Description
Technical field
The utility model relates to a kind of eye examination auxiliary tools, check particularly directed to the eye position of children, also can be used
It in ophthalmology near vision, adjusts, near point of convergence, the Multifunctional round hole shape cassette for melting the functional checks such as picture adjusts sighting target ruler.
Background technique
Currently, in eye examination, in strabismus property and substantial degree of inspection, we commonly use a lamp or adjust view table
(such as some animals graphics) check eye position.During the inspection process, if looked into a lamp inspection, there is corneal reflection, inspection is sentenced
The property and basic degree of disconnected strabismus are more accurate, but because looking at light straight, bigger to the stimulation of eyes, patient is uncomfortable,
When especially children check, much mismatches and can not check；When with adjusting sighting target inspection, the not stimulation of light, patient's sense
Feel more comfortable, but there is no corneal reflection, it is just very inaccurate to the substantial degree of judgement of strabismus.Because the invention one kind can be with
Clear reflective spot is checked with a lamp inspection, and does not stimulate the adjusting sighting target ruler that can be stuck in above a lamp of eyes very useful.
Utility model content
The purpose of this utility model provides a kind of Multifunctional round hole shape cassette adjusting view aiming at the defect of existing tool
Scale, to make up the deficiency of existing tool.
To achieve the above object, the utility model provides the following technical solutions:
Multifunctional round hole shape cassette adjusts sighting target ruler, including sighting target ruler, circle hole shape card slot and round shaft, the sighting target ruler
It can be single children and adjust the short ruler of sighting target and the long ruler of ribs of the fan formula folding multi-functional sighting target；The centre of the circle hole shape card slot is equipped with
Elastic rubber circle；It is caught in three pieces sighting target ruler in the circle hole shape card slot, there are gap among the three pieces sighting target ruler, avoids revolving
Fretting wear sighting target figure in turning；The upper end that the three pieces sighting target ruler is located in the middle the short ruler of sighting target has more a section sighting target ruler, point
The upper and lower ends of round shaft are occupied, draw single adjusting sighting target figure thereon；The three pieces sighting target ruler divides tow sides.
Preferably, the long 150mm of sighting target ruler, wide 20mm.
Preferably, the diameter of the elastic rubber circle is 11mm.
Preferably, the long 20mm of the short ruler of the sighting target, the long ruler 5 of sighting target are 105mm long.
Preferably, the sighting target can be adjust cross sighting target, nearly cross grid sighting target, 3 points melt as sighting target, concentric circles are red
It is green to melt as sighting target, eyesight detection card and 10cm scale sighting target.
Compared with prior art, the utility model has the beneficial effects that
The view scale structure that the utility model provides is simple, easy to use, can see that again in the case where not stimulating eyes anti-
Luminous point.It can be not only used for the inspection of eye position, because its other three pieces sighting target ruler can draw a variety of inspection sighting targets, for as adjusted
It saves, gather, melting the common inspection of the ophthalmology such as picture and near vision.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2-4 is the sighting target design drawing group of the utility model.
In figure: 1, the short ruler of sighting target, 2, elastic rubber circle, 3, circle hole shape card slot, 4, round shaft, 5, the long ruler of sighting target, 6, tune
Save sighting target, 7, adjust cross sighting target, 8, nearly cross grid sighting target, 9,3 points melt as sighting target, 10, concentric circles it is red it is green melt as sighting target,
11, eyesight detection card, 12,10cm graduated scale.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
1 Multifunctional round hole shape cassette of embodiment adjusts sighting target ruler, and structure is as shown in Figs 1-4, including sighting target ruler, circle hole shape
Card slot 3 and round shaft 4, the sighting target ruler can be single children and adjust the short ruler 1 of sighting target and ribs of the fan formula folding multi-functional sighting target
Long ruler 5；The centre of the circle hole shape card slot 3 is equipped with elastic rubber circle 2；Three pieces sighting target ruler, institute are caught in the circle hole shape card slot 3
It states among three pieces sighting target ruler there are gap, avoids the fretting wear sighting target figure in rotation；The three pieces sighting target ruler is located at centre
The upper end of the short ruler of sighting target have more a section sighting target ruler, the upper and lower ends for shaft of living apart draw single adjust sighting target figure thereon；Institute
It states three pieces sighting target ruler and divides tow sides.The short ruler 1 of sighting target is wherein individually adjusted to hang down respectively with the long ruler 5 of ribs of the fan formula folding multi-functional sighting target
The straight upper and lower ends for being located at round shaft 4, the long ruler 5 of ribs of the fan formula folding multi-functional sighting target of lower end can be used as hand holding handle.
In above-described embodiment, specifically, the long 150mm of sighting target ruler, wide 20mm.
