Multifunctional blackboard

Abstract

The invention discloses a multifunctional blackboard. The two ends of a sliding block are inserted into slideways in a penetrating manner, and the sliding block can move in the slideways according to a certain rail; an ash collection slot is reserved in the bottom of the inner cavity of a framework; an ash collection box is mounted at one end of the ash collection slot; a supporting device comprises supporting bases, supporting rods, telescopic rods and positioning pins; the supporting rods with hollow structures are fixedly mounted in the middles of the top ends of the supporting bases; the telescopic rods are inserted into the supporting rods in a penetrating manner; positioning pins for positioning the heights of the telescopic rods are mounted at the upper parts of the supporting rods; the top ends of the telescopic rods are fixedly connected with the bottom of the framework. According to the multifunctional blackboard, a blackboard eraser and a blackboard body are designed into an integrated structure, so that the quantity of teaching aids carried by a teacher is reduced; the multifunctional blackboard is further provided with the ash collection slot and the ash collection box structures which are used for collecting ash falling onto the blackboard surface, so that the ash is prevented from falling onto the ground. The multifunctional blackboard is provided with the supporting device capable of freely adjusting the height, so that the teaching requirement of the teacher can be met.

Description

Technical field [0001] The invention relates to the technical field of teaching appliances, in particular to a multifunctional blackboard. Background technique [0002] The blackboard is an indispensable teaching tool for teaching. During the use of the traditional blackboard, the dust scattered on the blackboard will fall on the ground and need to be manually cleaned. The traditional blackboard cannot be adjusted according to the teacher’s teaching requirements, and is not humane enough. In addition, the blackboard eraser is always carried when using the blackboard. The traditional blackboard eraser is small and will increase the workload of the teacher. For this reason, we propose a multifunctional blackboard to solve these problems. Summary of the invention [0003] The purpose of the present invention is to provide a multifunctional blackboard to solve the problems raised in the background art. [0004] In order to achieve the above object, the present invention provides the fo...
