A sealing device for a photoelectric instrument for rapid positioning and installation on a vehicle

Abstract

The invention relates to a sealing device of a vehicle-mounted rapidly located and installed photoelectric instrument and belongs to the sealing device in the technical field of photoelectric instruments. The invention aims at solving the technical problem: to provide a sealing device of a vehicle-mounted rapidly located and installed photoelectric instrument. According to the technical scheme, the sealing device of the vehicle-mounted rapidly located and installed photoelectric instrument comprises a locating plate, a locating plate screw, a locating plate slope, a sealing cover body slope, limiting blocks, a sealing cover body, sealing rings, flange grooves, fixing screws, flange screw holes, a base and the like. The locating plate is fixed at one side of the base through the locating plate screw, so that the sealing cover body slope and the locating plate slope which is arranged on the locating plate are parallel and matched. The limiting blocks are fixed on the base at two sides of the sealing cover body, so that the end faces of the limiting blocks at the two sides make contact with the locating plate. Each sealing ring is arranged in one flange groove formed in the sealing cover body, so that a sealing cover body assembly is formed. The sealing cover body slope is inserted in the locating plate slope. The sealing cover body assembly is fixed on the base, so that a photoelectric instrument inside the sealing cover body is sealed and protected.

Description

technical field [0001] The invention belongs to the technical field of optoelectronic instruments and relates to a sealing device for a vehicle-mounted optoelectronic instrument for fast positioning and installation. Background technique [0002] There are many kinds of optoelectronic equipment in the on-board equipment used for optical measurement. In order to ensure the quality of the photoelectric signal of the optoelectronic equipment and ensure the measurement accuracy, the on-board optoelectronic equipment needs to be installed in a sealed device. The large-scale optoelectronic equipment on the vehicle at home and abroad are protected by sealing devices during transportation. [0003] The closest prior art with the present invention is the sealing device developed by Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences. Such as figure 1 , figure 2 As shown, it includes a sealing cover body 1, a sealing ring 2, a flange groove 3, a ...

AI Technical Summary

Problems solved by technology

[0005] Photoelectric equipment needs regular repair and maintenance, and the sealing cover 1 needs to be removed frequently. In the vehicle, due to the small space in the vehicle and the compact installation of the equipment, sometimes it is impossible or inconvenient to disassemble the fixing screw 4 of the sealing cover 1 and the base 7. The sealing cover body 1 is not easy to disassemble, which will affect the timely repair and maintenance of the photoelectric equipment, and will bring consequences that affect the measurement accuracy
