Principles of the utility model

Before the trolley is transported and carried, the locking bolt 3 is removed, so that the sliding column 5 slides downwards in the groove 12 until reaching the bottommost part of the groove 12; therefore, the upper placing frame 4 also slides downwards along the sliding column 5, the overall trolley is low in height, and then the locking bolt 3 is used for fixedly connecting the fixed column 2 with the sliding column 5 again; therefore, the space in the vertical direction occupied by the cart is reduced, and the cart is more convenient to transport; and because the whole height of the trolley descends, the gravity center of the trolley also descends along with the whole height of the trolley, and thus the whole trolley structure is more stable.

The stud 10 is removed, the operation block 8 is operated, and the connecting plate 17 drives the wheel structure 18 to move upwards until the wheel structure 18 is completely positioned in the placing cylinder 9; pulling the plunger 15 away from the placement cylinder 9 while the retaining ring 19 compresses the compression spring 14; aligning the insert rod 15 with the insertion hole 16, loosening the insert rod 15, and allowing the insert rod 15 to be inserted into the insertion hole 16 under the resilience force of the compression spring 14, thereby preventing the wheel structure 18 from falling from the placement barrel 9; the compression spring 14 reserves a certain compression amount during installation, so that the compression spring 14 continuously generates pressure on the fixed ring 19, and the inserted link 15 is not easy to disengage from the jack 16. At this time, the wheel structure 18 is retracted in the placement cylinder 9, so that the problem that the cart is very unstable during transportation and is easy to move randomly due to slight shock caused by the existence of the wheel structure 18 can be solved.

The utility model and its embodiments have been described above with no limitation, and the actual construction is not limited to the embodiments of the utility model as shown in the drawings. In summary, if one of ordinary skill in the art is informed by this disclosure, a structural manner and an embodiment similar to the technical solution should not be creatively devised without departing from the gist of the present utility model.
