Abstract

The invention relates to a single-column double-point inward-opening type invisible safety door. The safety door at least comprises a door frame and a door plate; the door frame is connected with the door plate through door lugs and a door shaft. The safety door is characterized in that the central axis of the door plate is connected with an operating hand wheel, the operating hand wheel is provided with a small gear, the small gear is coupled with a big gear arranged at the lower end of the central axis, and the left side and the right side of a gear plate of the big gear are connected with a set of link mechanisms and door holder mechanisms respectively; the door holder mechanisms are connected through the left link mechanism and the right link mechanism, compressing and separating are conducted by compressing wedges of the door holder mechanisms and a left frame and a right frame of the door frame. The safety door has the advantages that the safety is high, the use is convenient, and the technology is reasonable.

Description

technical field [0001] The invention relates to a safety door, in particular to a single-column double-point inner-opening invisible safety door. Background technique [0002] In recent years, there have been piracy activities in many international navigation areas around the world, and they have become more and more rampant.
