Abstract
The utility model discloses a nearsightedness preventing book holder, which comprises a bottom plate, a panel, a bracket, a light measuring device, a distance measuring device, an adjustable-light lamp and the like, wherein the inclination of the panel can be adjusted by adjusting the bracket so as ensure the optimal view angle of a user. The light measuring device can adjust the brightness of the adjustable-light lamp according to the intensity of the light rays on the panel and can automatically turn off the lamp and remind the user through an acousto-optic alarm when the intensity of the light rays is too high. The distance measuring device can detect if the sitting posture of a reading or writing person is correct, and the alarm gives an acousto-optic alarm to remind the user to sit in a correct posture if the head and the chest of the user are too close to a book and a desk. Thus, the sight and backbone of the user are protected.
Description
Technical field
The utility model relates to a kind of schooling apparatus, and specifically a kind of light that carries is regulated, and sitting posture is measured, the myopic-preventing holder bookshelf of eyeshield.
Background technology
When reading study, generally all books are lain on the desk and read, but time one length will be felt to be far from suitable, and the books or the data of reading with handgrip holds up often, to adapt to the visual angle of oneself, otherwise eyes can be uncomfortable and tired, sees that in general the sight line of thing is parallel or best near looking squarely reading, and the degree of fatigue of eyes and stravismus are than easily a lot, our reading that is seated at ordinary times lies in books on the desk.Sight line is downward-sloping, and eye muscle is in extended state for a long time, so eyes are felt fatigue easily, abnormal sitting posture in addition, sighting distance is too near, and light all is the unfavorable factor that causes myopia too secretly or too strongly, and abnormal sitting posture also can cause spinal curvature etc. for a long time.
The utility model content
The reading article that keep flat when reading a book in order to overcome on the table cause the strong and weak deficiency that causes myopia of asthenopic defective and abnormal sitting posture and light, the utility model provides a kind of myopia prevention bookshelf, this bookshelf can not only be aligned and read the angle of inclination that thing is placed, to adapt to reader's best line-of-sight, alleviate the eye fatigue that long-time reading causes, and carry the light self-checking device, light on the reading face can be adjusted within the optimum range, in addition, also with rangefinder, the person does not lean on too closely with books to remind reading face, in order to avoid cause myopia and spinal curvature.
The utility model solves the technical measures that its technical problem takes, and base plate is connected with hinge with one of panel, and the lateral ends of panel connects carriage with minor axis, and carriage is made with metal, and the lower end has circular hole.One side of corresponding carriage is installed several cylindric pins at the base plate edge, and the diameter of pin is less than the circular hole of carriage, and carriage cooperates with circular hole, and the angle of inclination of panel can be adjusted in the position of selecting the pin position to cooperate with circular hole, adapts to reader's optimal viewing angle.Base plate is set as hollow, and rangefinder, photometer, voltage regulator and battery etc. are installed in base plate.Two desk lamps with dimmer switch that metal hose connects of drawing are installed in the upper end of panel, the adjusting of this light is to control by the photometric system (prior art) that is installed in the base plate, it can regulate light according to the light power on the panel, that is to say when light on the panel is too dark, the light of desk lamp with dimmer switch is just strong, if the light on the panel is too strong, desk lamp with dimmer switch is closed, and sends the sound and light prompt.Plate washer is set below panel, a range finding probe (prior art) is installed on plate washer, this range finding probe is measured from both direction, and the one, survey the distance vertical with panel, be that control reader's head does not lean on too closely with panel; The 2nd, the distance of survey shirtfront and desktop reminds the reader to keep certain distance with desktop, and the comprehensive function of the two is to make the reader can keep correct sitting posture.Range unit also is provided with " mode " adjusting knob, and it can regulate " reading " and " writing " two kinds of modes.If be adjusted on " writing " mode, that is to say whether measurement is correct at the sitting posture that the bookshelf plate writes, if incorrect, the telltale that is installed on the bookshelf baffle plate will be pointed out, thereby reaches the purpose of vision protection, vertebra in front.
The beneficial effects of the utility model are, provide the holder thing that to regulate visual angle and light to the reader, alleviate because of the long-time caused eye fatigue of reading of reading, in addition, also carry reading, the monitoring device of the sitting posture that writes, avoid the myopia and the spinal curvature that cause because of abnormal sitting posture.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a kind of structural representation of myopia prevention bookshelf.
Fig. 2 is a kind of circuit theory diagrams of myopia prevention bookshelf.
Among the figure, 1, panel, 2, minor axis, 3, base plate, 4, carriage, 5, straight pin, 6, circular hole, 7, hinge, 8, telltale, 9, photometry probe, 10, range finding probe A and B, 11, power knob, 12, baffle plate, 13, select knob, 14, power line, 15, line ball, 16, desk lamp with dimmer switch, 17, voltage regulator, 18, battery, 19, charger, 20, rangefinder, 21, photometer.
The specific embodiment
In Fig. 1, the lower end of panel 1 is connected with hinge 7 with an end of base plate 3, the side end face of panel connects carriage 4 with minor axis 2, circular hole 6 is opened in the lower end of carriage, the end face of the corresponding carriage of base plate is provided with several cylinders pin 5, and the circular hole of carriage can be inserted in the straight pin, changes the position that carriage is inserted in straight pin, can regulate the angle of inclination of panel, to adapt to reader's optimal viewing angle.In the lower end of panel baffle plate 12 is set, prevents that these books from gliding, baffle plate is made hollow, the probe A of rangefinder is installed in the upper end of baffle plate, to predict the distance of reader's head and panel, the probe B of rangefinder is installed in the front of retaining, knows the distance of reader shirtfront and desktop with side.The probe 9 of photometer is installed the middle position of baffle plate upper surface, can in time predict the light intensity on the panel.The telltale 8 of range finding, photometry is light and buzzer, is installed in a side of baffle plate upper end.Power switch 11 is installed in the opposite side of baffle plate upper end, and power line 18 inserts in the base plate, in the interlayer of base plate, rangefinder and photometer is installed with voltage regulator and battery etc.Select knob 13 to be installed in the outside of power knob, when selecting button in " readings " position, bookshelf should be placed on close reader's the desktop, if when knob being chosen in " writing " position, should reserve the position of writing on the desktop before the bookshelf, that is to say that bookshelf is far away from the person of writing.Line ball 15 is used elastomeric material system, and an end is fixed on the end face of panel, and other end knot that can be undone by a pull is fixed on the panel opposite side.Desk lamp with dimmer switch 16 usefulness metal hoses are installed in the upper surface of panel, are controlled by the photometer in the base plate.
