[0017] The present invention discloses a floor structure and a container in an embodiment. The container includes a box body 4, a refrigerator 5 and the floor structure. Figure 2 The floor structure includes a T-shaped floor 1, a ventilation slot 2 and a support plate 3. The ventilation slot 2 is a channel formed by the cross section of the T-shaped floor 1, and the support plate 3 is laid on the T-shaped floor 1.

[0018] See also Figure 3 and Figure 4 The support plate 3 has a double-layer structure, including a metal support base plate 32 and an insulating rubber pad 33. The support plate 3 is provided with a plug welding hole 34, through which the metal support base plate 32 is plug-welded to the T-shaped floor 1 made of the same material. The insulating rubber pad 33 wraps around the upper surface of the metal support base plate 32. This helps reduce the amount of cold transferred through the T-shaped floor 1 and the metal support base plate 32. The upper surface of the insulating rubber pad 33 has a concave-convex structure, which increases friction between the operator and the support plate 3 and prevents slipping.

[0019] The support plate 3 is provided with multiple rows of air holes 31, each row of air holes 31 being located above the ventilation slots 2. The aperture of each row of air holes 31 increases from the front end to the rear end of the support plate 3. The air holes 31 in the embodiment shown in the drawings are square, but the shape of the air holes 31 is not limited to square; other shapes such as circular and triangular are also possible.

[0020] To facilitate production and installation, the support plate 3 can be composed of small support plates with the same double-layer structure. It is only necessary to ensure that the aperture of each column of pores 31 of the entire large support plate 3 increases from the front end to the rear end of the support plate 3.

[0021] The cooler 5 is welded and fixed to the front end of the box body 4. The air outlet of the cooler 5 faces the ventilation slots 2 of the floor structure, and the front end of the support plate 3 is located at the front end of the box body 4. When the cooler 5 blows air, the air output at the front end of the box is suppressed by the smaller aperture 31. More cooling air will be directed to the rear end of the box through the ventilation slots 2. The air output at the rear end of the box increases as the aperture 31 increases. The rear end of the box can obtain a greater cooling capacity than the existing technology, thereby balancing the temperature inside the box. At this time, the cooling capacity of the box can be seen in the following figure. Figure 5 .

[0022] In summary, the utility model suppresses the air output at the front end of the box by adding air holes 31 of different apertures on the floor structure, and adjusts the air output to increase from the front end to the rear end, so that the rear end can obtain greater cooling capacity compared with the existing technology, thereby reducing the temperature difference between the front and rear ends of the box, ensuring uniform temperature in the box, and allowing the transported goods to obtain balanced cooling capacity at different positions.

[0023] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
