Packaging box structure

Abstract

A packaging box structure is used for packaging a glass substrate and comprises a box body, a box cover and limiting grilles. The box body comprises a bottom plate and box walls connected to the bottom plate; a containing cavity is defined by the bottom plate and the box walls, and a plurality of first limiting protruding strips are arranged in the containing cavity of the box body; the first limiting protruding strips are connected to the bottom plate and the two opposite box walls; a first limiting groove is formed between every two adjacent first limiting protruding strips, and the box body is provided with a box opening; the box cover can be buckled on the box opening of the box body and seals the containing cavity, and the limiting grilles are arranged between the box body and the box cover; a plurality of limiting plates which are arranged in a spaced manner are arranged on the limiting grilles, and the limiting plates are vertically arranged in the direction perpendicular to the bottom plate; a limiting slot is formed between every two adjacent limiting plates and corresponds to the corresponding first limiting groove; and the glass substrate can penetrate the limiting slots of the limiting grilles and is limited in the first limiting grooves of the box body. The packaging box structure can prevent the glass substrate from being bent, and fractions caused by extrusion of the glass substrate are avoided.

Description

technical field [0001] The invention relates to the field of glass storage boxes, in particular to a packing box structure. Background technique [0002] Usually, the glass substrate needs to be transported to the next processing site for further processing after production. In order to achieve the purpose of reducing damage rate, waterproof, dustproof and shock resistance, the glass substrate is packed in a packaging box when transported. [0003] figure 1 It is a schematic diagram of the split structure of the existing packing box structure. figure 2 It is a schematic cross-sectional structure diagram of an existing packaging box structure encapsulating a glass substrate. Such as figure 1 and figure 2 As shown, the packaging box structure 200 includes a box body 210 and a box cover 220. The box body 210 includes a bottom plate 212 and four box walls 214 connected to the bottom plate 212. The bottom plate 212 and the box walls 214 are formed to accommodate the glass s...

Problems solved by technology

[0004] However, when the packaging box structure 200 packs a large and thinned glass substrate 20a, since the glass substrate 20a is vertically arranged in the box body 210, the side of the glass substrate 20a is not supported and limited, so that the glass substrate 20a is easy to produce Bending, when the box cover 220 is fastened on the box body 210, the side of the glass substrate 20a away from the bottom plate 212 is out of alignment with the second limit groove 205 of the box cover 220, and the glass substrate 20a is pressed against the box cover 220 Between the box body 210, it is easy to cause the glass substrate 20a to break

Moreover, the glass substrate 20a is likely to cause poor optical performance after being bent.
