DETAILED DESCRIPTION

[0029] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0030] The structure of the present utility model is described in detail below with reference to the accompanying drawings.

[0031] refer to Figures 1 to 5 As shown, an embodiment of the present invention provides a turnover box for storing and preserving agricultural products, including a box body 1, a box cover 2 is clamped on the top of the box body 1, a support plate 4 and a partition 103 are fixedly connected to the interior of the box body 1, and a support tube 5 is fixedly connected to the four corners inside the box body 1. A gas regulating bag is provided inside the support tube 5, and a telescopic partition frame 3 is slidably installed between the support tube 5 and the support plate 4. The telescopic partition frame 3 slides through the support plate 4, and the four corners of the top of the telescopic partition frame 3 are clamped and fixed to the top of the support tube 5 by elastic positioning members 6, and an ice pack 7 is movably placed inside the corresponding box body 1 below the support plate 4.

[0032] By adopting the above scheme, not only can the interior of the box body 1 be kept in a low-temperature environment by the ice pack 7 to preserve and store the agricultural products, but the gas regulating bag in the support tube 5 can also absorb odors and harmful substances and regulate the gas environment to extend the shelf life of the agricultural products, effectively improving the efficiency of storage and preservation of agricultural products. In addition, the support tube 5 is conducive to the installation and replacement of the gas regulating bag on the one hand, and can effectively fix the telescopic partition frame 3 on the other hand, thereby improving the flexibility of the telescopic partition frame 3, making it quick to disassemble and assemble, and facilitating the separation and placement of the agricultural products inside the box body 1, avoiding collision and wear between the agricultural products, and having good protection, thereby further improving the efficiency of storage and preservation of the turnover box.

[0033] Specifically, a vacuum insulation chamber 102 is set between the partition 103 and the inner bottom of the box body 1, and an insulation rock wool board is fixedly connected to the inside of the vacuum insulation chamber 102. An ice storage chamber 101 is set between the partition 103 and the support plate 4. The ice bag 7 is located in the ice storage chamber 101, and evenly distributed support rods 402 are fixedly connected between the partition 103 and the middle part of the support plate 4.

[0034] The above solution is beneficial to improving the insulation efficiency inside the box 1, extending the service life of the ice pack 7, and then improving the preservation efficiency of agricultural products, facilitating the placement of the ice pack 7, and improving the stability of the connection structure between the partition 103 and the support plate 4.

[0035] Specifically, the support plate 4 is provided with evenly distributed ventilation holes 401 , and the support plate 4 is provided with a sliding groove 403 matching the telescopic partition frame 3 .

[0036] The above solution facilitates low-temperature air to flow through the air holes 401 and fill the interior of the box 1, thereby achieving a low-temperature preservation effect on agricultural products. The sliding groove 403 improves the stability of the connection structure of the telescopic interlayer frame 3.

[0037] Specifically, the telescopic partition frame 3 includes a flexible gauze frame 301 and a flexible gauze frame 302. The flexible gauze frame 301 and the flexible gauze frame 302 are integrally fixedly connected and arranged in a grid-like structure.

[0038] The above solution facilitates the telescopic interlayer frame 3 to be extended and fixed when in use, and to be retracted and folded when not in use, thereby improving the flexibility of the telescopic interlayer frame 3 in use.

[0039] Specifically, there are four elastic positioning members 6, and the elastic positioning members 6 include a positioning slide 601, and the positioning slide 601 is fixedly connected to the top corner of the telescopic partition frame 3. One side of the positioning slide 601 slides along the outer wall of the support tube 5, and the other side of the positioning slide 601 is fixedly connected to a stop block 605, and the stop block 605 abuts against the top of the support plate 4. The bottom of the flexible mesh frame 301 is fixedly connected to the limiting bottom plate 303, and the limiting bottom plate 303 abuts against the bottom of the support plate 4.

[0040] By adopting the above solution, the sliding of the telescopic interlayer frame 3 is restricted by the stopper 605 and the limiting bottom plate 303, thereby preventing the telescopic interlayer frame 3 from being separated from the support plate 4, and the connection is stable and easy to use.

[0041] Specifically, the top of the positioning slide 601 is fixedly connected to a spring 602, the top of the spring 602 is fixedly connected to a top block 603, the side wall of the top block 603 is fixedly connected to a positioning block 604, and a positioning slot 502 is provided on the top of the support tube 5, and the positioning block 604 is tightly inserted into the positioning slot 502.

[0042] When the telescopic partition rack 3 needs to be used to separate agricultural products, the positioning block 604 is pulled upward along the support tube 5 to drive the positioning slide 601 to slide along the support tube 5 until it reaches the positioning slot 502 at the top of the support tube 5, and the positioning block 604 is inserted into the positioning slot 502 through the elastic action of the spring 602, thereby achieving the fixation of the telescopic partition rack 3 when it is extended and used, which is convenient to operate. When not in use, the same reverse operation is performed as above, and the positioning block 604 is taken out of the positioning slot 502. Under the action of gravity, the limiting bottom plate 303 is separated from the bottom of the support plate 4, and the telescopic partition rack 3 slides downward and retracts to the bottom of the support plate 4, and drives the stop block 605 to abut against the top of the support plate 4, thereby achieving effective storage of the telescopic partition rack 3 and flexible use.

[0043] Specifically, the gas regulating pack is an activated carbon regulating pack 501 , and the surface of the supporting tube 5 is provided with evenly distributed through holes.

[0044] Using the above solution, activated carbon is a porous solid carbon material. Due to its highly developed pore structure and huge specific surface area, it has a strong adsorption capacity. It can effectively purify the air in the turnover box, and odors and harmful substances are adsorbed, thereby providing a fresher and healthier storage environment for agricultural products.

[0045] Specifically, a door cover plate 104 is hinged on the side wall of the box body 1 corresponding to the ice pack 7, and sealing rubber pads are fixedly connected to the four side walls of the door cover plate 104.

[0046] The above solution facilitates taking out and putting in the ice pack 7, is easy to use, and ensures the sealing of the interior of the ice storage chamber 101 when the door cover 104 is closed, which is beneficial to improving the heat preservation performance.

[0047] The working principle of this utility model:

[0048] When in use, the agricultural products are placed on the support plate 4 inside the box body 1 and the box lid 2 is closed. The interior of the box body 1 is kept in a low-temperature environment through the ice pack 7 to preserve the agricultural products. The activated carbon adjustment bag 501 in the support tube 5 absorbs odors and harmful substances and adjusts the gas environment to extend the shelf life of the agricultural products. When the telescopic partition rack 3 is needed to separate and place the agricultural products, the positioning block 604 is pulled upward along the support tube 5 to drive the positioning slide 601 to slide along the support tube 5. Under the action of the spring 602, the positioning block 604 is inserted into the positioning slot 502, and the extended telescopic partition rack 3 is fixed on the support tube 5 to achieve separation of the interior of the box body 1. The operation is convenient. When not in use, the reverse operation is performed to make the telescopic partition rack 3 slide downward and retract to the bottom of the support plate 4, so that the telescopic partition rack 3 is effectively stored and flexible to use.
