CN202319514U - Blackboard for Chinese teaching - Google Patents

Abstract

The utility model discloses a blackboard for Chinese teaching. The blackboard comprises a board body and a board frame fixed around the board body. A plurality of laser lights are arranged on the left or right side of the board frame at an equal interval from top to bottom. A plurality of laser lights are also arranged on the upper or lower side of the board frame at an equal interval from left to right. The interval between the laser lights arranged from top to bottom is equal to that of the laser lights arranged from left to right. A switch button for controlling the turning-on/turning-off of the laser lights is also arranged on the board frame. The utility model has the advantages that: (1) the blackboard has a simple structure; and (2) the laser lights arranged from top to bottom are vertical to the laser lights arranged from left to right, and the interval of the laser lights arranged from top to bottom is equal to that of the laser lights arranged from left to right, so that the laser lights emit light rays when the switch button is turned on to form a plurality of neatly arranged matts for a teacher to write Chinese characters, and the drawing of the matts is avoided; and therefore, the blackboard alleviates the workload of the teacher, and saves teaching time compared with the conventional blackboard.

Description

A kind of language teaching is used blackboard

Technical field

The utility model relates to a kind of mathematical education apparatus, particularly a kind of plane coordinates chi.

Background technology

At present, in the language teaching process, especially in the primary grades language teaching process; In order to give the Chinese character that writes out standard; Demonstration is learnt to students, and the teacher can draw a large amount of matts usually on blackboard, so that in matts, write; But it is draw a large amount of instructional blocks of times that matts can take the teacher, thereby very inconvenient.

Summary of the invention

The problem that the utility model will solve is: the language teaching that provides a kind of light simple in structure, that utilize laser lamp to form matts is used blackboard.

In order to solve the problems of the technologies described above; The language teaching of the utility model is used blackboard; Comprise plate body and be fixed on plate body sheet frame all around; Be provided with the laser lamp that several spacings equate on the sheet frame on said left side or right side from top to bottom; Right also be provided with the laser lamp that several spacings equate from a left side on the sheet frame of said upside or downside, the spacing of said laser lamp of arranging from top to bottom with from a left side and the spacing of right laser lamp of arranging equates, also be provided with a shift knob of controlling the laser lamp folding on the said sheet frame.

The beneficial effect that the utility model is obtained is: (1) is simple in structure; (2) starting switch button, then laser lamp emits beam since the laser lamp of arranging from top to bottom with from a left side and the laser lamp of arranging in the right side is vertical each other; And spacing equates, forms the matts that several are neatly arranged, so that teacher's writing Chinese characters is used; Compare with existing blackboard; Owing to need not draw matts, alleviated teacher's work load, practiced thrift hours of instruction.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Among the figure: 1, sheet frame, 2, laser lamp, 3, plate body, 4, shift knob.

The specific embodiment

As shown in Figure 1; The language teaching of the utility model is used blackboard; Comprise plate body 3 and the sheet frame 1 that is fixed on around the plate body 3, be provided with the laser lamp 2 that several spacings equate on the sheet frame 1 in said left side from top to bottom, rightly also be provided with the laser lamp 2 that several spacings equate from a left side on the sheet frame 1 of said upside; The spacing of the said laser lamp of arranging from top to bottom 2 with from a left side and the spacing of right laser lamp 2 of arranging equates, also be provided with a shift knob 4 of controlling laser lamp 2 foldings on the said sheet frame 1.

The language teaching of the utility model is used blackboard, in the time of concrete the drafting, opens shift knob 4; Then laser lamp 2 emits beam and since the laser lamp 2 of arranging from top to bottom with from a left side and right laser lamp of arranging 2 is vertical each other, and spacing is equal; Form the matts that several are neatly arranged, so that teacher's writing Chinese characters usefulness is compared with existing blackboard; Owing to need not draw matts, alleviated teacher's work load, practiced thrift hours of instruction.

The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of under the enlightenment of the utility model, making, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the utility model.

Claims (1)

1. a language teaching is used blackboard; Comprise plate body (3) and be fixed on plate body (3) sheet frame (1) all around; It is characterized in that: be provided with the laser lamp (2) that several spacings equate on the sheet frame on said left side or right side (1) from top to bottom; The sheet frame of said upside or downside (1) is gone up from a left side and rightly also is provided with the laser lamp (2) that several spacings equate; The spacing of said laser lamp of arranging from top to bottom (2) with from a left side and the spacing of right laser lamp (2) of arranging equates, also be provided with a shift knob (4) of controlling laser lamp (2) folding on the said sheet frame (1).
