Triangular waring sign

A triangular warning sign, having a structural shape of inner and outer equilateral triangles, the inner equilateral triangle is a fluorescent shining surface, and the outer equilateral triangle is a plastic optical light-reflecting surface, said sign includes:

• a triangular frame (3);
• six plastic optical fully-reflecting strips (1) secured on the front and rear faces of three edges of triangular frame (3) by ultrasonic welding;
• three fluorescent plates (2) inserted into slots on the inner side of triangular frame (3) to form double-faced fluorescent shining surfaces of an inner triangle;
• a counterweighed supporting plate (6) positioned below the triangular frame (3);
• a narrow positioning insert block (4) and some flat positioning pins (5) integrated with the bottom edge of triangular frame (3), wherein the narrow positioning insert block (4) is inserted in a supporting legs fixed seat (7), and some flat positioning pins (5) are inserted in the counterweighed supporting plate (6) and secured therein;
• fixed cuffs (8) for enveloping the two ends of counterweighed supporting plate (6);
• four supporting legs (9) hinged at the two ends of counterweighed supporting plate (6) respectively;
• a supporting legs fixed seat (7) used to secure the said four supporting legs after they are folded up;
• wherein the two lateral components of said triangular frame (3) can be foldably rotated with the two fasteners (14) at the two ends of said bottom edge as rotating centers respectively;
• the tip portions of the two lateral components of the triangular frame (3) are staggered and overlapped with each other, said tip portions are mounted with snap fasteners (13) by fusion, by which the two lateral components can be engaged with each other;
• each of the two ends of said counterweighed supporting plate (6) is provided with the hinge holes which can accommodate two supporting legs (9) having the bent end, a fixed cuff (8) envelops each of the two end portions of said counterweighed supporting plate (6) which cooperates with the fixed cuffs (8) and restrain the supporting legs (9) to rotate excessively;
• said counterweighed supporting plate (6) and said triangular frane (3) are adequately matched in weight, when put on the road, they have a good stability againt the wind.
