[0021] To make the technical solution of the present utility model clearer and more definite for those skilled in the art, the present utility model will be further described in detail below in conjunction with embodiments and drawings. However, the implementation manners of the present utility model are not limited thereto.

[0022] As Figures 1 - 3 shown, a heavy-duty shelf that is easy to adjust provided in this embodiment includes a main frame 1. The main frame 1 is a split symmetric structure. Support seats 2 are installed on the opposite sides of the two groups of main frames 1. The support seats 2 can support the bearing plate 3. A bearing plate 3 is provided at the top of the support seat 2. The bearing plate 3 can carry goods. A reinforcing plate 4 is provided at the bottom of the bearing plate 3. The reinforcing plate 4 can improve the strength of the bearing plate 3. An adjusting mechanism 5 is installed at the bottom of the reinforcing plate 4. The adjusting mechanism 5 includes a base 501 located below the reinforcing plate 4. The base 501 can drive one of the connecting seats 502 to move. Multiple groups of connecting seats 502 are installed on the opposite sides of the reinforcing plate 4 and the base 501. The connecting seats 502 can connect the connecting rods 503. And a connecting rod 503 is rotatably connected between each group of bases 501. The connecting rod 503 is connected to the connecting seat 502. During the movement of the base 501, both ends of the connecting rod 503 can rotate along the connecting seat 502, so as to adjust the vertical height of the reinforcing plate 4. A bidirectional lead screw 504 is rotatably connected to the middle part inside the base 501. The bidirectional lead screw 504 can drive the base 501 to move horizontally. And guide rods 505 are slidably connected to both sides of the bidirectional lead screw 504 inside the base 501. The guide rods 505 can guide the base 501.

[0023] As Figures 1 - 2 shown, the bottom end of the bearing plate 3 is of a concave structure, and the size of the reinforcing plate 4 is smaller than that of the bearing plate 3, which is convenient for the reinforcing plate 4 to abut against the top and bottom of the bearing plate 3.

[0024] As Figures 1 - 2 shown, positioning seats 9 are symmetrically installed on both sides of the bottom end of the bearing plate 3. The outer sides of the positioning seats 9 abut against the side walls of the support seats 2. During use, the positioning seats 9 can abut against the support seats 2 to limit the bearing plate 3.

[0025] As Figures 1 - 3 shown, one end of the bidirectional lead screw 504 penetrates through the positioning seat 9, and a hand wheel 6 is installed at one end of the bidirectional lead screw 504 extending to the positioning seat 9. The hand wheel 6 has an eccentric handle for holding, which is convenient for the staff to rotate the bidirectional lead screw 504 by using the hand wheel 6.

[0026] As Figure 2 shown, limiting seats 7 are fixed on the outer sides of the reinforcing plates 4. One end of the limiting seat 7 is of a convex structure.

[0027] As Figure 2As shown in the figure, a limiting groove 8 is provided on the side wall of the bearing plate 3 corresponding to the limiting seat 7, and the limiting seat 7 is slidably connected to the bearing plate 3 through the limiting groove 8, and the movement of the reinforcing plate 4 can be guided through the cooperation of the limiting seat 7 and the limiting groove 8 during the movement process.

[0028] As Figures 1 - 2 shown in the figure, the support seat 2 has a triangular structure, and both the support seat 2 and the positioning seat 9 are hollow structures, which can provide high-strength support for the bearing plate 3 through the triangular support seat 2 and reduce the overall weight of the heavy-duty shelf.

[0029] The working principle of this device: When this device is specifically used, the staff places the bearing plate 3 on the corresponding support seat 2 according to the bearing requirements of the goods. The triangular support seat 2 provides high-strength support for the bearing plate 3, and the bearing plate 3 is limited by the positioning seat 9 abutted against the support seat 2 to prevent the bearing plate 3 from shifting. After the placement is completed, the staff rotates the bidirectional lead screw 504 using the handwheel 6. The bidirectional lead screw 504 can drive the two groups of bases 501 to move synchronously. During the movement of the bases 501, the connecting rod 503 can rotate along the connecting seat 502, so as to adjust the vertical position of the reinforcing plate 4 until the top of the reinforcing plate 4 abuts against the bottom of the top of the bearing plate 3. Then the goods are placed on the bearing plate 3, and the strength of the bearing plate 3 is increased through the reinforcing plate 4, avoiding the bending of the middle part of the bearing plate 3 during the process of carrying goods, preventing damage, and improving the service life. During the vertical movement of the reinforcing plate 4, the limiting seat 7 can move along the limiting groove 8 to guide it.
