Fig. 1, has the principle schematic of the myopia prevention desk of forcing function of use

The utility model is further described with embodiment below in conjunction with accompanying drawing:

The myopia prevention desk of the utility model design is made of the backing plate 1 that writes, support 3, baffle plate 7, base 2, as shown in Figure 1.The end of backing plate 1 of writing is fixed on the bottom of base 2, and the upper left quarter of base 2 has a side channel 5, and side channel 5 is the rectangular channel of back opening, and the right-hand member of side channel 5 has the notch of forward and backward and end face opening, and width of rebate is a bit larger tham the body of rod width of support 3.Baffle plate 7 is contained on the support 3, and is parallel with support 3.There is a borehole jack 4 lower end of support 3, borehole jack 4 is 90 ° of angles with support 3, borehole jack 4 places in the side channel 5, with fixed axis 6 pinnings more a little bit smaller slightly than its aperture, support 3 can be rotated around fixed axis 6 at the notch place of side channel 5, at ordinary times support is put down together with baffle plate, overlap with the backing plate that writes, easy to carry and store.Support 3 can also be along fixed axis 6 move left and right, during use, support 3 is erected, with write 1 one-tenth 90 ° on backing plate, the borehole jack 4 of support 3 bottoms can be pushed the left end of side channel 5 along fixed axis 6 to, because the cross section of borehole jack 4 and the section of side channel 5 coincide, support 3 is locked therefrom, so just can prevent to bow forward or left when the student from writing.In addition, write below the backing plate in the lower end of support 3 extend through slightly, causes desk can only be placed on the edge of desk in use, can prevent to turn around simultaneously use again.

The backing plate 1 that writes is the positive thin plate that is suppressed with fine and close groove line, be generally plastic plate, make writing be coin outer rim zigzag, so that make the teacher and head of a family supervision and inspection, in order to prevent the student head is leaned against on the support 3, have some plastics thorns 3 on the cross bar of support 3, plastics thorn on its shape such as the curler, feel under the weather when oppressing but lack a little making, because the plastics thorn is soft, the unlikely injury.

So far, all introduced technology contents of the present utility model.
