Description

Technical Field

[0001] The utility model relates to the technical field of corrugated cartons, and particularly relates to a flame-retardant corrugated carton. Background Art

[0002] Corrugated cardboard is made into corrugated cartons through die-cutting, indentation, stapling or gluing. Corrugated cartons are the most widely used packaging products, and their usage has always been the first among various packaging products, including calcium plastic corrugated cartons. For more than half a century, corrugated cartons have gradually replaced transportation packaging containers such as wooden boxes with their superior performance and good processing performance, becoming the main force in transportation packaging. In addition to protecting goods, facilitating storage and transportation, they also play a role in beautifying and promoting goods. Corrugated cartons are green environmental protection products, which are beneficial to environmental protection and facilitate loading, unloading and transportation.

[0003] Corrugated cartons are usually used for packaging and transporting objects. When there is a gap between the box body and the object during transportation, and the side of the box body is squeezed or impacted by an external force, the side of the box body is prone to deform inward. After the side of the box body deforms, the support performance of the box body decreases, which easily causes damage to the objects inside the box. Content of the Utility Model

[0004] The purpose of the utility model is to provide a flame-retardant corrugated carton in view of the defects and deficiencies of the prior art.

[0005] To achieve the above purpose, the following technical solutions are adopted in the utility model: a flame-retardant corrugated carton, including a box body, a receiving cavity formed on the box body for placing an object, further including a support frame plate that is liftably arranged in the receiving cavity on the box body, at least four support rods arranged on the box body in the receiving cavity, at least four longitudinal openings longitudinally formed on the support frame plate for clearance fit with the support rods, and a limiting plate arranged on the end face of each support rod away from the box body for limiting the support frame plate. Four support plates are arranged on the box body in a rectangular and equidistant manner. The positions of the longitudinal openings correspond to those of the support rods. The diameter of the limiting plate is larger than the diameter of the longitudinal openings.

[0006] Further improvement is that: the support frame plate is made of steel plate or acrylic plate or wood board.

[0007] Further improvement is that: a flexible buffer plate is arranged on the end face of the limiting plate close to the support frame plate.

[0008] Further improvement is that: the flexible buffer plate is a sponge plate or a foam board.

[0009] Further improvements are as follows: There are a total of eight support rods, and the eight support rods are arranged equidistantly in a rectangle on the box body within the accommodation cavity. There are a total of eight longitudinal openings, and the eight longitudinal openings are opened equidistantly in a rectangle on the support frame plate.

[0010] Further improvements are as follows: A flame-retardant and fire-proof coating is provided on the outer side of the box body.

[0011] Further improvements are as follows: The flame-retardant and fire-proof coating is a fire-retardant paint layer or a decorative fire-proof paint layer.

[0012] Further improvements are as follows: A connecting bottom plate is detachably arranged on the support frame plate, and an avoidance opening for the support rod and the limiting plate to pass through is opened on the connecting bottom plate.

[0013] After adopting the above technical solutions, the beneficial effects of the present utility model are as follows: Align the longitudinal openings on the support frame plate with the support rods, and place the support frame plate into the accommodation cavity on the box body. The support frame plate can improve the support of the box body, and reduce the deformation of the side surface of the box body towards the inside of the box when the outer side of the box body is extruded or impacted by an external force. The limiting plate restricts the position of the support frame plate, and can further prevent the support frame plate from deforming towards the inside of the box when the side surface of the box body is extruded or impacted by an external force, thereby improving the support effect of the support frame plate on the box body, and thus not easily causing damage to the objects inside the box.

[0014] Further effect: The flexible buffer plate can reduce the damage caused by the support frame plate hitting the limiting plate when the box body is impacted by an external force and the support frame plate deforms towards the inside of the box.

[0015] Further effect: When the support frame plate is placed into the accommodation cavity, the connecting bottom plate is also placed down along the inner wall of the support frame plate, and the support rod and the limiting plate pass through the avoidance opening, so as to contact the bottom surface of the box body. When an object is placed in the accommodation cavity, it can support the object and improve the bottom stability of the support frame plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] A flame-retardant and fire-proof coating 8 is arranged on the outer side of the box body 1.

[0029] The flame-retardant and fire-proof coating 8 is a fire-proof and flame-retardant paint layer or a finishing fire-proof paint layer. A fire-proof and flame-retardant paint is a special functional paint whose coating can delay the combustion of combustible materials such as wood. It mainly should have the function of preventing the base material from being ignited by the flame, that is, the anti-combustion function, the function of preventing the base material from burning or retarding the development of combustion, that is, the flame-retardant function, and isolating the base material from the heat source to avoid temperature rise. A finishing fire-proof paint is an oil-based fire-proof paint. After being coated on the surface of the base material, it can not only play a certain decorative role due to its smooth coating film and rich colors, but also be an intumescent oil-based fire-proof paint that can play a fire protection role for the coated base material and prevent the spread of the flame when a fire occurs.

[0030] A connecting bottom plate 9 is detachably arranged on the support frame plate 3, and an avoidance opening 10 for the support rod 4 and the limiting plate 6 to pass through is formed on the connecting bottom plate 9.
