Description
The Board for adjusting vision distance that this utility model relates to is that a kind of rectification people sitting posture prevents bathomorphic instrument specifically.
Existing correcting sitting posture device is that appliance is withstood on the lower jaw place mostly, feels very critical when the people is write, and feels very uncomfortable, makes the student beyond affordability, and carries, installs very inconvenient.
The purpose of this utility model is intended to improve above-mentioned deficiency, provides a kind of dismountable, easy for installation, and proper a kind of Board for adjusting vision distance corrects faulty sitting posture.
In order to achieve the above object, this utility model is to realize like this, it has the table 2 of pressure, base plate 3, top plastron 5, peace one screw 7 on base plate 3, be with a nut 8 on the screw 7, be characterized on top plastron 5, establishing in the plane caulking groove 6, caulking groove 6 built-in portable plates 1, a left side is respectively established in both sides in the middle of the portable plate 1, right pole is gone up fixing hole 15,16, in pressing table 2 left and right planes, respectively establish a left side, right pole caulking groove 11,13, a left side, right pole caulking groove 11,13 two ends are 90 ° of curved grooves, on a left side, right pole caulking groove 11, respectively put left branching rod 12 in 13, right pole 14, a left side, right pole 12,14 two ends are 90 ° of elbows, are pressing table 2 left sides, right both sides respectively are provided with a left side, right pole lower fixed hole 17,18, on base plate 3 centres, establish a shifting chute 9, screw 7 in the plane, nut 8 can move forward and backward in shifting chute 9.
In order to prevent that portable plate from proposing outside the caulking groove 6, be provided with a protruded stigma 4 at portable plate 1 towards the middle and lower part of user chest one side, top plastron 5 is a shaped as frame, the centre is a caulking groove 6, like this, on when carrying portable plate 1, when protruded stigma 4 contacts mutually with the edge of top plastron 5, carry on the meeting prevention portable plate 1, thereby avoided portable plate is proposed from caulking groove 6.
When using, to press table 2 lower planes to put on plane on desk 19 outsides, screw 7 withstands on the desk 19 limit lower planes, the turn of the screw 7, Board for adjusting vision distance is fixed on the desk 19, in caulking groove 6, portable plate 1 is proposed, with left branching rod 12, right pole 14 is from a left side, right pole caulking groove 11, take out in 13, left branching rod 12 two ends are supported on the left branching rod, lower fixed hole 15, in 17, right pole 14 two ends are supported on the right pole, lower fixed hole 16, in 18, at this moment portable plate 1 retaining is in the front, principle by " breast is from desk one fist; books one chi of having hallucinations " is come set screw 7, and screw 7 is being with nut 8 to move forward and backward in shifting chute 9, at last Board for adjusting vision distance is passed through screw 7 and desk 19 fix tightlies.
This utility model is simple in structure, and is easy to use, detachable, is to help the student when doing the homework or read a book, and keeps rectifying sitting posture, prevents bathomorphic a kind of more satisfactory Board for adjusting vision distance.
