Referring to fig. 11, fig. 11 is a state diagram in which the first support rod 431 and the second support rod 432 are positioned on the same line.

Referring to fig. 9 and 10, the slot sidewall of the receiving slot 411 is provided with a relief through hole 412, that is, the storage frame 41 is provided with the relief through hole 412. One side of the flip plate 436, which is far away from the storage plate 42, is rotationally connected with the side wall of the avoidance through hole 412, and the avoidance through hole 412 provides an avoidance space for the rotation of the flip plate 436. Normally, the flip plate 436 is disposed in the accommodating slot 411 near one side of the storage plate 42.

Referring to fig. 9 and 10, a connection rod 434 is horizontally received in the storage frame 41, one end of the connection rod 434 is hinged to one side of the flip plate 436 near the storage plate 42, and the other end of the connection rod 434 is hinged to the middle of the second support rod 432. When the flip plate 436 receives an external force towards the first support rod 431, the flip plate 436 rotates towards the first support rod 431, and the flip plate 436 pulls the second support rod 432 to rotate, so that the support roller 433 at the end part of the second support rod 432 rotates towards the ground, and the support roller 433 is abutted against the ground. Referring to fig. 11, fig. 11 is a schematic view showing a state in which the support member 43 is changed.

Referring to fig. 9 and 10, one end of the elastic member 435 is connected to the connection bar 434, and the other end of the elastic member 435 is connected to the storage plate 42. The elastic member 435 is normally in a stretched state, so that the connecting rod 434 and the second supporting rod 432 are forced to be horizontally accommodated in the storage frame 41 by using the elastic force of the elastic member 435. Referring to fig. 11, when the cover plate 436 drives the connecting rod 434, the connecting rod 434 is away from the storage plate 42, and the connecting rod 434 and the storage plate 42 further stretch the elastic member 435. Thus, when the external force is lost from the cover plate 436, the elastic member 435 forces the connecting rod 434 and the second support rod 432 to rotate toward the storage plate 42, so that the second support rod 432 is stored in the storage frame 41.

The first sliding component 51 is matched with the commodity shelf 4 in the same way as the second sliding component 52 is matched with the commodity shelf 4. The present embodiment is explained taking the matching relationship between the second sliding component 52 and the rack 4 as an example. That is, the rack 4 is disposed on the second rail 32, and the second slider assembly 52 moves the rack 4, and the frozen goods 16 on the rack 4, onto the first rail 31.

Referring to fig. 12 and 13, when the second driving assembly 62 drives the second slider assembly 52 to move to the bottom of the shelf 4, the second lift plate 525 of the second slider assembly 52 is disposed right under the receiving slot 411 of the shelf 4. At this time, the lifting member of the second sliding component 52 drives the second lifting plate 525 to move toward the rack 4, so that the second lifting plate 525 is inserted into the accommodating slot 411.

Referring to fig. 12 and 13, at this time, the flip plate 436 disposed inside the receiving slot 411 is positioned on the moving path of the second lift plate 525. The second lift plate 525 may abut against the flip plate 436, and the second lift plate 525 may force the flip plate 436 to rotate away from the second lift plate 525, thereby forcing the second support bar 432 to rotate through the rotating flip plate 436.

Referring to fig. 14 and 15, when the second lifting plate 525 is abutted against the placement plate 42, the second lifting plate 525 moves a small distance away from the ground, so as to separate the placement frame 4 from the second i-steel 321. At this time, the second support bar 432 rotates to the vertical direction, one end of the second support bar 432 is abutted against one end of the first support bar 431, and the support roller 433 at the other end of the second support bar 432 is abutted against the ground.

Referring to fig. 4, when the supporting roller 433 is abutted against the ground, the supporting roller 433 rolls and slides on the ground at both sides of the avoidance channel 13.

Referring to fig. 6 and 7, the second sliding assembly 52 is further provided with a avoidance groove 526 that avoids the second support bar 432. When the second support bar 432 rotates, the avoidance groove 526 of the second sliding component 52 is used for avoiding the second support bar 432; so that the second support bar 432 can be rotated on a vertical plane.

To sum up: when the second sliding component 52 carries the commodity shelf 4 to move, the commodity shelf 4 is in rolling connection with the ground; thereby facilitating movement of the shelf 4 and frozen goods 16 on the shelf 4 by the second glide assembly 52.

Referring to fig. 12 and 13, when the second skid assembly 52 moves the shelf 4, and the frozen goods 16 on the shelf 4, onto the first rail 31. The second lifting plate 525 of the second sliding component 52 moves away from the rack 4, and when the second lifting plate 525 is separated from the flip plate 436, the elastic member 435 drives the second support bar 432 to rotate, so that the support roller 433 is separated from the ground. Thus, when the shelf 4 is placed in the crossing area of the first rail 31 and the second rail 32, the second support bar 432 and the support roller 433 are retracted in the shelf 4, thereby improving the stability of placing the shelf 4 on the rail 3.

The implementation principle of the portable refrigeration house provided by the embodiment of the application is as follows:

referring to fig. 2, the second driving assembly 62 pulls the second sliding assembly 52 to move to the article carrier 4 to be transported; the driving end of the second lifting piece 522 of the second sliding component 52 is abutted against the bottom of the storage rack 4, and the storage rack 4 is lifted up, so that the storage rack 4 is separated from the second track 32; then, the second driving assembly 62 drives the second sliding assembly 52 to move toward the first track 31.

When the second sliding component 52 carries the rack 4 to the first rail 31, the driving end of the second lifting member 522 of the second sliding component 52 moves toward the ground, so that the bottom of the rack 4 abuts against the first rail 31 and the second rail 32, and the second driving component 62 pulls the second sliding component 52 back onto the second rail 32.

Next, the first driving component 61 pulls the first sliding component 51 to move to the bottom of the rack 4, and the first driving component 61 lifts the rack 4, so that the rack 4 is separated from the first rail 31. The first driving assembly 61 drives the first sliding assembly 51 to move towards the entrance 12 of the storehouse 1, so that the goods 16 on the shelf 4 are placed at the entrance 12 of the storehouse 1 in advance, workers can conveniently enter and exit the goods 16, and the situation that water vapor in the outside enters the refrigerator is reduced.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
