Why don t the desks in the school be oblique?

Some experts have studied it, and I still remember the kind of slanted one that could be lifted in junior high school.

Uncover the six major crimes of the study table.

1. Hurt: 12 degree inclined plane.

The design is seriously irrational, without any scientific basis, just a selling point that fools people. Like a flat table, it makes people adapt to its unreasonable state, which is harmful to the health of the body and mind. The state stipulates that the desktop is stepless adjustment from 0 to 12 degrees.

2. Harmful: It is said that there is a dual-purpose function of plane and oblique plane, and there is a height difference of 12 cm between the two states, which is more harmful to use, and children are more likely to get myopia and hunchback.

3. Illegal: The structure of the three main functions of the 12-degree slope of the study desk, the leveling method or the height adjustment seriously violates the national standards for desks and chairs. Parents who can overturn their views will receive a reward of 50-12,000 yuan (the right of interpretation belongs to the center).

4. Depreciation: More than eighty percent of children use plane functions to depreciate by more than half. If you don't adjust it in time, it will hurt your child even more!

5. Backwardness: In the forties and fifties, primary and secondary schools and universities used inclined tables, but they were gradually eliminated because they found that fixed inclined planes were harmful.

6. Deception: The manufacturer boasts that the learning table has the effect of correcting the sitting posture and preventing camel eye protection by relying on a single inclined plane; There is also a famous Chinese brand, produced in a big city, in fact, it is fake, the small industry of learning desks has no brand at all, and it is generally produced by individual manufacturers in remote rural areas.

It's easy to draw, if it's flat, then you still have to draw across the table from a distance?

And it's convenient**, flat, and when it's big, isn't it an oblique two-sided projection? It's not real.

It is to correct the student's sitting posture and protect the student's spine. In the past, homework was written on the desk, but now it is not needed, which is more convenient for students to see.

It is good to oblique to prevent reflection and read a book.

There are several uses for your question.

First, it is convenient to browse newspapers and other learning materials.

Second, it is for design, which is convenient for drawing design drawings, and there are many such tables in my school for us to draw.

Let you concentrate on your studies, don't lie on the table...

There is 1 fixed inclined plane and 1 plane of learning desk, the production process is simple, the structure of 12 degrees and other fixed dead inclined planes is not scientific, the angle is too small when reading, and the angle is too large when writing, which can not meet the health requirements of students. Adjust from the inclined plane to the plane, raise the table by 12 cm, and use it alternately every day, the child may be myopic at 3 to 5 months, and the cervical and lumbar spine are uncomfortable. There are only faulty slopes and planes, so why are there no 3rd and 4th inclined planes for children to choose?

After all, more than 8 children use a plane without an inclined plane, no matter how good the function is, the child does not use it, and 1 cut is equal to zero. As early as 10 years ago, primary and secondary schools and universities at home and abroad used inclined desks, and later found that they had many shortcomings and gradually eliminated inclined desks, but young parents did not know this history. In short, this is a man-made concept of hype, misleading parents, poor use effect, harmful to health, belongs to the history of the elimination of old products, low function, the greatest harm, more on the market, the price is about 200 yuan, about 500 yuan, about 900 yuan, about 1800 yuan.

It feels bad about the bevel! The inclined table should be perfectly matched with the height of the chair, and it will be uncomfortable to sit if there is a slight mismatch, and it would be slightly better if the height could be adjusted. In addition, the beveled table is easy to drop things and get annoying.
