AI Technical Summary

Technical Problem

Existing suitcases lack convenient hidden storage structures and long-distance extension limit functions, resulting in unstable placement of items, and the auxiliary structures occupy space and affect the ease of dragging when not in use.

Method used

This suitcase is made of self-reinforced polypropylene composite material and features a hidden magnetic bracket and an extendable support rod. When not in use, the bracket is magnetically stored inside the pull rod, and when needed, it can be rotated out to form a storage platform. The support rod automatically unfolds through a two-stage spring structure to provide stable support.

Benefits of technology

It improves the space utilization efficiency and practicality of the suitcase, with adjustable support area, stable placement of items, and no extra space occupation when storing, meeting diverse storage needs.

Abstract

This utility model relates to the field of luggage technology, and in particular to a polypropylene self-reinforced composite material suitcase, including a suitcase body and pull rods. The suitcase body is provided with two pull rods, and a first storage slot is provided on one side of each pull rod. A first rotating shaft is provided at the lower end of the first storage slot, and a bracket is fixedly connected to the first rotating shaft. An iron sheet is fixedly connected to the inner wall of the first storage slot, and a magnetic suction plate is fixedly connected to the outer wall of one side of the bracket. This device utilizes a hidden magnetic suction bracket structure and a two-stage spring-driven limiting device to achieve efficient space storage and reliable item limiting, solving the problems of existing devices lacking convenient hidden storage structures and long-distance extension limiting functions.
