Embodiment 1

[0058] See image 3 As shown, it is an exploded view of the vision protector of the present invention.

[0059] The head 1 includes a front panel 111, a rear panel 112, a head adjustment hole 113 arranged on the front panel 111, an ear structure (barto pad 121, protruding ear 122, snap-in block 131) and a height of the head. Regulatory structure.

[0060] The positioning portion 2 includes a first positioning end 21 and a second positioning end 22 .

[0061] The spinal rod 3 includes a first positioning section 31 and a second positioning section 32 .

[0062] The front panel 111 and the rear panel 112 form a stable fixed connection through, for example, clamping, screw connection, etc., to form a head shell, and an accommodating cavity is formed between the front panel 111 and the rear panel 112 , the accommodating cavity is used to accommodate the upper end of the spinal rod 3;

[0063] A through slot is formed on the upper part of the head shell for fixing the ear struc...

Embodiment 2

[0071] See Figure 5 As shown, it is a schematic structural diagram of the vertebral rod 3 in Embodiment 2 of the present invention.

[0072] Embodiment 2 On the basis of Embodiment 1, the circular first positioning hole 311 on the first positioning section 31 is changed to Figure 4 The square positioning hole 312 described in, because the circular positioning hole has the same radius up and down, left and right, because the eyesight protector described in the present invention is not a precise mechanical structure, and, in consideration of safety, various structures have been made There is no sharp-angled structure to ensure the safety of users. Therefore, in order to ensure that the first positioning pin has a larger size, the first positioning hole 311 will be made larger, and the first positioning hole 311 will be made larger. The problem brought by the large size is that the interval between the holes will be relatively large, so if the user wishes to finely adjust the ...

Embodiment 3

[0076] See Figure 6 As shown, it is a structural schematic diagram of the third spinal rod 3 in the embodiment of the present invention.

[0077] The third embodiment is similar to the first embodiment, the difference is that the first positioning section 31 adopts tooth lines 314 instead of the first positioning hole 311 in the first embodiment or the square positioning hole 312 in the second embodiment , such a structure can achieve better fine-tuning.

[0078] The upper surface of the serration 314 may have a radian, but the lower surface should not have a radian, so as to improve the fastening firmness.

[0079] The first locating pin in the third embodiment should be a straighter locating pin flatter than the square locating pin in the second embodiment, so as to cooperate with the tooth pattern 314 to form a clamping connection.

[0080] It should be noted that, for the two-stage height adjustment structure and the deformation of the height adjustment structure provid...

Abstract

The invention discloses a vision protecting device. The vision protecting device comprises a vision protecting device body. The vision protecting device body comprises a head arranged at the top end, and is characterized in that the head comprises a head shell and a chin supporting pad, and the chin supporting pad is located at the top of the shell and fixedly connected with the shell in a detachable mode. The vision protecting device has the advantages that as the chin supporting pad convenient to replace is arranged at the head at the top end, when a user uses vision protection, and the chin abuts against the chin supporting pad, the user can have the good touch feeling, and replacement is convenient; as an ear structure is arranged, when the user laterally slides, the certain correcting effect can be given; as an outer cover is arranged, the user can select the texture of the outer cover by himself and can replace the appearance of vision protection by himself.

Description

technical field [0001] The invention relates to the field of auxiliary health care equipment, in particular to a vision protector. Background technique [0002] In order to help children use their eyes scientifically when reading and studying, overcome bad habits such as bowing their heads and hooking their backs when studying, and protect their eyesight and cervical spine. By fixing the "eye protection frame" on the side of the desk directly in front of the learner, the learner can freely adjust the appropriate height according to his height, and put his chin on the bracket of the eye protection frame to maintain the distance between the learner's eyes and the book It is about 35cm, so as to correct students' bad habits such as tilting their heads, bowing their heads, and hooking their backs, reducing the pressure on the cervical spine caused by long-term reading and writing, and preventing myopia and hunchback. [0003] When the eyesight protector is working, when the use...
