The invention relates to the technical field of English teaching auxiliary devices, and discloses a foldable English teaching frame structure which comprises a teaching board. A fixing rod is fixedly installed on the surface of the teaching board, an adapter hole is formed in the surface of the fixing rod, a rotating rod is rotatably connected to the inner wall of the adapter hole, supporting rods are welded to the two ends of the rotating rod, a connecting rod is welded to the side surface of each supporting rod, and the surface of the rotating rod is rotatably connected with a reducing sleeve. According to the foldable English teaching frame structure, through the arrangement of the adapter holes, the supporting rods, the supporting legs and the fixing rods can be folded and contracted through the rotating rods and the adapter holes so that the size of the teaching frame during moving and carrying is reduced, and through the arrangement of the inserting rods and the clamping connection of the inserting rods and the clamping grooves, the supporting rods can be stably connected with the fixing rods after being folded; and the movement range of the supporting legs is set near the supporting rods by arranging the bridles so that the supporting rods and the supporting legs form a triangular supporting structure, and the stability of the teaching frame is improved.
Description
technical field [0001] The invention relates to the technical field of English teaching auxiliary devices, in particular to a foldable English teaching frame structure. Background technique [0002] The English teaching stand is a movable auxiliary teaching device. In the process of English teaching, it is usually necessary to quote a large number of extracurricular vocabulary and pictures to expand the teaching materials, so as to deepen the impression of English learning and improve learning efficiency. [0003] Most of the existing English teaching racks, in order to improve their stability, the overall structure of the bracket part is relatively large, and many people need to work together to carry it during teaching, which is too labor-intensive, and because the bracket parts of most teaching racks are welded and fixed, so that When carrying out English teaching again, it is necessary to change the carrying angle many times before moving the English teaching frame to th...
