Detailed Implementation

[0024] The specific solutions and embodiments of this utility model will be further described in conjunction with the accompanying drawings, making the technical solution clearer and more understandable.

[0025] Example 1

[0026] like Figures 1-4 As shown, a sliding, non-rising trolley includes a bottom folding frame 1, a front folding frame 2a, a rear folding frame 2b, two side folding frames 2, and four support rods 3 with rollers 6 at their bottoms. The support rods 3 have upper connecting seats 4 and lower connecting seats 5 at their upper and lower ends, respectively, and are distributed at four corners. The front folding frame 2a, rear folding frame 2b, and two side folding frames 2 are respectively installed between two support rods 3. The upper ends of the side folding frames 2 are movably riveted to the two upper connecting seats 4, and their lower ends are slidably connected to the support rods 3 via sliders 8. The front folding frame 2a and rear folding frame 2b include two movably riveted crossbars 21 (each crossbar 21 includes two cross-shaped, movably riveted sidebars), their upper ends are slidably connected to the support rods 3 via sliders 8, and their lower ends are movably riveted to the lower connecting seats 5.

[0027] The side folding frame 2 includes a hanging rod 5 and two pairs of cross rods 21. The upper and lower ends of the hanging rod 5 are respectively provided with an upper fixed seat 9 and a lower fixed seat 10, and the hanging rod 5 is provided with a sliding seat 11 that can slide up and down. On both sides of the hanging rod 5, a pair of cross rods 21 are provided and riveted together. The upper and lower ends of the inner side of the cross rod 21 are riveted to the upper fixed seat 9 and the sliding seat 11, respectively, and the upper end of the outer side is riveted to the upper connecting seat 4, and the lower end is slidably connected to the support rod 3 through a slider 8. The bottom folding frame 12 includes two base frames, and the inner and outer sides of the base frames are riveted to the lower fixed seat 10 and the lower connecting seat 5, respectively.

[0028] In this embodiment, the front folding frame 2a, the rear folding frame 2b, and the two side folding frames 2 are each riveted to the slider 8. When folding, the slider 8 is used to slide up and down to realize the unfolding and retraction of the crossbar 21.

[0029] In this embodiment, the slider 8 has an arc-shaped structure. One side has an opening that fits onto the support rod 3 and can slide up and down. The other side has a slot that is movably riveted to the upper or lower end of the cross rod 21.

[0030] The base frame includes a central seat 11 and four base rods 12 that are movably riveted to the four corners of the central seat. The outer base rods 12 are movably riveted to the lower connecting seat 5, and the inner base rods 12 are movably riveted to the lower fixed seat 9.

[0031] The center seat 11 has mounting grooves at its four corners that extend from the lower surface to the sides. The bottom rods 12 are riveted together after being inserted into the mounting grooves. When folded, the four bottom rods 11 rotate and converge towards the bottom of the center seat 11.

[0032] The trolley also includes a pull rod 14, which includes a handle 141, an upper rod 142, a pull rod seat 143, and two lower rods 144. The upper rod 142 is slidably connected to the pull rod seat 143, and the handle 141 is provided at the top of the upper rod 142. The two lower rods 144, which are symmetrically arranged on the left and right, are movably riveted to the pull rod seat 143 and can rotate in the left and right directions to achieve trolley folding or opening. The lower end of the lower rod is movably riveted to the lower connecting seat 5.

[0033] The pull rod 14 also includes a connecting block 145. The lower end of the lower rod 144 is movably riveted to the connecting block 145 and can rotate left and right. The connecting block 145 is movably riveted to the lower connecting seat 5 and can rotate back and forth.

[0034] The upper rod 142 is a telescopic rod. By extending and retracting, it adapts to the needs of users of different heights, improving the convenience of using the stroller.

[0035] The rollers on the two front support rods 3 are omnidirectional wheels with brakes, while the rollers on the two rear support rods 3 are directional wheels.

[0036] Example 2

[0037] Unlike Example 1, such as Figure 5 As shown, the folding trolley of this embodiment includes a front folding frame 2a, two side folding frames 2, and no rear folding frame. A foldable lower crossbar 12 is provided between the two lower connecting seats 5 on the rear side. The lower crossbar 12 includes two short rods 121 and a connector 122, with both ends of the connector 122 being movably riveted to the two short rods 121 respectively. When folded, the two short rods 121 rotate downwards towards the connector 122 to fold together.

[0038] Example 3

[0039] Unlike Example 1, as Figure 6As shown, the front folding frame 2a and the rear folding frame 2b of the folding cart of the embodiment are both provided with two movable cross rods 21. The upper end of the front folding frame 2a is movably riveted to the upper connecting seat 4, and the lower end is movably riveted to the sliding block 8, which is slidably connected to the supporting rod 3 and can slide up and down. The upper end of the rear folding frame 2b is slidably connected to the supporting rod 3 through the sliding block 8 and can slide up and down, and the lower end is movably riveted to the lower connecting seat 5.

[0040] The front folding frame 2a and the side folding frame 2 of the embodiment are movably riveted to the same sliding block 8, and the sliding block 8 slides up and down along the supporting rod 3 when folding, and the cross rod 21 is unfolded or folded.
