Container and locking mechanism thereof

Abstract

The invention discloses a locking mechanism which is used for locking an upper cover of a container on a container side plate. The container comprises a base, the upper cover and side plates, wherein the upper cover is provided with a safe edge. The locking mechanism comprises a locking piece, a driving piece, a resetting piece, lock holes and a groove, wherein the lock holes are formed in the outer side of at least one side plate, and the groove is formed in the upper cover; one end of the locking piece is arranged in the groove, and the other end of the locking piece is provided with a lock head; the lock head penetrates through the safe edge and can extend into one of the lock holes along a direction vertical to the corresponding side plate, so that the upper cover is locked to the corresponding side plate; the driving piece is arranged in the groove and is used for driving the locking piece to perform unlocking, and the resetting piece is arranged in the groove and is used for resetting the driving piece after unlocking is finished. According to the container and the locking mechanism, the transportation cost and the storage cost can be lowered and the labor intensity of operators is alleviated.

Description

technical field [0001] The invention relates to a container, in particular to a locking mechanism for the container. Background technique [0002] Generally, a large container has four side panels and a bottom, and a large container for transporting liquid or bulk cargo often also has an upper cover to protect the goods loaded inside. There is a ring of guards around the upper cover, which are close to the outer sides of the four side plates of the container. When the goods inside the container exert a large force on the side plates, the guards of the upper cover can protect the side plates from deformation to a certain extent is too big. In addition, when the liquid or bulk goods in the container fluctuate upwards, the upper cover can well limit the ups and downs of the liner bags containing them, thereby also protecting the liner bags from being damaged. This requires that the upper cover can be reliably connected with the box body during use. In addition, most of the f...

AI Technical Summary

Problems solved by technology

This solution reduces the specific operation of locking the side panels and avoids the damage of related parts on the upper cover. However, due to its thick thickness and not being located directly above the side panels, the concave part on the upper cover of the product after folding The groove cannot be well hidden by the structure of the bottom of the box, so that the cumulative height after folding is relatively high, which is not conducive to transportation and increases storage costs. Moreover, when the box is full of liquid, the side panels will expand outward under pressure, which will cause The depth of the lock tongue inserted into the side plate pit becomes shallower, which greatly reduces the reliability of the lock catch

[0005] The above existing technical solutions also have a common defect, that is, when unlocking, it is necessary to run the sides where the two locks are located to unlock respectively, which makes the operator's workload heavy
