Abstract
The utility model relates to a visual acuity chart lamp for testing eyesight. On the original structure of the existing ordinary visual acuity chart lamp for testing eyesight, a red indicating lamp and a green indicating lamp are arranged. The indicating lamps are driven by two miniature motors to shift through a driving device; the rotation directions of the two miniature motors are controlled by four relays and a switch so that the indicating lamps move in the upper direction, the lower direction, the left direction and the right direction to indicate the region which needs to be tested. One of the two indicating lamps can emit light to detect the red-green blindness under the control of a converting switch.
Description
This utility model relates to a kind of ophthalmologic examination vision and red, deuteranopic Visual chart lamp box for testing eyesight of being specifically designed to.
In the prior art, when testing eyesight, the medical worker needs to finish with the different parts on the indication visual acuity charts such as waddy, and especially when colony's health check-up, to the tested position of indication that each examinee wants repeated multiple times, labor intensity is very big.Its weak point also shows: existing common visual acuity chart can not be used for checking achromatopsia.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of medical worker's labor intensity that can alleviate is provided, and can also check red, the deuteranopic Visual chart lamp box for testing eyesight of patient simultaneously.
The purpose of this utility model reaches by following measure: on the original structure of existing common Visual chart lamp box for testing eyesight, two display lamps are installed, and one red, one green.This display lamp moves under the drive of two micromotors by actuating device, and the rotation direction of two motor is controlled by four relays and a switch, make display lamp can be up and down, left and right any direction moves, and indicates the position of required detection.
The purpose of this utility model is achieved in that also red, green two display lamps under the control of a permutator, make one of them luminous,, deuteranopsia red in order to check.
This utility model has following advantage compared to existing technology: 1, replaced the indication action of human waddy etc. by the motor drives display lamp, alleviated medical workers, especially its advantage is more outstanding when colony's health check-up.2, because pilot bulb is one red one green, when testing eyesight, can also check patient's anerythrochloropsia.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is this utility model running part structural representation.
Fig. 2 is a circuit installation diagram of the present utility model.
With reference to Fig. 1, fixed support (1), (2) are fixed on the shell of Visual chart lamp box for testing eyesight, when motor (5) rotates, under the drive of driving-belt (6), rotate simultaneously wheel (7), (8), (9) be fixed on the axle (3), under the drive of driving-belt (10), (11), the cross bar (12) that (10), (11) are fixed in two ends moves up or down thereupon.When motor (13) rotated, the pilot bulb (15) that under the drive of driving-belt (14), is fixed on (14) can left or move right.
With reference to Fig. 2, S1, S2 are two illuminating daylight lamp, and S3, S4 are two indication lamps, and one red one is green, and C1, C2 and C3, four relays of C4 are controlled the rotation direction of two motor respectively.
Claims (3)
1, a kind of Visual chart lamp box for testing eyesight, it is characterized in that: on the original structure of existing common Visual chart lamp box for testing eyesight, two display lamps are installed, one red one is green, this lamp moves under the drive of two micromotors by actuating device, the rotation direction of two motors makes display lamp can do moving of upper and lower, left and right any direction by four relays and an on-off control, indicates required detection position.
2, according to the described Visual chart lamp box for testing eyesight of claim 1, it is characterized in that:, make two motor do the rotation of different directions respectively with four relays of a crossbar switch control.
