The elastic engaging component 330 is preferably made of the same material as the elongated body 31 (); however, in different embodiments, the elastic engaging component 33G may also be different from the elongated body 31〇. Or it can be made by reading the f. In the embodiment shown in Fig. 3, the 'elastic engaging element is an elongated structure; the connecting portion 331 is located in the middle portion of the elongated structure, and the engaging portion is located at the opposite ends of the elongated structure. . In the implementation shown in Fig. 3, the engaging portion 333 is located at the first position, and the engaging portion 333 protrudes beyond the side surface 311 of the elongated body (10). In this embodiment, since the miscellaneous engaging member 33() is in the _ split, there is a miscellaneous engaging portion 201226281 reading 330. The elongated strip body 31 has two corresponding side states and the end faces 313 ′. The two ends of the end faces 313 are respectively connected to the end edges of the side faces 311. ^ Located on the long side of the strip-shaped body and distributed along the long strip = 〇 extension direction. The end face 313 abuts against the short side of the elongated body (10) and is preferably perpendicular to the side 311. Both ends of the elongated body 310 respectively abut against the two side walls (10) of the casing 2 (8). Since the wire (10) is a rectangle, the _ _ _ _ _ _ _, 5 is formed in the rectangle formed by the bottom plate 210. Preferably, the top of the cushioning support device is adapted to provide a positioning function when the t-plate or its skein or the item to be transported is loaded. In the preferred embodiment, the "buffering" is made of expanded polypropylene (Epp) material, but can also be made using other materials. 333. Therefore, the two engaging portions 333 respectively protrude from the opposite side faces of the main body 3ι 201226281. The _3G system spans the elongated body 310 3 . However, in different implementations, the engaging element (10) may also have only the early engaging portion 333, and therefore only protrudes beyond the single side 3ΐ. In the case of the eight-section s, the elastic position energy due to the external force is accumulated in the elasticity. Therefore, the engaging portion 333 can be positioned in two positions without any external force. When combined with the case 200, the engaging portion 333 can be bent to the second position, and the engaging portion is twisted and contracted to the side of the elongated body 3 (1) as shown in the figure, and because the elastic engaging member 33 is Deformation and accumulation of elastic potential energy. In this embodiment, the engaging portion 333 is bent down to the underside of the elongated body 310, but is also maintained in the plane in which the side 311 of the elongated body 310 extends; in other words, the card s 4 333 is in the test. After the second position, it is located on the same side of the side surface 11 as the elongated body 3 (1). In the preferred embodiment, the engaging portion 333 is folded to the second position by an external force, and the engaging portion 333 is maintained in the second position by the external force. When the external force is removed, the engaging portion 333 is fully or partially reset to the first position by the accumulated elastic position. As shown in Fig. 5, the side wall 230 of the casing 2 has a plurality of lugs 231 and ear holes 233. The ear hole 233 and the lug 231 are mutually corresponding; in other words, the ear hole 233 is formed corresponding to the lug 231. As shown in FIG. 5, the ear hole 233 is formed by the lug 231. In this embodiment, the lug 231 is located at a position where the side wall 23 is connected to the bottom plate 210, that is, at a side of the bottom plate 210. The ear hole 233 is surrounded by the lug 231, the side wall 230, and the bottom plate 210. In the preferred embodiment, the lug 231 can be formed by cutting parallel and spaced cutting lines 25 于 in the direction of the edge of the straight bottom plate 210 on the side wall 230 and the bottom plate 210, as shown in FIG. 6; A portion of the middle of the cutting line 250 is ejected to form a lug 231. However, in various embodiments, the lug 231 can also be adhered, stapled, or otherwise formed on the sidewall 230 or the bottom plate 210. Further, the shape of the lug 23] is not limited to the rectangular shape shown in Figs. 5 and 6, but may be thin or other shapes. As shown in Figs. 7A and 7B, the lugs 231 are formed on the side walls 230 in such a manner as to be disposed. When the engaging portion 333 of the elastic engaging member 33 is bent to the second position, the end surface 313 of the elongated body 310 and the engaging portion 333 can extend between the adjacent lugs 231. In this embodiment, the spacing between the adjacent lugs 231 is equal to or similar to the width of the end surface 313 of the elongated body 31, so that the adjacent lugs 231 can also provide the effect of positioning the elongated body 31〇. As shown in FIG. 8A and FIG. 8B, when g removes the external force of the bending engagement portion, the engaging portion 333 is spring-returned to the first position by the elastic position, and extends into the ear hole to be engaged with the lug 2M. The positioning buffer support device 3 is placed in the casing 2〇〇. In this embodiment, since the lug 231 is formed at the connection position of the side wall 230 and the bottom plate 210, the elastic engaging element 330 is also disposed at the bottom edge of the end surface 313 of the elongated body 31 to fit the lug. The position of 231 corresponds. As shown in FIG. 9, the side wall 230 and the bottom plate 210 are formed with perforations 235 at positions corresponding to the lugs 231. In this embodiment, since the lug 231 is cut and lifted from the side wall 230 and the bottom plate 210, residual perforations 235 are formed in the side wall 23 and the bottom plate 21A. When the elastic engaging member 330 extends into the ear hole 233 and engages with the lug 231, the elastic engaging member 33 can shield the through hole 235 to reduce the chance of moisture, dust or other foreign matter entering the casing 2. In addition, the end face 313 of the elongated body 310 may also help to shield the perforations 235. In the embodiment of the present invention, the working hole 237 is selectively formed with the working hole 237 and the through hole 235; the working hole 237 is preferably located at one side of the through hole 235 toward the adjacent lug 231. . By the arrangement of the working holes 237, the user can extend the working hole 237 by hand or tool to adjust the position of the elastic engaging member 330 or assist the engaging portion 333 to spring back to the first position. However, in various embodiments, the position of the resilient snap element 33 can also be adjusted directly via the perforations 235 without providing the working aperture 237'. When the elastic engaging member 330 extends into the ear hole 235 and engages with the lug 231, the elastic engaging member 330 can also shield the working hole 237 to reduce the chance of moisture, dust or other foreign matter entering the casing 2. In the embodiment shown in FIG., the end surface 313 of the buffer support device 300 is formed with a recess 350 recessed in the end surface 313. The groove 350 spans the end surface 313 and connects the opposite side faces 311. The connecting portion 331 of the elastic engaging member 33 is adhesively attached to the recess 350, and a part of the elastic engaging member 33 () is also fitted into the recess 350, and only the engaging portion 333 protrudes from the recess 35. outer. When the engaging portion 333E is folded in the second position, the connecting portion of the elastic engaging member 33 is still adhered to the inside of the recess 350. In different embodiments, the connection portion of the elastic snap-on branch 33 can also be integrally connected to the groove 35〇; for example, the long-form (4) g and the elastic card component 330 can be formed on the Wei material. , the above-mentioned one-piece molding connection state can be produced. In this embodiment, since the lug 231 is disposed on the side wall and the bottom end of the casing 2, the groove 35〇 is also disposed adjacent to the bottom edge of the end surface of the elongated body 31. However, in different embodiments, as shown in Fig. u, a concave = 5 length portion of the body end surface 313 may also be formed. In the example of the embodiment shown in FIG. 11, the connecting portion 331 of the elastic engaging element 33 is also bonded to the inside of 201226281; however, in different implementations, the elastic card s element 330 may be formed in a concave manner. The groove is 35 inches. Figure 12 shows another embodiment of the package structure. In this embodiment, the lug 231 of the case is disposed at a middle portion of the side wall 230, and the ear hole 233 is formed directly on the lug 231. The lug 231 is directly cut from the side wall coffee and then bent into the inside of the box body, and then the shape of the ear hole 233 is first turned out. As shown in Fig. 12, the lugs 231 are preferably paired and parallel to each other and formed to be bent toward each other. The buffer wrap device 300 extends into the space between the lugs 231 and is extended by the resilient snap members 33 to engage the lugs 23i. As shown in FIG. 12, when combined with the case 200, the engaging portion 333 can be bent to the second position 'to cause the engaging portion 333 to ride parallel to the extending direction of the elongated body 31〇 and protrude from the end surface 313 outer. In the second position, the engaging portion 333 is in the plane in which the side surface 311 of the elongated body 31 extends; that is, the engaging portion and the elongated body 310 are located on the same side of the side surface 311. As shown in FIG. 13, when the external force of the bending engagement portion 333 is removed, the engaging portion 333 is spring-returned to the first position by the elastic position energy field, and protrudes into the ear hole 233 to be engaged with the lug 231. Hehe. Figure 14 is another embodiment of a baggage structure. In this embodiment, the lugs 231 of the casing (10) are disposed at the corner positions and are respectively located at the connection positions of the side walls 23 and the bottom plate 21 and the connection positions of the side walls 230 and the adjacent side walls 230. The engaging portions 333 of the elastic engaging members 330 respectively protrude from the adjacent side faces 311 of the elongated body 31〇 to respectively correspond to the lugs 231. When the combination is performed, the engaging portions 333 can be respectively bent to the second position to retract the side walls 23〇 and 23〇, and then the engaging portion 333 is rebounded back to the first position to extend into the ear hole 233 and the lug. 231 Card 201226281 The present invention has been described by the above-described related embodiments, but the above embodiments are merely examples for implementing the present invention.
