DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] See also Figure 1 and Figure 2 As shown, the present invention discloses a fan light 100, which is used to be installed on a mounting surface (not shown), and has a lighting effect while ventilating and dissipating heat. The fan light 100 includes a suspension rod 400, a fan assembly 500, a lighting assembly 600, a suspension rod connection structure 200 and a ceiling box 300. One end of the suspension rod connection structure 200 is connected to the fan assembly 500 and the lighting assembly 600 through the suspension rod 400, and the other end is connected to the mounting surface to install the fan light 100 on the mounting surface. The ceiling box 300 is assembled with the suspension rod connection structure 200 to cover the suspension rod connection structure 200 to prevent the suspension rod connection structure 200 from being exposed and affecting the overall beauty of the fan light 100.

[0025] Specifically, the suspension rod connection structure 200 includes a bracket 2 and a movable part 1, the movable part 1 is connected to the suspension rod 400, and at least part of the movable part 1 is in contact with the bracket 2 to achieve a detachable connection between the suspension rod 400 and the bracket 2, and the bracket 2 is respectively connected to the mounting surface and the ceiling box 300 to mount the fan light 100 on the mounting surface and cover the suspension rod connection structure 200.

[0026] The specific structures of the fan assembly 500 and the lighting assembly 600, and the connection structure between the fan assembly 500, the lighting assembly 600 and the suspension rod 400 can be designed according to the prior art and will not be described in detail herein.

[0027] See also Figures 2 to 5 As shown, the movable part 1 includes a contact surface 16 which is at least partially curved, and the bracket 2 includes a bottom plate 21 and an abutment member 211 which is integrally formed with the bottom plate 21 and can abut against the movable part 1. The abutment member 211 is provided with an abutment surface 214 corresponding to the contact surface 16. When the movable part 1 is connected to the bracket 2, the contact surface 16 fits with the abutment surface 214, and the contact surface 16 can slide relative to the abutment surface 214 to realize the movable connection between the movable part 1 and the bracket 2. Preferably, the movable part 1 is hemispherical, and the contact surface 16 is a spherical surface, so that the movable part 1 can rotate in multiple directions relative to the abutment member 211.

[0028] Specifically, the bottom plate 21 is provided with a through hole 212, and the abutment 211 is arranged in a strip shape and surrounds at least part of the through hole 212. The abutment 211 is arranged in a contracted shape, and the diameter of the side away from the bottom plate 21 is larger than the diameter of the through hole 212. That is to say, the abutment 211 is integrally formed with the bottom plate 21 and is arranged at a certain angle to the bottom plate 21, preferably with a "larger on top and smaller on the bottom" structure, so that the abutment surface 214 can fully fit with the contact surface 16.

[0029] During connection, at least part of the movable part 1 can pass through the through hole 212, so that the contact surface 16 fits with the abutment surface 214, wherein the diameter of the through hole 212 is smaller than the diameter of the movable part 1, so that the movable part 1 cannot completely pass through the through hole 212, so as to realize the connection between the movable part 1 and the bracket 2. The abutment surface 214 and / or the contact surface 16 are rough surfaces to increase the friction between the movable part 1 and the bracket 2. When the fan rotates, the movable part 1 is prevented from rotating relative to the bracket 2, so as to improve the connection stability between the movable part 1 and the bracket 2, and at the same time, some vibrations of the fan body can be eliminated. Preferably, the rough surface can be a frosted surface, or a frosted line with a pattern can be set on the surface of the abutment 211 and / or the movable part 1, as long as the effect of increasing friction can be achieved, there is no limitation here.

[0030] A positioning hole 215 is provided on the abutting member 211, and a positioning member 15 matching the positioning hole 215 is provided on the movable member 1. The positioning member 15 is received in the positioning hole 215 to limit the circumferential rotation of the movable member 1 relative to the hanger 2. The positioning member 15 is block-shaped and arranged on the contact surface 16 of the movable member 1, and protrudes outward from the contact surface 16. The size of the positioning hole 215 is larger than that of the positioning member 15, so that the positioning member 15 can move in the positioning hole 215. Of course, in other embodiments, the size of the positioning member 15 and the positioning hole 215 can be the same to fix the movable member 1 and the hanger 2.

[0031] The movable part 1 is fixedly connected to the suspension rod 400, and a notch 213 connected to the through hole 212 is also provided on the bottom plate 21. The suspension rod 400 passes through the notch 213 to enter the through hole 212, and enables the movable part 1 to abut against the abutment 211. Specifically, the size of the notch 213 matches the suspension rod 400, so that the suspension rod 400 can move freely in the notch 213, and the size of the notch 213 is smaller than the diameter of the through hole 212. When the movable part 1 is in contact with the abutment 211, the movable part 1 cannot slide out through the notch 213.

[0032] Among them, the suspension rod connection structure 200 also includes a limiting member (not shown in the figure), the movable part 1 is provided with a through hole 11 for the suspension rod 400 to pass through and a limiting hole 12 connected to the through hole 11, and the suspension rod 400 is provided with a connecting hole 4 corresponding to the limiting hole 12. The limiting member passes through the limiting hole 12 and the connecting hole 4 to connect the movable part 1 and the suspension rod 400. Specifically, there are two limiting holes 12, one large and one small, and the two limiting holes 12 are arranged relatively on the same straight line. The smaller limiting hole 12 has the same size as the connecting hole 4. With this arrangement, after the limiting member passes through the smaller limiting hole 12, it can easily and quickly pass through the larger limiting hole 12, which saves installation time on the one hand and reduces the processing accuracy of the two limiting holes 12 on the other hand, further reducing the production cost.

[0033] The movable part 1 further includes a fixing part (not shown) and a fixing hole 13 connected to the through hole 11, wherein the fixing hole 13 is staggered with the limiting hole 12. When the limiting part connects the suspension rod 400 and the movable part 1, the fixing part passes through the fixing hole 13 and abuts against the suspension rod 400 to fix the suspension rod 400 and the movable part 1. Preferably, two adjacent fixing holes 13 are provided, and the fixing part is a fastening screw.

[0034] In this embodiment, the movable part 1 also includes a groove 14 corresponding to the fixing hole 13. The groove 14 extends from the contact surface 16 toward the through hole 11 and connects the fixing hole 13 with the groove 14, so that the fixing part can pass through the groove 14 and the fixing hole 13 and protrude into the through hole 11 to abut against the suspension rod 400. That is to say, one end of the fixing part abuts against the suspension rod 400, and the other end is accommodated in the groove 14 to prevent the fixing part from protruding from the contact surface 16. Of course, in other embodiments, the groove 14 may not be provided. In this case, the fixing hole 13 directly passes through the contact surface 16 to the through hole 11.

[0035] The hanger 2 includes a bottom plate 21, a side plate 22, a first connection portion 23 and a second connection portion 24. The side plate 22 is provided with two and is respectively arranged on two opposite sides of the bottom plate 21. The first connection portion 23 and the second connection portion 24 are respectively connected to the two side plates 22 and both extend outward from the side plates 22. Preferably, the first connection portion 23 and the second connection portion 24 are both arranged parallel to the bottom plate 21.

[0036] The side panels 22 are provided with reinforcing ribs 221 perpendicular to the edges of the bottom panel 21 to increase the strength of the side panels 22 . Preferably, each side panel 22 is provided with two reinforcing ribs 221 .

[0037] The difference between the first connection part 23 and the second connection part 24 is that the first connection part 23 includes a first connection arm 231, the second connection part 24 includes a second connection arm 241, and the first connection arm 231 and the second connection arm 241 are arranged opposite to each other and connected to each other, so as to increase the connection strength of the hanger 2. Preferably, two first connection arms 231 and two second connection arms 241 are provided, and are respectively arranged at the two ends of the first connection part 23 and the second connection part 24, and the first connection arm 231 and the second connection arm 241 match each other at the connection and are fixedly connected by welding, riveting, screw connection, etc. In addition, the structures of the first connection part 23 and the second connection part 24 are the same, and the following description takes the first connection part 23 as an example for description.

[0038] The first connecting portion 23 is provided with a mounting hole 232 and a mounting member 233 matching the mounting hole 232. The mounting member 233 passes through the mounting hole 232 and is connected to the mounting surface to fix the hanger 2 on the mounting surface to fix the hanger connecting structure 200 on the mounting surface. Preferably, the mounting member 233 is an expansion screw to achieve convenient installation of the hanger connecting structure 200 and the mounting surface.

[0039] In this embodiment, shock-absorbing plates 235 are provided around the mounting hole 232. When the bracket 2 is installed on the mounting surface, the shock-absorbing plate 235 is arranged between the bracket 2 and the mounting surface to reduce the vibration generated when the fan rotates, avoid the loosening of the mounting member 233, and extend the service life of the suspension rod connection structure 200. Preferably, the shock-absorbing plate 235 is a foam pad.

[0040] The ceiling box 300 is provided with a receiving cavity for receiving the suspension rod connection structure 200. Specifically, the ceiling box 300 is sleeved on the suspension rod 400 and receives the suspension rod connection structure 200 in the receiving cavity to cover the suspension rod connection structure 200 and beautify the appearance of the fan light 100. A protrusion 3 is provided on the inner side wall of the receiving cavity of the ceiling box 300. The suspension rod connection structure 200 includes a clamping piece 234 corresponding to the protrusion 3. The protrusion 3 abuts against the clamping piece 234 to fix the suspension rod connection structure 200 and the ceiling box 300. Specifically, the clamping piece 234 is provided on the first connection part 23, and the plane where the clamping piece 234 is located is lower than the plane where the first connection part 23 is located, so that the protrusion 3 can smoothly abut against the clamping piece 234 to achieve fixed connection between the ceiling box 300 and the suspension rod connection structure 200.

[0041] The clamping member 234 is provided with a guide bar 236 and a clamping groove 237. A clamping block (not shown) is provided on one side of the protrusion 3 close to the clamping member 234. When connected, the clamping block is accommodated in the clamping groove 237 to achieve the connection between the ceiling box 300 and the first connecting portion 23. The guide bar 236 is arranged obliquely relative to the clamping member 234 to guide the clamping block to abut against the clamping member 234 to achieve the installation of the ceiling box 300 and the suspension rod connection structure 200. The clamping groove 237 is arranged in the middle position of the clamping member 234, and the clamping groove 237 matches the protrusion 3 to achieve the matching connection between the clamping member 234 and the clamping block. Preferably, the two sides of the protrusion 3 are arranged obliquely to facilitate the installation and removal of the ceiling box 300.

[0042] In general, when assembling the fan lamp 100, first, use the mounting piece 233 to pass through the mounting hole 232 to fix the bracket 2 on the mounting surface, then, connect the fan assembly 500 and the lighting assembly 600 to one end of the suspension rod 400, insert the ceiling box 300 into the other end of the suspension rod 400, and then fix the movable part 1 to the other end of the suspension rod 400 through the limiter and the fixing piece, and then, pass the suspension rod 400 into the through hole 212 of the bracket 2 through the notch 213, so that the movable part 1 abuts against the abutment piece 211 to realize the movable connection between the suspension rod 400 and the suspension rod connecting structure 200, and finally, lift the ceiling box 300 upward and rotate it left and right, so that the snap-in block abuts against the snap-in piece 234, and the protrusion 3 is accommodated in the snap-in groove 237, so as to realize the assembly of the ceiling box 300 and the suspension rod connecting structure 200.

[0043] In summary, the fan light 100 of the present invention eliminates the vibration generated when the fan assembly 500 rotates by providing an abutting surface 214 on the bracket 2 that can fit with the contact surface 16 of the movable part 1, thereby reducing wear and improving the service life of the fan light 100; the abutting surface 214 on the abutting part 211 fits with the contact surface 16 on the movable part 1, thereby increasing the contact area between the bracket 2 and the movable part 1, reducing the wear between the movable part 1 and the bracket 2, and improving the user experience; A rough surface is provided on 14 and / or the contact surface 16 to increase the friction between the movable part 1 and the bracket 2 to prevent the movable part 1 from sliding freely relative to the bracket 2; a positioning member 15 is provided on the movable part 1, and a positioning opening 215 matching the positioning member 15 is provided on the abutment member 211 to limit the rotation angle of the movable part 1 relative to the bracket 2; the bracket 2 and the ceiling box 300 are connected to each other through the clamping block and the clamping member 234 to cover the suspension rod connection structure 200, thereby realizing the beautification of the fan lamp 100.
