Abstract

The invention discloses a power-assisted door handle assembly and refrigeration equipment, comprising a bracket, a handle, a push rod and a return spring arranged on the bracket. The side wall of the bracket is provided with a first rotating rod and a second rotating rod. The first rotating rod and the second rotating rod are parallel to each other and the lengths of the two are different. The upper ends of the two are connected with the handle respectively. The lower ends of the elders are connected to the push rods, and the upper ends of the two are closer to the cabinet of the refrigeration equipment than the lower ends. Two connecting points between the first rotating rod and the second rotating rod and the bracket, and two connecting points between the first rotating rod and the handle enclose a parallelogram. When the handle is pulled, the upper ends of the first rotating rod and the second rotating rod move away from the box body, and the lower end of the longer one of the two moves toward the direction close to the box body, driving the push rod toward the direction close to the box body Move to abut against the box body, use the force acting on the box body to overcome the pressure difference between the inside and outside of the storage room, and realize the easy opening of the door body.

Description

technical field [0001] The invention relates to the technical field of door handles of refrigeration equipment, in particular to a power-assisted door handle assembly and refrigeration equipment. Background technique [0002] The door body and box body of refrigeration equipment such as refrigerators or vertical freezers are generally sealed by magnetic sealing strips to prevent the cold air in the storage room from leaking out, so as to ensure the cooling effect. But when opening the door body, because there is a pressure difference between the storage room and the outside, under the joint action of negative pressure and magnetic force, it is more laborious to open the door body. Some existing handles with power-assisted structures generally have complicated structures. Contents of the invention [0003] The technical problem to be solved by the invention is: the invention proposes a power-assisted door handle assembly and refrigeration equipment, which has a simple stru...
