Description
The utility model relates to a kind of collapsible Eye health apparatus, especially is installed on primary and secondary students' desk rectifying sitting posture of student, the collapsible Eye health apparatus of pre-myopia prevention, hunchback.
At present, known desk has two types with the eye protection device: a kind of employing sieve silk is fixed and is adjusted, and uses too complicated, not easy to operate; Another kind of employing female type, though more simple and convenient than the former, the problem of back collection keeping of finishing using that the two is all unresolved is owing to be mainly used in primary and secondary students, so damage unavoidably and lose.

The utility model is achieved in that a block length square plate, and the bottom is provided with whippy folder formula bearing.Folder formula bearing and fixed head are spring hinge type link joint, and it is folding to make 180 degree between the two.Fixed head and desktop bottom is fixedly connected, after be provided with guide groove.
After the student finishes using, only need against the force of the spring, rectangular slab is placed horizontal, the guide groove of secured in alignment plate pushes gently and gets final product.Otherwise, only need along continuous straight runs to extract rectangular slab gently out during use, when its bottom disengaging guide groove, the strength of spring just can make folder formula bearing reach vertical duty together with rectangular slab.
Adopt such scheme, improved the globality of desk and Eye health apparatus effectively, not only more convenient to use, and be convenient to keeping, avoid damaging or losing.
Below, in conjunction with the accompanying drawings and embodiments the utility model is further specified:
Figure one is the schematic diagram of the utility model in practice.
Figure two is design sketch of the collapsible collection of the utility model.
Figure three is the utility model critical piece " folder formula bearing and fixed head etc. " structure charts.
1. desktops among the figure, 2. rectangular slab, 3. folder formula bearing, 4. fixed head, 5. spring hinge, 6. guide groove.
In figure one, Eye health apparatus is in running order, and rectangular slab (2) bottom is by folder formula bearing relative fixed.Because the high resilience of folder formula bearing is so strength just can make rectangular slab slidably reciprocate betwixt a little.
In figure three, folder formula bearing (3) connects by spring hinge (5) is movable with fixed head (4).Spring hinge (5) acts on folder formula bearing (3), make its can be when opening and using together with rectangular slab (2) bullet to vertical duty.After finishing using, rectangular slab (2) to back lower place pressure a little, just can overcome spring strength, is made it horizontal, aim at guide groove (6) then and push desktop (1) and get final product (as figure two).
The utility model is that raw material is made with plastics and sheet metal.
