[0015] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0016] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0017] The multi-functional folding trolley includes a base frame 1, a handrail frame 2 at the front end of the base frame 1, a rear frame 3 at the rear end of the base frame 1, the handrail frame 2 and the rear frame 3 are rotatably connected to the base frame, and side frames 4 are provided on both sides of the base frame 1.

[0018] The handrail frame 2 includes a connecting rod 21, a telescopic frame 22, and a handrail 23. The bottom end of the connecting rod 21 is rotatably connected to the base frame 1. The telescopic frame 22 is inserted into the top end of the connecting rod 21 and is slidably connected to the connecting rod 21. The handrail 23 is rotatably connected to the telescopic frame 22.

[0019] The rear end of the base frame 1 is rotatably connected to a fixed frame 5, and both ends of the handrail 23 are rotatably connected to the fixed frame 5. The telescopic frame 22 is provided with buckles 51 that engage with the fixed frame 5. Figure 1 As shown, the handrail 23 is in the unfolded state, with the buckle 51 secured to the fixing frame 5. When the handrail 23 needs to be retracted, the buckle 51 is disengaged from the fixing frame 5, and the handrail 23 is rotated. The telescopic frame 22 gradually inserts into the connecting rod 21 until the handrail 23 is parallel to the telescopic frame 22, thus completing the retraction of the handrail 23. Figure 4 As shown.

[0020] A connecting rod frame 6 is provided on the base frame 1. The bottom end of the connecting rod frame 6 is rotatably connected to the base frame 1, and a slider 7 is provided on the upper end of the connecting rod frame 6. The slider 7 is slidably connected to the connecting rod 21.

[0021] The slider 7 is equipped with a locking component, which includes a positioning rod 8 and a spring 81. The connecting rod 21 has a positioning hole 24. The spring 81 can push the positioning rod 8 into the positioning hole 24. The telescopic frame 22 slides in the connecting rod 21 and can push the positioning rod 8 out of the positioning hole 24 to unlock.

[0022] The rear frame 3 can rotate relative to the base frame 1 to change the tilt angle of the rear frame 3. An angle limiter 9 is provided between the rear frame 3 and the base frame 1 to keep the rear frame 3 from rotating.

[0023] Angle limiter 9 is a straight pull rod.

[0024] Angle limiter 9 is located between side frame 4 and rear frame 3, with both ends of angle limiter 9 hinged to side frame 4 and rear frame 3 respectively.

[0025] In the first state, the handrail frame 2 is perpendicular to the base frame 1, the locking device locks the handrail frame 2, the positioning rod 8 is inserted into the positioning hole 24, the rear frame 3 is perpendicular to the base frame 1, and the straight pull rod is in its shortest state. This is the trolley state. Figure 1 As shown.

[0026] In the second state, the handrail frame 2 is perpendicular to the base frame 1. Rotate the rear frame 3 to make it parallel to the base frame 1. This is the extended trolley state. Figure 5 As shown.

[0027] In the third state, the locking mechanism is unlocked, and the buckle 51 is removed from the fixing frame 5. The armrest 23 is rotated, causing the telescopic frame 22 to slide on the connecting rod 21. The telescopic frame 22 gradually inserts into the connecting rod 21 until the positioning rod 8 is pushed out of the positioning hole 24, thus unlocking the chair. Then, the armrest frame 2 is rotated to be parallel to the base frame 1, and the rear frame 3 is rotated to form an inclined angle with the base frame 1. The straight pull rod is at its middle length. At this time, the chair is in the reclining position. Figure 6 As shown.

[0028] In the fourth state, unlock the locking mechanism, rotate the armrest frame 2 to make it parallel to the base frame 1. As the connecting rod 21 rotates, the slider 7 slides on the connecting rod 21 until the armrest frame 2 is fully extended. Then, the slider 7 slides to the bottom of the connecting rod 21, and the armrest 23 rests on the ground. At this point, the armrest 23 also provides support. Rotate the rear frame 3 to make it parallel to the base frame 1, and the straight lever is at its longest position. This is the reclining position. Figure 7 As shown.

[0029] like Figure 8 The image shows the stroller in its folded state; it is smaller when folded and easier to store.
