The student reads a book, does one's assignment, and upper body can lean against a limit, and leans forward, the nearly books of head rest.Time length a bit will be lain prone on the table, and headrest is on arm.Though these actions form myopia easily, can reduce the pressure of upper body to waist, make sore waist and aching in the waist and the back, fatigue is releived from head to foot.And the vision clipping is ended these actions, and upper body gravity all is pressed onto on the waist, and the time is long slightly, can cause sore waist and aching in the waist and the back, and is tired from head to foot.

2. can cause hunchback.

When waist by the upper body gravity pressure, can arch the back come.For a long time like this, can cause hunchback.

3, vision accompanies necessarily mandatoryly, and having a hunch during use gets in the way is difficult to be subjected to.

The heroic bearing band:

1, has necessarily mandatoryly, during use, be forced to square one's shoulders, two shoulder post-tensionings.

2, after class in the activity, it is unlucky to bend over, and is difficult for accomplishing, hinders action.

The purpose of this utility model is to provide a kind of pressure that can reduce upper body to waist, and stretch the back during use, the heroic bearing vision capsule of unbending pre-myopia prevention.

The purpose of this utility model is achieved in that a kind of heroic bearing vision capsule, include air bag, qi of chong channel ascending adversely ball, base plate and base, air bag upper bottom surface shape is corresponding with the human chest curve shape, and the bottom surface device is on base plate, the base upper bottom surface links to each other with base plate, bottom indent camber or clip is housed.

Compare with the myopic-preventing like product of pre existing, the utlity model has following advantage:

1, air bag and breast contact portion according to the design of human body upper body curve, make chest stressed evenly, reduce the pressure of upper body to waist, relieving fatigue.

When 2, using the back stretch, not crooked, not bow-backed.

3, use is comfortable, nothing is forced, the student takes like a shot.

Below in conjunction with accompanying drawing this utility model being done one describes in detail:

As Fig. 1, a kind of heroic bearing vision capsule is made of rubber balloon 1, qi of chong channel ascending adversely ball 2, two base plates 3 and base 4.

Qi of chong channel ascending adversely ball: material, rubber.Become Sui's orange, long diameter is 8 centimetres, and short diameter is 6 centimetres.It is 1 centimetre of aperture 6 that long diameter one end is opened diameter, and as import department, the backing paste block rubber tissue of ball covers aperture, and effect is to make the gas only import but no export.Another termination interior diameter is 0.7 centimetre a gum elastic catheter 7, is about 15 centimetres.

Rubber balloon: material rubber.Retractility is very little, 12 centimetres of the face widths of going to the bottom, long 16 centimetres, rectangularity; Upper bottom surface resembles isosceles trapezoid, and receives 2-3 centimetre in two waists, and two waists are about 28 centimetres, following about 28 centimetres, about 20 centimetres of top, at the bottom of the middle part in both sides about 2-3 centimetre (Fig. 2).But upper bottom surface is not to do like this, but also in 10 cm range of top middle part, outstanding 5 centimetres (Fig. 3) forward receives 2-3 centimetre (Fig. 4) but also the top is outstanding forward in following simultaneously, also has other shape.The front resembles about 20 centimetres of isosceles trapezoid top, and following 16 centimetres, about 25 centimetres of waist.The back resembles about 28 centimetres of isosceles trapezoid top, and following 16 centimetres, about 15 centimetres of waist.Capsule bottom surface center is to about 20 centimetres of upper bottom surface centre distance, and there is a qi of chong channel ascending adversely mouth at middle part, lateral back, and the qi of chong channel ascending adversely mouth section of having is outward moulded conduit 8, and length is 2 centimetres.

Conduit: length is 2 centimetres, and A end overall diameter is 1.2 centimetres, and interior diameter is 1 centimetre, and B end overall diameter is 1.6 centimetres, and interior diameter is 1 centimetre, B end air bag inwall, and the paste block rubber tissue covers aperture.Conduit has mouthpiece cover outward, and it is 2.5 centimetres that lid has individual aperture and length, and diameter is 0.6 centimetre a small column.

After the qi of chong channel ascending adversely of scalability air bag, become Fig. 1 shape substantially.
