Adjustable English teaching aid and use method

Abstract

The invention discloses an adjustable English teaching aid and a use method. The adjustable English teaching aid comprises a teaching aid main body, a lifting adjusting assembly is fixed to the exterior of the plate surface of one side of the teaching aid main body, a limiting assembly is fixed to the interior of one side of the teaching aid main body, and a dust collecting assembly is fixed to the exterior of the bottom end of the teaching aid main body; and the lifting adjusting assembly comprises sliding blocks symmetrically welded and fixed to the plate surface of one side of the teaching aid main body, a rotating groove is formed in one side of each sliding block, a gear is installed in one side of each rotating groove, and a first motor is installed in one side of each rotating groove in an embedded mode. A first motor in the rotating groove is started to enable a gear to rotate, then under the meshing effect of a rack, a sliding block on the teaching aid main body ascends and descends along a first sliding groove in a first connecting plate, the teaching aid can be ascended and descended, a blackboard can be adjusted to a proper height, all the blackboards can be used for writing, convenience is provided for the teacher to write, and the use effect of the teaching aid is improved.

Description

technical field [0001] The invention belongs to the technical field of English education equipment, and specifically relates to an adjustable English teaching aid and a using method.

Problems solved by technology

[0003] However, when the existing teaching aids are taught by the teacher, because the teaching aids are fixed, the teaching aids cannot be raised and lowered. Due to the different elevations of the teacher, part of the blackboard cannot be written, which reduces the use effect of the teaching aids. There is no way to limit the position, which leads to the continuous use of the motor, which increases the loss of power and the cost of use, and the dust floating in the air cannot be collected, so that the dust will be inhaled by the teacher and reduce the health of the teacher
