Detailed implementation manners

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-7 As shown, the present invention provides the following technical solutions: An intelligent mathematics teaching auxiliary device includes a driving member 1 fixed to the top and bottom of the blackboard. The driving member 1 includes a guide rail 14. A side groove 15 is recessed on one side of the guide rail 14. A lead screw 16 is rotatably connected inside the side groove 15 along its own length direction. Movable moving blocks 17 are sleeved on both lead screws 16. One side of each of the two moving blocks 17 is fixedly connected with a support plate 18. Jacks 19 are formed in an open manner on both support plates 18. A detachable moving member 2 is installed between the two jacks 19. A cleaning plane for scraping the blackboard is formed on the side of the moving member 2 facing the blackboard.

[0020] Through the above technical solutions, before the device is put into use, the two guide rails 14 are respectively fixed above and below the blackboard. After the guide rails 14 are fixed, the moving member 2 is installed between the two support plates 18, so that the moving member 2 is fixed in the jacks 19 on the two support plates 18. After the moving member 2 is fixed, the lead screw 16 rotates in the side groove 15 inside the guide rail 14, thereby driving the moving block 17 to move along the side groove 15. When the moving block 17 moves, it will drive the support plate 18 to move together, so that the support plate 18 drives the moving member 2 to move, and then the cleaning plane on one side of the moving member 2 scrapes the blackboard, thereby cleaning the blackboard, making it convenient for teaching staff to write on the blackboard without wasting their own time cleaning the blackboard.

[0021] Specifically, in one implementation manner, regarding the above moving member 2: As Figures 1-4 and Figures 6-7As shown, the moving member 2 includes a moving plate 21. Plug rods 27 are fixedly connected to both the top and bottom of the moving plate 21. The plug rods 27 are matched with the jacks 19. A through slot 28 is formed in the moving plate 21. A detachable clamping plate 29 is installed inside the slot 28. One side of the clamping plate 29 is fixedly connected to a scraping plate 210.

[0022] In this embodiment, before cleaning the blackboard, the clamping plate 29 is engaged with the slot 28 on the moving plate 21, so that the scraping plate 210 is fixed to one side of the moving plate 21. After the clamping plate 29 and the scraping plate 210 are installed, the screw rod 16 rotates in the side slot 15 inside the guide rail 14, thereby driving the moving block 17 to move along the side slot 15. When the moving block 17 moves, it will drive the support plate 18 to move together, so that the support plate 18 drives the moving plate 21 to move, and then the moving plate 21 and the scraping plate 210 move together, so that the scraping plate 210 scrapes the blackboard, thereby cleaning the blackboard.

[0023] To facilitate the storage of the dust generated when cleaning the blackboard, as Figure 6 shown, the side of the scraping plate 210 facing the blackboard is recessed to form a cavity for storing dust. When the scraping plate 210 scrapes the blackboard, the cavity stores the dust on the blackboard.

[0024] Moreover, in the present invention, to facilitate the collection of dust, as Figures 6-7 shown, a dust storage box 22 is fixedly connected to the side of the moving plate 21 away from the scraping plate 210. A negative pressure pump 25 is fixedly connected to one side of the dust storage box 22, and a connecting pipe 211 is fixedly connected to the other side. The free end of the connecting pipe 211 communicates with the cavity inside the scraping plate 210. One side of the dust storage box 22 is open and recessed to form a dust storage cavity 23. The dust storage cavity 23 is located between the connecting pipe 211 and the negative pressure pump 25. And a baffle 24 for covering the dust storage cavity 23 is rotatably connected to one side of the dust storage box 22.

[0025] In this embodiment, when the scraping plate 210 scrapes the blackboard to generate dust, the negative pressure pump 25 works, so that negative pressure is generated inside the dust storage box 22 to generate suction, thereby making the connecting pipe 211 generate suction. The dust inside the cavity is sucked through the connecting pipe 211, so that the dust is inhaled into the dust storage cavity 23, preventing the dust from spreading around. When the user needs to clean the dust, the user only needs to pull the baffle 24 to open the baffle 24, so that the dust storage cavity 23 is exposed, and the user can take out the dust inside the dust storage cavity 23 for cleaning, making it convenient for the user to centrally process the dust and improving the processing efficiency of the dust.

[0026] After the scraping plate 210 is connected to the moving plate 21, to make the scraping plate 210 more stable during operation, as Figures 6-7 shown, a limit screw rod 26 is screwed on the side of the moving plate 21 away from the scraping plate 210. The free end of the limit screw rod 26 extends into the slot 28 and abuts against the scraping plate 210.

[0027] In this embodiment, after the clamping plate 29 is engaged with the clamping groove 28, one end of the limit screw 26 is screwed and connected to the moving plate 21 until one end of the limit screw 26 extends into the clamping groove 28 and abuts against the clamping plate 29, so that the clamping plate 29 and the scraping plate 210 are more firmly installed after installation. When the clamping plate 29 and the scraping plate 210 need to be disassembled, only the limit screw 26 needs to be unscrewed, and then the clamping plate 29 and the scraping plate 210 can be replaced.

[0028] When the device sucks dust, in order to prevent the dust from being sucked into the negative pressure pump 25, a filter screen is installed at the intake end of the negative pressure pump 25, and the filter screen is inside the dust storage cavity 23.

[0029] Regarding how the lead screw 16 rotates, as Figures 1-5 shown, a motor 11 is fixedly connected to one side of the guide rail 14, and the output end of the motor 11 is connected to the lead screw 16.

[0030] In this embodiment, when the lead screw 16 needs to be driven to rotate, the motor 11 works, and then the motor 11 drives the lead screw 16 to rotate, and then the moving block 17 moves.

[0031] In addition, in the present invention, regarding how the guide rail 14 is fixed, as Figures 1-5 shown, side plates 12 are fixedly connected to both the top and bottom of the guide rail 14, and fixing screws 13 are screwed on the side plates 12.

[0032] In this embodiment, when the guide rail 14 needs to be fixed, the guide rail 14 is placed above and below the blackboard, and then the fixing screw 13 is rotated through the side plate 12 so that the fixing screw 13 enters the wall, thereby fixing the guide rail 14.

[0033] When the moving block 17 moves, in order to make the moving block 17 more stable, as Figures 1-5 shown, protrusions are formed by outward protrusion on both the top and bottom of the moving block 17, and guide grooves matching the protrusions are formed by inward depression at both the top and bottom inside the side groove 15, and the guide grooves are distributed along the length direction of the side groove 15.

[0034] In this embodiment, when the moving block 17 moves, through the cooperation of the protrusions and the grooves, the moving block 17 moves more smoothly.

[0035] In addition, in the present invention, in order to make the limit screw 26 abut against the clamping plate 29 more firmly, as Figure 7 shown, a limit groove 212 is formed by inward depression on the side of the clamping plate 29 facing the limit screw 26, and the limit groove 212 matches the limit screw 26.

[0036] In this embodiment, after the clamping plate 29 is engaged with the clamping groove 28, the limiting screw rod 26 is screwed and connected with the moving plate 21, so that one end of the limiting screw rod 26 abuts against the clamping plate 29, making the clamping plate 29 more firmly fixed after being fixed.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
