The invention relates to the technical field of oxygen content detection devices in air, and discloses a laboratory detection device for oxygen content in air, which includes a body, an installation box and an axis rod located inside the installation box are fixedly installed on the back of the body, the The inner side wall of the installation box is fixedly installed with the first bearing, and the inner side wall of the first bearing is fixedly installed with the winding tube located outside the axis rod, and the outer side of the axis rod is movably connected with one end extending to the outside of the axis rod Fixedly connected and the other end extending to a scroll spring fixedly connected to the inner wall of the winding drum. The air oxygen content laboratory detection device has the advantages of good protection and can be rolled up. It solves the problem that after use, the power cord will be disconnected from the power supply, and the power cord will fall to the ground. It is easy to step on the power cord plug under the condition of the power cord, causing damage to the power cord plug, and at the same time, the problem that the power cord cannot be rolled up.
Description
technical field [0001] The invention relates to the technical field of air oxygen content detection devices, in particular to a laboratory detection device for air oxygen content. Background technique [0002] Oxygen content in the air Under normal circumstances, the oxygen content in the atmosphere is about 21%. According to the research of scientists, if the oxygen content in the atmosphere exceeds 35%, it is very dangerous. The atmosphere is very prone to spontaneous combustion. There is a possibility of fire, and then the earth will become a sea of fire, a hell of life. [0003] The air oxygen content detection device used in the laboratory is generally an oxygen detector. After use, the power cord will be disconnected from the power supply, and the power cord will fall to the ground. It is easy for laboratory personnel to step on it without paying attention. The power cord plug causes damage to the power cord plug, and at the same time, the power cord cannot be rolle...
