Abstract

The utility model relates to a loving-teacher type blackboard belonging to a field of teaching tool, which solves technical problem so as to provide convenience for writing, drawing, painting, and fastening wall map, thereby improving teaching quality of teachers, saving teaching time of teachers, and serving for teaching efficiently. The blackboard has the same shape as the general blackboard, except that the back of the ground glass (1) as the blackboard surface is adhered with a black-bottom stainless steel plate (2) with same size and squared paper graphic and then is matched with a chess-like permanent magnet (3) for application. The ground glass (1) is convenient for writing; the black-bottom squared paper graphic can provide the support for teaching, drawing and painting, and the teaching wall map is fixed by the suction between the magnet (3) and the stainless steel plate (2).

Description

Blackboard with coordinate steel sheet

Affiliated technical field

The utility model relates to the teaching aid field of teaching appliance, relates to Blackboard with coordinate steel sheet particularly.

Background technology

At present, known teaching is made by materials such as wooden, cement, frosted glass with blackboard.Though these blackboards have advantage simple in structure, but there are following two big shortcomings: the one, not as the grid and the length mark of manuscript paper, cause teacher's writing on the blackboard irregular, mapping, drawing etc. do not have support, have brought many troubles to teachers ' teaching; The 2nd, fixedly school wall map inconvenience, and fragile wall chart.

Summary of the invention

Be unfavorable in order to overcome existing blackboard that the teacher writes, maps, the shortcoming of drawing, wall chart, a kind of Blackboard with coordinate steel sheet is provided, it can not only be for teaching board, mapping, drawing etc. rely on, and can make teacher's fixing school wall map easily.

Solving the technical scheme that its technical problem adopts is: at the frosted glass of making the plate face (1) back side additional one with its onesize black matrix stainless steel substrates (2) that has the coordinate pattern, join alnico magnets (3) use of several chessman shapes again.The frosted glass (1) of making the plate face not only is convenient to the teacher and is write, and the black matrix graph paper pattern on the stainless steel substrates (2) that the people is seen tightly be attached to its back, this pattern teacher on hand can see, thereby by its writing on the blackboard, mapping, drawing etc., can improve the writing on the blackboard quality, can save instructional blocks of time again, play a multiplier role, but can't see this pattern in student at a distance, thereby can not influence student's visual quality; The character of utilizing stainless steel substrates (2) and alnico magnets (3) to inhale mutually fixes school wall map, and can use long-term effectively, has saved the thing of drawing pin commonly used, glue, adhesive tape, folder and so on, like this, not only easy to use, save time, and can guarantee that wall chart is not damaged.

The beneficial effects of the utility model are, can be for teacher's writing on the blackboard, mapping, drawing, fixedly wall chart etc. provides a lot of convenience.

Description of drawings

Below in conjunction with drawings and Examples utility model is further specified.

Fig. 1 is a structural front view of the present utility model.

Fig. 2 is a structure side view of the present utility model.

Fig. 3 is the side view that is used for fixing the alnico magnets of school wall map in the utility model.

1. frosted glass among the figure, 2. one side has the stainless steel substrates of black matrix graph paper pattern, the 3. alnico magnets of chessman shape.

The specific embodiment

In Fig. 1, the one side that has the graph paper pattern on the back side of frosted glass (1) and the stainless steel substrates (2) should closely be pasted mutually, and the slit must not be arranged, and teacher on hand can see through focussing glass face (1) see black matrix graph paper pattern.

In embodiment illustrated in fig. 2, stainless steel substrates (2) should be open and flat, and it is thin that the coordinate lines are wanted, and should adopt red or yellow.

Another embodiment shown in Figure 3 is the alnico magnets of chessman shape, and its surface is coated with the red lacquer of one deck or green lacquer is advisable, and is not only eye-catching but also attractive in appearance like this.

Claims

1, a kind of Blackboard with coordinate steel sheet that is used to impart knowledge to students, have for the plate face that uses, it is characterized in that: will make the back side of frosted glass (1) of plate face and the one side that has black matrix graph paper pattern of a stainless steel substrates onesize (2) and closely paste mutually, and utilize fixedly school wall map of character that magnet (3) and stainless steel substrates (2) inhale mutually with it.

2, Blackboard with coordinate steel sheet according to claim 1 is characterized in that: the coordinate recto must be close to the back of frosted glass.

3, Blackboard with coordinate steel sheet according to claim 1 is characterized in that: stainless steel substrates must be close to the back side of graph paper, and alnico magnets should adopt the chessman shape.
