Description

Technical Field

[0001] The utility model relates to the technical field of luggage, and in particular to an anti-deformation luggage pull rod. Background Art

[0002] Luggage trolleys are a common accessory, primarily designed to facilitate the transport of suitcases or bags. Pulling the handle allows the bag to be moved, reducing the burden of carrying. Trolleys typically consist of a nylon or leather handle, a handle attached to the side of the bag, and wheels mounted on the bottom. Trolley designs vary, with single and double handles being the most common. Double handles offer greater stability, while single handles, while compact, are less stable. Trolley materials also vary, with all-aluminum being the ideal choice for their lightness and strength. Trolley mounting locations also vary. Internal handles offer a neat appearance but take up space, while external handles save space but appear untidy. Trolleys operate on a retractable mechanism, typically consisting of a tube and an internal piston. This mechanism can be unlocked by pressing a button or a wrench, allowing the handle to extend and retract freely. Trolley cases are not only easy to carry and use but also provide increased stability and durability.

[0003] The application number is CN202021585410.4, which discloses a foldable luggage trolley that is not easily deformed, including a pull block, both sides of the bottom of the pull block are fixedly connected to a first pull rod, the bottom of the front of the first pull rod is movably connected to a second pull rod through a hinge, the bottom of the second pull rod is fixedly connected to a mounting seat, and the surfaces of the first pull rod and the second pull rod are both provided with an anti-deformation layer. The utility model achieves the advantages of improving the anti-deformation and corrosion resistance of the luggage trolley by arranging an anti-deformation layer, a steel layer, an iron layer, an aluminum alloy layer, a corrosion-resistant layer, an epoxy resin paint layer, a phenolic resin paint layer and an inorganic zinc-rich paint layer to cooperate with each other, so that the luggage trolley can effectively improve the strength of the luggage trolley when in use, prevent the luggage trolley from deformation, and at the same time effectively improve the corrosion resistance of the luggage trolley, prevent the luggage trolley from corrosion damage, and extend the service life of the luggage trolley.

[0004] Although the above-mentioned utility model achieves the advantages of improving the anti-deformation and corrosion resistance of the luggage trolley by setting the anti-deformation layer, steel layer, iron layer, aluminum alloy layer, corrosion-resistant layer, epoxy resin coating layer, phenolic resin paint layer and inorganic zinc-rich paint layer to cooperate with each other, so that the luggage trolley can effectively improve the strength of the luggage trolley when in use, prevent the luggage trolley from deformation, and effectively improve the corrosion resistance of the luggage trolley, prevent the luggage trolley from corrosion damage, and extend the service life of the luggage trolley, but there is a disadvantage that when the device is used, the comfortable height of the trolley is different for users of different heights, and the common trolley adjustment is usually a one-section or two-section adjustment method, so that the height adjustment is limited and fixed, so that the trolley that cannot be adjusted to multiple levels of height has certain disadvantages in terms of comfort when in use.
