Quick ceiling fan mounting bracket with safety protection structure

#The present invention relates to a ceiling fan mounting bracket, and more particularly to a quick ceiling fan mounting bracket with a safety protection structure.

#As shown in FIG. 1, a conventional ceiling fan mounting bracket 1 is connected to a junction box 2. The junction box 2 is installed to the ceiling. The ceiling fan mounting bracket 1 has a bracket body 3. The bracket body 3 is provided with two slots 4. One end of each slot 4 is formed with a position hole 5. In the ceiling fan mounting bracket 1, two screws 6 are respectively inserted through the corresponding position holes 5, and the screws 6 are moved to the corresponding slots 4. By positioning the screws 6 in the slots 4, the ceiling fan mounting bracket 1 is fixed to the junction box 2. Finally, a ceiling fan motor unit is installed for the ceiling fan to operate normally.

#However, the screw 6 of the ceiling fan mounting bracket 1 is not blocked by a stopper. If the ceiling fan runs for a long time and vibrates, it is easy to cause the screw 6 to loosen or have a displacement. As a result, the screw 6 may move from the slot 4 to the position hole 5 or fall off from the position hole 5, causing the ceiling fan to fall. Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems.

#Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

#As shown in FIGS. 2-7, the present invention discloses a quick ceiling fan mounting bracket 100 with a safety protection structure, comprising a bracket 10. Referring to FIGS. 2-3, a junction box 20 is provided on the top of the bracket 10. The junction box 20 has two locking holes 21. A locking member 22 is locked to each of the locking holes 21 of the junction box 20 in a bottom-up direction. The locking member 22 is a screw. The locking member 22 has a head 221 and a locking member body 222. The radius of the head 221 of the locking member 22 is greater than the radius of the locking member body 222. Two sides of the bracket 10 are provided with a plurality of fasteners 23 for fastening a casing. A ceiling fan motor unit 30 is fixedly connected to the underside of the bracket 10. The ceiling fan motor unit 30 is composed of a motor 31 and a connecting support 32.

#Please refer to FIGS. 4-7. The bracket 10 is provided with two guide rails 40. The guide rails 40 each has a positioning hole 41 in the bracket 10. The positioning holes 41 of the guide rails 40 correspond in position to the locking holes 21 of the junction boxes 20, respectively. The diameter of the positioning hole 41 is greater than the diameter of the head 221 of the locking member 22. The positioning hole 41 extends toward a guide direction 42a to form a guide hole 42. The positioning hole 41 is provided with a guide portion 43 at a position adjacent to the guide hole 42. The guide portion 43 is tapered inward toward the guide hole 42 to guide the displacement of the locking member body 222 of the locking member 22. The width of the guide hole 42 is greater than the diameter of the locking member body 222. The width of the guide hole 42 is less than the diameter of the head 221 of the locking member 22. Each guide hole 42 defines an outer guide hole section 421 adjacent to the positioning hole 41 and an inner guide hole section 422 far away from the positioning hole 41, so that the spaces, including two sides of the positioning hole 41 of each guide rail 40, the positioning hole 41, the outer guide hole section 421 and two sides of the outer guide hole section 421, are connected to form a guide path 44 for guiding the displacement of the locking member 22. One of the guide rails 40 is defined as a first guide rail 401. The positioning hole 41, the outer guide hole section 421 and the guide path 44 of the first guide rail 401 are defined as a first positioning hole 401a, a first outer guide hole section 401b, and a first guide path 401c. The other guide rail 40 is defined as a second guide rail 402. The first guide hole 401b of the first guide rail 401 and the second guide rail 402 are arranged on the same plane. The first positioning hole 401a of the first guide rail 401 is arranged downward and obliquely from the first guide hole 401b toward the first positioning hole 401a, so that a reserve space is formed above the first positioning hole 401a.
