Abstract
Description
Technical Field
[0001] This utility model relates to the field of microbiological experimental tools technology, and in particular to an inoculation loop fixing bracket. Background Technology
[0002] In microbiology laboratories, inoculating loops are commonly used tools for bacterial culture and microbial manipulation. Because experimental procedures require a sterile environment, inoculating loops must be sterilized by high-temperature flame burning before use to prevent cross-contamination. Traditional inoculating loop procedures typically include the following steps: sterilizing the inoculating loop by burning it over the outer flame of an alcohol lamp, waiting for the loop to cool, using the loop for inoculation, and then sterilizing the loop again by burning it after use. However, existing inoculating loop holder designs have many shortcomings, limiting the efficiency and safety of experimental procedures.
[0003] Traditional inoculating loops require frequent heating and cooling during use, which can easily lead to slippage or contamination. Furthermore, existing inoculating loop holders are mostly simple, typically just a fixed support, failing to allow for rapid loop rotation and forcing operators to wait for the loops to cool, impacting experimental efficiency. In addition, existing holders have poor adaptability, usually only accommodating a single size of inoculating loop and unable to accommodate handles of different diameters. Height adjustment is limited, unable to precisely accommodate alcohol lamps of varying heights. The high temperature of the inoculating loop after heating poses a risk of burns to the operator, and the loop lacks stability when placed, easily slipping and creating a safety hazard. These problems make the development of a novel inoculating loop holder an urgent issue that needs to be addressed.
[0004] To address the problems of existing inoculation loop holders, this solution proposes a simplified inoculation loop fixing bracket. This bracket aims to improve operational efficiency, enhance adaptability, improve safety, and increase convenience. Specifically, this solution designs a bracket for alternating use of two inoculation loops, reducing the operator's waiting time for the loops to cool down and improving experimental efficiency. The design incorporates multiple slot sizes to accommodate inoculation loop handles of different diameters, improving the bracket's versatility. A stable tripod and anti-slip rubber pads ensure the bracket's stability during operation, reducing the risk of loop slippage. An adjustable-height connecting rod accommodates alcohol lamps of different heights, further enhancing operational convenience. Utility Model Content
[0005] In order to achieve the above-mentioned objectives and address the above-mentioned technical problems, this utility model provides an inoculation ring fixing bracket.
[0006] The technical solution includes a tripod, a disc, and a connecting rod connecting the tripod and the disc, wherein the tripod includes three legs;
[0007] Each leg of the tripod is equipped with an anti-slip rubber pad at its bottom to enhance stability and prevent the tripod from sliding during operation. The tops of the three legs of the tripod are fixedly connected by a ring plate in the middle. Several bottom connecting sleeves are provided on the outer wall of the ring plate, which are used to fix the connection to the connecting rod.
[0008] The disc has 6-8 semi-circular grooves evenly distributed along its edge for engaging the inoculation ring. Several top connecting sleeves are provided on the outer wall of the disc for fixing to the connecting rod. The tripod serves as the supporting foundation for the entire support, ensuring the stability of the overall structure.
[0009] The connecting rod is a solid stainless steel round rod, and several threaded holes are evenly distributed along the axial direction on the connecting rod.
[0010] Both the bottom connecting sleeve and the top connecting sleeve have transverse through holes on their outer walls that match the threaded holes.
[0011] The threaded holes and through holes are aligned and fixed together by bolts, which are used to fix the tripod and connecting rod, and the disc and connecting rod respectively; the connecting rod has a multi-hole design and an adjustment range of 10-30 cm, which can adapt to alcohol lamps of different heights.
[0012] The connecting rod connects the disk and the tripod, ensuring the vertical stability of the device. Simultaneously, the height adjustment function adapts to the needs of different experimental environments.
[0013] The longitudinal section of the groove is set to a gourd shape that is wider at the top and narrower at the bottom. The groove includes an inlet area and a locking area.
[0014] The width of the inlet area opening is slightly larger than the diameter of the inoculation loop handle, such as a 5mm handle corresponding to a 6mm opening.
[0015] The bottom width of the locking area is consistent with the diameter of the handle, precisely matching a tolerance of ±0.2mm, and the depth is 8-10mm;
[0016] The outer edge of the groove features a 15° guide bevel for easy one-handed insertion. The stepped groove ensures the inoculation loop doesn't slip out easily after insertion, while also facilitating quick removal and placement.
[0017] The tripod is made of stainless steel and is 15-20 cm high.
[0018] The diameter of the connecting rod is 8-10 mm.
[0019] The disc is made of stainless steel, with a thickness of 3-5 mm and a diameter of 10-15 cm, and its edges are polished.
[0020] The groove radius is available in 2-3 specifications, such as 3 mm, 5 mm, and 8 mm, to accommodate inoculation ring handles of different diameters. The inoculation ring handle is usually 1-5 mm.
[0021] The disc serves as a fixed platform for the inoculation loop, providing a stable placement position and supporting inoculation loops of various sizes.
[0022] The beneficial effects of the technical solution provided by this utility model embodiment are as follows: This solution provides a simple inoculation loop holder for microbiology laboratories, aiming to improve inoculation efficiency, enhance operational safety and convenience, and its advantages are specifically reflected in the following aspects:
[0023] (1) Improve operational efficiency: By designing a support for alternating use of dual inoculation loops, the time for operators to wait for the inoculation loops to cool down is reduced, which significantly improves experimental efficiency.
