Utility model content:
The utility model, in order to make up the deficiencies in the prior art, provides a kind of sight protector, reasonable in design, the Distance geometry posture can us reminded at any time to read, keep fit when writing, and reduces the probability of myopia, solves problems of the prior art.
The utility model for solving the problems of the technologies described above adopted technical scheme is:
A kind of sight protector, comprise a box body, the battery chamber that opening is arranged is provided with in the front of box body, dry cell is provided with in battery chamber, the opening part of battery chamber is provided with battery cover, clamping device is provided with at the box body back side, the end face of box body is provided with flicker attention gatter, an infrared emission sensor is respectively equipped with in the end face left and right sides of box body, infrared receiver sensor is provided with in the end face centre position of box body, monitoring distance by-pass cock is provided with in the side of box body, power switch is provided with at the opposite side of box body, control device is provided with in box body, described flicker attention gatter, infrared receiver sensor, two infrared emission sensors, monitoring distance by-pass cock is connected with control device respectively by wire, control device is connected with dry cell through power switch by wire.
Described clamping device comprises the horizontally disposed upper buckle be installed on the box body back side, box body below upper buckle two ends is provided with two slideways vertically arranged, the two ends of one lower pinch plate be arranged in parallel with upper buckle are placed in two slideways respectively, upper buckle is connected by a bolt with between lower pinch plate, upper buckle is provided with a through hole, lower pinch plate is provided with the threaded hole corresponding with through hole, and upper buckle and lower pinch plate are connected as one through through hole and threaded hole by the screw rod of a bolt closed with corresponding threaded holes successively.
The lower surface of upper buckle and the upper surface of lower pinch plate are equipped with rubber blanket.
A groove is provided with near the position of battery chamber in the front of box body.
The utility model adopts such scheme; reasonable in design; the distance of child's head to desktop can be monitored; by reading, write time attitude not just, near-distance reading effectively monitors, reminds; when monitor the distance of child's head to desktop be less than preset distance time; the flicker of flicker attention gatter is reminded, and is conducive to protection eye health and corrects the wrong sitting posture such as elbow, hunch.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Fig. 3 is the left TV structure schematic diagram of Fig. 1.
In figure, 1, box body, 2, battery chamber, 3, flicker attention gatter, 4, infrared emission sensor, 5, infrared receiver sensor, 6, monitoring distance by-pass cock, 7, power switch, 8, upper buckle, 9, slideway, 10, lower pinch plate, 11, bolt, 12, rubber blanket, 13, groove.
Embodiment:
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
As Figure 1-3, a kind of sight protector, comprise a box body 1, the battery chamber 2 that opening is arranged is provided with in the front of box body 1, dry cell is provided with in battery chamber 2, the opening part of battery chamber 2 is provided with battery cover, clamping device is provided with at box body 1 back side, the end face of box body 1 is provided with flicker attention gatter 2, an infrared emission sensor 4 is respectively equipped with in the end face left and right sides of box body 1, infrared receiver sensor 5 is provided with in the end face centre position of box body 1, monitoring distance by-pass cock 6 is provided with in the side of box body 1, monitoring distance by-pass cock 6 is used for regulating head to the monitoring distance of desktop, divide 20cm, 25cm, 30cm tri-shelves, suitable monitoring distance is selected according to the height of child and demand.Power switch 7 is provided with at the opposite side of box body 1, control device is provided with in box body 1, described flicker attention gatter 3, infrared receiver sensor 5, two infrared emission sensors 4, monitoring distance by-pass cockes 6 are connected with control device respectively by wire, and control device is connected with dry cell through power switch 7 by wire.
Described clamping device comprises the horizontally disposed upper buckle 8 be installed on box body 1 back side, box body 1 below upper buckle 8 two ends is provided with two slideways 9 vertically arranged, the two ends of one lower pinch plate 10 be arranged in parallel with upper buckle 8 are placed in two slideways 9 respectively, upper buckle 8 is connected by a bolt 11 with between lower pinch plate 10, upper buckle 8 is provided with a through hole, lower pinch plate 10 is provided with the threaded hole corresponding with through hole, and upper buckle 8 is connected as one with lower pinch plate 10 through through hole and threaded hole by the screw rod of a bolt 11 closed with corresponding threaded holes successively.
