Specific embodiment
In order to keep the purposes, technical schemes and advantages of the embodiment of the present invention clearer, implement below in conjunction with the present invention
Technical solution in example carries out clear, complete description, it is clear that and described embodiment is section Example of the invention, and
It is not all of embodiment.Based on the embodiment of the present invention, those of ordinary skill in the art are not before making the creative labor
Every other embodiment obtained is put, protection scope of the present invention is belonged to.
As Figure 1-Figure 4, a kind of artificial eye ball, including upper cover 1, lower cover 2, after 2 split of upper cover 1 and lower cover, the two it
Between formed a cavity, further include be arranged on lower cover 2 for into cavity filling stream identical with the crystalline volume density of human eye
The sealing element 3 and sealing screw 4 for sealing in filling aperture is arranged in the filling aperture of body；
The outer surface of upper cover 1 and inner surface are in curved surface, and the radian of curved surface is identical as the pupil radian of human eye；
Wherein, the arc curve coordinate of pupil of human is as follows:
(x1, y1)=(- 6.001, -2.301), (- 5.501, -1.903), (- 5.002, -1.55), (- 4, -0.963),
(- 3.5, -0.731), (- 3, -0.534), (- 2.498, -0.366), (- 2.001, -0.233), (- 1.5, -0.13), (-
1.002, -0.059), (- 0.5, -0.015), (0.5, -0.011), (1.001, -0.051), (1.501, -0.117),
(2.001, -0.212), (2.5, -0.335), (3.002, -0.493), (3.501, -0.686), (4.001, -0.92),
(5.001, -1.518), (5.5, -1.894), (6, -2.337) }；
(x2, y2)=(- 4.502,0.505), (- 4.003,0.348), (- 3.502,0.322), (- 3.002,
0.192), (- 2.503,0.139), (- 2.002,0.107), (- 1.499,0.052), (- 0.999,0.035), (- 0.499,
0.014), (0.5, -0.004), (1,0.007), (1.5,0.027), (2,0.055), (2.5,0.091), (3,0.151),
(3.5,0.21), (3.999,0.291), (4.5,0.431) }；
Above-mentioned coordinate is the through-hole curvilinear coordinate of true eyeball, according to the coordinate points formation curve that measurement obtains, and
Eyeball phantom is simulated in three-dimensional software, and makes mold, for producing upper cover 1 and lower cover 2, is produced according to the curvilinear coordinate
Upper cover 1 have the curved surface of true eyeball, it is more close with the optical effect of true eyeball；
Filling aperture is divided into different two sections of diameter, and one section of more another section of diameter of close cavity carefully, makes filling aperture
Whole is in step-like；
Sealing element 3 is less than normal compared with the major diameter of filling aperture in coniform and its basal diameter, and vertex one end of sealing element 3 is stretched
Enter the path part to filling aperture, and forms gap between bottom surface one end of sealing element 3 and the step part of filling aperture；Seal spiral shell
For nail 4 when tightening, the bottom surface end thereof contacts of end and sealing element 3 simultaneously compress sealing element 3；
It is false since the volume of cone is same bottom surface and with the one third of high cylindrical body since sealing element 3 is in cone
If sealing element 3 be inserted into filling aperture path part length be equal to path part length, then fluid filling into cavity when
It waits, the liquid level of fluid needs 2/3rds more than filling aperture path Partial Height, it can be understood as, when canned fluid
Later, sealing element 3 is filled in, can guarantee that cavity is closed and internal without air, it, also can be from if fluid has excess
It overflows and flows into the gap between sealing element 3 and filling aperture in the side of sealing element 3.
Sealing element 3 divides for two parts, for blocking the hard portion at filling aperture path position and contacting with 4 end of sealing screw
Soft part.
In the present embodiment, unlike a upper embodiment, sealing element 3 divides for hard portion and soft part, and hard portion is stifled
Firmly it is difficult that deformation occurs when filling aperture path position, therefore can firmly stopper sealing element 3 will not lead to fluid in cavity
Density changes, and the soft part contacted with sealing screw 4 is under the extruding of sealing screw 4 that deformation occurs, make itself than filling
The bottom surface of the smaller sealing element 3 in dress hole aperture expands outwardly, and is bonded with the inner wall of filling aperture, makes the stream being previously flowed into gap
Body will not expose.
As shown in figure 5, being spliced between upper cover 1 and lower cover 2 by the buckle of elastic self-locking type simultaneously refering to Fig. 3；
Buckle includes the upper buckle 5 being arranged in upper cover 1 and the lower buckle 6 being arranged on lower cover 2, upper to buckle on 5；
In the present embodiment, the splitting mode of upper cover 1 and lower cover 2 uses the self-locking buckle of elasticity, has easy for installation
Quick feature, is able to ascend the efficiency of production, and increases the stability of structure.
The contact site of upper cover 1 and lower cover 2 is coated with biocompatibility UV glue, after being irradiated by UV light, upper cover 1 and lower cover
2 realize fixed and sealing.
After upper cover 1 and lower cover 2 assemble, UV adhesive curing is carried out in the outer surface connection of artificial eye ball, further
Junction is sealed and is fixed, loosening or leakage are prevented.
For upper buckle 5 in hook-shaped, there is the protrusion 51 towards cavity opposite direction in end, is provided on raised 51 top surface close
Seal 52；
The shape of lower buckle 6 is complementary with upper buckle 5, the position setting fluted 61 of respective protrusions 51, lower card on lower buckle 6
Gum box 62 is additionally provided on button 6；
Wherein, the position that gum box 62 is arranged is at the maximum horizontal plane of contact surface of lower buckle 6 and upper buckle 5, preferably
Ground is the top surface of lower buckle 6, and upper buckle 5 and lower buckle 6 first add glue into gum box 62 before engaging.
After upper buckle 5 and 6 splits of lower buckle, the outer surface of artificial eye ball and inner surface are smooth.
The cross section of protrusion 51 is trapezoidal, and sealing ring 52 is arranged on trapezoidal top margin；
In the present embodiment, during installation, inclined-plane can help buckle 5 to snap onto the trapezoidal protrusion 51 in cross section
In lower buckle 6, and utilize the elasticity of itself and lower 6 fastening of buckle.
As shown in fig. 6, being provided with the through-hole 41 through entire screw on sealing screw 4, wherein the effect of through-hole 41 be
When tightening sealing screw 4, the air in filling aperture is discharged, if air cannot be discharged, or only using between screw thread
Gap is exhausted, and the air pressure that may exist in the unsmooth caused filling aperture of exhaust is excessively high, moves sealing element 3 into cavity,
The density of the fluid in cavity is caused to change.
Present invention employs the curves for simulating true eye through-hole, and filling is close with crystalline lens in the cavity being made of upper and lower covers
Identical fluid is spent, it is whole very close with the optical effect of true eyeball, make the Function detection result of eyeground photographing device more
To be accurate, meanwhile, using the structure of the self-locking buckle of elasticity and the sealing element 3 of taper and the sealing screw 4 with through-hole, altogether
With ensure that the density stabilized of artificial eye ball internal flow, to guarantee that its optical effect is stablized, the accuracy that eyeground is taken pictures is promoted.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
