The invention provides a grating adjusting mechanism which solves a plurality of problems in the background technology to a certain extent.
In order to solve the technical problems, the invention provides the following technical scheme:
the invention relates to a grating adjusting mechanism, which comprises a grating bottom plate and is characterized by also comprising a grating seat arranged on the grating bottom plate, wherein a grating is arranged in the grating seat, and a grating vertical adjusting port is arranged on the side of the grating; a coarse adjustment screw is arranged in the middle of the grating cover connected with the grating seat, a fine adjustment screw is arranged in the middle of the coarse adjustment screw, and a pressure spring is arranged between the fine adjustment screw and the grating.
As a preferable technical solution of the present invention, an inner end portion of the fine adjustment screw is provided with a protrusion used in cooperation with the pressure spring.
As a preferred technical scheme of the invention, a plurality of grating fixing holes are formed in the grating seat.
As a preferred technical scheme of the invention, the side of the grating is provided with a plurality of hexagonal fine tuning screws.
As a preferable technical scheme of the invention, the hexagonal fine-adjustment screws are distributed in a triangular mode.
The invention adopts a pressure spring for damping, and utilizes the pressure spring to adjust the front and back positions and add a pitch angle, thereby realizing the up-and-down movement of the grating. The grating is a shielding grating port, and in the fixed counter bore, reflected light and scattered light are blocked, so that the interference of background light is weakened, and the received spectrum is clearer. The grating is convenient to flexibly adjust, adjustment of all angles of light is basically met, the movement is stable, and the precision is controllable.
