As shown in Figures 1-9, this specific embodiment adopts the following technical solutions: it includes a long support rod 1, a foot 2, a fixing hole 2-1, a cloth cover 3, a hole 3-1, a roller 4 and a short support rod 5. The main body of the exhibition board frame is mainly composed of two long support rods 1 placed in parallel, and a short support rod 5 is installed on the rear side of the long support rod 1, and the short support rod 5 and the long support rod 1 A cloth cover 3 is arranged between, and a cylindrical sleeve hole is provided at the connection between the cloth cover 3 and the long support rod 1 and the short support rod 5, for the support of the cloth cover 3 and the long support rod 1 and the short support rod 5 connection, the center of the cloth cover 3 is provided with a hole 3-1, the hole 3-1 is in the shape of a rectangle, and a roller 4 is installed between the two parallel long support rods 1, and the roller 4 The two are a group, there are two groups of upper and lower groups, and the upper and lower ends of the poster are respectively fixed. The lower end of the long support rod 1 is equipped with a foot 2, and several fixing holes 2-1 are provided on the foot 2, which is convenient for the long support rod. The adjustment of 1 is fixed.

The long support rod 1 includes a first support rod 1-1, a connecting rod 1-2, a third support rod 1-3 and a mounting hole 1-3-1, and the first support rod 1-1 and the second support rod 1-1 The three support rods 1-3 are respectively threadedly connected with the two ends of the connecting rod 1-2. When in use, they can be selectively disassembled and installed according to the height of the long support rod 1. The upper end of the third support rod 1-3 is provided with a mounting Hole 1-3-1, one end of the short support rod 5 is inserted into the upper end of the long support rod 1 through the installation hole 1-3-1.

The drum 4 includes a small cylinder 4-1, a middle cylinder 4-2, a large cylinder 4-3 and a screw cap 4-4, and the two sides of the small cylinder 4-1 are respectively connected with two middle cylinders 4-2, Both ends of the small tube 4-1 are provided with a first annular protrusion 4-1-1, one end of the middle tube 4-2 is provided with a second annular protrusion 4-2-1, and the inner wall of the other end is provided with a The first annular stopper 4-2-2, through the first annular protrusion 4-1-1 and the first annular stopper 4-2-2, the small tube 4-1 and the middle tube 4-2 can be Sliding connection, and will not fall off, the outer side of the middle tube 4-2 is connected with the large tube 4-3, the inner wall of one end of the large tube 4-3 is provided with a second annular stopper 4-3-1, and the other end penetrates The hole 3-1 on the cloth cover 3 is threadedly connected with the screw cap 4-4, through the second annular protrusion 4-2-1 and the second annular stopper 4-3-1, the middle cylinder 4-2 and the large cylinder 4 -3 can be slidably connected and will not fall off.
