Side opening door box

Abstract

The invention discloses a side opening door box. The lateral surface of the side opening door box is provided with side door components. Each side door component comprises a doorframe and a plurality of door leaf components, wherein at least one door leaf component comprises at least two door leaves; adjacent door leaves are connected by pivots and are tightly attached after the door leaf component is opened; at least one door leaf component is connected to one of a door lintel and a doorsill through a suspension device; the suspension device comprises a guide rail, a roller group, a fixing part, a connecting rod and a tension spring; the guide rail is fixed on one of the door lintel and the doorsill; the roller group comprises a plurality of rollers which are arranged in the guide rail and can roll along the guide rail; the fixing part comprises a first end and a second end; the first end is fixed on one door leaf of the door leaf component; one end of the connecting rod is rotatablely connected to the roller group and the other end of the connecting rod is rotatablely connected to the second end of the fixing part; and the torsion spring is connected between the roller group andthe second end of the fixing part. The door leaf components of the side opening door box can realize folded opening, so that the rotating radius when the side opening door box is opened is reduced. Moreover, due to the arrangement of the suspension device, the lower hanging amount of the door leaf components can be reduced.

Description

technical field [0001] The invention relates to a side-opening door box, in particular to a side-opening door box with a middle column on the door frame. Background technique [0002] Existing side door boxes are generally 20' side door boxes, at least one side of which is provided with a side door assembly. The side door assembly includes a door frame fixed on the box and a door leaf oppositely mounted on the door frame. A door frame usually includes a lintel, a sill, two side posts on the left and right sides of the door frame, and a middle post between the two side posts. [0003] Existing side-opening door assemblies generally only include two relatively openable door leaves, and each door leaf is respectively connected to a side doorpost. During the opening process, the rotation radius of the door leaf is large, that is, a large side opening space is required. Therefore the side door assembly of this structure is not suitable for being arranged on the longer side doo...

AI Technical Summary

Problems solved by technology

Therefore the side door assembly of this structure is not suitable for being arranged on the longer side door box

In addition, the hanging amount of the door leaf assembly is large, resulting in a large gap between the door leaf assembly and the door frame, and it is difficult to ensure the sealing between the door leaf assembly and the door frame in the closed state

Moreover, the self weight of the door leaf assembly can easily lead to deformation or even damage of the hinge connected between the door leaf assembly and the corresponding door post.
