Description

Technical Field

[0001] This utility model relates to the field of luggage handle technology, specifically a high-strength luggage handle. Background Technology

[0002] Suitcases, also known as travel cases or rolling suitcases, are boxes used to carry items when traveling, on business trips, or going to school. For working professionals who frequently travel for work or people who love to travel, suitcases are an indispensable tool when traveling. Dragging suitcases through security checks, catching high-speed trains, and entering and leaving client companies are all common scenarios.

[0003] The luggage handle is an important component of a rolling suitcase. It is installed on the suitcase and features a retractable design at the top, making it easier for people to use the suitcase. However, the handle is a vulnerable part of the suitcase and is often damaged due to frequent use and external impacts, such as breakage, jamming, or inability to extend or retract. Most luggage handles are fixed inside the suitcase, making it inconvenient to replace the handle separately. As a result, the entire suitcase may be discarded due to a damaged handle, which not only affects normal use but also increases operating costs. Therefore, there is a need for a high-strength luggage handle. Utility Model Content
