Technical Field

[0001] This utility model belongs to the field of padding technology, specifically relating to a honeycomb cardboard padding for household appliance packaging. Background Technology

[0002] Currently, the padding used in the packaging of home appliances is mostly made of common plastic foam. This material is lightweight and low-cost, but its overall pressure resistance, impact resistance and cushioning performance in actual use are not ideal and cannot protect the corresponding home appliances well. In addition, some full-coverage paddings consisting of upper and lower parts are usually only connected by abutting to facilitate disassembly, resulting in poor full-coverage stability during actual transportation, which needs to be improved. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a honeycomb cardboard liner for home appliance packaging, which can form multiple layers of protection and has better stability, so as to solve the above problems.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a honeycomb cardboard liner for household appliance packaging, comprising an upper liner and a lower liner. Both the upper and lower liners consist of an inner honeycomb cardboard layer, a foam aluminum plate layer, and an outer honeycomb cardboard layer from the inside out. The inner surface of the inner honeycomb cardboard layer of the upper liner is adapted to the upper surface of the household appliance, and the inner surface of the inner honeycomb cardboard layer of the lower liner is adapted to the lower surface of the household appliance. The foam aluminum plate layer of the upper liner has several internally threaded through holes vertically formed, and the top of the foam aluminum plate layer of the lower liner has several internally threaded blind holes. The upper liner and the lower liner abut against each other. The internally threaded through holes and the internally threaded blind holes correspond one-to-one, and the corresponding internally threaded through holes and internally threaded blind holes are screwed together with the same fixing screw.

[0005] Preferably, a groove is provided at the position corresponding to the head of the fixing screw, and the head of the fixing screw is located in the corresponding groove with its top surface lower than the top surface of the groove.

[0006] Preferably, a plurality of rotating rods are fixed on the periphery of the head of the fixing screw.

[0007] Preferably, the fixing screw is a nylon screw.

[0008] Preferably, the inner honeycomb paperboard layer and the foamed aluminum board layer, as well as the foamed aluminum board layer and the outer honeycomb paperboard layer, are bonded together with epoxy resin adhesive.

[0009] Preferably, the outer surface of the outer honeycomb paperboard layer is provided with an epoxy resin coating.

[0010] The beneficial effects of this utility model are as follows: In use, the full-coverage packaging pad formed by the upper and lower pads can comprehensively wrap and protect the corresponding household appliances. Furthermore, the bolted connection between the upper and lower pads offers better stability and is more practical compared to the original simple abutment connection. Simultaneously, both the upper and lower pads are multi-layered pad structures composed of an inner honeycomb cardboard layer, a foam aluminum board layer, and an outer honeycomb cardboard layer. Both the honeycomb cardboard and foam aluminum materials possess lightweight, high strength, and excellent cushioning, shock absorption, and impact resistance properties, resulting in superior compression resistance, impact resistance, and cushioning effects for the entire packaging pad. This provides multiple layers of effective protection for the corresponding household appliances, making it more conducive to the packaging and transportation of household appliances and more practical.

Detailed Implementation

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0015] like Figure 1 and 2 As shown, a honeycomb cardboard liner for home appliance packaging includes an upper liner 1 and a lower liner 2. Both the upper liner 1 and the lower liner 2 include an inner honeycomb cardboard layer 3, a foam aluminum plate layer 4, and an outer honeycomb cardboard layer 5 from the inside out. The inner surface of the inner honeycomb cardboard layer 3 of the upper liner 1 is adapted to the upper surface of the home appliance, and the inner surface of the inner honeycomb cardboard layer 3 of the lower liner 2 is adapted to the lower surface of the home appliance. The foam aluminum plate layer 4 of the upper liner 1 has several internally threaded through holes 6 vertically opened, and the top of the foam aluminum plate layer 4 of the lower liner 2 has several internally threaded blind holes 7. The upper liner 1 and the lower liner 2 abut against each other. The internally threaded through holes 6 and the internally threaded blind holes 7 correspond one-to-one, and the corresponding internally threaded through holes 6 and internally threaded blind holes 7 are screwed together with the same fixing screw 8.

[0016] In use, the full-coverage packaging pad formed by the upper pad 1 and the lower pad 2 can provide comprehensive protection for the corresponding home appliances. The bolted connection between the upper pad 1 and the lower pad 2 offers better stability and is more practical compared to the original simple abutment connection. Furthermore, both the upper pad 1 and the lower pad 2 are multi-layered pad structures composed of an inner honeycomb cardboard layer 3, a foam aluminum board layer 4, and an outer honeycomb cardboard layer 5. Honeycomb cardboard and foam aluminum are readily available materials, both of which possess lightweight, high strength, and excellent cushioning, shock absorption, and impact resistance properties. This results in superior compression resistance, impact resistance, and cushioning effects for the entire packaging pad, providing multiple layers of effective protection for the corresponding home appliances, making it more convenient for packaging and transporting appliances, and thus more practical.

[0017] In this embodiment, a groove 9 is provided at the position corresponding to the head of the fixing screw 8. The head of the fixing screw 8 is located in the corresponding groove 9 and its top surface is lower than the top surface of the groove 9 so as not to affect the outer packaging.

[0018] In this embodiment, several rotating rods 10 are fixed on the periphery of the head of the fixing screw 8 for hand-tightening operation, which facilitates disassembly and assembly.

[0019] In this embodiment, the fixing screw 8 is a nylon screw, which is lightweight, easy to install, and low in cost. Compared with metal screws, it is more suitable for packaging pads, which are relatively disposable applications.

[0020] In this embodiment, the inner honeycomb paperboard layer 3 and the foam aluminum board layer 4, as well as the foam aluminum board layer 4 and the outer honeycomb paperboard layer 5, are bonded together with epoxy resin adhesive layer 11. This reduces the risk of deformation of the bonding surface, ensures the stability of the connection between the corresponding boards, and has a significant lightweight effect. It can also further enhance the overall waterproof, pressure-resistant, and corrosion-resistant properties of the packaging liner, resulting in better protection.

[0021] In this embodiment, the outer surface of the outer honeycomb cardboard layer 5 is provided with an epoxy resin coating 12. Epoxy resin is an existing material. This coating has high strength and wear resistance, excellent adhesion and corrosion resistance, waterproof and high temperature resistance and other properties, which can further enhance the overall waterproof, pressure resistance and corrosion resistance of the packaging liner, resulting in better protection, longer service life and greater practicality.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
