[0020] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0021] according to Figure 1 , 2 As shown in Figures 3 and 4, a computer professional teaching auxiliary device is proposed in this embodiment, including a cabinet 1, a storage slot 2 is opened at the upper end of the cabinet 1, a flap 4 is provided on the storage slot 2, the lower end of the flap 4 is rotatably connected to the cabinet 1, and a back plate 3 is provided on the back of the cabinet 1 for supporting the flap 4 unfolded from the storage slot 2; when the teaching aids are idle, the flap 4 is stored in the storage slot 2, and when computer teaching is carried out, the flap 4 can be unfolded from the storage slot 2, and the display screen 5 can be taken out from the storage slot 2, and the back plate 3 on the back of the cabinet 1 will support the flap 4 from the back of the flap 4.

[0022] A drawer slot is provided at the front of the cabinet 1, and a drawer box is arranged in the drawer slot. The keyboard and the mouse are placed in the drawer box. When using, the lock on the drawer box is opened and the drawer box is pulled out.

[0023] Two movable plates 6 are provided on the side of the flap 4 away from the back plate 3. The movable plate 6 is slidably connected to the flap 4. A guide rail mechanism for limiting the movable plate 6 is provided at the connection between the flap 4 and the movable plate 6; the movable plate 6 can slide on the upper end of the flap 4, and the guide rail mechanism can guide the moving path of the movable plate 6 and adjust the horizontal positions of the two movable plates 6.

[0024] About the guide rail mechanism: The guide rail mechanism includes a latch plate 8 provided on both sides of the flap 4, the latch plate 8 is fixedly connected to the flap 4, and a sliding groove 9 is provided on the latch plate 8 facing the movable plate 6. Two sliding blocks 13 are provided in the sliding groove 9, and the two sliding blocks 13 are respectively fixedly connected to the two movable plates 6. The sliding block 13 is fixed on both sides of the movable plate 6, one end of which is fixedly connected to the movable plate 6, and the other end of which penetrates into the sliding groove 9 and is slidably connected to the sliding groove 9. The sliding groove 9 guides the movable plate 6 by cooperating with the sliding block 13.

[0025] The ends of the two movable plates 6 away from the flap 4 are both provided with display screens 5, and the ends of the two display screens 5 close to each other are both rotatably connected to the mounting plate 10 through movable pins 11, and a support mechanism for changing the display angle of the display screen 5 is provided between the flap 4 and the display screen 5. When conducting computer teaching, setting up two display screens 5 enables teaching staff to observe the information of people in the room while conducting teaching demonstrations, and can provide feedback more timely. The display angles of the two display screens 5 can be changed. In the process of viewing the display screens 5, the display screens 5 can be tilted and moved closer to the user through the support mechanism, so that the teaching staff has a wider viewing field.

[0026] About the support mechanism: The support mechanism includes two support rods 14 arranged on the lower end surface of the mounting plate 10, the upper end of the support rod 14 is inserted into the strip groove 18 opened at the lower end of the mounting plate 10, the strip groove 18 and the support rod 14 are slidably matched, the upper end of the support rod 14 is rotatably connected with the groove wall of the strip groove 18 through a rotating pin, and the lower end of the support rod 14 is movably matched with the positioning groove 15 opened on the upper end surface of the movable plate 6. The upper end of the movable plate 6 has a plurality of positioning grooves 15, and each positioning groove 15 is arranged equidistantly along the horizontal direction of the movable plate 6 at the upper end of the movable plate 6. When the display screen 5 is propped up, one end of the movable plate 6 is lifted, the support rod 14 is taken out of the strip groove 18, the support rod 14 is rotated, and the lower end of the support rod 14 is inserted into one of the corresponding positioning grooves 15, the support rod 14 is obliquely supported between the mounting plate 10 and the movable plate 6, and the display screen 5 is tilted and moved closer to the user through the support rod 14.

[0027] In order to improve the stability of the sliding block 13 when sliding in the sliding groove 9, the sliding block 13 is a T-shaped block, and the sliding groove 9 is a T-shaped slide groove adapted to the T-shaped block. The sliding blocks 13 at both ends of the movable plate 6 are inserted into the slide groove 9. When the movable plate 6 is pushed to move, the cooperation between the T-shaped block and the T-shaped slide groove can not only make the movable plate 6 slide horizontally, but also limit the vibration of the sliding block 13 when sliding in the slide groove 9, thereby improving the stability of the movable plate 6 when it moves.

[0028] See also Figure 4 Since the display screen 5 disposed on the upper end of the mounting plate 10 adopts a flip-cover design, when the user closes the flap 4 into the storage slot 2, in order to prevent the display screen 5 connected to the mounting plate 10 from shaking around, a spherical block 17 is disposed on the lower end surface of the mounting plate 10 away from the movable pin 11, and the spherical block 17 is engaged with the positioning hole 16 provided on the upper end surface of the movable plate 6. When the mounting plate 10 is flattened on the upper end of the flap 4, the spherical block 17 on the lower end surface of the mounting plate 10 will be engaged with the positioning hole 16 on the upper end surface of the movable plate 6. The positioning hole 16 is fixed to the mounting plate 10 by cooperating with the spherical block 17, so that the mounting plate 10 is closely attached to the upper end surface of the flap 4.

[0029] The buckle fixing method is not only convenient for fixing, but also very convenient for disassembly and assembly.

[0030] Due to the use of a snap-fit ​​method, the mounting plate 10 placed flat on the upper end surface of the movable plate 6 is fixed. In order to facilitate the user to pull the mounting plate 10, a handle 12 is provided on the upper end surface of the mounting plate 10 away from the movable pin 11. The handle 12 is fixedly connected to the mounting plate 10. By providing the handle 12 to increase the fulcrum point, the user can lift and carry the mounting plate 10 more easily.

[0031] The outer side of the handle 12 is covered with a rubber sleeve, which can prevent slipping and improve the comfort when holding.

[0032] The difference from the existing teaching auxiliary device is that two display screens 5 are provided on the flap 4. The two display screens 5 enable the teaching staff to observe the information of the people in the room while conducting teaching demonstrations, and provide feedback more timely. The two movable plates 6 are provided with display screens 5 at the ends away from the flap 4, and the ends of the two display screens 5 close to each other are rotatably connected to the mounting plate 10 through movable pins 11. A support mechanism for changing the display angle of the display screen 5 is provided between the flap 4 and the display screen 5. The display angle of the two display screens 5 can be changed. In the process of viewing the display screen 5, the display screen 5 can be tilted and moved closer to the user through the support mechanism, so that the teaching staff can have a wider viewing field.
