Technical Field

[0001] This utility model belongs to the technical field of atmospheric detection equipment, and in particular relates to a height-adjustable atmospheric sampler tripod. Background Technology

[0002] An atmospheric sampler is a specialized instrument used to collect samples of various pollutants in the atmosphere for monitoring and analysis of atmospheric environmental quality. It can quantitatively and qualitatively collect gaseous, aerosol, or particulate pollutants in the atmosphere, providing key sample data for fields such as environmental monitoring, meteorological research, and industrial hygiene testing.

[0003] In the field of atmospheric environmental monitoring, atmospheric samplers are widely used to obtain accurate atmospheric sample data. The tripod used in conjunction with the atmospheric sampler determines its stability during use. However, the adjustment method of the tripod is relatively simple and not precise enough, lacking effective positioning and scale markings. Operators find it difficult to control the three legs to be at the same height, and the three legs, which are set individually, have poor overall integrity, thus affecting the support stability. Therefore, it is necessary to provide a height-adjustable atmospheric sampler tripod with a visual height adjustment structure to ensure that the three legs are adjusted to the same height, and equipped with an internal support structure to improve the overall integrity of the three legs, thereby improving the support effect on the atmospheric sampler.

[0022] In the following description, embodiments of the height-adjustable atmospheric sampler tripod of the present invention will be described with reference to the accompanying drawings.

[0023] Figure 1-4This invention illustrates a height-adjustable atmospheric sampler tripod support according to an embodiment of the present invention. It includes a mounting platform 1, with support tubes 2 rotatably connected to the triangles at the bottom of the mounting platform 1. Support rods 3 are slidably connected to the inner cavity of the support tubes 2. Base feet 10 are rotatably connected to the bottom of the support rods 3. A fixing sleeve 4 is fixedly connected to the bottom of the surface of the support rods 3. Two deformation grooves 8 are formed on the bottom of the surface of the fixing sleeve 4. The deformation grooves 8 allow for deformation space for the two clamping plates 6. Under the threaded pull of the second threaded knob 7, the two clamping plates 6 retract, clamping the surface of the support rods 3. An internal support assembly 5 is provided at the bottom of platform 1. The internal support assembly 5 includes a limiting rod 51 fixedly connected to the center of the bottom of the mounting platform 1. A limiting sleeve 52 is slidably connected to the surface of the limiting rod 51. Three diagonal braces 53 arranged in a ring are rotatably connected to the surface of the limiting sleeve 52. The end of the diagonal brace 53 away from the limiting rod 51 is rotatably connected to the fixed sleeve 4. A first threaded knob 54 is threadedly connected to one side of the surface of the limiting sleeve 52. One end of the first threaded knob 54 penetrates into the inner cavity of the limiting sleeve 52 and is in close contact with the surface of the limiting rod 51. Through the setting of the internal support assembly 5, the diagonal braces 53 and the limiting sleeve... The combined use of 52 and limit rod 51 provides diagonal bracing for the bottom ends of the three support tubes 2, locking and limiting the unfolding angle of the three support tubes 2, thereby enhancing the overall stability of the three support tubes 2 and support rod 3, and the reliability of the support for the installation platform 1. The surface of the fixing sleeve 4 is provided with two clamping plates 6, with a second threaded knob 7 extending through one side of each clamping plate 6. The two clamping plates 6 are connected by threads. A positioning component 9 is provided at the top of the surface of the support rod 3. The positioning component 9 includes a rectangular groove 91 formed at the top of the surface of the support rod 3. A spring plate 92 is fixedly connected to the inner cavity of the rectangular groove 91. The surface of 92 is provided with a stamped and integrally formed protrusion 93. The surface of the support tube 2 is provided with multiple positioning holes 94 that are adapted to the protrusion 93. The surface of the support tube 2 is sprayed with scale marks 95. The sampler 11 is fixedly installed on the top of the mounting platform 1. It should be noted that the sampler 11 is an atmospheric sampler, which is a professional device used to collect samples of various pollutants in the atmosphere to assess and monitor the atmospheric environmental quality. It is an existing technology product, such as the ZR-3500D model produced by Qingdao Zhongrui Intelligent Instruments and the ADS-2062E model produced by Shenzhen Guoji Instruments Co., Ltd., etc., so it will not be elaborated on further.

[0024] Working Principle: When using this invention, the user pulls the support tube 2 to unfold it. During the rotation of the support tube 2, it pulls the diagonal brace 53 through the fixing sleeve 4, causing the diagonal brace 53 to rotate and drive the limiting sleeve 52 to slide on the surface of the limiting rod 51. The limiting sleeve 52 slides to the lowest point on the surface of the limiting rod 51. Then, the first threaded knob 54 is tightened, causing it to press against the surface of the limiting rod 51, thereby locking the limiting sleeve 52. At this time, the diagonal brace 53 provides stable support for the three support tubes 2. The three support rods 3 are slid according to the scale mark 95, so that the three support rods 3 are pulled out to the same length. During the sliding process of the support rods 3, the support rods 3 drive the spring plate 92 to slide in the inner cavity of the support tube 2, so that the spring plate 92 repeatedly expands and contracts, and then the protrusion 93 enters the inner cavity of different positioning holes 94 in sequence until the pulled-out length is determined. Then the protrusion 93 is engaged in the inner cavity of the current positioning hole 94, so that the pulled-out length is positioned. Finally, the second threaded knob 7 is tightened, so that the two adjacent clamping plates 6 are tightened, thereby clamping and fixing the surface of the support rod 3.

[0025] In summary, the height-adjustable atmospheric sampler tripod, through the cooperation of support tube 2 and support rod 3, provides triangular support for the installation platform 1. Then, through the cooperation of clamp plate 6, second threaded knob 7 and positioning component 9, the three support rods 3 are pulled out to the same length, thus achieving accurate control of the support height and stable and reliable support.
