[0006] The technical implementation scheme of the utility model is: a customs entrance and exit gas concentration detection device, comprising a detector, a connecting pipe, a fixing frame and an alarm, the lower side of the detector is connected with the connecting pipe, the rear side of the detector is connected with the fixing frame, and the right part of the detector is connected with the alarm.

[0007] Further, the connecting pipe is provided with a clamping groove.

[0008] Further, it further comprises a fixed pipe, a sealing ring and a valve, the valve is rotatably connected to the fixed pipe, and the sealing ring is connected in the fixed pipe.

[0009] Further, the valve is provided with a rotating handle.

[0010] Further, the sliding sleeve, spring, detent frame and torsion spring are further included, the sliding sleeve is slidably connected to the upper portion of the fixed tube, the spring is connected between the sliding sleeve and the fixed tube, the plurality of detent frames are rotatably connected to the upper side of the fixed tube, the torsion spring is connected between each of the detent frames and the fixed tube, each of the detent frames is in extrusion fit with the sliding sleeve, and each of the detent frames is clamped with the connecting tube.

[0011] Further, the protrusions are arranged on the detent frames.

[0012] The utility model has the advantages that: the connecting tube is placed between the detent frames, then the sliding sleeve is slid upward to extrude the detent frames to rotate and press and fix the connecting tube, when the detector needs to be disassembled and maintained, the sliding sleeve is slid downward, so that the detector can be taken down for repair, thereby achieving the effects that the detector can be conveniently installed and disassembled, and the installation and maintenance efficiency of the detector is improved.
