Description

Technical Field

[0001] The utility model relates to the technical field of containers, in particular to a locking structure used for loading and unloading containers. Background Art

[0002] Container, English name container. It is a group of tools that can load packaged or unpackaged goods for transportation and is easy to load and unload with mechanical equipment, but there are still various problems in the use process.

[0003] Publication No. CN213385928U discloses a container that is convenient for loading and unloading. The patent is provided with a positioning structure, wherein the positioning structure includes a slide bar, a limit block, a groove and a limit slot. When the limit block moves to the inside of the groove, the slide bar is released so that the slide bar moves downward along the slide slot under the action of a spring. At this time, the limit block is embedded in the limit slot under the action of the slide bar. At this time, the limit slot forms a limiting effect on the limit block, thereby avoiding the need to manually support the box door when the container needs to be filled with goods, thereby improving the applicability of the device. However, the patent still has the following problems in actual use:
