Description

Technical Field

[0001] The utility model relates to the field of arresting devices, in particular to a gravity arresting device in an aviation cargo cabin. Background Art

[0002] An air cargo hold gravity arrester is a system used to stabilize cargo during takeoff and landing. It's designed to prevent cargo from shifting during landing, potentially damaging the aircraft's structure or affecting its balance. This system is particularly important in military and specialty aviation applications, which often carry high-value or sensitive cargo.

[0003] After searching, the Chinese patent document announcement number: CN220284756U discloses a river channel pollution interception device for environmental engineering. In the utility model, it includes a fixed placement seat, and the two sides of the upper end of the fixed placement seat are fixedly connected with side fixed seats. The relative inner sides of the side fixed seats are provided with a preliminary pollution interception structure and a collection device. The preliminary pollution interception structure includes a side mounting plate 1, a connecting plate 1, a large-pore filter anti-collision frame and a latch hole 1. The collection device includes a connecting plate 2, a side mounting plate 2, a medium-pore filter net, a collection net and a limiting latch 2. The gravity of the fixed placement seat and the side fixed seat facilitates the placement of the device. The garbage in the river channel can be preliminarily blocked by the large-pore filter anti-collision frame, and the collection net can collect the garbage in the river channel. Through the cooperation of the above structures, the pollution interception net can be protected while intercepting the river channel.

[0004] However, in this technical solution, "the gravity of the fixed placement seat and the side fixed seat is used to facilitate the placement of the device, and the garbage in the river channel can be initially blocked by the large-pore filtering anti-collision frame." It is difficult to quickly retract and deploy the protective net in the existing technology. In an emergency, such as when it is necessary to quickly unload cargo or respond to emergencies, the inability to quickly retract and deploy the protective net will delay processing time and increase risks. Rapid loading and unloading of cargo is one of the key requirements of air cargo transportation. The inability to quickly retract and deploy the protective net will slow down the loading and unloading speed and affect the flight turnover efficiency. For this reason, a gravity blocking device in the air cargo cabin is proposed to solve the above problems. Utility Model Content

In an emergency, when it is necessary to quickly unload cargo or respond to emergencies, the rapid retraction and extension of the protective net will reduce processing time and reduce risks. Rapid loading and unloading of cargo is one of the key requirements of air cargo. The rapid retraction and extension of the protective net effectively speeds up the loading and unloading speed and reduces the impact on the flight turnover efficiency.

[0032] Example 1

[0033] like Figure 1 As shown, this embodiment provides a gravity arresting device in an air cargo hold, including a cargo hold 1, with a storage box 2 fixedly connected to the top inner wall of the cargo hold 1. The storage box 2 is not only used to integrate equipment, but also carries a motor 3 and other key mechanical structures. When not in use, it can be hidden, reducing interference with items in the cargo hold 1 and improving space utilization and overall aesthetics. A connecting component for fixing is provided at the bottom end of the cargo hold 1. The right side of the storage box 2 is fixedly connected to a motor 3, and the driving end of the motor 3 is fixedly connected to a rotating column 4. The rotating column 4 serves as the core component for power transmission, and its outer wall is evenly distributed with fixed edges 5. These fixed edges 5 are tightly combined with the barrier net 6 to ensure that the net can be unfolded or folded as the motor 3 is started.

[0034] The outer wall of the rotating column 4 is fixedly connected to a fixed edge 5, and the inner wall of the fixed edge 5 is fixedly connected to a blocking net 6. The blocking net 6 is supported by the fixed edge 5 and is located inside the cargo hold 1. It can be quickly opened when necessary to form a stable barrier, effectively preventing the cargo from rushing forward under violent movement. The bottom of the cargo hold 1 is fixedly connected to multiple gravity components for blocking. The connecting components include multiple hooks 7, the top ends of the hooks 7 are fixedly connected to the bottom of the blocking net 6, and the bottom inner wall of the cargo hold 1 is provided with multiple square openings 8.

[0035] Example 2

[0036] like Figures 2 to 4 As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0037] The gravity assembly includes multiple shells 9, the top of which is fixedly connected to the bottom of the cargo hold 1. A sliding block 10 is slidably connected to the inner wall of the shell 9. Shells 9 serve as the main structure of the gravity assembly, with their tops fixedly connected to the bottom of the cargo hold 1, providing stable support for the entire assembly. Shells 9 not only protect the internal mechanism from interference from the external environment but also ensure the precise operation of the mechanism. A rack block 11 is fixedly connected to the right side of the sliding block 10. The outer wall of rack block 11 is slidably connected to the inner wall of slot 16, and the outer wall of rack block 11 is slidably connected to the right inner wall of fixed block 14.

[0038] Two tension springs 12 are fixedly connected to the inner wall of the bottom end of the sliding block 10. A telescopic column 13 is slidably connected to the inner wall of the tension spring 12. The bottom end of the sliding block 10 houses two tension springs 12, which are connected to the telescopic column 13. The top end of the telescopic column 13 is fixed to the bottom end of the fixed block 14, while the bottom end is fixed to the inner wall of the bottom end of the sliding block 10. This design ensures the system's elastic recovery capability, allowing the sliding block 10 to slide smoothly along the inner wall of the housing 9 when subjected to force and then return to its original position under the elastic force of the tension spring 12. The top end of the telescopic column 13 is fixedly connected to the bottom end of the fixed block 14, and the bottom end of the telescopic column 13 is fixedly connected to the inner wall of the bottom end of the sliding block 10. The inner wall of the top end of the sliding block 10 is fixedly connected to the fixed block 14, and the inner wall of the sliding block 10 is fixedly connected to a gear 15. The outer wall of the gear 15 meshes with the outer wall of the rack block 11, forming an efficient power conversion mechanism.

[0039] The outer wall of gear 15 meshes with the outer wall of fixed block 14. The gravity assembly includes a notch 16, which is located on the right inner wall of fixed block 14. Notch 16 not only provides a track for the sliding of rack block 11 but also meshes with the outer wall of gear 15, ensuring smooth power transmission. A weight 17 is fixedly connected to the bottom of sliding block 10. Its weight causes sliding block 10 to naturally fall to the bottom of housing 9 when not affected by other forces, ensuring the initial state of the assembly and the response speed of the gravity assembly. Multiple guide blocks 18 are fixedly connected to the left and right sides of housing 9. Sliding cables 19 are slidably connected to the inner walls of guide blocks 18. Guide blocks 18 not only guide the movement of sliding cables 19 but also ensure stability and guidance during movement, preventing them from deflecting under the action of gravity. The bottom end of sliding cables 19 is fixedly connected to a limit block 20, and the top of sliding cables 19 is fixedly connected to a fixing ring 21.

[0040] Working steps

[0041] In step 1, the rotating shaft of motor 3 begins to rotate, directly driving the rotation of the rotating column 4, which is fixed to it. Serving as the first link in the energy transfer process, rotating column 4 receives the powerful torque from motor 3 and transmits it vertically. As rotating column 4 rotates, the fixed edge 5 surrounding its outer wall also rotates. Not only does the fixed edge 5 rotate synchronously with the rotating column 4, but its unique shape and structure also enable more effective interaction with the subsequent component, the barrier net 6. The rotation of the fixed edge 5 directly affects the barrier net 6 through the physical connection between the two. Under the influence of the rotational force, the barrier net 6 begins to transition from a static state to a dynamic retractable mode. The essence of this design lies in how to achieve precise control using simple mechanical principles. The retraction and extension of the barrier net 6 is entirely dependent on the rotational rhythm and amplitude of the fixed edge 5. When the fixed edge 5 rotates in the forward direction, the barrier net 6 gradually deploys, and vice versa, it gradually retracts. This ingenious mechanism ensures that the barrier net 6 can quickly cover or open the entire cargo hold 1 area according to actual needs, greatly improving the flexibility and efficiency of security management within the air cargo hold.

[0042] Step 2: When the cargo slides abnormally under sudden circumstances and violently hits the barrier net 6, this event immediately becomes the starting point for triggering the entire response mechanism. The sudden force on the barrier net 6 will be directly transmitted to the multiple hooks 7 connected to its bottom. These hooks 7 then pull the fixed ring 21, starting the first link of the chain reaction. The movable design of the fixed ring 21 enables it to respond quickly to changes in external forces. The movement of the fixed ring 21 will directly pull the sliding steel cable 19 connected to it. Under the restriction of the limit block 20, the sliding steel cable 19 can only move along the predetermined path, thereby ensuring the directionality and continuity of the force. As the sliding steel cable 19 is pulled, the limit block 20 moves downward, and the force is smoothly transmitted to the sliding block 10 at the bottom through the guidance of the guide block 18. The position setting of the two guide blocks 18 at the bottom ensures the smoothness and precision of this process. While the sliding block 10 moves in the guide rail, the rack block 11 connected to it also begins to slide along the fixed track. This action breaks the original static balance and lays the foundation for the next step of energy conversion. The linear motion of rack block 11 is converted into rotational motion of gear 15. This rotation causes sliding on fixed block 14, directly triggering the extension and retraction of tension spring 12 and telescopic column 13. This design cleverly converts linear force into rotational force, and then into retraction and extension power. During the system's response, if an additional weight 17 is attached, its presence significantly increases the overall weight, thereby amplifying the original force effect and providing stronger gravity support for the entire blocking and locking process.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
