Abstract
The utility model relates to an instrument mainly for vision test and training, specifically to a flip mirror with a timing unit and a counting unit, solving the problem in timing and counting when a doctor tests the eye adjusting flexibility. The flip mirror comprises a flipper body, a step motor, a step motor controller, a flat plate and a motor rack. The flip mirror also comprises a gang switch, a timer, a buzzer, a photoelectric encoder, a counter and a liquid crystal screen. One control signal output terminal of the gang switch is connected with the control signal input terminal of the step motor controller, and the other control signal output terminal of the gang switch is connected with the control signal input terminal of the timer. The signal output terminal of the timer is connected with the signal input terminal of the buzzer. The photoelectric encoder is disposed at a long pole of the flipper body to collect a rotation number signal. The signal input terminal of the counter is connected with the signal output terminal of the photoelectric encoder, and the signal output terminal of the counter is connected with the signal input terminal of the liquid crystal screen.
Description
Technical field
This utility model relates to the instrument of a kind of visual inspection and training.Be mainly used in the visual exercise and the inspection of an optometry.
Background technology
(Flipper) clapped in upset is that the inspection eyes are regulated flexibility ratio and gathered the optometry apparatus that looses flexibility ratio and be used for visual exercise.When using, see through upset and clap the nearly Flipper that overturns after with the word on the visual acuity chart that is seeing certain distance clearly.The patient uses the identical flippers eyeglass of the positive and negative mirror number of degrees, sees upset Double sided mirror at the moment behind the sighting target on the test-card clearly, and overturn 1 telescope direct and 1 negative mirror are 1 cycle.When the adjusting flexibility ratio that the doctor carries out eyes is measured, need control Measuring Time, and will write down the periodicity of upset Double sided mirror in 1 minute of measuring and adjusting flexibility ratio simultaneously with stopwatch.Because environmental limit, the doctor often can not carry timing tool, and the clinical position that is separated into of timing tool and Double sided mirror has caused inconvenience and reduced work efficiency.In addition, the doctor not only wants also will write down periodicity simultaneously writing time, in the actual measurement process, does not write down the instrument of periodicity, and the doctor can only accomplish counting work with oral counting form.Like this, the doctor usually can not accurately take the time, and the periodicity of record is also not accurate enough.
Summary of the invention
The purpose of this utility model provides a kind of upset mirror with time-counting device, the problem of timing and counting when carrying out the adjusting flexibility ratio measurement of eyes with the solution doctor.It comprises upset bat body 1, motor 2, controllor for step-by-step motor 3, flat board 6 and electric machine support 7; The lower end of electric machine support 7 is fixed on the upper surface of flat board 6; Motor 2 is fixed on the top of electric machine support 7; The stock end of upset bat body 1 links and the coaxial rotation of ability with the motor shaft of motor 2; The control signal output ends of controllor for step-by-step motor 3 is connected the controlled end of motor 2 through lead; It also comprises gang switch 11, timer 12, buzzer 13, photoelectric encoder 15, enumerator 16 and liquid crystal display screen 17, and a control signal output ends of gang switch 11 connects the control signal input of controllor for step-by-step motor 3, the control signal input of another control signal output ends connection timer 12 of gang switch 11; The signal output part of timer 12 connects the signal input part of buzzer 13; Photoelectric encoder 15 is arranged on the stock of upset bat body 1 and sentences collection revolution signal, and the signal output part of photoelectric encoder 15 is connected the signal input part of enumerator 16, and the signal output part of enumerator 16 connects the signal input part of liquid crystal display screen 17.
This utility model in use, visual acuity chart is placed on the front side that body 1 is clapped in upset, the people claps the rear side of body 1 and claps the symbol on the eyeglass identification visual acuity chart on the body 1 through upset in upset.After identification is clear, press gang switch 11, make the pulse signal of controllor for step-by-step motor 3 output regular lengths, thereby make the motor shaft of motor 2 rotate 180 degree, make upset clap body 1 and accomplished 180 degree upsets.One 360 degree of every upset sends a count pulse for enumerator 16 through photoelectric encoder 15, and enumerator 16 carries out counting work, and can show through liquid crystal display screen 17.When for the first time pressing gang switch 11, enumerator 16 also is activated, and timing stops automatically after 1 minute, and sends caution sound, points out that time is up in 1 minute.The numeral that at this time directly reads from liquid crystal display screen is the periodicity of upset mirror upset, is this patient's adjusting flexibility ratio.This utility model has solved the doctor and has regulated the problem that is difficult to simultaneously accurate timing and counting when flexibility ratio is checked.Can automanual writing time and periodicity during the measuring and adjusting flexibility ratio, can reduce working doctor intensity, and make check result more accurate, improve the true effect of diagnostic accuracy and reflection training.This utility model is practical, has simplified doctor measuring greatly and has regulated the measuring process of motility, and improved the accuracy and the efficient of this inspection, has alleviated doctor's labor intensity.
