Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1-Figure 5, a virtual reality technology teaching auxiliary device, including a box body 1, the top of the box body 1 is rotatably connected to two symmetrically distributed cover plates 3, both sides of the box body 1 are provided with observation windows 2, a second placement plate 6 is arranged in the box body 1, a plurality of second fixing blocks are fixed on the upper surface of the second placement plate 6, one side of the plurality of second fixing blocks are rotatably connected to a second connecting frame 9, one end of the second connecting frame 9 is rotatably connected to two first placement plates 5, the tops of the two first placement plates 5 are fixed with a plurality of first fixing blocks 12 by bolts, one side of the plurality of first fixing blocks 12 are rotatably connected to a connecting shaft 11, one end of the connecting shaft 11 is welded with a first connecting frame 4, and the other end of the first connecting frame 4 is rotatably connected to another first placement plate 5, and so on, multiple layers are set according to actual needs, and glasses and components are classified and stored. When the bottom end of the first connecting frame 4 moves out of the box body 1, the first placement plate 5 above it can be rotated to expand the space of the next layer, so as to facilitate the taking and placing of items in the lower layer, improve the storage effect of the device, and facilitate the observation of students.

[0027] In order to realize the upward movement of the multi-layer structure, the bottom of the second placement plate 6 is rotatably connected to two first connecting rods 7, and the bottom inner wall of the box body 1 is rotatably connected to two second connecting rods 14, and the central parts of the first connecting rod 7 and the second connecting rod 14 are rotatably connected, and a connecting plate 16 is rotatably connected between the two first connecting rods 7, and the bottom inner wall of the box body 1 is fixed with a fixing plate 13 by bolts, and a motor is fixed to one side of the fixing plate 13 by bolts, and the output shaft of the motor passes through the fixing plate 13 and is welded with a screw rod 18, and the screw rod 18 is threadedly connected to the connecting plate 16, and two symmetrically distributed guide rods 19 are fixed by bolts between the inner walls on both sides of the bottom of the box body 1, and the guide rod 19 passes through the connecting plate 16 and is slidably connected to the connecting plate 16, and the motor is started, and the motor drives the screw rod 18 to rotate. The rotation of the screw rod 18 can make the connecting plate 16 move horizontally under the action of the guide rod 19, thereby driving the first connecting rod 7 to rotate, and then driving the second connecting rod 14 to rotate, so that the second placement plate 6 can move upward smoothly, without manually lifting the multi-layer structure, thereby improving the labor-saving effect of the device.
