Abstract

The utility model relates to a vision correcting rack, which is used for preventing and correcting myopia and mainly comprises an upper triangle, a Y-shaped rack, a chest blocking board, a chest digging pin, a scale post, a belly blocking pin, a belly digging pin, a fixing rack, etc. The utility model is characterized in that the upper triangle and the Y-shaped rack are connected through a clamping mouth, the chest blocking board is connected with the Y-shaped rack through a chest control pin for controlling a distance between a chest and a desk and the uprightness of shoulders and a waist, a belly blocking board is connected with the scale post through a belly control pin for controlling a distance between a belly and the desk, the belly blocking board is connected with a toothed concave through a movable screw, height can be adjusted at will and the lower end of the scale post is connected with the fixing rack. When the vision correcting rack is used for middle school students and pupils who need to read books and write, the utility model can forcibly control correct sitting postures of the students and scientific eye use and achieves the purposes of preventing and correcting the myopia.

Description

The vision correction frame

One, technical field:

The utility model relates to a kind of vision correction frame that pre-myopia prevention and myopia correction are used.

Two, background technology:

Students in middle and primary schools are bad at present causes the myopia of student rate to increase with the eye custom, and primary and secondary students are because the age is little, and eyeball plasticity is very high, self-control is very poor, often reads a book on all fours and writes, close eye, just cause asthenopia easily, ciliary spasm, thus cause myopia.Myopia is not sayed student's harm and is known, the electronic product of original a kind of pre-myopia prevention is to take with oneself, when your abnormal sitting posture, just remind you, but students in middle and primary schools' self-control is very poor, singly is that prompting is not enough, does not have a kind of product can force student's science eye, and myopia has been arranged, most of can select to wear glasses rectifications, wear glasses that it is just high more only can to wear the number of degrees more, and not have a kind of product by its recovery nature regulatory function.

Three, summary of the invention:

At the above-mentioned shortcoming that exists, the problem that the utility model need solve and the technical scheme of proposition are the defectives that overcomes prior art, a kind of vision correction frame that provides pre-myopia prevention of a kind of suitable students in middle and primary schools and myopia correction to use.The technical scheme of the utility model vision correction frame: it comprise triangle (1), wye bearings (2), retaining plastron (3), control abdomen pin (4), gear screw (5); Fixed screw (6), scale pillar (7), retaining web (8), control abdomen pin (9), left fixed mount (10), right fixed mount (11), mark of mouth (12), the feature of this vision correction frame: be that triangle (1) is connected by bayonet socket with wye bearings (2), shelves plastrons (3) are connected with wye bearings (2) by control chest pin (4), the chest that is used for controlling well is vertical with waist with distance, the shoulder of table, and gear screw (5) and fixed screw (6) are contained in the bottom of wye bearings (2); Scale pillar (7) flexibly connects with the wye bearings bottom by mark of mouth (12) and gear screw (5), can arbitrarily adjust height; Retaining web (8) be connected with scale pillar (7) by controlling abdomen pin (9), control the distance of belly and desk well, the lower end of scale pillar (7) is connected with right fixed mount (11) with left fixed mount (10), plays the fixedly effect of desk and brace.The utility model vision correction frame material adopts plastics or metal material.In sum, the utility model writes when using when students in middle and primary schools reading, can control sitting posture of student and rectify, and science reaches the purpose of pre-myopia prevention and myopia correction with eye.

Four, description of drawings:

Fig. 1 is the utility model vision correction shelf structure schematic diagram.、

Among the figure: 1, go up triangle, 2, wye bearings, 3, the retaining plastron, 4, control chest pin, 5, the gear screw, 6, fixed screw, 7, the scale pillar, 8, the retaining web, 9, control abdomen pin, 10, left fixed mount, 11, right fixed mount, 12, mark of mouth.

Five, specific embodiments:

Be described further below in conjunction with the use of accompanying drawing: at first with a left side the utility model vision correction frame, right fixed mount (10,11) be fixed on the desk edge, be seated, chin strap is at triangle (1) recess, chest is pasting retaining plastron (3), and belly is pasting retaining web (8), and books keep flat on the table, with left hand fixed screw (6) is loosened, be transferred to the position of " 0 " with right hand transmitting gear screw (5), watch bookish word, if do not see, toward downward modulation, till seeing clearly, " 0 " following you are myopia, thus will be gradually toward raising, could regulate the ciliary muscle of spasm, recover former eyesight, often do eye exercises and look far into the distance, effect can be better.Mainly to liking students in middle and primary schools, easy to use, vision protection reaches the double effects of pre-myopia prevention and myopia correction, and for you mould a proper sitting posture, helps healthy effect the utility model better.
