[0023] See also Figure 1 - Figure 5 The utility model provides a detachable gas detection port device, including a detector body 1, a transfer sleeve 2 is arranged outside the detector body 1, one end of the transfer sleeve 2 is fixedly connected with a mounting bolt 21, the mounting bolt 21 is screwed with an interface at one end of the detector body 1, the other end of the transfer sleeve 2 is screwed with a trachea 3, a plugging component 4 is arranged inside the transfer sleeve 2, the plugging component 4 includes a first sleeve 41 and a first circular plate 42, one end of the first sleeve 41 is fixedly connected to one end of the inner wall of the transfer sleeve 2, the inner wall of the first sleeve 41 is aligned with the inner diameter of the mounting bolt 21, and an elastic telescopic rod 43 is vertically fixed at the center of the side wall of the first circular plate 42, One end of the elastic telescopic rod 43 is fixedly connected to a second circular plate 44, and a push rod 5 is fixedly connected to the interface at one end of the detector body 1 through a bracket, and one end of the push rod 5 contacts the center of the inner wall of the second circular plate through a bearing. The transfer sleeve 2 is used as a transfer structure to install the detector body 1 and the air pipe 3 through the mounting bolts 21 and the internal threads at the other end. The air passing through the transfer sleeve 2 is blocked and opened by the blocking component 4 inside the transfer sleeve 2. During the process of screwing the mounting bolts 21 on the detector body 1 and the transfer sleeve 2, the elastic force of the elastic telescopic rod 43 is overcome by the extrusion of the push rod 5 and the second circular plate 44, so that the air in the transfer sleeve 2 can be communicated.

[0024] like Figure 2 , Figure 4 and Figure 5 As shown, a positioning bent rod 421 is fixed between the outer walls of the first circular plate 42, one end of the positioning bent rod 421 is fixed to the other end of the inner wall of the transfer sleeve 2, and a second sleeve 45 is fixed to the side wall of the second circular plate 44. The inner wall of the second sleeve 45 and the outer wall of the first sleeve 41 slide with each other, and a plurality of first ventilation openings 411 are provided near one end edge of the outer wall of the first sleeve 41, and the plurality of first ventilation openings 411 are arranged at equally divided angles along the circumferential direction of the outer wall of the first sleeve 41, and a plurality of second ventilation openings 451 are provided on the outer wall of the second sleeve 45, and the plurality of second ventilation openings 451 are close to one end of the inner wall of the transfer sleeve 2, and the plurality of second ventilation openings 451 are arranged on the outer wall of the second sleeve 45. The openings 451 are respectively located at the projections of the plurality of first ventilation openings 411. The first circular plate 42 is fixed inside the transfer sleeve 2 with the cooperation of the positioning bent rod 421, and the second sleeve 45 is installed through the cooperation of the elastic telescopic rod 43 and the second circular plate 44. The second sleeve 45 and the first sleeve 41 are fitted on each other. When the first ventilation opening 411 and the second ventilation opening 451 are aligned, the gas can enter the inside of the detector body 1 from the first sleeve 41. When the first ventilation opening 411 and the second ventilation opening 451 are not aligned, the second sleeve 45 blocks the first ventilation opening 411, and the gas will not be discharged from the transfer sleeve 2 at this time.

[0025] Working principle: The transfer sleeve 2 is used as a transfer structure to install the detector body 1 and the air pipe 3 through the mounting bolts 21 and the internal thread at the other end. The air passing through the transfer sleeve 2 is blocked and opened through the sealing component 4. The first circular plate 42 is fixed inside the transfer sleeve 2 with the cooperation of the positioning bent rod 421, and the second sleeve 45 is installed with the cooperation of the elastic telescopic rod 43 and the second circular plate 44. The second sleeve 45 and the first sleeve 41 are mutually fitted. When the first ventilation opening 411 and the second ventilation opening 451 are relative to each other, the gas can enter the interior of the detector body 1 from the first sleeve 41. When the first ventilation opening 411 and the second ventilation opening 451 are not aligned, the second sleeve 45 blocks the first ventilation opening 411. The detector body 1 and the transfer sleeve 2 After the connection, the push rod 5 can apply an extrusion pressure to the second circular plate 44, so that the first ventilation opening 411 and the second ventilation opening 451 respectively opened on the first sleeve 41 and the second sleeve 45 are aligned with each other. At this time, the gas discharged from the air pipe 3 can enter the interior of the detector body 1 through the transfer sleeve 2 to be detected. When the detector body 1 needs to be replaced, the push rod 5 is gradually withdrawn from the transfer sleeve 2 during the disassembly of the detector body 1. At this time, the second circular plate 44 and the second sleeve 45 gradually move under the elastic extrusion pressure of the elastic telescopic rod 43, and the first ventilation opening 411 and the second ventilation opening 451 are no longer aligned. At this time, the gas is blocked by the transfer sleeve 2, and after the replacement of the detector body 1 is completed, the first ventilation opening 411 and the second ventilation opening 451 are restored, thereby restoring the function of the transfer sleeve 2 for gas transfer.

[0026] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
