Description
Technical field
The utility model relates to educational aid, is specifically related to a kind of blackboard for education being convenient to picture four line lattice.
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, teacher again blackboard can not draw four line lattice, because four line lattice are drawn four line lattice and are very lost time, the aid of existing picture four line lattice is also generally handheld tool, not only be not easy to carry, and due to the length of chalker certain, therefore draw in four line lattice processes and unavoidably there will be broken string and the uneven situation of drawn four line lattice, the problem that four line lattice are drawn in effective solution on blackboard effectively can improve the normalization that everybody writes, therefore market is badly in need of a kind of device that effectively can solve upper picture four line lattice on blackboard.
Utility model content
The purpose of this utility model is the defect for above-mentioned prior art, provides a kind of blackboard for education being convenient to picture four line lattice, has and carry with without teacher, there is not the advantage of broken string situation when drawing four line lattice.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of blackboard for education being convenient to picture four line lattice, comprise blackboard main body and scriber, described scriber comprises roller, connecting rod and chalker, and described roller is provided with two, described connecting rod is connected between two described rollers, and described chalker is fixedly connected on described connecting rod; Described chalker comprises chalk sleeve and fixed mount, described fixed mount is fixedly connected on described chalk sleeve, described fixed mount is provided with buckling piece, described connecting rod is provided with the buckling groove suitable with described buckling piece, described chalk sleeve inside is provided with circular slab, and described circular slab is connected with described chalk sleeve by spring.
Preferably, described blackboard main body upper end and described blackboard main body lower end are provided with the groove suitable with described roller, ensure that roller prevents the utility model from dropping while movement in blackboard main body.
Preferably, described chalker is at least provided with four, ensures that the utility model is mobile in blackboard main body and once at least can draw four line lattice.
Preferably, described connecting rod is provided with scale, facilitates teacher to regulate the width between four line lattice accurately according to the custom of oneself.
Preferably, described fixed mount is also provided with pointer tip, when effectively improving picture four line lattice, the levels of precision of the spacing of four line lattice.
The beneficial effects of the utility model: the utility model structure is simple, easy to operate, teacher is not needed to carry, and the teacher not affecting other subject uses blackboard, the utility model can need according to the concrete of teacher the position regulating width and the four line lattice drawn between four line lattice, and the quantity drawing four line lattice can be regulated as required, and automatically supplement forward after these practical confidence chalk wearing and tearing, do not need teacher often to regulate the position of chalk, used up when chalk and can change easily yet.
