Description

Technical Field

[0001] The present invention relates to the technical field of fruit and vegetable transportation, and particularly relates to a shock-proof fruit and vegetable fresh-keeping transportation box. Background Art

[0002] Vegetables and fruits are rich in various vitamins and minerals necessary for the human body and are one of the essential foods in people's daily lives. In order to meet the needs of consumers in different regions, fresh fruits and vegetables need to be transported from the production place to the consumption place. During transportation, refrigeration is usually used for preservation. Considering the cost, ice cubes are generally used to cool and preserve fruits and vegetables during short-distance transportation. However, fruits and vegetables are easily frostbitten when directly contacting ice cubes for a long time. With the increasing requirements for the quality of life, frostbitten fruits and vegetables are generally difficult to sell, thus causing huge losses to manufacturers and sellers. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides a shock-proof fruit and vegetable fresh-keeping transportation box, which has the advantages of being convenient for fresh-keeping transportation of fruits and vegetables and reducing fruit and vegetable damage.

[0004] To achieve the above object, the technical solution of the present invention is as follows:

[0005] A shock-proof fruit and vegetable fresh-keeping transportation box, comprising:

[0006] An outer box body, at the top opening of which there is a sealed box cover, and on the inner wall of the outer box body there is a refrigeration box fixed, in which there are several cold sources, and several cold air outlets are opened on the refrigeration box;

[0007] An inner box body connected to the outer box body, a refrigeration cavity is formed between the inner box body and the refrigeration box, and several air inlets are opened on the inner box body;

[0008] Several flexible trays arranged vertically in the inner box body, and an accommodation chamber is formed between adjacent flexible trays. The flexible tray includes: a tray frame hinged to the inner box body and a flexible mesh bag fixed in the tray frame; and,

[0009] Several opening and closing components for opening and closing the cold air outlets during transportation. The opening and closing components include: a sealing gate movably assembled in the refrigeration box for closing the cold air outlets, an elastic reset member for making the sealing gate have a tendency to keep closing the cold air outlets, and a pull rope with one end connected to the flexible mesh bag and the other end passing through the inner box body and connected to the sealing gate. The pull rope is pulled by the shaking of the flexible mesh bag to open the cold air outlets by the sealing gate.

[0010] To implement the above technical solution, during transportation, fruits and vegetables are placed in the flexible tray in sequence. When fruits and vegetables are placed on the flexible tray located at the bottom, the flexible tray located at the top can be rotated and opened. The cold air provided in the cold storage box provides cold air for preserving fruits and vegetables. When the cold storage box is in a static state, the sealing gate closes the cold air port to form a cold storage layer outside the inner box body, so that a low-temperature preservation environment is formed inside the inner box body. At the same time, due to the buffering effect of the cold storage cavity, the fruits and vegetables in the inner box body will not directly contact the cold source, thereby reducing the occurrence of frostbite of fruits and vegetables. During transportation, when the transport vehicle accelerates or decelerates, the fruits and vegetables are in inertia. Under the action, the flexible net bag will shake, thereby driving the pull rope to move and pull up or loosen the sealing gate. When the sealing gate is pulled up by the pull rope, cold air is discharged into the accommodating chamber from the cold air port, and then enters the inner box from the air inlet, so that the temperature inside the inner box is cooled again to ensure the freshness during transportation. When the pull rope is loosened, the sealing gate will close the cold air port again under the action of the elastic reset member, so that the cold air will continue to enter the inner box and keep the temperature inside the inner box within a suitable range. At the same time, since the fruits and vegetables are supported by the flexible net bag, the bumps during transportation are reduced, reducing damage to the fruits and vegetables.

[0011] As a preferred solution of the present invention, the sealing gate is slidably assembled on the refrigerated box along the vertical direction, a plurality of the cold air outlets are arranged corresponding to each of the sealing gates, a plurality of through openings corresponding to the cold air outlets are opened on the sealing gate, and when the sealing gate closes the cold air outlet, the cold air outlet and the through openings are staggered up and down.

[0012] To implement the above technical solution, by providing a plurality of cold air openings and passages, a better refrigeration and preservation effect can be achieved during one opening and closing process.

[0013] As a preferred solution of the present invention, a U-shaped slide rail is provided on the outer wall of the cold storage box, the sealing gate is slidably connected to the U-shaped slide rail, and a sealing ring is provided outside each of the through openings.

[0014] The above technical solution is implemented to facilitate the sliding of the sealing gate to open and close the cold air port, and the sealing performance of the sealing gate to the cold air port can be ensured by the sealing ring.

[0015] As a preferred solution of the present invention, a first hook ring is provided on the sealing gate, a second hook ring is provided on the U-shaped slide rail, and the elastic reset member is a tension spring with one end connected to the first hook ring and the other end connected to the second hook ring.

[0016] Implementing the above technical solution makes it easier to install the elastic reset member.

[0017] As a preferred solution of the present invention, a wire passing hole is provided on the inner box body, an L-shaped wire tube is embedded and fixed in the wire passing hole, and the pull rope is passed through the L-shaped wire tube.

[0018] Implement the above technical solution, which facilitates pulling the sealing gate with a pull rope and reduces the friction between the pull rope and the inner box body.

[0019] As a preferred solution of the present invention, a weight is fixed on the pull rope below the flexible tray.

[0020] Implement the above technical solution. By setting the weight, the pulling force generated by the pull rope during transportation is further increased, making it more convenient to open and close the sealing gate.

[0021] As a preferred solution of the present invention, an installation opening is provided at the bottom of the outer box body, and an installation component for installing the cold source is inserted into the installation opening. The installation component includes: an installation frame inserted and sealed with the installation opening, and an installation plate fixed to the installation frame. The cold source is detachably connected to the installation plate.

[0022] As a preferred solution of the present invention, the cold source is an ice bag and / or a cold storage agent package, and the cold source is connected to the installation plate by a sticky fastener or a magic tape.

[0023] Implement the above technical solution, which facilitates the installation, disassembly and reuse of the cold source.

[0024] As a preferred solution of the present invention, a cross brace for lapping the flexible tray is provided on the inner wall of the inner box body.

[0025] Implement the above technical solution. By supporting the flexible tray with the cross brace, the flexible tray can stably hold fruits and vegetables.

[0026] In summary, the present invention has the following beneficial effects:

[0027] In an embodiment of the present invention, a shock-proof fresh-keeping transportation box for fruits and vegetables is provided. During transportation, the fruits and vegetables are sequentially placed in a flexible tray. When the fruits and vegetables are placed on the flexible tray located below, the flexible tray located above can be rotated and opened. Cold air for preserving the fruits and vegetables is provided by a cold source arranged in the refrigeration box. When the refrigeration box is in a static state, the sealing gate closes the cold air outlet, forming a refrigeration layer outside the inner box body, so that a low-temperature fresh-keeping environment is formed inside the inner box body. At the same time, due to the buffering effect of the accommodation chamber, the fruits and vegetables inside the inner box body do not directly contact the cold source, reducing the occurrence of the phenomenon that the fruits and vegetables are frostbitten; during transportation, when the transport vehicle accelerates or decelerates, the fruits and vegetables will drive the flexible mesh bag to shake under the action of inertia, thereby driving the pull rope to move to pull up or loosen the sealing gate. When the sealing gate is pulled up by the pull rope, the cold air is discharged from the cold air outlet into the accommodation chamber, and then enters the inner box body through the air inlet hole, so that the temperature inside the inner box body is reduced again, ensuring the fresh-keeping ability during transportation. When the pull rope is loosened, the sealing gate closes the cold air outlet again under the action of the elastic reset member, so that the cold air will not continuously enter the inner box body, keeping the temperature inside the inner box body within a suitable range; at the same time, since the fruits and vegetables are supported by the flexible mesh bag, the bumps during transportation are reduced, reducing the damage to the fruits and vegetables.

When the sealing gate 41 closes the cold air outlet 14, it is plugged and abutted against the bottom of the U-shaped slide rail 5, thereby further improving the sealing performance between the sealing gate 41 and the cold air outlet 14, and the sealing performance of the sealing gate 41 for the cold air outlet 14 can be ensured through the sealing ring 412.

[0040] Further, a first hook ring 413 is provided on the sealing gate 41, and a second hook ring 51 is provided on the U-shaped slide rail 5. The elastic reset member 42 is a tension spring with one end connected to the first hook ring 413 and the other end connected to the second hook ring 51, thereby facilitating the installation of the elastic reset member 42. A wire passing hole is formed in the inner box body 2, and an L-shaped wire conduit 24 is fixedly embedded in the wire passing hole. The pull rope 43 passes through the L-shaped wire conduit 24. The inner wall of the L-shaped wire conduit 24 is smooth, thus facilitating the pull rope 43 to pull the sealing gate 41 and reducing the friction between the pull rope 43 and the inner box body 2.

[0041] Further, a weight 44 is fixed on the pull rope 43 below the flexible tray 3. The weight 44 can be in the shape of a cube, a sphere, etc. By providing the weight 44, the pulling force generated by the pull rope 43 during transportation is further increased, making it more convenient to open and close the sealing gate 41.

[0042] Meanwhile, an installation opening is provided at the bottom of the outer box body 1, and an installation component 6 for installing the cold source 13 is inserted into the installation opening. The installation component 6 includes: an installation frame 61 inserted and sealed with the installation opening, and an installation plate 62 fixed to the installation frame 61. The cold source 13 is detachably connected to the installation plate 62.

When the fruits and vegetables are placed on the flexible tray 3 located below, the flexible tray 3 located above can be rotated and opened. The cold source 13 provided in the refrigerating box 12 provides cold air for preserving the freshness of the fruits and vegetables. When the refrigerating box is in a static state, the sealing gate 41 closes the cold air port 14, and a refrigerating layer is formed outside the inner box body 2, so that a low-temperature fresh-keeping environment is formed inside the inner box body 2. At the same time, due to the buffering effect of the refrigerating cavity 21, the fruits and vegetables inside the inner box body 2 do not directly contact the cold source 13, reducing the occurrence of the phenomenon that the fruits and vegetables are frozen; during transportation, when the transport vehicle accelerates or decelerates, the fruits and vegetables will drive the flexible mesh bag 32 to shake under the action of inertia, thereby driving the pull rope 43 to move to pull up or loosen the sealing gate 41. When the sealing gate 41 is pulled up by the pull rope 43, the cold air is discharged from the cold air port 14 into the accommodating chamber 22, and then enters the inner box body 2 through the air inlet hole 23. Thus, the temperature inside the inner box body 2 is reduced again to ensure the freshness-keeping ability during transportation. When the pull rope 43 is loosened, the sealing gate 41 closes the cold air port 14 again under the action of the elastic reset member 42, so that the cold air does not continuously enter the inner box body 2, and the temperature inside the inner box body 2 is maintained within a suitable range; at the same time, since the fruits and vegetables are supported by the flexible mesh bag 32, the collision during transportation is reduced, and the damage to the fruits and vegetables is reduced.
