Description

Desk support capable of preventing myopia

Technical Field

The utility model relates to a prevention myopia technical field, concretely relates to desk support that can prevent myopia.

Background

In 2018, a research report of the world health organization shows that myopia patients in China reach 6 hundred million, the myopia rate of teenagers is the first in the world, the myopia rate is still on the rise and is getting younger and younger, and the incorrect sitting posture during reading and writing is one of the causes of myopia. When reading and writing, students always lean forward and read and write with their heads buried, and the distance between eyes and books is very close, which becomes one of the causes of myopia in the long run. Although some desk supports for preventing myopia of students exist at present, a non-retractable support is fixed on a desk mostly, and the forward leaning of the body of the student during reading and writing is avoided, but the non-retractable support can not be used for enabling the student to lie prone on the desk for rest during noon break, so that the rest of the student is influenced. In addition, some desks are provided with retractable supports, but the bottom ends of the supports are fixed on the desks only through bolts and nuts, and the supports can deflect when students push the desks forcefully, so that the aim of correcting sitting postures cannot be fulfilled.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve is that the fixed desk support of current prevention myopia can not receive and release, influences student's rest and activity to the fixed not firm technical problem of support, aim at provides the desk support that can receive and release and fix firm prevention myopia.

The utility model discloses a following technical scheme realizes: a desk support capable of preventing myopia comprises a desk plate, a bookshelf, buckles, supports and supporting hooks, wherein the bookshelf is arranged on the desk plate, the supports are U-shaped and movably connected with the bookshelf and used for being propped against the upper edge of a sternum of a student, the buckles are respectively arranged on two side edges of the desk plate, the supporting hooks are movably connected on the supports, and free ends of the supporting hooks are inserted into the buckles and used for limiting rotation of the supports.

In order to prevent the myopia of students and facilitate the rest of the students, the technical proposal is that a bookshelf and a support are arranged on a desk plate, a hasp is arranged on the side edge of the desk plate, the bookshelf is fixed on the desk plate through a bolt, the support is U-shaped and is movably connected with the free end of the bookshelf through an open bolt, a support hook is movably arranged on the support, and the support is connected with the hasp through the support hook. When the support is used, the support is turned over above the desk plate, the supporting hooks are inserted into the buckles, the support is fixed through the supporting hooks, the fixed support is just propped against the upper edge of a sternum of a student, the hands of the student can move freely below the support, but the head of the student cannot cross the support under the limitation of the support, and therefore the purpose that the body of the student leans forward to cause myopia when the student reads and writes is achieved. When the student needs to have a rest, the support hook is separated from the hasp, and then the support is turned over to the lower side of the desk plate, so that the rest of the student is not affected. Compared with the prior art, the bookshelf is fixed on the desk plate, and the bracket is movably arranged on the bookshelf through the open bolt, so that the bracket can be turned upwards or downwards to realize free folding and unfolding, the practicability and convenience of the bracket are improved, and the influence on the rest of students is avoided; meanwhile, the position of the support is fixed by the hasps and the supporting hooks, the structure is simple, the operation is convenient and easy, the support is firm and stable, and the support is prevented from being deflected when stressed to lose the myopia prevention function.

In addition, the height of the students with faster body development in the early high school stage is higher than that of the students in the same age, and the heights of the desks in one class are mostly the same, so that the heads of the students with higher heights are farther away from the desk plate, and the students with higher heights lean forward and bury heads for reading and writing when reading and writing words in the long-term learning process, so that the spines of the students bend and deform, and the hunchback of the students is caused.

Furthermore, the support comprises a beam section and side sections, one end of each side section is vertically arranged at two ends of the beam section, and a free end of each side section is provided with a first through hole for inserting an open plug pin; and the side edge section is also provided with a side ring, and the side ring is movably connected with the supporting hook.
