[0004] Regarding the above-mentioned related content, the following technical defects exist: when the filter device on the parameter instrument is blocked, you only need to replace it with a new filter device and continue to use the parameter instrument for detection. However, the connecting pipe between the parameter instrument and the filter device is inserted into the detection pipe mouth on the parameter instrument.

Because the filter device body is relatively cheap, when the filter device body is blocked, it is only necessary to replace the new filter device body to continue to use the parameter instrument body for detection. However, between the parameter instrument body and the filter device body, the connecting pipe is sleeved in the detection pipe mouth on the parameter instrument body. The connection between the pipelines will cause the filter device body to slip off the parameter instrument body, and the fixing effect of the connection between the pipelines is poor, which will affect the efficiency of detecting the pottery gas through the parameter instrument body.

[0014] Preferably, the support rod is a titanium alloy rod.

[0015] The effect achieved by the above components is that the surface of the rod body of the support rod made of titanium alloy is relatively hard, which is also why the surface of the rod body is less likely to deform when the support rod is used for a long time, and has a longer service life.

[0018] Preferably, a plurality of auxiliary blocks are fixedly connected to the arc surface of the sleeve, and the plurality of auxiliary blocks are evenly distributed on the arc surface of the sleeve.

[0019] The effect achieved by the above components is that when the sleeve is connected to the fixed rod by rotating it, the auxiliary block installed on the sleeve can increase the friction between the sleeve and the user's hand, thereby increasing the speed of connecting the sleeve to the fixed rod.

The side where the two clamps 205 are close to each other is provided with the same connecting disk 206. The circular arc surface of the connecting disk 206 is provided with a limiting groove 207. The two limiting grooves 207 are slidably connected with the two clamps 205. The end of the side of the clamp 205 away from the limiting groove 207 is fixedly connected with a threaded ring 208. The two threaded rings 2 The inner wall thread connection of 08 is connected with a screw 209 to connect the connecting pipe 11 with the gas-dedicated extraction pipeline, so that the gas content in the pipeline can be detected through the parameter instrument body 4. The filter tube 12 can filter the gas in the air to improve the gas purity when the gas is detected, thereby improving the accuracy of the gas test. Because the filter device body 1 is relatively cheap, when the filter device body 1 is blocked, it only needs to replace the new filter device body 1 to continue to use the parameter instrument body 4 for detection. However, the connection between the parameter instrument body 4 and the filter device body 1 is that the connecting pipe 11 is put into the detection pipe mouth on the parameter instrument body 4, and the connection between the pipelines is It will cause the filter body 1 to slip off the parameter instrument body 4, and the fixing effect of the connection between the pipes is poor, which will affect the efficiency of detecting the pottery gas through the parameter instrument body 4.

The connection speed of using the adjustment device 2 to connect the filter body 1 with the parameter instrument body 4 is faster, and the stability of the connection, that is, the air tightness, is higher, thereby improving the work efficiency of detecting the pottery gas through the parameter instrument body 4. The arc surface of the screw 209 is fixedly connected with a plurality of anti-skid grooves 210, and the plurality of anti-skid grooves 210 are evenly distributed on the arc surface of the screw 209. When the screw 209 is rotated in the two threaded rings 208, the screw 209 The anti-slip groove 210 installed on the top can increase the friction between the user's hand and the screw 209, and increase the speed of rotating the screw 209 in the threaded ring 208. One end of the screw 209 is fixedly connected with a guide block 211, and the cross-section of the guide block 211 is arc-shaped. When the screw 209 is connected to the threaded ring 208 on the clamp 205, the guide block 211 installed on the screw 209 can increase the speed of connection between the screw 209 and the threaded ring 208, thereby improving the efficiency of the connection between the screw 209 and the threaded ring 208.

Under the action of the telescopic rod 202, the support rod 204When the support rod 204 drives the clamp 205 to connect with the limit groove 207, the spring 212 installed on the telescopic rod 202 can assist the clamp 205 to connect with the limit groove 207 through the telescopic rod 202. The spring 212 can improve the connection efficiency between the clamp 205 and the limit groove 207. The support rod 204 is a titanium alloy rod. The surface of the support rod 204 made of titanium alloy is relatively hard. This is also why the surface of the support rod 204 is less likely to deform when used for a long time, and has a longer service life.

[0034] In the embodiments of the present invention, please refer to Figure 4 and Figure 5 The auxiliary device 3 includes a connecting plate 31, which is fixedly connected to the filter tube 12. The arc surface of the connecting plate 31 is movably connected to a rotating plate 32. The end of the rotating plate 32 away from the connecting plate 31 is fixedly connected to a bellows 36. The arc surface of the connecting plate 31 is fixedly connected to a fixed block 33. The side of the fixed block 33 away from the filter tube 12 is rotatably connected to a sleeve 34. The arc surface of the sleeve 34 is threadedly connected to a fixing rod 35. The fixing rod 35 is fixedly connected to the rotating plate 32. When the human nasal cavity inhales gas, the gas will cause poisoning. When the filter tube 12 filters the gas, the filter tube 12 will discharge the gas with impurities through the filter tube 12, which also leads to the use of the parameter instrument body 4 People will inhale gas, causing the people using the parameter instrument body 4 to show signs of poisoning. The auxiliary device 3 is installed on the filter tube 12. When the filter tube 12 discharges the gas with impurities from the filter tube 12, the auxiliary device 3 can discharge the gas to a distant place, thereby preventing the user from inhaling gas and causing poisoning.

When the sleeve 34 is rotated to connect with the fixed rod 35, the auxiliary blocks 37 installed on the sleeve 34 can increase the friction between the sleeve 34 and the user's hand, thereby increasing the speed of connecting the rotating sleeve 34 with the fixed rod 35.

[0035] The working principle of the special filter device for gas extraction pipe provided by the utility model is as follows: when it is necessary to connect the filter device body 1 with the parameter instrument body 4, the support rod 204 is pulled in the direction away from the fixed plate 201, and the movement of the support rod 204 will drive the telescopic rod 202 to be telescopic through the connecting rod 203, so that the clamp 205 can be driven to expand by pulling the support rod 204, and the clamp 205 is connected with the limiting groove 207 on the connecting plate 206, and then the screw 209 is used to connect with the threaded ring 208 on the clamp 205, and the clamp 205 can be fixed on the parameter instrument body 4 through the screw 209, so as to complete the connection between the filter device body 1 and the parameter instrument body 4. When the screw 209 is rotated in the two threaded rings 208, the anti-skid groove 210 installed on the screw 209 can increase the friction between the user's hand and the screw 209. The speed of rotating the screw rod 209 in the threaded ring 208 is increased. When the screw rod 209 is connected to the threaded ring 208 on the clamp 205, the guide block 211 installed on the screw rod 209 can increase the speed of the connection between the screw rod 209 and the threaded ring 208, thereby improving the efficiency of the connection between the screw rod 209 and the threaded ring 208. Under the action of the telescopic rod 202, the support rod 204 drives the clamp 205 to connect with the limiting groove 207. The spring 212 installed on the telescopic rod 202 can assist the clamp 205 to connect with the limiting groove 207 through the telescopic rod 202. The spring 212 can improve the efficiency of the connection between the clamp 205 and the limiting groove 207. The support rod 204 made of titanium alloy has a relatively hard rod surface, which is also why the support rod 204 is less likely to deform on its rod surface when used for a long time, and has a longer service life.

[0036] When it is necessary to discharge the gas with impurities through the filter tube 12, the rotating disk 32 is connected to the connecting disk 31, and then the fixed rod 35 on the rotating disk 32 is in contact with the sleeve 34, and then the sleeve 34 is rotated on the fixed block 33, so that the fixed rod 35 and the sleeve 34 can be fixed, so that the rotating disk 32 can be fixed on the filter tube 12, and the bellows 36 on the rotating disk 32 can be used to guide the angle of the gas discharged from the filter tube 12 to avoid the user of the parameter instrument body 4 from inhaling gas and causing poisoning. When the sleeve 34 is connected to the fixed rod 35 by rotating, the auxiliary block 37 installed on the sleeve 34 can increase the friction between the sleeve 34 and the user's hand, thereby increasing the speed of connecting the rotating sleeve 34 with the fixed rod 35.
