[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-Figure 10 , an intelligent mathematics teaching auxiliary device for mathematics teaching, including a frame 5, the middle section of the frame 5 is divided into two left and right spaces by an intermediate plate 3, the inner walls of the two spaces are provided with slideways, two blackboards 2 are slidably installed on the slideways in the front and rear positions, and mobile racks 4 are provided at both ends of the frame 5. One side of the blackboard 2 is connected to the mobile rack 4 through a plurality of first limiting mechanisms 10, and the other side of the blackboard 2 is provided with a plurality of second limiting mechanisms 9; The upper end of the middle plate 3 is fixedly connected to a crossbeam 6, to which an auxiliary rod 8 is fixedly connected, on which a curtain 1 is slidably suspended, a driving mechanism is arranged in the auxiliary rod 8, a reel 7 is arranged at the upper end of the curtain 1, the reel 7 is connected to the driving mechanism, and the driving mechanism is used to drive the reel 7 to move relative to the auxiliary rod 8.

[0020] Both ends of the reel 7 are rotatably mounted with a moving plate 24, and the upper end of the moving plate 24 is fixedly connected with a moving block 19, and the driving mechanism includes two threaded rods 25, which are rotatably mounted in the auxiliary rod 8, and the moving block 19 is inserted in the auxiliary rod 8 and slidably arranged in the auxiliary rod 8, and the two threaded rods 25 thread through the moving block 19. When the threaded rod 25 in the driving mechanism rotates, the moving block 19 is threadedly sleeved on the threaded rod 25, and the moving block 19 and the connected moving plate 24 can move with the rotation of the threaded rod 25.

[0021] A motor 26 is fixedly mounted on one end of the auxiliary rod 8, and a driving end of the motor 26 is fixedly connected to one of the threaded rods 25. A convex shaft 27 is fixedly connected to one end of the two threaded rods 25 away from the motor 26, and a traction shaft 28 is connected between one end of the two convex shafts 27 away from the threaded rods 25. When one of the threaded rods 25 rotates, the convex shaft 27 is driven to deflect, and the two convex shafts 27 are connected by the traction shaft 28. When one convex shaft 27 moves through the traction shaft 28 to drive the other convex shaft 27 to move, the two threaded rods 25 can rotate synchronously, and then with the rotation of the two threaded rods 25, the movement effect of the reel 7 can be achieved.

[0022] The movable frame 4 is provided with two rows of front and rear engaging grooves in cooperation with the two blackboards 2, and the engaging grooves include slots 13 and tooth slots 14. The first limiting mechanism 10 includes a gear 12 rotatably mounted on the side of the blackboard 2, and two plug shafts 16 are symmetrically arranged on the surface of the gear 12. The gear 12 is engaged and engaged with the tooth slots 14, and the two plug shafts 16 are engaged in the slots 13. During use, the teacher can directly move the blackboard 2. During the movement, the gear 12 will rotate adaptively, and the gear 12 will engage along the tooth slots 14. When the position of the blackboard 2 needs to be fixed, the two plug shafts 16 on the gear 12 are inserted into the corresponding slots 13, so that the position of the gear 12 can be fixed, thereby fixing the position of the blackboard 2.

[0023] A slide groove is provided on the plug shaft 16, a rotating shaft (not shown) is provided on the blackboard 2, the gear 12 is rotatably sleeved on the rotating shaft, a slider (not shown) corresponding to the slide groove is fixedly provided at the end of the rotating shaft, the two sliders are fixedly connected with the electromagnet 15, and the plug shaft 16 is fixedly connected with the magnetic block 17. When the electromagnet 15 is energized, the electromagnet 15 after energization has the effect of magnetic attraction and magnetic repulsion on the magnetic block 17. When the position of the gear 12 needs to be fixed, the electromagnet 15 magnetically repels the magnetic block 17, thereby driving the plug shaft 16 to move and insert it into the slot 13, and then the upper and lower positions of the gear 12 remain stable.

[0024] A telescopic shaft 18 is arranged in the chute. The telescopic shaft 18 is installed in the chute, and under the elastic force of the telescopic shaft 18, the plug shaft 16 can be clamped in the slot 13, and when the frame 5 needs to be moved up and down, the electromagnet 15 is energized to attract the magnetic block 17, and the plug shaft 16 is pulled out from the slot 13.

[0025] The second limiting mechanism 9 includes a roller 29 rotatably mounted on the side of the blackboard 2, a plurality of slots 20 are provided on the surface of the roller 29, a clamping mechanism is provided between two rollers 29, and the clamping mechanism is used to fix the angle of the roller 29. The clamping mechanism is clamped on the slot 20, so as to limit the angle of the roller 29, and the roller 29 with the limited angle is attached to the surface of the middle plate 3. The plurality of rollers 29 are attached to the middle plate 3, and the position of the blackboard 2 is kept stable under the action of friction.

[0026] The clamping mechanism includes a mounting block 22 and a clamping shaft 21 slidably mounted at both ends of the mounting block 22. One end of the clamping shaft 21 away from the mounting block 22 is clamped with the clamping slot 20. The mounting block 22 is fixedly connected to the side of the blackboard 2. An energized spring 23 is connected between the two clamping shafts 21. When the blackboard 2 needs to move up and down, the energized spring 23 is energized and contracted, and the clamping shaft 21 moves to disengage from the clamping slot 20, so that the roller 29 can move freely. When the blackboard 2 needs to be kept stable, the energized spring 23 is de-energized and pushes the two clamping shafts 21 away from each other under the action of elastic force, and the clamping shaft 21 is clamped and kept fixed by the clamping shaft 21 and the roller 29.

[0027] A mounting plate 11 is disposed on the back side of the middle plate 3 , and a plurality of mounting holes are formed on the mounting plate 11 .

[0028] When using this device, teachers can write directly on the blackboard 2. There are four blackboards 2 in the left and right space. The upper and lower blackboards 2 can be moved to change their positions, and the up and down movements will not interfere with each other. Therefore, users can completely move up and down according to their needs and change their positions to facilitate blackboard writing and teaching. At the same time, a projector can be used to project slides or other electronic teaching courseware on the screen 1.

[0029] The blackboard 2 is frequently used in mathematics teaching. In order to flexibly display the blackboard content, the position of the screen 1 can be changed, wherein the screen 1 can be automatically folded up and lowered. Its working principle is the existing technology and is not explained in detail here. The movement of the screen 1 adopts an electric control method. The electric control method also facilitates the projector to adaptively change its projection angle, ensuring that the projector can effectively project on the screen 1.

[0030] The motor 26 at one end of the auxiliary rod 8 is started to realize the rotation effect of one of the threaded rods 25. As the threaded rod 25 rotates, its end is connected to the traction shaft 28 through the convex shaft 27. The traction shaft 28 pulls the other threaded rod 25 to rotate synchronously, thereby making the two threaded rods 25 rotate synchronously. As the threaded rod 25 rotates, the moving block 19 can move in the auxiliary rod 8. As the moving block 19 moves, the moving plate 24 and the scroll 7 can be driven to move, thereby changing the position of the curtain 1.

[0031] When the user needs to change the upper and lower positions of the blackboard 2, a button is provided at the lower edge of each blackboard 2. The button controls the electromagnet 15 and the power spring 23 to be energized. When the electromagnet 15 is energized, it has magnetism to attract the magnetic block 17. Under the attraction, the plug shaft 16 moves and disengages from the slot 13, and the first limiting mechanism 10 disengages from the movable frame 4, so that the side of the blackboard 2 can move relatively freely.

[0032] When the power spring 23 is energized, it contracts so that the two clamping shafts 21 approach each other, and the clamping shaft 21 is disengaged from the clamped roller 29, so that the roller 29 can roll freely along the surface of the middle plate 3, so that the blackboard 2 can move up and down freely. When the position of the blackboard 2 is fixed, the power spring 23 is de-energized to extend the clamping shaft 21 and clamp it with the clamping slot 20, and the roller 29 cannot rotate, the electromagnet 15 is de-energized, and the telescopic shaft 18 extends to insert the plug shaft 16 into the slot 13, thereby limiting the height position of the gear 12, thereby fixing the position of the blackboard 2.

[0033] The blackboard 2 in the device can move up and down freely and can remain stable at any position, which is convenient for teachers to compare blackboards. At the same time, the position of the screen 1 can also be changed, and the automated change method is conducive to the alignment of the projector.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
