Abstract
Description
Technical Field
[0001] This utility model relates to the field of cushioning pad technology, and in particular to a compression-resistant cushioning pad for vacuum packaging of seasoned beef slices. Background Technology
[0002] A cushioning pad is a material used to reduce or absorb external impacts, pressure, or vibrations, typically used to protect items from damage during transport, storage, handling, or use. It prevents breakage or deformation by converting external impact forces into slow, dissipated energy, thus reducing the stress on the item.
[0003] In existing technologies, cushioning pads are discarded by users after use and cannot be effectively reused. This makes it impossible to achieve sustainable resource recycling, resulting in a large amount of resource waste. Furthermore, because the material is difficult to degrade, it causes long-term pollution to the ecosystem. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a vacuum packaging anti-compression cushioning pad for seasoned beef slices.
[0005] This utility model is achieved using the following technical solution: a vacuum packaging anti-crushing cushion for seasoned beef slices, comprising a cardboard box, a cushioning pad slidably connected to the inner wall of the cardboard box, a sealing groove formed on the inner wall of the cushioning pad, an inflation groove formed inside the cushioning pad, a fixing plate fixedly connected to the outer wall of the inflation groove, a connecting rod slidably connected inside the fixing plate, a push plate fixedly connected to the outer wall of the connecting rod, a spring slidably connected to the outer wall of the connecting rod, a limit plate fixedly connected to the end of the connecting rod away from the spring, a rubber plug fixedly connected to the end of the connecting rod away from the limit plate, an inflation nozzle fixedly connected to the outer wall of the inflation groove, and a protective cap threadedly connected to the inflation nozzle.
[0006] As a further improvement to the above solution, the rubber plug is slidably connected to the outer wall of the sealing groove.
[0007] As a further improvement to the above solution, several cushioning pads are provided, and the cushioning pads are evenly distributed on the inner wall of the carton; several protective covers are provided, and the protective covers are evenly distributed on the inner wall of the carton.
[0008] Through the above technical solution, this utility model uses an airbag-like cushioning pad to provide soft protection for the packaging bag, reducing the stress on the packaging bag and thus preventing damage or deformation, protecting the integrity and quality of the packaging bag. Simultaneously, a sealing groove and an inflation groove are respectively formed inside the cushioning pad. A fixing plate is fixed to the outer wall of the inflation groove, and a sliding connecting rod slides inside the fixing plate. The connecting rod is fixed to a push plate, a limiting plate, and a rubber plug. A sliding spring slides on the outer wall of the connecting rod, pushing the limiting plate so that the rubber plug contacts the outer wall of the sealing groove, thereby preventing gas leakage from inside the cushioning pad. Furthermore, when reuse is required, personnel can detach the protective cap from the inflation nozzle by threading it together with the inflation nozzle, allowing air to be blown inside, thus achieving reuse, resource recycling, and reducing environmental pollution.
[0009] As a further improvement to the above solution, a lower EPE foam board is fixedly connected to the bottom of the inner wall of the carton, and an upper EPE foam board is slidably connected to the inner wall of the carton.
[0010] As a further improvement to the above solution, the inner wall of the carton is slidably connected with EVA foam, and several EVA foams are provided, which are evenly distributed on the inner wall of the carton.
[0011] As a further improvement to the above solution, the top of the EVA foam is provided with a placement groove, and a plurality of placement grooves are provided, which are evenly distributed on the top of the EVA foam.
[0012] Through the above technical solutions, EVA foam is soft and has a cushioning effect, which can effectively absorb impact and protect the packaging bag from being squeezed and damaged.
[0013] As a further improvement to the above solution, a honeycomb paperboard is fixedly connected to the inner wall of the carton, and a plurality of honeycomb paperboards are provided, which are evenly arranged on the inner surface of the carton.
[0014] The above technical solution involves fixing honeycomb paperboard to the inner wall of the carton. The honeycomb paperboard has excellent cushioning performance and can effectively absorb impact and vibration.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention uses an airbag-like cushioning pad to provide soft protection for the packaging bag, reducing the stress on the bag and preventing damage or deformation, thus protecting the integrity and quality of the packaging bag. The cushioning pad has a sealing groove and an inflation groove inside. A fixing plate is fixed to the outer wall of the inflation groove, and a sliding connecting rod slides inside the fixing plate. The connecting rod is fixed to a push plate, a limiting plate, and a rubber plug. A sliding spring slides on the outer wall of the connecting rod, pushing the limiting plate so that the rubber plug contacts the outer wall of the sealing groove, thus preventing gas leakage from the cushioning pad. When reuse is required, the protective cap is threaded onto the inflation nozzle, allowing air to be inflated inside, enabling reuse, resource recycling, and reducing environmental pollution.
[0017] This invention utilizes sliding EVA foam along the inner wall of a cardboard box. EVA foam is soft and has a cushioning effect, effectively absorbing impact and protecting the packaging bag from being squeezed and damaged. An EPE foam board is fixed to the bottom of the inner wall of the cardboard box. The EPE foam board is lightweight, soft, and highly elastic, effectively mitigating external impact and supporting the cardboard box to prevent deformation and squeezing of the internal packaging bag.
