Description

Technical Field

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

[0002] The fan is used to blow air. In order to facilitate use and reduce space occupied, the fan can be hung on the ceiling to form a ceiling fan.

[0003] See Figure 1 As shown, in the ceiling fan suspension structure currently used by the applicant, a hollow hanging tube 1 is usually used as a load-bearing structure. In the design of the hanging tube, two through holes are opened on the side walls at the upper and lower ends of the hanging tube 1, and a single cross pin 1' is used as a structural connection between the upper and lower ends. Since the hollow hanging tube needs to pass the motor leads and the lamp leads (for ceiling fan lamps), although the leads are slender, in order to facilitate the electrical connection of the leads, glue plugs 11' are usually provided at the ends of the leads, and the setting of the cross pin 1' will block the two lead glue plugs 11' of the motor and the lamp, so that consumers need to perform secondary assembly of the hanging tube, that is, first remove the connection between the hanging ball 3 and the hanging tube 1, and then pass the motor leads and the lamp leads with glue plugs, and then assemble the hanging ball 3 and the hanging tube 1 again with the cross pin 1'. The assembly workload is large, and it may cause consumers to produce abnormal noise or poor swing of the fan due to poor assembly.

[0004] Therefore, it is necessary to improve and optimize the existing ceiling fan suspension structure. Utility Model Content

DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solution and advantages of the utility model more clear, the embodiments of the utility model will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments described below can be combined with each other arbitrarily without conflict.

[0043] Many different implementations or examples are provided below to implement the structure of the present utility model.

[0044] See also Figure 2-Figure 15The first aspect of the utility model provides a ceiling fan, including a hanging tube 1, which is generally a metal pipe to ensure that it has sufficient strength. The hanging tube 1 is hollow to form a wire hole 11; a fan body 2, which is connected and fixed to the lower end of the hanging tube 1. The specific connection method between the fan body 2 and the hanging tube 1 is a well-known technology in the art and will not be described here. The fan body 2 can be a separate fan, or it can include a fan and a lighting component to form a fan lamp; a hanging ball 3, which is generally a metal part, connected and fixed to the upper end of the hanging tube 1, and a sleeve hole 31 is provided on the hanging ball 3. The upper end of the hanging tube 1 is inserted into the sleeve hole 31, and the side of the hanging tube 1 A pin 4 is arranged on the wall. There are multiple pins 4. In the present embodiment, there are two pins 4 arranged at 180 degrees. The hanging tube 1 is suspended on the hanging ball 3 by the pin 4. The pin 4 does not extend into the wire hole 11. At this time, the pin can be welded to the outer wall of the hanging tube 1, or the pin can be integrally formed on the outer wall of the hanging tube 1. It can be understood that the pin can also be fixed to the outer wall of the hanging tube 1 by other well-known technologies. Since the pin 4 does not extend into the wire hole 11, there is obviously no problem of the pin blocking the wire glue insertion. Consumers can directly insert the wire glue through the wire hole 11 without disassembling the hanging ball and the hanging tube. In other embodiments, such as Figure 6 , Figure 7 , Fig.14 As shown, the pin shaft 4 extends into the wire hole 11 to form an insertion end, and the insertion ends of the plurality of pin shafts 4 are spaced apart. In this embodiment, two pin shafts are used to replace Figure 1 The existing single horizontal pin structure shown in the figure makes the extending ends of the two pin shafts 4 spaced apart but not touching each other, thereby forming an avoidance space between the extending ends of the two pin shafts, thereby allowing the lead glue to be inserted through, and the consumer can directly insert the lead glue through the wire hole without disassembling the hanging ball and the hanging tube.

[0045] like Figure 6 , Figure 7 and Fig.14 As shown, in some embodiments of the utility model, a pin hole is provided on the side wall of the hanging pipe 1, and the pin shaft 4 is riveted in the pin hole, which not only simplifies the structure of the hanging pipe 1, but also makes the connection of the pin shaft 4 on the hanging pipe reliable; in other embodiments, the pin shaft 4 can also be welded in the pin hole; thus, the pin shaft 4 and the hanging pipe 1 form a whole, which eliminates the process of installing the pin shaft for consumers, making the assembly of the ceiling fan simpler and faster.

[0046] See Figure 8 As shown, in some embodiments of the utility model, a U-shaped groove 32 is provided on the hole wall of the sleeve hole 31, and the pin shaft 4 is inserted into the U-shaped groove 32. The U-shaped groove 32 can guide and limit the pin shaft 4, thereby facilitating the assembly of the hanging tube 1 pre-installed with the pin shaft 4 on the hanging ball 3, and the assembly position is accurate and the connection is reliable.

[0047] See Figure 6 , Fig. 9 As shown, in some embodiments of the utility model, a screw hole 33 is provided on the hole wall of the sleeve hole 31, and a screw 5 is provided in the screw hole 33. After the screw 5 passes through the screw hole 33, it abuts against the outer wall of the hanging pipe 1 and presses the hanging pipe 1 tightly, so that the hanging pipe 1 and the hanging ball 3 are connected as a whole. Therefore, after the hanging pipe 1 is assembled on the hanging ball 3, it will not rotate or shake, so that when the ceiling fan is working, the ceiling fan can be ensured to rotate smoothly and supply air.

[0048] See also Figure 10-13 and Fig.15 , Fig.16 As shown, an embodiment of the second aspect of the utility model provides another ceiling fan, including a hanging tube 1, the hanging tube 1 is hollow to form a wire hole 11; a fan body 2, connected and fixed to the lower end of the hanging tube 1; a hanging ball 3, connected and fixed to the upper end of the hanging tube 1, the hanging ball 3 is provided with a sleeve hole 31, the upper end of the hanging tube 1 is inserted into the sleeve hole 31, and the upper end of the hanging tube 1 is formed with an outer flange 14, the maximum radial dimension of the outer flange 14 is greater than the minimum radial dimension of the sleeve hole 31, and the hanging tube 1 is suspended on the hanging ball 3 through the outer flange 14.

[0049] See Fig.16 As shown, in some embodiments, the outer flange 14 is vertically arranged with the hanging tube 1, and the outer flange 14 abuts against the upper surface of the hanging ball 3. In this embodiment, the outer flange 14 is formed by the upper end tube wall of the hanging tube 1 being extruded outward by a mold, and the outer flange 14 is used to abut against the upper surface of the hanging ball 3, so as to complete the hanging of the hanging tube 1 on the hanging ball 3; in other embodiments, see Figure 10-13 and Fig.15As shown, the outer flange 14 is arranged obliquely with the hanging tube 1, so that the outer wall of the upper end of the hanging tube 1 is larger at the top and smaller at the bottom to form an oblique outer wall 12, and the sleeve hole 31 has an oblique inner wall 34 that is larger at the top and smaller at the bottom, and the oblique outer wall 12 is adapted to the oblique inner wall 34, and the hanging tube 1 is suspended on the hanging ball 3 through the cooperation of the oblique outer wall 12 and the oblique inner wall 34. In this embodiment, by expanding the upper end of the hanging tube 1 to form a large end, the sleeve hole 31 forms an axial limit on the upper end of the hanging tube 1, thereby completing the suspension of the hanging tube 1 on the hanging ball 3. As a result, the cross pin used in the existing structure is abandoned, and the obstruction of the lead wire glue plug due to the existence of a single cross pin is completely avoided. Consumers can directly pass the lead wire and the glue plug on it through the wire hole 11 without disassembling the hanging ball and the hanging tube. According to the different specific shapes of the oblique inner wall 34 and the oblique outer wall 12, in this embodiment, the sleeve hole 31 forms a conical expansion at the position of the oblique inner wall 34 and the hanging pipe 1 forms a conical expansion at the position of the oblique outer wall 12. The hanging pipe 1 is suspended on the hanging ball 3 through the cooperation of the two conical expansions. The two conical expansions are tightly attached to each other in the circumferential direction, so that the connection between the hanging pipe 1 and the hanging ball 3 is reliable and does not shake. The conical expansion can be as follows Fig.11 The tapered bevel expansion shown may also be a tapered arc expansion (not shown in the drawing).

[0050] See Fig.10 , Fig.11 and Fig.13 , Fig.15 , Fig.16 As shown, in some embodiments of the utility model, a screw hole 33 is provided on the sleeve hole 31, and a screw 5 is provided in the screw hole 33. The screw 5 passes through the screw hole 33 and is connected with the hanging pipe 1, so that the hanging pipe 1 and the hanging ball 3 are connected as a whole. The hanging pipe 1 will not loosen relative to the hanging ball 3, which is convenient for subsequent assembly processes and also convenient for transportation.

[0051] In some embodiments, the screw 5 is tightened against the hanging pipe 1, specifically, it can be tightened against the inclined outer wall of the hanging pipe 1; in other embodiments, the hanging pipe 1 (specifically, it can be Fig.11 The sloping outer wall shown, or Fig.16 A hole 13 is provided on the outer wall of the hanging tube below the outer flange 14, and the screw 5 extends into the hole 13, so that the hanging tube 1 is limited by the screw 5, preventing the hanging tube 1 from shaking or rotating relative to the hanging ball 3, ensuring that the ceiling fan rotates smoothly and reliably.

[0052] See Figure 4-Figure 5As shown, the ceiling fan also includes a hanger 6, which is provided with a hanging hole 61, the hanging pipe 1 passes through the hanging hole 61, and the hanging ball 3 on the hanging pipe 1 is axially limited in the hanging hole 61. Specifically, the maximum radial dimension of the hanging ball 3 is larger than the inner diameter of the hanging hole 61, so that the hanging ball 3 will not fall out of the hanging hole 61 from top to bottom, and a limiting groove 35 is provided on the outer wall of the hanging ball 3. A limiting block 62 is provided in the hanging hole 61, and the limiting block 62 is inserted into the limiting groove 35 to limit the circumferential rotation of the hanging ball 3, thereby ensuring that the ceiling fan rotates smoothly and reliably.

[0053] From the above structural analysis, it can be known that the embodiments of the utility model are such that the pin shaft 4 is not inserted into the wire hole 11, or the pin shaft 4 is inserted into the wire hole 11 to form an insertion end, and the insertion ends of multiple pin shafts 4 are spaced apart; or an outer flange 14 is formed at the upper end of the hanging tube 1, and the maximum radial dimension of the outer flange 14 is larger than the minimum radial dimension of the sleeve hole 31. The hanging tube 1 is suspended on the hanging ball 3 by the outer flange 14, and the existing single cross pin structure is abandoned, so that there is no cross pin that passes horizontally through the wire hole of the hanging tube, thereby avoiding the existence of the cross pin to block the lead wire glue plug of the motor, etc. Therefore, when assembling, the consumer does not need to disassemble the connection between the hanging ball and the hanging tube, and can directly pass the glue plug of the motor lead wire, etc. through the wire hole of the hanging tube, thereby avoiding the secondary installation of the consumer, and will not cause the problem of abnormal noise or poor swing of the fan due to poor assembly, thereby ensuring the reliability of the ceiling fan after installation, with a simple structure and low implementation cost.
