AI Technical Summary

Technical Problem

Existing impact-resistant packaging boxes, when using a combination of support springs and pads, cause the box volume to expand and the device to be fixed to the outer wall of the box, making them unusable for recycling.

Method used

The protective frame is nested in the center of the packaging box, the side guards are connected to the protective frame, the inner support block forms the bottom support, the support rod engages with the slot, the swing top block engages with the through slot, and the buffer pad and the inclined tension spring achieve protection on both sides. The support spring lifts the swing top block to engage, forming a detachable connection.

Benefits of technology

It provides effective impact protection without increasing the size of the packaging box, and is removable and reusable, making it suitable for forklift transportation.

Abstract

This utility model discloses a packaging box with impact protection, including a packaging box with a protective frame nested in the center and side guards installed at both ends. A fixing block is provided inside the protective frame, with a slot on the fixing block. A swing shaft is installed on the fixing block, and a swing top block is nested on the swing shaft. A cover block is installed on the fixing block, with a through groove on the cover block. A support spring is provided below the swing top block. By nesting the protective frame in the center of the packaging box and then connecting it with the side guards, the inner support block provides support for the bottom of the packaging box. When pushed inward, the support rod engages in the slot, and the swing top block is lifted to engage in the through groove, forming a connection. This achieves protection for both sides of the packaging box. Compared to the traditional combination of support springs and pads, the volume is close to the initial size of the packaging box, without increasing the area. When not in use, it can be removed and reused for other packaging boxes, forming a recycling system.
