Balancing device of foldable container

Abstract

The invention discloses a balancing device of a foldable container. The device comprises a hinge which is used for connecting a bottom frame of the container to an angle post of the container and a guide rod, wherein the guide rod is fixed to the bottom frame of the container, the central axis of the guide rod is vertical to the plane of the end wall of the container, an elastic part is sleeved on the guide rod, a first limiting part is arranged at one end of the guide rod, a sliding sleeve which can slide on the guide rod freely is arranged in the middle of the guide rod, and the first limiting part and the sliding sleeve limit the elastic part from two ends of the elastic part. The device has the advantages that the rigidity coefficient of the elastic part is large, the safety performance is good, the buffering effect is achieved when the end wall is folded, the force assisting effect is achieved when the end face is unfolded, the requirement for the elastic part is reduced, the cost is reduced, the universality is good, and the device is suitable to container bottom frame platforms of different heights.

Description

technical field [0001] The invention relates to a foldable container, in particular to a balance device for a foldable container. Background technique [0002] A folding container is a container with a foldable end wall, and the end wall of the folding container is generally hinged to the container chassis through a pivot. The end wall has two positions: vertical and folded. When the end wall is in the vertical position, it can be used as a platform container by locking it with a locking pin; when the end wall is in the folded position, it can be used as a platform container or stacked with other folding boxes. Yard, saving transportation and storage space. [0003] In order to facilitate the folding operation of the end wall, a balance device is provided on both sides of the end of the bottom frame platform, which acts as a buffer when the end wall is folded toward the bottom frame platform; when the end wall is manually lifted from the bottom frame platform, the The bala...

Problems solved by technology

The form of the leaf spring is mostly used when the height of the underframe platform is small; the form of the oil cylinder is expensive, the structure is complicated, and oil leakage often occurs; and the form of the tension spring is used when the height of the underframe platform is small, because there is no The appropriate space for installing the spring pull arm makes it impossible to use the tension spring; and due to the limitation of the performance of the existing spring material, the spring end pull hook wound by the steel wire is often broken. When the foldable end wall is very heavy When the tension spring is broken, or it is difficult to achieve effective buffering and boosting effects, if the tension spring breaks, the spring will fly out and hurt people due to stretching and accumulating force; the end wall loses the balance force of the spring, Falling down will also damage the goods or injure people, posing a safety hazard
