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 Figures 1-5, the utility model provides a technical solution: a sand table for oral English training, including an outer frame 1, a push-pull grid 7 and a tripod 12, the outer frame 1 passes through the first rotating shaft 2 and the glass cover 3 connected, and a separation groove 4 is provided between the outer frame 1 and the glass cover plate 3, and a first fixer 5 is installed on the upper surface of the outer frame 1, and the outer frame 1 is connected to the first fixer 5 by pasting and connecting, And the quantity of the first fixer 5 is 4, and it is symmetrically distributed about the center of the upper surface of the outer frame 1, the glass cover plate 3 is a rotating structure, and its rotation angle range is 0-90°, the first fixer 5 is Rotation structure, and its rotation angle range is 0-90°, setting the first fixer 5 can fix the glass cover 3 and the outer frame 1 to prevent the internal items from falling. If the glass cover 3 needs to be opened, turn the first The fixer 5 is enough, the push-pull grid 7 is connected with the outer frame 1 through the slide rail 15, and the electric telescopic rod 9 is fixed inside the push-pull grid 7, and the push-pull grid 7 is connected with the lifting grid 8, and the push-pull grid 7 is connected with the outer frame 1 Constitutes a sliding structure, and the push-pull grid 7 is connected to the electric telescopic rod 9 by welding, and the electric telescopic rod 9 is connected to the lifter 8 by welding, so that we can easily pull the push-pull grid 7 from the outer frame 1 Or put it back, when using the lifting frame 8 display function, its electric telescopic rod 9 makes the lifting frame 8 parallel to the upper surface of the outer frame 1 to obtain a complete plane, and the display effect is better. Two fixers 6, and the lower surface of the outer frame 1 is equipped with a connecting rod fixing block 10, the second fixer 6 is a rotating structure, and its rotation angle range is 0-90°, and the number of the second fixer 6 is 4 At the same time, the second fixer 6 is symmetrically distributed front and back with respect to the vertical center line of the outer frame 1. The second fixer 6 is symmetrically distributed, and the second fixer 6 fixes the push-pull grid 7 in the outer frame 1, ensuring that the push-pull grid is in the process of transportation. 7 stability, the tripod 12 is connected with the outer frame 1 through the second rotating shaft 11, and the tripod 12 is fixed with a lever block 13, and the tripod 12 is connected with the connecting rod 14 through the snap rod block 13. It is a rotating structure, and its rotation angle range is 0-90°, and the tripod 12 and the rod block 13 are an integrated structure, and the rod block 13 is connected with the connecting rod 14 in an engaging manner, and the connecting rod 14 is Disassemble the structure, the connecting rod 14 prevents the tripod 12 from moving in the horizontal direction, making the tripod 12 more stable, and when the tripod 12 is not used, the connecting rod 14 can be stored in the connecting rod fixing block 10, avoiding The problem that the connecting rod fixing block 10 is accidentally lost.

Working principle: First, turn the first holder 5 by 90° so that the first holder 5 is parallel to the outer frame 1, then turn the glass cover 3 upward by 90° along the first rotating shaft 2, and put the English training and display tools into the In the separation groove 4, turn the glass cover plate 3 downward along the first rotating shaft 2 by 90°, then turn the first holder 5 inward by 90°, and fix the glass cover plate 3 on the outer frame by the first holder 5 1, then turn the second holder 6 downward until the second holder 6 is vertically downward, pull the push-pull grid 7, and the push-pull grid 7 will slide outward along the electric telescopic rod 9 until the push-pull grid 7 Pull out the outer frame 1, then put the English training display tool into the lifting frame 8, when the second fixer 6 is needed for display, the lifting frame 8 is raised by the electric telescopic rod 9 until the upper surface of the lifting frame 8 is in contact with the outer frame 8. The upper surface of the frame 1 is parallel. When the display of the separation groove 4 meets the display quantity requirements, it will be retracted in the same way, and the second holder 6 will be rotated upward so that the second holder 6 is parallel to the ground, and the push-pull grid 7 is fixed on the outer frame. 1. Inside, when the display sand table is not needed, the connecting rod 14 can be lifted upwards so that the connecting rod 14 is separated from the rod block 13, and then the tripod 12 is turned inward by 90°, and finally the connecting rod 14 is stuck on the connecting rod block 13. It can be stored on the rod fixing block 10, which is the usage method of this oral English training display sand table.
