DETAILED DESCRIPTION

[0024] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0025] Please refer to Figures 1-5 The present application discloses a gas measuring device convenient to replace, which comprises a gas measuring instrument 1 and a rectangular mounting pipe 2. The gas measuring instrument 1 is the main structure of the device and is used for detecting different gases in the air. An air bellow 11 is arranged outside the gas measuring instrument 1, and a fan 12 is arranged inside the air bellow 11. The air bellow 11 is located at the air inlet of the gas measuring instrument 1, that is, the fan 12 blows air into the inside of the gas measuring instrument 1, so that the gas can enter the gas measuring instrument 1 more quickly, thereby achieving rapid detection. The rectangular mounting pipe 2 is a mounting structure and is used for mounting the gas measuring instrument 1. A mounting port 21 is arranged on one side of the outside of the rectangular mounting pipe 2. The mounting port 21 is used for mounting the rectangular mounting pipe 2 on the wall surface or different positions. A rectangular column 13 is arranged at the bottom of the gas measuring instrument 1. The rectangular column 13 is in sliding connection with the rectangular mounting pipe 2, that is, the rectangular column 13 connects the rectangular mounting pipe 2, so that the gas measuring instrument 1 can be mounted.

[0026] The upper side of the rectangular installation pipe 2 is provided with an installation slot 3, and the installation slot 3 is slidably provided with an installation piece 32. The installation piece 32 is clamped in the installation slot 3 and slides. One side of the installation piece 32 is provided with a fixing assembly. The fixing assembly is used for fixing a rectangular column 13. The fixing assembly comprises an inclined plug block 33. One side of the rectangular column 13 is provided with a rectangular groove 15. The inclined plug block 33 is disassembled in the rectangular groove 15. The other side of the installation piece 32 is provided with a first spring 34. The first spring 34 is connected to one side in the installation slot 3. The other side of the rectangular column 13 is provided with a limiting strip 14. The upper side of the other side of the rectangular installation pipe 2 is provided with a limiting rail 31. The limiting strip 14 is in sliding connection with the limiting rail 31. When the rectangular column 13 is inserted into the rectangular installation pipe 2, the limiting strip 14 is abutted with the limiting rail 31, so as to ensure the accurate insertion direction. The inclined surface on the upper side of the inclined plug block 33 enables the rectangular column 13 to directly extrude the inclined plug block 33 into the installation slot 3. When the rectangular column 13 is installed, the rectangular groove 15 is abutted with the inclined plug block 33. That is, the inclined plug block 33 is inserted into the rectangular groove 15 by the first spring 34, so as to fix the rectangular column 13. The installation of the gas measuring instrument 1 is completed.

[0027] The outer side of the installation slot 3 is provided with a pull opening 44. A pull rod 4 is movably arranged in the pull opening 44. The pull rod 4 slides and rotates in the pull opening 44.
