[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Example 1: Please refer to Figure 1 - Figure 4 A portable accounting teaching auxiliary device includes a base 1 and a display screen 2. A plurality of universal wheels 11 are installed at the bottom of the base 1. The base 1 also includes a cover 3, which is arranged on the top of the base 1 and is used for teachers to write knowledge points and to store and protect the display screen 2. Two columns 5 are installed on the top of the base 1. The cover 3 is slidably sleeved on the outside of the two columns 5.

[0036] The arrangement of the universal wheels 11 makes the device as a whole easy to move and highly flexible. When the device is used, the stability of the device can be ensured by controlling the universal wheels 11 to brake.

[0037] The adjusting mechanism 7 is installed on the base 1 and is used to drive the display screen 2 to move. A movable groove 6 is opened on the top of the base 1. The adjusting mechanism 7 includes a first motor 71 installed on the inner wall of one side of the movable groove 6, a bidirectional screw 72 fixedly connected to the output end of the first motor 71, two sliders 73 screwed to the outside of the bidirectional screw 72, two connecting rods 74 respectively hinged to the top of the two sliders 73, and a connecting seat 4 hinged to the other ends of the two connecting rods 74. The slider 73 is slidably connected to the inner wall of the movable groove 6, and the display screen 2 is installed inside the connecting seat 4;

[0038] When the teacher needs to use the display screen 2 for teaching, the first motor 71 is controlled to drive the bidirectional screw 72 to rotate forward, drive the two sliders 73 to move away from each other, and then drive the connecting seat 4 to move upward along the inner wall of the cover body 3 through the two connecting rods 74, so that the display screen 2 is moved out of the cover body 3. The teacher teaches by controlling the display screen 2 and writing on the display screen 2. When the display screen 2 needs to be stored, the first motor 71 is controlled to drive the bidirectional screw 72 to rotate reversely, drive the two sliders 73 to move closer to each other, and then drive the connecting seat 4 to move downward along the inner wall of the cover body 3 through the two connecting rods 74, so that the display screen 2 is moved back to the inside of the cover body 3, so that the display screen 2 can be stored, reducing the space occupied by the device when it is idle, and at the same time protecting the display screen 2.

[0039] A cleaning mechanism 8 is installed inside the cover body 3 and is used to clean the display screen 2. The cleaning mechanism 8 includes a second motor 81 installed inside the cover body 3, a one-way screw 82 fixedly connected to the output end of the second motor 81, a connecting block 83 screwed to the outside of the one-way screw 82, and an eraser 84 installed on the outer wall of the connecting block 83. The eraser 84 is a wet eraser that can ensure that no trace is left when wiping the display screen 2. The outer wall of the connecting block 83 is in sliding contact with the inner wall of the cover body 3.

[0040] By controlling the second motor 81 to drive the one-way screw 82 to rotate forward, the connecting block 83 is driven to move to the right along the inner wall of the cover body 3, and then the eraser 84 is driven to move along the surface of the cover body 3, so that the writing on the surface of the cover body 3 is completely removed. On the contrary, by controlling the second motor 81 to drive the one-way screw 82 to rotate reversely, the connecting block 83 is driven to move to the left along the inner wall of the cover body 3, and then the eraser 84 is driven to move along the surface of the cover body 3, so that the writing on the surface of the cover body 3 is completely removed.

[0041] A sealing strip 10, which is installed on the top of the display screen 2 and is used to seal the cover body 3;

[0042] After the display screen 2 is retracted into the cover body 3, the sealing strip 10 moves downward to seal the top of the cover body 3 to prevent the display screen 2 from being easily dusted when it is idle.

[0043] Example 2: Please refer to Figure 2 , Figure 4 and Figure 5 , this embodiment provides a technical solution based on the embodiment 1: a drying mechanism 9, which is installed inside the cover body 3 and connected to the cleaning mechanism 8, and is used to dry the display screen 2. The drying mechanism 9 includes a hot air blower 91 installed on the outer wall of the cover body 3, a heat preservation hose 92 installed at the output end of the hot air blower 91, and an exhaust pipe 93 installed at the other end of the heat preservation hose 92. The exhaust pipe 93 is fixed to the outer wall of the connecting block 83, and a plurality of exhaust holes are opened on the outer wall of the exhaust pipe 93 close to the display screen 2;

[0044] When the connecting block 83 moves, the hot air blower 91 is controlled to run synchronously. After the eraser 84 cleans the display screen 2, the hot air blower 91 introduces hot air into the exhaust duct 93 through the insulation hose 92. The exhaust duct 93 dries the cleaned display screen 2 through multiple exhaust holes, thereby solving the problem that the surface of the display screen 2 is wet after cleaning and affects writing.

[0045] Example 3: Please refer to Figure 6 and Figure 7 , this embodiment provides a technical solution based on the embodiment 1: a limiting mechanism 12, which is installed outside the cover body 3 and is used to limit the sealing strip 10, the limiting mechanism 12 includes a bracket 121 installed on the back of the cover body 3, an electric push rod 122 installed on the outer wall of the bracket 121, a linkage block 123 fixed to the extended end of the electric push rod 122 and a plurality of limiting rods 124 fixed to the outer wall of the linkage block 123, the other end of the limiting rod 124 extends to the inside of the cover body 3 and is slidably connected to the cover body 3, and a plurality of limiting holes 125 are opened on the back of the sealing strip 10, and the plurality of limiting holes 125 are respectively matched with the plurality of limiting rods 124;

[0046] When the teacher needs to use the cover body 3 to write knowledge points, the teacher ensures that the display screen 2 is retracted into the cover body 3, and then controls the electric push rod 122 to extend, driving the linkage block 123 to move toward the cover body 3, and then driving multiple limit rods 124 to be inserted into the corresponding limit holes 125, so that the display screen 2, the sealing strip 10 and the cover body 3 are integrated, so that when the connecting seat 4 and the display screen 2 are driven to move upward, the sealing strip 10 drives the cover body 3 to move upward synchronously along the outer wall of the column 5, so that the cover body 3 moves up to the height when the display screen 2 is used, so that the cover body 3 can be used alone, thereby effectively improving the versatility of the teaching auxiliary device.

[0047] Working principle: when the teacher needs to use the display screen 2 to teach, the first motor 71 is controlled to drive the bidirectional screw 72 to rotate forward, drive the two sliders 73 to move away from each other, and then drive the connecting seat 4 to move upward along the inner wall of the cover body 3 through the two connecting rods 74, so that the display screen 2 moves out of the cover body 3. The teacher teaches by controlling the display screen 2 and writing on the display screen 2. When the handwriting on the display screen 2 needs to be cleared during the teaching process, the second motor 81 is controlled to drive the unidirectional screw 82 to rotate forward, drive the connecting block 83 to move right along the inner wall of the cover body 3, and then drive the eraser 84 to move along the surface of the cover body 3 to completely clear the handwriting on the surface of the cover body 3. On the contrary, the second motor 81 is controlled to drive the unidirectional screw 82 to rotate reversely, drive the connecting block 83 to move left along the inner wall of the cover body 3, and then drive the eraser 84 to move along the surface of the cover body 3 to clear the handwriting on the cover body 3. The handwriting on the surface of the cover body 3 is completely removed, which solves the problem that dry erasers need to use force to clean the handwriting on the surface of the display screen 2. Rubbing hard can easily cause damage to the display screen 2, and light rubbing can easily leave residual handwriting to block the displayed content. After the wet eraser cleans the display screen 2, the display screen 2 becomes wet, which affects writing, thereby improving the cleaning effect of the display screen 2. Moreover, by automatically cleaning the display screen 2, the teacher does not need to do it manually, which does not affect the teacher's teaching. When the display screen 2 needs to be stored, the first motor 71 is controlled to drive the bidirectional screw 72 to reverse, drive the two sliders 73 to approach each other, and then drive the connecting seat 4 to move downward along the inner wall of the cover body 3 through the two connecting rods 74, so that the display screen 2 is moved back to the inside of the cover body 3, and the display screen 2 can be stored, reducing the space occupied by the device when it is idle, and at the same time playing a role in protecting the display screen 2;

[0048] When the teacher needs to use the cover body 3 to write knowledge points, the teacher ensures that the display screen 2 is retracted into the cover body 3, and then controls the electric push rod 122 to extend, driving the linkage block 123 to move toward the cover body 3, and then driving multiple limit rods 124 to be inserted into the corresponding limit holes 125, so that the display screen 2, the sealing strip 10 and the cover body 3 are integrated, so that when the connecting seat 4 and the display screen 2 are driven to move upward, the sealing strip 10 drives the cover body 3 to move upward synchronously along the outer wall of the column 5, so that the cover body 3 moves up to the height when the display screen 2 is used, so that the cover body 3 can be used alone, thereby effectively improving the versatility of the teaching auxiliary device.
