[0002] Ambient air sampler is a device used to collect particulate matter, gas and other pollutants in the air. It is usually used to monitor air quality, understand the concentration of pollutants in the atmosphere, and evaluate their impact on human health and the environment. It is widely used in atmospheric environment monitoring, health and epidemic prevention, labor protection, scientific research and other units. It can also be used in conjunction with relevant instruments to analyze the sampled gas to understand the degree of environmental pollution by harmful gases, and provide the actual situation of pollution to the relevant competent authorities so that countermeasures can be taken to ensure that people have a healthy living environment;

[0003] Traditional ambient air particulate matter integrated samplers usually consist of a sampling head, a filter, a sensor, an instrument and a control system. The sampling head is responsible for introducing samples from the air, the filter is used to filter particulate matter in the air, the sensor and the instrument are used to monitor and measure the pollutant concentration in the collected samples, and the control system controls the working state of the sampler and the sampling process;

[0004] However, the structure of traditional ambient air particulate matter is relatively simple. The sampler cannot be quickly folded and unfolded when collecting and testing in outdoor environments. It is not convenient to carry when the sampling position needs to be frequently moved or changed outdoors. In addition, it is supported by an ordinary tripod, and its support stability is low on unstable ground. Therefore, a comprehensive sampler for ambient air particulate matter is proposed to solve the above problems. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 and Figure 2The utility model provides an embodiment: a comprehensive sampler for ambient air particulate matter, including a support plate 1, a hollow screw 2 is rotatably connected inside the support plate 1, a knob 3 is fixedly connected to the bottom end of the hollow screw 2, a sleeve 4 is threadedly connected to the outer wall of the hollow screw 2, a connecting block 5 is fixedly connected to the outer wall of the sleeve 4, a rotating rod 6 is rotatably connected inside the connecting block 5, one side of the rotating rod 6 is rotatably connected to a support seat 7, one side of the rotating rod 6 is fixedly connected to a fixed frame 8, a support frame 9 is fixedly connected to the bottom of the support plate 1, a slide groove 11 is opened inside the support plate 1, a connecting assembly is arranged inside the support frame 9, the connecting assembly is used to connect the rotating rod 6 for support, the connecting assembly includes a connecting rod 10, one side of the connecting rod 10 is rotatably connected to the inside of the support frame 9, the other side of the connecting rod 10 is rotatably connected to the inside of the fixed frame 8, and the connecting rod 10 is slidably connected to the inside of the slide groove 11.

[0033] Specifically, when it is necessary to support the sampler 20, first, by turning the knob 3, the force is transferred to the hollow screw 2 connected to the top, so that it rotates inside the support plate 1. This rotation will cause the hollow screw 2 to drive the sleeve 4 connected to the outer wall to move. At the same time, the movement of the sleeve 4 will transfer force to the connecting block 5 connected to the outer wall, causing it to move. The movement of the connecting block 5 will drive the internally connected rotating rod 6 to rotate, thereby pushing the fixed frame 8 connected on one side to move inside the support plate 1. The movement of the fixed frame 8 will also cause the internally connected connecting rod 10 to rotate inside the support plate 1, and the connecting rod 10 will slide inside the slide groove 11. When the connecting rod 10 moves to the appropriate position, the support seat 7 can be rotated to the ground to support the sampler 20, so that the sampler 20 can be conveniently and stably supported outdoors, thereby achieving the effect of easy retraction.

[0034] Reference Figure 1 , Figure 3 and Figure 4 A fixing block 12 is fixedly connected to the top of the support plate 1, a connecting frame 13 is fixedly connected to the top of the fixing block 12, a supporting block 14 is fixedly connected to the outer wall of the connecting frame 13, a worm 15 is rotatably connected inside the supporting block 14, a handle 16 is fixedly connected to one end of the worm 15, a worm wheel 17 is rotatably connected inside the connecting frame 13, and the worm wheel 17 is meshed with the worm 15.

[0035] Specifically, when the height of the sampler 20 needs to be adjusted, the force can be transferred to the worm 15 connected at one end by rotating the handle 16, causing the worm 15 to rotate inside the support block 14, so that the worm 15 drives the worm wheel 17 meshing with it to start rotating, thereby achieving the effect of motion transmission.

[0036] Reference Figure 1 , Figure 3 and Figure 4The worm gear 17 is internally threadedly connected with a threaded column 18, which is rotatably connected to the connection frame 13 and the interior of the fixed block 12. The top of the threaded column 18 is fixedly connected with a fixing seat 19, and a sampler 20 is arranged on the top of the fixing seat 19.

[0037] Specifically, the movement of the worm gear 17 transmits force to the internally connected threaded column 18. Through the threaded connection between the worm gear 17 and the threaded column 18, the threaded column 18 will move accordingly. This movement process drives the fixed seat 19 connected to the top to start moving, and the fixed seat 19 will drive the sampler 20 connected to its top to rise and fall, thereby achieving the effect of adjusting the height position of the sampler 20.

[0038] Working principle: when the sampler 20 needs to be supported, first turn the knob 3 so that the force drives the hollow screw 2 connected to the top to rotate inside the support plate 1, and the hollow screw 2 drives the sleeve 4 connected to the outer wall to move under the force, and the sleeve 4 drives the connecting block 5 connected to the outer wall to move under the force, and the connecting block 5 drives the internally connected rotating rod 6 to rotate under the force, and the rotating rod 6 drives the fixed frame 8 connected to one side to move under the force, and the fixed frame 8 drives the internally connected connecting rod 10 to rotate inside the support plate 1, and at the same time, the connecting rod 10 will slide inside the slide groove 11, and when it moves to the appropriate position, the support seat 7 is rotated to the ground for support, thereby achieving The sampler 20 can be easily stored outdoors. When the height of the sampler 20 needs to be adjusted, the handle 16 can be turned so that the worm 15 connected at one end is driven by force to rotate inside the support block 14. The worm 15 is driven by force to rotate the worm wheel 17 meshing with it. The worm wheel 17 is driven by force to rotate the internally connected threaded column 18. Through the threaded connection between the worm wheel 17 and the threaded column 18, the threaded column 18 is driven to move, thereby driving the fixed seat 19 connected to the top to move. The fixed seat 19 is driven by force to move the sampler 20 connected to the top, thereby achieving the effect of adjusting the height position of the sampler 20.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
