FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a partial cross-sectional view of the present invention;
in the figure: locating plate 1, connecting rod 2, actuating lever 3, ejector pin 4, fixing base 5, spring 6, locating hole 7, drive actuating cylinder 8.
Detailed Description
The technical scheme of the patent is further explained in detail by combining the specific embodiment;
a synchronous telescopic extrusion mechanism comprises a linkage structure which is symmetrically arranged in a quadrilateral way; the linkage structure comprises a connecting rod 2 rotatably connected to the positioning plate 1 and driving rods 3 rotatably connected to two ends of the connecting rod; the other end of the driving rod 3 is connected with one end of the adjacent connecting rod 2; an elastic extrusion device is arranged on the side wall of the inner side of the driving rod 3; the driving rod 3 is connected with a driving device; preferably, the driving device comprises a driving cylinder 8 hinged with the center of the driving rod 3, and the other end of the driving cylinder 8 is hinged with the positioning plate 1; the elastic extrusion device comprises an ejector rod 4, a fixed seat 5 and a spring 6; a positioning hole 7 is preferably arranged in the center of the fixed seat 5, a spring 6 is installed in the positioning hole 7, the side wall of the ejector rod 4 is in a step shape, one end of the ejector rod 4 penetrates through the spring 6 and the positioning hole 7, and the other end of the ejector rod is supported on the side wall of the driving rod 3.
This device drive actuating cylinder both ends and be two hinge structure, when driving actuating cylinder operation, the actuating lever can be because of the connecting rod rotation realizes controlling diagonal motion, and four actuating levers can be towards the unified corresponding elasticity extrusion device of extrusion of direction of rotation, and elasticity extrusion device is disconnected with the actuating lever, and when the actuating lever extrusion ejector pin, the ejector pin stretches out, when the actuating lever rolled back, the ejector pin can be held on the actuating lever because of the spring top.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the invention.
