Description

Technical Field

[0001] This utility model relates to the field of flatbed cart technology, and in particular to a flatbed cart with a limiting function. Background Technology

[0002] A flatbed cart is a non-motorized vehicle that carries goods or passengers on its flatbed section. This type of vehicle typically consists of a simple frame, wheels, and axles connecting them. The flatbed section of the frame is used to place goods or provide seating. Flatbed carts are characterized by their simple structure, ease of use, large load capacity, and low cost, and are widely used in workshops, construction sites, and short-distance urban transportation. However, existing flatbed carts lack a restraining mechanism for goods during transport, causing goods to easily slip off during transport, especially on bumpy roads. This can damage the goods and pose certain safety hazards. Therefore, there is an urgent need for a flatbed cart with a restraining function to prevent goods from slipping off. Utility Model Content

[0017] 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.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Reference Figure 1-4 This utility model provides a pallet cart with a limiting function, including a base plate 1, two support rods 2 fixedly connected to the base plate 1, and a push rod 3 fixedly connected between the top ends of the two support rods 2; support plates 4 are installed on both sides of the top surface of the base plate 1, and limiting components are installed on the support plates 4. The two limiting components are symmetrically arranged. A lifting plate 5 is provided on the base plate 1, located on one side of the two support plates 4 and fixedly connected to the two support plates 4. The two support rods 2 pass through the lifting plate 5 and are slidably connected to the lifting plate 5. A lifting component for controlling the up and down movement of the lifting plate 5 is provided between the two support rods 2; casters 6 are installed at the bottom of the base plate 1. By slidingly installing the two support plates 4 on one side of the lifting plate 5, the two limiting components on the two support plates 4 can cooperate to limit the goods, making them less likely to slip during transportation. At the same time, the lifting component can drive the lifting plate 5 to move up and down, thereby adjusting the limiting height of the limiting components, so that the limiting position can be adjusted according to the height of the goods, further increasing the stability of the transport.

[0020] The optimized design includes a limiting component comprising a moving plate 7 located above the base plate 1 and slidably engaged with the lifting plate 5. The moving plate 7 has several sliding rods 8 at the same height. One end of each sliding rod 8 slides through the moving plate 7 and is fixedly connected to a limiting block 9. The other end of each sliding rod 8 is fixedly connected to a limiting plate 10 located between two moving plates 7. Several grooves 11 are correspondingly formed on the moving plate 7 and the bottom wall of the corresponding groove 11. Compression springs 12 are fixedly connected between the moving plate 7 and the bottom wall of the corresponding groove 11. Applying pressure to the limiting plate 10 through the compression springs 12 increases the stability of the structure, ensuring the clamping and limiting effect while preventing significant impact on the moving plate 7 during cargo movement, thus extending its service life.

[0021] In a further optimized design, a threaded rod 13 is rotatably connected to the side of the moving plate 7 closest to the support plate 4. The end of the threaded rod 13 away from the moving plate 7 passes through the support plate 4 and is threadedly connected to it. A crossbar 14 is fixedly connected to the end of the threaded rod 13 away from the moving plate 7. By moving the crossbar 14, the threaded rod 13 can be rotated, thereby adjusting the position of the moving plate 7 so that it can drive the limiting plate 10 to limit the goods.

[0022] In a further optimized design, the threaded rod 13 is positioned correspondingly to the sliding rod 8 located in the middle. A receiving groove 15 is provided at the end of the threaded rod 13 closest to the moving plate 7, and the size of the receiving groove 15 is larger than the size of the limiting block 9. This prevents interference between the threaded rod 13 and the sliding rod 8, ensuring that the limiting plate 10 on the sliding rod 8 can effectively limit the movement of the goods.

[0023] The scheme is further optimized. The lifting assembly includes a top plate 16 located between and fixedly connected to the two support rods 2. A threaded column 17 is rotatably connected between the top plate 16 and the bottom plate 1. The threaded column 17 passes through and is threadedly connected to the lifting plate 5. The top of the threaded column 17 passes through the top plate 16 and is fixedly connected to a turntable 18, which is rotatably connected to the top plate 16. The turntable 18 drives the threaded column 17 to rotate, thereby driving the lifting plate 5 to move up and down. This adjusts the height of the support plate 4 and the moving plate 7 according to the height of the goods, thereby adjusting the height of the limiting assembly and facilitating stable limiting of the goods.

[0024] The design is further optimized by adding several limiting protrusions 19 fixedly connected to the base plate 1. This increases the friction between the cargo and the base plate 1, further enhancing the stability of the cargo.

[0025] The design has been further optimized by adding a spare caster that can be detachably connected to the bottom of the base plate 1. This allows for quick replacement of the caster 6 if it is damaged.

[0026] The working process of this utility model is as follows: When in use, the turntable 18 is rotated to drive the threaded column 17 to rotate, thereby causing the electric lifting plate 5 to move up and down. This adjusts the height of the support plate 4 and the moving plate 7 according to the height of the goods. Then, the crossbar 14 is moved to drive the threaded rod 13 to rotate, thereby causing the moving plate 7 to slide. This allows the position of the moving plate 7 to be adjusted, making it easier to limit goods of different widths. This allows the limiting plates 10 on both sides to contact the goods and clamp and limit them.

[0028] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
