Be tightly connected between described safeguard structure and connecting portion, being tightly connected to be specially is threaded between safeguard structure with connecting portion or is connected by glue between safeguard structure with connecting portion;
Gap is there is between safeguard structure and protected eyeglass.
Above-mentioned safeguard structure periphery is provided with external thread, and connecting portion inwall is provided with the internal thread mated with described external thread.
Above-mentioned safeguard structure and connecting portion are connected by screw.
If safeguard structure is cup-shaped, then the periphery of safeguard structure sidewall opening end is provided with radial extension.
Above-mentioned safeguard structure is provided with relief groove.
The material of above-mentioned safeguard structure is metal or plastics.
The material of above-mentioned safeguard structure is copper or aluminium.
Above-mentioned glue is shellac.
The present invention has following technique effect:
1, by the picture frame of the eyeglass both sides in processed mirror group and trim ring, the present invention is installed, outside fifth wheel both can have been prevented to be bonded in minute surface and to enter in mirror group finedraw and gone, minute surface work in-process also can have been protected from scuffing simultaneously.。
2, version of the present invention is simple, processing and easy for installation, and material of the present invention is copper, aluminium or plastics, and therefore weight is all comparatively light, processes do not have an impact to reality; Later stage dismounting and easy to maintenance.The glue quick-drying selected is molten soon, easy to clean, and screw mounting means is simple, all not easily produces secondary fifth wheel.
3, there is gap between safeguard structure and protected eyeglass, be conducive to keeping suitable distance with minute surface, prevent installation process protective shield to the scuffing of minute surface.
4, picture frame or trim ring inner circle need process the internal thread coordinated with safeguard structure, can be used as eliminate stray light line in optical system, are conducive to veiling glare and suppress.

Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
Each part is processed respectively according to Fig. 1,2,3,4.
The invention provides a kind of mirror finish safeguard structure, safeguard structure is tabular or cup-shaped, and the picture frame of protected eyeglass both sides and trim ring are connecting portion; Be tightly connected between safeguard structure and connecting portion, being tightly connected to be specially is threaded between safeguard structure with connecting portion or is connected by glue between safeguard structure with connecting portion; There is gap between safeguard structure and protected eyeglass, material of the present invention can select lightweight material, such as copper, aluminium or plastics, and safeguard structure is provided with relief groove.
Wherein, a kind of implementation be threaded between safeguard structure with connecting portion is: safeguard structure periphery is provided with external thread, connecting portion inwall is provided with the internal thread mated with described external thread, and another kind of implementation is: safeguard structure and connecting portion are connected by screw.
If safeguard structure is cup-shaped, then the periphery of safeguard structure sidewall opening end is provided with radial extension, and this structure can be used for the mirror group that protected eyeglass protrudes frame structure part end face.
