Lock catch mechanism of hoarding box

Abstract

A lock catch mechanism of a hoarding box comprises a lock pin and stop blocks, wherein a rotary bulge is disposed on the head of the lock pin; the lower part, jointed with the stop blocks, of the lockpin is of a cuboid structure; the stop blocks are in hinged connection to the tail of the lock pin; a hinge of hinged connection is sleeved with a V-shaped spring; two ends of the V-shaped spring areadhered to surfaces of the lock pin and the stop blocks; a cylindrical bulge is disposed at the center of the lock pin; springs are compressed and installed on the upper end face and the lower end face of the bulge; the lock pin is sleeved by the springs respectively; the lock pin extends from a side wall adhered with a box cover of the hoarding box; a first through hole is formed in the side wall of the box cover of the hoarding box; a second through hole is formed in the side wall of the hoarding box; a first groove is formed by the first through hole at the spring of the corresponding lockpin; a second groove is formed in the tail part of the corresponding lock pin; the second groove is cylindrical; and distances between the two pairs of side faces are unequal.

Description

technical field [0001] The invention relates to the field of coaming boxes, in particular to a locking mechanism of a coaming box. Background technique [0002] Most of the traditional coaming boxes are integral, and their volume is fixed, corresponding to materials of different volumes, and cannot be adjusted adaptively. At the same time, when this kind of coaming box is not used, it takes up a lot of space, which is not conducive to storage. Therefore, with the development of technology, the traditional integral coaming box is gradually being eliminated. At present, most coaming boxes on the market are foldable, mainly composed of three parts: a tray, a box body, and a box cover. They have the advantages of being able to be stored and occupying a small space, but their volume still cannot be adjusted. Contents of the invention [0003] Aiming at the disadvantage that the volume of the existing coaming box cannot be adjusted, the present invention provides a coaming box ...
