Description

Eyesight-protecting unit

This utility model relates to a kind of sight protectio utensil.

Whether the correct set that writes and read a book to be, can directly influence student's vision and healthy.Medical findings shows: the fault of writing and reading a book is to influence adolescent student hypometropia, the principal element of illness such as deformity of spine, hunchback.It is minimum that correct posture can make each organ functional activity machinery of health hinder, and when writing reading, can feel relief eyes indefatigability, learning efficiency height.Past mainly is to rely on theoretical instruction, i.e. the correct posture of student is cultivated in demonstration in propaganda on reason explanation and the action.As long as student one writes without single devotion and read a book, cervical region and the back song that just can turn forward gradually unawares if do not note correcting, will be formed bad readding and write custom, influences healthy but in fact.

At present, published the design of multiple sight protectio utensil in the Chinese patent communique, such as CN86203995 " a kind of ' worker ' font sight protectio frame ", its structure as shown in Figure 1; wherein, 1 supporting plate, 2 supporting plate seats, 3 pillars; the little pillar of 3a, the big pillar of 3b, 4 bases, 5 lock-screws.There is following problem in it: 1 carriage problem, and the device of holding head during use is uncomfortable dumb, and it is tired that user is easy to feel, and 2, orientation problem, in that the location of desktop area occupied is too big otherwise stability is just poor.

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of improved vision protector is provided, and makes it to have long-time use indefatigability, in desktop good stability and the little advantage of area occupied fixedly the time.

This utility model is made up of base, pillar, carriage, it is characterized in that base is equipped with sucker, and be adsorbed on sucker and read on the desktop of writing or workbench, the carriage flexible material, such as rubber, flexible plastic, carriage does not contact with pillar, puts flexible member therebetween.

Because carriage flexible material molding, the lower jaw of user and soft thing coincide and can feel comfortably cool, the flexible member of carriage and intercolumniation makes the flexible carrier can be with lower jaw within the specific limits up and down and the circumference activity, to eliminate the fatigue that keeps a kind of attitude appearance for a long time; Sucker can make location area reduce greatly, and supporting ﹠ stablizing is reliable; Even it is it is smooth smooth that desktop is owed, but because the lower jaw part center of gravity that is placed on the flexible carrier is positioned on the axial line of Body of pillar, and what contact with desktop is dish-shaped rubber parts, under gravity and frictional force effect, still reliable and stable during actual use.

Below in conjunction with accompanying drawing, a better embodiment of the present utility model is described.

Description of drawings:

The structural representation of Fig. 1, CN86203995.

The structural representation of Fig. 2, this utility model embodiment.Wherein, 1 positioning sucker disk, 2 bases, 3 lower supporting rods, 4 lifting columns, 5 springs, 6 bearer carriers, 7 flexible carriers, 8 slots to make way.

Fig. 3, be vision protector outline drawing when carrying.

Fig. 4, be the rigging position figure of Photometer.Wherein, 9 Photometers.

Fig. 5, be the electrical schematic diagram of Photometer.

Referring to Fig. 2, base 2 is adsorbed on by the sucker 1 bottom it and reads on the desktop of writing or workbench, and base 2 is chimeric fixing with sucker 1.Base 2 is threaded with lower supporting rod 3.Screwing in the pillar 3 of lifting column 4, but read according to the different users and to write needed reasonable altitudes free adjustment, its screw thread can also play the fine setting effect, especially correct formed bad when readding the user of writing custom, can regulate height gradually, progressively correct bad readding and write custom, write attitude and hold water up to readding.Metal spring 5(or elasticity of plastics thing) go up and fixedly connected with hood-shaped bearer carrier 6, fixedly connected with lifting column 4 down, cement with binding agent; The hood-shaped edge of bearer carrier 6 is lower than the end face of lifting column 4 slightly; and bearer carrier 6 hangs down between the internal diameter of part and the external diameter of lifting column 4 appropriate gap; depart from the distance of pillar axes during with restriction bearer carrier circle swing, play the effect of protection flexible member and decorative appearance simultaneously again.Whole bearer carrier 6 does not contact with lifting column 4.Flexible carrier 7 and 6 chimeric connections of bearer carrier make easy accessibility.Flexible carrier 7 can be made into difformity, to adapt to all ages and classes people's needs.During use, lower jaw part is placed on the universal flexible carrier 7, in readding the process of writing, can be axially or circumference fine motion freely, and avoided existing design carriage member stiff uncomfortable, dumb.The sucker location of base is convenient, and area occupied is little.Time spent lifting column 4 can not screw in the lower supporting rod 3, as shown in Figure 3, can be placed on like this in school bag or the pocket, and is easy to carry.In addition, can also electronic light metering device be set in pillar, as shown in Figure 4 and Figure 5, help the student to judge whether light is suitable, when the illumination of writing and reading a book is lower than 100 luxs, lumination of light emitting diode, indication is read the person of writing and is in time turned on light or improve and read write condition.Have the design of machinery and the dual eyesight protection function of electronics, make product more perfect, practical.
