Problems solved by technology

[0003] In the early stage of primary school Chinese teaching, teachers often need to help primary school students understand and standardize Chinese characters through Chinese blackboard writing. When teaching blackboard writing, they often need to draw matts on the blackboard. The drawing process requires tools such as a ruler, and only a few matts can be drawn at a time. font grid, and the drawing speed is slow, wasting teaching time

Embodiment 1

[0021] see Figure 1~3 , a display board for primary school Chinese teaching that is convenient for Chinese characters on the blackboard, comprising a base 1, a display board 4 is arranged above the base 1; hollow rods 2 are fixedly connected to the left and right sides of the top of the base 1, and the bottom of the display board 4 The left and right sides are fixedly connected with guide rods 3 that cooperate with the hollow rod 2, and the guide rod 3 extends into the hollow rod 2 and is slidably connected with the hollow rod 2, so that the display board 4 can only move up and down but cannot rotate; The center of the bottom of the display board 4 is fixedly connected with a lifting cylinder 5, and the inner wall of the lifting cylinder 5 is provided with threads; the center of the top of the base 1 is rotatably connected with a first screw 6 that cooperates with the lifting cylinder 5, and the first screw 6 extends into the lifting cylinder 5 and threadedly connected with t...

Embodiment 2

[0024] see Figure 4 , on the basis of Embodiment 1, the four corners of the bottom of the base 1 are respectively fixedly connected with the legs 20, and the legs 20 are cylindrical structures, and the four corners of the base 1 are respectively threaded with the second screw 21, and the bottom of the second screw 21 is Extending through the base 1 to the inside of the leg 20, the bottom end of the second screw 21 is fixedly connected with a universal wheel 23, and the top end of the second screw 21 is fixedly connected with a second handle 22, and turning the second handle 22 drives the first Two screw rods 21 can be rotated to control the universal wheel 23 to stretch out of the legs 20 or to retract in the legs 20. When the mobile device is needed, the universal wheel 23 is controlled to stretch out of the legs 20, which is convenient and labor-saving to move; The universal wheel 23 retracts into the support foot 20, and is supported by the support foot 20, which is more s...

Abstract

The invention relates to the technical field of Chinese teaching tools, and discloses a display board for Chinese teaching in primary school convenient for Chinese character blackboard-writing. The display board comprises a base; a display board is arranged above the base; first slide rails are arranged at the top and the bottom of a front panel of the display board in parallel; the first slide rails are slidingly connected with first slide blocks; second slide rails are fixedly connected between the upper and lower first slide blocks, and are slidingly connected with second slide blocks; theleft ends of the second slide blocks are hinged with rotating blocks through spring hinges; the spring hinges provide force towards the display board to the rotating blocks; chalk ports are formed inthe rotating blocks; the rotating blocks are in threaded connection with fastening bolts; and the fastening bolts extend into the chalk ports. Chalks can be fixed through arrangement of the rotating blocks; transverse straight lines can be drawn through left-right movement of the second slide rails; vertical straight lines can be drawn through up-down movement of the second slide blocks; and mattscan be drawn through combination of the transverse and vertical straight lines to achieve convenience and speediness.
