Description

Technical Field

[0001] The utility model relates to the technical field of metal cage preparation, in particular to a metal cage locking mechanism. Background Art

[0002] The metal frames or cages for placing objects are generally produced into single structures according to requirements. By fixedly connecting several hook-shaped fasteners under the upper metal frame or cage to hook the lower metal frame or cage, a detachable multi-layer structure is formed. In this way, it is not only convenient for packaging and transportation, but also saves production time and improves efficiency. However, even if the metal frame or cage is produced into a single structure, the space it occupies is still not small, and the frame-shaped or cage-shaped structure is prone to deformation due to collision during transportation, affecting the appearance and causing the upper and lower layers to be unable to be connected. If additional protective structure packaging is added, the transportation cost will increase. And only by installing hook-shaped fasteners at the bottom of the upper metal frame or cage to hook the lower metal frame or cage, the upper and lower metal frames or cages are prone to shaking, resulting in poor connection stability of the overall metal frame or cage after installation.

[0003] Therefore, on the basis of splitting the metal frame or cage into multiple flat plate-shaped metal fences to facilitate packaging and transportation and save transportation costs, the research purpose of the utility model is to design a metal cage locking mechanism that can quickly and conveniently assemble each metal fence into an integral metal cage, splice multiple metal cages into an upper and lower multi-layer structure, and ensure strong assembly stability and adaptability.
