The fixing mechanism is connected to the ring plate 3 and the tripod mounting base 1;

[0027] The fixing mechanism includes steel sheets 6, a rotating shaft 7, a winding disc 8, and ropes 9. Four grooves 5 are formed in the positioning seat 2. Steel sheets 6 are welded in the four grooves 5. The four steel sheets 6 are all clamped with the ring plate 3. Through the cooperative design among the tripod mounting base 1, the ring plate 3, the comprehensive air sampler main body 14, and the fixing mechanism, not only can the effect of quickly disassembling and assembling the comprehensive air sampler main body 14 be achieved, improving the convenience, but also the stability is improved through the interaction between the four steel sheets 6 and the ring plate 3, and the practicability is higher.

[0028] In this embodiment, the rotating shaft 7 is rotatably connected to the tripod mounting base 1. A winding disc 8 is fixedly sleeved at one end of the rotating shaft 7. Four ropes 9 are fixedly connected to the winding disc 8. One ends of the four ropes 9 are respectively fixedly connected to the four steel sheets 6, facilitating synchronously pulling the four steel sheets 6 and enabling the four steel sheets 6 to respectively disengage from the four clamping grooves 11.

[0029] In this embodiment, four clamping grooves 11 are formed on the inner side of the ring plate 3. The four clamping grooves 11 are respectively adapted to the four steel sheets 6, facilitating the four steel sheets 6 to limit the ring plate 3. Springs 15 are fixedly connected to one sides of the four steel sheets 6. One ends of the four springs 15 are all fixedly connected to the positioning seat 2. The elastic potential energy of the four springs 15 facilitates the four steel sheets 6 to be respectively connected to the four clamping grooves 11.

[0030] In this embodiment, one end of the rotating shaft 7 penetrates through the tripod mounting base 1 and is fixedly connected to a rotating plate 10, facilitating rotating the rotating shaft 7.

[0031] In this embodiment, four through holes 12 are formed in the positioning seat 2. One ends of the four ropes 9 respectively pass through the four through holes 12, facilitating the four ropes 9 to pull the four steel sheets 6.

[0032] In this embodiment, the four steel sheets 6 all have a certain toughness. The ring plate 3 is adapted to the positioning seat 2, facilitating stable connection between the four steel sheets 6 and the ring plate 3.

[0033] In this embodiment, three feet 13 are provided at the bottom of the tripod mounting base 1 for supporting the main body 14 of the atmospheric comprehensive sampler. The specific structures and working principles of the three feet 13 and the main body 14 of the atmospheric comprehensive sampler can refer to the document with the application number: 202220882896.0 proposed in this application.

[0034] Working principle: During use, first, the three feet 13 at the bottom of the tripod mounting base 1 are spread out and fixed. Then, the ring plate 3 at the bottom of the main body 14 of the atmospheric comprehensive sampler is sleeved on the positioning seat 2, and the four card slots 11 are respectively corresponding to the four steel sheets 6. During this process, the ring plate 3 acts on the four steel sheets 6, causing the four steel sheets 6 to move into the four first grooves 5 respectively and causing the four springs 15 to store energy, and causing the four steel sheets 6 to store energy. After that, when the four card slots 11 are respectively corresponding to the four steel sheets 6, the four steel sheets 6 return to their original states and are engaged with the four card slots 11, thereby achieving the effect of limiting the ring plate 3, and further realizing the effect of quickly assembling the main body 14 of the atmospheric comprehensive sampler and the tripod mounting base 1;

[0035] After that, the atmosphere is collected through the collection head at the top of the main body 14 of the atmospheric comprehensive sampler;

[0036] When it is necessary to disassemble the main body 14 of the atmospheric comprehensive sampler, by rotating the rotating plate 10, the rotating shaft 7 rotates on the tripod mounting base 1. At the same time, the rotating shaft 7 drives the winding disc 8 to rotate synchronously and causes the winding disc 8 to wind the four ropes 9. At the same time, one ends of the four ropes 9 respectively pull the four steel sheets 6, and cause the four steel sheets 6 to disengage from the four card slots 11 respectively, thereby realizing the release of the limit on the ring plate 3, and then separating the ring plate 3 from the positioning seat 2, and further achieving the effect of quickly disassembling the main body 14 of the atmospheric comprehensive sampler.

[0037] The technical progress obtained by the present utility model compared with the prior art is that through the cooperation of various components, not only can the effect of quickly disassembling and assembling the main body 14 of the atmospheric comprehensive sampler be achieved, improving the convenience, but also the stability is improved through the interaction between the four steel sheets 6 and the ring plate 3, and the practicability is higher.
