Balanced pressure lever mechanism and escape door lock

Abstract

A balanced pressure lever mechanism and an escape door lock, the balanced pressure lever mechanism comprises a seat plate and a flat push cover, a plurality of connecting rod assemblies are arranged between the seat plate and the flat push cover, one end of the connecting rod assembly is rotatably connected with the seat plate, the other end of the connecting rod assembly is rotatably connected with the flat push cover, the flat push cover is pressingly movable on the seat plate through the connecting rod assembly, and the connecting rod assemblies are distributed along the length direction of the flat push cover, so that the flat push cover keeps active balance when pressing the flat push cover at different positions. The balanced pressure lever mechanism of the utility model is provided with a plurality of connecting rod assemblies between the seat plate and the flat push cover, the connecting rod assemblies are distributed along the length direction of the flat push cover, so that the flat push cover keeps active balance when pressing the flat push cover at different positions, that is, when one end of the flat push cover is pressed, the other end of the flat push cover will not be raised, the accurate action of the flat push transmission part is guaranteed, thereby effectively unlocking the escape door lock, and the use experience of the user is greatly improved.
