The vision testing box comprises a top frame, a rack, a supporting plate, a rotating handle, a pin shaft, a gear, a base and two stop sheets, wherein the top frame comprises a V-shaped plate and two strip-shaped plates, the rack is a rectangular plate, the two stop sheets are installed on the top of the supporting plate, the gear and the rotating handle are fixedly installed on two lateral sides, close to the top end, of the supporting plate through the pin shaft, the lower ends of the two strip-shaped plates are vertically and fixedly installed at the two ends of the V-shaped plate respectively, the two strip-shaped plates are fixed to the two side walls of a vision testing box body respectively, the bottom end of the V-shaped plate is fixedly connected with the top end of the rack, and the bottom end of the supporting plate is arranged on the base. The vision testing box is applied to vision testing for children.
Description
Technical field
This utility model relates to a kind of vision case with adjustable support.
Background technology
Vision case is the instrument for measuring vision, vision case is to formulate according to the principle at visual angle, correct operational approach is that a line of 1.0 of sight line and vision case of detected person is concordant, detected person is apart from 5 meters of the distances of vision case, but vision case of the prior art is fixed on a fixing position conventionally, in the time that measured is child, because child's different detected person's the sight lines that make of height can not be concordant with a line of 1.0 of vision case, cause measuring and have error, can not accurately detect detected person's vision, and in the time that need to moving replacing working environment, vision case must be placed on body of wall or other framework, define the use of vision case.
Utility model content
This utility model is in order to solve vision case of the prior art in the time that detected person is child, because height different sight can not be concordant with a line of vision case 1.0, cause measuring inaccurate, and the problem that is restricted of the working environment of vision case, and then provide a kind of vision case with adjustable support.
This utility model is to address the above problem the technical scheme adopting to be: it comprises top frame, tooth bar, support plate, turning handle, bearing pin, gear, base and two catch, top frame comprises ' V ' shape plate and two strip plates, tooth bar is rectangular slab, a side of tooth bar is vertically processed with rectangle boss, a side of support plate is vertically processed with bar-shaped trough, the top of support plate is provided with two catch, and two catch and bar-shaped trough are positioned on the same side of support plate, gear and turning handle are fixedly mounted on two sides near support plate top by bearing pin, the lower end of two strip plates is vertically fixedly mounted on respectively the two ends of ' V ' shape plate, two strip plates are separately fixed on two sidewalls of vision case, the bottom of ' V ' shape plate is fixedly connected with the top of tooth bar, the rectangle boss of tooth bar is arranged in the bar-shaped trough of support plate, and the tooth of tooth bar engages with gear, the bottom of support plate is arranged on base.
The beneficial effects of the utility model are: the vision case by the present invention with adjustable support, the height of adjusting gear rack 5 and gear 14 and then adjusting vision case 1, the sight line that can guarantee measured is concordant with a line of vision case 1.0, and the distance that simultaneously guarantees measured and vision case guarantees the distance for 5m, working environment by all right vision case of the present invention is unrestricted, this utility model also has simple in structure, easy to use, advantage reasonable in design.
