CN2167856Y - High-efficient teaching stripe blackboard - Google Patents

Abstract

The utility model relates to a high-efficient teaching strip blackboard. A rotary trigonous strip is arranged in one side frame of the blackboard. Because the high-efficient teaching strip blackboard can be rotated flexibly, a teacher can write different training contents on the three surfaces of the blackboard before class begins; thus, when the teaching contents need to be shown in teaching process, the teaching contents can be shown quickly in front of students only by rotating the strip lightly. The writing capacity of the blackboard is large, and the utility model is especially suitable for the characteristic of fast rhythm in multilevel complex teaching in a primary school. In addition, the utility model which is made of plastic has the advantages of no blackboard paint, good tinctorial property of chalk, easy cleaning, no light reflection, wood saving, production process reduction and low cost.

Description

High-efficient teaching stripe blackboard

The utility model relates to a kind of writing blackboard, particularly a kind of efficient teaching bar shaped blackboard.

At present, in China's primary school and middle school teaching, main dependence oral account, chalk board are drilled this conventional teaching means of begging for.Because of the content of courses that blackboard shows limited, in order to make blackboard show the more content of courses to greatest extent, some blackboards that can rotate have appearred, as disclosed belt Rotary Blackboard among the Chinese patent CN2052355U, this blackboard drives the circulation of plate face by carrier chain and moves and blackboard surface is risen reach the purpose that increases the blackboard effective area, but this kind blackboard exists structure complicated and need the deficiency of certain floor space.

The purpose of this utility model is to provide a kind of and hangs on the wall three and show the various teaching content, show the fast efficient teaching bar shaped blackboard of the content of courses.

The purpose of this utility model realizes with following proposal: blackboard comprises the rotating batten that be arranged in parallel in frame, the frame.

Above-mentioned batten is that two ends are all established locating shaft and black three ribs on three planes are arranged.

Said fixing is established the boss equipped mutually with the batten locating shaft in the side frame inboard at frame two ends.

The utility model provides condition for the teacher selects the teaching of high efficiency means for use.The teacher can write the various teaching content on three faces, when showing the content of courses on class, only need rotate batten gently, and the content of courses just can appear at rapidly in face of the student, has improved efficiency of teaching and student's notice and learning interest.The utility model rotates flexibly, and a blackboard can be equivalent to three small blackboards, and the capacity of writing is particularly suitable for the fast characteristics of teaching rhythm in the multistage simultanous conducting of lesson of primary school greatly.The batten of this blackboard can adopt the high-quality regenerated plastics to make, and its quality is solid, durable, light, and without the erasing blackboard lacquer, the chalk coloring is good, easily wipes not reflective.Not only saved timber, reduced manufacture craft, and reduced production cost.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the utility model overall schematic;

Fig. 2 is the utility model batten front view;

Fig. 3 is the utility model batten side view;

Fig. 4 is the utility model side frame overall schematic;

Fig. 5 is that the utility model side frame B-B is to cutaway view;

Fig. 6 is that the utility model side frame A-A is to cutaway view.

As shown in Figure 1, the frame of blackboard (1) is gone up fixed handle (3), and frame (1) two ends of blackboard can be fixed or be inlaid in to two side frames (1a) by screw, and batten (2) is set in parallel on the side frame (1a).Batten (2) can optionally be provided with the 6-10 root.Side frame (1a) and frame (1) can adopt timber to make, and batten (2) can adopt plastic production.

As shown in Figure 2, locating shaft is all established at batten (2) two ends.

As shown in Figure 3, batten (2) is for there being three ribs on three planes.

As shown in Figure 4, side frame (1a) is established the boss equipped mutually with batten (2) locating shaft.

As shown in Figure 5, the framework cross section of side frame (1a) is a shaped as frame.

As shown in Figure 6, to establish the cross section at boss place be huge to side frame (1a).

Claims (4)

1, a kind of efficient teaching bar shaped blackboard comprises frame (1), it is characterized in that the rotating batten (2) that be arranged in parallel in the frame (1).

2, efficient teaching bar shaped blackboard as claimed in claim 1 is characterized in that batten (2) all establishes black three ribs that locating shaft has three planes for two ends.

3, efficient teaching bar shaped blackboard as claimed in claim 1 or 2, the boss equipped mutually with the batten locating shaft established in side frame (1a) inboard that it is characterized in that being fixed on frame (1) two ends.

4, efficient teaching bar shaped blackboard as claimed in claim 1 or 2 is characterized in that a side of frame (1) is fixed with handle (3).
