Composite sealing packaging box

Abstract

The invention specifically relates to a composite sealing packaging box. By adopting the composite sealing packaging box, the problems that a composite packaging box is poor in structural strength, and a lifting tool damages the packaging box are solved. According to the composite sealing packaging box, the inner wall of a box cover and the inner wall of a box body are provided with annular reinforcing ribs and longitudinal reinforcing ribs; the edges of the box cover and the box body are provided with box opening frames; the annular reinforcing ribs and the longitudinal reinforcing ribs extend to the box opening frames; the box opening frames are provided with box sealing parts; a bracket is arranged in the box body; the bracket is fixed through bracket retaining ribs fixed to the inner wall of the box body and bracket locating pins arranged on the bracket; a U-shaped steel frames and cushion pads are arranged between the brackets and the box body; stacking reinforcing ribs are arranged in the positions, corresponding to the brackets, of the outer side faces of the box cover and the box body; the top faces of the stacking reinforcing ribs are provided with stacking pins and box cover lifting rings, and the outer side faces of the stacking reinforcing ribs are provided with bumper blocks and fixed angle lifting rings. The composite sealing packaging box is reasonable in structure design. Reasonable reinforcement of the box body is realized while the sealing performance is guaranteed. Meanwhile, the problem that box bodies are damaged in the lifting process is solved. The composite sealing packaging box is low in cost and long in service life.

Description

technical field [0001] The invention relates to an industrial packing box, in particular to a composite material sealed packing box. Background technique [0002] With the continuous development of new materials, composite materials such as glass fiber reinforced plastics, basalt fibers, and carbon fibers are gradually applied in packaging boxes. For larger packaging boxes, there are large differences in the stress of different working conditions such as hoisting, fork loading, and stacking storage during use. Due to the anisotropic characteristics of composite materials, the structural rigidity of the packaging box is high, especially the packaging box with sealing requirements. It is a difficult problem to reduce the weight of the packaging box while controlling the deformation of the packaging box and ensuring the sealing performance. [0003] In order to facilitate hoisting, most of the composite material packaging boxes are lifted by the box lid. This lifting method ha...
