Four-line grid quick drawing device in English teaching board

Abstract

The invention discloses a four-line grid quick drawing device in an English teaching board. The device comprises a frame board, wherein U-shaped handles are symmetrically and fixedly connected to theleft side and the right side of the frame board; a clamping strip board is slidably connected to an inner cavity of the frame board; a clamping groove is formed in the left side of the clamping stripboard; a bolt column is fixedly connected to the right side of the inner cavity of the clamping groove; a locking strip board is connected with the bolt column in a sleeving mode; a butterfly nut is screwed on the bolt column; hinge grooves are formed in the upper end and the lower end of the front side wall of the clamping strip board; guide rods are movably connected to the right sides of the inner cavities of the two groups of hinge grooves; prism stop pins are symmetrically inserted into the upper and lower sides of the clamping strip board; one ends, close to each other, of the two groupsof the prism stop pins extending into one sides, close to the bolt column, of the inner cavities of the hinge grooves; and four groups of chalk accommodating holes are formed in the upper end and thelower end of the front side wall at the joint of the clamping strip board and the locking strip boards at equal intervals. According to the device, the structure design is reasonable; and four-line grid can be quickly drawn conveniently to facilitate standardization of the writing of students, and both the learning efficiency of the students and the teaching quality of teachers are improved.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a four-line fast marking device on an English teaching board. Background technique [0002] As a language, English is more and more used by people. With the development of society, it is especially important for job seekers in the workplace to know a foreign language. English is a compulsory language in full-time teaching.

AI Technical Summary

Problems solved by technology

[0003] The spelling letters used in modern English are completely borrowed from 26 English letters. In the process of teaching English, it is necessary to write the English letters used. The basic four-line grid is used for writing teaching. In most cases, the teacher uses the method of manually drawing the four-line grid for teaching. Because the hand-drawn four-line grid is not standardized, students cannot write and use it in a standardized way, and the learning efficiency is low. The quality of teaching is poor. For this reason, we propose a four-line grid fast marking device in the English teaching board
