On frame, the head end of field lens frame is fixed with field lens.
Further, the head end outer wall of described graduation sheet frame arranging detent, the tail end of described field lens frame is enclosed within location
Outside groove.
Further, described lens barrel is provided with first screw pilot hole corresponding with described first screw, described field lens frame
The second screw pilot hole that upper setting is corresponding with described second screw.
Further, described lens barrel, described graduation sheet frame, described graticle, described field lens frame and the centrage of described field lens
Overlap.
The beneficial effects of the utility model:
1, this utility model devises graduation sheet frame and field lens frame so that graticle and field lens are separated into two parts, it
After graticle is fixed on the head end of graduation sheet frame, field lens is fixed on the head end of field lens frame, and field lens frame is fixed on graduation
On sheet frame, occur doing over again or client returns the situation of maintenance if follow-up, only the first screw and the second screw need to be unclamped,
Convenient disassembly, it is simple to maintenance.
2, in the case of ensureing that optical system is constant, lens barrel is designed with the first screw pilot hole, at graduation sheet frame
On be designed with detent, location is simple, can be fixed by all parts by the first screw and the second screw, side simple to operate
Just.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
