[0002] With the improvement of people's living standards, the travel demand is increasing day by day. As an essential item for travel, the design of the suitcase is constantly improving and developing.
[0003] Currently, the thickness of the front box of the suitcases on the market is usually thin, the storage space of the front box is small, the pull rod is relatively thick and the gap between the pull rod and the inner wall of the rear box is large, the handle groove and the wheel groove are relatively deep, resulting in the space inside the box being squeezed again, the capacity of the box is insufficient, and the zipper between the front box and the rear box is usually a single-track zipper, which is difficult to pull up when storing more items, and is easy to burst and damage. All these factors limit the storage capacity and durability of the suitcase and affect the use experience. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a large-capacity suitcase with strong storage capacity and strong durability for the above problems existing in the prior art.
[0005] The purpose of the utility model can be realized by the following technical solutions:
[0006] A large-capacity suitcase, including a box body, a telescopic pull rod and universal wheels. The telescopic pull rod is arranged on the box body, and the number of the universal wheels is four. The four universal wheels are arranged in a rectangular array at the bottom of the box body. It is characterized in that the box body is composed of a front box and a rear box, the front box and the rear box are connected by a double-track zipper, the telescopic pull rod extends into the upper end of the rear box and is fixedly connected with the lower end of the rear box, the part of the telescopic pull rod located inside the rear box is adjacent to the inner wall of the rear box, the outer end of the telescopic pull rod has a handle, the handle has a recessed hanging groove, the upper end of the rear box has a recessed shallow handle groove and the handle can be embedded at the shallow handle groove, and the bottoms of the front box and the rear box have recessed shallow wheel grooves and the universal wheels can be connected at the shallow wheel grooves.
[0007] This large-capacity suitcase is composed of a front box and a rear box, and the two are connected by a double-track zipper. The double-track zipper has higher strength and is not easy to damage, ensuring that the opening and closing of the box body are smoother and more durable; the telescopic pull rod is thinner, the gap between the telescopic pull rod and the inner wall of the rear box is small, and the recessed depths of the shallow handle groove and the shallow wheel groove are relatively shallow.

The perspective mesh sandwich layer allows users to quickly view the items placed therein, improving the use efficiency.
[0014] In the above-mentioned large-capacity luggage case, both the front box body and the rear box body are made of thickened PC material.
[0015] The thickened PC material is light in weight and has high strength and toughness, which can provide good protection and at the same time reduce the overall weight of the luggage case, thereby improving the durability and portability of the luggage case.
[0016] In the above-mentioned large-capacity luggage case, a bearing is provided inside the universal wheel.
[0017] The setting of the bearing inside the universal wheel makes the luggage case move more smoothly. It can be easily pushed even when it contains a large number of items, improving the moving performance.
[0018] In the above-mentioned large-capacity luggage case, the telescopic pull rod is made of thickened aviation aluminum.
[0019] The thickened aviation aluminum has the advantages of light weight and high strength, ensuring that the relatively thin telescopic pull rod can still maintain stability and durability after being used multiple times for a long time, while reducing the overall weight of the luggage case.
[0020] In the above-mentioned large-capacity luggage case, the thickness of the front box body is 2 / 3 - 1 times that of the rear box body.
[0021] The thicknesses of both the front box body and the rear box body are thicker than those of traditional luggage cases, thus effectively increasing the internal space of the box body, having a larger capacity, and being able to accommodate more items.
[0022] Compared with the prior art, the components in this large-capacity luggage case occupy less internal space of the box body, and the thicknesses of the front box body and the rear box body are thickened, further increasing the capacity, thereby effectively improving the storage capacity of the luggage case; the double-track zipper improves the zipper strength and avoids the problem that the zipper is likely to burst under heavy load. The box body made of thickened PC material enhances the structural strength and durability. The bearing is provided inside the universal wheel to ensure that the box body moves more smoothly. These structures all improve the durability of the luggage case; the setting of the hanging groove on the handle facilitates carrying items such as handbags, reduces the travel burden, and improves the usability; the settings of the partition layer, the dry-wet separation sandwich layer, and the perspective grid sandwich layer enable items to be stored separately, avoid mutual contamination, are convenient for searching, and improve the practicality of the luggage case.
