Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 and 2, the myopia prevention corrector comprises a correcting frame 1, wherein the correcting frame 1 comprises a side supporting rod 2 and a positioning support 3, the side supporting rod 2 is arranged on two sides of the positioning support 3, the side supporting rod 2 and the positioning support 3 are fixed through bolts, a clamping plate 4 is fixedly arranged at the lower end of the side supporting rod 2, the clamping plate 4 comprises an upper clamping plate 41 and a lower clamping plate 42, a first screw rod 5 is arranged on the upper clamping plate 41 in a penetrating manner, the first screw rod 5 is connected with the upper clamping plate 41 in a threaded manner, a convex block 51 is fixedly arranged at the outer side end of the first screw rod 5, a knob 52 is sleeved on the convex block 51, a second screw rod 6 is arranged at the upper end of the inner side of the side supporting rod 2 in a penetrating manner, and a nut 61 is fixedly arranged.

Preferably, the two ends of the positioning support 3 are fixedly provided with screws 31, the outer side end of each screw 31 is provided with a nut 32, each screw 31 penetrates through the corresponding side support rod 2, each screw 31 penetrates through the corresponding positioning support 3, and the nuts 32 are screwed and locked, so that the positioning support 3 can be quickly installed.

Furthermore, a plurality of mounting holes 21 are formed in the side branch rod 2, the mounting holes 21 are matched with the screws 31, and the plurality of mounting holes 21 are convenient for adjusting and fixing the positions of the positioning support 3 corresponding to different user requirements.

Preferably, all set up protection pad 7 on location support 3 and the nut 61, can realize through setting up protection pad 7 that the user uses this to correct when putting up 1 with the location support 3 and the contact protection of nut 61, comfort level when improving the use.

Preferably, a contact gasket 53 is fixedly arranged at the inner side end of the first screw rod 5, and the contact gasket 53 can improve the clamping contact surface of the first screw rod 5 and the table board during rotation and locking, so that the fixing effect is improved.

Preferably, the protruding block 51 is a square block, and the protruding block 51 is matched with the knob 52 in an inserting manner, so that the knob 52 can be conveniently and quickly disassembled and assembled for use.

The working principle is as follows: when in use, the correcting frame 1 can be installed and fixed at the front end of the desk plate through the clamping plate 4 so as to assist the user in correcting the head inclination myopia prevention during learning.

When the clamping plate 4 is clamped, the connection with the table plate can be realized through the rotation tightness adjustment of the first screw 5. The rotation of the first screw 5 drives the contact pad 53 at the inner side end thereof to clamp and fix the table with the lower clamping plate 42, the rotation of the first screw 5 can be controlled by the rotation of the knob 52, and the knob 52 is inserted into the projection 51 on the first screw 5, so that after the adjustment and clamping are carried out, the knob 52 can be pulled out and taken down, and further the phenomenon that the clamping stability of the clamping plate 4 is affected due to the looseness of the first screw 5 caused by mistaken touch is avoided. The knob 52 is made of non-toxic PP glue and has threaded insections, so that the knob can be conveniently rotated.
