[0023] Embodiment

[0024] Please refer to Figures 1 to 7 , in this embodiment, a flatbed cart with a solenoid valve brake control function is provided, including a base 1. A moving wheel 2 is provided on the lower right side of the base 1, and there are two symmetrically arranged front and rear moving wheels 2; insertion holes 201 are installed on the two moving wheels 2; a universal wheel 20 is installed on the lower left side of the base 1, and there are two symmetrically arranged front and rear universal wheels 20; the flatbed cart can complete the movement of the entire device through the moving wheels 2 and the universal wheels 20; a solenoid valve body 3 is installed on the lower right side of the base 1, and the solenoid valve body 3 is mainly used to control the movement of the flatbed cart and play a braking role; a handrail 5 is installed on the upper left side of the base 1, a start button 4 is installed on the handrail 5, and a power supply box 14 is installed on the right side of the solenoid valve body 3, and the power supply box 14 supplies power to the solenoid valve; the start button 4 is used to control the solenoid valve body 3; a groove 13 is opened on the upper side of the base 1, and the groove 13 is located on the right side of the handrail 5; the groove 13 can be used to place some small items to increase the load capacity; a moving groove 17 is installed on the lower side of the groove 13, and there are two symmetrically arranged front and rear moving grooves 17; extension mechanisms are installed in both of the two moving grooves 17, and the extension mechanisms can not only play a role in blocking and protecting the goods on the flatbed cart, but also expand the load area of the flatbed cart;

[0025] There are two extension mechanisms. Taking the front extension mechanism as an example, the extension mechanism includes a number of first springs 9. A stretching plate 10 is installed on the front side of the first springs 9, and the rear side of the first springs 9 is fixedly installed on a mounting block 91. The mounting block 91 is installed between two groups of first springs 9. When the extension mechanism is in use, first stretch the stretching plate 10 outwards, then place the goods on the carrier plate 16, and finally release the stretching plate 10. Under the elastic action of the first springs 9, the stretching plate 10 squeezes the goods inwards to fix the goods on the flatbed cart. When the stretching plate 10 is stretched outwards, the area of the carrier plate 16 is enlarged, which is convenient for placing more goods and greatly improves the transportation efficiency.

[0026] A carrier plate 16 is installed in the groove 13. A rotating shaft 101 is installed between the rear side of the carrier plate 16 and the base 1. A handle 11 is installed on the top of the carrier plate 16. Anti-slip lines 18 are installed on the carrier plate 16. The anti-slip lines 18 can increase the friction between the articles and the carrier plate 16, making it difficult for the articles to slide off. When the device is in use, the carrier plate 16 is opened through the rotating shaft 101 to expose the groove 13, which is convenient for placing some small articles into the groove 13, and then covering the carrier plate 16 to place large articles on it, which can not only increase the handling capacity of the goods but also prevent small articles from falling during the intermediate transportation.
