Single-column double-point inward-opening invisible safety gate link mechanism
The invention relates to a single-column double-point inward-opening invisible safety gate link mechanism, characterized by being divided into a left link mechanism and a right link mechanism which are the same in structure. Each of the left link mechanism and the right link mechanism at least comprises a first connecting rod and a second connecting rod; certain ends of the first connecting rods are connected with a big gear plate shaft; the other ends of the first connecting rods are connected with the second connecting rods by connecting plates; the second connecting rods are parallel to left and right edges of a door frame, and are provided with multiple door holder mechanisms from top to bottom; the door frame is connected with a door panel by door lugs and a door shaft; the central axis of the door panel is connected with an operation hand wheel. The single-column double-point inward-opening invisible safety gate link mechanism has the characteristics of high safety, good convenience in use, reasonable process, and the like.
