Hidden hinge and container using same

Abstract

The invention provides a hidden hinge and a container using the same. The hidden hinge is applied to the connection between a side door and the side wall of a container, and comprises an upper hinge mount, a hinge main body and a lower hinge mount; and the hidden hinge is characterized in that the upper hinge mount is provided with an upper groove for accommodating a hinge pin, the lower hinge mount is provided with a lower groove for accommodating a hinge pin, the appearance of the hinge main body is approximately U-shaped, and the two open ends of the U-shaped hinge main body are respectively provided with a hinge pin matched with the upper groove or the lower groove. The hinge provided by the invention is hidden between the side wall and side door of the container, so that the hinge can not be seen from the appearance of the container, thereby greatly improving the product appearance. Meanwhile, due to a controllable hinge rotating sequence, the side door turns over more smoothly, thereby effectively improving the convenience of operation.

Description

technical field [0001] This invention relates to hinges, in particular to concealed hinges for containers. Background technique [0002] As we all know, it is very common to use containers to carry or transport various materials, and these containers have a series of specifications from large to small. For the convenience and quickness of production turnover or transportation and cost savings, plastic material containers have also begun to be widely used. Most of these containers have a bottom and four side walls, and the side walls are integrated or foldable. When the volume of the container is large, it is often necessary to have an openable door on one or more side panels to facilitate access to the bottom of the container or to install and remove some additional components at the bottom. The openable door is normally flush with the side panel and has a locking mechanism to secure it against accidental opening. If it needs to be opened, the door is turned outward about ...

AI Technical Summary

Problems solved by technology

But there are also some shortcomings, such as the rotation sequence of the two pins is not easy to control, in order to prevent interference during rotation, it is necessary to place a large gap between the bottom of the side door and the side plate or pour a large fillet

Secondly, for the installation of the hinge device, the structure of the side door and the side panel is often dug with many holes, which greatly damages the overall appearance, and this structure usually requires a special locking device to limit the opening and closing of the door
