Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of luggage boxes, and in particular to a device for preventing luggage inside the luggage box from being damaged. Background Art
[0002] As we all know, luggage is a container used to store and transport personal belongings, typically made of hard or soft materials and offering some degree of protection. It is designed with one or more zippers or locks for easy opening and closing, and often features interior dividers or pockets to help organize belongings. Luggage often has wheels and handles on the exterior for easy carrying and dragging, and is often used for travel, business trips, or long-distance relocations. Depending on its purpose and capacity, luggage comes in different sizes and styles, including carry-on luggage, suitcases, and checked luggage.
[0003] However, traditional suitcases often lack adequate internal securing features. Once fully loaded, items can easily shift and jolt. This is especially true when the suitcase is tilted, inverted, or subjected to sudden acceleration. Items can collide and rub against each other. For example, clothing can become snagged on hard objects, causing damage. Cosmetic bottles can collide and break, staining other luggage. Precision equipment like electronics can even be damaged by collisions. Therefore, technological improvements are urgently needed. Utility Model Content

[0019] Through the above technical solution, the threaded rod can be easily driven to rotate by the knob.
[0020] Furthermore, both sides of the inner wall of the storage tank are provided with limiting grooves, and both sides of the outer wall of the limiting cushion cylinder are fixedly connected with limiting blocks, and the limiting blocks are respectively slidably connected inside the limiting grooves;
[0021] Through the above technical solution, the limiting blocks are respectively slidably connected inside the limiting grooves, which facilitates limiting the threaded sleeve.
[0022] The utility model has the following beneficial effects:
[0023] 1. This utility model proposes a device for preventing luggage from being damaged inside a suitcase. Compared to existing suitcases, when this suitcase is in use, turning a knob drives a threaded rod, which in turn drives a threaded sleeve, which then cooperates with a limit telescopic rod and a limit spring to limit the position. This can drive the sponge pad to continuously approach the placement slot, thereby fitting the luggage in the placement slot, ensuring that the luggage will not shake inside the suitcase and cause damage.
[0024] 2. This utility model proposes a device for preventing luggage damage inside a suitcase. Compared to existing suitcases, this device, when in use, uses a return spring to compress or rebound according to the size of the luggage, thereby fitting luggage of different sizes in the placement slot, preventing damage caused by shaking and displacement of items within the suitcase, and having higher practical performance.
