Abstract

The invention relates to the field of teaching aids, and discloses a blackboard. The blackboard comprises a first blackboard body (1), a second blackboard body (2), a transmission structure (3) and adriver (4), wherein the second blackboard body (2) and the first blackboard body (1) are arranged opposite to each other, the transmission structure (3) is used for driving the first blackboard body (1) and the second blackboard body (2) to move oppositely, and the driver (4) is used for driving the transmission structure (3). According to the blackboard, the opposite first blackboard body (1) andthe second blackboard body (2) are arranged, and the first blackboard body (1) and the second blackboard body (2) are driven to move oppositely by driving the transmission structure through the driver, so that the manual push and pull of teachers are replaced, and the teaching efficiency of the teachers is improved advantageously.

Description

technical field [0001] The invention relates to the field of teaching appliances, in particular to a blackboard. Background technique [0002] The blackboard does not specifically refer to the black board. In the traditional sense, it is a plane that can be repeatedly written with chalk. The board is hard and is mostly used for teaching. Blackboards usually have two structural forms: fixed blackboard and push-pull blackboard. The existing push-pull blackboard usually relies on the teacher to manually push away the full blackboard, and then pull the blank blackboard over for the next step of writing, which is cumbersome to use and affects the teaching efficiency of the teacher. Contents of the invention [0003] The object of the present invention is to overcome the problem that the push-pull blackboard in the prior art needs to be manually pushed and pulled by the teacher, and provides a blackboard. It is used to drive the first blackboard body and the second blackboard ...
