper end of the bushing 5 is provided with a bayonet 51 for avoiding the limiting protrusion 11. The number of the bayonets 51 is two and they are respectively on a diameter line.

[0043] Further, to make the bushing 5 adapt to different specifications of the hanging rod 1 and the receiving interface 23, the side surface of the bushing 5 has a longitudinal slotted groove 52, which is easy for the diameter of the bushing 5 to change to match the hanging rod 1 and the receiving interface 23.

[0044] The upper part of the bushing 5 is further provided with a notch 53 for avoiding the ground wire terminal 13

[0045] As Figure 2 and Figure 3 shown, on the basis of the above embodiments, furthermore, to make the connection between the hanging rod 1 and the hanging ball 2 stable and limit the upward radial separation of the hanging rod 1 relative to the hanging ball 2, a limiting member 6 for limiting the axial upward separation of the hanging rod 1 and the hanging ball 2 is further included. The limiting member includes a limiting screw 61; the hanging rod mounting portion 20 is further provided with a limiting threaded hole 24 for cooperating with the limiting screw 61, and the limiting threaded hole 24 is arranged above the limiting bayonet 21.
