[0002] Cold chain means that certain items are kept in a specific low-temperature environment required for the production, storage, transportation and sales of the products to reduce losses and avoid contamination and deterioration of the items. Cold chain is often used in food, biology, medicine and other fields. Special boxes are needed for storage during cold chain transportation to prevent the external temperature from affecting the items. When broilers are transported in the cold chain, they are usually placed inside an insulated box for transportation.

[0003] Chinese invention patent publication number: (CN113443276B) A refrigerated box for cold chain transportation, in which the volume of the T-block is smaller than the internal volume of the T-hole, so that there is a fitting margin between the T-block and the T-hole, so that the vibration will not be completely transmitted to the refrigeration device due to the rigid connection, thereby reducing the vibration intensity of the refrigeration device and avoiding the loss of materials or food stored in the refrigeration device under the influence of vibration. At the same time, a margin groove is provided on the bottom of the refrigeration compartment near one side and the material of the limiting wheel is soft and wear-resistant rubber, so that there is a certain margin for the installation between the refrigeration devices, so that the heat conduction device will not be in a completely closed and static state with the top of the refrigeration compartment under the action of vibration, avoiding the problem that the heat conduction device and the refrigeration compartment are closed for too long and condensed under the action of low temperature and water vapor, resulting in the heat conduction device being unable to open normally, thereby improving the stability of the device during use.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1 In this embodiment, an insulated box for cold chain transportation of broilers includes an insulated box body 1, a cover plate 2, two placement plates 3 and four second slide bars 7. The cover plate 2 is hinged to the right side of the insulated box body 1 through a hinge shaft. The four second slide bars 7 are fixed to the inside of the insulated box body 1 in a group of two and are symmetrically fixed up and down. When one of the placement plates 3 moves, it also slides inside one group of second slide bars 7. The two placement plates 3 are respectively slidably connected to the inside of the two groups of second slide bars 7. A driving mechanism 4 for moving the placement plates 3 is provided inside the insulated box body 1. A moving mechanism 5 for moving the insulated box body 1 is provided on the lower surface of the insulated box body 1. A stacking mechanism 6 is provided on the upper surface of the insulated box body 1.

[0028] See also Figure 2-3In order to facilitate the driving of the placement plate 3, the driving mechanism 4 in this embodiment includes a driving component and a conversion component. The driving component includes a threaded rod 401 rotatably connected to the left side wall of the inner cavity of the insulation box body 1 through a bearing. The outer side of the threaded rod 401 is threadedly connected to a threaded sleeve 402. When the threaded rod 401 rotates through the threaded connection, the threaded sleeve 402 threadedly connected thereto moves to the right. The output shaft is fixed to the left side of the insulation box body 1 and extends to the inside of the insulation box body 1. The electric control switch of the motor 403 is turned on. The output shaft of the motor 403 rotates to drive the threaded rod 401 connected to it to rotate. The threaded rod 401 is fixed to the outside of the output shaft of the motor 403. The limit plates 404 are fixed on the front and rear sides of the outer surface of the threaded sleeve 402. The two limit plates 404 limit the threaded sleeve 402 to ensure that when the threaded rod 401 rotates, the threaded sleeve 402 supports the left and right lateral movement. The driving assembly also includes a first slide bar 405 fixed to the front and rear side walls of the inner cavity of the insulation box body 1, and the two limit plates 404 are slidably connected to the inside of the two first slide bars 405 respectively.

[0029] The shape of the insulation box body 1 is a rectangular parallelepiped with a hollow interior and a missing right side. Two lifting ears are fixed on the front and back sides of the insulation box 1 by bolts. The two placement plates 3 are symmetrically distributed on the upper and lower sides of the horizontal center axis of the threaded rod 401. The left side wall of the inner cavity of the insulation box body 1 is provided with a rotating through hole for the output shaft of the power supply motor 403 to rotate and to fit with the clearance. A limit block with an outer diameter larger than the inner diameter of the threaded sleeve 402 is fixed on the right end face of the threaded rod 401.

[0030] The conversion assembly includes a rotating ring 406 that is rotatably connected to the outside of the threaded sleeve 402, and a rotating plate 407 is fixed to the outside of the rotating ring 406. A connecting plate 408 is fixed to the upper end face of the rotating plate 407. Rotating the rotating plate 407 drives the connecting plate 408 connected to it to rotate. Positioning blocks 409 are fixed on the opposite sides of the two placement plates 3. When the connecting plate 408 is inserted into the upper positioning block 409, the threaded sleeve 402 moves and drives the positioning block 409 connected to it to move. The upper positioning block 409 is movably sleeved on the outside of the connecting plate 408. When the positioning block 409 moves, it drives the upper placement plate 3 to move, thereby removing the broiler on the upper surface of the upper placement plate 3 from the inside of the incubator body 1.

[0031] It can be understood that when the lower placement plate 3 needs to be moved, the connecting plate 408 is inserted into the interior of the lower positioning block 409 by rotating the rotating plate 407 in the opposite direction, and the lower placement plate 3 is driven to move by the lower positioning block 409. At this time, the broiler on the upper surface of the lower placement plate 3 can be moved out from the interior of the incubator body 1.

[0032] The cross-section of the right side of the connecting plate 408 is arc-shaped. The interiors of the two positioning blocks 409 are provided with arc-shaped grooves for inserting the connecting plate 408. The two positioning blocks 409 are located on the same plumb line, and the rotating plate 407 is fixed at the center of the lower end face of the connecting plate 408.

[0033] The driving mechanism 4 in this embodiment drives the threaded rod 401 connected thereto to rotate through the driving action of the motor 403. Through the action of the threaded connection, the threaded rod 401 drives the placement plate 3 connected thereto to move rightward when rotating.

[0034] See also Figure 4 In order to facilitate movement, the moving mechanism 5 in this embodiment includes a support box 501 fixed to the lower surface of the insulation box body 1, and the interior of the support box 501 is slidably connected to the bottom plate 502. A rotating rod 503 is rotatably connected between the front and rear side walls of the inner cavity of the support box 501 through a bearing. Two gears 504 are fixed to the outside of the rotating rod 503. A handwheel 505 with one end passing through and extending into the interior of the support box 501 is fixed on the front side of the support box 501. When two insulation box bodies 1 need to be stacked, the rotating rod 503 connected thereto is driven to rotate by rotating the handwheel 505. The rotating rod 503 is fixed to the outside of the handwheel 505, and the outer sides of the two gears 504 are meshed with a tooth plate 500 whose lower end surface is fixed to the upper surface of the bottom plate 502. 6. The rotating rod 503 drives the two outer gears 504 to rotate. Through the meshing effect, the gear 504 drives the meshing tooth plate 506 to move upward when rotating. The upper end surfaces of the two tooth plates 506 pass through the support box 501 and extend to the interior of the insulation box body 1. The moving mechanism 5 also includes two protective sleeves 507 fixed on the bottom wall of the inner cavity of the insulation box body 1. The two tooth plates 506 extend into the protective sleeves 507 inside the insulation box body 1. The two tooth plates 506 are protected by the two protective sleeves 507 respectively, and the two through holes are sealed by the two protective sleeves 507. The two protective sleeves 507 are respectively mounted on the outside of the two tooth plates 506, and universal wheels 508 are fixed to the four corners of the lower surface of the bottom plate 502.

[0035] It is understandable that when the tooth plate 506 moves upward, it simultaneously drives the bottom plate 502 and the four universal wheels 508 to move upward, and the four universal wheels 508 are all retracted into the interior of the support box 501.

[0036] The support box 501 is in the shape of a rectangular parallelepiped with a hollow interior and a missing lower surface. The length and width of the bottom plate 502 are respectively adapted to the length and width of the inner cavity of the support box 501 .

[0037] The moving mechanism 5 in this embodiment is provided with four moving wheels on the lower surface of the bottom plate 502, thereby facilitating the movement of the entire thermal insulation box body.

[0038] See also Figure 5 In order to facilitate the stacking of two insulated box bodies 1, the stacking mechanism 6 in this embodiment includes a card plate 601 fixed to the upper end surface of the insulated box body 1, and the stacking mechanism 6 also includes four positioning pins 602 fixed to the lower end surface of the support box 501. The upper end surface of the insulated box body 1 is provided with four positioning holes 603 for inserting the four positioning pins 602 respectively. By lifting one of the insulated box bodies 1 and moving it above the other insulated box body 1, the four positioning pins 602 below the upper insulated box body 1 are inserted into the four positioning holes 603 on the upper end surface of the insulated box body 1 below.

[0039] Four positioning pins 602 are respectively fixed at the four corners of the lower end surface of the support box 501 , and the length and width of the clamping plate 601 are respectively equal to the length and width of the bottom plate 502 .

[0040] The stacking mechanism 6 in this embodiment is achieved by inserting the positioning pins 602 below the hoisted insulation box body 1 into the four positioning holes 603 inside the other insulation box body 1, and the lower clamping plate 601 extends to the inside of the upper support box 501, at which time the stacking of the upper and lower insulation box bodies 1 is completed.

[0041] The working principle of the above embodiment is:

[0042] (1) During use, by turning on the electric control switch of the motor 403, the output shaft of the motor 403 rotates and drives the threaded rod 401 connected thereto to rotate. When the threaded rod 401 rotates through the action of the threaded connection, the threaded sleeve 402 threadedly connected thereto moves to the right, that is, the rotating plate 407 rotates to drive the connecting plate 408 connected thereto to rotate. After the connecting plate 408 is inserted into the interior of the upper positioning block 409, the threaded sleeve 402 moves and drives the positioning block 409 connected thereto to move. When the positioning block 409 moves, it drives the upper placement plate 3 to move, thereby moving the broiler on the upper surface of the upper placement plate 3 out of the interior of the incubator body 1. When it is necessary to move the lower placement plate 3, the rotating plate 407 is rotated in the opposite direction so that the connecting plate 408 is inserted into the interior of the lower positioning block 409, and the lower placement plate 3 is driven to move through the lower positioning block 409. At this time, the broiler on the upper surface of the lower placement plate 3 can be moved out of the interior of the incubator body 1.

[0043] (2) By setting four universal wheels 508 on the lower surface of the bottom plate 502, the heat preservation box body 1 is moved by pushing it. When two heat preservation box bodies 1 need to be stacked, the rotating rod 503 connected to it is driven to rotate by rotating the hand wheel 505, and the rotating rod 503 drives the two outer gears 504 to rotate. Through the meshing effect, the gear 504 drives the tooth plate 506 meshed with it to move upward when rotating. The two tooth plates 506 extend into the protective cover 507 inside the heat preservation box body 1, and at the same time drive the bottom plate 505 to rotate. 02 and the four universal wheels 508 move upward, and the four universal wheels 508 are retracted into the interior of the support box 501. By lifting one of the insulated box bodies 1 and moving it above the other insulated box body 1, the four positioning pins 602 below the upper insulated box body 1 are inserted into the four positioning holes 603 on the upper end surface of the lower insulated box body 1. At the same time, the clamping plate 601 extends to the interior of the upper support box 501. At this time, the two insulated box bodies 1 are stacked up and down, which effectively facilitates transportation.
