[0029] A sliding structure 4 is provided on one side of the base 1, and the sliding structure 4 includes a storage groove 41 opened on one side of the base 1, and an extension plate 42 is slidably connected in the storage groove 41, and a connecting plate 43 is fixedly connected to the side of the extension plate 42 away from the base 1, and a rotating seat 44 is fixedly connected to the front and rear ends of the top of the connecting plate 43, wherein dovetail grooves are opened on the front and rear sides of the inner wall of the storage groove 41, and dovetail sliders are fixedly connected to the front and rear sides of the extension plate 42, so that the extension plate 42 is more stable when sliding in the storage groove 41.

[0030] A mounting structure 5 is provided at the top of the support plate 2, and the mounting structure 5 includes a vertical plate 1 51 fixedly connected to the front and rear ends of the top of the support plate 2. The side opposite to the rotating seat 44 is rotatably connected to the vertical plate 2 52 via a rotating shaft. The sides of the vertical plate 1 51 and the vertical plate 2 52 that are close to each other are rotatably connected via a rotating shaft. Through this structure, the vertical plate 1 51 can always be connected to the vertical plate 2 52.

[0031] A conveying structure 6 is provided on the mounting structure 5, which includes a rotating roller 61 rotatably connected to both sides of the vertical plate 1 51, a conveyor belt 62 is sleeved on the outer side of the rotating roller 61, a motor 2 63 is fixedly installed on the front end of the vertical plate 1 51 away from the vertical plate 2 52, an output end of the motor 2 63 is fixedly connected to the rotating roller 1 61, both sides of the vertical plate 2 52 are rotatably connected with rotating roller 2 64, a conveyor belt 2 65 is sleeved on the outer side of the rotating roller 2 64, and a motor 3 66 is fixedly installed on the front end of the vertical plate 2 52 close to the vertical plate 1 51. The motor 2 63 is used to drive the rotating roller 1 61 to rotate, and then drive the conveyor belt 1 62 to rotate, so as to facilitate the transportation of logistics goods placed above the conveyor belt 1 62. The motor 3 66 is used to drive the rotating roller 2 64 to rotate, and then drive the conveyor belt 2 65 to rotate, so as to facilitate the transportation of logistics goods placed above the conveyor belt 2 65.

[0032] The four corners of the bottom of the base 1 and the front and rear ends of the bottom of the connecting plate 43 are fixedly connected with support legs 7. A movable structure 8 is provided at the bottom of the base 1. The movable structure 8 includes a groove 81 opened at the bottom of the support leg 7. A cylinder 82 is fixedly installed on the top of the inner wall of the groove 81. A push plate is fixedly connected to the bottom of the output end of the cylinder 82. A pulley 83 is fixedly connected to the bottom of the push plate. The pulley 83 facilitates the staff to move the loading and unloading platform to the required position. The cylinder 82 is used to drive the push plate to move upward, and then drive the pulley 83 to retract into the groove 81, so that the support legs 7 can support the loading and unloading platform, thereby improving the stability during the loading and unloading process.

[0033] Several anti-skid ridges 9 are installed at equal intervals on the surface of the conveyor belt 2 65. The setting of the anti-skid ridges 9 increases the friction for the transportation of logistics goods, so that the logistics goods can be transported at a stable conveying speed during the loading and unloading process, and prevents some heavy logistics goods from accelerating down on the inclined conveyor belt 2 65 due to gravity, and then colliding, causing damage to the logistics items.

In the process of the support plate 2 moving up and down, the vertical plate 2 52 rotates along the rotating seat 44. At this time, the extension plate 42 will slide in the storage groove 41, thereby adjusting the angle of the conveyor belt 2 65, and then starts the cylinder 82 to drive the pulley 83 to retract into the groove 81, so that the conveyor belt 1 62 on the top of the support plate 2 is flush with the car body, so as to meet the needs of logistics vehicles or other logistics vehicles of different specifications. The loading and unloading height requirements of other logistics devices are met, and then the motor 2 63 is started to drive the conveyor belt 1 62 to rotate, which is convenient for the transportation of logistics goods placed above the conveyor belt 1 62. At the same time, the motor 3 66 is started to drive the conveyor belt 2 65 to rotate, which is convenient for the transportation of logistics goods placed above the conveyor belt 2 65. The setting of the anti-slip ridges 9 on the conveyor belt 2 65 increases the friction for the transportation of logistics goods, so that the logistics goods can be transported at a stable transmission speed during the loading and unloading process, avoiding some heavier logistics goods from accelerating down on the inclined conveyor belt 2 65 due to gravity, and then colliding, causing damage to the logistics items, thereby improving the practicality of the logistics cargo loading and unloading platform.
