[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Reference Figure 1-8The multi-layered refrigerated and frozen drawer cabinet shown includes a freezer body 1, a cabinet door 2, and drawers 10. The cabinet door 2 is hinged to the freezer body 1, and the drawers 10 are slidably connected in the drawer slots of the freezer body 1. A drive cavity 100 is provided in the freezer body 1, and a release limiting mechanism is provided in the drive cavity 100 to open and close the cabinet door 2. In order to prevent the drawers 10 from shaking during transportation, a U-shaped limiting member 11 is provided on the back of the drawers 10. The limiting member 11 is connected to the release limiting mechanism to limit the drawers 10. An anti-dropping mechanism is provided on the drawers 10. When the drawers 10 are pulled out of the drawer slots, they are slidably connected to the drawer slots through the anti-dropping mechanism to prevent them from being directly separated from the freezer body 1.

[0027] As one embodiment of this invention, the release mechanism is as follows: the drive cavity 100 is L-shaped, and a rotating groove 101 is provided on the inner top surface of the drive cavity 100. Two sets of rotating shafts 3 are rotatably connected in the drive cavity 100, and one set of rotating shafts 3 is connected to the cabinet door 2. Therefore, when the cabinet door 2 is flipped, it drives one set of rotating shafts 3 to flip. A rotating rod 4 is provided on one side of the rotating shaft 3. The rotating rod 4 is rotatably connected in the rotating groove 101. The limiting member 11 is slidably connected in the rotating groove 101. A limiting block 9 is provided on the outer wall of the rotating rod 4. The limiting block 9 is wedge-shaped. When the limiting block 9 is flipped, it slides in the groove of the limiting member 11. The rotating rod 4 and the rotating shaft 3 are connected by a transmission assembly.

[0028] As one embodiment of this invention, the transmission assembly includes two sets (vertically arranged) of rotating shaft 3. A first synchronous pulley 5 is provided on the rotating shaft 3, and the two sets of first synchronous pulleys 5 are connected by a first synchronous belt 6. A second synchronous pulley 7 is provided on the rotating shaft 3 and the rotating rod 4 (the rotating rod 4 is arranged parallel to the second set of rotating shaft 3), and the two sets of second synchronous pulleys 7 are connected by a second synchronous belt 8.

[0029] As one embodiment of this example, the inner top surface of the drawer slot is provided with a driving groove 102 and a limiting groove 104. The limiting groove 104 and the driving groove 102 are arranged side by side. A sliding groove 103 is provided on the inner wall of the drawer slot. The sliding groove 103 and the limiting groove 104 are connected.

[0030] The front of the drawer 10 is provided with two sets of symmetrical grooves 1000, and the outer wall of the drawer 10 is provided with a placement groove 1001. The rear of the placement groove 1001 is provided with a receiving groove 1002, which is compatible with the sliding groove 103.

[0031] As one embodiment of this invention, the anti-fall-off mechanism consists of a rack 12 fixed in the drive groove 102 by bolts (when the drawer 10 needs to be completely removed from the drawer slot, the rack 12 in the drive groove 102 can be removed first to release the limit). A set of driven rods 14 are rotatably connected in the placement groove 1001. One end of the driven rod 14 is disc-shaped, and teeth are provided on the outer wall of the disc-shaped driven rod 14. The teeth on the driven rod 14 mesh with the rack 12 through the upper adapter gear 13 (rotatably connected to the placement groove 1001). A connecting rod 15 is provided at the free end of the driven rod 14, and a slide head 16 is provided on the top surface of the connecting rod 15. The slide head 16 is slidably connected to the limit groove 104. Through the cooperation of the above structure, when the drawer 10 is pulled outward, the drawer 10 is prevented from falling directly out of the drawer slot.

[0032] The working principle of this utility model is as follows: When the cabinet door 2 on the main body 1 of the freezer is opened, the cabinet door 2 rotates during the flipping process, which drives a set of coaxial rotating shafts 3 to rotate in the drive cavity 100. The rotating shafts 3 drive the first synchronous wheel 5 to rotate. Then, the rotating first synchronous wheel 5 drives another set of rotating shafts 3 and the first synchronous wheel 5 to rotate through the first synchronous belt 6. Then, the second synchronous wheel 7 on the rotating shaft 3 drives the second synchronous wheel 7 on the rotating rod 4 to rotate through the second synchronous belt 8, so that the rotating rod 4 rotates in the rotating groove 101. The rotating rod 4 drives the limiting block 9 on the outer wall to separate from the limiting member 11, releasing the limiting member 11 and thus releasing the limiting of the drawer 10.

[0033] When the drawer 10 is pulled outward, the drawer 10 slides in the drawer slot. The adapter gear 13 on the placement slot 1001 meshes with the rack 12 in the drive slot 102, causing the adapter gear 13 to rotate. The rotating adapter gear 13 drives the driven rod 14 to flip, causing the connecting rod 15 and the slide head 16 at the end of the driven rod 14 to slide from the receiving slot 1002 into the limiting slot 104. Then the slide head 16 is limited in the limiting slot 104.

[0034] When it is necessary to remove drawer 10 from the drawer slot, use a tool to go through the groove 1000, unscrew the bolt on the rack 12 to remove the rack 12 from the drive slot 102, and then pull drawer 10 outward to remove it.
