Box cover for matching coaming box

Abstract

The invention discloses a box cover for matching a coaming box. The box cover comprises a box cover main body, wherein the box cover main body is formed by combining a left box cover and a right box cover through the plug-in connection of a plug-in plate and a plug-in hole; the side face, towards to the inside of a box body, of the box cover main body is provided with a telescoping mechanism; thetelescoping mechanism is arranged in the middle in the box cover main body and comprises fork rods which are crossed and rotationally connected; the two ends of the fork rods are respectively connected with the left box cover and the right box cover; a pair of side faces, outside the box body, of the box cover main body is provided with limit mechanisms; each limit mechanism includes a lock catch,a spring bolt and a sliding buckle; the lock catches comprise base blocks; bending plates are rotationally installed on the base blocks through rotating shafts; each bending plates is in an obtuse angle V shape; a projectile is pressed between the upper half part of each obtuse angle V shape and each base block; and the end of the lower half part of each obtuse angle V shape extends into the empty space. The box cover for matching the coaming box can extend the width of the box cover according to the width extension of a coaming box tray so as to achieve the overall structure of the coaming box, and the structure is stable and the operation is simple.

Description

technical field [0001] The invention relates to the field of coaming boxes, in particular to a box cover for coaming boxes. 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. [0003] In order to solve the above problems, a coaming box pallet that can be adjusted in width has appeared. For the general coaming box cover, it cannot be stretched in width a...

Problems solved by technology

At present, most of the coaming boxes on the market are foldable, mainly composed of three parts: tray, box body, and box cover. It has the advantages of being able to store and occupying a small space, but its volume still cannot be adjusted.

[0003] In order to solve the above problems, a coaming box pallet that can be adjusted in width has appeared. For the general coaming box cover, it cannot be stretched in width and cannot meet the requirements of the coaming box pallet with adjustable width. needs
