Oxygen detector

Abstract

The present invention discloses an oxygen detector which comprises a sealing shell, a butt joint clamping base and a push-pull buckle, the butt joint clamping base is fixedly installed in the middle of the upper end of the sealing shell, the push-pull buckle is movably installed on the outer surface of one side of the sealing shell, and a first air pipe is fixedly installed in the middle of the upper end of the butt joint clamping base; a second air pipe is movably installed on the upper portion of the first air pipe, a rubber bent pipe is connected between the first air pipe and the second air pipe in a sleeving mode, fixing clamping rings are fixedly installed on the outer surfaces of one ends of the first air pipe and the second air pipe, and a threaded connection cap is fixedly installed on the outer surface of the other end of the first air pipe; and an air inlet groove is formed in the inner surface of the other end of the second air pipe, and a second limiting groove is formed in the side, close to the air inlet groove, of the inner surface of the other end of the second air pipe. The oxygen detector is provided with a spliced combined fixing structure, so that the oxygen detector is more convenient to mount and dismount, and meanwhile, the oxygen detector is provided with an angle adjusting structure, so that the use flexibility of the oxygen detector is improved.

Description

technical field [0001] The invention belongs to the technical field of detection equipment, in particular to an oxygen detector. Background technique [0002] Oxygen detector is a personal portable gas detection and alarm device. Its sensor adopts electrochemical sensor with sensitive response. It is suitable for continuously detecting the percentage concentration of oxygen in the ambient air of industrial and mining enterprises. When the ambient concentration is high, the high limit , Low-limit sound, light, and vibration alarms to warn the on-site personnel to evacuate from the dangerous area as soon as possible. [0003] A high-precision portable oxygen detector disclosed in the comparative document CN209102697U includes a protective case, and a rubber gasket is fixedly connected to the inside of the protective case, and the upper surface of the rubber gasket is fixedly connected to the top of the inner wall of the protective case. The lower surface of the rubber gasket ...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the fixed structural design of the traditional oxygen detector, the user cannot disassemble and store the probe structure of the oxygen detector after the oxygen detector is used, which makes the oxygen detector prone to damage during repeated use Phenomenon, which reduces the service life of the oxygen detector, making it impossible for users to carry out separate storage operations on the oxygen detector; at the same time, the traditional oxygen detector does not have a probe bending structure, so that the probe structure of the oxygen detector cannot be applied to different detection environments , which reduces the flexibility of the oxygen detector in use; secondly, the traditional oxygen detector has a fixed and adjustable structure, which makes the oxygen detector prone to falling off during use, reducing the stability of the oxygen detector in use, and providing an oxygen detector
