Technical Field

[0001] The utility model relates to the technical field of gas monitors, in particular to a multi-channel gas monitor. Background Art

[0002] A multi-channel gas monitor is a device used to monitor and detect the concentrations of multiple gases in the environment. A multi-channel gas monitor is usually connected to multiple detection heads, which can monitor whether different gases are leaking, thereby improving production safety.

[0003] Patent specification with announcement number CN217644067U discloses a multi-channel gas detection alarm controller chassis, including a protective box, moving wheels, a mounting plate, a partition, a gas detection alarm body, and detection probes. The moving wheels are installed around the bottom wall of the protective box. Guide support plates are symmetrically provided in the middle of the two inner side walls of the protective box. The guide support plates are provided with guide grooves. The mounting plate slides in the guide grooves. The gas detection alarm body is installed on the mounting plate. The partition is provided in the protective box and is located below the mounting plate. The front end of the gas detection alarm body is sequentially connected to multiple groups of wires. The partition is provided with a wire threading groove. The multiple groups of wires pass through the mounting plate and the wire threading groove and extend to the bottom of the protective box. There are multiple groups of detection probes, and the multiple groups of detection probes are electrically connected to the lower ends of the multiple groups of wires. This utility model relates to the technical field of gas detection equipment, specifically a multi-channel gas detection alarm controller chassis that is easy to disassemble and maintain and easy to retract and extend the wires.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned multi-channel gas detection alarm controller chassis has the following problems: when the device uses a detection head for detection, the detection head needs to be installed in a specified position by bolts. When the position of the detection head needs to be changed, the bolts need to be removed before the detection head can be removed, which makes it inconvenient to move the detection head when it is placed, and makes it inconvenient to adjust the height and direction of the detection head, which easily produces detection blind spots, thereby reducing the monitoring effect of the device. In view of this, a multi-channel gas monitor is provided to overcome the above-mentioned defects. Utility Model Content
