Laser interferometer with dustproof function

Abstract

The utility model belongs to the technical field of laser interferometers, and particularly relates to a laser interferometer with a dustproof function, the outer wall of a laser interferometer body is provided with a dustproof assembly, the dustproof assembly comprises a dustproof shell, the dustproof shell is fixedly connected to the outer wall of the laser interferometer body, and the dustproof shell is fixedly connected with the laser interferometer body. The outer wall of the dustproof shell is fixedly connected with a fixing frame, the inner wall of the fixing frame is rotationally connected with a threaded rod, and the outer wall of the threaded rod is in threaded connection with a threaded block. According to the laser interferometer with the dustproof function, through the use of the dustproof assembly, the device does not need to continuously operate an air purification system, so that the energy consumption is remarkably reduced, the energy-saving effect is particularly obvious under the occasions of long-time use or high-precision measurement, and in addition, the laser interferometer with the dustproof function is convenient to use. Due to the fact that noise and vibration generated by operation of the air purification system are avoided, the laser interferometer can keep higher precision and stability in the measurement process.
