Structure of ceiling fan blades their frames

Abstract

A structure of blade and blade frame for a ceiling fan is disclosed. The inserting parts of a blade frame go through the through holes on a blade. Each inserting part has a stopping part exposed from the blade. An elastic positioning element connects several limiting parts using linear linking parts. The limiting parts urge against the stopping parts in opposite directions, providing constraints between the stopping parts and the blade and, thereby, combining the blade and the blade frame.

1 . A structure of blade and blade frame for a ceiling fan, comprising:
 a blade, whose one end has at least two through holes;   a blade frame, which has an inserting part for each of the through holes on the blade, each of the inserting parts having a stopping part that prevents the blade frame from leaving the blade on the exposed end from the blade; and   an elastic positioning element restoring its position after pressure release, which has a plurality of limiting parts each of which urges against the stopping parts after the inserting parts go through the corresponding through holes, blocking the stopping parts by sticking between the stopping parts and the blade.   
   
   
       2 . The structure of blade and blade frame for a ceiling fan as in  claim 1 , wherein the inserting parts are independent elements fixed on the blade frame. 
   
   
       3 . The structure of blade and blade frame for a ceiling fan as in  claim 1 , wherein the blade has a covering element to cover the part of the inserting part exposed from the blade and the positioning element. 
   
   
       4 . The structure of blade and blade frame for a ceiling fan as in  claim 1 , wherein the positioning element has a hook-shaped limiting part on either end thereof and another arc-shaped limiting element between the two hook-shaped limiting parts connected using a linear structure. 
   
   
       5 . The structure of blade and blade frame for a ceiling fan as in  claim 1 , wherein the positioning element has a linear linking part between each two consecutive limiting parts. 
   
   
       6 . The structure of blade and blade frame for a ceiling fan as in  claim 1 , wherein each of the stopping parts includes a first stopping part for the limiting part to block after it restores its position and a second stopping part blocking the limiting part after the inserting part goes through the through hole.
