Description
Technical Field
The utility model belongs to a device for eyesight detects.
Background
People pay attention to the health of eyesight at present, detect the visual chart lamp house of bore hole eyesight on the market and all adopt external power source direct power supply, and whole E word visual chart panel is all lighted by the fluorescent tube in the lamp house, and the inspection personnel hand is looked the mark, and these all can cause to require highly to the detection ring border, and the operation is inconvenient, problem that work efficiency is low, the quick and the accuracy of direct influence detection.
Disclosure of Invention
The utility model provides a visual chart lamp house to the testing environment who solves current visual chart existence requires highly, needs the inspection personnel to go up visual target point-to-point finger operation on the visual chart, and intensity of labour is big, problem that work efficiency is low.
The technical scheme of the utility model is that: the rear part of the aluminum alloy surface frame is fixedly connected with the aluminum alloy box body, the lamp groove is fixedly connected with the inside of the aluminum alloy surface frame, the E-shaped visual chart panel is inserted into the lamp groove and fixedly connected with the aluminum alloy surface frame, the LED lamp strip groups and the lamp groove partition plates are respectively embedded in the lamp groove, the lamp groove partition plates separate the LED lamp strip groups according to the E-shaped positions of each row on the E-shaped visual chart panel, the circuit board is fixedly connected with the back of the lamp groove, the rechargeable lithium battery and the voltage stabilizing module are respectively connected with the circuit board, the power switch and the power socket are respectively fixedly connected with the side surface of the aluminum alloy box body, and the power switch, the power socket and the LED lamp strip groups are respectively electrically connected with the circuit board.
The utility model has the advantages that: novel structure through lithium cell power supply to light, supply the surveyed personnel to read through bluetooth wireless control E word sighting mark single file, easy operation, convenient and fast adapts to various screening environments, convenient to carry does not need the survey crew to the sighting mark point finger operation on the visual chart, has improved visual examination's efficiency, reduces intensity of labour.
