Description

Technical Field

[0001] This invention relates to the field of fruit and vegetable transportation technology, specifically to fruit and vegetable transport turnover boxes that are easy to stack. Background Technology

[0002] Fruit and vegetable transportation is a crucial method for regulating the market supply of fruit and vegetable products. It serves as a bridge between production and consumption and is an indispensable link in the development of a commodity economy. During transportation, it is essential to consider the biological characteristics of the fruits and vegetables and meet their necessary conditions to ensure transport quality.

[0003] Currently, most fruit and vegetable transportation methods involve storing the produce in reusable containers, which are then stacked in refrigerated trucks for transport. These containers are often disposable paper boxes or plastic crates. However, these packaging methods cannot provide the necessary strength for the fruits and vegetables during handling, especially during stacking, where the containers are easily deformed by compression, potentially damaging the fruit and vegetable skins during transport. Furthermore, these containers are prone to slippage when stacked, resulting in an unstable stacking structure. Using disposable reusable containers for fruit and vegetable transport, and requiring different cushioning structures for different types of fruits and vegetables, can lead to significant losses and increased costs. Summary of the Invention

[0004] The purpose of this invention is to provide a convenient stacking container for transporting fruits and vegetables, which solves the problems of unstable stacking, insufficient support strength, and high cost of existing containers when transporting fruits and vegetables.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a stackable fruit and vegetable transport turnover box, wherein the frame-type box body includes a frame and corner posts located at the four corners of the frame. Each corner post includes a bottom post fixed at the four bottom corners of the frame, a tube fixed at its bottom end to the top of the bottom post and fixed to the four top corners of the frame, and a support column movably fitted into the bottom of the bottom post cavity and fitted into the top of the tube cavity. The side wall of the tube body is provided with a vertical groove along the direction of the center of the frame. The layered support plate includes a support frame that is slidably engaged with the vertical groove at the four corners, short posts fixed at the four corners of the support frame and slidably fitted into the tube body, and a plurality of retractable support columns arranged in a rectangular array in the cavity of the support frame and extending vertically.

[0006] Preferably, the telescopic support column further includes a vertical tube fixed in a rectangular array to the inner cavity of the support frame, a partition fixed in the middle of the inner cavity of the vertical tube, and an elastic element with one end supported on the top and bottom surfaces of the partition. The sleeve rod is slidably sleeved in the inner cavity of the vertical tube, and the corresponding end face of the sleeve rod is supported on the other end of the elastic element.

[0007] Preferably, the sleeve includes a rod body and an annular protrusion disposed on the outer peripheral wall of one end of the rod body and slidably sleeved with the vertical tube, wherein the outer diameter of the annular protrusion is smaller than the inner diameter of both ends of the vertical tube.

[0008] Preferably, a spherical shell is fixed to the other end of the rod, and a sphere that is rotatably fitted and matched with the spherical shell is fixed to the side of the flexible circular plate near the end of the rod.

[0009] Preferably, the flexible circular plate is made of flexible plastic, and the side of the flexible circular plate away from the sleeve rod has a centrally located spherical concave structure, and the flexible circular plate is provided with through holes.

[0010] Preferably, connecting blocks are fixedly connected between the inner wall of the support frame and the outer wall of the adjacent vertical tube, as well as between the outer walls of two adjacent vertical tubes.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figure 1-8 This invention provides a technical solution for a stackable fruit and vegetable transport turnover box. The frame box 1 includes a frame 1.1 and corner posts 1.2 located at the four corners of the frame 1.1. The frame 1.1 includes a rectangular frame 1.1.1, a top beam 1.1.2 parallel to the four sides of the rectangular frame 1.1.1, and several vertical beams 1.1.3 vertically fixed 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 the two ends of the top beam 1.1.2 are respectively provided with arc-shaped concave surfaces 1.1.2.1. The corner post 1.2 includes a bottom post 1.2.1 whose top end is fixedly engaged with an arc-shaped groove 1.1.1.1; a tube body 1.2.2 whose bottom end is fixedly connected to the top end of the bottom post 1.2.1 and correspondingly engaged with the arc-shaped concave surface 1.1.2.1; and a support post 1.2.3 which is movably fitted into the bottom of the inner cavity of the bottom post 1.2.1 and matched with the top end of the inner cavity of the tube body 1.2.2. The side wall of the tube body 1.2.2 has a vertical groove 1.2.2.1 at a position facing the center of the frame 1.1. The frame 1.1, bottom post 1.2.1, and tube body 1.2.2 are integrally injection molded from polyurethane material. The support post 1.2.3 is threaded into the bottom inner cavity of the bottom post 1.2.1 to facilitate adjustment of the extension and retraction length of the support post 1.2.3 relative to the bottom post 1.2.1.

[0031] The layered support plate 2 includes a support frame 2.1 that is slidably engaged with the vertical grooves 1.2.2.1 at its four corners, short columns 2.2 fixed to the four corners of the support frame 2.1 and slidably fitted with the tube body 1.2.2, and several retractable support columns 2.5 arranged in a rectangular array within the cavity of the support frame 2.1 and extending vertically. A sleeve 2.3 is threaded onto the bottom of the inner cavity of the short column 2.2, and a sleeve 2.4 is threaded onto the inner wall of the sleeve 2.3. The top surface of the short column 2.2 has a slot 2.2.1 that matches the bottom end of the sleeve 2.4. The telescopic support 2.5 includes a vertical tube 2.5.1 fixed in a rectangular array within the cavity of the support frame 2.1, a partition 2.5.5 fixed in the middle of the cavity of the vertical tube 2.5.1, and elastic elements 2.5.4 with one end supported on the top and bottom surfaces of the partition 2.5.5. A sleeve 2.5.2 is slidably sleeved within the cavity of the vertical tube 2.5.1, with the corresponding end face of the sleeve 2.5.2 supported on the other end of the elastic element 2.5.4. The sleeve 2.5.2 includes a rod body 2.5.2.1 and an annular protrusion 2.5.2.3 located 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. The outer diameter of the annular protrusion 2.5.2.3 is smaller than the inner diameter of both ends of the vertical tube 2.5.1. A spherical shell 2.5.2.2 is fixed to the other end of the rod 2.5.2.1. A sphere 2.5.3.1, which rotates and fits into the spherical shell 2.5.2.2, is fixed to the side of the flexible circular plate 2.5.3 near the end of the rod 2.5.2.1. The flexible circular plate 2.5.3 is made of flexible plastic. A spherical concave structure is centrally located on the side of the flexible circular plate 2.5.3 away from the rod 2.5.2, and through holes are provided on the flexible circular plate 2.5.3. Connecting blocks 2.6 are fixedly connected between the inner wall of the support frame 2.1 and the outer wall of the adjacent vertical pipe 2.5.1, as well as between the outer walls of two adjacent vertical pipes 2.5.1.

[0032] In summary, during use, the extension lengths of sleeve 1 (2.3) and sleeve 2 (2.4) are adjusted according to the dimensions of the transported fruits and vegetables. This ensures that when the bottom end of the upper sleeve 2 (2.4) is inserted into the lower slot (2.2.1), 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 provide good support 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). Depending on the shape and size of the fruits and vegetables, the flexible circular plate (2.5.3) will compress the elastic element (2.5.4) to varying degrees through the sleeve rod (2.5.2), thus ensuring that the outer surface of the fruits and vegetables is evenly supported. Specifically, the flexible circular plate (2.5.3) above the vertical tube (2.5.1) supports the fruits and vegetables above it, while the flexible circular plate (2.5.3) below the vertical tube (2.5.1) presses down and positions the fruits and vegetables below it, thus forming a top-to-bottom wrap around the fruits and vegetables. In addition, the retractable support column 2.5 provides elastic support for fruits and vegetables, thereby avoiding hard contact with them during transportation and reducing damage to the fruits and vegetables caused by vibrations from the transport vehicle.

[0033] After the fruits and vegetables are placed in each turnover box, when stacking them, 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 of the upper turnover box is inserted into the top of the inner cavity of the tube body 1.2.2 of 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.
