Abstract

The invention belongs to the automatic control teaching technology field, and especially relates to a curtain support for automatic control teaching. For an existing projection curtain support, curtain switching is inconvenient, a curtain is easy to mildew, and adjustment is inconvenient. Aiming at the above problems, the invention provides the following scheme. A winding drum is included. Telescopic rod components are rotatably connected to two ends of the winding drum. Round blocks are fixed to one ends, far away from the winding drum, of the two telescopic rod componets through bolts. Outerwalls of opposite sides of the two round blocks are rotatably connected with a same transverse shaft, a supporting plate is welded to one side of the transverse shaft, a rectangular hole is arrangedin the supporting plate, a balance weight water tank is clamped to the inner wall of the rectangular hole, a section of the winding drum is a structure shaped as a number eight, and two winding cavities are arranged in the winding drum. In the invention, different types of curtains can be accommodated conveniently, operation is simple, switching is convenient, the curtain can be heated by combining an arranged electric baking lamp tube, the curtain is ensured to be dry, the curtain is prevented from mildewing, and a service life of the curtain is prolonged.

Description

technical field [0001] The invention relates to the technical field of automatic control teaching, in particular to a curtain bracket for automatic control teaching. Background technique [0002] There are semi-automatic and full automation in automation control. Automation control is a kind of integrated control technology and theory of mechanical and electrical automation in the production fields such as modern industry, agriculture, and manufacturing. Automation control is also an important subject, and projection screen brackets are needed in the teaching process. [0003] The existing projection screen bracket is inconvenient to switch the screen, the screen is easy to mildew, and it is inconvenient to adjust. Therefore, an automatic control teaching screen bracket is proposed. Contents of the invention [0004] Based on the technical problems that the existing projection screen support is inconvenient to switch the screen, the screen is easy to mildew and inconvenie...
