Multiple lockout aircraft case

Abstract

This utility model discloses a multi-locking aircraft box, comprising a front inner support plate, a bottom plate, a rear support plate, a top plate, and a front outer support plate connected in sequence. The bottom plate has folding plate units on both sides, adapted to form locking grooves. The front inner and rear support plates each have locking plates on both sides, and each locking plate has a latching groove. During assembly, the front inner and rear support plates are folded to the same side on the bottom plate, and then each locking plate is folded inwards towards the inside of the box. At this point, the latching grooves of the two locking plates on the same side interlock, causing the front inner and rear support plates to be pulled taut together, preventing rebound. Compared with existing technologies, this utility model's aircraft box achieves higher structural stability by using latching grooves on the locking plates to lock the front inner and rear support plates together.

Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular, to a multi-locking airplane box. Background Technology

[0002] An airplane box is a foldable cardboard box, named for its resemblance to an airplane when unfolded. Its core is made of cardboard or corrugated cardboard, allowing for quick assembly and offering advantages such as lightweight, pressure resistance, and low cost. Available in three-layer and five-layer configurations, it suits various needs, including clothing and electronics. The surface can be printed with brand information and supports UV coating and lamination processes to enhance its texture, making it a cost-effective choice for e-commerce logistics and product packaging.

[0003] Existing aircraft box structures are generally as follows: Figure 1 As shown, the system includes a front inner support plate 1, a bottom plate 2, a rear support plate 3, a top plate 4, and a front outer support plate 5 connected in sequence. The bottom plate 2 has a left folding plate 17 and a right folding plate 18 on each side. A left folding plate 20 is connected to the left folding plate 17, and a right folding plate 21 is connected to the right folding plate 18. Locking plates 8 are provided on both sides of the front inner support plate 1, the front outer support plate 5, and the rear support plate 3.

[0004] During assembly, after bending the second left fold plate 20, the insert plate 22 at its end is inserted into the locking groove 19 of the base plate 2, so that a locking groove with both ends through is formed between the first left fold plate 17 and the second left fold plate 20. Then, the front inner support plate 1, the front outer support plate 5, and the rear support plate are bent in sequence and their corresponding locking plates 8 are inserted into the locking groove, thereby defining the final box body.

[0005] However, when the creases and embossing of the cardboard box are relatively inconspicuous or the corrugated strength of the cardboard box material is high, the front inner support plate 1 and the rear support plate 3 are prone to rebound, that is, the locking plates 8 of the two are prone to come out of the locking groove, which is not conducive to production and use. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multi-locking aircraft box.

[0007] The objective of this utility model is achieved through the following technical solution: A multi-locking aircraft box includes a front inner support plate, a bottom plate, a rear support plate, a top plate, and a front outer support plate connected in sequence. Both sides of the bottom plate are provided with folding plate units, which are adapted to form locking grooves. Both sides of the front inner support plate and the rear support plate are provided with locking plates, and each locking plate is provided with a buckle groove. When the box body is assembled, the buckle grooves on the two locking plates on the same side engage with each other to limit the tendency of the front inner support plate and the rear support plate to move away from each other.

[0008] Preferably, the folding plate unit includes a first folding plate and a second folding plate connected to each other. A protrusion is provided on the side of the second folding plate, and corresponding insertion holes are provided on the front inner support plate and / or the rear support plate. When the box is assembled, the protrusion is inserted into the corresponding insertion hole.

[0009] Preferably, both sides of the front outer support plate are provided with buckles for inserting into the locking groove.

[0010] Preferably, protrusions are provided on both sides of the second folding plate.

[0011] Preferably, the outer front support plate is provided with a locking buckle, and the inner front support plate is provided with a locking hole. When the box is assembled, the locking buckle is inserted into the locking hole.

[0012] Preferably, the locking buckle is connected to the side of the front outer support plate away from the top plate, and the locking hole is located at the connection between the front inner support plate and the bottom plate.

[0013] Preferably, each of the said grooves has the same shape.

[0014] The beneficial effects of this utility model are as follows: During assembly, the front inner support plate and the rear support plate are folded to the same side on the bottom plate, and then each locking plate is folded inwards towards the inside of the box. At this time, the locking grooves of the two locking plates on the same side can be interlocked, so that the front inner support plate and the rear support plate are pulled together and are less likely to rebound. Compared with the prior art, the aircraft box of this utility model achieves mutual interlocking and locking between the front inner support plate and the rear support plate by setting locking grooves on the locking plates, resulting in higher structural stability of the box body.

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] like Figure 2 , Figure 3 As shown, a multi-locking aircraft box includes a front inner support plate 1, a bottom plate 2, a rear support plate 3, a top plate 4, and a front outer support plate 5 connected in sequence. The bottom plate 2 has folding plate units 6 on both sides. After the box is assembled, the bottom plate 2 forms the bottom surface, the top plate 4 forms the top surface, and the rear support plate 3, the two front support plates (i.e., the front inner support plate 1 and the front outer support plate 5), and the two folding plate units 6 sequentially form the four sides of the box.

[0019] It can be imagined that the box body is generally composed of a main body and a lid. The main body is specifically defined by a base plate 2, a front inner support plate 1, a rear support plate 3, and two folding plate units 6. In order to ensure that the main body can stably form a recessed space for accommodating items, the folding plate units 6 are usually defined with locking grooves (not shown in the figure), and locking plates 8 are provided on both sides of the front inner support plate 1 and the rear support plate 3. The main body is initially defined by the insertion of the locking plates 8 into the locking grooves.

[0020] When the creases and embossing of the cardboard box are relatively inconspicuous or the corrugated strength of the cardboard material is high, the front inner support plate 1 and the rear support plate 3 are prone to rebound, meaning that their locking plates 8 are prone to coming out of the locking groove. To address this, existing technologies typically glue the locking plates 8 into the locking groove to prevent this coming out, but this causes inconvenience in production.

[0021] To address the aforementioned issues, this disclosure provides a latching groove 9 on each locking plate 8. As the box is assembled, the two locking plates 8 on the same side will bend and move closer to each other. At this time, the corresponding two latching grooves 9 can be engaged, so that the front inner support plate 1 and the rear support plate 3 are pulled together and are less likely to rebound.

[0022] In a preferred example, each snap groove 9 has the same shape, which simplifies the die-cutting process of the sheet metal. Specifically, the cross-section of the snap groove 9 is triangular, which gives the locking plate 8 a hook-like shape. After the box is assembled, the two locking plates 8 on the same side will fasten together like two hooks interlocking, thus counteracting the tendency of the front inner support plate 1 and the rear support plate 3 to move away from each other.

[0023] In some embodiments, the folding plate unit 6 includes a first folding plate 10 and a second folding plate 11 connected to each other. The second folding plate 11 has protrusions 12 on its side, and corresponding insertion holes 13 are provided on the front inner support plate 1 and / or the rear support plate 3. For example, when protrusions 12 are provided on both sides of the second folding plate 11, insertion holes 13 are provided on both the front inner support plate 1 and the rear support plate 3.

[0024] After the box body is assembled, the folding plate unit 6 folds into the space between the front inner support plate 1 and the rear support plate 3. At this time, the protrusion 12 will be inserted into the corresponding insertion hole 13, thereby maintaining the aforementioned locking groove (not shown in the figure) between the first folding plate 10 and the second folding plate 11. It can be understood that since the insertion hole 13 is opened on the front inner support plate 1 and the rear support plate 3, this reduces the width requirement of the locking plate 8, because the second folding plate 11 does not need to abut against the bottom plate 2 after folding, thus saving the manufacturing materials of the aircraft box and reducing the cost of consumables.

[0025] For example, both sides of the front outer support plate 5 are provided with buckle plates 14 for insertion into the locking grooves. The insertion of the buckle plates 14 into the locking grooves allows the cover to stably close the main body. In addition, the front outer support plate 5 is also provided with a locking buckle 15, and the front inner support plate 1 is provided with a corresponding locking hole 16. After the box is assembled, as the front outer support plate 5 closes to the front inner support plate 1, the locking buckle 15 and the locking hole 16 move closer to each other until the locking buckle 15 is inserted into the locking hole 16, making it difficult for the buckle plates 14 to fall out of the locking grooves at will.

[0026] In a preferred embodiment, the locking buckle 15 is adapted to the side of the front outer support plate 5 away from the top plate 4, while the locking hole 16 is located at the connection between the front inner support plate 1 and the bottom plate 2. This allows most of the structure disclosed herein to be formed by punching sheet metal, greatly simplifying the manufacturing process and improving the production efficiency of the aircraft box.

[0027] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
