Title:
DOOR SHAFT SYSTEM THAT IS EASY TO ASSEMBLE AND DISASSEMBLE AND CAPABLE OF BEING DISENGAGED UNDER STRESS, AND VEHICLE-MOUNTED REFRIGERATOR USING DOOR SHAFT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/216950
Kind Code:
A1
Abstract:
Provided in the present invention is a door shaft system that is easy to assemble and disassemble. The door shaft system comprises a box body and a door body, wherein a shaft body is arranged on the box body; a shaft sleeve is arranged on the door body; a limiting device is arranged on the door body and/or the box body; the shaft sleeve is made of an elastically-deformable material; and the door body and the box body are connected to each other by means of the shaft body and the shaft sleeve. The limiting device limits the rotation of the shaft body in the shaft sleeve when the door body is completely opened; and when the door body is completely opened, the distance between two opposite shaft sleeve sliding contact surfaces of the shaft sleeve during elastic deformation under the interaction of the gravity of the door body, the limiting device, the shaft body and the shaft sleeve is less than the diameter of a cylinder where the shaft body is positioned; and the distance between the two opposite shaft sleeve sliding contact surfaces of the shaft sleeve during elastic deformation under the interaction of a force F that is applied to the door body, the limiting device, the shaft body and the shaft sleeve can be greater than or equal to the diameter of the cylinder where the shaft body is positioned.
