A kind of intraocular lens' spectral transmittance test fixture provided, reduces the measurement difficulty of intraocular lens' spectral transmittance,
And measurement effect is greatly improved, process is simplified, improves working efficiency.
Utility model content
The purpose of the utility model is to provide a kind of intraocular lens' spectral transmittance test fixtures, reduce intraocular implants
The measurement difficulty of body spectral transmittance, and measurement effect is greatly improved, simplify process, improves working efficiency.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of intraocular lens' spectral transmittance is surveyed
Trial work fills, including pedestal, and vertical through-hole is equipped at the center of the pedestal, and the outer ring of the through-hole is equipped with positioning column；It is described
It is equipped with spacer ring above pedestal, the spacer ring housing is placed with protection cap, and the center of the protection cap is equipped with through hole, under the pedestal
End four corners are equipped with connecting pin, and the connecting pin is equipped with a circle groove, and the connecting pin is equipped with sucker ontology, the suction
Disk ontology includes rubber suction cups, and the top of the rubber suction cups is equipped with connector sleeve, and the connector sleeve is equipped with a circle and is recessed inwardly
Retainer ring.
Preferably, the rubber suction cups is an integral structure with connector sleeve, and the connector sleeve is rubber material, the connection
It holds in force fit connector sleeve.
Preferably, there is the fillet of screw in the protection cap inner ring, the spacer ring outer layer is equipped with the fillet of screw.
Preferably, the positioning column is 3 or 4, and each positioning column is identical at a distance from through-hole.
Preferably, the through hole at the center of the protection cap is same diameter as through hole and upper and lower corresponding.
The beneficial effects of the utility model are: the device reduces the measurement difficulty of intraocular lens' spectral transmittance, and
And measurement effect is greatly improved, and simplify process, improves working efficiency, in addition sucker ontology may be implemented individually to replace,
Improve the service life of integrated tooling.

In figure: 1, spacer ring, 2, pedestal, 3, through-hole, 4, positioning column, 5, connecting pin, 51, groove, 6, sucker ontology, 61, rubber
Glue sucker, 62, connector sleeve, 63, retainer ring, 7, protection cap, 71, through hole.
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 describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all
Embodiment, based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment
A kind of intraocular lens' spectral transmittance test fixture, including pedestal 2 are equipped at the center of pedestal 2 vertical logical
The outer ring in hole 3, through-hole 3 is equipped with positioning column 4；Spacer ring 1 is equipped with above pedestal 2,1 housing of spacer ring is placed with protection cap 7, protection cap 7
Center is equipped with through hole 71, and 2 lower end four corners of pedestal are equipped with connecting pin 5, and connecting pin 5 is equipped with a circle groove 51, connecting pin 5
It is equipped with sucker ontology 6, sucker ontology 6 includes rubber suction cups 61, and the top of rubber suction cups 61 is equipped with connector sleeve 62, connector sleeve 62
It is equipped with the retainer ring 63 that a circle is recessed inwardly.
Wherein, rubber suction cups 61 is an integral structure with connector sleeve 62, and connector sleeve 62 is rubber material, 5 interference of connecting pin
It is pressed into connector sleeve 62.
Wherein, there is the fillet of screw in 7 inner ring of protection cap, 1 outer layer of spacer ring is equipped with the fillet of screw.
Wherein, positioning column 4 is 3 or 4, and each positioning column 4 is identical at a distance from through-hole 3.
Wherein, the through hole 71 at the center of protection cap 7 is identical as the diameter of through-hole 3 and upper and lower corresponding.
Intraocular lens' card is put at through-hole 3 by concrete operating principle, so that the connection button loop set of intraocular lens is put in and determines
On the column 4 of position, then protection cap 7 is anchored on outside spacer ring 1, the tooling is then fixed on photometer using rubber suction cups 61 and is detected
In the light passing outer wall of hole of device, so that the center of circle of through-hole 3, the center of circle of through hole 71 and light hole is point-blank, entire mistake
Journey is convenient, fast, reduces the measurement difficulty of intraocular lens' spectral transmittance, and greatly improves measurement effect, letter
Change process improves working efficiency,
Connecting pin 5 and connector sleeve 62 are interference fit, and sucker ontology 6 can be disassembled from pedestal 2, and sucker may be implemented
Ontology 6 is individually replaced, because the service life of rubber material is relatively short, local replacement can extend making for integrated tooling
Use the service life.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent character made based on the specification and figures of the utility model or Structural Transformation, are applied directly or indirectly in other
Relevant technical field, is also included in the patent protection scope of the utility model.
