DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] refer to Figures 1 to 10 :

[0026] The utility model patent discloses an aviation box plate splicing structure, the plate splicing structure includes a first splicing structure 10 and a second splicing structure 20, wherein the first splicing structure 10 is used for splicing side panels 2 and side panels 2, and the second splicing structure 20 is used for splicing side panels 2 and bottom panels 1, wherein the side panels 2 include wide side panels 32 and long side panels 42, preferably, the first splicing structure 10 is used for splicing wide side panels 32 and long side panels 42, and the second splicing structure 20 is used for splicing wide side panels 32 and bottom panels 1, and the first splicing structure 10 includes a long tenon convex 11 and a narrow tenon groove 12, long tenons 11 are provided on both sides of the wide side panel 32, and narrow tenons 12 are provided on both sides of the long side panel 42 at positions corresponding to the long tenons 11, the second splicing structure 20 includes a tenon 21, a mortise 22 and a self-locking tenon block 23, the bottom end of the wide side panel 32 is provided with a tenon 21 downward, the tenon 21 is provided with an inner locking groove 211, the bottom plate 1 is provided with a mortise 22 at a position corresponding to the tenon 21, and the self-locking tenon block 23 is provided with an inner locking block 24 at a position corresponding to the inner locking groove 211, and the tenon 21 can be locked by the self-locking tenon block 23 after being inserted into the mortise 22.

[0027] Specifically, the inner locking groove 211 is located on both sides of the tenon 21 and is symmetrically distributed or mirrored. The outer side of the upper end of the self-locking tenon block 23 is provided with a slow-entry slope 241, so that the self-locking tenon block 23 can be quickly inserted into the mortise 22 and locked with the inner locking groove 211. The inner side of the slow-entry slope 241 is provided with a buffer slot hole 242. The buffer slot hole 242 can be used for the self-locking tenon block 23 and the tenon 21 to be locked. The connection between the wide side plate 32 and the bottom plate 1 has a certain buffering effect to prevent the tenon 21 from being broken due to hard collision under certain conditions. At the same time, this structure can also help to make it easier to disassemble later. Specifically, the lower end of the buffer slot hole 242 is provided with a chamfered position 243, and the angle of the chamfered position 243 extends from the upper end of the outer side to the lower end of the middle, thereby forming a chamfer to facilitate better engagement with the inner locking groove 211.

[0028] Specifically, in order to prevent the self-locking tenon block 23 from falling out after being engaged with the tenon 21, an anti-falling clamping edge 221 is provided on the inner side of the mortise 22. The anti-falling clamping edge 221 can clamp the outer edge position of the self-locking tenon block 23 after being locked with the inner locking groove 211, thereby forming a stable locking mechanism.

[0029] Specifically, the narrow mortise 12 is located on both sides of the long side panel 42 and opens toward the wide side panel 32. The narrow mortise 12 has an entrance end 121 and a closed end 122, wherein the entrance end 121 is located above the narrow mortise 12 and the closed end 122 is just located at the bottom of the wide side panel 32, wherein the diameter of the entrance end 121 is larger than the diameter of the long tenon protrusion 11.

[0030] Specifically, in order to enable the long tenon 11 to form self-locking after being inserted into the narrow tenon groove 12, an annular groove 123 is provided at the lower end of the narrow tenon groove 12, and an annular convex edge 111 is provided at the position of the long tenon 11 corresponding to the annular groove 123.

[0031] Specifically, in order to distinguish it from the traditional locking structure that uses metal parts as auxiliary, here, the self-locking tenon block 23 is made of the same material as the bottom plate 1 and the wide side plate 32. In this way, the self-locking tenon block of the same material can prevent the problem of lack of bite in the later stage due to rust or reaction between different materials.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
