[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0022] Example 1: Reference Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides an air sampler for indoor environmental testing, including a mounting plate 1, a support plate 2 rotatably connected to the inner wall of the mounting plate 1, three sets of sampling cylinders 3 arranged on the top of the support plate 2, a driving component 4 arranged on the outer side of the support plate 2, and a disassembly component 5 arranged on the outer side of the sampling cylinders 3.

[0023] The mounting plate 1 is designed to rotate the support plate 2. When the support plate 2 rotates, it can drive the sampling cylinder 3 to rotate, so that air can be sampled through the sampling cylinder 3. The drive component 4 is designed to drive the support plate 2 to rotate. The disassembly component 5 is set on the outside of the sampling cylinder 3. Therefore, the sampling cylinder 3 can be quickly disassembled by disassembly component 5, which is convenient and fast.

[0024] The drive assembly 4 includes a rotating rod 41 that rotates on the inner wall of the mounting plate 1. One end of the rotating rod 41 is fixedly connected to a gear 42. A gear ring 43 meshes with the outer side of the gear 42, and the inner wall of the gear ring 43 is fixedly connected to the outer side of the support plate 2.

[0025] Manually rotate the lever 41. When the lever 41 rotates, it can easily drive the gear 42 to rotate. When the gear 42 rotates, it can easily drive the gear ring 43 to rotate. When the gear ring 43 rotates, it can easily drive the support plate 2 to rotate.

[0026] The disassembly assembly 5 includes a first limiting ring 51 sleeved on the outside of the sampling cylinder 3. The inner wall of the first limiting ring 51 is rotatably connected to a mounting bracket 52 via a rotating shaft. The inner wall of the mounting bracket 52 is rotatably connected to a connecting rod 53. The outer side of the connecting rod 53 is rotatably connected to a connecting block 54. The bottom of the connecting block 54 is fixedly connected to a second limiting ring 55, and the bottom of the second limiting ring 55 is fixedly connected to the top of the support plate 2.

[0027] The first limiting ring 51 is used for rotatable connection with the mounting bracket 52. The mounting bracket 52 is used for connection with the connecting rod 53. A lever is fixedly connected to the outer side of the mounting bracket 52. The connecting rod 53 is used for connection with the connecting block 54, and the connecting block 54 is fixed to the outer side of the second limiting ring 55. Therefore, when the sampling cylinder 3 needs to be disassembled, the lever is moved to the left, causing the connecting rod 53 to rotate counterclockwise around the connecting block 54. Simultaneously, the mounting bracket 52 rotates around the inner wall of the first limiting ring 51, thus opening the mounting bracket 52 and the connecting rod 53 to the left, thereby causing the first limiting ring 51 to lift slightly upwards. Then, release the first limiting ring 51 from the sampling cylinder 3 and pull out the sampling cylinder 3. When it is necessary to install the sampling cylinder 3, first insert the sampling cylinder 3 into the first limiting ring 51 and the second limiting ring 55, and then move the lever to the right. After moving to the right, the mounting frame 52 will rotate clockwise around the inner wall of the first limiting ring 51. At this time, the first limiting ring 51 moves to the outside of the sampling cylinder 3 and can make the connecting rod 53 move to the right. The mounting frame 52 and the connecting block 54 can abut against the outside of the connecting rod 53 to achieve a fixing effect. In short, the sampling cylinder 3 is subjected to uniform pressure by rotating or moving the mounting frame 52 and the connecting rod 53.

[0028] Example 2: This is the second embodiment of the present invention, which is based on the previous embodiment.

[0029] Specifically, a connecting ring 6 is rotatably connected to the outer side of the first limiting ring 51, and the inner wall of the connecting ring 6 is rotatably connected to the outer side of the second limiting ring 55.

[0030] The connecting ring 6 is designed to connect with the second limiting ring 55 and allows the first limiting ring 51 to rotate. It should be noted that the size of the connecting ring 6 matches that of the sampling cylinder 3 and is installed on the outside of the sampling cylinder 3.

[0031] Specifically, a cap 7 is installed at one end of the sampling cylinder 3, and a sealing ring 8 is fixedly connected to the inner wall of the sampling cylinder 3 to prevent air leakage inside.

[0032] After the air inside the sampling cylinder 3 is sampled, the cylinder cover 7 can be closed to store the air and prevent leakage. At the same time, the sealing ring 8 is designed to seal the sampling cylinder 3 and prevent air leakage.

[0033] Example 3: This is the third embodiment of the present invention, which is based on the first two embodiments.

[0034] Specifically, four sets of connecting plates 9 are fixedly connected to the outside of the mounting plate 1, and each pair of connecting plates 9 is symmetrically designed.

[0035] The design of the connecting plate 9 facilitates connection with the mounting plate 1.

[0036] Specifically, the inner wall of the connecting plate 9 is fixedly connected with inclined plates 10, and the number of inclined plates 10 is set to four sets.

[0037] The inclined plate 10 is designed for fixing with the connecting plate 9.

[0038] Specifically, a support leg 11 is fixedly connected to one side of the inclined plate 10 by bolts, and a base 12 is fixedly connected to one end of the support leg 11.

[0039] The bottom angles of the four sets of support legs 11 and the base 12 are outward, which can better stabilize the device and prevent it from collapsing during operation.

[0040] Specifically, the outer side of the support leg 11 is fixedly connected to a connecting bracket 13 for improving stability.

[0041] The connecting frame 13 is designed with a cross-shaped structure and is connected to each set of support legs 11, thereby improving the stability of the support legs 11 and thus improving the stability of the overall device.

[0042] In use, first move the device to the desired position, open the cylinder cover 7, and then manually rotate the rotating rod 41. The rotation of the rotating rod 41 drives the gear 42 to rotate, which in turn drives the gear ring 43 to rotate. The rotation of the gear ring 43 drives the support plate 2 to rotate, which in turn drives the sampling cylinder 3 to rotate. When the sampling cylinder 3 rotates, air will be drawn into it. Then screw on the cylinder cover 7 to complete the air sampling. When it is necessary to disassemble the sampling cylinder 3, move the lever to the left to make the connecting rod 53 rotate counterclockwise around the connecting block 54. At the same time, the mounting bracket 52 rotates around the inner wall of the first limit ring 51, thereby... The mounting bracket 52 and connecting rod 53 open to the left, thereby causing the first limiting ring 51 to lift slightly upwards. Then, the first limiting ring 51 releases its restriction on the sampling cylinder 3, allowing the sampling cylinder 3 to be pulled out. When the sampling cylinder 3 needs to be installed, first insert the sampling cylinder 3 into the first limiting ring 51 and the second limiting ring 55, then move the lever to the right. After moving to the right, the mounting bracket 52 rotates clockwise around the inner wall of the first limiting ring 51. At this time, the first limiting ring 51 moves to the outside of the sampling cylinder 3, and the connecting rod 53 can move to the right. The mounting bracket 52 and the connecting block 54 can abut against the outside of the connecting rod 53 to achieve a fixing effect.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
