[0024] like Figure 1 and Figure 3 As shown, the folding lifting unit includes a top support frame 11, which is a rectangular frame. A second cross frame 6 is hinged on one side of the top support frame 11 close to the front beam. Position adjustment slides 9 are respectively connected to the bottoms of both sides in the length direction of the top support frame 11. A cross frame slide groove is provided in the middle of the position adjustment slide 9. A plurality of blind holes are evenly provided on the surface of the cross frame slide groove along the length direction. Steel balls are provided in the blind holes, and springs are provided between the steel balls and the bottoms of the blind holes.

[0025] The folding lifting unit also includes a first cross frame 12, which passes through the two position adjustment slide plates 9 and is slidably connected thereto. The middle of the first cross frame 12 is rotatably connected to the middle of the second cross frame 6 through a rotating shaft. The second cross frame 6 and the first cross frame 12 are in an X-shaped cross shape, and the intersection is fixed by screws. The first cross frame 12 is rotatably connected to the front beam, and the two ends of the second cross frame 6 are rotatably connected to one end of the rack slider 5.

[0026] like Figure 1-2 As shown, the transmission unit includes a foot pedal 1, one end of the foot pedal 1 is fixedly connected to a pressure rod 17, the pressure rod 17 passes through the rectangular through hole of the fixed shaft 8, the pressure rod 17 is hinged to the fixed shaft 8, and the other end of the pressure rod 17 is connected to a slide rod 18.

[0028] The pedal-type lifting and folding outdoor trolley provided by the utility model has the following working principles:

[0029] The user can use the foot pedal 1 to step down, and the pressure rod 17 rotates to transmit the force to the round-head transmission rod 3. The round-head transmission rod 3 can convert the up and down force of the foot pedal 1 into a rotational force and transmit it to the first gear shaft 14 and then to the first gear 15. The first gear 15 is meshed with the second gear 4 so that the second gear 4 rotates, wherein the first gear 15 is a small gear and the second gear 4 is a large gear. The small gear with the large gear is more labor-saving. The second gear 4 is meshed with the rack slider 5. The rotation of the second gear 4 can make the rack slider 5 slide on the rack slide groove. Since the second cross frame 6 is connected to the rack slider 5, the sliding of the rack slider 5 can make the second cross frame 6 move up and down. The second cross frame 6 intersects with the first cross frame 12. The lifting movement of the second cross frame 6 can also make the first cross frame 12 move up and down. When the first cross frame 12 is lifted or lowered, the upper end is stuck in the cross frame slide slot of the position adjustment slide. Due to the limit of the spring and the steel ball, it can stay at the current height. If it needs to be raised further, it is necessary to step on the pedal 1 to cross the current steel ball. When it needs to be folded, it is only necessary to push the part of the first cross frame 12 in the position adjustment slide 9 to the other end to fold it. The pull rod 2 can also be put down for folding. The final folded shape is as follows: Figure 4 shown.
