Description

Technical Field

[0001] The invention relates to the technical field of cabinet limit accessories, in particular to a door stop assembly for a double-door cabinet. Background Art

[0002] Various types of double-door cabinets lack effective sealing measures at their double doors, making it difficult to improve their IP rating (protection level). Double-door cabinets are relatively wide, and the left and right doors become movable cantilevers with the hinges as the rotation center after opening. The strength requirements for the frame and hinge kit are higher than those for single-door cabinets. After the double-door cabinet's door is closed and locked, a certain amount of elastic deformation space needs to be reserved at the cross-overlapping part of the door to cope with the elastic deformation of the cabinet shell or frame generated during the lifting and logistics process. The sealing performance and elastic deformation absorption capacity of existing double-door cabinets often fail to meet usage requirements. Summary of the invention
