A plurality of arc-shaped plates 3 are fixedly connected to the top of the carrying platform 1. A rotating shaft 14 is rotatably connected between two arc-shaped plates 3. A handle 4 is fixedly connected inside the rotating shaft 14. A sliding column 15 is fixedly connected inside the handle 4. An arc-shaped groove 13 is provided inside the arc-shaped plate 3. A stopper 19 is slidably connected inside the arc-shaped plate 3. A pull rod 17 is fixedly connected to the top of the stopper 19. A spring 18 is sleeved outside the pull rod 17. A blocking component for preventing goods from accidentally falling is arranged on the top of the carrying platform 1. The carrying platform 1 serves as the basic frame of the trolley and is used to place and transport kitchen supplies. The arc-shaped plate 3 is used for fixing the handle 4 and provides a force point for the foldable handle 4. The rotating shaft 14 enables the handle 4 to rotate between two arc-shaped plates 3. The handle 4 is fixedly connected to the rotating shaft 14, providing a grasping point for the operator and facilitating the manual control of the unfolding and folding of the trolley. The stopper 19 is used to control whether the sliding column 15 can slide in the arc-shaped groove 13, thus ensuring the movement of the handle 4. The spring 18 is used to firmly insert the stopper 19 into the arc-shaped groove 13 and abut against the sliding column 15 without external force. The pull rod 17 is used to pull the stopper 19. The arc-shaped groove 13 is provided inside the arc-shaped plate 3 and is used to guide the movement of the sliding column 15.
[0035] Referring to Figure 1 - Figure 6 , the blocking component includes two first baffles 5. The first baffles 5 are arranged on the top of the carrying platform 1. A plug 9 is fixedly connected to the bottom of the first baffle 5. A rubber convex ring 8 is fixedly connected to the outside of the plug 9. Two jacks 11 are provided on the top of the carrying platform 1. A groove 12 is provided inside the jack 11. A trapezoidal groove 7 is provided on one side of the first baffle 5. A trapezoidal block 10 is slidably connected inside the trapezoidal groove 7. A second baffle 6 is fixedly connected to the outside of the trapezoidal block 10. The first baffle 5 is arranged on the top of the carrying platform 1 to prevent goods from slipping off the edge of the platform during transportation. By cooperating with the second baffle 6, double protection is formed, increasing safety. The plug 9 is used to insert into the jack 11, so that the rubber convex ring 8 on the plug 9 is clamped in the groove 12, realizing the fixation between the first baffle 5 and the carrying platform 1. The trapezoidal block 10 is used for the fixation between the second baffle 6 and the first baffle 5. The trapezoidal groove 7 is used for the sliding of the trapezoidal block 10.
[0036] Referring to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , the sliding column 15 is slidably connected inside the arc-shaped groove 13. A plurality of universal wheels 2 are fixedly connected to the bottom of the carrying platform 1. The sliding column 15 is used to control the movement of the handle 4. The arc-shaped groove 13 provides a track for the sliding of the sliding column 15. The carrying platform 1 serves as the basic frame of the trolley and is used to place and transport kitchen supplies. The universal wheels 2 are used to facilitate the pushing of the trolley.
[0037] Refer to Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 and Figure 7 As shown, one end of the spring 18 is fixedly connected to the top of the stop block 19, and the other end of the spring 18 is fixedly connected to the inner wall of the arc plate 3. The spring 18 is used to make the stop block 19 insert into the arc groove 13 and abut against the sliding column 15 without external force. The arc plate 3 is used to carry the handle 4, providing a basis for realizing the folding of the handle 4.
[0038] Refer to Figure 6 - Figure 7 As shown, the stop block 19 is slidably connected inside the arc groove 13, and the stop block 19 abuts against the sliding column 15. The stop block 19 is used to control whether the sliding column 15 can slide inside the arc groove 13, and the arc groove 13 is used for the sliding of the sliding column 15.
[0039] Refer to Figure 7 As shown, a disc 16 is fixedly connected to one end of the pull rod 17. The pull rod 17 is used to pull the stop block 19, and the disc 16 is used to conveniently pull the pull rod 17.
[0040] Refer to Figure 3 、 Figure 4 and Figure 5 As shown, the insertion block 9 is inserted into the insertion hole 11. The insertion block 9 is used to insert into the insertion hole 11 so that the rubber convex ring 8 is clamped in the groove 12, realizing the fixation between the first baffle 5 and the bearing platform 1.
[0041] Refer to Figure 3 and Figure 4 As shown, the rubber convex ring 8 is clamped inside the groove 12. The rubber convex ring 8 is clamped in the groove 12, further realizing the fixation between the first baffle 5 and the bearing platform 1.
[0042] Working principle: When the trolley is needed, pull the handle 4. Then, the rotating shaft 14 will slide between the two arc-shaped plates 3, and the sliding column 15 will slide inside the arc-shaped groove 13. Then, pull the disc 16 upward. Subsequently, the pull rod 17 is driven, starting to compress the spring 18, and the stopper 19 moves upward until the sliding column 15 passes through the stopper 19. Then, put down the disc 16. Under the action of the spring 18, the stopper 19 will be inserted into the arc-shaped groove 13 and abutted against the sliding column 15. When the trolley is not in use, by pulling the disc 16, the stopper 19 will slide upward until the sliding column 15 can slide in the arc-shaped groove 13. Then, slide the handle 4 until the handle 4 fits with the bearing platform 1. Thus, the folding of the trolley is completed, so it is convenient for storage and transportation. When transporting goods, insert the insertion block 9 at the bottom of the first baffle 5 into the jack 11 until the rubber convex ring 8 around the insertion block 9 is clamped in the groove 12 in the jack 11. Thus, the fixation between the first baffle 5 and the bearing platform 1 is achieved. Then, insert the trapezoidal blocks 10 on both sides of the second baffle 6 along the trapezoidal groove 7 on the outside of the first baffle 5. Thus, the fixation of the baffles around the bearing platform 1 is completed, effectively avoiding the goods from falling off the trolley accidentally during transportation and causing damage.
[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
