When the rack 200 is in the accommodating position, the stop bar 600 is abutted with the stop bar 611 on one side, and when the rack 200 is in the limit unfolding position, the stop bar 600 is abutted with the stop bar 611 on the other side, so that the limit bar 600 is prevented from being blocked due to the fact that the swing range of the stop bar 600 is large and the limit post 610 is separated from the limit rail 500.
Further, in an embodiment of the present invention, a reset guide 700 is further disposed on the inner side of the refrigeration door 100, the reset guide 700 includes a slope surface ascending along the rotation direction of the shelf 200 from the storage position to the unfolding position, the shelf 200 is provided with a supporting portion 230 supported on the slope surface, the supporting portion 230 can slide on the slope surface, and the shelf 200 rotates to drive the supporting portion 230 to climb or slide down along the slope surface.
In the present embodiment, when the user applies an external force to the shelf 200 to drive the shelf 200 to rotate from the storage position to the extended position, the support portion 230 at the bottom of the shelf 200 climbs along the slope, and the shelf 200 slowly rises, and if the user releases the shelf 200 at this time, the shelf 200 tends to slide down along the slope of the reset guide 700 under the action of gravity. If the rack 200 is not unfolded to the limit unfolding position at this time, the limit posts 610 are matched with the ratchets in the unfolding track 510, and at this time, the rack 200 is suspended at the limit unfolding position under the stop of the ratchets. If the rack 200 is rotated to the limit unfolding position, the limit posts 610 enter the restoring rail 520 from the unfolding rail 510, and the rack 200 slides down the slope of the restoring guide 700 under the action of gravity, so as to automatically restore to the storage position.
In this way, by providing the reset guide 700 to store gravitational potential energy when the shelf 200 is unfolded, the shelf 200 can be automatically restored to the storage position from the unfolded position under the action of the gravitational potential energy, thereby facilitating the use of users.
Further, the reset guide 700 is disposed on the lower rotating shaft seat 320, and the slope is arc-shaped with the rotating shaft 340 as the center.

At this time, the rack 200 presses the elastic element 800, the elastic force of the elastic element 800 drives the rack 200 to rotate in the opposite direction, and the rack 200 drives the stop lever 600 to move from the relief groove 551 into the opposite locking groove 561, so as to realize locking.
Further, the connection surface of the extension rail 510 and the return rail 520 at one end of the accommodating position is in a step shape, the connection surface comprises a first step surface 552 and a second step surface 562, the first step surface 552 is higher than the second step surface 562, the first step surface 552 is connected with the return rail 520, two ends of the second step surface 562 are respectively connected with the first step surface 552 and the extension rail 510, the first step surface 552 and the abdication groove 551 form an abdication part 550, and the second step surface 562 and the locking groove 561 form a locking part 560. Under the action of the elastic force of the elastic element 800, after the limit post 610 moves into the locking groove 561 from the abdication part 550, the limit post 610 cannot rebound to the locking part 560 any more, and cannot swing at will, so that the locking is more stable due to the step shape between the abdication part 550 and the locking part 560.
Further, the first step surface 552 is lower than the track surface of the return track 520 and the second step surface 562 is higher than the deployment track 510. The opening of the relief groove 551 is smaller than the opening of the locking groove 561, the first step surface 552 and the second step surface 562 are fan-like shapes, two sides of the first step surface 552 are respectively connecting lines between two ends of the relief groove 551 and the end of the locking groove 561, which is close to the return track 520, and two sides of the second step surface 562 are respectively connecting lines between two ends of the locking groove 561 and the end of the relief groove 551, which is close to the unfolding track 510.
The step between the first step surface 552 and the restoring track 520 may increase gravitational potential energy, and meanwhile, the connecting wall between the first step surface 552 and the restoring track 520 may guide and limit the limit post 610, so as to guide the limit post 610 into the locking groove 561, thereby avoiding the limit post 610 from restoring to the restoring track 520 under the action of the elastic force of the elastic element 800.
When the user wants to rotate the rack 200 out of the storage position, the user can press the rack 200, the limit post 610 is disengaged from the locking groove 561, and meanwhile, the elastic element 800 at the rear side of the rack 200 is compressed to generate elastic force for driving the rack 200 to rotate towards the unfolding position, the connection side wall between the first step surface 552 and the second step surface 562 guides the limit post 610, the limit post 610 moves into the unfolding track 510 by the locking part 560 to unlock, and the user can continuously pull the rack 200 to rotate towards the unfolding position.
