Description

An English teaching marking device

technical field

The utility model belongs to the field of teaching appliances, in particular to an English teaching marking device.

Background technique

In English teaching, especially in the teaching of words and phonetic symbols, teachers need to draw four-line grids in English in order to write words and phonetic symbols more standardizedly. However, it is difficult to draw four parallel grids only relying on hand feeling and eyes Once the four-line grid drawing is not standardized, the letters and phonetic symbols written by the teacher will be deformed. This deformation is not only unsightly, but also confuses the students, who cannot understand the regular writing of words and phonetic symbols.

Utility model content

In order to solve the above-mentioned problems in the prior art, the utility model provides an English teaching marking device.

The technical scheme adopted in the utility model is:

An English teaching marking device is composed of two horizontal bars, two vertical bars and a moving marking structure. The two horizontal bars are fixed between the two longitudinal bars, and the two horizontal bars pass through the moving marking structure. line structure, and the movable marking structure can slide on two crossbars. The moving marking structure is composed of a sliding rod, a chalk fixing structure and a handle. The two crossing bars pass through the perforations on the sliding rod, and the chalk The structure is fixed on the sliding rod at equal intervals, and the handle is a U-shaped structure, and its two ends are respectively fixed on the two ends of the sliding rod.

As a further improvement of the utility model, the chalk fixing structure is composed of a fixing block, a push rod, a nut and a chalk sleeve, the fixing block bolt is fixed on the sliding rod, and the chalk sleeve passes through and is fixed on the As for the fixed block, the inside of the push rod is threadedly connected with the threaded rod matched with the nut, the tail of the threaded rod is located in the chalk sleeve, and the bottom of the chalk sleeve is provided with a fixing bolt.

As a further improvement of the utility model, two suction cups are arranged on the inner side of one of the longitudinal rods.

The beneficial effects of the utility model are: the English teaching marking device of the utility model is simple to operate and easy to use. You only need to put the device on the blackboard and pull the handle to draw four parallel lines on the blackboard, and The overall structure of the device is stable, and the chalk is also well fixed, which brings great convenience to the teacher's teaching and improves the teaching efficiency in the classroom.

detailed description

As shown in Figure 1, a kind of marking device for English teaching of the present utility model is made up of two horizontal bars 1, two vertical bars 2 and a moving marking structure 3, and the two horizontal bars 1 are fixed on two Between two vertical rods 2, the inner side of one of them is provided with two suction cups 13, which are used to fix the vertical rod 2 on the non-hand-held side on the blackboard, so that the structure is more stable when marking lines; two horizontal rods 1 Pass through the moving marking structure 3, and the moving marking structure 3 can slide on two crossbars 1; the moving marking structure 3 is composed of a sliding bar 4, a chalk fixing structure 5 and a handle 6 (as shown in Fig. 2 ), two crossbars 1 pass through the perforation 7 on the sliding rod 4, the number of chalk fixing structures 5 is four, and the four chalk fixing structures 5 are fixed on the sliding rod 4 at equal intervals; the handle 6 is a U-shaped structure, Its two ends are respectively fixed on the two ends of the sliding rod 4. When drawing a line, the user only needs to pull the handle 6 to drive the sliding rod 4 to move, and the sliding rod 4 drives the four chalk fixing structures 5 to draw on the blackboard. Out of four lines; the chalk fixing structure 5 is composed of a fixing block 8, a push rod 9, a nut 10 and a chalk sleeve 11 (as shown in Figure 3), and the fixing block 8 is bolted on the sliding rod 4 , the chalk casing 11 passes through and is fixed on the fixed block 8, and the inside of the push rod 9 is threadedly connected with the threaded rod matched with the nut 10, and the tail of the threaded rod is located in the chalk casing 11, when the chalk is exposed to a shorter , the nut 10 can be turned, and the threaded rod matched with the nut 10 will push out the chalk; Chalk is fixed and in the chalk casing 11.

Before use, put the chalk into the four chalk fixing structures 5 for standby; when in use, the longitudinal rod 2 with the suction cup 13 can be fixed in an appropriate position by the suction cup 13, and then the user presses the other longitudinal rod with one hand 2. Pull the handle 6 with the other hand to draw a four-line grid.

The utility model is not limited to the above-mentioned best implementation mode, anyone can draw other various forms of products under the enlightenment of the utility model, but no matter make any changes on its shape or structure, all have the same features as the application Or similar technical schemes all fall within the protection scope of the present utility model.
