TECHNICAL FIELD

[0001] The utility model relates to packing box technical field especially is related to a reinforcing assembly for paper packing box. BACKGROUND

[0002] The honeycomb paper box is made by stamping, cutting and pasting honeycomb paper board, and the paper board interface is pasted with paper corner guards for reinforcement. It can be designed into different configurations such as integral type, combined type (detachable) and integrated bottom support type according to actual needs, which is more convenient for carrying and loading and unloading.

[0003] Paper packing boxes are the most common, and at the present stage, the top and bottom of the packing box are mostly packaged by folding and using adhesive tape, and the opening is prone to deformation and damage. The goods transported inside are prone to shaking. SUMMARY

[0004] In view of the above technical problems of the prior art, the technical problem to be solved by the present application is to provide a reinforcing assembly for paper packing box with simple structure and good protection effect.

[0005] In order to solve the above technical problems, the utility model adopts the following technical scheme:

[0006] A reinforcing assembly for paper packing box, comprising a reinforcing frame arranged at the opening of the top and bottom of the packing box, the reinforcing frame comprising two parallel long rods, the two long rods being fixedly connected by a plurality of short rods, the middle part of the short rod being fixed by a connecting rod arranged in parallel with the long rod; the cross section of the long rod, the short rod and the connecting rod is square, and the long rod, the short rod and the connecting rod are provided with a supporting assembly inside; the long rod and the short rod are provided with a reinforcing assembly between them, and the short rod and the connecting rod are provided with a reinforcing assembly between them.

[0007] In use, the reinforcing assembly, i.e. the reinforcing frame, is placed at the bottom of the packing box, and after the goods are filled, the reinforcing frame is covered again, and finally the packing box is packaged. The reinforcing frame can prevent the goods from directly contacting the top and bottom of the packing box, thereby preventing deformation and damage to the packing box. The supporting assembly in the long rod, the short rod and the connecting rod can prevent vertical deformation and ensure the reinforcing effect. The reinforcing assembly can ensure the stability between the parts and prevent horizontal deformation. The present scheme has the advantages of simple structure and good reinforcing effect

[0008] As an optimization, the supporting assembly comprises two groups of W-shaped bent plates, and the two groups of bent plates are inserted together from the vertical direction to form an X-shaped support.

[0009] In this way, when the long rod, the short rod and the connecting rod are subjected to vertical extrusion, the interaction force between the X-shaped supports formed by each other can ensure that they will not be crushed, thereby ensuring the vertical stability and supporting strength.

[0010] As optimization, the reinforcing assembly comprises reinforcing ribs arranged between the long rod and the short rod and between the short rod and the connecting rod.

[0011] In this way, the reinforcing ribs can prevent extrusion in the horizontal direction from deforming the reinforcing frame in the horizontal direction, thereby ensuring the use effect.

[0012] As optimization, the reinforcing ribs comprise L-shaped plates, connecting plates are arranged between the L-shaped plates, and sealing plates are arranged at the top and bottom of the L-shaped plates.

[0013] In this way, the reinforcing ribs can limit the horizontal direction, and the connecting rods can prevent the reinforcing ribs from being extruded in the vertical direction, thereby increasing the quality of the reinforcing ribs.

[0014] As optimization, the long rod, the short rod and the connecting rod are all folded from a single sheet of paper.

[0015] In this way, the structure is simple, the manufacturing is convenient, and the cost is reduced.

[0016] In summary, the reinforcing assembly for the paper packaging box has the advantages of simple structure and good protection effect. BRIEF DESCRIPTION OF DRAWINGS

[0022] The present application will be further described in detail below with reference to the drawings. In the description of the present application, it should be understood that the orientation words such as "up", "down", "top", "bottom" and the like indicate the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and in the absence of contrary description, these orientation words do not indicate or imply that the indicated device or element must have a particular orientation or be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the scope of protection of the present application; the orientation words "inner" and "outer" refer to the inner and outer of the contour of each component itself.

[0023] As Figures 1-5 The reinforcing assembly for paper packaging box comprises a reinforcing frame arranged at the top and bottom openings of the packaging box, the reinforcing frame comprises two long rods 1 arranged in parallel, a plurality of short rods 11 are fixedly connected between the two long rods, and the middle part of the short rod is fixed by a connecting rod 12 arranged in parallel with the long rod; the cross sections of the long rod, the short rod and the connecting rod are all square, support assemblies are arranged in the long rod, the short rod and the connecting rod, and reinforcing assemblies are arranged between the long rod and the short rod and between the short rod and the connecting rod.

[0024] In use, the reinforcing assembly, i.e. the reinforcing frame, is placed at the bottom of the packaging box, the goods are filled, the reinforcing frame is covered again, and finally the packaging box is sealed, so that the reinforcing frame can avoid the goods from directly contacting the top and bottom of the packaging box, thereby avoiding deformation and damage to the packaging box; the support assemblies in the long rod, the short rod and the connecting rod can prevent vertical deformation, thereby guaranteeing the reinforcing effect, and the reinforcing assemblies can guarantee the stability between the parts and prevent horizontal deformation. The scheme has the advantages of simple structure and good reinforcing effect
