DETAILED DESCRIPTION

[0025] The utility model discloses a telescopic draw-bar box, below combining preferred embodiment (example 1), referring to the Figures 1 to 8 , the specific implementation of the utility model is further described.

[0026] Referring to the Figures 1 to 8 , Figures 1 to 4 respectively show the telescopic draw-bar box in different visual angle of folding state, Figures 5 to 8 respectively show the telescopic draw-bar box in different visual angle of unfolding state.

[0027] Example 1.

[0028] Preferably, the telescopic draw-bar box comprises a hard front shell 100, a hard rear shell 200, a soft shell 300 and at least one webbing structure 400, wherein:

[0029] The rigid front shell 100 and the rigid rear shell 200 are interlocked. One side of the soft shell 300 is fixedly connected to the inner surface of the rigid front shell 100, and the other side of the soft shell 300 is fixedly connected to the inner surface of the rigid rear shell 200. This allows the soft shell 300 to switch between a folded state and an unfolded state under external force. When the soft shell 300 is in the folded state, it is folded and stored in the cavity (not shown in the figure) formed by the rigid front shell 100 and the rigid rear shell 200, thus saving space. When the soft shell 300 is in the unfolded state, the rigid front shell 100 and the rigid rear shell 200 are pulled apart laterally, creating a gap between them. This allows the unfolded soft shell 300 to hold more items, thereby increasing the overall storage capacity of the telescopic suitcase.

[0030] The webbing structure 400 includes a front shell fixing part 410, a rear shell fixing part 420, and a webbing 430. The front shell fixing part 410 is fixedly connected to the outer surface of the rigid front shell 100, and the rear shell fixing part 420 is fixedly connected to the outer surface of the rigid rear shell 200. One end of the webbing 430 is connected to the front shell fixing part 410, and the other end of the webbing 430 is connected to the rear shell fixing part 420. This allows the webbing structure 400 to be stretched or relaxed under external force. When the soft shell 300 is in a folded state, the webbing 430 is naturally relaxed. When the soft shell 300 is in an unfolded state, the webbing 430 is stretched, and the more items the soft shell 300 contains, the more obvious the stretching of the webbing 430 becomes. The more obvious the stretching of the webbing 430, the stronger the overall structural strength of the telescopic suitcase in the unfolded state.

[0031] Preferably, there are four webbing structures 400, with two webbing structures 400 distributed on each side of the telescopic suitcase.

One end of the webbing 430 is integrally formed with the front shell fabric body 412, and the other end of the webbing 430 is integrally formed with the rear shell fabric body 422. When the webbing structure 400 is stretched by an external force, the front shell fabric body 412, the rear shell fabric body 422, and the webbing 430 help to distribute the force.

[0033] The front U-shaped body 411 is preferably made of metal, and the rear U-shaped body 421 is preferably made of metal; thus, the webbing structure 400 is a combination of metal parts and fabric.

[0034] The front shell U-shaped body 411 is preferably a fabric, and the rear shell U-shaped body 421 is preferably a fabric; so that the whole of the belt structure 400 is integrally formed by the fabric.
