[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 6 The utility model provides a foldable shuttle for airport cargo transportation, comprising a support frame 1 and two horizontal plates 2 axially connected to the top of the support frame 1. A plurality of conveying rollers 8 are rotatably connected between the two horizontal plates 2. Luggage and cargo move on the conveying rollers 8 to achieve the purpose of rapid transportation. The support frame 1 is connected to a positioning mechanism for positioning the horizontal plate 2. The positioning mechanism comprises two lifting blocks 9, two positioning blocks 12, and two positioning columns 13. The lifting block 9 is movably connected to the support frame 1. The positioning block 12 and the positioning column 13 are connected to the top of the lifting block 9. The two ends of the horizontal plate 2 are connected to an interface 11 and a joint 14. The interface 11 matches the joint 14. The lifting block 9 is connected to a driving mechanism for driving the lifting block 9 to rise and fall.

[0024] When unfolded for use, the cross plate 2 is perpendicular to the support frame 1, and the rotating handle 4 is rotated to drive the stud 5 to rotate, which can drive the lifting plate 6 to move up, and the lifting plate 6 drives the two lifting blocks 9 to move up synchronously until the positioning block 12 is connected to the socket 16, and the positioning column 13 passes through the positioning hole 10 and is connected to the positioning hole 2 15 of the joint 14, and the lifting block 9 is tightly attached to the bottom of the cross plate 2, and the rotation of the rotating handle 4 is stopped, which can not only lock the cross plate 2 and ensure the stability of the overall structure, but also realize the stable docking of multiple connectors, which is safe and reliable to use.

[0025] When folding, the transverse board 2 is in a loosened state, and the transverse board 2 is driven to rotate 90°. Then the two lifting blocks 9 move up synchronously, so that the positioning block 12 is connected to the corresponding interface 11 to lock the transverse board 2. At this time, the whole is in a vertical state and is not easy to shake, which reduces the space occupied and facilitates subsequent packaging and transportation.

[0026] The interface 11 is provided with a positioning hole 10 matching the positioning column 13, and the positioning hole 10 matches the positioning hole 2 15. When the two connectors are docked, the connector 14 is fully inserted into the corresponding interface 11, the positioning hole 10 and the positioning hole 2 15 are in an aligned state, and the positioning column 13 passes through the positioning hole 10 and is connected to the positioning hole 2 15 of the connector 14, so that the two connectors are connected and fixed.

[0027] A guide groove 17 is provided on the inner side of the support frame 1, and the lifting block 9 is slidably connected to the guide groove 17, which can improve the stability of the lifting block 9 when it is lifted and lowered. When it is in the unfolded state, it is convenient for the positioning block 12, the positioning column 13 to be accurately connected with the corresponding jack 16 and the second positioning hole 15.

[0028] The inner axis of the support frame 1 is connected with a connecting plate 3. When folded, the transverse plate 2 rotates around the d-axis, and the connecting plate 3 rotates around the c-axis.

[0029] The driving mechanism includes a rotating handle 4, a stud 5, a lifting plate 6, and a fixed plate 7. Both ends of the fixed plate 7 are fixed to the support frame 1. The rotating handle 4 is used to drive the stud 5 to rotate, and the stud 5 is used to drive the lifting plate 6 to rise and fall. One end of the stud 5 is rotatably connected to the fixed plate 7, and both ends of the lifting plate 6 are connected to two lifting blocks 9. The fixed plate 7 can improve the stability of the rotation of the stud 5. Manually driving the rotating handle 4 to rotate can drive the stud 5 to rotate, which is convenient for lifting and lowering the lifting plate 6, thereby realizing the synchronous lifting and lowering of the two lifting blocks 9, and the operation is simple and convenient.

[0030] The rotating handle 4 is connected to the other end of the stud 5, and the stud 5 is threadedly connected to the lifting plate 6, and the lifting plate 6 is a U-shaped structure.

[0031] Working principle: In normal use, two adjacent connectors can be docked, so that the connector 14 is inserted into the corresponding interface 11. Rotating the rotating handle 4 drives the stud 5 to rotate, so that the lifting plate 6 moves up, and the lifting plate 6 drives the two lifting blocks 9 to move up synchronously until the positioning block 12 is connected to the jack 16, and the positioning column 13 passes through the positioning hole 10 and is connected to the positioning hole 2 15 of the connector 14, and the lifting block 9 is close to the bottom of the cross plate 2, and the rotation of the rotating handle 4 is stopped. It can not only ensure the stability of the overall structure, but also achieve the purpose of docking the two connectors. The operation is simple and convenient, and the flexibility is high. When folding, first loosen the cross plate 2, then drive the cross plate 2 to rotate 90°, so that the interface 11 is facing downward and aligned with the positioning block 12, and then drive the rotating handle 4 to rotate and drive the two lifting blocks 9 to move up, so that the positioning block 12 is docked with the interface 11, and then the cross plate 2 is locked and fixed. At this time, the whole is in a vertical state, reducing the occupied space and facilitating subsequent packaging and transportation.
