Technical Field

[0001] This utility model relates to the field of waste gas collection technology, and in particular to a waste gas sampling port with a quick-release structure. Background Technology

[0002] Waste gas refers to toxic and harmful gases emitted by humans during production and daily life, especially by chemical plants, steel plants, pharmaceutical plants, coking plants, and oil refineries. The waste gas emitted by these plants has a strong odor and seriously pollutes the environment and affects human health. With the development of modern society, industrial waste gas emitted by various production enterprises is an important source of air pollutants. If a large amount of waste gas is discharged into the atmosphere without being treated to meet standards, it will inevitably lead to a decline in air quality and cause serious harm to human health. A search of existing Chinese patent technology reveals a "waste gas sampling device" with publication number "CN221056170U". This device uses a flexible barrier plate on the barrier component to unfold, which can seal the sampling port and prevent external oxygen from entering. However, the device is inconvenient to operate when connecting the sampling port to the exhaust pipe, which affects the efficiency of disassembling and connecting the sampling device.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0017] The following is combined Figures 1-5 This invention describes a waste gas sampling port with a quick-release structure.

[0018] In one embodiment, a waste gas sampling port with a quick-release structure includes: a sampling tube 1 and a connecting plate 2, wherein the sampling tube 1 is installed at the upper end of the connecting plate 2 and the lower end of the sampling tube 1 extends to the lower part of the connecting plate 2; and a quick-release mechanism 3 is installed on one side of the connecting plate 2; wherein the quick-release mechanism 3 includes a control component 31 installed on one side of the connecting plate 2, wherein a positioning component 32 is provided inside the control component 31, the lower end of the positioning component 32 abuts against the surface of the control component 31, and the upper end of the positioning component 32 extends above the control component 31; like Figure 1-5 As shown, the control component 31 includes a first positioning plate 311 fixedly connected to one side of the connecting plate 2. A connecting frame 312 is fixedly connected to the upper end of the first positioning plate 311. The interior of the connecting frame 312 and the upper end of the first positioning plate 311 are combined to form an inner compartment 315. A second positioning plate 313 is slidably connected to the inner wall of the inner compartment 315. Both the second positioning plate 313 and the first positioning plate 311 are fixedly connected to the ends away from the connecting frame 312 with a snap-fit ​​frame 314. The horizontal cross section of the snap-fit ​​frame 314 is V-shaped. The upper end of the second positioning plate 313 is provided with a guide groove 317. Multiple first snap teeth 316 are provided on both sides of the guide groove 317. The first snap teeth 316 are fixedly connected to the upper end of the second positioning plate 313. The multiple first snap teeth 316 are evenly distributed along the upper end of the second positioning plate 313. In this embodiment, the device slides inside the inner chamber 315 via the second positioning plate 313, so that the two snap-fit ​​brackets 314 snap into the exhaust pipe opening. The device can automatically adjust according to the size of the sampling pipe opening, thereby keeping the sampling tube 1 aligned with the exhaust pipe outlet and maintaining the effect of quick connection and disconnection of the sampling port. like Figure 1 , Figure 2 and Figure 5 As shown, the positioning component 32 includes an abutment plate 324 slidably connected to the inner wall of the inner compartment 315. A circular hole 322 is opened at the upper end of the connecting frame 312. A threaded sleeve 321 is fixedly connected to the inner wall of the circular hole 322. The threaded sleeve 321 is threadedly connected to the surface of the threaded post 323. A guide strip 325 is fixedly connected to the lower end of the abutment plate 324. A threaded post 323 is rotatably connected to the upper end of the abutment plate 324. The upper end of the threaded post 323 extends to the top of the connecting frame 312. Second locking teeth 326 are provided on both sides of the guide strip 325. The second locking teeth 326 are fixedly connected to the lower end of the abutment plate 324. In this embodiment, when the device is in use, the threaded column 323 is rotated. Under the action of the threaded column 323, the threaded sleeve 321 is engaged, which drives the abutment plate 324 to move longitudinally on the inner wall of the inner chamber 315. The guide strip 325 remains inside the guide groove 317. When the abutment plate 324 abuts against the upper end of the second positioning plate 313, the second locking tooth 326 and the first locking tooth 316 form a locking and positioning effect, making the installation and disassembly of the device more convenient.

[0019] Working principle: When in use, rotate the threaded column 323. Under the action of the threaded column 323, it cooperates with the threaded sleeve 321 to drive the contact plate 324 to move longitudinally on the inner wall of the inner chamber 315. The guide strip 325 is kept inside the guide groove 317. When the contact plate 324 abuts against the upper end of the second positioning plate 313, the second locking tooth 326 and the first locking tooth 316 form a locking position. The second positioning plate 313 slides inside the inner chamber 315. The two locking brackets 314 are locked at the exhaust pipe opening. The sampling tube 1 is kept aligned with the exhaust pipe outlet end to keep the sampling port quickly connected and disconnected.

[0020] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
