Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1, the utility model provides a kind of technical scheme: a kind of wall chart stand for English teaching, comprises support leg 1 and frame 2, and the top level of described support leg is provided with through hole 3, and the bottom end of frame and support leg The contact point can be rotated to adjust the angle. The middle part of the upper surface of the leg is vertically provided with a threaded hole 4, and the lower end of the threaded hole 4 runs through the upper side wall of the through hole. The threaded hole is internally threaded with a bolt 5, and the bolt and The matching arrangement of threaded holes can fix the frame after the angle adjustment. The lower end of the legs is provided with a balance seat 6 to keep the frame in balance. The outer sides of the two ends in contact with the through hole are fixedly installed with limit sleeves 7 to limit the horizontal movement of the frame in the through hole. Sliders 8 are installed on the vertical bars on the left and right sides of the frame to slide symmetrically on the frame. , between the sliders, an adjusting rod 9 is installed horizontally, and the adjusting rod can adjust the distance between the up and down symmetrical wall chart devices 10 along with the sliding sliding to adapt to English pictures of different sizes and specifications.
