TikZ - Clipping the squares ring

Question

I tried to create the following picture but I have not succeeded.

I just made it like this.

\documentclass[border=10pt]{standalone}
\usepackage[x11names]{xcolor}
\usepackage{tikz}
\usetikzlibrary{calc,intersections,patterns,knots}
\usepackage{adjustbox}

\begin{document} 
\pagecolor{LightSkyBlue1!30}

\begin{tikzpicture}[line join=round,line cap=rounded]
\coordinate[label=left:] (A) at (0,2);
\coordinate[label=right:] (B) at (0,0);
\coordinate[label=left:] (O) at (0,1);
\fill[Cyan4] (-.175,-.175) rectangle (9.175,2.175);
\begin{knot}[clip width=2,clip radius=0cm]
    \strand[white,line width=0.1cm,double=Cyan4,double distance=.15cm,even odd rule] (-.175,-.175)--(1,1)--(-.175,2.175)
    (1,0)--(2,1)--(1,2)--(0,1)--cycle
    (2,0)--(3,1)--(2,2)--(1,1)--cycle
    (3,0)--(4,1)--(3,2)--(2,1)--cycle
    (4,0)--(5,1)--(4,2)--(3,1)--cycle
    (5,0)--(6,1)--(5,2)--(4,1)--cycle
    (6,0)--(7,1)--(6,2)--(5,1)--cycle
    (7,0)--(8,1)--(7,2)--(6,1)--cycle
    (8,0)--(9,1)--(8,2)--(7,1)--cycle
    (9.175,2.175)--(8,1)--(9.175,-.175);
\end{knot}
\draw[ultra thick,Cyan4] (-.2,-.2) rectangle (9.2,2.2);
\begin{scope}[even odd rule]
\path[pattern=crosshatch dots,pattern color=Cyan4] 
(-.175,-.175) rectangle (9.175,2.175)
(-.5,-.5) rectangle (9.5,2.5) ;
\end{scope}

\end{tikzpicture}

\end{document}

How to create the original image?

Answer 1

Very quick eyeballing solution

\documentclass[tikz]{standalone}
\usetikzlibrary{shapes.geometric}
\begin{document}
\begin{tikzpicture}
\clip[postaction=fill] (0,-2) rectangle (8,2);
\foreach\x in{1.5,0,-1.5}{\foreach\y in{-4,...,4}{\draw[white,thick](0,\x+ 0.1*\y)--++(8,0);}}
\foreach \x in {0,...,8}{
  \node[diamond,minimum size=1.5cm] (n-\x) at (\x, 0) {};
  \draw[draw=white,double=black, double distance between line centers=2mm,line width=1mm] 
  ([shift={(-135:3mm)}]n-\x.east)--(n-\x.east)--(n-\x.north)--([shift={(45:5mm)}]n-\x.west)
  ([shift={(-135:5mm)}]n-\x.east)--(n-\x.south)--(n-\x.west)--([shift={(45:2.2mm)}]n-\x.west);
  \draw[thick] ([yshift=0.21cm]n-\x.north) -- ([yshift=-0.21cm]n-\x.south);
}
\draw[thick](0,0)--++(8,0);
\end{tikzpicture}
\end{document}

Answer 2

Maybe more complete option but with some tricky elements, and some patterns issues like diferent rendering in some pdf viewers..., but you can modify to obtain some good result in your document.

RESULT: TikzEdt viewer

RESULT: Firefox viewer ...{tikzpicture}[scale=1.5]
