[0041] The box 12 includes movable front plate 121, the movable front plate 121 is vertically slidably installed on the front side of the frame 11, and the movable front plate 121 is used to open or close the front opening, when the movable front plate 121 is located in the upper containing cavity, the movable front plate 121 closes the front opening, and when the movable front plate 121 is located in the lower containing cavity, the movable front plate 121 opens the front opening.

[0042] The front side of the frame 11 is provided with limiting component 5, and the limiting component 5 is used to limit the movable front plate 121 to the front side of the upper containing cavity.

[0043] Wherein, car body 1 is provided with the upper opening and the front opening that are interconnected, and the operator can choose to vertically place carton into car body 1 from the upper opening, or horizontally enter the paper box into car body 1 through the front opening, and the flexible double-opening intercommunication mode can be used to take the paper box inside the cart from the front opening by the operator, so that the operator needs to bend down to take the paper box in the deep part of the cart.

[0044] By adjusting the first turnover plate assembly 3, the interior space of the vehicle body 1 forms two independent and interconnected areas of the upper containing cavity and the lower containing cavity. The upper containing cavity is connected with the front opening through the upper opening. Such design not only facilitates the rapid access of articles, but also optimizes the space layout, so that a plurality of cartons can be stored in the upper and lower two areas according to the size.

[0045] By adjusting the position and state of the second turnover plate assembly 4, the lower containing cavity can be flexibly divided into left and right sub-areas, realizing more fine management of the space in the vehicle body 1.

[0046] Among them, the first turnover plate assembly 3 and the second turnover plate assembly 4 interact and cooperate to divide the interior of the vehicle body 1 into the upper containing cavity, the left part of the lower containing cavity, and the right part of the lower containing cavity, realizing the function of partitioning the interior space of the vehicle body 1.

The limiting assembly 5 is located on the side wall of the U-shaped groove 1221, and the movable end of the limiting assembly 5 movably extends into the movable area 1223 and abuts against the movable front plate 121 located at the top of the fixed area 1222.

[0049] The fixed front plate 122 is fixedly installed at the bottom of the fixed area 1222, which can seal the front side of the lower containing cavity. This not only enhances the ability of the front side of the vehicle body 1 to resist external impact, effectively reduces the probability of damage to the carton due to external impact and friction, but also prevents the carton from falling off and separating from the vehicle body 1 during transportation.

[0050] When the operator needs to close the front opening, the movable front plate 121 is pushed upwards so that it is located at the top of the movable area 1223, and then it is pushed inwards so that it is located at the top of the fixed area 1222. At this time, the bottom of the movable front plate 121 abuts against the top of the fixed front plate 122, and the rear side of the movable front plate 121 abuts against the groove wall of the U-shaped groove 1221, thereby quickly and conveniently closing the front opening of the upper containing cavity.

[0051] In order to prevent the movable front plate 121 from being displaced accidentally and the front opening from being opened inadvertently due to the shaking of the vehicle body 1, a limiting assembly 5 is arranged on the side wall of the U-shaped groove 1221. The movable end of the limiting assembly 5 abuts against the movable front plate 121, so that it is stably fixed at the specified position, thereby preventing the generation of safety hazards such as the sliding and scattering of the cartons.

[0052] When the operator needs to take out the cartons in the cart, the limiting assembly 5 is rotated so that the movable end of the limiting assembly 5 extends out of the movable area 1223, and the movable front plate 121 is pushed so that it is located at the bottom of the movable area 1223.
