Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a shock absorber frame used for electrical equipment and the like, and in particular, can be easily assembled without using an adhesive or a jig, and can be easily unassembled after use and compact. The present invention relates to a shock absorber frame such as cardboard electrical equipment that can be folded and disposed of.
[0002]
[Prior art]
A packaging method is widely used in which a cardboard box frame is laid on the bottom of the cardboard box and electric devices are placed on the cardboard frame. The buffer frame in this case is generally one in which both ends of the corrugated cardboard are bent in a cylindrical shape and provided with a mounting portion. Since both ends are not fixed, the assembled state is not fixed, and electrical equipment is mounted. When placing, the buffer frame must be pressed by hand, and workability is not good.
In addition, there is a type where both ends are bonded and fixed, but the work of bonding is required, and when discarding the frame body after use, the problem that it can not be compacted unless the bonded and fixed part is peeled off was there.
