Detailed ways

As shown in Figure 1 and Figure 2, an easy-to-adjust Chinese language teaching display device is characterized in that: it includes a display board 1, a base, a top block 6, a push plate 10 and a fixed assembly;

The base is provided with a bracket, the push plate 10 is located above the base and is rotatably connected with the bracket, the push plate 10 can rotate in a vertical plane around the rotating shaft, and a spring 11 is connected between the push plate 10 and the base;

The base is provided with a vertical column 3, and the top block 6 is located above the push plate 10 and can be slidably installed on the column 3; Column 3 abuts;

The display board 1 is located above the top block 6 and is inclined on the upright column 3; the display board 1 is oscillatingly connected to the upright column 3, and abuts on the top block 6 under the action of its own weight; the push plate 10 rotates upward under the action of external force, through the The top rod 7 pushes the top block 6 to slide upward, and the top block 6 pushes the display board 1 to swing in the vertical plane around the swing axis;

Specifically, as shown in FIG. 1 , the display board 1 is a rectangular flat plate, and the middle of the top of the display board 1 is rotatably connected with the top of the column 3; the top block 6 is fixedly connected with a sleeve 4, and the top block 6 and the sleeve 4 are both The sliding sleeve is connected to the column 3, and the top block 6 is always in contact with the display board 1. When the top block 6 slides up along the column 3, the display board 1 can be lifted up, so that the display board 1 can be rotated, so that the display board can be adjusted. The display angle of 1; the fixing component is the bolt 5, the peripheral surface of the sleeve 4 is provided with a screw hole, the bolt 5 is threadedly connected with the screw hole and squeezes the column 3, and the top block 6 can be locked and fixed, so that the display board 1 can be locked and fixed. to locate.

The lower end of the top block 6 is provided with two top rods 7. In order to make the force of the top block 6 more uniform, the top rods 7 should be symmetrically distributed on both sides of the column 3; The friction force, the lower ends of the two ejector rods 7 are provided with rollers 8, and the rollers 8 are in contact with the push plate 10, so that the original sliding friction force becomes a rolling friction force, which reduces the resistance and reduces the parts and components. of wear.

In order to make the structure more compact, the edge of the upper surface of the push plate 10 is provided with a lateral limit groove inward, the limit groove penetrates down to the lower surface of the push plate 10, and the upright column 3 is located in the through groove; in order to facilitate the push plate 10 There is also a pedal 9 for stepping on one side of the push plate 10, and the push plate 10 is rotated by stepping on the pedal 9 with the sole of the foot.

The base is provided with two symmetrically distributed vertical supports, the push plate 10 is located between the two supports, and is rotatably connected with the support, and the rotation axis is set horizontally; two vertical springs 11 are connected between the base and the push plate 10 , the springs 11 are symmetrically distributed on both sides of the limit groove; the springs 11 are used to make the push plate 10 and the roller 8 always abut, that is, the force given to the push plate 10 is always upward, which facilitates the application of external force to the pedal 9 can quickly rotate the push plate 10; secondly, it can provide a buffering effect. When the bolt 5 is loosened to make the top block 6 move downward, due to the action of the spring 11, the top block 6 will not fall down quickly, and the push plate 10 will not fall. It will rotate quickly, thus improving the safety in use.

Further, as shown in FIG. 2 , the display board 1 is provided with clips 2 for fixing the display objects. The clips 2 are symmetrically arranged and are rotatably connected with the display board 1. The clips 2 are elastic metal sheets. The clips 2 There are bends protruding to the outside, which is convenient for the rotation and fixed clamping of the clip 2 .

The working process of the utility model is as follows: first place the object to be displayed on the display board 1, and rotate the clip 2 to clamp and fix the object to be displayed. Because the size, shape or display content of the display object is different, sometimes it is necessary to adjust the display board 1 display angle to obtain better display effect; when adjusting, first loosen the bolt 5 to make the top block 6 in a slidable state, and then step on the pedal 9 with the foot to make the push plate 10 rotate, and the push plate 10 is in the slidable state. When it rotates upwards in the vertical plane, since it abuts against the roller 8, the top rod 7 and the top block 6 slide up along the column 3, and the top block 6 and the display board 1 are always in contact, so the top block 6 When moving upwards, it will push the display board 1 to swing upward, so that the display angle of the display board 1 can be adjusted; when it is adjusted to a suitable position, tighten the bolt 5 to fix the top block 6; when the angle of the display board 1 needs to be adjusted in reverse, loosen it After bolts 5, under the pressure of the display board 1 and the self-weight of the top block 6, the top block 6 will automatically slide down, but due to the falling of the spring 11, the top block 6 will slowly fall down to a suitable position, and then tighten the bolt 5 again. Can.

The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Equivalent replacement or modification of the technical solution and its utility model concept shall be included within the protection scope of the present utility model.
