Detailed ways

The present utility model will be further described in detail below in conjunction with the accompanying drawings, which are to explain rather than limit the present utility model.

As shown in Figures 1-4, a portable travel case with adjustable accommodation space includes a base 1, an upper cover 2 and a folding support plate 3 for adjusting the volume of the travel case. The middle of the folding support plate 3 is horizontally provided with at least one strip Bending line 4, the folding support plate 3 is folded to the inside or outside of the box along the bending line 4 to reduce or expand the volume of the suitcase.

Four side walls of the suitcase are provided with a folding support plate 3 , and the two ends of the four folding support plates 3 are connected end to end to form a closed structure, which is located between the base 1 and the upper cover 2 .

The folding supporting plate 3 includes an upper supporting plate, a connecting plate and a lower supporting plate which are sequentially connected from top to bottom. A bending line 4 is arranged at the connection between the upper supporting plate and the connecting plate, and a folding line 4 is arranged at the connection between the connecting plate and the supporting plate. Bending line 4, the upper support plate and the upper cover 2 are hinged through a hinge, the hinge is installed on the inner side of the upper cover, the lower support plate and the base 1 are hinged through a hinge, and the hinge is installed on the inner side of the base.

The bending line 4 is a horizontal groove provided on the support plate.

Horizontal reinforcing ribs 5 are symmetrically arranged on the upper and lower sides of the bending line 4 .

It can be seen from the above structure that when the volume of the suitcase is in the maximum state, the folding support plate is in a vertical state. When the volume of the suitcase needs to be reduced, the upper cover is pressed down, the upper end of the upper support plate and the lower support plate are The lower ends of the upper and lower support plates are all rotated to the inside of the box around the hinges connected to them, and the other ends of the upper and lower support plates are folded along the bending line. U-shaped structure, when the upper cover is in contact with the base, the suitcase is folded to the smallest volume. When the volume of the suitcase needs to be increased, the upper cover can be pulled upward to increase the volume of the suitcase.

As shown in Figure 5-7, in order to fix the size of the adjusted suitcase, a support rod is also arranged between the base and the upper cover. One end of the support rod is connected to the base, and the other end is connected to the upper cover.

The folding support plate may also be composed of a plurality of continuous support plates, the plurality of support plates are continuously folded in a Z-shape, and the folding directions of two adjacent bending lines are opposite.

The upper support plate and the lower support plate can also be connected with the connecting plate through hinges.

At the same time, in order to improve the convenience of the suitcase in the moving process and make it more labor-saving to go up the steps, a transmission device is provided on the base 1, and the transmission device includes a transmission wheel 6 and a conveyor belt 7. Two transmission wheels are arranged on the base 1 at intervals, one of which is It is arranged at the lower end of the base 1 (the lower end is the end that contacts the ground during the movement of the suitcase), and the other one is arranged at the middle of the base 1 . The conveyor belt is wound on the drive wheel, and when going up the steps, the conveyor belt contacts the step and can rotate around the drive wheel 6 from top to bottom.

The transmission device is arranged between the two pull rods of the suitcase, the pull rod is provided with a horizontal fixed shaft, the transmission wheel is sleeved on the fixed shaft, and the surface of the transmission wheel is provided with tooth grooves, the double-sided toothed conveyor belt of the transmission belt, the transmission belt and the toothed belt. The grooves are engaged with each other, and a plurality of support wheels are arranged at intervals between the two transmission wheels, and each support wheel is connected with the pull rod through a fixed shaft.

The base 1 is provided with two transmission devices, and the two transmission devices are arranged between the two pull rods at intervals. In the process of going up the steps, the person drags the lever of the suitcase to tilt the suitcase in the forward direction. At this time, the conveyor belt on the base is in contact with the steps. By moving the body upwards, the suitcase can be easily climbed up the steps. The process of going up the steps is more labor-saving, and at the same time, the whole process is more stable and the service life of the suitcase is prolonged.

The suitcase whose volume can be expanded or reduced adopts the above structure, so that the sub-board can be folded and compressed when the suitcase is vacant, thereby reducing the space occupied by the whole suitcase. When unfolded, a larger internal space can be obtained to meet the needs of use, and at the same time, it can meet the needs of larger storage space and smaller storage space when storing and carrying.
