Problems solved by technology

[0002] Today, multimedia teaching has been popularized in various classroom teaching. For classrooms without curtains, it is still a troublesome thing to install and fix the curtains. The traditional bracket-type curtains are difficult to stick to the blackboard because the brackets take up space. , even if the distance between the students and the screen is shortened, they are easily blown by the flowing air, which cannot achieve the best projection effect

Abstract

Disclosed is a piece of magnetic positioning multimedia teaching curtain. The magnetic positioning multimedia teaching curtain comprises a piece of curtain, magnet shells, pull rods, magnets and rubber rings; the magnetic positioning multimedia teaching curtain is characterized in that the curtain is provided with a first transverse rack while an elastic thin film is arranged on the other edge; the elastic thin film is connected with a second transverse rack; the magnet shells are arranged on the first transverse rack and the second transverse rack; a groove is formed in each magnet shell; each pull rod is arranged in the corresponding groove; one end of each pull rod is fixed in the middle of the corresponding groove while the other end of the pull rod and a handle are wedded together; the magnets are fixed in the corresponding magnet shells; the rubber rings are arranged around the magnets; the first transverse rack and the second transverse rack are at least provided with more than two magnets separately; the first transverse rack and the second transverse rack are made from a hard material; the bottom surfaces of the magnets are flush with the bottom surfaces of the first transverse rack and the second transverse rack; the rubber rings protrude below the magnets; the rubber rings are made from a soft rubber material with relatively high friction coefficient; and the pull rods can turn over in the corresponding grooves for a certain degree.

Description

technical field [0001] The invention relates to a multimedia teaching tool, in particular to a magnetic positioning multimedia teaching curtain. Background technique [0002] Today, multimedia teaching has been popularized in various classroom teaching. For classrooms without curtains, it is still a troublesome thing to install and fix the curtains. The traditional bracket-type curtains are difficult to stick to the blackboard because the brackets take up space. , even if the distance between the students and the screen is shortened, they are easily blown by the flowing air, which cannot achieve the best projection effect. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention provides a magnetic positioning multimedia teaching screen. [0004] The technical scheme adopted by the present invention is as follows: a magnetic positioning multimedia teaching curtain, comprising a curtain, a magnet shell, a pull rod, a magnet, and an apro...
