Abstract

A ceiling fan positioning structure includes a fixing frame, a decoration casing, a plurality of retaining mechanisms and a plurality of convex posts. The convex posts are disposed on the fixing frame and the retaining mechanisms are fixed on the decoration casing; alternatively, the convex posts are disposed on the decoration casing and the retaining mechanisms are fixed on the fixing frame. In addition, each retaining mechanism has a base seat and an elastic plate, the base seat has a channel and a chamber for receiving the elastic plate. Therefore, each convex post is received in the channel of each base seat. When the decoration casing is rotated, each convex post is moved into each chamber. When the decoration casing is rotated to a predetermined position, the position of each convex post is limited in each chamber by the elastic force of each elastic plate.

Claims

1. A ceiling fan positioning structure for shielding a hanging portion of a ceiling fan, comprising:

a fixing frame, wherein the hanging portion is fixed by the fixing frame, and the fixing frame has a plurality of convex posts disposed on an external portion thereof;

a decoration casing for shielding the fixing frame and the hanging portion; and

a plurality of retaining mechanisms fixed on an inner wall of the decoration casing, wherein each retaining mechanism has a base seat and an elastic plate, the base seat has a channel and a chamber for receiving the elastic plate, and the elastic plate has a pressing arm bent on an end thereof;

whereby the decoration casing covers the fixing frame, each convex post is received in the channel of each base seat;

when the decoration casing is rotated, each convex post is moved towards each elastic plate and into each chamber, and each convex post touches each elastic plate in order to change the shape of each elastic plate;

when each convex post is moved to touch each pressing arm and an inner wall of the chamber, the position of each convex post is limited between each pressing arm and the inner wall of each chamber by the elastic force of each pressing arm.

2. The ceiling fan positioning structure according to claim 1, wherein the fixing frame has a top frame and a bottom frame connected with the top frame, the convex posts are disposed on an external portion of the top frame, and the hanging portion of the ceiling fan is fixed by the bottom frame.

3. The ceiling fan positioning structure according to claim 1, wherein each elastic plate has a fixing arm fixing in the chamber of the base seat and an elastic arm bent and extended from one side of the fixing arm, and the pressing arm is bent and extended from an end of the elastic arm.

4. The ceiling fan positioning structure according to claim 3, wherein each convex post touches each elastic arm of each elastic plate to make the elastic arm generate a predetermined elastic force.

5. A ceiling fan positioning structure for shielding a motor of a ceiling fan, comprising:

a fixing frame fixed by a joint shaft of the ceiling fan;

a decoration casing for shielding the motor, wherein the decoration casing has a plurality of convex posts projected inwards and disposed on an external portion thereof; and

a plurality of retaining mechanisms fixed on an external portion of the fixing frame, wherein each retaining mechanism has a base seat and an elastic plate, the base seat has a channel and a chamber for receiving the elastic plate, and the elastic plate has a pressing arm bent on an end thereof;

whereby the decoration casing covers the fixing frame, each convex post is received in the channel of each base seat;

when the decoration casing is rotated, each convex post is moved towards each elastic plate and into each chamber, and each convex post touches each elastic plate in order to change the shape of each elastic plate;

when each convex post is moved to touch each pressing arm and an inner wall of the chamber, the position of each convex post is limited between each pressing arm and the inner wall of each chamber by the elastic force of each pressing arm.

6. The ceiling fan positioning structure according to claim 5, wherein each elastic plate has a fixing arm fixing in the chamber of the base seat and an elastic arm bent and extended from one side of the fixing arm, and the pressing arm is bent and extended from an end of the elastic arm.

7. The ceiling fan positioning structure according to claim 6, wherein each convex post touches each elastic arm of each elastic plate to make the elastic arm generate a predetermined elastic force.
