[0025] Example 1 Reference Figure 1 As shown, this embodiment provides a locking structure 200 for a flight hanger 100, including a fixing member 210, a lock body 220, a hanging member 230, and an unlocking member. The fixing member 210 is provided with a mounting hole 211 for connecting to the flight hanger 100.

[0026] Specifically, the lock body 220 is rotatably mounted on the fixing member 210, that is, the lock body 220 is rotatably connected to the fixing member 210 via a pivot 221. The lock body 220 includes a latch end 222 and an unlock end 223, with the latch end 222 extending laterally toward the unlock end 223, thus forming an L-shaped structure. After the lock body 220 is rotatably mounted on the fixing member 210, the latch end 222 is positioned below the unlock end 223.

[0027] Specifically, one end of the hanging component 230 is provided with a buckle body 231 for engaging with the locking end 222. In the locked state, the buckle body 231 engages with the locking end 222, thereby connecting the hanging component 230 to the fixing component 210. The hanging component 230 is used to connect to the container 300, thus allowing the container 300 to be mounted on the flight rack 100 when the locking structure 200 is locked. In this embodiment, the flight rack 100 can be understood as an aircraft capable of connecting to the items to be transported via the locking structure 200.

[0028] Specifically, the unlocking element is used to lock or release the lock body 220. When the unlocking element locks the lock body 220, the latch 231 engages with the latch end 222, keeping the container 300 connected to the flight rack 100; when the unlocking element releases the lock body 220, the lock body 220 rotates, causing the latch 231 to separate from the latch end 222, thus separating the container 300 from the flight rack 100.

[0029] The locking structure 200 of the flight hanger 100 provided in this embodiment, when the unlocking member locks the lock body 220, causes the latch body 231 to engage with the latch end 222, thus limiting the rotation of the lock body 220 and ensuring a stable connection between the hanging member 230 and the lock body 220, enabling the installation of the container 300 and the flight hanger 100. When the unlocking member releases the lock body 220, the hanging member 230, under the weight of the container 300, drives the lock body 220 to rotate, thereby separating the latch body 231 from the latch end 222 and enabling the disassembly of the container 300 and the flight hanger 100. This locking structure 200 enables the rapid installation and disassembly of the container 300 and the flight hanger, improving transportation efficiency. Moreover, the overall locking structure 200 is simple and can conveniently realize the installation and disassembly of the container 300 and the flight hanger.

[0030] Specifically, the locking end 222 protrudes along one side of the unlocking end 223 to form a first locking surface, and the buckle body 231 protrudes along one side of the hanging member 230 to form a second locking surface. When the buckle body 231 is engaged with the locking end 222, the second locking surface abuts against the first locking surface and the buckle body 231 is positioned above the locking end 222. When the unlocking member releases the lock body 220, under the gravity of the container 300, the lock body 220 rotates around the pivot 221, the first locking surface rotates to an inclined state, and the second locking surface can move smoothly relative to the first locking surface, thereby separating the hanging member 230 from the lock body 220.

[0031] It should be noted that there are various forms of unlocking devices; in this embodiment, an electromagnetic unlocking device is provided. (Continue to refer to...) Figure 1 As shown, the unlocking component includes an electromagnet 240, with the unlocking end 223 made of ferromagnetic material. The electromagnet 240 and the hanging component 230 are located on opposite sides of the lock body 220. When the electromagnet 240 is energized, it attracts the unlocking end 223, restricting the rotation of the lock body 220. At this time, the lock body 220 is in a vertical state, maintaining the engagement between the latch body 231 and the latch end 222, thereby keeping the container 300 and the flight rack 100 connected. (Refer to...) Figure 2 As shown, when the electromagnet 240 is de-energized, the unlocking end 223 is released, allowing the unlocking end 223 to rotate freely. At this time, under the gravity of the container 300, the lock body 220 is driven to rotate around the pivot 221, causing the lock body 220 to be in an inclined state, thereby allowing the latch body 231 to disengage from the latch end 222. (Refer to...) Figure 3 As shown, when the fastener 231 disengages from the locking end 222, the lifting component 230 continues to move downward, thereby separating the container 300 from the flight rack 100.

[0032] Specifically, refer to Figure 4As shown, the flight rack 100 is connected to multiple fasteners 210, each fastener 210 is provided with a lock body 220, and the container 300 is connected to multiple hanging parts 230. The relative positions of each hanging part 230 are fixed, and each hanging part 230 corresponds one-to-one with each lock body 220, so that the horizontal position of each hanging part 230 is relatively fixed, and the hanging part 230 can only be moved in the vertical direction to achieve the engagement or disengagement between the hanging part 230 and the lock body 220.

[0033] Usage process: During flight transport, the fastener 210 is installed on the flight hangar, and the suspender 230 is connected to the container 300. The electromagnet 240 attracts the unlocking end 223 to keep the lock body 220 in a vertical downward position, restricts the rotation of the lock body 220, and makes the buckle 231 engage with the locking end 222, thereby making the container 300 stably connected to the flight hangar 100.

[0034] When it is necessary to release container 300, electromagnet 240 is de-energized and no longer attracts unlocking end 223, allowing lock body 220 to rotate freely. Due to the weight of container 300, the hanging component 230 will generate a downward force, thereby driving lock body 220 to rotate around pivot 221 and release hanging component 230.

[0035] The lifting component 230 moves downward and separates from the locking body 220, causing the container 300 to detach from the flight rack 100.

[0036] Example 2 Reference Figure 5 As shown, this embodiment provides a locking structure 200 for a flight rack 100. It should be noted that the lock structure 200 provided in this embodiment differs from the lock structure 200 in embodiment 1 in that the structure of the unlocking component is different. In this embodiment, a mechanical unlocking component is provided.

[0037] Reference Figure 5 As shown, the unlocking component includes a movable block 250, and the fixing component 210 is provided with a movable groove 212. The movable block 250 is movably installed in the movable groove 212. The movable groove 212 is divided into a first position and a second position according to its relative position with the unlocking end 223, so that when the movable block 250 moves to the first position, it abuts against the unlocking end 223, and when the movable block 250 moves to the second position, it separates from the unlocking end 223.

[0038] Specifically, the movable groove 212 extends vertically, with the first position located at the lower end of the movable groove 212 and the second position located at the upper end of the movable groove 212. The movable block 250 and the hanging member 230 are respectively located on the same side of the lock body 220, as shown in the figure. Figure 5As shown, when the moving block 250 moves to the lower end of the moving slot 212, the moving block 250 abuts against the unlocking end 223. At this time, the unlocking component and the lock body 220 are in a locked state, restricting the rotation of the lock body 220. The latching body 231 engages with the latching end 222, keeping the container 300 in the installed state with the flight rack. (Refer to...) Figure 6 As shown, when the moving block 250 moves upward to the upper end of the moving groove 212, the moving block 250 separates from the unlocking end 223, and the unlocking component is separated from the lock body 220, no longer restricting the rotation of the lock body 220. Therefore, under the gravity of the container 300, the lock body 220 is driven to rotate around the pivot 221, thereby causing the lock body 220 to tilt. (Refer to...) Figure 7 As shown, the sling 230 continues to move downward, thereby separating the sling 230 from the lock body 220 and removing the container 300 from the flight rack 100.

[0039] It should be noted that the movable block 250 can be moved by a movable structure. Specifically, the movable structure is connected to both the movable block 250 and the fixed member 210, and the movable block 250 is moved and its position changed by the extension and retraction of the movable structure. It should also be noted that the movable structure can be a hydraulic rod, a pneumatic rod, an electric rod, or other types of movable structures.

[0040] Usage process: During flight transport, the fastener 210 is installed on the flight hangar, and the suspender 230 is connected to the container 300; the moving block 250 moves to the lower end of the moving slot 212 and abuts against the unlocking end 223, restricting the rotation of the lock body 220 and engaging the buckle body 231 with the locking end 222, thereby stably connecting the container 300 to the flight hangar 100.

[0041] When it is necessary to release the container 300, the moving block 250 is moved to the upper end of the moving groove 212 and disengaged from the unlocking end 223, and the rotation of the lock body 220 is no longer restricted. Due to the weight of the container 300, the hanging component 230 will generate a downward force, thereby driving the lock body 220 to rotate around the rotating shaft 221 and releasing the hanging component 230.

[0042] The lifting component 230 moves downward and separates from the locking body 220, causing the container 300 to detach from the flight rack 100.

[0043] Example 3 Reference Figure 8 As shown, this embodiment provides a locking structure 200 for a flight rack 100. It should be noted that the lock structure 200 provided in this embodiment differs from the lock structure 200 in embodiment 1 in that the structure of the unlocking component is different. In this embodiment, a pneumatic unlocking component is provided.

[0044] Specifically, refer to Figure 9As shown, the unlocking component includes a piston 260 and a gas generator 270; the fixing component 210 is provided with a piston channel, and the piston 260 is movably installed in the piston channel, allowing the piston 260 to move along the piston channel, and the piston 260 and the hanging component 230 are respectively located on both sides of the lock body 220. An elastic component 213 is provided between the unlocking end 223 and the fixing component 210; the elastic component 213 has elastic potential energy to drive the unlocking end 223 toward the piston 260; the gas generator 270 is connected to the piston channel, so that when the gas generator 270 is activated, it pushes the piston 260 to move toward the direction of the elastic component 213.

[0045] Reference Figure 9 As shown, when the gas generator 270 is not started, the unlocking end 223 remains vertically downward under the elastic potential energy of the elastic element 213. At this time, the unlocking element locks the lock body 220, the buckle body 231 is engaged with the buckle end 222, and the container 300 is installed on the flight rack 100.

[0046] Reference Figure 10 As shown, when the gas generator 270 is started, gas enters the piston channel and pushes the piston 260 towards the direction of the elastic element 213. This causes the piston 260 to push the unlocking end 223 to overcome the elastic potential energy of the elastic element 213 and rotate around the shaft 221, thereby releasing the lock body 220. (Refer to...) Figure 11 As shown, the lifting component 230 continues to move downward, thereby separating the fastener 231 from the locking end 222, and realizing the disassembly of the container 300 from the flight rack 100.

[0047] It should be noted that, continuing to refer to Figure 8 As shown, an outer cover 290 is connected to the outside of the fixing member 210 to close the piston channel.

[0048] Specifically, continue to refer to Figure 11 As shown, the piston channel includes an upper partition 214 and a lower partition 215, with a notch on the lower partition 215. The unlocking end 223 extends into the piston channel through the notch, and the width of the notch is greater than the width of the unlocking end 223. When the gas generator 270 is not activated, the unlocking end 223 abuts against the lower partition 215 under the elastic potential energy of the elastic element 213, keeping the lock body 220 in a vertically downward state. When the piston 260 pushes the unlocking end 223, the lock body 220 can rotate at the notch.

[0049] Specifically, refer to Figure 12As shown, a gas pipeline 280 is arranged on the top of the container 300. Each gas pipeline 280 is connected to a corresponding piston channel. The gas generator 270 is installed on the gas pipeline 280. The gas generated by the gas generator 270 is delivered to each piston channel through the gas pipeline 280, which can keep each locking structure 200 released synchronously.

[0050] Usage process: During air transport, the fastener 210 is installed on the flight hangar, and the suspender 230 is connected to the container 300; the elastic element 213 pushes the unlocking end 223 to make the lock body 220 abut against the lower partition 215, thereby keeping the lock body 220 in a vertical state, restricting the rotation of the lock body 220, and making the buckle 231 engage with the locking end 222, thereby making the container 300 stably connected to the flight hangar 100.

[0051] When container 300 needs to be released, gas generator 270 is activated, allowing gas to enter the piston channel and push piston 260 to move. This causes piston 260 to push unlocking end 223 to overcome the elastic potential energy of elastic element 213 and no longer restrict the rotation of lock body 220. Due to the weight of container 300, the hanging component 230 will generate a downward force, thereby driving lock body 220 to rotate around pivot 221 and release hanging component 230.

[0052] The lifting component 230 moves downward and separates from the locking body 220, causing the container 300 to detach from the flight rack 100.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
