Description

Technical Field

[0001] The utility model relates to the technical field of flatbed vehicles, in particular to a flatbed vehicle with a cargo fixing function. Background Art

[0002] A flatbed truck is a basic means of transportation. Its design focuses on simplicity and practicality. It is widely used in daily life and various industrial environments, such as warehouses, construction sites, shopping malls and farms. The core function of this handling tool is to provide a stable platform for conveniently moving various items. The center of the flatbed truck is a flat surface, usually made of metal (such as steel), wood or plastic to adapt to different usage requirements, but it plays a key role in simplifying handling tasks. Whether it is a small business or a large enterprise, a flatbed truck is one of the indispensable tools.

[0003] According to the search, the Chinese patent document, announcement number: CN216834082U, discloses that the utility model discloses an electric flatbed truck with cargo limiting function, including: a frame, a handlebar is arranged on one side of the top of the frame, and a seat is connected to the side of the frame close to the handlebar, and a battery box is installed below the side of the frame away from the handlebar; a limiting frame is arranged in parallel on the adjacent two sides of the frame close to the guardrail, and the bottom end of the limiting frame is docked with the frame, and baffles are fixed at both ends of the limiting frame. The electric flatbed truck with cargo limiting function can protect the power-off switch state of the battery box through the shielding cover, and the rubber wheel connected to the inner side of the connecting block can be used for rolling auxiliary guidance with the obstacle surface, and the top of the Y-shaped bracket is squeezed to the inner side of the limiting frame, so that the connecting rod is in the middle horizontal position of the inner side of the limiting frame, and the limiting frame cooperates with the guardrail on one side of the frame to facilitate the electric flatbed truck to limit the cargo boxes stacked on the bottom layer.

[0004] In actual use, the electric flatbed truck with cargo limiting function cannot adjust the height of the flatbed according to actual usage, which causes workers to frequently bend or squat when loading and unloading cargo, and increases the labor intensity of workers. In the long run, it is easy to cause the workers' health to deteriorate and reduce work efficiency. In view of this, we provide a flatbed truck with cargo fixing function. Utility Model Content

When the driving lifting cylinder 2 drives the lifting frame 204 to slide on the surface of the cart 1, since a group of connecting blocks 202 are fixedly connected to the bottom of the platform 3, and the sliding columns 203 on both sides of the bottom of the connecting block 202 penetrate and slide with the inner wall of the lifting groove 205. Connected, when the lifting frame 204 moves, the lifting groove 205 opened on the outer wall drives the platform 3 to move vertically up or down along the limit column 201 through the sliding column 203. After the goods are loaded onto the platform 3 and the door panel 303 is closed, since the fixed plate 305 is restricted inside the platform 3 by the slider 306 and the slide groove 304, the fixed plate 305 can only move along the slide groove 304 on the platform 3. The interior performs linear sliding. When the driving fixed motor 302 drives the hollow threaded roller 307 to rotate through the transmission belt 3010, since the inner wall of the hollow threaded roller 307 is provided with threads, and one end of the threaded shaft 308 is fixed at the center of one side of the fixed plate 305, after the hollow threaded roller 307 rotates, the fixed plate 305 is pushed to the surface of the goods along the slide groove 304 through the internal threads and the threaded shaft 308, and is made to contact with the goods, so that the goods above the platform 3 can be fixed, so that the device can adjust the height of the platform 3 according to the needs of the user, and effectively avoids the workers from frequently bending or squatting when loading and unloading goods due to the fact that the height of the platform 3 is fixed and cannot be adjusted, and at the same time seriously increases the labor intensity of the workers. If things go on like this, it is easy to cause the workers' health to decline and reduce work efficiency.

[0026] When the lifting frame 204 is driven by the lifting cylinder 202, a group of connecting blocks 202 are fixedly connected to the bottom of the platform 3, and the sliding columns 203 on both sides of the bottom of the connecting block 202 penetrate and slide with the inner wall of the lifting groove 205. When the lifting frame 204 moves, the lifting groove 205 opened on the outer wall drives the platform 3 to move vertically up or down along the limiting column 201 through the sliding column 203, so that the device can adjust the height of the platform 3 according to the needs of the user, effectively avoiding the need for workers to frequently bend or squat when loading and unloading goods due to the fixed height of the platform 3 and the inability to adjust it, which seriously increases the labor intensity of the workers. In the long run, it is easy to cause the health of the workers to decline and reduce work efficiency.

[0028] After the cargo is loaded onto the platform 3 and the door panel 303 is closed, since the fixed plate 305 is restricted inside the platform 3 by the slider 306 and the slide groove 304, the fixed plate 305 can only slide linearly along the slide groove 304 inside the platform 3. When the driving fixed motor 302 drives the hollow threaded roller 307 to rotate through the transmission belt 3010, since the inner wall of the hollow threaded roller 307 is provided with threads, and one end of the threaded shaft 308 is fixed to the center of one side of the fixed plate 305, after the hollow threaded roller 307 rotates, the fixed plate 305 is pushed to the surface of the cargo along the slide groove 304 through the internal thread and the threaded shaft 308, and is made to contact with the cargo, so that the cargo above the platform 3 can be fixed, so that when the device is in use, the cargo can be fixed inside the platform 3 through the fixed motor 302 and the fixed plate 305.

[0029] Working principle: In actual use, if the height of the platform 3 needs to be adjusted, since the platform 3 is restricted on the top of the cart 1 by the limit column 201, it can only move up and down vertically along the limit column 201.

When the jacking frame 204 moves, the jacking groove 205 opened on the outer wall drives the platform 3 to move vertically up or down along the limit column 201 through the sliding column 203. After the goods are loaded onto the platform 3 and the door panel 303 is closed, the fixed The fixed plate 305 is restricted inside the platform 3 by the slider 306 and the slide groove 304, and the fixed plate 305 can only slide linearly along the slide groove 304 inside the platform 3. When the driving fixed motor 302 drives the hollow threaded roller 307 to rotate through the transmission belt 3010, since the inner wall of the hollow threaded roller 307 is provided with threads, and one end of the threaded shaft 308 is fixed at the center of one side of the fixed plate 305, after the hollow threaded roller 307 rotates, the fixed plate 305 is pushed along the slide groove 304 to the surface of the goods through the internal thread and the threaded shaft 308, and is made to contact with the goods, so that the goods above the platform 3 can be fixed, so that the device can adjust the height of the platform 3 according to the needs of the user.
