DETAILED DESCRIPTION

[0018] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0019] A device for education and training, comprising a base 1, vertical tubes 2 are arranged on both sides of the top of the base 1, wherein a T-shaped rod 3 is arranged inside the vertical tube 2, and the size of the vertical end of the T-shaped rod 3 is adapted to the size of the internal opening of the vertical tube 2, and a mounting frame 4 is suspended between two groups of T-shaped rods 3, a display screen 5 is arranged inside the mounting frame 4, wherein a locking mechanism 6 for fixing the display screen 5 is arranged on the mounting frame 4, and the two groups of vertical tubes 2 located below the mounting frame 4 are connected by a connecting plate 7, and a screw 8 is fixed on the connecting plate 7 through a rolling bearing 9, wherein a screw 10 connected to the bottom of the mounting frame 4 is screwed in the screw 8;

[0020] The mounting frame 4 is composed of a back plate and a rectangular frame 41 arranged on the front side of the back plate, and the locking mechanism 6 includes a groove 61 arranged on the inner side wall of the vertical end of the rectangular frame 41, wherein a pressure rod 62 located on the front side of the display screen 5 is obliquely arranged in the groove 61, and one end of the pressure rod 62 is fixed in the groove 61 through a rotating shaft 63, wherein a sliding opening 64 for accommodating the other end of the pressure rod 62 is arranged on the side wall of the horizontal end of the rectangular frame 41, and one end of the groove 61 is connected to the corresponding sliding opening 64, and a spring 65 connected to the side wall of the groove 61 is also arranged on the back of the pressure rod 62.

[0021] like Figure 2 As shown, a circular groove for accommodating the bottom end of the spiral tube 8 is provided on the top of the base 1, wherein the spiral tube 8 is provided with a handle.

[0022] In this embodiment, an operation opening and a ventilation hole are arranged on the side wall of the back plate.

[0023] like Figure 2 , 3 As shown, a vertical plate 11 is arranged on one side of the vertical tube 2 above the connecting plate 7, wherein a plurality of groups of mounting holes 12 are arranged in parallel up and down on one side of the vertical plate 11, and pins 13 embedded in one group of mounting holes 12 are arranged on both sides of the bottom of the mounting frame 4, and the vertical plate 11 is arranged between the mounting frame 4 and the corresponding vertical tube 2, wherein scale values ​​are arranged on the surface of the vertical plate 11.

[0024] The working principle of the present invention is as follows: when the height of the display screen 5 needs to be adjusted, the screw tube 8 only needs to be rotated to make it rotate on the rolling bearing 9, and it will also rotate on the screw rod 10, thereby driving the screw rod 10 to drive the mounting frame 4 and the display screen 5 to move up and down, so as to achieve the purpose of adjusting the height of the display screen 5, and at the same time, the display screen 5 and the mounting frame 4 are suspended and fixed at a specified height;

[0025] In the above process, the mounting frame 4 will drive the T-shaped rod 3 to slide up and down in the vertical tube 2, so as to prevent the mounting frame 4 moving up and down from rotating under the influence of the screw 10 of the screw tube, and when the height of the mounting frame 4 is adjusted, the latch 13 is moved so that its end is inserted into the corresponding mounting hole 12, so as to further support and fix the bottom of both ends of the mounting frame 4, so as to improve the stability of the mounting frame 4 and the display screen 5;

[0026] When installing the display screen 5, it is only necessary to move the end of the pressure rod 62 located in the sliding opening 64 to make it rotate around the rotating shaft 63 as the center, and at the same time compress the spring 65 to make it shrink, so that the pressure rod 62 finally slides out of the opening of the rectangular frame 41 and embeds into the groove 61 and the sliding opening 64. At this time, the display screen 5 can be embedded in the mounting frame 4. The back plate supports and fixes the back of the display screen 5 while also fixing it through the connecting component. At this time, the pressure rod 62 is released to make it slide to the front side of the display screen 5 under the expansion force of the spring 65, and the pressure rod 62 is pressed against the front corner of the display screen 5 to prevent it from sliding out of the front opening of the rectangular frame 41.

[0027] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
