Description
Technical field
The utility model relates to a kind of student eyesight protection apparatus, relates in particular to a kind of pre-myopia prevention read-write protection frame.
Background technology
Adolescent student is in read-write; usually the labour contractor buries very lowly unconsciously; even lie prone on desk; because read-write posture is incorrect; time has been grown; the incorrect read-write posture of adolescent student is difficult for being repaired, and can cause student eyesight to descend the eyesight that has seriously endangered adolescent student.Some vision corrections or read-write posture apparatus for correcting appear now on the market, but its complicated structure, and cost is higher, brings great financial burden for the head of a family of adolescent student, therefore can not get applying on a large scale.
The utility model content
The posture that technical problem to be solved in the utility model provides a kind of teenager of rectification when reading and writing guarantees the correct of read-write posture, the prevention adolescent myopia, and vision protection, simple in structure, with low cost, the pre-myopia prevention read-write protection frame that is fit to apply.
For solving the problems of the technologies described above; the technical solution of the utility model is: pre-myopia prevention read-write protection frame; comprise the hydraulically extensible montant; described hydraulically extensible montant bottom is connected with flexible cross bar; described flexible cross bar is connected with the connection clip of clamping desk edge, and described connection clip is provided with fastening bolt, and the top of described hydraulically extensible montant is connected with lower jaw support; described lower jaw support is provided with inserting groove, and described inserting groove activity is plugged with the read-write baffle plate.
As preferred technical scheme, described hydraulically extensible montant be connected the connection of flexible cross bar and be " L " type.
As to improvement of the technical scheme, described fastening bolt is installed in the below of described connection clip.
As to further improvement in the technical proposal, described read-write baffle plate is green light-passing board.
Owing to adopted technique scheme; pre-myopia prevention read-write protection frame; comprise the hydraulically extensible montant; described hydraulically extensible montant bottom is connected with flexible cross bar; described flexible cross bar is connected with the connection clip of clamping desk edge, and described connection clip is provided with fastening bolt, and the top of described hydraulically extensible montant is connected with lower jaw support; described lower jaw support is provided with inserting groove, and described inserting groove activity is plugged with the read-write baffle plate.Described connection clip is clamped in desk edge, tightening described fastening bolt fixes, use the described flexible cross bar of adjusting and described hydraulically extensible montant according to the individual, when determining read-write and the horizontal and vertical distance of desk, when the teenager reads and writes, make described lower jaw support hold lower jaw, so just fixed when the teenager reads and writes and the horizontal and vertical distance of desk.Described hydraulically extensible montant support force is large, supports unstable when avoiding using.According to the individual demand described read-write baffle plate of can pegging graft, the posture when further correcting read-write.Posture when the utility model rectification teenager reads and writes guarantees the correct of read-write posture, the prevention adolescent myopia, and vision protection, simple in structure, with low cost, be fit to apply.
