Description

Optical rotation adjusting bracket

Technical Field

The utility model relates to the field of optical supports, in particular to an optical rotary adjusting support.

Background

Optical holders are widely used in the field of optical precision machines, and in the environments of industrial production, laboratory research and experiment, etc., optical elements are generally mounted in the holders for use. The conventional support only has a loading function and does not have an adjusting function, for example, a polarizing plate, a glan laser prism, a wave plate or even some crystal products, and due to the anisotropy of the conventional support, after the conventional support is installed in the support, an additional adjusting device is required in practical application to realize fine adjustment of focusing of light spots, an azimuth angle of an optical axis and the like, so that the problem of optical path adjustment is solved, and finally, the use requirement can be met.

Disclosure of Invention

In order to overcome the disadvantages of the prior art, the utility model provides an optical rotary adjusting bracket,

the technical scheme adopted by the utility model is as follows:

an optical rotary adjusting bracket comprises a rotary dial, a bearing, a middle seat, a loading piece, a spiral cover, an annular pressing ring, an adjusting rod, a fixed rod, a base and a locking screw. The bearing outer ring is embedded in an inner groove of the middle seat. The middle seat is provided with a central positioning reticle, rotary grooves on two sides and a threaded hole at the bottom. The rotary dial is embedded into the bearing inner ring and is locked by the locking screw. The outer side of the spiral cover and the loading piece are both provided with threads, and the spiral cover is screwed into the loading piece and is fixed in the rotary dial through the annular pressing ring. The adjusting rod is sleeved into an inner hole of the fixing rod and is locked through the locking screw. The middle of the base is provided with a threaded hole, and the two sides of the base are provided with elliptical through holes. The bottom of the fixed rod is provided with threads screwed into the center hole of the base.

And (3) an optical element is arranged in the bracket, the reticle is positioned according to the center of the middle seat, and the rotary dial is adjusted until the use requirement of the optical path is met.

The utility model has the advantages that: simple structure, small in size, simple to operate adjusts and makes accurately, and the practicality is strong, effectively satisfies the light path and adjusts the user demand.
