Movable pulley combined unit assembled on upper cross beam and lower cross beam of door leaf of wall cabinet

Abstract

The invention provides a movable pulley combined unit assembled on an upper cross beam and a lower cross beam of a door leaf of a wall cabinet, and belongs to the manufacturing technology of hardware fittings used in architectural decoration. The movable pulley combined unit assembled on the upper cross beam and the lower cross beam of the door leaf of the wall cabinet adopts the structure that an upper rail is assembled above the door leaf of the wall cabinet; and stop blocks are assembled on the upper rail and a lower rail. When the door leaf departs from a door frame edge, the stirring piece of the damper of the movable pulley combined unit can be hooked in triangular groove tables of the stop blocks and pull the top chord of the damper; and when the door leaf goes back to the door frame edge, the stirring device of the damper can generate a damping action to ensure that the door leaf goes back to the door frame edge slowly and safely without the phenomena of beating and collision. The movable pulley combined unit has the advantages of novel design, reasonable structure, compact components, convenience in mounting and adjusting, and obvious effect. The movable pulley combined unit comprises components such as an adjusting bolt (1) and a movable pulley (2), and is characterized in that the movable pulley combined unit (18) is assembled on a door leaf upper cross beam (2) and a door leaf lower cross beam (3); the upper rail (19) is mounted above the door leaf (6); and the stop blocks (20) are mounted on the upper rail (19) and the lower rail (20).
