Packaging box with height adjusting function

Abstract

The invention discloses a packaging box with a height adjusting function. The packaging box comprises a box body and a box cover located at the top of the box body; the packaging box is characterized in that sliding grooves are formed in the two sides of the inner wall of the box body, movably plates matched with the sliding grooves are arranged in the sliding grooves and can move in the sliding grooves, transverse rods are arranged on the side faces of the movable plates, a flat plate is arranged between the two transverse rods, and the transverse rods are both connected with the flat plate; and when the movable plates move in the sliding grooves, the flat plate moves along with the movable plates, grooves are further formed in the sliding grooves, limiting rods are further arranged on the side walls of the movable plates and are connected with the movable plates through threads, the rotating rods are rotated, and the tail ends of the limiting rods can be moved into the grooves. According to the packaging box, the movable plates are pulled, the height of the flat plate can be increased, and therefore objects are easily placed into the box body, and the working efficiency is improved; and meanwhile, the damping function is achieved, and swing of the objects in the transporting process can be reduced.

Description

technical field [0001] The invention relates to the field of packaging boxes, in particular to a packaging box with a height adjustment function. Background technique [0002] Packaging box is a necessity in enterprise production and logistics transportation.

Wooden packaging boxes are packaging containers made of wood and bamboo; fumigation-free packaging boxes are made of composite materials. Packaging container packing box; strong plastic safety box is a packaging container made of patented engineering plastics through a special process; The widest range of packaging products. Packaging boxes can be divided into ordinary wooden boxes, aluminum alloy b...

AI Technical Summary

Problems solved by technology

[0003] At present, with the continuous development of the economy, packaging boxes are more and more widely used, especially some larger frame wooden boxes. However, due to their large volume and deep inner bottom, when packing items, Due to the limited length of the arm, it is difficult to place the item on the inner bottom of the box smoothly, so most of the items are lifted by a lifting device, and then the item is slowly put into the box. Bundling and unbundling is cumbersome, and it is difficult to safely place the items in the packing box without a lifting device; at the same time, most packing boxes do not have the function of shock absorption, so the items are easy to be damaged during transportation
