Description

Technical Field

[0001] The present application relates to the technical field of teaching tools, in particular to a self-erasing environmentally friendly blackboard. Background Art

[0002] Blackboard, as a commonly used teaching tool, is widely used in schools because it can be written on repeatedly. It is one of the indispensable teaching tools in schools. Existing environmentally friendly blackboards are mostly locked to the wall with through-wall screws, and are driven by internal multiple motors and a relatively complex transmission mechanism.

[0003] Existing self-erasing, eco-friendly blackboard erasers are often contaminated with chalk dust during use, which can affect their effectiveness and blur the writing on the blackboard. Furthermore, chalk dust can spill into the classroom, impacting student health and the learning environment. Furthermore, chalk dust accumulated at the bottom of the blackboard is difficult to clean, increasing the time it takes for teachers and students to clean the blackboard. Therefore, a self-erasing, eco-friendly blackboard has been proposed to address these issues. Summary of the Invention

[0004] In this embodiment, a self-erasing environmentally friendly blackboard is provided to solve the problem that the self-erasing environmentally friendly blackboard in the prior art will be contaminated with a large amount of chalk dust during use, which may affect the erasing effect of the blackboard eraser and make the writing on the blackboard blurred. At the same time, the chalk dust may be scattered in the classroom, affecting the health of students and the learning environment; and the chalk dust accumulated at the bottom of the blackboard is difficult to clean, which increases the time for teachers and students to clean the blackboard.

[0005] According to one aspect of the present application, a self-erasing environmentally friendly blackboard is provided, including a mounting plate and a mounting frame, a scraping assembly is provided on one side of the mounting plate, and the scraping assembly includes a slide rod, a scraper and a slider, two movable grooves are opened on one side of the mounting plate, and the inner cavity of the two movable grooves is opened with two slide grooves, the inner cavity of the two slide grooves is fixedly installed with a slide rod, one side of the two slide rods is slidably connected to the slider, and one side of the two sliders is fixedly installed to the same scraper.

[0006] Furthermore, a plurality of the slide rods are sleeved with a spring, and both ends of the spring are fixedly connected to the slide groove and the slider respectively.

[0007] Furthermore, a mounting bracket is fixedly mounted on one side of the mounting plate, a threaded rod is rotatably connected to the interior of the mounting bracket via a bearing, a motor is fixedly mounted on one side of the mounting bracket, and an output shaft of the motor extends to the interior of the mounting bracket and is fixedly connected to the threaded rod.

[0008] Furthermore, a movable plate is threaded on the threaded rod, and a blackboard eraser is fixedly connected to one side of the movable plate.

[0009] Furthermore, a blackboard is provided inside the mounting plate.

[0010] Furthermore, a guide rod is fixedly installed inside the mounting frame, and the guide rod is slidably connected to the movable plate.

[0011] Furthermore, two ash outlets are provided at the bottom end of the mounting frame, an ash outlet pipe is fixedly installed at the bottom end of the mounting frame at the position of the ash outlet, and a collection box is threadedly connected to the ash outlet pipe.

[0012] Furthermore, a connecting plate is fixedly installed on the bottom end of the movable plate, and a cleaning brush is fixedly connected to the bottom end of the connecting plate.

[0013] Through the above-mentioned embodiment of the present application, by setting a scraping component and starting the motor, when the movable plate moves to both sides of the blackboard, the scraper will scrape the residual chalk dust on the blackboard eraser, so the chalk dust on the blackboard eraser can be cleaned in time, and the cleanliness and erasing performance of the blackboard eraser can be maintained, which not only ensures that the blackboard writing is clear, but also avoids the scattering of chalk dust; by starting the motor, the connecting plate drives the cleaning brush to clean the chalk dust that falls to the bottom of the mounting frame, and the cleaning brush pushes the chalk dust to the two ash outlets, and the chalk dust falls into the inside of the collection box along the ash outlet pipe, reducing the time for teachers and students to manually clean the blackboard, thereby improving teaching efficiency, and can also clean the chalk dust at the bottom and collect it into the collection box, thereby reducing the health hazards of chalk dust to teachers and students.
