Detailed description of the invention
Below in conjunction with Figure of description and embodiment, high stable type grating of the present invention is adjusted frame to be described in detail:
As shown in Figure 1, 2, a kind of high stable type grating adjusts frame, including substrate 1, adjustable plate 2, semicircular plate 3, original screen panel
4 and locking pressing plate 5, substrate 1 is provided above adjustable plate 2,
Multiple spring 15 is installed between substrate 1 and adjustable plate 2,
On adjustable plate 2, end face is formed with semi-circular recesses 6, forms circular hole bottom groove 6,
Semicircular plate 3 is installed in groove 6, forms the circle with groove 6 bottom circular aperture precision-fit bottom semicircular plate 3
Axle, circular shaft is placed in circular hole；
Corner, adjustable plate 2 side is upwardly formed boss 7, and the another side angle of the side of broadside is outwardly formed flange 8 altogether；Boss
7 and the middle part of flange 8 and adjustable plate 2 and flange 8 edge that is in diagonal positions be respectively formed screwed hole,
Original screen panel 4 is perpendicularly fixed on semicircular plate 3, and fastens with screw, and original screen panel 4 front forms grating groove 9；
Locking pressing plate 5 is in " ㄇ " type, and left and right sides pars intramuralis is mounted on stud 10, and locking pressing plate 5 side sidewall is placed in
Above semicircular plate 3, another sidewall is placed in above adjustable plate 2, and by two studs 10 respectively with semicircular plate 3 and adjustable plate
2 fastenings；
Angle adjustment lever 11 is through the screwed hole of boss 7, and one end directly contacts with original screen panel 4；
Before adjustable plate pitching, adjusting rod 12 is through the screwed hole of flange 8, and one end directly contacts with substrate 1；
After adjustable plate pitching, adjusting rod 13 is through the screwed hole of the corner being in diagonal positions with flange 8, and one end with
Substrate 1 directly contacts；
