The purpose of this utility model is achieved through the following technical solutions:
A kind of survey vision is assisted radical occlusion device, comprises U-shaped, described U-shaped by crossbeam and earpiece two parts of being located at respectively crossbeam two ends form, described crossbeam is provided with bridge of the nose hanging seat in the side projection with the earpiece equidirectional; Described crossbeam lower end is provided with left eye-shading plate and right eye-shading plate side by side, and described left eye-shading plate and right eye-shading plate are connected in respectively the lower end of crossbeam by rotating member.
In order to realize better this utility model, described two earpieces respectively with crossbeam to be connected the end hinged, like this, two earpieces can be taken in very easily and fold into the crossbeam sidepiece; During use, launch two earpieces and be hung on two ears of human body and get final product.
It is that described rotating member is the deformable flexible contiguous block that this utility model provides a kind of preferred rotating member technical scheme.This flexibly connects distortion plastic cement or distortion rubber that piece can be selected flexible freely deformable, can certainly be spring, can certainly be other material or structure that can realize turning down up and down distortion.
Technical scheme further is, be equipped with catch on described left eye-shading plate and right eye-shading plate, this catch has facilitated people overturn left eye-shading plate or right eye-shading plate, during upset, only need to stir up and down this catch, this catch can drive left eye-shading plate or right eye-shading plate stirs up and down, thereby realizes the purpose that testee's left eye or right eye are blocked in selection.
This utility model is compared than prior art, has the following advantages and beneficial effect:
(1) crossbeam of the present utility model two ends are equipped with earpiece, and the crossbeam middle part is provided with bridge of the nose hanging seat, can be convenient for people to this radical occlusion device is hung on human face.The lower end of crossbeam is provided with the left eye-shading plate that can block left eye and the right eye-shading plate that can block right eye side by side, and when needs detected separately left eye or right vision, only need to rotate to an angle corresponding eye-shading plate got final product.It is time saving and energy saving to operate, and greatly facilitates the medical worker and detects patient's vision, has improved ophthalmology examination of visual acuity efficient.When not using, can two earpiece folding storages are inboard, very easy to use to crossbeam.
(2) the left eye-shading plate of this radical occlusion device be connected eye-shading plate and be connected with the crossbeam lower end by rotating member respectively, make rotary manipulation more laborsaving, and be equipped with the catch that is convenient for people to spin upside down on left eye-shading plate and right eye-shading plate, so just make people operate more convenient.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of this utility model after the right eye-shading plate of rotation.
Wherein, the corresponding name of the Reference numeral in accompanying drawing is called:
1-U type frame, 2-bridge of the nose hanging seat, the left eye-shading plate of 3-, the right eye-shading plate of 4-, 5-rotating member, 6-catch, 11-crossbeam, 12-earpiece.
The specific embodiment
Below in conjunction with embodiment, this utility model is described in further detail:
Embodiment
As Fig. 1～shown in Figure 2, a kind of survey vision is assisted radical occlusion device, comprises U-shaped 1, and U-shaped 1 of the present utility model is comprised of crossbeam 11 and earpiece 12 two parts of being located at respectively crossbeam 11 two ends.Crossbeam 11 is provided with bridge of the nose hanging seat 2 in the side projection with earpiece 12 equidirectionals, and this bridge of the nose hanging seat 2 includes the bridge of the nose Support bracket of reverse V-shaped shape, is convenient for people to and this radical occlusion device can be worn in human face.
See also Fig. 1, the lower end of crossbeam 11 is provided with left eye-shading plate 3 and right eye-shading plate 4 side by side, and left eye-shading plate 3 is connected in respectively the lower end of crossbeam 11 with right eye-shading plate 4 by rotating member 5.
As shown in Figure 1, two earpieces 12 respectively with crossbeam 11 to be connected the end hinged.Like this, two earpieces 12 can be taken in very easily and fold into crossbeam 11 inboards.When needs use, launch two earpieces 12 and be hung on two ears of human body and get final product.Not only easy to use, and be convenient to folding storage.
. rotating member 5 of the present utility model is the deformable flexible contiguous block.This flexibly connects distortion plastic cement or distortion rubber that piece can be selected flexibility and freely deformable, can certainly be spring, and this rotating member 5 can be also other material or structure that can realize turning down up and down distortion certainly.
