[0026] In the prior art, when the hook and the flatbed cart are not in use, the hook has always been exposed. When an object passes by, it is easy to catch the object and it is also easy to damage the hook, which has deficiencies. Therefore, the inventor has studied and provided a flat wheel with a hook, which can automatically store the hook while not affecting the use of the hook, and avoid the risks caused by the hook being exposed for a long time.

[0027] The following will elaborate on some embodiments of the present utility model in conjunction with the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0028] Please refer to Figure 1, the embodiment of the present utility model provides a flat wheel with a hook, a flat plate assembly 100 and a pulley assembly 200. The pulley assembly 200 is installed on the flat plate assembly 100 to support and move the flat plate assembly 100.

[0029] Please refer to Figure 2 , the flat plate assembly 100 includes a flat plate vehicle body 110. By setting fixing bolts at the four corners of the fixing plate 210, the fixing plate 210 is fixedly connected to the flat plate vehicle body 110. It is convenient to install and disassemble the fixing plate 210 through bolts.

[0030] Please refer to Figure 3 , the pulley assembly 200 is fixedly connected to the four corners of the flat plate vehicle body 110. The pulley assembly 200 includes a fixing plate 210, a mounting frame 220, a pulley member 230, a receiving groove 240 and a hook 250. The fixing plate 210 is fixedly connected to the flat plate vehicle body 110. The mounting frame 220 is rotatably connected to the fixing plate 210. The pulley member 230 is rotatably connected between the mounting frames 220. The receiving groove 240 is fixedly connected to the outer side of the mounting frame 220. The hook 250 is rotatably connected in the receiving groove 240. Rotate the hook 250 to make the hook 250 perpendicular to the receiving groove 240. When bundling the items stacked on the flatbed truck, the hook of the rope can be hung on or directly tied to the hook 250 to fix the items. Due to the binding force, the hook 250 will not fall into the receiving groove 240. Then, by rolling the pulley member 230, the items can be moved and transferred. After completion, the items are untied. Losing the binding force, the hook 250 automatically falls back into the receiving groove 240, thus completing the storage of the hook 250 and preventing the hook 250 from being exposed outside, thereby solving the problem in the prior art that when the hook and the flatbed truck are not in use, the hook is always exposed outside, which is prone to various risks. The top of the mounting frame 220 is a rolling bearing, so that the mounting frame 220 is rotatably connected to the fixing plate 210. By setting the rolling bearing, the mounting frame 220 can rotate on the fixing plate 210, thereby driving the pulley member 230 to rotate infinitely, thus realizing the universal function.

[0031] Please refer to Figure 4, the hook 250 includes a hook body 251, a rotating shaft 252 and a torsion spring 253. The hook body 251 is rotatably connected to the receiving groove 240 through the rotating shaft 252. One end of the torsion spring 253 is fixedly connected to the inner wall of the receiving groove 240, and the other end of the torsion spring 253 is fixedly connected to the side of the hook body 251. And the torsion spring 253 is sleeved on the rotating shaft 252, and the torsion spring 253 is symmetrically arranged on both sides of the hook body 251. Rotate the hook body 251 so that the hook body 251 rotates in the receiving groove 240. When the hook body 251 rotates to be perpendicular to the receiving groove 240, hang or directly tie the hook of the rope on the hook 250. At this time, the torsion spring 253 has a certain torsion force, but under the binding force, the hook 250 will not fall into the receiving groove 240. When the transfer of the item is completed, the rope is untied, and the binding force is lost. Under the torsion force of the torsion spring 253, the hook body 251 automatically rotates, so that the hook body 251 rotates into the receiving groove 240, thereby completing the automatic storage of the hook body 251.

[0032] Please refer to Figure 5 , the bottom end of the hook body 251 is designed in a crescent shape. The hook body 251 is provided with a groove and a through hole, which is convenient for tying the rope. The crescent shape design is convenient for pulling the hook body 251 to rotate the hook body 251.

[0033] Please refer to Figure 6 , the pulley member 230 includes a pulley body 231, a pulley shaft 232 and a rolling bearing 233. The pulley body 231 is rotatably connected between the mounting brackets 220 through the pulley shaft 232. The rolling bearings 233 are fixedly connected to both sides of the pulley body 231. The outer shaft of the rolling bearing 233 is fixedly connected to the side wall of the mounting bracket 220, and the inner shaft of the rolling bearing 233 is fixedly connected to the side of the pulley body 231. When pushing the flat car body 110, the pulley body 231 rotates, and at the same time the rolling bearing 233 rotates, so that the pulley body 231 rolls on the mounting bracket 220 while the pulley body 231 does not shake on the pulley shaft 232, improving the stability of the flat car body 110 during movement.

[0034] Please refer to Figure 7 , a rubber ring wheel 234 is fixedly connected to the peripheral side of the pulley body 231. The rubber ring wheel 234 is used to protect the pulley body 231. The surface of the rubber ring wheel 234 is provided with uneven patterns 235. The uneven patterns 235 are used to increase the friction force.

[0035] In summary, the working principle of a flat wheel with a hook according to an embodiment of the present utility model is as follows: When bundling the objects stacked on the flat vehicle body 110, rotate the hook body 251, so that the hook body 251 rotates within the receiving groove 240. When the hook body 251 rotates to be perpendicular to the receiving groove 240, pass a rope through the groove and the through hole on the hook 250 and bundle it on the hook body 251. At this time, the torsion spring 253 has a certain torsional force, but under the bundling force, the hook body 251 will not fall into the receiving groove 240. After the transfer of the item is completed, the rope is untied, and the bundling force is lost. Under the torsional force of the torsion spring 253, the hook body 251 automatically rotates, causing the hook body 251 to rotate into the receiving groove 240, thereby completing the automatic storage of the hook body 251, and solving the problem in the prior art that when the hook and the flatbed cart are not in use, the hook is always exposed, which is likely to cause various risks.
