Description

Technical Field

[0001] This utility model relates to the field of aviation transport auxiliary equipment technology, and in particular to a detachable fireproof and heat-insulating cover for aviation cargo. Background Technology

[0002] In the air cargo sector, safety during transport is paramount, especially for perishable goods such as fresh food. Strict temperature control of the transport environment is essential, along with excellent fire resistance to prevent damage from environmental changes or accidental fires. Fireproof and heat-insulating covers, commonly used protective equipment in air cargo, directly impact the safety and reliability of cargo transport.

[0003] Currently, existing fireproof and heat-insulating covers for air cargo are mainly divided into two categories: one-piece molded type and simple splicing type. Among them, the one-piece molded fireproof and heat-insulating cover has a stable structure and good fireproof and heat-insulating effect, but it has obvious defects. This type of cover is mostly a fixed structure and cannot be disassembled or folded. When it is not in use, it occupies a lot of space and increases warehousing and transportation costs.

[0004] The simple splicing fireproof and heat insulation cover forms a protective structure by splicing multiple panels, which solves the problem of universality of the one-piece molded type to a certain extent. However, it still has many shortcomings in practical applications. The splicing structure mostly uses traditional connection methods such as bolts and buckles. The assembly and disassembly process requires the use of professional tools, which is cumbersome and inefficient, and it is difficult to meet the needs of rapid loading and unloading in air cargo scenarios.

[0005] Based on the shortcomings of the existing technology, there is an urgent need for an air cargo fireproof and heat-insulating cover that is easy to assemble and disassemble, while also ensuring stable fireproof and heat insulation performance, in order to meet the actual needs of the air cargo industry, reduce warehousing and transportation costs, and improve the safety and reliability of cargo transportation. Utility Model Content

[0006] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a detachable fireproof and heat-insulating cover for air cargo, which can solve the above-mentioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a detachable fireproof and heat-insulating cover for air cargo, including a base, with a support foot fixedly connected to the bottom of the base, and a cover assembly provided on the base;

[0008] The cover assembly is provided with a hinge assembly, which includes a mounting plate. The mounting plate is fixedly connected to two adjacent cover assemblies, and a rotating shaft is fixedly connected to the mounting plate. The mounting plate is rotatably connected through the rotating shaft.

[0009] A connecting component is provided at the outward end of the cover assembly;

[0010] A base plate is fixedly connected to the base, and there are four square mounting slots on the base. A disassembly component is installed in the mounting slot, and a canopy is installed on the cover component.

[0011] Preferably, the cover assembly includes a vacuum insulation panel, which is disposed above the base. An elastic groove is provided at one end of the vacuum insulation panel facing outward. A wear-resistant layer is fixedly connected to the outer side of the vacuum insulation panel, and a fresh produce adaptable layer is fixedly connected to the inner side of the vacuum insulation panel.

[0012] Preferably, the lower end of the vacuum insulation panel is fixedly connected with a claw, and the upper end of the vacuum insulation panel is provided with a slot.

[0013] Preferably, a plug is fixedly connected to the lower part of the canopy, and the plug fits into the slot.

[0014] Preferably, the connecting assembly includes two connectors, the other ends of which are rotatably connected by a hinge assembly, and one end of each connector is fixedly connected with a tenon that engages with an elastic groove.

[0015] Preferably, the cross-section of the tenon is semi-circular.

[0016] Preferably, the disassembly assembly includes a spring, which is fixedly connected to one side of the mounting groove, and the other end of the spring is fixedly connected to a retaining plate. A top plate is fixedly connected to the middle of the retaining plate, and a push plate passes through the side of the bottom plate.

[0017] Preferably, an anti-slip pad is fixedly connected to the bottom of the support leg.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. When disassembling and storing this detachable fireproof and heat-insulating cover for air cargo, first lift the top to disengage the insert rod below the top from the slot at the top of the cover assembly, thus disassembling the top. Then, disconnect the connection between the four side panels. Use external force to separate the tenon from the elastic slot in the connecting assembly. Utilize the elastic deformation of the elastic slot to apply a reverse force to disengage the tenon, thus releasing the fixed connection between adjacent cover assemblies. Next, operate the disassembly assembly to separate the cover assembly from the base. Push the top plate into the mounting slot. The top plate moves the locking plate fixedly connected to it synchronously. At this time, the locking plate compresses the spring, and the spring is in a contracted state. The locking plate disengages from the limiting clamp of the locking claw. At this time, the cover assembly can be lifted up to disengage the locking claw from the mounting slot, thus completing the disassembly of a single cover assembly from the base. Follow the above steps to disassemble all four cover assemblies from the base, ultimately achieving complete disassembly of the entire equipment for easy separate storage and reduced space occupation.

[0020] 2. This detachable fireproof and heat-insulating cover for air cargo can be folded for storage without completely disassembling the equipment. The top can be removed first, and then the connecting components between the four side panels can be released, separating the tenons from the elastic slots. Since the adjacent cover components are rotatably connected by the rotating shaft of the hinge assembly, after releasing the fixing of the connecting components, the adjacent cover components can be rotated around the rotating shaft, causing the four side panels to fold inward and close together, realizing the folding and storage of the equipment without completely disassembling each part, thus improving the ease of operation.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0034] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0035] Please see Figure 1-8 This utility model provides a technical solution: a detachable fireproof and heat-insulating cover for air cargo, including a base 1, a support leg 2 fixedly connected to the bottom of the base 1, a cover assembly on the base 1, and an anti-slip pad fixedly connected to the bottom of the support leg 2.

[0036] The assembly process is based on the base 1 as the support. The overall structure is built by the precise fitting of each component. First, the base 1 is stably placed in the designated position by the support legs 2 fixedly connected to it. The support legs 2 provide stable support for the entire device and prevent the base 1 from directly rubbing against the contact surface or getting damp.

[0037] The cover assembly includes a vacuum insulation panel 4, which is positioned above the base 1. An elastic slot 8 is provided at one outward end of the vacuum insulation panel 4. A wear-resistant layer 3 is fixedly connected to the outer side of the vacuum insulation panel 4, and a fresh food adaptable layer 5 is fixedly connected to the inner side of the vacuum insulation panel 4. A claw 14 is fixedly connected to the lower end of the vacuum insulation panel 4, and a slot 11 is provided at the upper end of the vacuum insulation panel 4.

[0038] The cover assembly is provided with a hinge assembly, which includes a mounting plate 6. The mounting plate 6 is fixedly connected to two adjacent cover assemblies. A rotating shaft 7 is fixedly connected to the mounting plate 6, and the mounting plate 6 is rotatably connected through the rotating shaft 7.

[0039] The outer end of the cover assembly is provided with a connecting component, which includes a connector 10. One end of the connector 10 is fixedly connected to a tenon 9. The tenon 9 has a semi-circular cross-section. The other ends of the two connectors 10 are rotatably connected through a hinge assembly. The tenon 9 fits into the elastic slot 8.

[0040] Two adjacent cover components are rotatably connected by a hinge assembly. The mounting plates 6 in the hinge assembly are fixed at corresponding positions of the two adjacent cover components. The mounting plates 6 are rotatably engaged by a rotating shaft 7, allowing the adjacent cover components to be angled around the rotating shaft 7. At the same time, the connecting component set at the outward end of the cover component completes the fixed connection of the adjacent cover components. The tenon 9 at one end of the connector 10 in the connecting component precisely matches the elastic slot 8 opened on the other cover component. The elastic deformation characteristics of the elastic slot 8 are used to achieve a tight engagement of the tenon 9, thereby firmly connecting the two cover components to form a complete partition structure on one side. In the above manner, the four side partitions are assembled by the cooperation of the hinge assembly and the connecting component. The four corners of the four side partitions are fixedly installed to the base 1 by the disassembly assembly, forming a closed side protection structure.

[0041] A base plate 15 is fixedly connected to the base 1. The base 1 has a square mounting groove 16, and a disassembly component is provided in the mounting groove 16.

[0042] The disassembly assembly includes a spring 17, which is fixedly connected to one side of the mounting groove 16. The other end of the mounting groove 16 is fixedly connected to a retaining plate 18, and the middle of the retaining plate 18 is fixedly connected to a top plate 19, which penetrates the side of the base 1.

[0043] After the claw 14 is inserted into the mounting slot 16, the clamping plate 18 limits and fixes the claw 14, pushes the top plate 19, the top plate 19 drives the clamping plate 18, the clamping plate 18 moves away from the claw 14 and is disassembled, and the mounting slot 16 resets the top plate 19.

[0044] The cover assembly is provided with a canopy 12, and a plug rod 13 is fixedly connected to the bottom of the canopy 12. The plug rod 13 fits into the slot 11.

[0045] Two cover components and connecting components form a side partition, and the four corners of the four side partitions are fixedly installed by disassembly components;

[0046] Next, the disassembly assembly is operated to separate the cover assembly from the base 1. The top plate 19 is pushed into the mounting groove 16. The top plate 19 drives the clamping plate 18 fixedly connected to it to move synchronously. At this time, the clamping plate 18 compresses the spring 17. The spring 17 is in a contracted state. The clamping plate 18 is released from the limiting clamping of the claw 14. At this time, the cover assembly can be lifted up so that the claw 14 is released from the mounting groove 16, completing the disassembly of a single cover assembly from the base 1. The above steps are followed to complete the disassembly of the four cover assemblies from the base 1, and finally the complete disassembly of the entire device is achieved, which is convenient for separate storage and reduces the space occupied.

[0047] Working principle: The assembly process is based on the base 1 as the support. The overall structure is built by the precise fitting of each component. First, the base 1 is stably placed in the designated position by the support legs 2 fixedly connected below it. The support legs 2 provide stable support for the entire equipment and prevent the base 1 from directly rubbing against the contact surface or getting damp. The base plate 15 fixed on the base 1 is used to support the cover components and the goods to be transported, ensuring the flatness of the goods.

[0048] Each housing assembly has a vacuum insulation panel 4 as its core body. The claws 14 fixedly connected to its bottom are aligned with the mounting slots 16 on the four sides of the base 1 and inserted. At this time, the disassembly component in the mounting slot 16 begins to function. The spring 17 in the disassembly component is in a naturally extended state, pushing the clamping plate 18 fixedly connected to it to the initial limit position. When the claws 14 are fully inserted into the mounting slot 16, the clamping plate 18 forms a limit clamp on the claws 14 under the elastic force of the spring 17, thereby stably fixing the single housing assembly on the base 1.

[0049] Two adjacent cover components are rotatably connected by a hinge assembly. The mounting plates 6 in the hinge assembly are fixed at corresponding positions of the two adjacent cover components. The mounting plates 6 are rotatably engaged by a rotating shaft 7, allowing the adjacent cover components to be angled around the rotating shaft 7. At the same time, the connecting component set at the outward end of the cover component completes the fixed connection of the adjacent cover components. The tenon 9 at one end of the connector 10 in the connecting component precisely matches the elastic slot 8 opened on the other cover component. The elastic deformation characteristics of the elastic slot 8 are used to achieve a tight engagement of the tenon 9, thereby firmly connecting the two cover components to form a complete partition structure on one side. In the above manner, the four side partitions are assembled by the cooperation of the hinge assembly and the connecting component. The four corners of the four side partitions are fixedly installed to the base 1 by the disassembly assembly, forming a closed side protection structure.

[0050] Align the plug 13, which is fixedly connected to the bottom of the canopy 12, with the slot 11 opened at the top of the cover assembly. After insertion, the canopy 12 and the four side partitions are precisely matched, and the assembly of the entire fireproof and heat-insulating cover is completed, forming a closed cargo protection space.

[0051] The fireproof and heat insulation function of this equipment is mainly achieved through the core structure of the enclosure assembly. The enclosure assembly uses vacuum insulation board 4 as the core heat insulation and fireproof layer. Vacuum insulation board 4 utilizes the physical property that heat is difficult to conduct in a vacuum environment to effectively block external heat from entering the enclosure and prevent the temperature inside the enclosure from dissipating rapidly, thus achieving excellent heat insulation effect. In addition, vacuum insulation board 4 itself has good fireproof performance and can prevent external fire sources from spreading into the enclosure, ensuring the safety of goods.

[0052] The wear-resistant layer 3 fixedly connected to the outer side of the vacuum insulation panel 4 can enhance the surface wear resistance of the cover components, avoid damage to the vacuum insulation panel 4 caused by collisions and friction between the equipment and other objects during air transport, and ensure the integrity of the fireproof and heat-insulating structure. The fresh food adaptable layer 5 fixedly connected to the inner side of the vacuum insulation panel 4 can adapt to the transportation needs of fresh goods, reduce the damage to goods caused by direct contact between the vacuum insulation panel 4 and the goods, and further improve the heat insulation effect inside the cover to maintain the appropriate temperature environment required by the goods.

[0053] The enclosed space formed after assembly, combined with the core function of the vacuum insulation panel 4, enables the entire equipment to effectively isolate external high temperature, fire source and low temperature environment, providing a stable and safe transportation environment for internal goods, and meeting the stringent requirements of air freight for fire prevention and heat insulation.

[0054] When the equipment needs to be disassembled and stored, first lift the top 12 upwards so that the insert 13 below the top 12 disengages from the slot 11 at the upper end of the cover assembly, thus completing the disassembly of the top 12. Then, disconnect the connection between the four side partitions and use external force to separate the tenon 9 in the connecting assembly from the elastic groove 8. By utilizing the elastic deformation of the elastic groove 8, a reverse force can be applied to disengage the tenon 9, thus releasing the fixed connection between adjacent cover assemblies.

[0055] Next, the disassembly assembly is operated to separate the cover assembly from the base 1. The top plate 19 is pushed into the mounting groove 16. The top plate 19 drives the clamping plate 18 fixedly connected to it to move synchronously. At this time, the clamping plate 18 compresses the spring 17. The spring 17 is in a contracted state. The clamping plate 18 is released from the limiting clamping of the claw 14. At this time, the cover assembly can be lifted up so that the claw 14 is released from the mounting groove 16, completing the disassembly of a single cover assembly from the base 1. The above steps are followed to complete the disassembly of the four cover assemblies from the base 1, and finally the complete disassembly of the entire device is achieved, which is convenient for separate storage and reduces the space occupied.

[0056] When the equipment does not need to be completely disassembled and only needs to be folded for storage, the top 12 can be removed first without removing the fixing of the cover assembly and the base 1. Then, the fitting of the connecting components between the four side partitions is released, and the tenon 9 separates from the elastic slot 8. Since the adjacent cover assemblies are rotatably connected through the rotating shaft 7 of the hinge assembly, after the fixing of the connecting components is released, the adjacent cover assemblies can be rotated around the rotating shaft 7 to make the four side partitions fold inward and close together, so as to realize the folding storage of the equipment without completely disassembling each part, thus improving the ease of operation.

[0057] After the disassembly operation is completed, the external force on the top plate 19 is released. The spring 17 in the contracted state pushes the locking plate 18 to reset under the action of elastic restoring force, and drives the top plate 19 back to the initial position, so as to prepare for the next installation of the cover assembly and ensure the reusability of the disassembled assembly.

[0058] Relying on the rotational engagement of the hinge components, the precise fit of the tenon 9-elastic slot 8, and the elastic limiting structure of the claw 14-plate 18, the overall assembly can be completed quickly without complicated tools, reducing the operational threshold.

[0059] With vacuum insulation panel 4 as the core layer, the vacuum insulation properties are used to isolate the heat conduction between the inside and outside, and it also has good fire resistance. The outer wear-resistant layer 3 protects the core structure from collision damage, and the inner fresh food adaptable layer 5 adapts to the special cargo needs and strengthens the insulation, ensuring the safety of the cargo in all aspects.

[0060] It is flexible to disassemble and fold, and has a high space utilization rate. When fully disassembled, the canopy 12, side partitions, base 1 and other components can be separated and stored separately, which greatly reduces the storage space occupied. When it is not necessary to fully disassemble, the side partitions can be folded directly to meet the flexible storage needs in air cargo scenarios.

[0061] Modular design allows individual components such as the cover and canopy 12 to be replaced independently, avoiding overall scrapping. The spring 17 of the disassembled components has a reset function to ensure repeated and stable use, and the wear-resistant layer 3 improves the structure's resistance to damage.

[0062] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
