Storage device that can be opened and closed by rotating

Abstract

The invention discloses a storage device capable of being rotationally opened and closed. The storage device comprises multiple containers which are connected through a mandrel in a stacked manner. A movable wheel frame is connected to the bottom end of the mandrel. The movable wheel frame is connected with the container on the second layer through a linkage piece and the movable wheel frame and the container on the second layer move at the same time. A second wheel set is arranged on the movable wheel frame. A first wheel set is arranged at the bottom of the container on the bottom layer. Each container is provided with a push contact piece extending downwardly, each push contact piece is capable of laterally pushing the side wall of the container under the push contact piece, and the container below the container on the top layer can be continuously driven to be rotationally closed or opened by horizontally pushing and pulling the container on the top layer; during closing, the first wheel set and the second wheel form a first support bottom area to stably support the closed storage device; and when the containers of the storage device are rotated and opened outwardly, the movable wheel frame and the second wheel set form a second support bottom area larger than the first support bottom area. No matter in the rotational outwardly-opening process or in the rotational closing process of the containers, the sufficient support bottom area support can be obtained, and no tilting problem exists.

Description

technical field [0001] The present invention is a storage device, more specifically, a storage device that can be opened and closed by rotation. Background technique [0002] A typical multi-container storage device adopts a fixed shelf to store containers, and the containers can be opened and closed by horizontal push-pull back and forth in the shelf, and the push-pull opening and closing direction of each container is the same. When this typical storage device is in use, all the containers cannot be opened at the same time, because there will be a problem that the upper container will cover the lower container. [0003] The rotating opening and closing storage device can solve the above problems, such as DE20002747U1, which has a plurality of stacked upper opening containers, and a mandrel passes through the eccentric sleeve part of the container in sequence, and a group of large Wheel set, a small wheel set is affixed to the bottom of the lowest container. Each containe...

AI Technical Summary

Problems solved by technology

Since the large wheel set and the small wheel set are fixed, the area of ​​the supporting bottom formed by them is limited, so the misalignment opening angle of each container is greatly restricted. Every container is opened, and the upper layer cannot be completely avoided. The problem that the container shadows the underlying container

In addition, each container is independently expanded, without interlocking design, and there is no function of driving the wheel set at the same time
