[0002] A flatbed truck is a simple transportation tool pulled by manpower and is suitable for warehouses, manufacturing factories, etc. The hand-pushed flatbed truck is widely used in production and life because of its low cost, simple maintenance, convenient operation, light self-weight, and can work in places where motor vehicles are inconvenient to use, and it is very convenient for short-distance transportation of light items. Existing flatbed trucks have different body structures. Most general four-wheel hand trucks have a loading platform. Some flatbed truck bodies are made into box shapes, which are suitable for transporting light and easy-to-load and unload items; some flatbed trucks usually need to install guardrails when transporting scattered goods to prevent the center of gravity from being unstable when the goods move, thereby improving the stability of goods transportation.

[0003] The existing flatbed truck guardrails are usually fixedly connected to the vehicle body to form an integral structure. When loading and unloading goods on the flatbed truck, the guardrails are likely to form an obstruction, thereby affecting the efficiency of loading and unloading goods on the flatbed truck.

[0020] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0021] Please refer to Figures 1-4, the embodiments provided by the present utility model: a folding and assembled guardrail for a flatbed vehicle, including a bottom plate 1 for placing goods, a back plate 2 fixedly welded to the top end of the bottom plate 1 for supporting and limiting, universal wheels 7 are rotatably connected to the four corner positions at the bottom end of the bottom plate 1, and the four universal wheels 7 are symmetrically distributed, improving the stability of the support of the bottom plate 1. Two groups of mounting seats one 3 are symmetrically and fixedly welded on the side wall of the back plate 2, the mounting seats one 3 are U-shaped, and a railing assembly 4 is arranged inside each of the two groups of mounting seats one 3. A push rod 5 is fixedly arranged on the side wall of the mounting seat one 3 away from the railing assembly 4, and an anti-slip sleeve is sleeved on the outer surface of the push rod 5 to increase the frictional resistance. The operator can drive the universal wheels 7 to rotate by pushing the push rod 5, so as to conveniently drive the flatbed vehicle to move, and thus conveniently transport goods. Each railing assembly 4 includes a connecting rod one 401 rotatably connected inside the mounting seat one 3, the other ends of the connecting rod one 401 are rotatably connected to a connecting rod two 402, the other ends of the connecting rod two 402 are rotatably connected to a connecting rod three 403, notches one 406 are formed at the ends of the connecting rod one 401 for the connecting rod two 402 to rotate, notches two 407 are formed at the ends of the connecting rod three 403 for the connecting rod two 402 to rotate, and the internal dimensions of the notches one 406 and the notches two 407 are both adapted to the external dimensions of both ends of the connecting rod two 402, improving the stability of the rotation of both ends of the connecting rod two 402. Both ends of the two groups of connecting rod two 402 are rotatably connected to a connecting rod four 404, and the connecting rod one 401, the connecting rod two 402, the connecting rod three 403 and the connecting rod four 404 have the same length. The connecting rod four 404 and the connecting rod two 402 form a rectangle in sequence, improving the overall stability of the folding of the connecting rod two 402. The other ends of the connecting rod three 403 are rotatably connected to a mounting seat two 408, the mounting seat two 408 is U-shaped, and vertical rods 405 are fixedly welded to the ends of the mounting seat two 408 in sequence. The two mounting seats two 408 and the vertical rods 405 are fixedly connected to form an integral structure. The operator can evenly unfold the connecting rod one 401, the connecting rod two 402 and the connecting rod three 403 by pulling the vertical rod 405 to limit the displacement of the goods at the top end of the bottom plate 1. The operator can fold the connecting rod one 401, the connecting rod two 402, the connecting rod three 403 and the connecting rod four 404 in sequence by pushing the vertical rod 405, so as to open both sides of the bottom plate 1, and thus facilitate the loading and unloading of goods.

[0022] The connecting rod one 401, the connecting rod two 402, the connecting rod three 403, the connecting rod four 404 and the vertical rod 405 are all made of stainless steel. Two groups of limiting components 6 are symmetrically arranged near the top end of the back plate 2 close to the vertical rod 405. Each of the two groups of limiting components 6 includes a limiting seat 601 fixedly welded to the top end of the bottom plate 1, a clamping groove 602 is formed on the side wall of the limiting seat 601 for the vertical rod 405 to be clamped, and a magnet block 603 is fixedly arranged on the inner side wall of the clamping groove 602. The magnet block 603 can adsorb the vertical rod 405, thereby improving the stability of the vertical rod 405 clamped inside the clamping groove 602, and thus improving the stability of the unfolding of the connecting rod one 401, the connecting rod two 402 and the connecting rod three 403.

[0023] Working principle: When this folding and assembled guardrail for flatbed trucks is in use, the operator first stacks the goods on the top of the bottom plate 1 in sequence. When the stacking of the goods is completed, the operator pulls the two vertical rods 405 in sequence, so that the first connecting rod 401, the second connecting rod 402, the third connecting rod 403 and the fourth connecting rod 404 are unfolded in sequence, thus blocking both sides of the bottom plate 1, thereby restricting the lateral displacement of the goods. When the operator pushes the push rod 5 to drive the universal wheels 7 to roll, the bottom plate 1 can be driven to move, thereby improving the stability of the goods on the top of the bottom plate 1. When the goods are moved to the designated position, the operator can push the vertical rod 405, so that the first connecting rod 401 and the first connecting rod 401, the second connecting rod 402, the third connecting rod 403 and the fourth connecting rod 404 are folded in sequence, thus realizing the folding and storage of the railing assembly 4, thereby facilitating the opening of both sides of the bottom plate 1, thus releasing the limit, and further facilitating the operator to load and unload the goods.
