Description

Trim ring on ceiling fan bracket housing

(1) Technical field

The utility model relates to a fan, in particular to a decorative ring on the outer cover of a ceiling fan bracket.

(2) Background technology

Ceiling fan brackets are typically fitted with a cover to conceal and contain the bracket and exposed wires. Since the outer cover is generally fixed on the bracket with screws, there are exposed screw heads on the outer cover, so that the overall appearance of the ceiling fan is not very harmonious and beautiful.

For this reason, U.S. Patent No. 6,010,110 discloses a decorative ring for a ceiling fan bracket cover. There are multiple pairs of "J"-shaped grooves arranged side by side corresponding to the positions of the fixing screw holes on the bracket cover, one end of the grooves is closed, and the other end is a receiving port. When installing, align each receiving port with the exposed screw head of the bracket cover and push up, so that the screw head enters the groove, and then push the decorative ring laterally so that the screw head finally reaches the closure of the "J"-shaped groove end. When the bezel is pushed onto the upper edge of the bracket cover, it fits snugly against the upper edge. Obviously, it is more difficult to make the decorative ring with a smooth outer peripheral surface laterally displace at this time, because at this time its inner peripheral surface is closely attached to the outer cover and there is a certain resistance.

(5) specific implementation

As shown in FIGS. 1 and 2 , the decorative ring 1 of the present invention can be installed on the upper peripheral surface 210 of the ceiling fan housing 2 through the fixing parts thereon to cover the exposed screw heads 220 a and 220 b.

As shown in FIGS. 2 and 3 , the decorative ring 1 includes an outer peripheral surface 110 and an inner peripheral surface 120 and is in the shape of an inverted truncated cone. A pair of fixing parts 130 corresponding to the exposed screw heads 220a and 220b on the outer surface 210 of the bracket cover 2 and detachably combined are provided on the inner ring circumferential surface 120 . Each of the fixing members 130 includes a pair of elastic holders 131 and 132 arranged side by side opposite each other. One end of the holders 131 and 132 is a free end 131a and 132a. 131b and 132b, and the other end 131c and 132c are integrated with the ring body 1 . The free ends 131a and 132a are substantially at right angles to the other laterally disposed ends 131c and 132c. The distance between the free ends is slightly larger than the width between the two outer ends of a pair of exposed screw heads 220a and 220b on the bracket cover 2, and the protrusions 131b and 132b of the free ends are wider than the two outer ends of the exposed screw heads 220a and 220b. The width between them is slightly smaller. The protrusions 131b and 132b are substantially in a "v" shape, that is to say, the distal ends of the pair of opposite protrusions 131b and 132b are inclined inwardly respectively, so that the screw heads 220a and 220b can be easily Enter between the elastic holders 131 and 132 to hold the bezel 1 on the cover 2 .

The outer sides of the pair of elastic holders 131 and 132 are at an appropriate distance from the protrusions 131b and 132b, and each has a stopper 140a and 140b. The stoppers 140a and 140b are substantially on the same inclined plane as the distal ends of the protrusions 131b and 132b. This can prevent one of the screw heads 220a and 220b from falling into the outside of one of the elastic holders 131 and 132 during installation, and the screw head can pass through the protrusions 131b and 132b along the inclined surface. into between holders 131 and 132. When the screw heads 220a and 220b pass through the protrusions 131b and 132b, the protrusions deviate to the two outer sides due to the force and are blocked by the stoppers 140a and 140b, and at this time, the protrusions 131b and 132b The distance between them is sufficient to allow the screw heads 220a and 220b to pass through. The protrusions prevent the holders 131 and 132 from breaking due to excessive outward movement.

A plurality of wedge-shaped positioning blocks 150 are arranged on the circumferential surface 120 of the inner ring and extend along the central axis. Since the decorative ring 1 is in the shape of a truncated cone, the upper side 210 of the ceiling fan cover 2 is in the shape of a cylinder. After the decorative ring 1 is held on the outer cover 2, there will be many gaps on the surface of the inner ring of the decorative ring 1 other than the fixing part 130. Because the decorative ring is generally made of plastic material, it will be deformed due to insufficient strength. The wedge-shaped positioning blocks 150 on the inner circumferential surface 120 of the decorative ring are evenly supported on the upper edge of the outer cover 2 at different angles, which not only play a positioning role but also make the decorative ring 1 more stable and not deformed.

A boss 160 extending radially inward from the peripheral edge is also provided on the peripheral bottom edge of the inner ring. The boss 160 can close the bottom edge of the upper circumference 210 of the outer cover 2 after the bezel 1 is held on the outer cover 2 . The boss 160 can not only beautify the appearance, but also make the shape of the decorative ring 1 more stable.

Figure 3 shows the installation steps of the decorative ring of the present utility model. First, align the elastic retainer 130 on the inner peripheral surface 120 of the bezel roughly with the exposed screw heads 220a and 220b on the bracket cover 2; The decorative ring can be smoothly pushed onto the upper peripheral surface 210 of the ceiling fan housing 2, so it is easy to align the retainers 131 and 132 with the screw heads 220a and 220b, and because of the pair of stoppers 140a and 220b on the inner peripheral surface 120 140b and the distal ends 131b and 132b of a pair of free ends 131a and 132a of the corresponding holders 131 and 132 are on the same inclined plane. Move the bezel so that it slides toward the pair of holders along the inclined surface, so that the screw head can be pushed away from the pair of protrusions 131a and 132a of the holder and enter the middle of the holders 131 and 132 as long as a little force is applied. , and then the protrusion is automatically reset so that the screw head is held between the free ends 131a and 132a and the fixed ends 131c and 132c of the pair of holders. Because the decorative ring is generally made of plastic material, so the weight is lighter, and the protrusions can play a role in stopping the retreat and the plurality of wedge-shaped positioning blocks 150 on the inner peripheral surface of the decorative ring play a certain supporting role, so that the decorative ring can Secures to the housing of the ceiling fan bracket. When the decorative ring needs to be disassembled, as long as the decorative ring is held by hand and pulled down with a little force, the decorative ring can be removed. ″ shape, when a downward pulling force is applied to the decorative ring, the protrusions will be pushed outward by the screw head along the downward slope of the “V” shape, so that the decorative ring can be easily removed.
