Composite packaging base for refrigerator

Abstract

The invention discloses a composite packaging base for a refrigerator and relates to the technical field of refrigerator packaging bases. The composite packaging base comprises a packaging base body,wherein the packaging base body comprises an EPS foam plate, a super-deformed material plate and a glass fiber honeycomb plate which are arranged from top to bottom; the super-deformed material plateis fixed with the EPS foam plate and the glass fiber honeycomb plate separately through an adhesive; a plurality of first vent holes are uniformly distributed and formed in the EPS foam plate; secondvent holes which correspond to the first vent holes in a one-to-one manner are uniformly formed in the super-deformed material plate; a connecting pipe is coaxially fixed at one end of each second vent hole; and the outer walls of the connecting pipes are matched with the inner walls of the first vent holes. The composite packaging base disclosed by the invention has the beneficial effects that the deformation of the EPS foam plate and that of the glass fiber honeycomb plate are relatively small as well as the deformation of the super-deformed material plate on an intermediate layer is relatively large, so that an elastic buffer structure similar to a series spring in a mechanical structure can be formed; the elastic coefficient of the composite packaging base can be increased; and the buffer performance of the composite packaging base can be improved.

Description

technical field [0001] The invention belongs to the technical field of refrigerator packaging bases, in particular to a composite packaging base for refrigerators. Background technique [0002] At present, the packaging base for refrigerators is mainly composed of PP hollow board and EPS foam. The main disadvantages of this kind of packaging base during use are as follows: [0003] (1) Single cushioning method: The reason why the packaging base can protect the product from external impacts all comes from the compression deformation of EPS, and there is no second method other than this. [0004] (2) Poor EPS cushioning performance: After 6-10 times of drop tests, the EPS foam deforms greatly and cannot return to the state before use, which makes the EPS foam lose its original cushioning protection performance. If you continue to use it, if the product Suffering from external shocks increases the risk of failure. [0005] (3) The PP hollow board is easy to separate from the ...

Problems solved by technology

[0003] (1) Single cushioning method: The reason why the packaging base can protect the product from external shocks is all from the compression deformation of EPS. In addition, there is no second method

[0004] (2) Poor EPS cushioning performance: After 6-10 times of drop tests, the EPS foam deforms greatly and cannot return to the state before use, which makes the EPS foam lose its original cushioning protection performance. If you continue to use it, if the product Suffering from external shocks, the risk of failure increases

[0005] (3) The PP hollow board is easy to separate from the EPS, which cannot effectively protect the EPS foam, resulting in damage to the packaging base, which in turn leads to customer complaints
