Ball net assembly and portable ball net

Abstract

The present application provides a ball net assembly including two upright stands and multiple ball net wires connected between the two upright stands. The upright stand includes a cylindrical shell and a positioning cover sheet fixed at two ends of the cylindrical shell, a side wall of the cylindrical shell is provided with an extension-and-contraction groove; the upright stand includes a rotating shaft located inside the cylindrical shell, two ends of multiple ball net wires pass through the extension-and-contraction groove and are connected to a side wall of the rotating shaft. When the rotating shaft rotates, the multiple ball net wires are driven to retract or extend to adjust a width of the ball net assembly; the upright stand includes a connection fastener, two ends of the connection fastener are respectively connected to the positioning cover sheets in two ball net assemblies to splice the two ball net assemblies.
