Description
Technical field
This utility model relates to curvature technical field, is specially a kind of curvature testing fixture.
Background technology
Current curvature testing fixture also exists that volume is large, the defect of price and complicated operation, curvature and cornea physiology curvature inconsistent, and error of curvature is large, greatly have impact on judgement and the analysis of observation personnel, and existing curvature testing fixture lighting performance is poor, be unfavorable for the observation that observer is careful, for the judgement and observation of strengthening observation personnel must propose one efficiently, at a low price, curvature testing fixture easily.
Summary of the invention
The purpose of this utility model is to provide a kind of curvature testing fixture, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme: a kind of curvature testing fixture, comprise gripper shoe, observation port, light source and handle, described gripper shoe bottom is fixedly connected with handle, peephole is offered in the middle part of described gripper shoe, described gripper shoe surrounding is installed with light source, and the side of gripper shoe is provided with symmetric flag symmetrical centered by view hole, and light source and centrosymmetry mark are all at the concave surface of gripper shoe.
Preferably, described peephole inside is provided with eyeglass.
Preferably, described handle is provided with skid resistant course.
Preferably, the concavity of described gripper shoe is identical with cornea physiology curvature.
Preferably, described observation port diameter is 6 to 10mm.
Compared with prior art, the beneficial effects of the utility model are: this curvature testing fixture is a kind of hand-held curvature somascope, and observe convenient, simple to operate, diagnosis accurately, the curvature of this instrument conforms to cornea physiology curvature, and the low practicality of cost is wide, is easy to carry.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Fig. 2 is this utility model profile.
In figure: 1 gripper shoe, 2 observation ports, 3 light sources, 4 handles, 5 symmetric flag.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
Refer to Fig. 1, this utility model provides a kind of technical scheme: a kind of curvature testing fixture, comprise gripper shoe 1, observation port 2, light source 3 and handle 4, described gripper shoe 1 bottom is fixedly connected with handle 4, mounting handle 4 can be conducive to user and take, handle 4 is provided with skid resistant course, more be conducive to user to use and not easily landing, peephole 2 is offered in the middle part of gripper shoe 1, observation port 2 diameter is 6 to 10mm, be applicable to the magnitude range of eyeball, peephole 2 inside is provided with eyeglass, observation that can be more careful, gripper shoe 1 surrounding is installed with light source 3, what be conducive to that observer observes under well-lighted condition is very careful, the side of gripper shoe 1 is provided with symmetric flag 5 symmetrical centered by view hole, and light source and centrosymmetry mark 5 are all at the concave surface of gripper shoe, concave surface conforms to cornea physiology curvature, correlation marker 5 is many rays distributed symmetrically and evenly centered by peephole 2, the concavity of gripper shoe 1 is identical with cornea physiology curvature.
Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
