The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

It should be noted that the top and bottom of each portion with good vision are distinguished according to the distance from the user, the end far from the user is the top, the end near to the user is the bottom, the right side in fig. 1 is the end far from the user, the left side is the end near to the user, or according to the up-down direction in fig. 1 and fig. 2, the top is the top, and the bottom is the bottom. Specifically, the book rest 100, the plate 110, and the inclined plate 120 are top ends on the right side and bottom ends on the left side in the direction in which the posture corrector for a vision frame in fig. 1 is in this state. Also in the orientation of the posture corrector for a sitting posture of a vision frame shown in fig. 1, the top end is above the chest plate 200 and the table plate 300, and the bottom end is below the chest plate. While the lateral wall of the chest plate 200 is the right side wall in fig. 1 and the medial wall is the left side wall in fig. 1.

Referring to fig. 1 to 5 together, the embodiment provides a sitting posture corrector for eyesight rack, comprising a book placing plate 100 and a chest baffle 200; the sitting posture corrector of the eyesight frame further comprises a desk stopper 300, wherein the top end of the desk stopper 300 is hinged with the bottom end of the book placing plate 100, and the bottom end of the desk stopper 300 is hinged with the bottom end of the chest baffle 200; the vision rack sitting posture corrector also comprises a clamping mechanism 500, and at least one position of the chest plate 200 except the bottom end thereof can be oppositely clamped with at least one position of the desk baffle 300 except the bottom end thereof through the clamping mechanism 500.

The user can place a book on the book placing plate 100 and adjust to a proper viewing state. Then, after the bottom end of the table stopper 300 is hinged to the bottom end of the chest flap 200, the table stopper 300 and the chest flap 200 can be folded or unfolded relatively, and when the table stopper 300 and the chest flap 200 are folded, the inner side wall of the chest flap 200 can be connected to and opposed to the table stopper 300. Since the bottom end of the table stopper 300 is hinged to the bottom end of the chest board 200, the engaging mechanism 500 is connected to other positions of the table stopper 300 and the chest board 200, the other positions are positions other than the position where the bottom end of the table stopper 300 is hinged to the bottom end of the chest board 200, the other positions can be located in the middle of the table stopper 300 and the chest board 200, the top of the middle of the table stopper 300 and the chest board 200, or any other positions, and the table stopper 300 and the chest board 200 can be relatively engaged and fixed by connection. The engaging mechanism 500 can be used for relatively engaging the desk stopper 300 with the chest flap 200, or can be used for relatively separating the desk stopper 300 from the chest flap 200, so as to switch the use state and the storage state of the sitting posture corrector of the eyesight rack.

Of course, in addition to this, the table stopper 300 and the chest plate 200 may be fixed by other means, or the fixing may be further strengthened by other means in combination with the fastening mechanism 500. For example, a first magnetic member (not shown) is disposed on the adjusting member 400, a second magnetic member (not shown) is disposed on the inner sidewall of the desk stopper 300, and the first magnetic member and the second magnetic member have a mutual magnetic attraction effect, so that the adjusting member 400 and the inner sidewall of the desk stopper 300 are magnetically attached and connected to each other, and the use state of the vision frame sitting posture corrector is switched. Moreover, the first magnetic member and the second magnetic member are magnetically attracted to each other, so that the adjusting member 400 and the inner side wall of the table stopper 300 are connected with each other, and the desk has the advantages of being convenient to disassemble and assemble, and convenient for students to operate and use. The magnetic coupling system may be used together with the engaging mechanism 500 or may be used alone.

After the desk blocking piece 300 is connected with the chest baffle 200 oppositely, the book placing plate 100 can be placed on the upper surface of the desk, the desk blocking piece 300 can abut against the side wall of the desk, and the chest baffle 200 is in a vertical state at the moment and can be used for abutting against the chest of a student, so that the reading posture of the student can be adjusted.

Further, the adjusting piece 400 is further included, the adjusting piece 400 is arranged on the inner side wall of the chest baffle 200 and is linearly and slidably assembled with the chest baffle 200 along the longitudinal direction of the chest baffle 200; the table stopper 300 is clamped with the adjusting member 400 through the clamping mechanism 500, and further clamped with the chest baffle 200.
