[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The extraction device for air quality detection is provided with a limit hole, a limit rod, a handle, a tension spring and a circular plate. When the air extraction device body needs to be installed on the mounting seat, the anti-slip sleeve is held with both hands and pulled outward to make the two handles move away from each other and stretch the tension spring, and the positioning groove is clamped on the positioning block to align the limit rod with the limit hole. At this time, the anti-slip sleeve is released, and the tension spring is reset to pull the circular plate and the limit rod, and the limit rod is inserted into the limit hole. At this time, the air extraction device body is fixed and the installation work is completed. When disassembling the air extraction device body, the above operation can be repeated in reverse.

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4As shown, the utility model provides a technical solution: an extraction device for air quality detection, comprising an air extraction device body 1, a U-shaped plate 2 is fixedly connected to the bottom of the air extraction device body 1, and a rainproof plate 3 is fixedly connected to the top of the air extraction device body 1. Because the rainproof plate 3 is provided, the rainproof plate 3 can prevent rainwater from falling onto the air extraction device body 1, and can protect the air extraction device body 1 from rain. At the same time, the rainproof plate 3 is designed as an inclined surface to avoid rainwater from accumulating on the rainproof plate 3. One end of two limit rods 10 is fixedly connected to a handle 6. Because the handle 6 is designed as an arc surface, the anti-slip cover 9 can better fit the palm of the person, thereby improving the comfort of operation.

[0022] Four limiting rods 10 are slidably connected to the U-shaped plate 2 . Two positioning grooves 15 are provided inside the U-shaped plate 2 . The positioning grooves 15 correspond to the positioning blocks 11 . A circular plate 13 is fixedly connected to the limiting rods 10 .

[0023] A tension spring 14 is sleeved on the limit rod 10, and both ends of the tension spring 14 are distributed and fixedly connected to the circular plate 13 and the U-shaped plate 2. A control panel 16 is arranged on the air extraction device body 1, and two handles 6 are symmetrically arranged about the middle part of the U-shaped plate 2. An anti-slip sleeve 9 is arranged in the middle part of the handle 6. Because of the anti-slip sleeve 9, the anti-slip sleeve 9 can play an anti-slip role and improve the stability of personnel operation. Positioning blocks 11 are fixedly connected on both sides of the mounting seat 4.

[0024] A bottom plate 5 is provided at the bottom of the U-shaped plate 2, and three supporting legs 7 are provided at the bottom of the bottom plate 5. A plurality of heat dissipation holes 8 are provided on both sides of the air extraction device body 1. Due to the heat dissipation holes 8, the heat emitted by the air extraction device body 1 during operation can be discharged from the heat dissipation holes 8, thereby preventing the air extraction device body 1 from being damaged due to excessive temperature inside the air extraction device body 1, and achieving the effect of dissipating heat for the air extraction device body 1. A mounting seat 4 is fixedly connected to the top of the bottom plate 5, and two limit holes 12 are provided on both sides of the mounting seat 4, and the limit holes 12 correspond to the limit rods 10.

[0025] The working principle of the utility model is:

[0026] When the air extraction device body 1 needs to be installed on the mounting base 4, hold the anti-slip sleeve 9 with both hands and pull it outward, so that the two handles 6 move away from each other and stretch the tension spring 14, and clamp the positioning groove 15 on the positioning block 11, so that the limiting rod 10 is aligned with the limiting hole 12. At this time, release the anti-slip sleeve 9, and the tension spring 14 resets the pulling circular plate 13 and the limiting rod 10, and insert the limiting rod 10 into the limiting hole 12. At this time, the air extraction device body 1 is fixed, and the installation work is completed. When disassembling the air extraction device body 1, repeat the above operation in reverse.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0028] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
