SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problems in the prior art and provides an optical element rotation adjusting bracket.

The utility model provides the following technical scheme:

a rotary adjusting bracket for an optical element comprises a base body, a rotary mandrel and a rotary adjusting mechanism, wherein the base body is rotatably connected with the rotary mandrel;

the fixed shaft is fixedly arranged on one side of the rotating mandrel, and one end of the fixed shaft is in threaded connection with a nut;

an optical element body mounted on the fixed shaft;

and the locking screw is arranged on the front end surface of the seat body.

Further, the nut is a knurled hand-screwed nut.

Furthermore, a support ring is arranged between the fixed shaft and the optical element body, the diameter of one end of the support ring is larger than that of the other end of the support ring, and the optical element body is sleeved at the end, with the small diameter, of the support ring.

Further, the support ring is made of POM plastic.

Further, an adjusting screw is installed on the other side of the rotating mandrel.

Furthermore, the fixed shaft is sleeved with a spring, and the spring is located between the support ring and the rotating mandrel.

Further, the optical element body is an optical filter.

The utility model has the beneficial effects that:

1. the optical density is adjusted by rotating the optical filter, and the optical element body is fixed at the finally determined position by locking the optical filter by using the locking nut after the angle adjustment is finished.

2. The optical element body can be installed and detached by screwing or unscrewing the nut, and the operation is convenient.

3. The optical element body is supported by the support ring, and the support ring is supported by the POM plastic material, so that the optical element body is protected and prevented from being damaged.

4. The optical element body is suitable for occasions needing frequent disassembly and replacement, and the disassembled parts cannot be separated from the support and are convenient to store.
