Description

Technical Field

[0001] This utility model relates to the field of flame-retardant cover loading and unloading technology, and in particular to a rapid loading and unloading device for flame-retardant covers for air cargo. Background Technology

[0002] With the rapid development of the global economy, the air freight industry has shown a sustained growth trend. More and more goods need to be transported by air to meet the demand for fast and efficient logistics. Air freight involves a wide variety of goods, including some flammable, explosive, and other potentially hazardous items. To ensure flight safety, the requirements for fire prevention and flame retardant measures for cargo are becoming increasingly stringent, and flame retardant covers, as an important fire protection device, are in increasing demand.

[0003] Chinese patent CN214729604U discloses an aviation cargo net connector, including a deck body. The outer surface of the deck body has threaded holes, and threaded posts are threaded into the inner part of the threaded holes. A first mounting ring is fixedly connected to the outer surface of the threaded posts, and multiple connecting rods are hinged to the outer surface of the first mounting ring. This aviation cargo net connector is small in size and easy to carry. It can be positioned on the outside of the material according to its size, offering flexibility and applicability to materials of different sizes. The extended plate expands the cross-sectional area of ​​the device, and the threaded connection between the threaded posts and the threaded holes ensures a secure connection that is not easily detached, making disassembly and installation very convenient. Furthermore, the device can also be used by providing threaded holes for threaded connection with the threaded posts on the cargo pallet. Its versatility allows for more flexible weight distribution on aircraft, increasing cargo capacity.

[0004] This technical solution involves creating threaded holes on the outer surface of the deck body, with threaded posts connected to the inside of the threaded holes, and a first mounting ring fixedly connected to the outer surface of the threaded posts. However, when installing other equipment used to protect cargo, such as flame-retardant covers, multiple people are required to complete the installation. This not only increases labor costs but also makes it easy for operational errors to occur due to poor personnel coordination, further affecting the smooth progress of loading and unloading operations. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a rapid loading and unloading device for flame-retardant covers on air cargo. Through the cooperation of a sliding latch and a limiting slider inside the fixed base, the flame-retardant cover can be clamped and released, thereby achieving rapid loading and unloading of the flame-retardant cover without the need for multiple people to cooperate in the installation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid loading and unloading device for flame-retardant covers of air cargo, comprising a base plate, a loading and unloading mechanism disposed on the top of the base plate, an extension mechanism disposed on the top of the base plate, the loading and unloading mechanism disposed at the bottom of the extension mechanism, the loading and unloading mechanism comprising multiple fixed seats, the interior of the multiple fixed seats being slidably connected to the top of the base plate, a sliding latch being slidably connected to the inner wall of the fixed seat, a limiting slider being slidably connected to the interior of the fixed seat, limiting plates being fixedly connected to both sides of the fixed seat, control sliders being slidably connected to the interior of the limiting plates, a support component for supporting operation being fixedly connected to the interior of the fixed seat, and an active component for providing movement space being provided inside the fixed seat;

[0007] As a further description of the above technical solution:

[0008] The extension mechanism includes multiple arc plates, the bottom of the multiple arc plates is slidably connected to the top of the base plate, the top of two arc plates is fixedly connected to a support frame, two connecting ropes are fixedly connected to the adjacent sides of the two support frames, multiple fixing ropes are fixedly connected to the adjacent sides of the two support frames, and a connecting buckle is fixedly connected to the outside of the fixing ropes.

[0009] As a further description of the above technical solution:

[0010] The tops of the two support frames on opposite sides of the top of the base plate are fixedly connected to movable shafts. Two support columns are rotatably connected to the outside of the movable shafts. Two fixed columns are cross-fixedly connected to the adjacent sides of the two support columns. The bottoms of the multiple support columns are fixedly connected to the top of the fixed base.

[0011] As a further description of the above technical solution:

[0012] The support assembly includes a support tube, the outside of which is fixedly connected to the inside of the fixed base, and a movable tube is slidably connected inside the support tube, with a spring sleeved inside the movable tube.

[0013] As a further description of the above technical solution:

[0014] The sliding component includes slots, two of which are formed on both sides of the fixed base, and the fixed base has a movable groove inside.

[0015] As a further description of the above technical solution:

[0016] The outer side of the sliding latch is slidably connected to the inside of the movable groove, and the top of the base plate is slidably connected to the inside of the latch.

[0017] As a further description of the above technical solution:

[0018] The movable tube, i.e. the side away from the support tube, is fixedly connected to the outside of the limiting slider. The two sides of the limiting slider are supported on the side close to the control slider. The outside of the sliding jaw is supported on the outside of the limiting slider.

[0019] As a further description of the above technical solution:

[0020] The externally fixed connections of the plurality of connecting buckles are made of soft flame-retardant covers, and the externally fixed connections of the support column and the fixed column are made of hard flame-retardant covers.

[0021] The beneficial effects of this utility model are as follows:

[0022] (1) This utility model achieves the clamping and loosening of the flame retardant cover by the cooperation of the sliding mouth and the limiting slider inside the fixed seat. By controlling the slider to slide inside the limiting plate, the movement direction and range of the control slider are limited, thereby indirectly controlling the movement of the limiting slider and the sliding mouth, thus achieving quick loading and unloading of the flame retardant cover without the need for multiple people to cooperate in the installation.

[0023] (2) This utility model solves the problem that the flame retardant cover is heavy, difficult to operate during installation and disassembly, and easy to scratch goods, and difficult to install quickly. When an external force is applied to the arc plate, the arc plate slides on the bottom plate and the top plate of the base plate. This causes the support frame, connecting rope, fixing rope and other components to move together.

[0024] In summary, this utility model has the advantages of quick loading and unloading and no need for multiple operators. Attached Figure Description

[0033] Example 1

[0034] like Figures 3 to 5 As shown, this embodiment provides a rapid loading and unloading device for flame-retardant covers of air cargo, including a base plate 1. The base plate 1 serves as the basic support component of the entire device, used to fix the cargo, and provides a platform for the installation and operation of the loading and unloading mechanism 2 and the extension mechanism 3, ensuring the stable operation of each mechanism. The loading and unloading mechanism 2 is provided on the top of the base plate 1, and the extension mechanism 3 is provided on the top of the base plate 1. The loading and unloading mechanism 2 is provided at the bottom of the extension mechanism 3.

[0035] The loading and unloading mechanism 2 includes multiple fixed seats 201, which are the main support structures of the loading and unloading mechanism 2. The interior of each fixed seat 201 is slidably connected to the top of the base plate 1. A sliding latch 204 is slidably connected to the inner wall of each fixed seat 201 for locking and unlocking. A limiting slider 205 is slidably connected inside each fixed seat 201, controlling the movement and limiting the position of the sliding latch 204. Limiting plates 207 are fixedly connected to both sides of each fixed seat 201, providing a sliding channel and limiting the movement of the control slider 206. Control sliders 206 are slidably connected inside each limiting plate 207, restricting the direction and range of movement of the limiting slider 205. A support assembly for supporting operation is fixedly connected inside each fixed seat 201. The support assembly includes a support tube 208, which provides support and guidance for the movable tube 209. The support tube 208 is externally fixedly connected inside the fixed seat 201. The support tube 208 has a sliding connection to a movable tube 209. The movable tube 209 cooperates with a spring 2010 to transmit the elastic force of the spring 2010 to the limiting slider 205. The movable tube 209 is fitted with a spring 2010, which provides elastic force. The fixed base 201 has a movable component inside to provide movement space. The sliding component includes a slot 202, which provides a sliding channel for the base plate 1. Two slots 202 are opened on both sides of the fixed base 201. The base 201 has an internal movable groove 203, which provides space for the sliding latch 204 to move. The external part of the sliding latch 204 is slidably connected to the inside of the movable groove 203. The top of the base plate 1 is slidably connected to the inside of the latch 202. The movable tube 209, i.e. the side away from the support tube 208, is fixedly connected to the outside of the limiting slider 205. The two sides of the limiting slider 205 are supported on the adjacent side of the control slider 206. The external part of the sliding latch 204 is supported on the outside of the limiting slider 205.

[0036] Example 2

[0037] like Figure 1 , Figure 2 and Figure 6As shown, this embodiment provides a rapid loading and unloading device for flame-retardant covers of air cargo. The extension mechanism 3 includes multiple arc plates 301, which serve as the bottom support components of the extension mechanism 3. They slide on the base plate 1, driving the entire extension mechanism 3 to adjust its position. The bottoms of the multiple arc plates 301 are slidably connected to the top of the base plate 1. Support frames 302 are fixedly connected to the tops of two arc plates 301. The support frames 302 provide support for the connecting ropes 303, the fixing ropes 304, and the soft flame-retardant cover 4. Two connecting ropes 303 are cross-fixed to the adjacent sides of the two support frames 302. The connecting rope 303 connects the two support frames 302, enhancing the connection stability between them. High-strength nylon rope is used, possessing excellent wear resistance, corrosion resistance, and tensile strength, capable of withstanding significant tension. Multiple fixing ropes 304 are fixedly connected to adjacent sides of the two support frames 302. These fixing ropes 304 connect the support frames 302 and the connecting buckle 305, providing fixing points for the soft flame-retardant cover 4. High-strength nylon rope is used to ensure its strength and stability. When fixed to the support frames 302, the fixing angle has a certain degree of inclination, ensuring the soft flame-retardant cover 4 folds in an orderly manner. The fixed rope 304 is externally fixed with a connecting buckle 305, which is used to connect the fixed rope 304 and the soft flame-retardant cover 4. The tops of the two support frames 302 on opposite sides of the top of the base plate 1 are each fixedly connected with a movable shaft 306. The movable shaft 306 provides a rotational support point for the support column 307, allowing the support column 307 to rotate around the movable shaft 306. Two support columns 307 are externally rotatably connected to the movable shaft 306. The support columns 307 support the rigid flame-retardant cover 5 and cooperate with the fixed column 308 to ensure the structural stability of the rigid flame-retardant cover 5. The two support columns 307 are close to each other. Two fixing posts 308 are cross-fixed on one side, which enhance the connection stability between the support posts 307. The bottoms of multiple support posts 307 are fixedly connected to the top of the fixing base 201. Multiple connecting buckles 305 are externally fixedly connected to a soft flame-retardant cover 4, which covers the goods and serves as a flame retardant. At the same time, it can be deformed according to the shape and size of the goods to better fit them. The support posts 307 and fixing posts 308 are externally fixedly connected to a hard flame-retardant cover 5, which provides additional high-strength protection and flame retardant guarantee for the goods.

[0038] Work steps

[0039] Step 1: After assembling the goods on top of the base plate 1, the entire flame-retardant cover is secured to the base plate 1 by a fixing seat 201 on one side. The fixing seat 201, through its internal slot 202 and movable slot 203, cooperates with the base plate 1 and the sliding latch 204, causing the base plate 1 to press the sliding latch 204 to slide inside the slot 202. This causes the spring 2010 to extend and retract outward, pushing the limiting slider 205 out from the bottom of the sliding latch 204, locking the sliding latch 204 and fixing it inside the slot 202. This forms a latch between the sliding latch 204 and the fixing seat 201, securing the flame-retardant cover to the base plate 1. By pressing the control slider 206, the limiting slider 205 moves in the opposite direction, compressing the spring 2010, causing the sliding latch 204 to slide and release the flame-retardant cover, thus completing the loading and unloading operation.

[0040] Step 2: After the loading and unloading mechanism 2 at the bottom of the support column 307 on one side of the flame-retardant cover is fixed, the bottom of the arc plate 301 is clamped onto the top of the base plate 1. When an external force is applied to the arc plate 301, the arc plate 301 slides on the base plate 1, and the support frame 302 moves accordingly. When the support frame 302 moves, the connecting rope 303 will stretch and contract with the movement of the support frame 302, while maintaining the relative position between the support frames 302. Through the connecting buckle 305 on the fixing rope 304, the soft flame-retardant cover 4 can be tightly connected to the support frame 302. As the extension mechanism 3 unfolds and contracts, it covers and exposes the goods. The support column 307 on the other side rotates around the movable shaft 306, driving the hard flame-retardant cover 5 and the loading and unloading mechanism 2 at the bottom to rotate upward to facilitate covering and exposing the goods. After the covering is completed, it rotates downward to fix the loading and unloading mechanism 2, thereby ensuring the overall structural stability of the flame-retardant cover.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
