Description

Technical Field

[0001] The invention relates to microorganism detection technology, and in particular to a microorganism detection device. Background Art

[0002] Microbial testing is generally carried out by inoculating the sample solution onto the culture medium, culturing the microorganisms under suitable conditions, and finally counting and analyzing the visible colonies obtained. It is widely used in the fields of medical care, food, and pharmaceuticals. Microorganisms are widely distributed in nature because of their small size, light weight, strong adaptability, and strong reproductive ability. They exist in every corner that people can touch, such as food, cosmetics, feed, and the environment. The contamination of products by certain microorganisms not only affects the quality of the product itself, but more seriously, it endangers the health and safety of consumers. Therefore, microbial testing is often required in life, production, and the environment.

[0003] A Chinese invention patent with publication number CN116333872B discloses a microorganism detection device and a detection method thereof. The microorganism detection device and the detection method thereof are equipped with a positioning component in the detection sample placement mechanism. When the sample needs to be placed and positioned, the sample is directly placed in the center of the detection sample placement mechanism. At this time, the pressure rod is pressed down, and the clamping rod is synchronously lowered. The top of the clamping rod will be separated from the clamping hole at the bottom of the slider. At this time, the spring shaft will bounce the arc positioning plate sideways, and the other arc positioning plate will be triggered synchronously. The two arc positioning plates will position the sample at the same time. Through this design, the sample can be positioned while being placed, without the need for extra operations, which further improves the convenience of the device during operation and improves the use effect of the device.

[0004] When the existing equipment is used, during the process of detecting microorganisms, when the collected samples are placed in the culture tube, there are certain differences in the operations of different operators, and the bacterial activity of different collected samples is also strong or weak, resulting in differences in the location and number of bacteria in the culture tube. This makes it possible to have blind spots when the culture tube is placed in the microbial detection instrument for detection, resulting in poor microbial detection sensitivity of the culture tube, and problems of missed detection and wrong detection. In addition, in the process of placing the culture tube on the detection device, the culture tube is prone to tilt, which can easily lead to deviations in the results of the equipment detection. Therefore, a microbial detection device has been developed. Summary of the invention

When the telescopic member 261 is started, it synchronously drives the transmission rod 262 arranged at its output end to move, wherein the end of the transmission rod 262 is rotatably connected to the output end of the telescopic member 261. When the telescopic member 261 moves, it pulls the rotating rod 25 to move, so that the outer surface of the transmission rod 262 is engaged with the inner wall of the sleeve 26, thereby synchronously driving the transmission rod 262 to rotate.

[0046] Furthermore, a fixing cylinder 27 is provided at the upper end of the base 1 and on both sides of the rotating rod 25, and the end of the transmission rod 262 passes through and extends to the outside of the fixing cylinder 27. At the same time, a positioning block 263 is provided on the outer surface of the transmission rod 262, and a balance plate 28 is rotatably installed on the end of the positioning block 263, and the inner wall of the balance plate 28 is clamped with the inner wall of the transmission rod 262.

[0047] Specifically, when the transmission rod 262 rotates, the balance plate 28 is synchronously driven to rotate, and the transmission rod 262 is supported by the positioning block 263, so that the transmission rod 262 remains stable when rotating.

[0048] At the same time, a clamping block is provided in the inner cavity of the transmission rod 262 in the fixed cylinder 27. When the transmission rod 262 rotates, the transmission rod 262 and the clamping block are driven to move and clamp with the inner wall of the fixed cylinder 27, so that the transmission rod 262 remains stable.

[0049] Furthermore, both ends of the balance plate 28 are rotatably mounted with adjustment rods 281, and the upper end of the adjustment rod 281 is provided with a support plate 29, and the microorganism detection component is supported by the support plate 29.

[0050] Specifically, when the balance plate 28 rotates, the adjusting rods 281 installed at both ends are synchronously driven to move up and down, and the first slider 282 and the second slider 283 are used to limit the adjusting rod 281, so that the adjusting rod 281 does not shake when moving, and the microorganism detection part is supported by the support plate 29 provided on the upper end of the adjusting rod 281. The upper end of the support plate 29 is provided with a rubber pad or other anti-slip component, and the support plate 29 is used to move up and down, thereby ensuring that the microorganism detection part is in a horizontal state during detection.

[0051] Furthermore, the protection assembly 3 includes an adjustment plate 31 connected to the support plate 13, a fixing plate 32 is provided on the inner wall of the adjustment plate 31, and a driving member 33 is provided at one end of the fixing plate 32. A limiting plate 34 is provided on the inner wall of the adjustment plate 31, and the output end of the driving member 33 sequentially penetrates and extends to the outside of the limiting plate 34.

[0052] In this embodiment, the driving member 33 is a device with a telescopic function such as an electric telescopic rod, and is connected to an external control device. When the driving member 33 is started, it synchronously drives the push plate 35 arranged at its output end to move.

[0053] Furthermore, the cross section of the limiting plate 34 is concave, and the end of the limiting plate 34 is symmetrically provided with a guide groove 341. The inner wall of the guide groove 341 is slidably mounted with a slide bar 37, and an end of the slide bar 37 away from the limiting plate 34 is provided with an arc plate 38.

[0054] Specifically, when the slide bar 37 moves, it simultaneously drives the arc plate 38 disposed at its end to move toward the middle, thereby limiting the outer surface of the microorganism detection component. At the same time, the outer surface of the arc plate 38 is provided with a component having an anti-slip function such as rubber.

[0055] The guide groove 341 is used to limit the slide bar 37 so that when the slide bar 37 moves, no shaking occurs, thereby reducing the possibility of shaking of the microorganism detection component and ensuring the accuracy of the detection.

[0057] Specifically, when the driving member 33 is started, the push plate 35 is synchronously driven to move, and when the push plate 35 moves, the movable cylinder 351 is synchronously driven to move. Since the outer surface of the movable cylinder 351 is rotatably installed with the limit rod 36 to move, and the ends of the limit rod 36 are respectively rotatably connected to the slide rod 37 and the limit plate 34, the slide rod 37 is synchronously driven to move, so that the slide rod 37 moves toward the middle, thereby fixing the microbial detection component.

[0060] At the same time, the limiting member 11 is composed of an electric telescopic rod and a rubber block. The electric telescopic rod drives the rubber block to move, thereby limiting the moved microbial detection member, so that the microbial detection member is limited after leveling is completed, thereby ensuring the accuracy of the detection.

[0061] The control device can select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller Unit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., and is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but has a small storage capacity, a simple input and output interface, and low functional consumption.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
