[0026] Reference Figures 1-5 As shown in the utility model provides a technical scheme: a kind of for flue gas instrument's sampling nozzle structure, including first sampling tube 1 and second sampling tube 2.

[0027] The overall specific settings and effects are described below.

[0028] In the embodiment: the surface of first sampling tube 1 and second sampling tube 2 is provided with two reserved slots 3, and the side close to each other of the two reserved slots 3 is embedded with a sealing strip 4, and the circular arc surface of first sampling tube 1 and second sampling tube 2 is provided with external threads. By setting the sealing strip 4, the tightness of the installation between the first sampling tube 1 and the second sampling tube 2 is improved, and the phenomenon of gas leakage during sampling after installation between the first sampling tube 1 and the second sampling tube 2 is avoided. The surface of the first sampling tube 1 and the second sampling tube 2 is fixedly connected with a positioning pin 5, the surface of the first sampling tube 1 and the second sampling tube 2 is provided with an insertion hole 6, and the size of the positioning pin 5 and the size of the insertion hole 6 are matched. The positioning pin 5 provided on the first sampling tube 1 and the second sampling tube 2 is inserted into the inner side of the corresponding insertion hole 6, and the positioning of the first sampling tube 1 and the second sampling tube 2 can be realized at this time. The surface of the first sampling tube 1 and the second sampling tube 2 is provided with a limiting groove 9, the inner side of the limiting groove 9 is slidably connected with an arc plate 11, the surface of the first sampling tube 1 and the second sampling tube 2 is provided with a clamping groove 7, and the size of the clamping groove 7 and the size of the arc plate 11 are matched. The arc plate 11 is inserted into the inner side of the corresponding clamping groove 7, so that the locking work between the first sampling tube 1 and the second sampling tube 2 can be realized.

[0029] Specifically, the inner side of the limiting groove 9 is fixedly connected with an elastic sheet 10, and the elastic sheet 10 is located between the arc plate 11 and the bottom side of the limiting groove 9. The arc plate 11 is inserted into the inner side of the corresponding clamping groove 7 under the action of the elastic force of the elastic sheet 10. The surface of the arc plate 11 is provided with an anti-skid line 8. By setting the anti-skid line 8, the friction between the hand and the arc plate 11 is increased, which facilitates the operation of the arc plate 11. The surface of the sealing strip 4 is provided with a mounting hole. The positioning pin 5 passes through the mounting hole on the sealing strip 4 and is inserted into the inner side of the insertion hole 6.
