The disposable dustproof net 4 is a protective member in the entire dustproof net, and is used to protect the ground below the entire dustproof net to reduce the occurrence of dust on the ground below under the influence of the external environment. The connecting outer frame 41 located at the top edge of the disposable dustproof net 4 is used to provide a carrier for supporting the disposable dustproof net 4. The first limiting component 2 located at the top of the connection between the first support rod 11 and the second support rod 12 is used to The dust net 4 is positioned at multiple points on the top of the outer support frame 1, wherein the connecting rod 21 in the first limiting assembly 2 is used to provide a carrier for connecting the limiting seat 22 and the connection points between the first support rod 11 and the second support rod 12, and the limiting seat 22 is used to provide a carrier for connecting the limiting hook 23, and the limiting hook 23 is used to limit the disposable dustproof net 4, wherein when the disposable dustproof net 4 is laid on the top of the outer support frame 1, the area of the disposable dustproof net 4 located at the top of the first limiting assembly 2 can be pressed downward so that the disposable dustproof net 4 passes through the upper end of the first limiting assembly 2, and the through groove of the disposable dustproof net 4 is limited by the limiting hook 23, and the multi-point limiting of the disposable dustproof net 4 by several first limiting assemblies 2 is completed. The overall limiting of the disposable dustproof net 4 on the top of the outer support frame 1 is completed, and the disposable dustproof net 4 can be easily disassembled on the outer support frame 1 through the card-type limiting method.
[0017] The bottom of the outer frame 41 is fixedly connected to a limited rubber column 421, and the bottom of the limited rubber column 421 is fixedly connected to a mounting column 42.
