[0026] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0027] Example 1, refer to the attached Figure 1 -Attached Figure 5 The utility model provides a dynamic flat plate method sampling bracket for the return air outlet of a medical and health institution, comprising:

[0028] A tray rack 1 is provided with a groove 2, and three trays 3 are arranged inside the groove 2;

[0029] There are two support rods 4, both of which are fixedly connected to the bottom of the pallet rack 1. The outside of the two support rods 4 is provided with a sleeve 5, and the outside of the two sleeves 5 is fixedly provided with a connecting block 6. The inside of the two connecting blocks 6 is provided with a bolt 7. One end of the two bolts 7 extends into the inside of the two sleeves 5 and contacts the two support rods 4 respectively. The bolts 7 are connected to the connecting block 6 and the sleeve 5 through the bolt 7. The outside of the two bolts 7 is fixedly provided with a knob 8;

[0030] There are two tripods 9 , which are respectively mounted on the outside of the bottom ends of the two sleeves 5 .

[0031] The tray 3 is slidably connected to the groove 2, and the bracket rod 4 is slidably connected to the sleeve 5;

[0032] Among them, in order to achieve the purpose of restriction, the present device adopts the following technical solution: the two bracket rods 4 are fixedly sleeved with a limit block 10 on the outside, and the limit block 10 can limit the length of the bracket rod 4 extending into the sleeve 5;

[0033] Among them, in order to achieve the purpose of knowing the total length of the support rod 4 and the sleeve 5, the present device adopts the following technical solution: the front side of the two support rods 4 is provided with a scale line 11, and the scale line 11 can know the total length of the support rod 4 and the sleeve 5;

[0034] In order to ensure the stable movement of the tray 3, the device adopts the following technical solutions:

[0035] Slide grooves 12 are provided on both the front and rear side walls of the groove 2. Slide blocks 13 are fixedly connected to the front and rear sides of the three trays 3, and the two slide blocks 13 are slidably connected to the inside of the two slide grooves 12 respectively. The design of the slide blocks 13 and the slide grooves 12 can ensure the stable lateral movement of the trays 3.

[0036] The inner diameter of tray 3 is 90 mm, which is convenient for placing culture dishes and culture dish covers;

[0037] The support rod 4 is perpendicular to the ground through the tripod 9; the minimum height of the sampling bracket after contraction is 300mm, and the maximum height after extension is 500mm; the tray rack 1 is at an angle of 30 degrees to the ground plane, and the length of the tray rack 1 is 800mm.

[0038] The usage process of the present invention is as follows: when using the present invention, the tray covers on the three trays 3 are opened, and then the culture dishes can be placed in the three trays 3. Since the tray rack 1 is set to an inclined shape and the angle with the ground is 30 degrees, when the sampling conditions are met, the device is placed at a distance from the return air outlet that meets the requirements, and the culture dish is placed in the tray 3. After exposure for 30 minutes, the culture dish cover is covered and sent for inspection in time, and culture is carried out as required, and pathogenic microorganisms are isolated when necessary.

[0039] When in use, if you need to adjust the height of the culture dish from the ground, turn the two knobs 8 to rotate the two bolts 7 so that the bolts 7 do not contact the support rods 4, and then pull the tray rack 1 upwards, so that the two support rods 4 can be pulled upwards, so that the support rods 4 can slide up and down in the sleeve 5, so that the overall length of the support rods 4 and the sleeve 5 can be adjusted, thereby adjusting the height of the tray rack 1 from the ground. After the height is adjusted, turn the knob 8 to make the bolts 7 squeeze the support rods 4, and then restrict the support rods 4, which can prevent the support rods 4 from moving up and down at will, and the height adjustment is convenient, you only need to pull the tray rack 1 and the support rods 4 upwards, so that when supporting the culture dish, you can appropriately adjust the height of the culture dish according to the usage scenario. Through height adjustment, this device can be suitable for different usage scenarios and has a wider range of applications.

[0040] The above description is merely a preferred embodiment of the present invention. Anyone skilled in the art may utilize the above-described technical solutions to modify the present invention or create equivalent technical solutions. Therefore, any simple modification or equivalent replacement based on the technical solutions of the present invention falls within the scope of protection claimed by the present invention.
