Clipping piece structure for goggles

Abstract

A clipping piece structure for goggles solves the existing risks to users of prior art. A clipping piece connects an elastic strap to the protective goggles. The protective goggles have a lens and a frame. The lens and the frame have engaging holes formed on two sides, respectively. The clipping piece has a main body and a blocking piece. The main body has a strap connecting part connected with the elastic strap and hooking arms extending from one side of the strap connecting part and defining a receiving space between the hooking arms. The hooking arms are wedged into the engaging holes for retaining the lens on the frame. The blocking piece is movably disposed in the receiving space between the hooking arms, and the blocking piece props against the inside walls of the hooking arms.

1 . A clipping piece structure for goggles, connecting an elastic strap, a lens, and a frame, said lens and said frame respectively formed with a pair of engaging holes at two sides thereof, comprising:
 a main body, with a strap connecting part for connecting said elastic strap and a pair of hooking arms disposed at one side of said strap connecting part and defining a receiving space between said pair of hooking arms, said pair of hooking arms wedging into said engaging holes for retaining said lens related to said frame; and   a blocking piece, movably disposed in said receiving space between said pair of hooking arms, said blocking piece propping against an inside of said pair of hooking arms.   
   
   
       2 . The clipping piece structure for goggles as claimed in  claim 1 , further comprising an extending portion located between said strap connecting part and said pair of hooking arms, wherein said extending portion has a bendable folding portion connecting to said strap connecting part. 
   
   
       3 . The clipping piece structure for goggles as claimed in  claim 1 , wherein said pair of hooking arms are respectively formed with an anti-sliding portion at an outside surface thereof. 
   
   
       4 . The clipping piece structure for goggles as claimed in  claim 1 , wherein said receiving space is composed of a curved space extending from said extending portion to said pair of hooking arms, and a trapezoid space communicating with said curved space. 
   
   
       5 . The clipping piece structure for goggles as claimed in  claim 4 , wherein said blocking piece has a shape corresponding to that of said receiving space and has a curved portion and a trapezoid portion connected with said curved portion, and said blocking piece props against said extending portion and said frame. 
   
   
       6 . The clipping piece structure for goggles as claimed in  claim 1 , wherein said blocking piece has a pair of protruding blocks protruding from one side thereof and facing towards said protective goggles, and said protruding blocks protrude in a direction substantially parallel to said pair of hooking arms and are wedged into said pair of engaging holes of said frame. 
   
   
       7 . The clipping piece structure for goggles as claimed in  claim 1 , further comprising a sub-folding portion connecting said blocking piece to said extending portion. 
   
   
       8 . The clipping piece structure for goggles as claimed in  claim 1 , wherein a pair of pivotal shafts protrudes from said blocking piece, said pivotal shafts are perpendicular to said pair of hooking arms, and said pair of hooking arms are respectively formed with a pivotal hole for receiving said pair of pivotal shafts. 
   
   
       9 . The clipping piece structure for goggles as claimed in  claim 1 , wherein a pair of pivotal shafts and a pair of protruding blocks protrude from said blocking piece, said protruding blocks are respectively wedged into said pair of engaging holes of said frame, said pair of hooking arms are respectively formed with a pivotal slot, and said pair of pivotal shafts are slidably disposed in said pair of pivotal slots along a direction of said hooking arm. 
   
   
       10 . The clipping piece structure for goggles as claimed in  claim 1 , wherein said blocking piece is horseshoe-shaped. 
   
   
       11 . The clipping piece structure for goggles as claimed in  claim 1 , wherein said blocking piece has a covering board and a pair of side boards oppositely connected with two sides of said covering board, each said side board has a pair of protruding bars protruding from an inner surface thereof, and said protruding bars are wedged into said corresponding engaging holes of said lens and said frame. 
   
   
       12 . The clipping piece structure for goggles as claimed in  claim 1 , wherein each said hooking arm has a guiding rail protruding toward said receiving space, said blocking piece has a holding portion and a pair of restraining arms extending from two ends of said holding portion, and said pair of restraining arms are respectively formed with a guiding groove at a top surface thereof corresponding to said guiding rails. 
   
   
       13 . The clipping piece structure for goggles as claimed in  claim 12 , wherein said guiding rails respectively have at least one positioning protrusion, and said restraining arms are respectively formed with at least one position notch corresponding to said positioning protrusion.
