Description

Technical Field

[0001] The present application belongs to the field of composite material packaging boxes, and in particular relates to a structure for improving the sealing performance of a composite material packaging box. Background Art

[0002] Composite packaging boxes are gradually replacing wooden packaging boxes and becoming the mainstream product in the field of precision equipment protection and transportation due to their better environmental adaptability, longer service life and lower manufacturing costs.

[0003] Existing composite material packaging boxes are generally composed of an upper box, a lower box and functional accessories. In order to facilitate lifting and transportation, a lifting ring is generally set at the top reinforcement rib of the upper box. During the lifting process, the weight of the packaging box and the contents are transmitted downward through the lifting ring, the upper box, the sealing lock, the lower box and the base in sequence. The lifting ring and the upper box will be subjected to a large force, causing the upper box to deform significantly. In order to reduce the deformation of the upper box, it is necessary to increase the wall thickness of the upper box to increase the rigidity. At the same time, reinforcement ribs are set at the connection position between the lifting ring and the upper box by stacking to enhance the overall rigidity of the upper box and the safety of the lifting ring connection. During the lifting and transportation of existing composite material packaging boxes, the transmission method of the gravity between the built-in objects and the packaging box is unreasonable, and the lifting ring, upper box body, lock buckle, lower box body, and base are required to bear the weight. The upper and lower box bodies have insufficient rigidity, and the deformation at the joint surface of the upper and lower box bodies is large, and the sealing effect is poor. Strengthening the packaging box rigidity by increasing the wall thickness of the upper and lower box bodies, setting reinforcing ribs, etc. will significantly increase the weight of the packaging box, causing inconvenience in use and transportation, and increasing the manufacturing cost.

[0039] In a preferred embodiment of the present application, reinforcing ribs are provided on the outside of the upper box body 2 and the lower box body 7. Preferably, a plurality of reinforcing ribs are provided at equal intervals along the circumference of the box body, and reinforcing ribs are provided along the axial direction of the upper and lower side walls of the box body. Figure 4 As shown, in this embodiment, the upper box body 2 and the lower box body 7 have a composite material body 9, and a metal frame 10 is embedded inside the composite material body 9 with a reinforcing rib position. By embedding the metal frame 10 inside the composite material body 9 of the composite material packaging box, the overall rigidity of the box wall is enhanced, the use of composite materials is reduced, and the weight and manufacturing cost of the packaging box are effectively reduced.

[0040] In the preferred embodiment of the present application, the upper hanging plates 3 are installed on the reinforcing ribs of the upper box body 2 by bolts, and multiple groups of the upper hanging plates 3 are symmetrically arranged on the opposite side walls of the upper box body 2; the lower hanging plates 5 are installed on the reinforcing ribs of the lower box body 7 by bolts, and multiple groups of the lower hanging plates 5 are symmetrically arranged on the opposite side walls of the lower box body 7. The composite material packaging box and the internal objects are hoisted by dispersing the gravity through multiple groups of upper hanging plates 3 and lower hanging plates 5, thereby improving the hoisting stability.

[0041] In a preferred embodiment of the present application, the base includes: a crossbeam, a longitudinal beam and a positioning block, wherein the crossbeam includes two, the two crossbeams are arranged in parallel, and the distance between the two crossbeams is adapted to the bottom box width of the composite material packaging box; the longitudinal beam includes at least two, all longitudinal beams are vertically installed on the crossbeam, and the two ends of the longitudinal beam are respectively connected to the corresponding crossbeam; the positioning block includes multiple groups, each group includes two positioning blocks, the two positioning blocks in the same group are symmetrically installed on the corresponding crossbeam, the positioning blocks and the crossbeam are fixed by welding, the upper end faces of the two positioning blocks in each group are arranged in a V shape, and the upper end faces of the positioning blocks are at the same inclination angle as the bottom mounting surface of the composite material packaging box.

During the lifting process of the composite material packaging box, the gravity of the composite material packaging box and the internal objects is transmitted to the lifting ring 1 in turn through the base, the lower hanging plate 5, the pin 6, and the upper hanging plate 3, and the gravity is all borne by the metal structural parts. The metal parts have high rigidity and small deformation. The box body itself is not affected by external forces, the box body has small deformation, and the sealing effect is good.

[0045] The structure of the present application for improving the sealing performance of the composite material packaging box improves the transmission mode of gravity between the composite material packaging box and the internal objects. The composite material packaging box is not affected by external forces during the lifting process and has a good sealing effect. The metal frame 10 is laid inside the wall of the composite material packaging box to greatly enhance the overall stiffness of the composite material packaging box. Compared with a pure composite material box with the same stiffness, the present application is lighter, uses less composite material, and has a lower manufacturing cost.
