DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] See also Figure 1 - Figure 6An adjustable air sampler bracket includes a sampler body 1, and the outer walls on both sides of the sampler body 1 are connected with an adjustment plug plate 2 and an adjustment bottom plate 3, the adjustment plug plate 2 is located directly above the adjustment bottom plate 3, the adjustment plug plate 2 and the adjustment bottom plate 3 are matched, and locking pieces are provided between the two groups of adjustment plug plates 2 and the adjustment bottom plate 3, the two locking pieces are respectively connected to the two sides of the sampler body 1, and a plurality of test tube jacks 201 are opened through the adjustment plug plate 2.

[0025] like Figure 1 - Figure 6 As shown, an adjustable air sampler bracket in the utility model is similar to the existing adjustable air sampler bracket structure, such as the model 2050 ambient air sampler. The main improvement of the utility model is that the user can more conveniently place the sampling tube through the bracket, thereby improving the convenience of the sampling operation. Figures 1 to 5 As shown, when the adjustable air sampler bracket in the utility model is in use, when a sampling test tube is used, the sampling test tube can be inserted into the adjustment plug plate 2 through the test tube socket 201, and the test tube can be lifted in cooperation with the adjustment base plate 3 at the bottom, so as to prevent the test tube from falling from the test tube socket 201 due to its small diameter, thereby completing the support and placement of the sampling test tube without the need for additional test tube brackets.

[0026] like Figure 1 - Figure 4 As shown, the adjustment plug plate 2 includes a fixed plug plate 4 and an extension plug plate 5, one end of the fixed plug plate 4 is connected to the sampler body 1, and the other end is connected to the extension plug plate 5 through a hinge, and the hinge is located on the side of the fixed plug plate 4 and the extension plug plate 5 away from the adjustment bottom plate 3. When more sampling test tubes are needed, the extension plug plate 5 can be flipped outward from the fixed plug plate 4 through the hinge, thereby increasing the number of test tube insertion holes 201 on the original basis, so as to facilitate the fixed support of more sampling test tubes.

[0027] like Figure 1 - Figure 6 As shown, both sides of the fixed plug plate 4 away from the end of the extended plug plate 5 are fixedly connected with a plug plate rotating shaft 6, and one side of the sampler body 1 close to the two plug plate rotating shafts 6 is fixedly connected with two plug plate connecting blocks 7, and the adjacent sides of the two plug plate connecting blocks 7 are provided with plug plate rotating holes 701, and the two plug plate rotating shafts 6 are respectively rotatably connected with the two plug plate rotating holes 701. When the test tube rack is not needed, the extended plug plate 5 can be flipped upward through the hinge to overlap with the fixed plug plate 4, and then the combined adjustment plug plate 2 can be flipped downward through the plug plate rotating shaft 6, so that it fits on the outside of the sampler body 1 and is fixed by the locking member, thereby preventing the adjustment plug plate 2 from shaking outward.

[0028] like Figure 1 - Figure 6As shown, a torsion spring 8 is fixedly connected in the plug plate rotating hole 701, and the other end of the torsion spring 8 is fixedly connected to the adjacent plug plate rotating shaft 6. When the locking member releases the restriction on the adjustment plug plate 2, the torsion spring 8 drives the plug plate rotating shaft 6 to rotate outward, thereby driving the fixed plug plate 4 to flip outward, and when supporting the sampling test tube, the torsion spring 8 can also prevent the fixed plug plate 4 from flipping downward, making the fixed support of the sampling test tube more stable.

[0029] like Figure 1 - Figure 4 As shown, the adjustment base plate 3 includes a fixed base plate 9 and an extension base plate 10. One end of the fixed base plate 9 is connected to the sampler body 1, and a matching groove 901 is provided on the upper surface of the other end. The end of the fixed base plate 9 close to the matching groove 901 is connected to the extension base plate 10 through a hinge. The hinge is located on the upper surface of the fixed base plate 9 and the extension base plate 10, and the matching groove 901 is matched with the extension base plate 10. When the extension plug plate 5 is used to provide support and fixation for more sampling test tubes, the extension base plate 10 can be flipped outward from the fixed base plate 9 through the hinge, so as to cooperate with the extension plug plate 5 to provide support for the bottom of the sampling test tube, and when the extension base plate 10 is retracted, the extension base plate 10 is flipped upward, and through the setting of the matching groove 901, the extension base plate 10 will not interfere with the outer wall of the sampler body 1 when it is retracted, so as to facilitate the retraction and fixation of the adjustment base plate 3 as a whole.

[0030] like Figure 1 - Figure 4 As shown, the two sides of the fixed bottom plate 9 close to one end of the sampler body 1 are fixedly connected with the bottom plate rotating shaft 11, and the side of the sampler body 1 close to the two bottom plate rotating shafts 11 is fixedly connected with two bottom plate connecting blocks 12, and the adjacent sides of the two bottom plate connecting blocks 12 are provided with bottom plate rotating holes 1201, and the two bottom plate rotating shafts 11 are respectively rotatably connected with the two bottom plate rotating holes 1201. By rotating the bottom plate rotating shaft 11 in the bottom plate rotating hole 1201, the adjustment bottom plate 3 can be turned upward and pressed against the side of the sampler body 1, and locked and fixed by the locking member, so as to be fixed and locked together with the retracted adjustment plug plate 2.

[0031] like Figure 1 - Figure 4As shown, the locking member includes a rotating rod 13 and a blocking rod 14. The rotating rod 13 is located between the adjusting plug plate 2 and the adjusting bottom plate 3 and is rotatably connected to the sampler body 1. The end of the rotating rod 13 away from the sampler body 1 is fixedly connected to the middle section of the blocking rod 14. The two ends of the blocking rod 14 are close to the sampler body 1 and are respectively against the adjusting plug plate 2 and the adjusting bottom plate 3. When the adjusting plug plate 2 is turned down and drips on the side of the sampler body 1, and the adjusting bottom plate 3 is turned up and abuts against the side of the sampler body 1, the blocking rod 14 can be rotated by the rotating rod 13, so that the blocking rod 14 is rotated from a horizontal state to a vertical state, so that the upper adjusting plug plate 2 and the lower adjusting bottom plate 3 are clamped on the side of the sampler body 1 at the same time, and the adjusting plug plate 2 and the adjusting bottom plate 3 are locked and fixed.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
