DETAILED DESCRIPTION

[0023] To make the person in this technical field more clearly and definitely the technical scheme of the utility model, the utility model is described in further detail below in conjunction with embodiment and drawing, but the implementation mode of the utility model is not limited to this.

[0024] Example 1

[0025] like Figures 1-4 As shown, this embodiment provides a sampling device for volatile organic pollutants, including a housing 1. A sampler 2 is installed inside the housing 1. An air inlet pipe 3 is installed on the top of the sampler 2. A sleeve 4 is fitted over the outside of the air inlet pipe 3. A threaded tube 5 is threaded to the bottom of the sleeve 4. A flexible tube 12 is fixed to the top of the sleeve 4. Limiting tubes 6 are symmetrically fitted over the outside of the flexible tube 12 and are movably connected to the flexible tube 12. A bidirectional internally threaded tube 15 is threaded to the outside of the limiting tube 6. A second threaded tube 13 is fixed to the top of the flexible tube 12. A collection tube 14 is threaded onto the top of the second threaded tube 13. A limiting disc 7 is fixed to the bottom side wall of the tube 6. The outer side of the limiting disc 7 is evenly provided with slots 8. A limiting ring 9 is rotatably installed on the top of the outer shell 1. The inside of the limiting ring 9 is evenly provided with blocks 10 that match the size of the slots 8. A fixing ring 16 is fixed to the top of the limiting tube 6. Side plates 17 are symmetrically installed on the top of the fixing ring 16 and on both sides of the collection tube 14. The side plates 17 are rotatably connected to both sides of the collection tube 14. A worm gear 20 is rotatably installed on one side of the side plate 17. A worm wheel 21 is rotatably connected on one side of the side plate 17 and on the top of the worm gear 20. The worm wheel 21 meshes with the worm gear 20.

[0026] Rotating the limiting ring 9 causes the stop block 10 inside the limiting ring 9 to rotate simultaneously until the stop block 10 rotates and aligns with the top of the slot 8. Then, lift the limiting plate 7, which drives the threaded tube 5 and the sleeve 4 to move upward. Then, unscrew the threaded tube 5 at the bottom of the sleeve 4. Separate the threaded tube 13 at the top of the hose 12 from the collection tube 14. Unscrew the collection tube 14 from the top of the threaded tube 13. The hose 12 can then be pulled out from inside the limiting tube 6 for cleaning and replacement. Rotating the worm gear 20 drives the worm wheel 21 to rotate, which in turn drives the collection tube 14 to rotate, causing the sampling port at the top of the collection tube 14 to rotate simultaneously to different angles. Then, the sampler 2 can be turned on to sample volatile organic pollutants from different locations.

[0027] Example 2

[0028] In this embodiment, as Figures 1-4 As shown, a limiting plate 18 is fixed to one end of the side plate 17. A fixing bolt 19 is threaded on the limiting plate 18, and the bottom of the fixing bolt 19 is movably connected to the top of the fixing ring 16.

[0029] Rotating the fixing ring 16 causes the collection tube 14 to rotate. After the collection tube 14 rotates to a suitable angle, the fixing bolt 19 is screwed down so that the fixing bolt 19 is tightly attached to the top of the fixing ring 16 to limit the angle of the collection tube 14. This can be used for collection work in different directions.

[0030] In the embodiment, the top of the fixing ring 16 is provided with a fixing pad, and the fixing pad is an anti-skid fixing pad.

[0031] The anti-skid fixing pad increases the friction between the top of the fixing ring 16 and the bottom of the fixing bolt 19, thereby improving the fixing effect on the rotation angle of the collecting pipe 14.

[0032] In the embodiment, the bottom of the limiting disc 7 is symmetrically provided with the plug plates 11, and the bottom of each plug plate 11 penetrates and extends into the inside of the shell 1.

[0033] The plug plates 11 make the limiting disc 7 more firmly installed on the top of the shell 1, thereby improving the installation firmness.

[0034] In the embodiment, the stoppers 10 are all triangular blocks, and the triangular blocks are rubber triangular blocks.

[0035] The rubber triangular blocks increase the friction between the bottom of the stopper 10 and the top of the limiting disc 7, thereby improving the limiting effect on the limiting disc 7.

[0036] The above is only further embodiments of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and concept of the present application within the disclosed range, and all of them belong to the protection scope of the present application.
