Description

Angle-adjustable reading rack

Technical Field

The utility model relates to a stationery office supplies especially relates to an angularly adjustable reading frame.

Background

People who have a reading habit currently read books on a desktop in the process of learning and reading, but the reading posture is not correct, and the spine is greatly burdened by long-term low-head reading of readers. And some books can not be spread out evenly, and need the manual pressure of reader to hold, so whole reading process just can not let the people feel relaxed. Or the book is held by hand for reading, although the way is a more correct reading posture, the two hands of the reader cannot be separated from the book, and the reading is inconvenient if the user needs to pick up notes or mark the original text. And the reader keeps the posture of holding the book with both hands for a long time, and certain burden is also existed.

Therefore, the reader can consider using the reading rack to free the hands of the reader, and the subject forms a correct reading habit. At present, reading racks on the market are various in types, but most of the reading racks occupy large space on the structure and are inconvenient to carry. Moreover, the style is single, like the book stand of "a kind of book stand" that the utility model patent of china was published, application (patent) No.: CN201920546093.6, which comprises a reading rack body, wherein the front surface of the reading rack body is rotatably connected with a baffle, the front surface of the reading rack body is provided with a baffle accommodating groove, and the baffle can be embedded and accommodated in the baffle accommodating groove after being rotatably folded; the back of the reading frame body is rotatably connected with supporting legs, the back of the reading frame body is provided with supporting leg accommodating grooves, and the supporting legs can be embedded in the supporting leg accommodating grooves after being rotated and folded. This patent adopts to set up positioning slot on the supporting legs to and the reading stand body back is equipped with the positioning latch tooth that is used for the card to go into positioning slot, thereby realizes the angularly adjustable of reading stand body. However, with such a simple snap-fit structure, the stability of the structure is insufficient. If books themselves are heavier, or the reading frame has received external force to and long-term use back, can produce the supporting legs easily and remove and rock, give user's experience and feel not good.
