Hinge structure of freezer door body

Abstract

The invention discloses a hinge structure of a freezer door body, which comprises a connecting piece, wherein the connecting piece is provided with a mounting through hole; the inside of the mounting through hole is provided with a hinge shaft; the lower end of the hinge shaft is provided with a screw socket for positioning; the hinge shaft is sleeved with a lower hinge and an upper hinge which are fit together; the fit surface between the lower hinge and the upper hinge is a cam surface formed by an inclined surface and a platform surface; the lower hinge is fixed relative to the hinge shaft; the upper hinge is circumferentially positioned in the mounting through hole of the connecting piece and can move up and down along the axial direction of the hinge shaft; the inside of the mountingthrough hole is also provided with a spring; the lower end of the spring is pressed against the upper hinge; the upper end of the spring is pressed against the connecting piece through a spring plug;and the spring plug and the hinge shaft are provided with through holes along the axial direction of the hinge shaft for the connecting wire to pass through. According to the technical proposal, the connecting wire between the freezer door body and a freezer cabinet body is concealed and arranged in the hinge structure, so the freezer door body can close effectively and automatically and the influences on freezer appearance and the easy damages to the wire caused by the exposure of the wire can be avoided.

Description

technical field [0001] The invention belongs to the technical field of door hinges, and in particular relates to a hinge structure that can be automatically closed for a refrigerator door body, especially a large refrigerator door body. Background technique [0002] The patent document with the publication number CN101135218A discloses an automatic closing structure for a large refrigerator door, which includes an L-shaped connector. A supporting wall of the L-shaped connector is provided with an installation through hole for installing the hinge shaft. A hinge shaft that can rotate around its axis is provided. The lower end of the hinge shaft extends out of the installation through hole and is formed with a screw for circumferential positioning. The hinge, the matching surface of the lower hinge and the upper hinge is a cam surface composed of an inclined plane and a platform surface. The lower hinge and the hinge shaft are relatively fixed, and the upper hinge and the conn...

Problems solved by technology

[0003] However, the existing refrigerator doors are generally of laminated glass structure, and lighting or other electrical mechanisms are arranged between the two layers of glass. These mechanisms need to be connected to the power supply on the refrigerator cabinet through wires, because the refrigerator door is a The hinge structure is connected to the cabinet body of the freezer, so the connecting wires are generally exposed on the side of the freezer close to the hinge structure, which affects the overall appearance and is not safe and easy to damage
