Description

Technical Field

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

[0002] In the production and distribution of sheet-like products such as electronic components, decorative panels, and printed materials, packaging and transportation protection are crucial for ensuring product quality. Sheet-like products typically have high flatness requirements, are easily scratched, and have weak impact resistance. If shaking or collision occurs during transportation, it can easily lead to damage to the product's edges and corners, surface scratches, or internal structural damage. This not only affects the product's appearance but may also directly lead to product scrap, increasing the company's production costs and after-sales risks.

[0003] Currently, traditional corrugated cardboard boxes and corrugated cardboard boxes are the main packaging containers used for placing slab products. Traditional corrugated cardboard boxes are widely used due to their simple structure, easy folding, and low cost, but they have significant shortcomings in terms of positioning and cushioning protection for slab products. Most existing corrugated cardboard boxes have a hollow internal structure and lack dedicated restraint mechanisms. When slab products are placed inside, gaps easily form between the product and the box, causing continuous collisions and friction during transport. To alleviate this problem, some companies fill the boxes with cushioning materials such as foam and bubble wrap. While this provides some protection, it requires additional procurement of cushioning materials, increasing packaging costs and processes. Furthermore, materials like foam are difficult to degrade, which is inconsistent with the trend of green and environmentally friendly development.

[0004] Meanwhile, sheet-like products come in various specifications, and the thickness of different batches often varies. The internal space of traditional airplane boxes is fixed, and the limiting structure cannot be flexibly adjusted according to the product thickness, resulting in poor versatility. For thinner products, excessive filling with cushioning material can lead to resource waste, while insufficient filling will still fail to provide effective protection. For thicker products, the box may fail to close or the product may be damaged by compression.

[0005] Therefore, it is necessary to design an airplane box to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an airplane box. This invention can stably compress sheet-like products into the box body through a special structure, avoiding collisions during transportation. At the same time, the limiting structure can be adjusted according to the product thickness to adapt to different product specifications. It can also achieve quick disassembly of the limiting structure to meet diverse packaging needs and improve the safety and economy of packaging and transporting sheet-like products.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An airplane case includes a case body, the upper end of which is rotatably connected to a top cover via a first crease. The top cover is provided with a clamping assembly, which includes four V-shaped pieces disposed on the case body. The four V-shaped pieces are distributed at four corners, and each of the four V-shaped pieces has a limiting block at both ends. An L-shaped block is fixedly connected to the rear side of each of the limiting blocks. The top cover has multiple rectangular holes, and the multiple L-shaped blocks pass through the corresponding rectangular holes.

[0009] Preferably, the L-shaped block includes an X-axis piece and a Y-axis piece, and the connection between the X-axis piece and the Y-axis piece is rotatably connected by a second crease.

[0010] Preferably, the front side of the box body is provided with two insertion holes, the left and right sides of the top cover are rotatably connected to the side cover through the third fold, the upper end of the top cover is rotatably connected to the front cover through the fourth fold, and the left and right sides of the front cover are rotatably connected to the insertion piece through the fifth fold.

[0011] Preferably, the two insert pieces are semi-circular, and the upper ends of the two side covers are arc-shaped.

[0012] Preferably, the box body, top cover, side cover, front cover, insert piece, and V-shaped piece are all made of cardboard.

[0013] Preferably, the V-shaped piece is composed of two strips of cardboard, the two strips of cardboard are connected by a sixth fold, and the two strips of cardboard are connected to the corresponding limiting blocks by a seventh fold.

[0014] Preferably, the height of the front cover is adapted to the height of the front side of the box, the width of the side cover is consistent with the width of the left and right sides of the box, and the side cover has anti-slip texture on the side closest to the box.

[0015] Preferably, the length of the rectangular hole is 2mm-4mm longer than the length of the X-axis piece of the L-shaped block, and the width of the rectangular hole matches the thickness of the Y-axis piece of the L-shaped block.

[0016] Compared with existing technologies, the advantages of this device are:

[0017] 1. Compared with existing technologies, this device offers more reliable positioning and cushioning, effectively preventing damage to sheet-like products during transportation. The device uses V-shaped plates distributed at the four corners of the box to form a clamping assembly. Limiting blocks at both ends of the V-shaped plates, in conjunction with L-shaped blocks penetrating the rectangular holes in the top cover, stably compress sheet-like products within the box, creating multi-point limiting from the four corners. This completely solves the problem of products easily shaking and colliding with the box in traditional shipping containers. Simultaneously, the bending structure of the V-shaped plates itself possesses a certain degree of elastic cushioning, absorbing impact forces during transportation. The protective effect is far superior to traditional methods such as simply filling with foam or bubble wrap.

[0018] 2. Compared with the existing technology, this device can flexibly change the included angle between the V-shaped pieces by adjusting the fixed position of the L-shaped block at one end of the V-shaped piece in the rectangular hole of the top cover, thereby adjusting the overall support height of the V-shaped piece. This achieves precise positioning and buffering of plate-shaped products of different thicknesses, eliminating the need to customize special packaging for products of different specifications, greatly improving the versatility of packaging and reducing the packaging costs for enterprises.

[0019] 3. Compared with existing technologies, the V-shaped pieces of this device are installed and fixed by the insertion and removal of L-shaped blocks and rectangular holes in the top cover. For products that do not require positioning cushioning, multiple V-shaped pieces can be quickly removed from the box, allowing the box to return to a hollow state to adapt to different usage scenarios. Furthermore, the V-shaped pieces, side covers, front cover and other structures are all connected by folds and rotation, making folding and storage convenient. At the same time, the whole is made of cardboard, which meets green and environmental protection requirements and solves the problems of fixed cushioning structures and poor reusability in traditional packaging.

[0029] Reference Figures 1-3 An airplane case includes a case body 1. The upper end of the case body 1 is rotatably connected to a top cover 3 via a first crease. The top cover 3 is provided with a clamping assembly, which includes four V-shaped pieces 7 disposed on the case body 1. The four V-shaped pieces 7 are distributed at four corners. Each end of the four V-shaped pieces 7 is provided with a limiting block 8. The setting of the limiting block 8 can effectively prevent the V-shaped pieces 7 from moving upward when in contact with the product, thus preventing the limiting from occurring. Each of the multiple limiting blocks 8 is fixedly connected to an L-shaped block 10 on its rear side. The top cover 3 is provided with multiple rectangular holes 9. Each of the multiple L-shaped blocks 10 passes through the corresponding rectangular holes 9. The clamping assembly and the top cover 3 are detachably connected through the cooperation of the L-shaped blocks 10 and the rectangular holes 9.

[0030] The L-shaped block 10 includes an X-axis piece and a Y-axis piece. The connection between the X-axis piece and the Y-axis piece is rotatably connected by the second fold. After the L-shaped block 10 passes through the rectangular hole 9, the X-axis piece can be folded to make the L-shaped block 10 fit tightly against the upper surface of the top cover 3, forming a snap-fit ​​effect to prevent the L-shaped block 10 from falling out of the rectangular hole 9 during transportation, thereby ensuring the stable and reliable limiting effect of the pressing component. The V-shaped piece 7 is composed of two strips of cardboard. The connection between the two strips of cardboard is rotatably connected by the sixth fold. The connection between the two strips of cardboard and the corresponding limiting block 8 is rotatably connected by the seventh fold. The length of the rectangular hole 9 is 2mm-4mm longer than the length of the X-axis piece of the L-shaped block 10, and the width of the rectangular hole 9 matches the thickness of the Y-axis piece of the L-shaped block 10.

[0031] The box body 1 has two insertion holes 2 on the front side. The top cover 3 is connected to the side cover 4 on both sides through the third fold. The top cover 3 is connected to the front cover 5 on the upper end through the fourth fold. The front cover 5 is connected to the insertion piece 6 on both sides through the fifth fold. The two insertion pieces 6 are semi-circular. The upper ends of the two side covers 4 are curved. The box body 1, top cover 3, side cover 4, front cover 5, insertion piece 6 and V-shaped piece 7 are all made of cardboard. The height of the front cover 5 is matched with the height of the front side of the box body 1. The width of the side cover 4 is the same as the width of the left and right sides of the box body 1. The side cover 4 has anti-slip texture on the side close to the box body 1.

[0032] The functional principle of this utility model can be explained through the following operation: First, determine the installation state of the V-shaped piece 7 according to the thickness of the plate-shaped product to be packaged. By adjusting the through position of the L-shaped block 10 in the rectangular hole 9 of the top cover 3, and utilizing the fold rotation characteristics of the X-axis piece and Y-axis piece in the L-shaped block 10, fix the L-shaped block 10 in the preset position of the rectangular hole 9, thereby changing the bending angle and overall support height of the V-shaped piece 7, so that the four V-shaped pieces 7 distributed at the four corners form a limiting space that matches the thickness of the product.

[0033] The plate-shaped product is then placed inside the box 1, ensuring that the product is in full contact with the V-shaped sheet 7. The elastic buffering performance of the bending structure of the V-shaped sheet 7 will form a stable squeezing force on the product. Together with the limiting blocks 8 at both ends of the V-shaped sheet 7, the product can be positioned at multiple points, effectively preventing the product from moving around inside the box 1.

[0034] After placing the product, rotate the side covers 4 on both sides of the top cover 3 along the third fold line to make them perpendicular to the top cover 3. Then rotate the front cover 5 at the top of the top cover 3 along the fourth fold line to make it perpendicular to the top cover 3. Then rotate the top cover 3 downward to seal the top of the box 1. At this time, the two side covers 4 are in contact with the inner wall of the box 1, and the front cover 5 covers the front of the box 1. At the same time, the insert 6 is precisely inserted into the two insertion holes 2 on the front of the box 1 to complete the closure and fixation of the box 1.

[0035] When packaging products that do not require positioning cushioning, simply rotate the Y-axis piece of the L-shaped block 10 in the opposite direction to pull the L-shaped block 10 out of the rectangular hole 9, and the V-shaped piece 7 can be quickly removed, restoring the airplane box to its general packaging function.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
