[0028] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.

[0029] like Figure 1 、 Figure 2 As shown, the material rack described in the utility model includes a frame body 1 and a plurality of protection rods 2 vertically inserted on the frame body 1. When in use, the plate 3 is placed sideways on the frame body 1, and the protection rods 2 protect the plate 3 to prevent the plate 3 from tipping over or falling.

[0030] like Figure 2 、 Figure 3 As shown, the frame 1 includes several vertically arranged T-shaped main supports, which are spaced apart. Adjacent main supports are connected by horizontal connecting rods 12. Connecting rods 12 are connected to the upper and lower parts of adjacent main supports to ensure the stability and reliability of the connection. Each main support is equipped with a support plate 13, a hanging plate 14, and a connector 15. The support plate 13 is located at the bottom of the main support, the hanging plate 14 is located at the top of the main support, and the connector 15 is located at the top of the main support. The support plate 13 is parallel to the hanging plate 14, and the hanging plate 14 is located directly above the support plate 13.

[0031] like Figure 2 、 Figure 3 As shown, the T-shaped main support is composed of two L-shaped support rods 11 back to back. The L-shaped support rod 11 includes a vertical rod portion 111 and a horizontal rod portion 112 that are perpendicular to each other. The vertical rod portions 111 of the two support rods 11 are back to back and are welded or fixedly connected by fasteners. The support rod 11 is integrally formed, formed by bending solid square steel, or cut as a whole from a thick plate with a thickness of ≥60 mm, which ensures the strength and stability of the support rod 11, improves the stability and reliability of the support, and also ensures the service life of the support rod 11. A through hole 1111 is provided on the upper part of the vertical rod portion 111 of the support rod 11, and the hanging plate 14 passes through the through hole 1111 and is fixed on the vertical rod portion 111.

[0032] The support plate 13 is arranged horizontally, with a first through-hole 131 extending through the center of the support plate 13. The back-to-back vertical rods 111 of the two support rods 11 pass through the first through-hole 131. The two sides of the support plate 13 are welded or fastened to the horizontal rods 112 of the support rods 11. Several second through-holes 132 are symmetrically formed on the surface of the support plate 13 on both sides of the first through-hole 131. The protective rod 2 is inserted through the second through-holes 132 and is welded or fastened to the support plate 13 by fasteners.
