Embodiment Construction

[0015] like figure 1 As shown, it is a front view of the teaching ruler 10 of a preferred embodiment of the present invention. The teaching ruler includes: a triangular plate-shaped ruler body 100 , a suction block 200 embedded in the ruler body 100 , a handle 300 fixed on the ruler body 100 and a protective layer 400 .

[0016] The handle 300 of this embodiment is in the shape of a cuboid.

[0017] There are three suction blocks 200, which are embedded in three corner regions of the ruler body 100 respectively. The suction block 200 can adsorb the teaching ruler 10 to the blackboard. In this embodiment, a magnet is used to adsorb the teaching ruler 10 on the magnetic blackboard.

[0018] Please also see figure 2 , which is figure 1 Right side view of teaching ruler 10 shown. The handle 300 is fixedly connected to one surface of the ruler body 100, and the protective layer 400 is attached to the other board surface of the ruler body 100, that is, the handle 300 is fixedl...

Abstract

A teaching ruler comprises a plate-shaped ruler body, three suction blocks and a protection layer. The suction blocks are embedded in the ruler body. The protection layer is attached onto one surface of the ruler body. In one embodiment, the teaching ruler further comprises a handle fixedly connected on the ruler body and the surface of the protection layer backing onto the surface where the protection layer is located. The handle is of a cube structure. The ruler body is triangular, the three suction blocks are embedded in three angle areas of the ruler body respectively, and the suction blocks are magnets. In use, the protection layer on the teaching ruler faces a blackboard, the teaching ruler is adsorbed on the blackboard under the adsorption force of the suction blocks, and inclining of the teaching ruler can be avoided in the use process. The teaching ruler can be conveniently moved by means of the handle, and the protection layer can reduce damage to the blackboard caused by moving of the teaching ruler simultaneously.

Description

technical field [0001] The invention relates to a teaching aid, in particular to a teaching ruler. Background technique [0002] Teaching ruler is an indispensable auxiliary tool in teaching. Teachers often draw pictures to help students understand problems during lectures. An efficient teaching ruler is not only convenient for teachers to use, but also saves time in teaching. [0003] The teaching ruler currently used in teaching is easy to tilt when drawing, which brings great inconvenience to the teacher, and the teaching ruler will also damage the blackboard during the movement process. Contents of the invention [0004] Based on this, it is necessary to provide a teaching ruler that is not easy to tilt and protect the blackboard when drawing. [0005] A teaching ruler, comprising: a plate-shaped ruler body, a suction block and a protective layer, [0006] The suction block is embedded in the ruler body; [0007] The protective layer is attached to one surface of t...
