[0037] Specifically, such as Figure 7 As shown: Multiple limiting plates 611 can be moved out of the hollow column 605 through the interior of multiple limiting slots 612, and multiple limiting plates 611 can be inserted into the interior of multiple limiting slots 613, cooperating with the tension of the first spring 608 to limit the resetting of the pull rod 609.

[0038] In one embodiment, the adjusting component 9 includes a plurality of limiting holes 901, which are uniformly and correspondingly opened through the other side surface of the two sliding plates 701. Two long rods 902 are fixedly installed between the opposite side surfaces of the two hollow long plates 7.

Two second springs 904 are fixedly installed between one side surface of the two movable plates 903 and one side surface of the two hollow long plates 7. The two ends of the two long rods 902 are located inside the plurality of second springs 904.

[0040] In one embodiment, limit rods 905 are fixedly installed on one side surface of both movable plates 903. The two limit rods 905 correspondingly pass through one side surface of the two hollow long plates 7 and correspondingly pass through the interior of the two limit holes 901.

[0041] Specifically, such asFigure 4 As shown: The two limiting rods 905, together with the multiple limiting holes 901, can limit the position of the two sliding plates 701 inside the two hollow long plates 7.

[0042] In one embodiment, an L-shaped plate 906 is fixedly installed on the other side surface of each of the two movable plates 903, and a connecting rod 907 is fixedly installed on the upper and lower sides of each of the two L-shaped plates 906. A ring 908 is fixedly installed on one end surface of each of the multiple connecting rods 907, and the multiple rings 908 are correspondingly and movably fitted onto the outer wall surface of the two long rods 902.

[0043] Specifically, such as Figure 9 As shown: The two L-shaped plates 906 are designed so that passengers can pull the two L-shaped plates 906 with one hand to adjust the position of the two limit rods 905.

[0044] Working principle:

[0045] When using the airport trolley, the entire device can be moved using the U-shaped pull rod 702 and multiple casters 2. When it is necessary to reduce the space occupied by the airport trolley, first pull the two pull rings 610. The movement of the two pull rings 610 drives the two pull rods 609 to move. The movement of the two pull rods 609 drives the two discs 606 to move. The movement of the two discs 606 stretches the two first springs 608, thus causing the two first springs 608 to be stretched. The movement of the two pull rods 609 simultaneously drives the multiple limit plates 611 to move. The multiple limit plates 611 move from the inside of the corresponding multiple limit slots 612. The two hollow columns 605 are inserted into the interior, and then the two rotating rods 4 are rotated. The rotation of the two rotating rods 4 drives the multiple limiting plates 611 to rotate. When the multiple limiting plates 611 rotate to one side of the multiple limiting grooves 613, the two pull rings 610 are released. Using the rebound force of the two first springs 608, the multiple limiting plates 611 are inserted into the multiple limiting grooves 613, thereby restricting the movement of the two insert rods 607. At the same time, the movement of the two discs 606 drives the movement of the two insert rods 607, thereby causing the two insert rods 607 to move out of the interior of the two through holes 603, thus releasing the rotation of the rotating rods 4.

[0046] At this point, the two hollow long plates 7 are rotated, which drives the cylinder 5 to rotate. The rotation of the cylinder 5 drives the multiple short plates 602 to rotate. When the hollow long plates 7 are completely inside the groove 3, the other two short plates 602 are moved out from inside the two rectangular slots 601. Then, the two pull rings 610 are pulled and rotated again, so that the multiple extension plates 704 are placed inside the two hollow columns 605 again. The rebound force of the two first springs 608 is used to make the two insert rods 607 re-inserted into the corresponding two through holes 603, thereby restricting the two hollow long plates 7 inside the groove 3, thus completing the purpose of folding the airport trolley.

[0047] With the cooperation of the above structures, the two hollow long plates 7, the two sliding plates 701 and the U-shaped pull rod 702 can be folded inside the groove 3, so that the airport trolley can be folded, reducing the space occupied, facilitating the transportation, storage and carrying of the airport trolley, and demonstrating the portability of the airport trolley.

[0048] When the height of the U-shaped pull rod 702 needs to be adjusted, first pull the two L-shaped plates 906, causing them to move closer to each other. This movement of the L-shaped plates 906 drives multiple connecting rods 907 to move, which in turn moves multiple rings 908 across the surfaces of the two long rods 902. Simultaneously, the movement of the L-shaped plates 906 causes two movable plates 903 to move closer to each other. This movement of the movable plates 903 stretches multiple second springs 904, causing them to compress. At the same time, the movement of the movable plates 903 also drives two limiting rods 905 to move, causing the limiting rods 905 to move from their respective positions. The two limiting holes 901 are moved out, so that the two sliding plates 701 are no longer limited inside the two hollow long plates 7. At this time, the U-shaped pull rod 702 is pulled upward. The movement of the U-shaped pull rod 702 drives the two sliding plates 701 to move. The movement of the two sliding plates 701 drives the multiple extension plates 704 to slide inside the corresponding multiple long slots 703. When the U-shaped pull rod 702 moves to the appropriate height, the two L-shaped plates 906 are then released. The rebound force of the multiple second springs 904 causes the two limiting rods 905 to be re-inserted into the corresponding two limiting holes 901, thereby limiting the movement of the two sliding plates 701 and thus completing the purpose of adjusting the height of the U-shaped pull rod 702.

[0049] With the combination of the above structures, the height of the U-shaped pull rod 702 can be adjusted by the two limiting rods 905 and the multiple limiting holes 901, so that the airport trolley can be adapted to passengers of different heights, demonstrating the multi-functionality of the airport trolley.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
