the two or more hard supporting plates and the flexible protective layer are connected to form a whole; gaps are formed between every two adjacent hard supporting plates and are used as folding seams, so that the protective shield can be folded along the folding seams and stored;
the hard supporting plate is arranged on the surface of the flexible protective layer according to the following rule:
seven hard support plates are used as a folding unit; the protection shield comprises more than two folding units; the more than two folding units symmetrically extend along the length direction to form the protection shield;
seven hard supporting plates in each folding unit are isosceles right triangle hard supporting plates which are respectively a triangular plate A, a triangular plate C, a triangular plate D, a triangular plate M, a triangular plate G, a triangular plate I and a triangular plate J; wherein the set square C and the set square D form a group, the set square M and the set square G form a group, and the set square I and the set square J form a group; the two triangular plates in each group have the same shape and size;
one right-angle side of the triangular plate I and the right-angle side of the triangular plate J are arranged symmetrically left and right after being opposite, and the right-angle vertexes of the triangular plate M and the triangular plate G are arranged symmetrically left and right after being opposite; one right-angle side of the triangular plate M is opposite to the bevel edge of the triangular plate I and has the same length; correspondingly, a right-angle side of the triangular plate G is opposite to the hypotenuse of the triangular plate J and has the same length; the bevel edges of the triangular plate C and the triangular plate D are symmetrically arranged left and right after being opposite, wherein one right-angle edge of the triangular plate C is opposite to the other right-angle edge of the triangular plate M and has the same length; correspondingly, one right-angle side of the triangular plate D is opposite to the other right-angle side of the triangular plate G, and the lengths of the right-angle sides are equal; the bevel edge of the triangular plate A is opposite to the other right-angle edge of the triangular plate D, and one right-angle edge of the triangular plate D and the bevel edge of the triangular plate G are on the same straight line; gaps are arranged between any two adjacent triangular plates and are used as folding seams; wherein a folding seam is formed on the same straight line of the gap between the triangular plate I and the triangular plate J and the gap between the triangular plate C and the triangular plate D.
7. The folding composite protective shield according to any one of claims 1-6, wherein: the protective plate is characterized by also comprising a top protective structure, wherein the top protective structure is made of the same material as the protective plate; the top protective structure surrounds the top opening of the protective shield and is fixedly connected with the protective shield, and a handle is arranged on the inner side of the top protective structure.
8. The folding composite protective shield of claim 7, wherein: the top protective structure comprises a top protective plate and side protective plates connected to the left side and the right side of the top protective plate in a downward inclined mode, wherein the side protective plates are adjustable in included angle between the top protective plates to adapt to the top shape of the protective shield.
