Description

Technical Field

[0001] The utility model relates to the technical field of cartons, in particular to a self-locking glue-free airplane box carton. Background Art

[0002] The airplane box, named for its airplane-like shape when unfolded, is a branch of carton. Airplane boxes are usually used for express packaging and delivery. They are mainly made of corrugated paper, and there are also versions made of hollow boards. This box has a sturdy structure and is suitable for protecting the safety of internal items during transportation. Airplane boxes are widely used in the field of e-commerce logistics and are often used to load and transport goods such as clothing. The airplane box includes a box body and an upper cover. One side of the upper cover is connected to the box body, and the other side is connected to a gusset plate. There are tongues on both sides of the gusset plate. When the upper cover is buckled, the tongues on both sides of the gusset plate are inserted into the slots on both sides of the box body. When packing the airplane box, use the sealing tape to wrap around the seam between the upper cover and the box body of the airplane box, and in order to prevent the firmness of the airplane box, it will be wrapped several more times, but this will increase the packaging cost and the packaging process will be more time-consuming and labor-intensive.

[0020] See the attached drawings. The self-locking glue-free airplane box carton of this embodiment comprises a front side panel 1, a bottom panel 2, a rear side panel 3, a cover panel 4 and a front buckle panel 5 which are connected in sequence longitudinally. The bottom panel 2 is provided with folded outer panels 6 and inner buckle panels 7 on both sides. A second bayonet 61 is provided at the fold between the outer panel 6 and the bottom panel 2. A second clamping block 71 is provided on the outer side of the inner buckle panel 7. The inner buckle panel 7 is folded inwardly, and the second clamping block 71 is clamped and fixed with the second opening 61.

[0021] The front buckle plate 5 is provided with an inserting tongue 51 on both sides, and a first clamping block 52 matching with the clamping slot is provided at the front end of the inserting tongue 51, the width of the connecting part of the first clamping block 52 and the inserting tongue 51 is consistent with the width of the front end of the first clamping block 52, the front end width W1 of the first clamping block 52 is smaller than the rear end width W2, and the first clamping block 52 has inclined edges on both sides, that is, the rear ends of the first clamping block are expanded outward to form blocking ends 53. In order to facilitate the subsequent smooth insertion of the first clamping block into the first clamping port, the first clamping block can be flattened a little in advance.

[0022] The front side plate 1 is provided with front tongue plates 11 on both sides, and the rear side plate 3 is provided with rear tongue plates 31 on both sides. The front tongue plates 11 and the rear tongue plates 31 can be inserted between the outer side plate 6 and the inner buckle plate 7, and a slot is formed between the front tongue plates 11 and the outer side plate 6. A foldable insert plate 32 is provided on the outer side of the rear tongue plate 31, and the insert plate 32 of the rear tongue plate 31 is folded outward, that is, the insert plate 32 is attached to the inner wall of the outer side plate 6. A first bayonet 33 is provided at the fold between the insert plate 32 and the rear tongue plate 31.

[0023] The first bayonet 33 includes an elongated opening 34 and notches 35 on both sides of the opening. The length L1 of the elongated opening 34 is consistent with the width W1 of the front end of the first card block, and the width of the opening is consistent with the thickness of the front end of the first card block. The length of the notches on both sides of the opening and the total length L2 of the elongated opening are consistent with the width W2 of the blocking ends 53 on both sides of the first card block. The tongue is inserted into the slot, and the first card block 52 is fixedly engaged with the first bayonet 33.

[0024] The first bayonet 33 has an opening only in the middle and cutouts on both sides, so that when the first clamping block 52 is inserted into the first bayonet 33, the first clamping block 52 can prop open the cutout 35 through the inclined edges, so that the first clamping block 52 can smoothly pass through the first bayonet 33. After passing through, the propping force on the cutout disappears, and the cutout will be closed due to the characteristics of the cardboard, and the blocking end 53 of the first clamping block abuts against the cutout 35, so that the first clamping block 52 is engaged and fixed with the first bayonet 33, so that the inserting tongues 51 on both sides of the front buckle plate 5 are fixed, and the front buckle plate 5 is also fixed.

[0025] When assembling the aircraft box:

[0026] 1) Fold the front side plate 1 and the rear side plate 3 so that they stand upright on the front and rear sides of the bottom plate 2;

[0027] 2) Folding the front tongue plate 11 and the rear tongue plate 31 toward each other, and folding the insert plate 32 outward, so that the first latch 33 on the fold between the insert plate 32 and the rear tongue plate 31 faces the front side;

[0028] 3) Fold the outer plate 6 and the inner plate 7, the outer plate 6 is placed outside the front tongue plate 11 and the rear tongue plate 31, the inner plate 7 covers the inner side of the two, and the second clamping block 71 on the inner plate 7 is inserted into the second opening 61 of the bottom plate, and the inner plate 7 presses the front tongue plate 11 and the rear tongue plate 31;

[0029] 4) Fold the cover plate 4, fold the ears on both sides of the cover plate 4, and insert them into the inner side of the inner buckle plate 7;

[0030] 5) Fold the front gusset plate 5, and insert the tongues 51 on both sides of the front gusset plate 5 into the slots between the front tongue plate 11 and the outer plate 6. At this time, the first clamping block 52 at the front end of the tongue 51 will first hit the first clamping hole 33, and then the tongue 51 is pushed inward with force, so that the first clamping block 52 opens the cut 35. After all of them pass through the first clamping hole 33, the slender opening 34 of the first clamping hole is stuck at the connection between the first clamping block 52 and the tongue 51, and the cut 35 is closed. At this time, if you want to open the airplane box, you can only pull the front gusset plate violently to damage the first clamping block. This also allows the consignee to determine whether the packaging box has been opened by someone, to ensure that the internal products are not lost or replaced, etc., to avoid economic losses.

[0031] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
