[0001] This utility model relates to the field of scientific research and experimental technology in the landscaping industry, and in particular to a microbial inoculation culture dish support for air quality testing in landscaping and green spaces. Background Technology
[0002] Microbial inoculation dishes are commonly used experimental tools for inoculating microorganisms with culture media during air quality testing. Currently, when conducting air quality testing in parks and green spaces, it is often common practice to manually hold the microbial inoculation dishes containing culture media on a recording board and place the bottom of the dishes at different locations in the green space for inoculation, or to place them side by side on a fixed experimental table for inoculation. The former wastes manpower, and the close-range manual operation can affect the natural settling speed and quantity of airborne particulate matter within the microenvironment, thus affecting the accuracy of experimental data acquisition. The latter is also affected by factors such as uneven distribution of the inoculation surface, easy confusion between the lid and the bottom of the microbial inoculation dish, and easy contamination of the inner surface of the lid, which can also affect the accuracy of experimental data acquisition. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a microbial inoculation culture dish support for air quality testing. This support utilizes a pull rod and two clamps in conjunction with an annular groove structure to securely clamp the lid of the microbial inoculation culture dish, thus preventing dust from entering and contaminating the lid.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a microbial inoculation culture dish support for air quality testing, comprising a support rod, a telescopic rod slidably connected to the support rod to form a telescopic structure, a rotating sleeve disposed on the upper side of the telescopic rod and rotatably connected to the telescopic rod, at least three evenly arranged support rods disposed on the periphery of the rotating sleeve and rotatably connected to the rotating sleeve, and a plug connecting the rotating sleeve and the support rods for fixing their positions, and further comprising: a rotating shaft rotatably connected to each support rod, wherein a pin is through-connected between the rotating shaft and the support rod;
[0005] A first tray and a second tray are respectively connected to each of the rotating shafts. The first tray contains the lid of the microbial inoculation culture dish, and the second tray contains the base of the microbial inoculation culture dish.
[0006] Two rotating grippers are disposed within the first tray; and a lever is provided that passes through the first tray and is connected to the two grippers, and when slid, can drive the grippers to clamp and release the caps of microbial inoculation culture dishes.
[0007] Preferably, the lid of the microbial inoculation culture dish is placed in the first tray, with the opening of the lid facing the bottom of the first tray. An annular groove is formed on the bottom surface of the inside of the first tray, and the width of the annular groove is greater than the width of the edge of the lid.
[0008] Preferably, the first tray is provided with a rotating support, the two grippers are located on the rotating support and are rotatably connected to the rotating support, the grippers are provided with rectangular grooves, and a cylindrical slider is slidably disposed in each of the two rectangular grooves, and the two cylindrical sliders are respectively fixedly connected to both ends of the pull rod.
[0009] Preferably, the first tray has two symmetrically formed sliding grooves inside, and the left and right parts of the pull rod slide in the two sliding grooves respectively. A spring block is slidably arranged in the sliding groove, the spring block is fixedly connected to the pull rod, and a spring is arranged between the spring and the bottom of the sliding groove.
[0010] Preferably, the two grippers are provided with anti-slip pads on the sides that are close to each other.
[0011] Preferably, the bottom of the support rod is provided with a fixed ball block, and three support legs are provided on the inner and outer circumferences of the fixed ball block.

[0028] Example 1
[0029] Figures 1-4 The illustration shows a microbial inoculation culture dish support for air quality detection according to one embodiment of the present invention.
[0030] like Figure 1-2 As shown, this embodiment provides a microbial inoculation culture dish support for air quality testing, including a support rod 1, a telescopic rod 2 slidably connected to the support rod 1 to form a telescopic structure, the telescopic rod 2 and the support rod 1 only need to achieve telescopic function, specifically, a spring block can be set inside the telescopic rod 2, and a groove can be set on the support rod 1, the spring block can be locked into the groove for limiting and fixing by sliding the telescopic rod 2, but it is not limited to this telescopic method. The telescopic rod structure is existing technology and will not be described in detail in this application. A rotating sleeve 3 is set on the upper side of the telescopic rod 2 and rotatably connected to the telescopic rod 2, at least three evenly arranged support rods 31 are set on the periphery of the rotating sleeve 3 and rotatably connected to the rotating sleeve 3, and a plug rod 32 connecting the rotating sleeve 3 and the support rods 31 for fixing their positions, and also includes: a rotating shaft 33 rotatably connected to each support rod 31, the rotating shaft and the support rod 31 being connected through a pin 34; a first tray 4 and a second tray 5 connected to each of the rotating shafts 33, the first tray 4 holding the microbial inoculation culture dish lid, and the second tray 5 holding the microbial inoculation culture dish bottom.
[0031] To prevent dust from adhering to the lid of the microbial inoculation culture dish when it is placed face down on the first tray 4, the rotating shaft 33 and the support rod 31 are designed to rotate. Before placing the lid of the microbial inoculation culture dish on the first tray 4, rotating the rotating shaft 33 can turn the first tray 4 face down to remove dust and debris, preventing dust accumulation from affecting the cleanliness of the lid. After the dust is removed, rotating the rotating shaft 33 turns the first tray 4 face up, and using the pin 34 to fix the rotating shaft 33 and the support rod 31, the bottom of the microbial inoculation culture dish with culture medium is placed on the second tray 5 for data collection. At the same time, placing the lid of the microbial inoculation culture dish face down on the first tray 4 can prevent dust from entering the lid of the microbial inoculation culture dish.
[0032] Two rotating grippers 41 are disposed within the first tray 4;
[0033] The two clamps can tighten the lid of the microbial inoculation culture dish, increasing the stability and practicality of the lid under sudden gusts of wind and preventing dust from entering.
[0034] A lever 42 that runs through the first tray 4 and is connected to the two clamps 41, and can drive the clamps 41 to clamp and release the lid of the microbial inoculation culture dish when sliding;
[0035] Pull the lever 42 to separate the two grippers 41, then place the microbial inoculation culture dish with the opening of the lid facing down inside.
[0036] Combination Figure 4 As shown, the lid of the microbial inoculation culture dish is placed in the first tray 4, with the opening of the lid facing the bottom of the first tray 4. An annular groove 43 is provided on the bottom surface inside the first tray 4, and the width D of the annular groove 43 is greater than the width d of the edge of the lid.
[0037] In this embodiment, inverting the lid of the microbial inoculation culture dish within the groove 43 reduces the risk of the lid being overturned by gusts of wind and also prevents dust from entering. Setting the width of the annular groove 43 to be greater than the edge width of the microbial inoculation culture dish lid increases the capacity for holding microbial inoculation culture dishes of different sizes.
[0038] Combination Figure 4As shown, the first tray 4 is provided with a rotating support 44 inside, and the two grippers 41 are located on the rotating support 44 and rotatably connected to the rotating support 44. The grippers 41 are provided with rectangular slide grooves 45 inside, and a cylindrical slider 46 is slidably arranged in each of the two rectangular slide grooves 45. The two cylindrical sliders 46 are respectively fixedly connected to the two ends of the pull rod 42.
[0039] In this embodiment, when the lever 42 is pulled, the cylindrical slider 46 slides within the rectangular groove 45, thereby causing the gripper 41 to rotate. Both grippers 41 can be operated simultaneously to open and close.
[0040] Combination Figure 4 As shown, the first tray 4 has two symmetrically arranged sliding grooves 47 inside. The left and right parts of the pull rod 42 slide in the two sliding grooves 47 respectively. A spring block is slidably arranged in the sliding groove 47. The spring block is fixedly connected to the pull rod. A spring 48 is arranged between the spring and the bottom of the sliding groove.
[0041] In this embodiment, after the pull rod 42 is stretched, the spring 48 is compressed by the spring block, and the spring 48 stores force. After the microbial inoculation culture dish lid is placed on the first tray 4 with the opening facing down, the pull rod 42 is released. At this time, the spring 48 releases its elastic force and drives the pull rod 8 to move towards the microbial inoculation culture dish lid through the spring block. Thus, the cylindrical slider 46 drives the two clamps 41 to move closer to each other and clamp the microbial inoculation culture dish lid. At the same time, this application can clamp culture dish lids of different sizes, increasing the versatility of the product.
[0042] Combination Figure 4 As shown, anti-slip pads 411 are provided on the side of the two grippers 41 that are close to each other.
[0043] In this embodiment, the anti-slip sticker 411 can increase the friction with the lid of the microbial inoculation culture dish, thereby improving the stability of the lid.
[0044] Combination Figure 1 As shown, a fixed ball block 6 is provided at the bottom of the support rod 1, and three support legs 7 are provided on the inner and outer circumferences of the fixed ball block 6.
[0045] In this embodiment, the three support legs 7 provide support and increase stability.
[0046] Combination Figure 1 As shown, the fixed ball block 6 has three support grooves 61, and the three support legs 7 are respectively rotatably arranged in the support grooves 61.
[0047] Combination Figure 1As shown, the support legs and the support groove are clamped and limited by screws.
[0048] In this embodiment, the clamping degree between the support leg 7 and the fixed ball block 6 can be adjusted by screwing in the screws, thereby achieving the fixation and rotation of the support leg 7.
[0049] Combination Figure 5 As shown, the depth h of the annular groove 43 is less than the depth H of the lid of the microbial inoculation culture dish.
[0050] In this embodiment, the solid part inside the groove 43 can be prevented from hitting the bottom of the microbial culture dish lid and causing contamination to the microbial culture dish lid.
[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
