Description

Technical Field

[0001] The utility model relates to the technical field of teaching appliances, in particular to a multifunctional chalk box. Background Art

[0002] The main component of chalk is calcium sulfate, a white precipitate that is not easy to decompose. The particles are larger than dust and are prone to breakage during the handling process and friction caused by storage equipment, which produces more chalk dust. Over time, the accumulated chalk dust will be brought up during the process of taking the chalk, thus affecting the classroom environment. This requires the use of a multifunctional chalk box.

[0003] Patent document CN214138057U discloses a multifunctional chalk box, "including: a box body, a first pen holder slot, a second pen holder slot and a chalk slot are provided downwardly on the top surface of the box body, the first pen holder slot, the second pen holder slot and the chalk slot are all blind slots, the deepest parts of the first pen holder slot and the second pen holder slot are provided to the top of the bottom surface of the box body, and two spare chalk chambers are provided on the side of the box body below the chalk slot, and a chalk drawer is provided in each of the spare chalk chambers. The utility model has a reasonable design and is easy to operate, effectively improves the service life of the chalk box and the efficiency of chalk retrieval during teaching, and provides a centralized storage space for teachers' teaching tools."

[0004] The above-mentioned equipment is gently raised through the upper bottom surface. When the drawer is opened and closed with chalk normally, the chalk will not roll out due to gravity, which effectively improves the service life of the chalk box and the efficiency of chalk retrieval during teaching, and provides centralized storage for teachers' teaching tools. Due to the inevitable collision between the chalk and the equipment during the process of storing and taking chalk, the surface of the chalk will be worn and broken, and the chalk dust will fall into the equipment. This will result in the chalk in the equipment being brought up during the subsequent process of taking and opening the equipment, thereby affecting the environment around the equipment, and this requires staff to improve their equipment.
