Simple Screen

Abstract

A simple screen includes a frame and a panel. The frame includes cross rods, vertical rods, and connection joints. The connection joint includes an upper rotating base and a lower rotating base. A connection rod is disposed on the upper rotating base and/or the lower rotating base, the cross rod is in a shape of a cylinder and sleeved on the connection rod, and the cross rod is detachably connected to the connection rod. A central part of the upper rotating base and a central part of the lower rotating base are each provided with a through-hole, a locking pin penetrates through the through-hole, and the locking pin is connected to the vertical rod after penetrating through the through-hole. The screen is convenient to transport. One piece of the screen may be used alone or more pieces of the screens are used together. The screens may be folded.
