It is a bridge between the production and consumption of fruit and vegetable products, and an indispensable link in the development of commodity economy. In the process of transportation, according to the biological characteristics of fruits and vegetables, the conditions required by fruits and vegetables during transportation should be met as much as possible to ensure the transportation quality.

[0003] In the existing transportation methods of fruits and vegetables, most of the fruits and vegetables are stored in turnover boxes, and then the turnover boxes are stacked in refrigerated trucks for transportation. The turnover boxes often use disposable paper boxes or plastic baskets. On the one hand, these packages cannot meet the strength requirements of fruits and vegetables during the turnover process, especially when stacking, the boxes are prone to squeezing and deformation, which can easily cause damage to the outer skin of fruits and vegetables during transportation. On the other hand, when these boxes are stacked, slippage is likely to occur between the upper and lower boxes, and the stacking structure is not stable enough. Disposable turnover boxes are used for the turnover of fruits and vegetables; when transporting different types of fruits and vegetables, different cushioning structures such as soft pads are required, which will cause serious losses and increased costs to a certain extent.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-8 The present invention provides a technical solution for a fruit and vegetable transport turnover box which is convenient for stacking. The frame box 1 comprises a frame 1.1 and corner posts 1.2 arranged at the four corners of the frame 1.1. The frame 1.1 comprises a rectangular frame 1.1.1, a top beam 1.1.2 arranged parallel to the four sides of the rectangular frame 1.1.1, and a plurality of vertical beams 1.1.3 fixedly connected vertically between the top beam 1.1.2 and the rectangular frame 1.1.1. The four corners of the rectangular frame 1.1.1 are respectively provided with arc-shaped slots 1.1.1.1, and both ends of the top beam 1.1.2 are respectively provided with arc-shaped concave surfaces 1.1.2.1. The corner column 1.2 includes a bottom column 1.2.1 with a top fixedly connected to the arc-shaped slot 1.1.1.1, a tube body 1.2.2 with a bottom fixedly connected to the top of the bottom column 1.2.1 and fixedly connected to the arc-shaped concave surface 1.1.2.1, and a support 1.2.3 movably sleeved on the bottom of the inner cavity of the bottom column 1.2.1 and sleeved with the top of the inner cavity of the tube body 1.2.2. A vertical groove 1.2.2.1 is vertically opened on the side wall of the tube body 1.2.2 toward the center of the frame 1.1; wherein the frame 1.1, the bottom column 1.2.1 and the tube body 1.2.2 are integrally injection molded by polyurethane material. The support 1.2.3 is threadedly sleeved in the inner cavity at the bottom of the bottom column 1.2.1 to facilitate the adjustment of the telescopic length of the support 1.2.3 relative to the bottom column 1.2.1.

[0031] The layered support plate 2 comprises a support frame 2.1 whose four corners are slidably engaged with the vertical groove 1.2.2.1, a short column 2.2 fixed to the four corners of the support frame 2.1 and slidably engaged with the tube body 1.2.2, and a plurality of retractable pillars 2.5 arranged in a rectangular array in the inner cavity of the support frame 2.1 and extending vertically respectively. A sleeve 1 2.3 is threadedly engaged with the bottom of the inner cavity of the short column 2.2, and a sleeve 2.4 is threadedly engaged with the inner thread of the sleeve 1 2.3. A slot 2.2.1 is provided on the top surface of the short column 2.2 and is plugged and matched with the bottom end of the sleeve 2.4. The telescopic support 2.5 comprises a vertical tube 2.5.1 fixed to the inner cavity of the support frame 2.1 in a rectangular array, a partition 2.5.5 fixed to the middle of the inner cavity of the vertical tube 2.5.1, and an elastic member 2.5.4 whose one end is respectively supported on the top and bottom surfaces of the partition 2.5.5, and a sleeve rod 2.5.2 is respectively slidably sleeved in the inner cavity of the vertical tube 2.5.1 and the corresponding end surface of the sleeve rod 2.5.2 is supported on the other end of the elastic member 2.5.4. The sleeve rod 2.5.2 comprises a rod body 2.5.2.1 and an annular protrusion 2.5.2.3 provided on the outer peripheral wall of one end of the rod body 2.5.2.1 and slidably sleeved with the vertical tube 2.5.1, and the outer diameter of the annular protrusion 2.5.2.3 is smaller than the inner diameter of the two ends of the vertical tube 2.5.1. A spherical shell 2.5.2.2 is fixed to the other end of the rod body 2.5.2.1, and a sphere 2.5.3.1 that is rotatably sleeved and matched with the spherical shell 2.5.2.2 is fixed to the side of the flexible circular plate 2.5.3 close to the end of the rod body 2.5.2.1. The flexible circular plate 2.5.3 is made of flexible plastic material, and a spherical concave structure is centrally arranged on the side of the flexible circular plate 2.5.3 away from the sleeve rod 2.5.2, and through holes are arranged on the flexible circular plate 2.5.3. A connecting block 2.6 is fixedly connected between the inner cavity wall of the support frame 2.1 and the outer wall of the adjacent vertical pipe 2.5.1, and between the outer walls of two adjacent vertical pipes 2.5.1.

[0032] In summary, when in use, the telescopic lengths of the sleeve 1 2.3 and the sleeve 2 2.4 are adjusted according to the outer dimensions of the transported fruits and vegetables, so that when the bottom end of the upper sleeve 2 2.4 is inserted into the slot 2.2.1 of the lower layer, the distance between the upper and lower layered support plates 2 is suitable for the placement of the fruits and vegetables. When placing the fruits and vegetables, the flexible circular plate 2.5.3 can be well supported on the outer surface of the fruits and vegetables through the hinged relationship between the sphere 2.5.3.1 and the spherical shell 2.5.2.2, and according to the shape and size of the fruits and vegetables, the flexible circular plate 2.5.3 will correspondingly compress the elastic member 2.5.4 to different degrees through the sleeve rod 2.5.2, so that the appearance of the fruits and vegetables can be evenly supported. Among them, the flexible circular plate 2.5.3 above the vertical tube 2.5.1 supports the fruits and vegetables above it, and the flexible circular plate 2.5.3 below the vertical tube 2.5.1 presses down and positions the fruits and vegetables below it, so as to form an upper and lower package for the fruits and vegetables. In addition, the retractable support 2.5 provides elastic support for the fruits and vegetables, thereby avoiding hard contact with the fruits and vegetables during transportation, thereby reducing damage to the fruits and vegetables caused by vibrations of the transport vehicle such as bumps.

[0033] After placing the fruits and vegetables in each turnover box, when stacking, it is necessary to adjust the extension length of the support column 1.2.3 relative to the bottom column 1.2.1, so that when the support column 1.2.1 corresponding to the upper turnover box is inserted into the top of the inner cavity of the tube body 1.2.2 corresponding to the lower turnover box, the layered support plate 2 at the bottom of the upper turnover box can press down and position the fruits and vegetables on the layered support plate 2 at the top of the lower turnover box.
