Description

Technical Field

[0001] The utility model relates to the technical field of gas detection sensors, in particular to a plug-in type multi-head universal sensor for gas detectors. Background Art

[0002] A gas detector is a converter that converts the volume fraction of a certain gas into a corresponding electrical signal. The detection head conditions the gas sample through the gas detector, usually including filtering out impurities and interfering gases, drying or refrigerating the instrument display part. A gas detector is a device that converts information such as the composition and concentration of a gas into information that can be used by personnel, instruments, computers, etc.

[0003] The existing 7-series sensors and 4-series sensors have proprietary models and connectors that are not interchangeable with each other. In addition, the connectors of the gas detectors are relatively fixed and not flexible enough to adjust, which results in a relatively small application range of the gas detectors. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] Gas detector plug-in multi-head universal sensor, including:

[0007] A detector housing, wherein a warning light is installed on the left side of the detector housing, and a bearing is installed on the right side of the detector housing, an outer tube is connected to the center of the bearing, a limiting block is welded on the right side of the inner wall of the outer tube, and a damping slider is movably connected inside the outer tube, a movable rod is installed on the right side of the damping slider, and a connecting rod is connected to the end of the movable rod, a first joint is installed on the top end of the connecting rod, and a second joint is installed on the bottom end of the connecting rod, a detection head is installed at the bottom of the detector housing, and a filter is embedded in the bottom surface of the detection head.

[0008] Preferably, a control panel is installed on the front of the detector housing, and a display screen is embedded in the center of the front of the control panel.

[0009] Preferably, a sliding structure is formed between the movable rod and the outer tube via a damping slider, and the outer wall of the damping slider is in contact with the inner wall of the outer tube.

[0010] Preferably, the outer tube and the detector housing are rotationally connected via a bearing, and the outside of the outer tube is tightly connected to the center of the bearing.

[0011] Preferably, the type of the first connector is a 7-series sensor connector, and the type of the second connector is a 4-series sensor connector.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0013] 1. In the utility model, the movable rod and the damping slider are connected together by a bearing, so that the movable rod and the damping slider can rotate relative to each other, thereby making the joint rotatable. When the movable rod is manually moved downward, the damping slider can be driven to move inside the outer tube, thereby adjusting the distance between the joint and the detector housing. It is convenient to use. By arranging two types of interfaces, a four-series interface and a seven-series interface, at the bottom of the joint, it can be used to connect devices with different interfaces, and the joint is flexible to adjust and has a wide range of applications.
