A primary education teaching aid device and its operation process

Abstract

The invention discloses a primary education teaching auxiliary device, and relates to the technical field of teaching equipment. The primary education teaching auxiliary device comprises a blackboardbody and a dust receiving box; sliding plates are arranged on the two sides of the blackboard body in a penetrating mode correspondingly, and the sides, extending to inner cavities of the sliding plates, of the blackboard body are slidably connected with one sides of the inner cavities of the sliding plates; the surface of the blackboard body is fixedly connected with a fixing box; and a tooth plate is fixedly connected between the top and the bottom of an inner cavity of the fixing box. According to the primary education teaching auxiliary device and an operating process thereof, dust on theblackboard body can be wiped well, the overall wiping speed is greatly increased, the labor intensity of a teacher is lowered while the time of the teacher is saved, and the blackboard body is wiped in an all-round mode; and the dust after the blackboard body is wiped can be collected well, the situation that the dust stays in a space during wiping is avoided, the harm of the dust to the teacher is relieved, and the overall height of the blackboard body can be adjusted.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to an auxiliary teaching device for primary school education and its operation process. Background technique [0002] Teaching equipment refers to teaching and scientific research units with a unit price of more than 800 yuan (inclusive) and used for teaching or scientific research.
