[0035] The horizontal section 1f1 is provided with a positioning protrusion 1g, the bottom surface of the bottom beam 3d is provided with a positioning groove 3e, the positioning protrusion 1g is embedded in the positioning groove 3e, and the position of the front door frame 3 relative to the bottom plate 1 is consistent after each assembly. The side surface of the reinforcing rib 2b is in contact with the side surface of the left frame 3a and the right frame 3b of the front door frame 3, has a positioning function, and ensures that the position of the side plate 2 relative to the bottom plate 1 and the front door frame 3 is consistent after each assembly. As shown in Figure 7 The left frame 3a and the right frame 3b are completely embedded in the first positioning groove 2a, so that the left frame 3a and the right frame 3b are completely coincided with the side plate 2, the distance between the side surface of the door frame hole and the inner side of the side plate 2 is significantly reduced, in other words, the left frame 3a and the right frame 3b will not affect the taking and placing of articles.

[0036] The front door frame 3 is provided with door leaves 5, the number of door leaves 5 is two as shown in the drawings, the door leaves 5 are in sliding connection with the top beam 3c and the bottom beam 3d, and horizontal movement of the door leaves 5 can make the door frame hole of the front door frame 3 in the open or closed state. The number of door leaves 5 can be adaptively adjusted according to actual conditions, such as 1 or 3 or 4; the mounting mode of the door leaves 5 can also be adaptively adjusted, such as rotating connection between the door leaves 5 and the top beam 3c and the bottom beam 3d.

[0037] The top of the front door frame 3 is also connected with the top of the side plate 2 through a second corner code 7, a plurality of second limiting grooves are formed on the second corner code 7, and the top region of the side plate 2 and the top region of the front door frame 3 are embedded in the second limiting grooves. The second corner code 7 not only limits the outward swinging of the side plate 2 relative to the front door frame 3, but also improves the connection strength of the front door frame 3 and the side plate 2.

[0038] Embodiment two: The structure and principle of this embodiment are basically the same as those of embodiment one, and the same parts will not be described again. Only the different parts will be described. The front door frame 3 does not have a bottom beam part 3d, and is composed of a left frame part 3a, a right frame part 3b and a top beam part 3c. The left edge part 1b and the right edge part 1c of the bottom plate 1 are provided with vertically arranged second positioning grooves 1f. The bottom section of the left frame part 3a is inserted into the second positioning groove 1f on the left edge part 1b, and the bottom section of the right frame part 3b is inserted into the second positioning groove 1f on the right edge part 1c.

[0039] The bottom of the door leaf 5 is connected with the front edge part 1e of the bottom plate 1, and the top of the door leaf 5 is connected with the top beam part 3c of the front door frame 3.
