DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a pass box. [Prior Art] Liquid helium a , , , , , , 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 Due to the cost of production, the process and module segment process generally adopts a division of labor in different regions. After the LCD panel is manufactured, it usually needs to be transported to an area with low labor cost for assembly. The pass box of the prior art for loading the liquid crystal panel is as shown in FIG. 1 . The pass box ίο includes a body 12, an upper cover 13 and a pallet u. The upper cover 13 is provided with guide sheets 14 ′ on both sides thereof. The guide bow u 14 is engaged with the body 12. The body 12 is disposed on the pallet to facilitate handling. ^ The volume of the through box 10 is designed according to the size of the liquid crystal panel to be loaded. When different sizes of panels are to be loaded, corresponding boxes of different volumes are required, which greatly increases the production cost. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a pass box capable of changing the volume. The field I box includes a body including four fixed side walls 2 and preferably side walls. The four fixed side walls respectively correspond to the four folded side walls, and the through box adjusts the volume by flipping the four folded side walls. 200819357 Compared with the prior art, when loading liquid crystal panels of different sizes, the height of the pass box is changed correspondingly, so that the pass box can be most effectively utilized. When the load of the transport is constant, the efficiency of the transport pass can be increased, thereby saving transportation costs. [Embodiment] Please refer to FIG. 2, which is a schematic structural view of a pass box of the present invention. The through box 20 includes a body 22, an upper cover 25 and a pallet 21, and the body 22 includes four fixed side walls 221 and four folded side walls 222. The fixed side wall 221 is made of aluminum, and the four fixed side walls 221 are provided with an iron bracket 225 at the intersection. The four folded side walls 222 are made of a magnetic material, and each of the folded side walls 222 includes two folding surfaces 223. The folding surfaces 223 are connected by a hinge 224. The folding surface 223 adjacent to the fixed side wall 221 is also fixed by a hinge 224. The side walls 221 are connected, and each of the folded faces 223 is rotatable about the hinge 224. The upper cover 25 is made of iron. The four corners of the upper cover 25 are provided with a guiding piece 251. The upper cover 25 is engaged with the body 22 by the guiding piece 251. The body 22 is disposed on the pallet 21, and the body 22 is detachable from the pallet 21 or may be fixed together. When it is necessary to load goods such as a liquid crystal panel, the liquid crystal panels are firstly put together, and the liquid crystal panels are separated by a buffer material, and then packaged with a buffer material such as Expanded Polypropylene (EPP) material. The packaged liquid crystal panel is slowly placed in the through box 20, and finally the upper cover 25 is covered to be transported. When it is required to load liquid crystal panels of different sizes, in order to achieve the most economical transportation, it is necessary to change the volume of the through box 20. Each folded face 223 is folded down about the hinge 200819357 chain 224, as shown in FIG. Since each of the folded faces 223 is made of a magnetic material, each of the folded faces 223 can strongly adsorb the iron bracket 225, thereby being brought into close contact with the respective fixed side walls 221. Due to the presence of the hinge 224, there is a certain gap between each of the folded faces 223 near the hinge 224 and each of the fixed side walls 221, and the width of the gap is exactly equal to the thickness of the guide piece 251 by using a suitable hinge 224, so the upper cover 25 The body 22 can be fastened as shown in FIG. According to actual needs, a different number of folding faces 223 can be folded down to obtain a pass box of different heights. At this time, the process of loading the cargo box 20 is consistent with the foregoing method, and details are not described herein again. For example, how the through box 20 is loaded with different sizes of liquid crystal panels, please refer to FIG. 5, FIG. 6, FIG. 7, and FIG. 8. FIG. 5 is a plan view of the seventeen inch liquid crystal panel of the present invention. Fig. 6 is a cross-sectional view showing a 17-inch liquid crystal panel mounted in the box of the present invention. Fig. 7 is a plan view showing a twenty-two-inch liquid crystal panel of the present invention. Figure 8 is a cross-sectional view showing a twenty-two 液晶 liquid crystal panel of the present invention. When a seventeen-inch liquid crystal panel needs to be loaded, the pass-through 20-layer can accommodate up to nineteen liquid crystal panels 30, and can be installed in two layers, that is, a total of thirty-eight liquid crystal panels 30 can be accommodated. The height of the pallet 21 of the through box 20 is 160 mm, the height of the fixed side wall 221 is 480 mm, and the height of the folded piece 223 is 120 mm. In this example, two folded sheets 223 are used, and the height of the upper cover 25 is 30 mm. After the thirty-eighth liquid crystal panel is loaded and the upper cover 25 is fastened, the total height of the through box 20 is 910 mm. When it is necessary to load a twenty-two liquid crystal panel, a pass box 20 having a height as shown in Fig. 8 is used. The through box 20 can hold up to eighteen LCD panels 200819357 40 and can only be installed one layer. Step #杯# ,..〇c , , , After loading the eighteen liquid crystal panels 40 and fastening the crucible, the total height of the through box 20 is 07〇mm. It can be seen from the above examples that the liquid crystal panel is not used. With the previous = get the most effective pick-up # When the load of the transport is fixed, the efficiency of the phase can be transported, thus saving transportation costs. The folding surface 223 of each folding side wall 222 can also be one layer, three sounds, two layers, two layers, and the other side walls 221 and the four side walls 222 can also be respectively used by / His method corresponds to the activity connection.
