Hinges for folding container

Abstract

The invention provides a hinge pair used for a folding container, more particularly, a hinge pair with dual-hinge structure used for the folding container. The invention comprises an upper hinge plate, a lower hinge plate and a hinge; the upper hinge plate is fixed on the side wall of the folding container; the lower hinge plate is fixed on the base of the folding container; the upper hinge plateand the lower hinge plate are connected by the hinge; the hinge consists of a hinge body, an upper hinge pin and a lower hinge pin. The invention solves the problem that the side wall is mutually interposed and can not be tightly attached to each other when the folding container is folded and the folding container hinge device is easy to be blocked, makes up the shortage of the prior art that a folding turnover box can be only rotated and can not implement the free motion in two DOF. When the folding container where the invention is applied to is folded, the relative side walls are tightly attached and the volume is small after folding; the invention is convenient for folding, piling and transporting and reduces the transportation cost.

Description

technical field [0001] The invention relates to a hinge pair for a folding container, in particular to a hinge pair with a double hinge structure for a folding container. Background technique [0002] As a carrier of logistics, turnover boxes have been used in various occasions for a long time. Ordinary turnover boxes are fixed frame structures, which take up a lot of space when they are empty. Therefore, people consider using folding forms to improve them. The foldable turnover box has the characteristics of simple structure, elegant appearance, small footprint after folding, can reduce the transportation cost of fruits and vegetables, is suitable for stacking empty boxes for long-distance transportation, and can be widely used in industries such as fruits and vegetables, food and beverage, and wine making. The foldable turnover box can be folded and used for turnover. It is suitable for the turnover of materials in various vehicles such as trains, automobiles, airplanes, a...

AI Technical Summary

Problems solved by technology

In order to solve the problem of convenient folding storage and transportation of folding containers, the hinge pair used for folding containers of the present invention adopts a double hinge structure, which makes folding and unfolding of folding containers such as turnover boxes convenient and flexible, and reduces the storage space of folding containers

[0005] The invention solves the problems that the relative side walls of the folding container interfere with each other and cannot be closely fitted and the hinge device of the folding container is easily stuck when the folding container is folded, and makes up for the fact that the folding turnover box in the prior art can only rotate and cannot achieve two degrees of freedom lack of freedom of movement
