A plurality of connecting seats for connecting a bed surface or a table surface are installed on the rack body. A length-adjustable stabilizing rod is connected to the rack body.

[0005] When the folding rack is in use, the entire rack body is unfolded outwards, the space enclosed by the rack body increases, and the height of the rack body decreases. When it is necessary to connect the bed surface to be used as a folding bed, the bed surface is connected to the connecting seat on the rack body to form a folding bed. When it is necessary to connect the table surface to be used as a folding table, the table surface is connected to the connecting seat on the rack body to form a folding table. The stabilizing rod is connected to the rack body. After the folding rack is unfolded in place, the stabilizing rod is connected to the rack body to position the rack body, so that the entire rack body is in a stable state. At this time, after the bed surface or the table surface is subjected to the gravity, the rack body can stably support without moving. In many cases, the use heights of the folding bed and the folding table are different. Generally, the use height of the folding table is higher than that of the folding bed. Therefore, the length of the stabilizing rod can be adjusted to meet the use requirements of different support heights of the rack body. When the folding rack is folded, the entire rack body is retracted inwards, and all the folding units are closed together, occupying a small space and being convenient for folding operation.

[0006] The folding rack of this patent application is convenient to fold and occupies a small space after folding. The folding rack has various functions and can be applied to both the folding bed and the folding table.
