Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly airplane box technology, and in particular to an environmentally friendly airplane box that does not require tape sealing. Background Technology

[0002] With the rapid development of the global economy and the improvement of consumption levels, the pressure of packaging waste on the environment is increasing. The tape used for sealing traditional airplane boxes is mostly made of plastic, which is difficult to degrade. A large amount of waste tape not only occupies a lot of land resources, but also causes long-term pollution to soil and water sources, threatening the ecological balance.

[0003] Airplane boxes are mainly composed of the box body (bottom plate, side plates, and cover plate), folding flaps (main and auxiliary flaps), crease lines, and locking and gluing structures. Based on the mechanical properties of corrugated cardboard and the stability of the folding structure, they have the characteristics of low cost and easy processing. They are used in e-commerce, express delivery and other scenarios, and are more efficient than ordinary cardboard boxes in sealing.

[0004] This eco-friendly airplane box is made of a single environmentally friendly corrugated cardboard box, including a bottom plate, side plates with sealing flaps, and a cover plate. The sealing is achieved by a structure with interlocking teeth and slots, and a locking tongue with perforations. It locks in place by using geometric interlocking and the elastic deformation and tear resistance of the material. It is tape-free, making it more environmentally friendly. It is quick to assemble, customizable, and suitable for e-commerce, fresh food, and gift scenarios.

[0005] Existing technologies for environmentally friendly aircraft boxes often lack sufficient mechanical sealing strength in their mechanical sealing structures, such as buckles and tongues. Under conditions of transportation vibration and compression, stress concentration can easily lead to loosening or deformation, resulting in a lack of continuous and stable locking force. Traditional aircraft box sealing relies on tape, which does not meet environmental protection requirements. Furthermore, adhesive residue can easily remain and contaminate the items during unpacking. The tape also needs to be manually removed during recycling, significantly increasing sorting costs. Therefore, an environmentally friendly aircraft box that does not require tape sealing is proposed to solve the above problems. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an environmentally friendly airplane box that does not require tape sealing. It aims to improve the problems of existing airplane boxes being prone to loosening or deformation, lacking fixation and easily loosening, and relying on tape for sealing, which does not meet environmental protection requirements.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An environmentally friendly airplane box that does not require tape sealing includes a box body, a locking mechanism fixedly connected inside the box body, a spring barb fixedly connected to the rear side of the locking mechanism, two slots two are opened inside the box body, two tongues two are fixedly connected to the bottom of the locking mechanism, a slot two is opened inside the box body, and a corrugated mechanism is fixedly connected inside the box body. The locking mechanism includes multiple fixing blocks. The outside of each fixing block is fixedly connected to the inside of the box body. Each fixing block has an elastic rubber block fixedly connected inside. Each fixing block has a limit ring fixedly connected inside. Each elastic rubber block has a sliding post fixedly connected to its front side. Each sliding post has a fixing component on its opposite side. Through the above technical solution: the box body serves as the basic load-bearing component, and the internal locking mechanism uses a fixing block, elastic rubber block, and limit ring to position and guide the sliding column. The sliding column cooperates with the fixing component to drive the second tongue to insert into the second slot. Combined with components such as elastic barbs, the box body and the lid are locked together without tape. At the same time, the corrugated mechanism inside the box provides cushioning protection to ensure the safety of transporting goods.

[0008] As a further description of the above technical solution: Preferably, the fixing component includes a box cover, the bottom of which is rotatably connected to the top of the box body, a connecting cover rotatably connected to the bottom of the box cover, and two tongues fixedly connected to the rear side of the connecting cover; Through the above technical solution: the fixing component opens and closes by rotating the bottom of the lid to the top of the box body. At the same time, the connecting cover that is rotatably connected to the bottom of the lid uses two fixed tongues on its rear side to insert into the corresponding slots of the box body, and cooperates with the locking mechanism to achieve a tight and stable connection between the box body and the lid.

[0009] As a further description of the above technical solution: Preferably, the corrugated structure includes a corrugated paper layer, a biodegradable plastic layer is fixedly connected to the outside of the corrugated paper layer, a face layer is fixedly connected to the outside of the biodegradable plastic layer, and a kraft paper layer is fixedly connected to the outside of the face layer. Through the above technical solutions, the corrugated structure enhances the pressure resistance, sealing, and environmental friendliness of the aircraft box through the cushioning of the corrugated paper layer, the waterproof and environmentally friendly properties of the biodegradable plastic layer, the enhanced connection of the face layer, and the wear-resistant protection of the kraft paper layer. The synergistic effect of these multiple layers protects the internal items and reduces the environmental burden.

[0010] As a further description of the above technical solution: Preferably, each of the plurality of sliding columns has a sliding groove inside, the inside of the fixing block is slidably connected to the sliding column, and the inside of the limiting ring is slidably connected to the inside of the sliding column; The above technical solution involves multiple sliding columns with sliding grooves, which, together with the fixing block and the limiting ring, provide guidance for the sliding column's own sliding, position it within the box, and limit its sliding range, ensuring that the components of the locking mechanism work precisely and stably during operation.

[0011] As a further description of the above technical solution: Preferably, the interior of the two tongues has two slots, the front side of the elastic barb is fixedly connected to the rear side of the tongue, and the interior of the box has two slots. Through the above technical solution: the two slots opened in the box body are used for the insertion of the tongue. The slot inside the tongue cooperates with the elastic barb fixed on its rear side. When the tongue is inserted into the slot, the elastic barb hooks into the slot, thereby achieving a firm connection and stable locking between the box body and the lid.

[0012] As a further description of the above technical solution: Preferably, the outer side of the first insert is slidably connected to the inner wall of the box body, and the outer side of the elastic barb is in contact with the interior of the box body; Through the above technical solution: the insert tongue slides into the inner wall of the box and engages with the inside of the box, and the two work together to achieve precise guidance and stable locking during the connection process between the box and the lid.

[0013] As a further description of the above technical solution: Preferably, the two second tongues are externally slidably connected to the inner wall of the box body, and the adjacent sides of the plurality of sliding pillars are in contact with the adjacent side of the first tongue; Through the above technical solution: two tongues slide into the inner wall of the box and cooperate with the box slots. Multiple sliding posts contact the tongue and push the tongue to move. The two work together to achieve a double stable connection between the box and the lid, ensuring the reliability of the aircraft box sealing.

[0014] As a further description of the above technical solution: Preferably, the rear side of the connecting cover contacts the front side of the box body, and the outer sides of the plurality of sliding pillars are slidably connected to the inside of the box body; Through the above technical solution: the rear side of the connecting cover fits against the front side of the box body, and multiple sliding pillars slide within the box body and push the connecting cover, so that the first tongue is precisely inserted into the first slot, achieving a tight connection between the box body and the box cover.

[0015] This utility model has the following beneficial effects: 1. In this utility model, the lid is rotatably connected to the top of the box body. The connecting cover drives the first tongue to rotate downward. The sliding column slides under the cooperation of the elastic rubber block and the limiting ring, so that the first tongue is inserted into the inside of the first slot. The second tongue at the bottom of the locking mechanism is inserted into the second slot of the box body. The mechanical locking structure of the elastic barb and the groove is firmly sealed and not easy to loosen. The structure is simple, the production cost is low, it is suitable for large-scale production, the operation is simple, the sealing speed is fast, and it is suitable for automated production lines.

[0016] 2. In this utility model, when the corrugated mechanism is working, the innermost corrugated paper layer plays a core buffering role. It absorbs external impact through its own wave-shaped structural deformation to protect the internal items. The biodegradable plastic layer is tightly attached to the outside of the corrugated paper layer, providing strength and waterproofness, while also having biodegradable properties, thus taking into account both performance and environmental protection requirements.

[0019] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0020] Example: An environmentally friendly airplane box that requires no tape sealing, see reference. Figures 2 to 4The package includes a box body 1, with a locking mechanism 2 fixedly connected inside the box body 1. The box body 1 serves as the main frame of the airplane box, providing an installation base and load-bearing space for the internal structures. A spring hook 3 is fixedly connected to the rear side of the locking mechanism 2. Through the coordinated operation of the internal components, the locking mechanism 2 applies a stable locking force to the box lid 261, enhancing the sealing and security of the packaging and preventing items from falling or being impacted by external forces. When the tongue 263 is inserted into the slot 265, the spring hook 3 hooks into the slot 264, further restricting the movement of the box lid 261. Two slots 4 are provided inside the box body 1. Two tongues 5 are fixedly connected to the bottom of the locking mechanism 2. The slots 4 ensure that the tongues 5 are in the correct position inside the box body 1, enabling the locking mechanism 2 to function stably. A slot 6 is provided inside the box body 1, providing guidance and accommodating space for the insertion of the tongues 5, ensuring that the tongues 5 can be accurately inserted into the slot 4. A corrugated mechanism 7 is fixedly connected inside the box body 1. Specifically, the box body 1 is the main frame that supports the internal structure. The locking mechanism 2, together with the elastic barb 3, applies force to the box lid 261 to enhance the sealing and safety. The barb 3 hooks into the slot 1 264 to reinforce the connection. The slot 2 4 and the slot 2 6 cooperate with the tongue 2 5 to ensure the stable operation of the locking mechanism 2. The corrugated mechanism 7 enhances the buffer. The whole system achieves a tape-free seal, which is environmentally friendly and practical.

[0021] The locking mechanism 2 includes multiple fixing blocks 21, which are externally fixedly connected to the inside of the housing 1. The fixing blocks 21 ensure the relative position stability of each component inside the housing 1, enabling the locking mechanism 2 to function normally. Each fixing block 21 has an elastic rubber block 22 fixedly connected inside, allowing the sliding column 24 to slide smoothly within the fixing block 21, ensuring smooth operation of the locking mechanism 2. Each fixing block 21 also has a limit ring 23 fixedly connected inside, preventing the sliding column 24 from sliding excessively and detaching from the fixing block 21, thus ensuring the normal operation and structural integrity of the locking mechanism 2. Each elastic rubber block 22 has a sliding... The sliding post 24 cooperates with the fixing component 260 to lock and unlock the lid 261. By sliding, it changes its position and pushes the first tongue 263 to move. Each of the sliding posts 24 has a sliding groove 25 inside. The sliding groove 25 allows the limiting ring 23 to move inside the sliding post 24. In coordination with the overall movement of the sliding post 24, the fixing block 21 is slidably connected to the sliding post 24, and the limiting ring 23 is slidably connected to the inside of the sliding post 24. By sliding, it changes its position and pushes the first tongue 263 to move, thereby controlling the connection state between the box body 1 and the lid 261. The fixing component 260 is provided on the opposite side of the sliding post 24.

[0022] Specifically, the fixing block 21 is fixed inside the box body 1 to ensure the stability of the positions of each component of the locking mechanism 2 and to provide a foundation for the operation of the mechanism. The elastic rubber block 22 assists the sliding column 24 to slide smoothly, reduce friction, and ensure smooth operation of the mechanism. The limiting ring 23 restricts the sliding range of the sliding column 24 to prevent it from falling off the fixing block 21, thus maintaining the integrity of the mechanism structure and normal function. The sliding column 24 slides inside the fixing block 21 and uses the sliding groove 25 and the limiting ring 23 to push the tongue 263 to move, cooperating with the fixing component 260 to achieve precise locking and unlocking control of the box body 1 and the lid 261.

[0023] The fixing assembly 260 includes a cover 261. Through rotation and insertion between its components, the fixing assembly 260 tightly connects the cover 261 to the box body 1. The bottom of the cover 261 is rotatably connected to the top of the box body 1. The cover 261, in cooperation with the connecting cover 262 and the locking mechanism 2, enables the opening, closing, and locking of the box body 1. The bottom of the cover 261 is rotatably connected to the connecting cover 262. The connecting cover 262's tongue 263 inserts into a slot 265 inside the box body 1, cooperating with the locking mechanism 2. The rear side of the connecting cover 262 contacts the front side of the box body 1. Multiple sliding posts 24 are externally slidably connected to the inside of the box body 1. Two tongues 263 are fixedly connected to the rear side of the connecting cover 262. The tongues 263, through contact with the sliding posts 24, complete the insertion and removal actions under the push of the sliding posts 24, controlling the connection state. The external sliding connection of the tongues 263 is... The inner wall of the box body 1 has two external sliding tongues 5 slidably connected to the inner wall of the box body 1. The adjacent sides of multiple sliding posts 24 are in contact with the adjacent sides of the first tongue 263. The first tongue 263 is inserted into the slot 265 inside the box body 1 and cooperates with the slot 264, the elastic barb 3, etc. to lock the box body 1 and the lid 261. The outer side of the elastic barb 3 is in contact with the inside of the box body 1. The two slots 264 are opened inside the two tongues 263. When the first tongue 263 is inserted into the slot 264, the elastic barb 3 hooks into the slot 264, restricting the movement of the lid 261 and ensuring a stable connection. The front side of the elastic barb 3 is fixedly connected to the rear side of the first tongue 263. The two slots 265 are opened inside the box body 1. The slots 265 ensure that the first tongue 263 can be accurately inserted and cooperate with other components to realize the connection and locking of the box body 1 and the lid 261.

[0024] Specifically, in the fixing component 260, the lid 261 is rotatably connected to the top of the box body 1. Through cooperation with the connecting cover 262 and the locking mechanism 2, it can open, close and lock. The connecting cover 262 drives the tongue 263 to insert into the slot 265 of the box body 1. It cooperates with the sliding post 24 of the locking mechanism 2. The insertion and removal are completed under the push of the sliding post 24 to control the connection state. After the tongue 263 is inserted, its internal slot 264 cooperates with the spring hook 3. The hook 3 hooks into the slot to restrict the movement of the lid 261 and enhance the stability. The slot 265 provides a precise insertion path and positioning for the tongue 263 to ensure that all components cooperate and achieve a tight and stable connection between the box body 1 and the lid 261.

[0025] Reference Figure 1 , Figure 5 The corrugated structure 7 includes a corrugated paper layer 71. When compressed, the corrugated paper layer 71 deforms to absorb energy, protecting the internal items from damage. A biodegradable plastic layer 72 is fixedly connected to the outside of the corrugated paper layer 71. The biodegradable plastic layer 72 ensures the strength and waterproofness of the aircraft box while having biodegradable properties, reducing environmental pollution. A face layer 73 is fixedly connected to the outside of the biodegradable plastic layer 72. The face layer 73 serves as an intermediate transition layer, enhancing the connection strength and integrity between the various material layers of the aircraft box, enabling each layer to work together to improve the performance of the aircraft box. A kraft paper layer 74 is fixedly connected to the outside of the face layer 73. The kraft paper layer 74 has high strength and wear resistance, providing external protection for the aircraft box and resisting external forces such as friction and scratches during transportation, maintaining the integrity of the aircraft box's appearance and the safety of the internal items.

[0026] The corrugated paper layer 71 absorbs compressive energy through structural deformation to protect the items; the biodegradable plastic layer 72 ensures the strength and waterproofness of the aircraft box and has biodegradable and environmentally friendly properties; the core layer 73 enhances the connection strength of each material layer and promotes synergistic performance improvement; and the kraft paper layer 74 resists external friction and scratches with its high strength and abrasion resistance, protecting the exterior of the aircraft box and the items inside. The four layers of materials work together to give the corrugated structure 7 the functions of cushioning, environmental protection, structural stability and external protection.

[0027] Working principle: When this environmentally friendly airplane box is in operation, the lid 261 is rotatably connected to the top of the box body 1. The connecting cover 262 drives the first tongue 263 to rotate downward and insert into the slot 265 of the box body 1. The sliding column 24 slides with the cooperation of the elastic rubber block 22 and the limiting ring 23, so that the first tongue 263 is engaged in the inside of the slot 264, and the elastic barb 3 is engaged in the slot 4, restricting the movement of the lid 261. At the same time, the second tongue 5 at the bottom of the locking mechanism 2 is inserted into the slot 6 of the box body 1, completing the double locking of the box body 1 and the lid 261. No tape sealing is required, which meets environmental protection requirements and is easy to recycle. The mechanical locking structure of the elastic barb 3 and the groove is firmly sealed and not easy to loosen. The structure is simple, the production cost is low, it is suitable for large-scale production, the operation is simple, the sealing speed is fast, and it is suitable for automated production lines.

[0028] When the corrugated structure 7 is in operation, the innermost corrugated paper layer 71 plays a core buffering role, absorbing external impact through its own wave-shaped structural deformation to protect the internal items. The biodegradable plastic layer 72 is tightly bonded to the outside of the corrugated paper layer 71, providing strength and water resistance, while also possessing biodegradable properties, taking into account both performance and environmental protection requirements. The face layer 73 serves as a transition layer, enhancing the connection strength between the various material layers, making the overall structure more stable, and helping each layer work together to improve the performance of the aircraft box. The outermost kraft paper layer 74, with its high strength and abrasion resistance, resists friction and scratches during transportation, protecting the appearance of the aircraft box and the safety of the internal items, jointly ensuring the protective function of the aircraft box during transportation.
