ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a suspending structure of a ceiling fan. Two sides of the assembly hole of a suspender is formed with a cavity and an opening, and the engaging hole of the hanging bell is formed with long sides. Two ends of the long side are placed on the cavity and opening of the suspender. Thereby, as the swinging pipe set shifts toward said cavity, said swinging pipe is received within one end of said long side of the cavity. Therefore, a swing of large angle is generated, moreover, said swinging path of the swinging pipe set is confined by said buckle and said trench. Thus, the suspending structure according to the present invention can be suitable for a non-horizontal surface with a large angle shift safely.
BACKGROUND OF THE INVENTION
FIG. 1
shows a prior art suspending structure of a ceiling fan. The prior art suspending structure is formed by a suspender
10
, a swinging pipe set
11
and a hanging bell
12
. The suspender
10
is installed with an assembly hole
101
so that the hemisphere hanging head
111
can be installed within the assembly hole
101
and is swingable through a small swing angle. The bottom of the hanging bell
12
is formed with a round through hole
121
for being passed through by the swinging pipe
112
of the swinging pipe set
11
and then the hanging bell
12
is combined to the suspender
10
as a shielding body of the suspending structure of a ceiling fan.
In the prior art, the suspending structure of a ceiling fan, the swinging angle of the swinging pipe set in the suspender is confined by the assembly hole of the suspender, swinging pipe set, hanging bell and other factors about the safety and construction. Therefore, it can be installed to a general horizontal ceiling. For an installing surface with a large slope, not only it can not be installed thereto, but also is not safe.
SUMMARY OF THE INVENTION
Accordingly, the primary object of the present invention is to provide a suspending structure of a ceiling fan, wherein, two sides of the assembly hole of a suspender is formed with a cavity and a opening, and the engaging hole of the hanging bell is formed with long sides. Two ends of each long side are placed on the cavity and opening of the suspender. Thereby, as the swinging pipe set shifts toward said cavity, said swinging pipe is received within one end of said long side of the cavity. Therefore, a swing of large angle is generated, moreover, said swinging path of the swinging pipe set is confined by said buckle and said trench. Thus, the suspending structure according to the present invention can be suitable for a non-horizontal surface with a large angle shift safely.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
