Description

Technical Field

[0001] This utility model relates to the field of trolley case technology, specifically to a trolley case with a reinforced structure. Background Technology

[0002] A rolling suitcase, also known as a travel case, is a box carried when traveling to store belongings; it is a type of luggage. Suitcases are typically used to store clothing, personal care items, and souvenirs needed for a trip.

[0003] During use, there are situations where users sit on the surface of the suitcase or pile items on its surface. These scenarios place new demands on the suitcase's pressure resistance and deformation resistance. Currently, there are no solutions on the market specifically designed for these usage scenarios. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide a trolley case with resistance to deformation in the height direction.

[0005] To achieve the above objectives, this utility model provides a trolley case with a reinforced structure, including a trolley case body.

[0006] The suitcase body includes a first case and a second case, which are connected by a circumferentially arranged zipper.

[0007] Also includes:

[0008] The reinforcing structure includes two tie rods and two reinforcing ribs. The tie rods are U-shaped and cover the inner periphery of the first and second housings and close them.

[0009] The pull bar has a cavity with a pre-embedded reinforcing rib inside, and the reinforcing rib is correspondingly disposed inside the pull bar. The reinforcing structure is used to increase the circumferential strength of the pull box body.

[0010] Preferably, the tie rod includes a first reinforcing tie rod and a second reinforcing tie rod, and the first reinforcing tie rod and the second reinforcing tie rod are integrally formed.

[0011] Preferably, a gap is left between the first reinforcing strip and the second reinforcing strip, and the periphery of the first box and the second box is inserted into the gap.

[0012] Preferably, the first reinforcing strip is fixedly connected to the first housing; the second reinforcing strip is fixedly connected to the second housing.

[0013] Preferably, the cavity is located at the bend of the first reinforcing strip and the second reinforcing strip.

[0014] Preferably, the reinforcing rib is made of tubular material and has a closed structure and is embedded inside the cavity.

[0015] Compared with the prior art, the technical solution proposed in this application has the following beneficial effects: by setting a reinforced structure, the overall compressive strength of the suitcase in four directions is improved. The closed-loop set of tie rods and reinforcing ribs greatly improves the stress of the suitcase, so that it will not deform under pressure or load. The pre-embedded cavity of the reinforcing rib makes the connection between the reinforcing rib and the tie rod more stable and easier to install. Attached Figure Description

[0025] The technical solutions in the embodiments of this utility model will be clearly and completely described and discussed below with reference to the accompanying drawings. Obviously, what is described here is only a part of the examples of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0026] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.
