[0040] Embodiment 3

[0041] On the basis of embodiment 2, in addition to the structural features of the preceding embodiments, the shielding piece 4 is detachably installed on the corner piece 12 through a quick release structure.

[0042] In this embodiment of the application, the shielding piece 4 has an L-shaped cross section, the quick release structure comprises an installation groove 125, a plug plate 42, a clamping block 43 and a clamping groove 126, the installation groove 125 and the clamping groove 126 are respectively arranged on the inner lower part and the top outer side of the corner piece 12, and the plug plate 42 and the clamping block 43 are respectively arranged on the inner side wall and the inner top wall of the shielding piece 4.

[0043] As shown in Figures 4 to 5As shown, due to the adoption of the above structure, the cross section of the shielding piece 4 is L-shaped, the inner lower part of the corner piece 12 is processed with a mounting groove 125, the top outer side is processed with a clamping groove 126, the inner side wall of the shielding piece 4 is provided with a plug plate 42 matched with the mounting groove 125, the inner top wall is provided with a clamping block 43 corresponding to the clamping groove 126, when the shielding piece 4 is installed, the plug plate 42 of the shielding piece 4 is aligned with the mounting groove 125 of the corner piece 12, and is inserted in the transverse direction, so that the top surface of the plug plate 42 is in contact with the top surface of the mounting groove 125, the inner top wall of the shielding piece 4 is in contact with the top surface of the corner piece 12, until the clamping block 43 of the shielding piece 4 is aligned with the clamping groove 126 of the corner piece 12, and the clamping block 43 is clamped into the clamping groove 126 by the elastic force of the shielding piece 4 itself, so as to realize the fixed connection of the shielding piece 4 and the corner piece 12.

[0044] When the shielding piece 4 needs to be disassembled, the top outer end of the shielding piece 4 is only lifted upward, so that the clamping block 43 is separated from the clamping groove 126, and the plug plate 42 is pulled out of the mounting groove 125, so that the disassembly is quickly completed, and the maintenance and repair of the inside of the glue frame main body 1 are facilitated, and the appearance is more beautiful compared with the prior art.

[0045] Embodiment 4:

[0046] On the basis of embodiment 3, in addition to the structural features of the foregoing embodiments, the top surface of the corner piece 12 is provided with a sliding groove 121, and the inner top wall of the shielding piece 4 is provided with a convex rib 41 matched with the sliding groove 121.

[0047] In this embodiment of the application, the inner end of each sliding groove 121 is provided with a guide notch 122.

[0048] As shown in the figure, Figures 4 to 5 Due to the adoption of the above structure, when the shielding piece 4 is installed, the convex rib 41 is aligned with the guide notch 122, and then the shielding piece 4 is pushed along the length direction of the sliding groove 121 until the shielding piece 4 moves to the appropriate position, at which time the convex rib 41 is completely embedded in the sliding groove 121, so that the connection precision of the corner piece 12 and the shielding piece 4 is improved, and from the assembly point of view, due to the guiding effect of the sliding groove 121 and the convex rib 41, when the luggage is assembled in batches, the workers can more quickly and accurately position and install the shielding piece 4.

[0049] Embodiment 5:

[0050] On the basis of embodiment 2, in addition to the structural features of the foregoing embodiments, the external member is connected with the expansion port 5 through the connecting piece 7, and the mounting groove 125 is used to accommodate the inner end of the connecting piece 7.

[0051] In this embodiment of the application, the connecting piece 7 is a plug block matched with the shape of the expansion port 5 or a flexible belt 72 provided with a clamping block 71 at the tail end.

[0052] As shown in the figure, Figures 3 to 5As shown, due to the above structure, when the external member needs to be connected with the expansion port 5 through the connecting piece 7, if the connecting piece 7 is a plug block matched with the shape of the expansion port 5, first, one end of the plug block is inserted into the expansion port 5, and the inner end part of the plug block is accommodated in the mounting groove 125 of the corner piece 12, so as to realize the connection of the external member with the frame body 1.

[0053] If the connecting piece 7 is a flexible band 72 provided with a blocking block 71 at the end, the flexible band 72 is stretched through the expansion port 5 from below the mounting groove 125, and the end of the flexible band 72 is fixed by multi-layer sewing to form the blocking block 71 with a thickness greater than the opening of the expansion port 5, or the blocking block 71 is fixed at the end of the flexible band 72 by other fixing methods, so that the end blocking block 71 of the flexible band 72 is located on the inner side of the frame body 1, and the external member is fixed on the frame body 1 through the elastic deformation of the flexible band 72 and the blocking effect of the blocking block 71. The mounting groove 125 can effectively accommodate the inner end part of the flexible band 72, and ensure the stability of the appearance and the connection.

[0054] Especially, compared with the prior art, the core advantages of the binding band installation by the installation method of the present application are as follows:

[0055] Hidden connection design: In the prior art, the binding band fixing points (such as buckles, bolts) or sewing lines are exposed, which affects the neatness of the interior of the luggage (for example, the buckle seat may scratch clothes, and the bolt head needs to be additionally capped). The expansion port of the shielding piece cooperates with the flexible band (with a blocking block) in the present application, and the inner end of the connecting piece is completely accommodated in the corner piece mounting groove (embodiment 5), and only the edge of the expansion port flush with the shielding piece can be seen externally, so that the "invisibility" of the binding band connection point is realized, the interior of the luggage is kept smooth and flat, and potential damage to clothes caused by exposed structures is avoided.

[0056] Gap covering and function unification: The shielding piece is originally used to cover the gap between the edge strip and the corner piece (embodiment 1), and the setting of the expansion port makes it have the dual functions of "appearance hiding" and "functional interface", so that the independent mounting seat needs not to be additionally added as in the prior art, and the integrated design of structural reinforcement and functional expansion is realized by the same component.

[0057] Tool-free quick installation and removal: The existing buckle connection needs to press the elastic arm (which may need to be assisted by a tool), the bolt fixing relies on a screwdriver and other tools, and the sewing fixing is completely not removable. In the present application, the flexible band is connected and matched with the expansion port through the blocking block (embodiment 5), when installed, only the blocking block needs to be passed through the expansion port from inside the box and pulled tight, and the fixing can be completed by the elastic deformation of the flexible band; when removed, the blocking block can be taken out by applying force in the opposite direction, and no tool is needed throughout the process, and the single-person operation time is less than 10 seconds, which is more than 5 times higher in maintenance efficiency than the bolt fixing.

[0058] Reliability: In the prior art, the installation position of the buckle seat and the embedded stud is fixed, and the magic tape can be adjusted but has weak carrying capacity. The present scheme has high reliability (the single clamping block tensile strength is ≥80N, meeting the demand of conventional luggage strap).

[0059] III. Structure strength and reliability improvement

[0060] Load dispersion design: The strap tension is transmitted to the clamping block through the flexible belt, and then dispersed to the entire main frame of the rubber frame through the quick release structure (insert plate-installation slot, clamping block-clamping slot) of the cover and the corner piece (Example 3), avoiding the problem of "single-point stress leading to suture rupture" in the existing stitching fixation. The corner piece positioning plate supports the edge strip positioning strip (Example 7), further enhancing the strength of the connection position, making the strap fixing point and the luggage structure form a rigid whole, and the fatigue resistance under dynamic load (such as luggage transportation jolt) is improved by 30% compared with the existing buckle connection (no loosening after 50,000 vibration tests).

[0061] Waterproof and dustproof optimization: The existing bolt fixation needs to drill holes in the luggage, which may become a channel for water vapor and dust; the magic tape fitting gap is easy to accumulate dust, affecting adhesion. In the present scheme, the cover and the corner piece form a sealed sliding pair through the sliding groove-protruding rib cooperation (a dust strip can be added, and the reference Example 4 is expanded), the expanded edge and the connector are interference fit, and the cover plate hides the fastener (Example 8), the overall protection level can reach IP54, which is better than most open connection structures in the prior art.

[0062] IV. Non-destructive transformation of luggage structure

[0063] Pre-buried and drill-free: The existing bolt fixation needs to pre-bury the stud or drill holes in the side plate of the luggage, increasing the processing complexity and cost; the buckle connection relies on the mold to pre-set the buckle seat, which has poor flexibility. The present scheme utilizes the original structure of the main body of the rubber frame (corner piece, cover), realizes the installation of the strap through the standardized expanded port (preset circular, rectangular, etc. universal interface), without the need for structural modification of the main body of the luggage, and is suitable for modular upgrading of new and old luggage, especially for rapid functional iteration of customized luggage.

[0064] Example 6:

[0065] On the basis of any one of Examples 1-5, in addition to the structural features of the preceding examples, the edge strip 11 is fixed to the case shell 9 by the fastener 8, and the end portion is provided with a socket 111, and the end portion of the corner piece 12 is provided with an insertion column 123 adapted to the socket 111.

[0066] As Figures 2 to 4As shown, since the above structure is adopted, when the edge strip 11 is installed, the end of the edge strip 11 is processed with a socket 111, the end of the corner piece 12 is processed with a plug column 123 matched with the socket 111, when the edge strip 11 is spliced with the corner piece 12, the plug column 123 of the corner piece 12 is aligned with the socket 111 of the edge strip 11, and is inserted with force, so that the plug column 123 is completely embedded in the socket 111, the glue frame main body 1 assembled by the edge strip 11 and the corner piece 12 is pressed and inserted into the opening side of the box shell 9, and then the edge strip 11 and the box shell 9 are further fixed by the fastener 8, so as to ensure that the connection between the glue frame main body 1 and the box shell 9 is firm, and the splicing structure of the edge strip 11 and the corner piece 12 is stable and not easy to loosen.

[0069] In this embodiment of the application, the positioning plate 124 is provided with a glue injection hole 127.

[0070] As Figures 3 to 4 As shown, since the above structure is adopted, on the inner side wall of the edge strip 11, the positioning strip 112 is integrally formed, the positioning strip 112 is arranged along the length direction of the edge strip 11, and the positioning plate 124 is integrally formed at both ends of the corner piece 12, the upper surface of the positioning plate 124 is used to support the positioning strip 112, when the edge strip 11 is spliced with the corner piece 12, the end of the positioning strip 112 of the edge strip 11 is placed on the positioning plate 124 of the corner piece 12, and the mutual support of the positioning plate 124 and the positioning strip 112 improves the flatness of the connection position of the corner piece 12 and the edge strip 11.

[0071] In actual application, the glue is injected into the glue injection hole 127, the glue enters the gap between the positioning strip 112 and the positioning plate 124, the tightness of the connection between the positioning strip 122 and the positioning plate 124 is improved, and the high flatness of the connection position of the corner piece 12 and the edge strip 11 is further ensured.
