Zusammenfassung:	The utility model relates to the technical field of platform doors, in particular to a linkage type protection device which is characterized in that paired supporting columns are arranged, a first protection body and a second protection body which can ascend and descend are arranged between the two supporting columns, and the first protection body is driven by a driving mechanism to reach different opening degrees; when the first protection body and the second protection body are overlapped, the first protection body pushes the second protection body to move through the supporting piece, the opening degree of the protection device is further increased, and different opening degrees of the height position of the platform door are achieved; the distance between the supporting columns is the horizontal opening degree of the platform door, the opening degree of the platform door can be set at will, the defects that the opening degree of a flat-opening type platform door is limited and the platform space is occupi
