DETAILED DESCRIPTION

[0029] Referring to Figure 1 The utility model provides a technical scheme: an atmospheric particulate matter sampler, including sampler body 1, the upper surface of sampler body 1 is equipped with sampling tube 2 with screw thread, the upper end of sampling tube 2 is fixedly installed with sampling box 3, the surface of sampler body 1 is equipped with support device 4, the surface of rotating rod 406 is equipped with folding structure 5.

[0030] The specific setting and function of the support device 4 and the folding structure 5 will be described below.

[0031] Referring to Figures 1-5As shown, in the embodiment, the supporting device 4 comprises two limiting frames 401 fixedly connected to the surface of the sampler body 1, and a rotating rod 406 rotatably connected to the inside of each of the two limiting frames 401. A square tube 402 is fixedly installed at the end of the rotating rod 406 inside the limiting frame 401. A sliding plate 403 is slidably connected to the inside of the square tube 402. A plurality of insertion slots 409 are uniformly formed on the surface of the sliding plate 403. An installation plate 410 is fixedly installed on the surface of the square tube 402. An insertion frame 411 is slidably connected to the inside of the installation plate 410. An inclined surface structure is arranged at the lower side of the insertion frame 411. A first spring 412 is fixedly installed between the insertion frame 411 and the installation plate 410. Due to the inclined surface structure arranged at the end side of the insertion frame 411, the insertion frame 411 is irreversibly inserted into the corresponding insertion slot 409 on the sliding plate 403 when the sliding plate 403 moves relative to the insertion slot 409. When the sliding plate 403 is moved to the appropriate position, the insertion frame 411 is inserted into the corresponding insertion slot 409 on the sliding plate 403 under the elastic force of the first spring 412 on the installation plate 410, so as to achieve the preliminary locking of the sliding plate 403 after being pulled out. A pulling plate 408 is slidably connected to the inside of the sliding plate 403. A supporting plate 404 is fixedly installed at the other end of the pulling plate 408. The pulling plate 408 is arranged to limit the movement direction of the supporting plate 404. A driving rod 407 is threadedly connected to the inside of the sliding plate 403. The inside of the supporting plate 404 is rotatably connected to the driving rod 407. When the driving rod 407 is rotated, the driving rod 407 pushes the supporting plate 404 to move relative to the sliding plate 403. The surface of the supporting plate 404 is glued with a non-slip pad 405. The non-slip pad 405 increases the friction between the supporting plate 404 and the inside of the wall or cabinet, thereby further improving the stability of the atmospheric particulate matter sampler.

[0032] With reference to Figures 1-3 As shown, specifically, the unfolding structure 5 comprises a positioning block 51 fixedly connected to the side wall of the rotating rod 406. A bolt 53 is slidably connected to the inside of the positioning block 51. A plurality of insertion holes 55 are uniformly formed on the surface of the limiting frame 401. The size of the bolt 53 is matched with the size of the insertion hole 55. The bolt 53 is inserted into the inside of the insertion hole 55, so as to achieve the locking of the square tube 402 after being turned over. A circular block 52 is fixedly connected to the end side of the bolt 53. A second spring 56 is sleeved on the surface of the bolt 53. The two ends of the second spring 56 are fixedly connected to the circular block 52 and the positioning block 51, respectively. The circular block 52 is pulled by the second spring 56 on the positioning block 51 to drive the bolt 53 to be inserted into the inside of the insertion hole 55. The other end of the bolt 53 is fixedly connected to a convex head 54 in a circular truncated cone structure. The convex head 54 in the circular truncated cone structure improves the efficiency of the bolt 53 inserted into the inside of the insertion hole 55.

[0033] When the atmospheric particulate matter sampler needs to be used in a small space, first, rotate the two square tubes 402 inside the two rotating frames, and then turn the two square tubes 402 to the same straight line position. At this time, the slide plate 403 inside the square tube 402 can be pulled out. During the sliding process, the end side of the insertion frame 411 is provided with a slope, which plays an irreversible role during the relative motion between the slot 409 on the slide plate 403. When the slide plate 403 moves to the appropriate position, the insertion frame 411 will be inserted into the inside of the corresponding slot 409 on the slide plate 403 under the action of the elastic force of the first spring 412 on the mounting plate 410, which can realize the preliminary locking of the pulled-out slide plate 403. At this time, rotate the drive rod 407, which will push the support plate 404 to move relative to the slide plate 403. The setting of the pull-out plate 408 plays a role in limiting the movement direction of the support plate 404. At this time, the position of the support plate 404 can be adjusted to improve the tightness of the two support plates 404 in the narrow space. By setting the non-slip pad 405, the friction between the support plate 404 and the wall or the inside of the cabinet is increased, thereby further improving the stability of the atmospheric particulate matter sampler. By setting the supporting device 4, the stability of the atmospheric particulate matter sampler in the narrow space is improved through two adjustments, which avoids the inconvenience of using a tripod to support the atmospheric particulate matter sampler in a narrow space, and to some extent, expands the application range of the atmospheric particulate matter sampler.

[0034] By pulling the circular block 52, the pull-out work of the latch 53 can be realized. When the latch 53 is pulled out from the inside of the insertion hole 55, the rotating rod 406 inside the limiting frame 401 can be flexibly rotated, which facilitates the flexible folding and unfolding of the square tube 402 and the subsequent flexible carrying of the sampler body 1. After the square tube 402 is turned to the required angle, the latch 53 is released. At this time, the circular block 52 will be pulled by the second spring 56 on the positioning block 51 to drive the latch 53 to be inserted into the inside of the insertion hole 55, which can realize the locking of the turned square tube 402. By setting the convex head 54 with a circular cone structure, the efficiency of inserting the latch 53 into the inside of the insertion hole 55 is improved. By setting the folding and unfolding structure 5, the flexible locking of the turned square tube 402 is facilitated, and the flexible folding and unfolding of the square tube 402 is facilitated, thereby improving the flexibility of the supporting device 4.
