DETAILED DESCRIPTION

[0028] In order to further illustrate the present invention, the present invention will be described in detail below through some embodiments.

[0029] like Figure 1The utility model is shown in a schematic diagram of a self-locking aircraft box cutting piece. In the figure, the upper cover folding surface 12 is connected to the upper cover side folding surface 21 on both sides, and the upper cover side folding surface 21 is provided with a lock buckle 211. The end of the upper cover folding surface 12 close to the lock buckle is connected to the plug plate, with a point close to the midpoint of the end of the upper cover side folding surface 21 close to the plug plate as one end, and the upper cover side folding surface 21 away from a point about one-third of the other end of the upper cover folding surface 12 as the other end. The fold with the two points as endpoints divides the upper cover side folding surface into a triangular structure. On this basis, the triangular structure needs to be cut off at the end close to the plug plate 11, and the area of ​​the lock buckle 211 structure cut out at this time is smaller than the triangular structure.

[0030] In some embodiments, the triangular structure is an isosceles right triangle, the height of the cropped trapezoid is 0.1 to 0.1125 of the side length of the triangular structure, and the area of ​​the lock 211 structure is between 78.765625% and 81% of the area of ​​the triangular structure.

[0031] The upper cover folding surface 12 is connected to a tailgate folding surface 13 at one end away from the plugboard. Both sides of the tailgate folding surface 13 are connected to tailgate side folding surfaces 22 . A fold is provided between the tailgate side folding surface 22 and the tailgate folding surface 13 .

[0032] The end of the rear baffle folding surface 13 away from the upper cover folding surface 12 is connected to the lower bottom surface folding surface 14, and a fold is provided between the lower bottom surface folding surface 14 and the rear baffle folding surface 13. The two sides of the lower bottom surface folding surface 14 are connected to the first lower bottom surface side folding surface 23, and the first lower bottom surface side folding surface 23 is provided with an easy-opening structure 231. The two outer sides of the first lower bottom surface folding surface 23 are connected to the second lower bottom surface folding surface 24, and a double fold is provided between the first lower bottom surface folding surface 23 and the second lower bottom surface folding surface 24. The second lower bottom surface side folding surface is provided with a rectangular notch at the end close to the front baffle 15.

[0033] The end of the lower bottom folding surface 14 away from the rear baffle 13 is connected to the front baffle folding surface 15, a fold is provided between the lower bottom folding surface 14 and the front baffle folding surface 15, and the two sides of the front baffle folding surface 15 are connected to the front baffle side folding surfaces 25, and the front baffle side folding surfaces 25 are provided with lock holes.

[0034] In some embodiments, the shape of the easy-to-open structure 231 is composed of a semicircle and a rectangle, the diameter of the semicircle is equal to the length of one side of the rectangle, and one side of the semicircle diameter is connected to one side of the rectangle, forming the shape of the easy-to-open structure 231, and the two outer sides of the relative width of the lock hole 251 correspond to the two outer sides of the relative width of the rectangle. The area of ​​the easy-to-open structure 231 is smaller than the area of ​​the lock hole structure rectangle, and the overall length and width of the lock hole 251 rectangle are greater than the overall length and width of the easy-to-open structure 231.

[0035] The overall length and width of the rectangular lock hole 251 are greater than the overall length and width of the easy-open structure 231. When the aircraft box is folded and formed, since the overall length and width of the rectangular lock hole 251 are greater than the overall length and width of the easy-open structure 231, the easy-open structure 231 can enter the lock hole 251 and press against the lock buckle 211 structure, thereby opening the aircraft lock. In addition, relevant personnel can use the easy-open structure 231 to determine whether the aircraft box has been opened, thereby playing an anti-theft role.

[0036] like Figure 2 The utility model is shown in the folding forming diagram of a self-locking aircraft box cut piece involved in the present invention. The front baffle folding surface 15 is folded 90 degrees upward relative to the lower bottom folding surface 14 along the fold provided between the lower bottom folding surface 14 and the front baffle folding surface 15. The front baffle side folding surface 25 is folded 90 degrees inward relative to the lower bottom folding surface 14 along the fold provided between the front baffle folding surface 15 and the front baffle side folding surface 25. The rear baffle folding surface 13 is folded 90 degrees along the fold provided between the rear baffle folding surface 13 and the lower bottom folding surface 14. Some folds are connected with the upper cover fold surface 12, the insert plate 11, the tailgate side fold surface 22 and the upper cover side fold surface 21 to be folded upward 90° relative to the lower bottom fold surface 14, and the first lower bottom side fold surface 23 is connected with the second lower bottom side fold surface 24 to be folded upward 90° relative to the lower bottom fold surface 14 along the fold between the lower bottom fold surface 14 and the first lower bottom side fold surface 23. One side of the arc of the easy-to-open structure 231 is tangent to one side of the rectangle of the lock hole 251 after folding.

[0037] In this way, the easy-opening structure 231 is tangent to one side of the lock hole 251. In this way, when opening the aircraft box, it can interact with the lock buckle 211 structure through the lock hole 251, so that the relevant operator only needs to press the easy-opening structure 231 on the outside when opening the aircraft box; when opening for the first time, the easy-opening structure 231 will not deviate to the inside of the box body. After multiple openings, the easy-opening structure 231 will deviate to the inside of the box body. Therefore, during the assembly process of the aircraft box, the easy-opening structure 231 will be squeezed outward by the lock buckle 211 structure until the plane of the easy-opening structure is parallel to the plane of the side folded surface of the first bottom surface, which makes it more convenient for the operator to open the aircraft box.

[0038] like Figure 3 The utility model is shown in a folding diagram of a self-locking aircraft box cut piece involved in the present invention. The second lower bottom side fold surface 24 is provided along a double fold between the first lower bottom side fold surface 23 and the second lower bottom side fold surface 24. The double folds are folded 90° respectively, so that the inserting tongue 241 on the second lower bottom side fold surface is inserted into the socket 141 on both sides of the lower bottom fold surface 14, and one side of the rectangular notch provided on the second lower bottom side fold surface 24 is aligned with one side of the arc of the easy-open structure 231 and one side of the rectangle of the lock hole 251.

[0039] The main purpose of this operation is to first connect the second lower bottom side folding surface 24 with the sockets 141 provided on both sides of the lower bottom folding surface 14, and through this operation, the folded airplane box body structure can be made more stable, so that the airplane box is not easy to automatically disperse during transportation of the packaging box, because in the folding process, the front baffle 15 has a tendency to fold outward, the front baffle side folding surface 25 has a tendency to fold outward relative to the width direction of the box body, the rear baffle 13 has a tendency to fold outward, and the rear baffle side folding surface 22 has a tendency to fold outward relative to the width direction of the box body, and the second lower bottom side folding surface 24 is connected to the sockets provided on both sides of the lower bottom folding surface 14 through the provided tongues 241. 141 is connected, first of all, the position of the first lower bottom side folding surface is fixed, and the positions of the front baffle side folding surface 25 and the rear baffle side folding surface 22 are fixed between the first lower bottom side folding surface 23 and the second lower bottom side folding surface 24, and this operation is performed on both sides in the width direction of the box body, and because the positions of the front baffle side folding surfaces 25 connected on both sides of the front baffle folding surface 15 are fixed, the position of the front baffle folding surface 15 is fixed, and because the rear baffle side folding surfaces 22 connected on both sides of the rear baffle folding surface 13 are fixed, the position of the rear baffle folding surface is fixed, so through the design of the tongue 241 of the second lower bottom side folding surface 24 and the socket 141 of the lower bottom folding surface 14, the structure of the box body of the aircraft box is more stable when it is packaged.

[0040] like Figures 4 to 6 The utility model shown is a folding and forming diagram of a self-locking aircraft box cutting piece. After the above-mentioned folding process is completed, the lock buckle 211 structure needs to be folded toward the outside of the box body relative to the upper cover side folding surface 21 along the crease provided between the lock buckle 211 structure and the upper cover side folding surface 21, so that the lock buckle 211 structure is in contact with the plane where the upper cover side folding surface 21 is located. After the operation is completed, the upper cover side folding surface 21 is folded inward 90° relative to the upper cover folding surface 12 along the crease provided between the upper cover folding surface 12 and the upper cover side folding surface 21, and the insert plate 11 is folded inward 90° relative to the upper cover folding surface 12 along the crease provided between the insert plate 11 and the upper cover folding surface 12.

[0041] like Figures 7 to 9 The diagram of the folding and forming of the self-locking aircraft box pieces involved in the utility model is shown. On the basis of the completion of the above-mentioned folding operation, the upper cover folding surface 12 is connected with the upper cover side folding surface 21 along the fold provided between the upper cover folding surface 12 and the rear baffle 13. The lock 211 structure provided on the upper cover side folding surface 21 and the inserting plate 11 are folded 90° inwardly toward the box body relative to the rear baffle folding surface 13, so that the aircraft box is folded and formed.

[0042] During the folding process, the structure of the airplane box is relatively small, and since the airplane box has a self-locking function when folded, the assembly of the airplane box is more convenient than the folding process of ordinary airplane boxes on the market. Ordinary airplane boxes require the side folding surface of the inserting plate 11 to be inserted into the gap formed by several folding surfaces in order to maintain the locking function of the box body, making the box body difficult to open.

[0043] During the folding process, the lock buckle 211 structure is automatically clamped between the second lower bottom side folding surface 24 and the front baffle side folding surface 25. In this way, if the relevant operator wants to open the aircraft box through the upper cover folding surface, the lock buckle 211 structure will be clamped between the second lower bottom side folding surface 24 and the front baffle side folding surface 25, making it difficult to open the aircraft box. The box body structure needs to be destroyed to open the aircraft box, which makes the aircraft box safer. Since its easy-opening structure 231 is hidden in the first lower bottom side folding surface 23, the easy-opening structure can be hidden to a certain extent. Moreover, if the box body of the aircraft box is to be taken out, the relevant operator only needs to press the easy-opening structure 231 on both sides of the box in the width direction to squeeze the lock buckle 211 out from between the second lower bottom side folding surface 24 and the front baffle side folding surface 25. At this time, the upper cover folding surface 12 of the aircraft box is opened, allowing the relevant operator to take out the objects in the box body more conveniently.

[0044] After the above operation, if the relevant operator wants to close the aircraft box, he only needs to close the upper cover folding surface 12, because during this operation, the lock buckle 211 structure can be automatically clamped between the second lower bottom side folding surface 24 and the front baffle side folding surface 25. Since the lock buckle 211 structure is clamped between the second lower bottom side folding surface 24 and the front baffle folding surface 25, the easy-opening structure 231 is squeezed by the lock buckle 211 to the plane where the first lower bottom side folding surface 23 is located. In this way, after the aircraft box is opened, its box body can also be closed, so that the aircraft box can be reused many times, achieving a green and environmentally friendly effect to a certain extent.

[0045] The present utility model has explained its purpose, technical solutions and beneficial effects in depth through specific embodiments, but these embodiments are only used as examples to demonstrate the application of the invention and do not constitute a limitation on the scope of protection of the present utility model.
