Description

Technical Field

[0001] This utility model relates to the field of gas detector technology, specifically to a split portable gas concentration detector. Background Technology

[0002] Gas concentration detectors are used in industries such as petrochemicals, natural gas extraction, coal, metallurgy, and pharmaceuticals to detect potentially leaked flammable and toxic gases, such as hydrogen, carbon monoxide, hydrogen sulfide, and chlorine, during production processes to ensure production safety and personnel health.

[0003] The technical solution provided in Chinese Patent Publication No. CN209372817U, entitled "A Portable Gas Detector," includes a housing. A switch button is located on the top left side of the housing, a buzzer is located in the center of the top of the housing, and an LCD display is fitted onto the top right side of the housing. Alarm lights are located on both the front and rear side walls of the housing. A charging port is located on the left side of the housing, and a sealing cover is located on the right side of the housing, with an air inlet on the right side of the sealing cover. A hanging groove is located at the bottom of the housing, and a hanging mechanism is installed within the inner cavity of the hanging groove. This utility model has a reasonable structural design, which improves the stability of the detector when held, facilitates carrying and use, reduces the possibility of falling from heights, and allows for continuous detection of the concentration of multiple gases. It also allows for arbitrary combinations of gases to be detected according to usage needs, improving the detector's performance and facilitating better detection of leaked gases.

[0004] To address the issue that existing gas detectors, when used outdoors, are mostly held directly in the hands of the testing personnel, there is a risk of them falling from heights due to the personnel's movement during testing. Current technology uses a movable column that rotates flexibly in a suspension groove, with a finger-loop ring to suspend it on the personnel's fingers, improving the detector's stability in the hand. However, this still presents the problem of inconvenience in installing the detector in the desired location, thus making the detector less convenient. Utility Model Content

[0017] A further improvement of this utility model is that the magnetic clamp is attached to the surface of the magnetic plate through the insertion hole, and the magnetic clamp installs the protective shell onto the surface of the detector body through the insertion hole and the magnetic plate.

[0018] A further improvement of this utility model is that the protective shell covers the surface of the LCD screen and is used to protect the LCD screen.
