[0025] The following is a detailed description of the specific settings and functions of this embodiment. When it is necessary to use the air tester main body 1 to test the indoor air, the sealing plates 2 on the four sides are moved downward, so that the sealing plates 2 drive the movement of the support plate 4. Since the bottom end of the support plate 4 is positioned by the third rotary joint 13, the bottom end of the sealing plate 2 moves downward and drives the support plate 4 to expand horizontally until the support plate 4 is fully expanded and parallel to the ground. At this time, the height of the sealing plate 2 drops to below the air vent 6, so that the air vent 6 is fully open, and the air tester main body 1 receives air normally and performs quality monitoring. At this time, the support plate 4 is completely overlapped with the ground, which increases the surface area of the overall equipment installed on the ground and improves the stability of the equipment when in use;

[0026] When the air tester body 1 is not used for a long time, the sealing plate 2 is moved upward so that the sealing plate 2 drives the support plate 4 to rotate in the vertical direction until the support plate 4 is expanded from a horizontal state to a vertical state, and the support plate 4 is completely attached to the outer wall of the air tester body 1, and the sealing plate 2 is also completely attached to the outside of the air vent 6, thereby protecting the internal detection components and avoiding damage to the components caused by long-term exposure to the air.

The inner wall of the sealing plate 2 is fixedly connected with a magnet 14, and the outer wall of the air tester body 1 is fixedly connected with a magnetic seat 9. The magnet 14 is connected to the magnetic seat 9 by magnetic attraction. A second rotary joint 12 is provided at the bottom end of the guide rail 8, and the second rotary joint 12 is located above the third rotary joint 13.

The first rotary joint 10 is fixedly connected to the top end of the support plate 4, and the telescopic rod 5 is rotatably connected to the support plate 4 through the first rotary joint 10.

[0029] The effect achieved by the entire embodiment is that a telescopic rod 5 is set between the support plate 4 and the guide rail 8 for connection, and a triangular structure is formed between the telescopic rod 5, the support plate 4 and the guide rail 8. The telescopic rod 5 is used to perform secondary positioning of the position of the support plate 4 to improve the stability of the connection between the air tester main body 1 and the support plate 4. At the same time, a magnet 14 is set on the inner wall of the sealing plate 2, and a magnetic seat 9 is set on the outer wall of the air tester main body 1. When the sealing plate 2 is pushed upward to completely close the air vent 6, the magnet 14 and the magnetic seat 9 are docked with each other, and the position of the sealing plate 2 is fixed by magnetic attraction to prevent the sealing plate 2 from falling due to gravity. A pull ring 3 is set on the outer wall of the sealing plate 2. When the air tester main body 1 needs to be transported as a whole, a rope can be used to pass through the four pull rings 3 respectively, and the entire device can be hoisted and moved. When moving on flat ground, the casters under the air tester main body 1 can be used to slide on the ground.

[0030] The usage and working principle of this device: When testing the air, move the sealing plates 2 on the four sides downward. When the bottom end of the sealing plate 2 moves downward, it drives the support plate 4 to expand horizontally until the support plate 4 is fully expanded and parallel to the ground. The support plate 4 is completely overlapped with the ground, the air vents 6 are fully open, and the air tester body 1 receives air normally and performs quality monitoring;

[0031] When not in use, in order to protect the components inside the air tester body 1, the sealing plate 2 is moved upward so that the sealing plate 2 drives the support plate 4 to rotate in the vertical direction until the support plate 4 is expanded from a horizontal state to a vertical state, and the support plate 4 is completely attached to the outer wall of the air tester body 1, and the sealing plate 2 is also completely attached to the outside of the air vent 6. The position of the sealing plate 2 is fixed by magnetic attraction to prevent the sealing plate 2 from falling due to gravity.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
