Abstract

The invention discloses a small nitrogen sealing structure, belongs to the technical field of optical monitoring, and aims to solve the problems of difficulty in disassembly of a sealing mode and difficulty in sealing of multiple wire harnesses in the prior art. The small-sized nitrogen sealing structure comprises an inner space ring, an outer space ring and a sealing ring, wherein one end of the inner space ring and a step surface at the front end of a lens are coaxially arranged; the outer fixing seat is coaxially arranged on the outer side of the inner space ring; and the window glass is coaxially arranged in the outer fixing seat, one side of the window glass is in contact with the positioning surface of the outer fixing seat, the other side of the window glass is in contact with the end surface of the other end of the inner space ring, and a nitrogen sealing cabin is formed among the lens, the inner space ring and the window glass. According to the small nitrogen sealing structure, through the design of the small nitrogen sealing cabin, the sealing cabin is shrunk to the position of the front end of the lens, a single sealing cabin and a single camera form a small assembly, and disassembly is convenient. If a monitoring system needs to be composed of a plurality of cameras, the cameras can be simply connected through a multi-channel gas pipe joint.

Description

technical field [0001] The invention belongs to the technical field of optical monitoring, and in particular relates to a small nitrogen sealing structure. Background technique [0002] When the outdoor monitoring system is in use, in an environment with low temperature and high humidity, the front glass of the lens will be fogged, blocking the light path. The traditional solution is to put the overall optical system into a sealed cabin, and at the same time, the cable harness outlet of the camera is also sealed with a sealant. This sealing method is difficult to disassemble. When the monitoring system is composed of multiple cameras, it is also difficult to seal the multi-wire harness. . Contents of the invention [0003] The purpose of the present invention is to propose a small nitrogen gas sealing structure, which solves the problems of difficult disassembly of the sealing method and difficulty of multi-wire harness sealing in the prior art. [0004] In order to achi...
