Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for microbial detection, and in particular to a petri dish placement support device. Background Technology

[0002] In the production processes of industries such as pharmaceuticals and food, the control of microbial contamination in cleanroom environments is crucial. Settling bacteria testing is one of the key methods for assessing the cleanliness of cleanroom environments, and this testing must be strictly performed in accordance with the GB / T16294-2010 standard. According to the standard requirements, during testing, sampling points must be evenly distributed according to the area of ​​the cleanroom. The culture dishes at each sampling point must be placed at a height of 0.8m-1.5m above the ground, and the culture dishes must not touch the ground to ensure that the collected settling microorganisms accurately reflect the microbial distribution status of the cleanroom environment. However, in actual on-site testing, there is often a lack of fixed desktops or supports with a height range of 0.8m-1.5m. Testing personnel often have to temporarily use equipment tables, shelves, etc. in the clean area as supports. However, the height of these supports is often difficult to accurately match the standard requirements, resulting in some petri dishes being placed too high or too low. Moreover, the stability of the temporary supports is insufficient, and the petri dishes are prone to tilting or shifting due to slight collisions. This not only affects the accuracy of the collection of settling bacteria but may also damage the petri dishes, ultimately leading to errors in the test results. This makes it impossible to effectively assess the true cleanliness of the clean area environment and poses a hidden danger to production quality control. Utility Model Content

[0003] The present invention aims to solve the problems mentioned in the background art by providing a petri dish placement support device to address the problem that the lack of a suitable fixed support at the detection site for sedimentation bacteria leads to the petri dish placement height not meeting national standards, thereby causing collection errors.

[0004] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a petri dish placement support device, comprising a base, a chassis, a turntable, and a support platform, wherein the turntable is provided on the top of the chassis; the base is fixedly connected to the top of the turntable; the base is in the shape of a "U"-shaped groove; a folding rod structure is movably connected to the upper end of the base; the support platform is movably connected to the upper end of the folding rod structure; damping elements are provided in the bearings at the folding connection of the folding rod structure and the connection of the support platform; a support structure is embedded in the folding rod structure near the base; after the folding rod structure is folded, the support platform and the chassis are placed parallel to each other in the storage structure.

[0005] Furthermore, the folding rod structure includes support rod A, support rod B, and support rod C; both ends of support rod A are arc-shaped; one end of support rod B is provided with ear plate two, and the other end is provided with ear plate three; the positions of ear plate two and ear plate three are correspondingly arranged; both ends of support rod A are hinged to the base and ear plate three of support rod B respectively through bearings; support rod B is hinged to one end of support rod C through ear plate two via bearings; one end of support rod C is hollow and open; both ends of support rod C are provided with a first positioning hole and a second positioning hole respectively; support rod D is inserted into the open end of support rod C; a ball positioning component passes horizontally through one end of support rod D, and the other end of support rod D is arc-shaped and is hinged to the support platform through ear plate one vertically arranged at the bottom of the support platform via bearings; the ball positioning component is used in conjunction with the first positioning hole and the second positioning hole respectively to play a telescopic role.

[0006] Furthermore, the support structure includes support rod a and support rod b; one end of support rod a is arc-shaped, and an extended pressing plate is provided near the outer side of the arc end; support rod b is inserted into the other end of support rod a; the support structure is movably connected to the four side walls of support rod A near the base through four shafts; the four side walls of support rod A are respectively provided with slots to accommodate the retracted support structure.

[0007] Furthermore, the storage structure includes a storage box, a pull-out block, and a baffle; the storage box is a hollow cuboid; one end of the pull-out block is perpendicularly connected to the baffle; the upper end of the pull-out block has a placement groove corresponding to the folded bracket; the outer side of the baffle has a handle; the two side walls of the baffle are respectively provided with fasteners; the storage box has fasteners on both sides near the opening; the pull-out block is inserted into the storage box, and the baffle is fastened to the storage box by the fasteners and fasteners.

[0008] Furthermore, the support platform is equipped with an anti-slip pad.

[0009] Compared with the prior art, this utility model has the following advantages: Through the multi-segment hinge structure of the folding rod, combined with the telescopic cooperation between the ball bearing positioning component on support rod D and the first and second positioning holes on support rod C, the height of the support platform can be precisely adjusted to the standard range of 0.8m-1.5m. This solves the detection error problem caused by the mismatch of the height of traditional temporary supports, ensuring that the collection of sedimented bacteria reflects the true microbial distribution in the clean area. The damping components in the bearings at each connection of the folding rod structure can fix the angle of the support rod to prevent slippage. The four sets of support structures on support rod A can form a stable triangular support with the ground to prevent tipping after extension. The anti-slip pads inside the support platform can prevent the petri dishes from slipping, providing multiple guarantees for structural stability and petri dish safety. The turntable on the top of the chassis can drive the support platform to rotate freely, and the folding rod structure can also flexibly adjust the angle of the support platform to adapt to different clean area layouts and spatial requirements, improving the flexibility of use. Moreover, the folding rod structure can be completely folded and stored in a storage box with pull-out blocks and fastening structure after folding. It is compact and easy to carry, while isolating external contamination. Attached Figure Description
