Detailed Description
Example 1
Referring to fig. 1-4, a folding wind brace is characterized by comprising a first brace rod 1 and a second brace rod 2; one end of the first stay bar 1 is hinged on a window frame section bar 3, one end of the second stay bar 2 is hinged on a window sash section bar 4, the first stay bar 1 is connected with the second stay bar 2 through a rivet 5, and the rivet 5 is fixed on the first stay bar 1;
referring to fig. 5, the joint of the first stay bar 1 and the second stay bar 2 is a circular end, the diameter of the circle is larger than the width of the stay bar body, and a rivet hole 1.1 is formed in the circular end;
referring to fig. 6, the joint of the second stay bar 2 and the first stay bar 1 is a circular end, the diameter of the circle is larger than the width of the stay bar body, and the circular end is provided with a first waist-shaped through hole 2.1, a second waist-shaped through hole 2.2 and an arc-shaped through hole 2.3; one end of the arc-shaped through hole 2.3 is communicated with the second waist-shaped through hole 2.2.
Steps are arranged in the first waist-shaped through hole 2.1, the second waist-shaped through hole 2.2 and the arc-shaped through hole 2.3.
Referring to fig. 7, the rivet is divided into a first rivet 5.1 and a second rivet 5.2, wherein the first rivet 5.1 is located in the first kidney-shaped through hole 2.1; the second rivet 5.2 is arranged in the arc-shaped through hole 2.3, the first rivet 5.1 and the second rivet 5.2 are respectively three parts, the first part 51 is connected to the first support rod, the second part 52 is arranged in the first waist-shaped through hole 2.1, the second waist-shaped through hole 2.2 and the arc-shaped through hole 2.3, and the third part 53 is arranged on a step in the first waist-shaped through hole 2.1, the second waist-shaped through hole 2.2 and the arc-shaped through hole 2.3.
