[0032] Embodiment 1

[0033] Refer to Figure 1 and Figure 2, an embodiment provided by the present utility model: an unloading slide rail inside an air cargo hold, including a rail body 1. The rail body 1 is the main framework of the entire system, providing structural support and connection functions. The air cylinder 6 is located at the bottom of the inner wall of the rail body 1 and is responsible for generating power to drive the movement of other components. The telescopic rod is fixed to the rear side of the air cylinder and can be telescoped back and forth under the action of the air cylinder, connecting the fixed column to ensure the stability and flexibility of the entire structure. A sliding rod 25 is slidably connected inside multiple fixed columns. Multiple tooth grooves are provided at the top of the latter, allowing it to mesh with the gears of other components. Multiple fixed blocks three at the bottom of the inner wall of the rail body 1 play a role in support and positioning. The entry rail block 2 is fixedly connected to the front side of the rail body 1, and its design purpose is to guide the entry and exit of the sliding rod 25 to ensure the smooth loading and unloading of goods. Multiple support rods one 22 and support rods two 24 are detachably connected to the inner wall of the rail body 1 to provide additional support and stability. Fixed to the far sides of two rotating rods are gears one 26. One of the gears meshes with the top of the sliding rod 25, and the other gear meshes with the rear side of the support rod two 24. The slide rails 3 fixedly connected to the left and right sides of the rail body 1 play a role in guiding and supporting to ensure the smooth movement of the sliding rod and the attached goods. Fixed inside the dust suction blocks 4 fixedly connected to the far sides of the two slide rails 3 is a dust removal component.

[0034] Embodiment Two

[0035] Refer to Figures 1 to 3 , the vacuum cleaner 11 is the core of the entire component and is responsible for generating negative pressure to suck in dust and debris. The suction pipe 5 is fixedly connected to the front side of the vacuum cleaner. Fixed to the inner wall of the dust suction block 4 is a motor two 12. The main function of the motor two 12 is to provide power to make the rotating rod rotate, thereby driving the movement of subsequent mechanical components. The rotation of the rotating rod is transmitted to other connected components through the fixed block one 13 to promote the overall movement. The role of the fixed block one 13 is to stabilize the connection of the rotating rod, and the connecting column 14 serves as a support structure to connect the rotating rod with the subsequent sliding component. The design of the slider allows it to move freely within the limit groove 16, thereby achieving precise mechanical movement. The design of the limit groove 16 ensures that the slider moves within a specific range to avoid damage to the component caused by excessive or insufficient movement. Fixed to the bottom of the fixed block two 18 is a support column 17. The support column 17 is used to enhance the stability of the entire structure to ensure that the component does not shift due to vibration or other factors during operation. Fixed inside the connecting block 19 is the suction pipe 5. This design allows the connection and disconnection of the suction pipe at different positions, facilitating the user to replace cleaning tools or perform maintenance.

[0036] Embodiment Three

[0037] Refer to Figures 2 to 4, another gear 26 meshes with the support rod 22 to achieve the transmission of rotational motion. The support rod 22 serves as the main support structure, bearing the power from the first gear and transmitting it to the components above. The support rod 24 provides additional support to ensure the stability of the entire structure. The connecting rod 20 connects the top of the support rod 24 and the first support platform 8, providing stable support on both sides so that the motion components on both sides can maintain synchronous motion. The first support platform 8 serves as the foundation for multiple moving blocks and is fixedly connected with the first moving block and the third moving block, playing a role of bearing and connecting. The first moving block is connected with the first rotating column 7 to achieve the conversion of rotational motion. The first rotating column 7 is rotatably connected to the first moving block inside and is connected with multiple pulleys outside. The third moving block is similar to the first moving block and is connected with the third rotating column 23 to achieve motion in different directions. The second support platform 21 is fixedly connected with the support rod 22 to provide support for the second moving block. The second rotating column 10 is rotatably connected inside the second moving block to achieve independent rotational motion. The third rotating column 23 is connected with the third moving block and is fixedly provided with multiple pulleys outside. The first motor 9 drives the rotating rod and the rotating column to provide power for the entire device. The first rail body 1 serves as the basic framework of the entire device, providing stable support and guidance.

[0038] Working steps

[0039] Step 1: When in use, the goods rack enters the cabin through the entry rail block 2. When it enters the rail body 1, it automatically stops through the induction device. At this time, the pneumatic cylinder 6 drives the sliding rod 25 to expand and contract. Through meshing, the left gear 26 rotates, and then drives the right gear 26 to rotate. Through meshing, it drives the support rod 22 and the support rod 24 to move in opposite directions. When the goods rack stops on the rail body 1, at this time, the first moving block, the second moving block, and the third moving block all move up and down simultaneously. By controlling the motor 9, it drives the rotating column inside the moving block to rotate, so as to achieve the effect of moving the goods rack inward.

[0040] Step 2: When dust removal is carried out, the second motor 12 drives the rotating rod, drives the connecting column 14 through the first fixing block 13, and thus drives the slider 15 to rotate in the limiting groove 16. The top of the support column 17 is connected with the second fixing block 18. The right side of the second fixing block 18 is rotatably connected with the second rotating rod. The limiting groove 16 rotates through the second rotating rod at the rear side. The slider 15 makes a reciprocating motion with respect to the second rotating rod through the limiting groove 16, so as to make the connecting block 19 move left and right, and thus drive the dust removal pipe 5 to be adjusted left and right, so as to achieve a good dust removal effect, effectively remove dust, debris, and sundries on the slide rail, and keep the cargo hold environment clean.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
