Description

A kind of English teaching blackboard

Technical field

The utility model relates to educational aid, is specifically related to a kind of English teaching blackboard.

Background technology

English, belong to the West Germanic Dialect under Germanic branc in Indo-European family of languages, be by migrating ancient times to the big belly lattice Shandong of The British Isles from Northern Europe five state and the Scandinavian Peninsula, the said Language Evolution of Germanic people of Anglo-Saxon and Zhu Te clan, and propagate into all over the world by the colonial activities of Britain.Owing to once contacting with multiple native language in history, its vocabulary became polynary from unitary, and grammer becomes from " many flexions " " few flexion ", and voice also there occurs regular change.

Calculate according to using English as the number of mother tongue, English is the maximum official languages that use of country, and English is also second language the most widely in the world, Ye Shi European Union, one of official language of maximum international organization and British commonwealth of nations.But only have the mother tongue user of third place in the world, be less than standard Chinese and Spanish.Upper two century Britain and the U.S. make English become a kind of International Language in culture, economy, military affairs, politics and scientific leading position.Nowadays, many international occasions all make in English as communication media.English is also contact the closest language with computer, and most of programming language is all related with English, and along with the use of network, makes English use more universal.English is one of working language of the United Nations.

Writing of Chinese take matts as standard, writing of English is for standard with four line lattice, in process of English teaching, because four line lattice are drawn four line lattice and are very lost time, teacher again blackboard can not draw four line lattice, and the aid of existing picture four line lattice is also generally handheld tool, is not only not easy to carry, and drawn four line lattice are difficult to reach parallel standard, effectively solve the problem of drawing four line lattice on blackboard and effectively can improve the normalization that everybody writes.

Utility model content

Based on the technical problem that background technology exists, the utility model proposes a kind of English teaching blackboard, it is easy for removal and installation, four line lattice of the standard that draws that can be stable and carrying without the need to teacher.

A kind of English teaching blackboard that the utility model proposes, comprises blackboard main body, fixed mechanism and multiple setting-out mechanism;

Fixed mechanism comprises two cross bars, two vertical poles and setting-out bar, two cross bars lay respectively at upper end and the blackboard main body of blackboard main body, two vertical poles are positioned at the both sides of blackboard main body, and two cross bars are fixedly connected with by two vertical poles, and setting-out bar is removable to be arranged between two cross bars;

Setting-out mechanism is all removable to be arranged on setting-out bar, setting-out mechanism comprises the pen cap, the cap for brush, the first elastic component, top cover and multiple second elastic component, the cap for brush and the pen cap are fastened and connected, top cover is removable to be arranged in the pen cap and to be connected with the cap for brush by the first elastic component, and the second elastic component is installed in the side of the relative and cap for brush of the pen cap.

Preferably, setting-out bar is provided with scale.

Preferably, setting-out mechanism is provided with four, and setting-out mechanism also comprises buckle, and buckle to be arranged on the pen cap and to be fixedly connected with setting-out bar by screw.

Preferably, the first elastic component is spring.

Preferably, the second elastic component is at least provided with three, and the second elastic component comprises elastic sheet metal and roller, and elastic sheet metal first end is arranged on the pen cap, and roller is arranged on elastic sheet metal second end.

The utility model is convenient by installation or removal, top cover and the second elastic component can effectively prevent chalk from rocking in the pen cap, effective stability increased when using the setting-out of setting-out mechanism, the first elastic component can continuous driven forward chalk, through normal adjustment chalk position after avoiding chalk to wear and tear.
