Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box technology, specifically a puncture-resistant corrugated cardboard box. Background Technology

[0002] Corrugated boxes are made of corrugated cardboard with a hollow structure. There are many types of corrugated boxes, which are widely used in various industries, especially with the increasing demand in the e-commerce and logistics sectors. Quality inspection of corrugated boxes is crucial, as performance indicators such as compressive strength and bursting strength affect their reliability during transportation.

[0003] Currently, corrugated cardboard boxes are easily punctured by sharp objects during use and transportation, failing to adequately protect the contents. Furthermore, the openings of corrugated cardboard boxes are prone to opening under stress, causing contents to fall out and potentially damage them. Therefore, we have proposed a puncture-resistant corrugated cardboard box to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a puncture-resistant corrugated cardboard box to solve the problem mentioned in the background art that corrugated cardboard boxes on the market are easily punctured by sharp objects during use and transportation, and the ends of the corrugated cardboard boxes are easily broken under force, causing the contents to fall out.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a puncture-resistant corrugated cardboard box, comprising a corrugated cardboard box shell, wherein a through hole is provided on the side of the corrugated cardboard box shell, a fixing cylinder passes through the interior of the through hole, and a fixing ring is threaded to the end of the fixing cylinder;

[0006] The fixed cylinder is internally threaded with a mounting post. One end of the mounting post, which extends into the corrugated cardboard box shell, is fitted with a wire mesh plate. The other end of the mounting post is fitted with a limit rod, and a fixing strap is sleeved on the limit rod.

[0007] Preferably, the corrugated carton shell includes a corrugated core layer, a flame-retardant rubber layer, and a protective mesh layer. The flame-retardant rubber layer is distributed between two sets of corrugated core layers, and the corrugated core layer is distributed between the flame-retardant rubber layer and the protective mesh layer.

[0008] Preferably, the protective mesh layer includes nylon thread one and nylon thread two, and the protective mesh layer is a mesh surface formed by the crisscrossing arrangement of nylon thread one and nylon thread two.

[0009] Preferably, the outer diameter of the fixing ring is larger than the inner diameter of the through hole, and the fixing ring clamps and fixes the fixing cylinder to the side of the corrugated cardboard box shell.

[0010] Preferably, the interior of the mounting column is hollow and filled with a desiccant.

[0011] Preferably, the fixing straps surround the corrugated cardboard box shell, and the ends of the fixing straps are respectively fastened to symmetrically distributed limiting rods.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) The puncture-resistant corrugated cardboard box uses a flame-retardant rubber layer to prevent puncture, providing additional support to the cardboard box and increasing the strength of the box. The mesh formed by the cross-layout of nylon thread one and nylon thread two further increases the strength of the cardboard box, preventing the corrugated cardboard box from being punctured and providing good protection for the contents.

[0014] (2) The puncture-resistant corrugated cardboard box is reinforced and tightened by fixing straps to prevent the corrugated cardboard box from being forced open. The hollow interior of the mounting column is filled with desiccant to keep the inside of the corrugated cardboard box dry and prevent the objects inside the corrugated cardboard box from getting damp.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6 The present invention provides the following technical solution: a puncture-resistant corrugated cardboard box, including a corrugated cardboard box shell 1, a through hole 2 on the side of the corrugated cardboard box shell 1, a fixing cylinder 3 passing through the through hole 2, and a fixing ring 4 threadedly connected to the end of the fixing cylinder 3;

[0024] Furthermore, the outer diameter of the fixing ring 4 is larger than the inner diameter of the through hole 2. The fixing ring 4 clamps and fixes the fixing cylinder 3 to the side of the corrugated cardboard box shell 1, so that the fixing ring 4 blocks the through hole 2 and enables the fixing cylinder 3 to be easily disassembled and assembled.

[0025] The internal thread of the fixed cylinder 3 is connected to the mounting post 5. One end of the mounting post 5, which extends into the corrugated cardboard box shell 1, is equipped with a wire plate 7. The other end of the mounting post 5 is equipped with a limit rod 6, and a fixing strap 8 is fitted on the limit rod 6.

[0026] Furthermore, the interior of the mounting column 5 is hollow and filled with a desiccant, which helps to keep the inside of the corrugated cardboard box dry.

[0027] Furthermore, the fixing strap 8 surrounds the corrugated cardboard box shell 1, and the ends of the fixing strap 8 are respectively fastened to the symmetrically distributed limiting rods 6. The fixing strap 8 is used to reinforce and bind the corrugated cardboard box to prevent it from falling apart.

[0028] Furthermore, the corrugated cardboard box shell 1 includes a corrugated core layer 101, a flame-retardant rubber layer 102, and a protective mesh layer 103. The flame-retardant rubber layer 102 is distributed between two sets of corrugated core layers 101, and the corrugated core layer 101 is distributed between the flame-retardant rubber layer 102 and the protective mesh layer 103.

[0029] Furthermore, the protective mesh layer 103 includes nylon thread one 1031 and nylon thread two 1032. The protective mesh layer 103 is a mesh surface formed by the crisscrossing arrangement of nylon thread one 1031 and nylon thread two 1032, which increases the strength of the cardboard box and prevents the corrugated cardboard box from being punctured.

[0030] Specifically, when using this puncture-resistant corrugated cardboard box, the fixing cylinder 3 is passed through the through hole 2, and the fixing ring 4 is threaded to the end of the fixing cylinder 3. The fixing cylinder 3 is then fixed to the corrugated cardboard box shell 1. Then, the mounting post 5 can be threaded into the fixing cylinder 3. One end of the mounting post 5 with the wire mesh 7 extends into the corrugated cardboard box shell 1. The inside of the mounting post 5 is filled with desiccant to keep the inside of the corrugated cardboard box dry. One end of the fixing strap 8 is fitted onto the limiting rod 6. The fixing strap 8 is wrapped around the corrugated cardboard box shell 1 once, so that the other end of the fixing strap 8 is fitted onto the limiting rod 6 at the adjacent position. The fixing strap 8 is used to reinforce and tighten the port of the corrugated cardboard box to prevent the port of the corrugated cardboard box from being forced open.

[0031] The corrugated cardboard box shell 1 includes a corrugated core layer 101, a flame-retardant rubber layer 102, and a protective mesh layer 103. The flame-retardant rubber layer 102 can prevent punctures, provide additional support to the cardboard box, and increase the strength of the box. The protective mesh layer 103 is a mesh formed by nylon thread 1031 and nylon thread 1032 arranged in a crisscross pattern, which further increases the strength of the cardboard box, prevents the corrugated cardboard box from being punctured, and provides good protection for the contents. The contents not described in detail in this specification are prior art known to those skilled in the art.
