[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6A construction handcart includes a cart frame 1. A baffle 2 is provided on the inner wall near the side of the cart frame 1. A rotating rod 3 is fixedly sleeved on the inner wall of the baffle 2, and the outer edge of the rotating rod 3 is rotatably sleeved with the inner wall of the cart frame 1. Gears 4 are fixedly mounted on both sides of the rotating rod 3. An L-shaped plate 5 is slidably connected to the side of the inner wall of the cart frame 1. Connecting blocks 6 are fixedly mounted on both sides of the L-shaped plate 5. A moving groove 11 is opened on the side of the cart frame 1, and the inner wall of the moving groove 11 is slidably connected to the side of the connecting block 6. An outer cylinder 12 is fixedly mounted at the bottom of the inner wall of the L-shaped plate 5. A sliding cylinder 14 is slidably sleeved on the inner wall of the outer cylinder 12. A placement plate 19 is fixedly mounted on the top of the sliding cylinder 14, and the side of the placement plate 19 is slidably connected to the side of the inner wall of the L-shaped plate 5. An auxiliary frame 21 is fixedly mounted on the side. A tension spring 20 is fixedly connected to the side of the inner wall of the auxiliary frame 21. The end of the tension spring 20 away from the inner wall of the auxiliary frame 21 is fixedly connected to the side of the L-shaped plate 5. An inner cylinder 13 is slidably sleeved on the inner wall of the slide cylinder 14. The bottom of the inner cylinder 13 is fixedly mounted to the bottom of the inner wall of the L-shaped plate 5. A base frame 28 is fixedly mounted on the bottom of the trolley outer frame 1. A roller frame 29 is rotatably sleeved on the inner wall of the base frame 28. The rotating rod 3 and the gear 4 work together so that the gear 4 drives the rotating rod 3 to rotate. In turn, the rotating rod 3 drives the baffle 2 to rotate, which helps the L-shaped plate 5 to move away from the inner wall of the trolley outer frame 1, thus facilitating the material unloading. With the addition of the tension spring 20, the L-shaped plate 5 is stably limited to the inner cavity of the trolley outer frame 1 when it is not under force.

[0023] In a preferred embodiment, a sliding plate 7 is fixedly mounted on the side of each of the two connecting blocks 6, and a toothed block 8 is fixedly mounted on the top of the side of each of the two sliding plates 7 away from the connecting block 6. The top teeth of the two toothed blocks 8 mesh with the outer teeth of the two gears 4 respectively. Through the cooperation of the sliding plate 7 and the toothed block 8, the L-shaped plate 5 drives the sliding plate 7 to move through the connecting block 6, and then the sliding plate 7 drives the gear 4 to rotate through the toothed block 8, thereby assisting the gear 4 to drive the baffle 2 to rotate stably.

[0024] In a preferred embodiment, magnet plates 9 are fixedly mounted on the inner walls of both sides of the baffle 2, and magnet plates 10 are fixedly mounted on both sides of the inner wall near the top of the trolley frame 1. The adjacent sides of magnet plates 10 and magnet plates 9 are attracted to each other. Through the cooperation of magnet plates 19 and magnet plates 10, magnet plates 19 are rotated when the baffle 2 rotates. When the outer edge of the toothed plate 4 separates from the toothed block 8, the adjacent sides of magnet plates 19 and magnet plates 20 are attracted to each other, thereby ensuring the stable positioning of the baffle 2 and avoiding interference between the baffle 2 and the L-shaped plate 5.

[0025] In a preferred embodiment, a pull cylinder 22 is fixedly mounted on the side of the L-shaped plate 5, and the outer edge of the pull cylinder 22 is slidably sleeved with the inner wall of the auxiliary frame 21. A circular groove 25 is provided on the side of the pull cylinder 22, and a limiting groove 24 is provided on the side of the inner wall of the circular groove 25. A sliding groove 23 is provided on the side of the inner wall of the limiting groove 24. By using the pull cylinder 22 in conjunction with the auxiliary frame 21, the outer edge of the pull cylinder 22 slides in the inner wall of the auxiliary frame 21, thereby driving the L-shaped plate 5 to move.

[0026] In a preferred embodiment, a limiting plate 27 is slidably connected to the inner wall of the slide groove 23, and the shape and size of the outer edge of the limiting plate 27 are adapted to the shape and size of the inner wall of the limiting groove 24. A pull rod 26 is fixedly mounted on the side of the limiting plate 27. Through the cooperation of the limiting plate 27 and the pull rod 26, the pull rod 26 drives the outer edge of the limiting plate 27 to move from the inner wall of the slide groove 23 to the inner wall of the limiting groove 24, and rotates the limiting plate 27, thereby assisting the outer edge of the limiting plate 27 to be limited in the inner wall of the limiting groove 24.

[0027] In a preferred embodiment, a slide rod 15 is slidably sleeved on the inner wall of the inner cylinder 13, and the top of the slide rod 15 is fixedly assembled with the bottom of the placement plate 19. A magnet ring 16 is fixedly assembled with the bottom of the slide cylinder 14. A coil 17 is fixedly sleeved on the inner wall of the outer cylinder 12 near the bottom, and the inner wall of the coil 17 is slidably sleeved with the outer edge of the magnet ring 16. A spring 18 is fixedly connected to the top of the outer cylinder 12, and the top of the spring 18 is fixedly connected with the bottom of the placement plate 19. Through the cooperation of the slide cylinder 14 and the magnet ring 16, the outer edge of the slide rod 15 is used to limit the sliding within the inner wall of the inner cylinder 13, and the slide rod 15 drives the slide cylinder 14 to slide. Thus, the slide cylinder 14 drives the magnet ring 16 to slide within the inner wall of the coil 17, and the outer edge of the magnet ring 16 slides within the inner wall of the coil 17. In turn, the coil 17 generates electromagnetic damping on the magnet ring 16, thereby assisting the placement plate 19 in shock absorption.

[0028] Working principle: When the device is in use, the pull rod 26 is moved away from the placement plate 19, thereby driving the outer edge of the limiting plate 27 to move within the inner wall of the slide groove 23 until the outer edge of the limiting plate 27 moves into the inner wall of the limiting groove 24. Then, the pull rod 26 is rotated to help the outer edge of the limiting plate 27 to be limited within the inner wall of the limiting groove 24. The pull rod 26 is then moved towards the outer frame 1 of the trolley, thereby driving the L-shaped plate 5 to move. The connecting block 6 moves through the sliding plate 7 and the toothed block 8, thereby driving the baffle 2 to rotate through the gears via the toothed block 8, thus facilitating the easy removal of materials from the trolley. Inside the outer frame 1, materials are easily unloaded. When the material falls to the top of the placement plate 19, the placement plate 19 moves the slide rod 15 and the slide cylinder 14 downward. The outer edge of the slide rod 15 slides in the inner wall of the inner cylinder 13, and the outer edge of the slide cylinder 14 slides in the inner wall of the outer cylinder 12. The inner wall of the slide cylinder 14 slides in the outer edge of the inner cylinder 13, thereby using the slide cylinder 14 to move the outer edge of the magnet ring 16 in the inner wall of the coil 17. The inner wall of the coil 17 generates electromagnetic damping on the magnet ring 16, and the spring 18 assists in pushing the placement plate 19 upward to reset, thereby assisting the placement plate 19 in reducing the vibration of the material.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
