Initially, the front side of the vertical plate 4 is pasted with color blindness cards of different colors circumferentially, firstly, an operator steps on the driving mechanism 7 to operate, the driving mechanism 7 operates to drive the rotating shaft 5 to rotate, the rotating shaft 5 rotates to drive the notch plate 6 to rotate, when the driving mechanism 7 steps to a proper time, the driving mechanism 7 stops stepping, the notch plate 6 continuously rotates, the operator further pushes the movable block 11 to move leftwards, the second spring 10 compresses, the movable block 11 moves leftwards to drive the arc plate 9 to move leftwards, the arc plate 9 moves leftwards to contact with the notch plate 6 to fix the same, the notch plate 6 stops rotating, meanwhile, the movable block 11 moves leftwards to separate from the limiting mechanism 12, the limiting mechanism 12 operates to fix the movable block 11, the limiting mechanism 12 also limits the driving mechanism 7, at this time, the operator can see the color blindness cards on the vertical plate 4 to speak out the seen color blindness cards through the notch plate 6, medical personnel then take notes the colour that operating personnel said, pull stop gear 12 operation again and reset, and stop gear 12 is not spacing with actuating mechanism 7, because of the effect of second spring 10, and movable block 11 drives arc 9 and moves right and reset, and movable block 11 then contacts with stop gear 12, according to above-mentioned operation, and operating personnel can step on actuating mechanism 7 once more and operate, sees the achromatopsia card and says out through breach board 6 once more. When the operator watches the required times of the color blindness card, the operator stops stepping on the driving mechanism 7, and the medical personnel can judge whether the operator has color blindness according to the record.
Firstly, an operator steps on the pedal 704 to move downwards, the pedal 704 moves downwards to drive the rack 702 to move downwards, the first spring 703 is compressed, the rack 702 moves downwards to drive the gear 707 to rotate forwards, the gear 707 rotates forwards to drive the one-way shaft 706 to rotate forwards, the one-way shaft 706 rotates forwards to drive the transmission assembly 708 to rotate forwards, the transmission assembly 708 rotates forwards to drive the rotating shaft 5 to rotate forwards, the rotating shaft 5 rotates forwards to drive the notch plate 6 to rotate forwards, then the pedal 704 is released, the rack 702 moves upwards to drive the gear 707 to rotate backwards under the action of the first spring 703, the gear 707 rotates backwards to drive the one-way shaft 706 to rotate backwards, the one-way shaft 706 rotates backwards without driving the transmission assembly 708 to rotate backwards, the pedal 704 is repeatedly and continuously stepped on, the notch plate 6 can continuously rotate forwards, when the pedal 704 is stepped on for a proper time, the pedal 704 stops being stepped on, the movable block 11 is pushed to drive the arc-shaped plate 9 to move, the healthcare worker then records the spoken color. Thus, the notch plate 6 can be stopped on the color blindness card at random.
Initially, third spring 1203 is tensile state, when operating personnel promoted the movable block 11 and drives arc 9 and move left and fix breach plate 6, movable block 11 breaks away from with contact bar 1205, because of the effect of third spring 1203, slide bar 1202 moves forward and drives backup pad 1204 and move forward, backup pad 1204 moves forward and drives contact bar 1205 and moves forward, contact bar 1205 moves forward and blocks movable block 11, operating personnel can loosen movable block 11, and simultaneously, backup pad 1204 still drives limiting plate 1206 and moves forward, limiting plate 1206 moves forward and carries out spacingly to it below footboard 704, operating personnel then steps on unmovable footboard 704, can begin to look over the colour of achromatism card. After the color of the color blindness card is checked, the sliding rod 1202 is pulled to move backwards, the third spring 1203 is stretched, the sliding rod 1202 moves backwards to drive the contact rod 1205 to move backwards and reset with the limiting plate 1206 through the supporting plate 1204, the contact rod 1205 resets and does not block the movable block 11, the movable block 11 moves rightwards to reset and blocks the contact rod 1205, the sliding rod 1202 is loosened, and meanwhile, the limiting plate 1206 resets and does not block the pedal 704.
Example 2
Referring to fig. 1, fig. 2 and fig. 3, the present embodiment is different from embodiment 1 mainly in that in the present embodiment, the present embodiment further includes an L-shaped plate 13, a first rotating rod 14, a second rotating rod 15, a sprocket 16, a chain 17, a mounting plate 18 and an indicating plate 19, the L-shaped plate 13 is fixedly connected to the lower portion of the rear side of the support plate 2, the first rotating rod 14 is rotatably connected to the right portion of the outer rear side of the L-shaped plate 13, the second rotating rod 15 is fixedly connected to the rear end of the rotating shaft 5, the sprocket 16 is fixedly connected to both the rear end of the second rotating rod 15 and the rear end of the first rotating rod 14, the chain 17 is wound between the upper and lower side sprockets 16, the mounting plates 18 are fixedly connected to the rear side of the chain 17 at uniform intervals in the circumferential direction, the indicating plate 19 is fixedly connected to the lower portion of the rear.
Firstly, the medical staff pastes the achromatopsia card on the rear side face of the mounting plate 18, when the transmission component 708 rotates positively, the transmission component 708 also drives the second rotating rod 15 to rotate positively, the second rotating rod 15 rotates positively to drive the upper chain wheel 16 to rotate positively, the upper chain wheel 16 rotates positively to drive the chain 17 to rotate positively through the lower chain wheel 16, the chain 17 rotates positively to drive the mounting plate 18 to rotate positively, the mounting plate 18 rotates positively to drive the achromatopsia card to rotate positively, when the arc-shaped plate 9 fixes the notch plate 6, the transmission component 708 stops rotating positively, the chain 17 also stops driving the mounting plate 18 to rotate positively, the operating staff can check the achromatopsia card on the mounting plate 18 pointed by the indicating plate 19, then the seen color is spoken, and the medical. Therefore, the accuracy of the color blindness test can be improved.
Referring to fig. 1, the device further includes a rocker 20, and the rocker 20 is fixed to the front side of the notch plate 6 at an eccentric position.
When the notch plate 6 stops rotating forwards and the notch of the notch plate 6 rotates to a position between two color blindness cards, an operator can pull the rocker 20 to rotate, the rocker 20 rotates to drive the notch plate 6 to rotate, and the notch plate 6 stops pulling the rocker 20 to rotate when the notch plate 6 rotates to see one complete color blindness card. Therefore, the phenomenon that the view of the color is influenced by the fact that the gap of the gap plate 6 is over against the two color blindness cards is avoided.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
