[0030] In order to make the purpose, technical scheme and advantages of the present application more clear, the following will make a further detailed description of the embodiments of the present application in combination with the drawings.

[0031] Please refer toFigures 1-5 The embodiment shown is a kind of manhole combustible toxic alarm measurement pre-processing device, comprising:

[0032] The pre-processing component includes box 11, connecting pipe 14;Connecting pipe 14 is installed in the inside of box 11;

[0033] The pre-processing component further includes detector 12, operator 13;Detector 12 is fixed between the rear connecting pipe 14, operator 13 is fixed between the inside of front connecting pipe 14;

[0035] Auxiliary mounting assembly, auxiliary mounting assembly includes magnetic ring 21, support rod 22, vertical rod 23, snap ring 24, movable slot 25 and spring 26;Magnetic ring 21 is adsorbed to the inside bottom of box 11, support rod 22 is screw connected to the top end inside of magnetic ring 21, vertical rod 23 is placed on the top end of support rod 22, snap ring 24 is fixed to the top end of vertical rod 23, movable slot 25 is opened in the inside of support rod 22 top, spring 26 is fixed between the inside of movable slot 25 and the bottom end of vertical rod 23;

[0036] Magnetic ring 21 is used for adsorbing the inside of box 11, support rod 22 is used for the movement of vertical rod 23, vertical rod 23 is used for the connection of snap ring 24, snap ring 24 is PVC plate, has tenacity, can be well with connecting pipe 14 is connected, movable slot 25 is used for the movement of spring 26 and vertical rod 23, spring 26 is used for the movement of vertical rod 23.

[0037] Vertical rod 23 moves in the inside of movable slot 25 through spring 26, a group of fixed rods 27 are fixedly connected to the top end periphery of support rod 22, guiding ring 28 is sleeved on the surface below vertical rod 23, snap ring 24 is connected with connecting pipe 14;

[0038] When spring 26 contracts and expands, vertical rod 23 rises or moves downward in movable slot 25 through spring 26, there are three fixed rods 27, fixed rod 27 is used for the connection of guiding ring 28, guiding ring 28 is used for the movement direction of vertical rod 23, when vertical rod 23 moves, it will move along the direction of guiding ring 28.

[0039] The bottom end of guiding ring 28 is fixedly connected with the top end of fixed rod 27, guiding groove 29 is opened on both sides of vertical rod 23, connecting block 281 is slidably connected in the inside of guiding groove 29, connecting block 281 is fixedly connected with the inside of guiding ring 28 at the opposite end;

[0040] The guide groove 29 is used for the connection and movement of the connecting block 281. The connecting block 281 is used for the connection between the guide ring 28 and the guide groove 29. When the vertical rod 23 moves through the spring 26, it causes the guide groove 29 to move along the direction of the connecting block 281, so as to avoid the vertical rod 23 from shifting position during the movement.

[0041] Working principle: When the component is not in use, the connecting pipe 14 is not installed. When the connecting pipe 14 is installed, hold the magnetic ring 21 by hand and attach it to the designated installation position on both sides. Hold the support rod 22 by hand and insert it into the magnetic ring 21. Press the retaining ring 24. The pressing force causes the spring 26 to contract, causing the vertical rod 23 to move the guide groove 29 along the direction of the connecting block 281 and the guide ring 28. The retaining ring 24 moves down in the movable groove 25 through the vertical rod 23 and the spring 26. After the retaining ring 24 moves down, rotate the support rod 22 by hand to make the support... The rod 22 is securely connected to the magnetic ring 21 by threads. Then, the two ends of the connecting pipe 14 to be installed are snapped into the retaining ring 24. Since the retaining ring 24 is made of PVC board, it is tough and snaps into the connecting pipe 14. Then, the weight of the connecting pipe 14 causes the spring 26 to contract, so that the vertical rod 23 drives the connecting pipe 14 to the designated installation position through the spring 26. Thus, the retaining ring 24 provides auxiliary support to the two ends of the connecting pipe 14 through the support rod 22 and the vertical rod 23, which makes it easier for the staff to connect the two ends of the connecting pipe 14 to the inside of the box 11.

[0042] The above steps, through the interaction between the spring 26 and the movable groove 25, cause the vertical rod 23 to move inside the support rod 22.

[0043] Please see Figure 1 , Figure 6 As shown, this embodiment, based on embodiment 1 above, further includes:

[0044] Place the limiting components;

[0045] The placement limiting assembly includes an annular plate 31, a limiting plate 32, and a fixing plate 33; the annular plate 31 is fixed to the outer surface above the support rod 22, the limiting plate 32 is fixed to the upper and middle edges of one side of the box 11, and the fixing plate 33 is fixed to the upper and lower middle edges of one side of the box 11.

[0046] The annular plate 31 is used to attract the magnetic plate 34, the limiting plate 32 limits the spring 26 and the vertical rod 23, and the fixing plate 33 is used to connect the magnetic plate 34.

[0047] A magnetic plate 34 is fixedly connected to the outer end of the fixed plate 33, and a plug-in hole 35 is opened in the center of the top and bottom ends of the magnetic plate 34.

[0048] The insertion hole 35 is engaged with the support rod 22, and the magnetic plate 34 is attracted to the annular plate 31;

[0049] The magnetic plate 34 is used for the opening of the insertion hole 35 and the adsorption of the annular plate 31, the insertion hole 35 is used for supporting the insertion of the support rod 22, when the clamping ring 24 is not used, the magnetic ring 21 is separated from the support rod 22, then the support rod 22 is inserted into the insertion hole 35, so that the magnetic plate 34 is adsorbed together with the annular plate 31 through magnetic force, thereby limiting the support rod 22 after insertion.

[0050] Working principle: when the assembly is not used, the magnetic plate 34 is in a separated state with the support rod 22, when the clamping ring 24 is not used, the magnetic ring 21 is rotated by hand, the magnetic ring 21 is separated from the support rod 22 through threads, then the clamping ring 24 is pressed by hand, so that the clamping ring 24 is lowered through the spring 26, and the support rod 22 is inserted into the insertion hole 35, so that the magnetic plate 34 is adsorbed together with the annular plate 31 through magnetic force, thereby limiting the support rod 22 after insertion, and the limiting plate 32 limits the clamping ring 24, thereby realizing the storage and placement of the support rod 22 after insertion.
