Description

Technical Field

[0001] The utility model relates to the field of biological enzyme detection, in particular to a rapid sampling device for biological enzyme detection. Background Art

[0002] The sampling device for biological enzyme detection generally refers to a device used to take samples for biological enzyme activity detection experiments. Enzyme activity, also known as enzyme activity, refers to the ability of an enzyme to catalyze a certain chemical reaction. The magnitude of enzyme activity can be expressed by the conversion rate of a certain chemical reaction catalyzed by it under certain conditions, that is, the faster the enzyme-catalyzed conversion rate, the higher the enzyme activity; conversely, the slower the rate, the lower the enzyme activity. Therefore, measuring enzyme activity is to measure the enzymatic conversion rate. The enzyme conversion rate can be expressed by the decrease in the amount of substrate or the increase in the amount of product in a unit volume per unit time. The determination of enzyme activity can be achieved by quantitatively measuring the change in the amount of product or substrate of the enzyme reaction with reaction time, or by quantitatively measuring the change in a certain property of the enzyme reaction substrate, such as viscosity change. Enzyme activity is usually measured at the optimal pH value and ionic strength of the enzyme and at a specified temperature.

[0003] According to the published patent 202121622175.8, a rapid sampling device for biological enzyme detection includes a sampling tube and a connecting tube arranged at the bottom of the sampling tube. The connecting tube is connected to the sampling tube. A fixing component is provided on the side of the sampling tube. The bottom end of the connecting tube is fixedly connected to a sampling head. A sealing component is provided on the side of the sampling head. The fixing component includes a mounting seat and a fixing column. The mounting seat is fixedly installed on the side of the sampling tube. The present invention is a rapid sampling device for biological enzyme detection. By setting a fixing component, when it is necessary to sample the biological enzyme, the sampling device is placed on a table, and by screwing the locking bolt, the adjusting column is pulled until it is stretched to the required height, so that the sampling head is located directly below the biological enzyme. In this way, the sampling device can be fixed, which is convenient for sampling. At the same time, by setting the adjusting column, the height of the sampling device can be adjusted. In the process of realizing the present invention, the inventor found that at least the following problems in the prior art have not been solved: although by setting a fixing component, when it is necessary to sample the biological enzyme, the sampling device is placed on a table, and by screwing the locking bolt, the adjusting column is pulled until it is stretched to the required height, so that the sampling head is located directly below the biological enzyme. In this way, the sampling device can be fixed, which is convenient for sampling. At the same time, by setting the adjusting column, the height of the sampling device can be adjusted. The height adjustment of the sampling device solves the problem that the rapid sampling device for bio-enzyme detection currently used on the market generally requires manual grasping of the tube body for extraction during sampling, which easily leads to the problem of instability of the device during extraction. However, during use, the traditional rapid sampling device for bio-enzyme detection still requires manual extraction of samples and manual operation of the height adjustment device. When extracting samples and adjusting the height of the device, manual operation is required to accurately and slowly adjust the height, resulting in a waste of a lot of time and affecting the overall efficiency of sample sampling. At the same time, due to manual sampling, the sample needs to be placed outside for observation and sampling adjustment, which is easily affected by environmental dust. Moreover, after the sampling is completed, the bottom of the sampling tube does not have a sealed structure, resulting in a portion of the sample flowing out from the bottom of the sampling tube after the sampling tube is taken out. For this reason, a new technical solution needs to be designed to solve the problem. Utility Model Content

[0004] The purpose of the present utility model is to overcome the deficiencies of the prior art, adapt to actual needs, and provide a rapid sampling device for biological enzyme detection to solve the problem that the current traditional rapid sampling device for biological enzyme detection still requires manual sampling of samples and manual operation of the height adjustment device. When manually extracting samples and adjusting the height of the device, manual adjustments need to be made accurately and slowly, resulting in a waste of a large amount of time and affecting the overall efficiency of sample sampling. At the same time, due to manual sampling, the sample needs to be placed outside for observation and sampling adjustment, which is easily affected by environmental dust. Moreover, after the sampling is completed, the bottom of the sampling tube does not have a sealing structure, resulting in a technical problem that a part of the sample will flow out from the bottom of the sampling tube after the sampling tube is taken out.

[0005] In order to achieve the purpose of the present invention, the technical solution adopted by the present invention is to design a rapid sampling device for biological enzyme detection, including a sampling cylinder and:

[0006] Two fixing rods are fixed on both sides of the sampling cylinder;

[0007] A quick sampling mechanism is fixed between the two fixed rods, comprising a micro pump body, the top of which is connected to a pipe plug, the top of which is a sealed structure, with openings on both sides of the pipe plug, and the bottom of which is connected to an extraction tube;

[0008] The top of the pipeline plug passes through the feed pipe and extends into the sampling tube body, and the bottom of the sampling tube body is connected to the feed pipe.

[0009] Preferably, the top of the sampling tube body passes through the sampling cylinder, the top of the sampling tube body is connected to a connecting tube, and the top of the connecting tube is detachably connected to a tube cover.

[0010] Preferably, circular grooves are provided on both sides of the bottom end of the sampling tube body, a first fixing cylinder is installed inside the circular groove, and a second fixing cylinder passes through the top of the first fixing cylinder.

[0011] Preferably, a spring is fixed to the bottom end of the first fixed cylinder, a movable plate is fixed to the top of the spring, a second fixed cylinder is fixed to the top of the movable plate, and a pressure plate is fixed to the top of the second fixed cylinder.

[0012] Preferably, the bottom of the sampling cylinder is an open structure, and a cylinder bottom shell is installed at the bottom of the sampling cylinder.

[0013] Preferably, a micro electric telescopic cylinder is installed at the bottom end of the inner bottom shell of the cylinder, and a push plate is fixed on the top of the micro electric telescopic cylinder through the bottom shell of the cylinder.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model combines a micro pump body, a pipeline plug and a feed pipe, and can connect the feed pipe at the bottom of the sampling tube with the pipeline plug at the top of the micro pump body. The micro pump body is provided, and the sample can be directly drawn into the sampling tube body. The staff can control the amount of sample drawn in by opening and closing the micro pump body, eliminating the need for manual sample extraction. Moreover, after the sample is placed on the surface of the push plate, the push plate and the sample can be driven up and down by the micro electric telescopic cylinder, so that the height of the sample can be conveniently adjusted without adjusting the entire sampling tube up and down, solving the problem of traditional rapid sampling devices for biological enzyme detection, which still require manual sample extraction and manual operation of the height adjustment device. When extracting samples and adjusting the height of the device, manual adjustments need to be made accurately and slowly, resulting in a waste of a lot of time, affecting the overall efficiency of sample sampling.

[0016] 2. The utility model combines the sampling tube body, the spring and the pressure plate, and can use the elastic force of the spring to drive the pressure plate to move downward, thereby sealing the connection between the feed tube and the sampling tube body. When the pipe plug is inserted into the sampling tube body, the pipe plug will press the pressure plate upward, thereby inputting the sample into the sampling tube body. When the sample input is completed, the pipe plug is removed, and the elastic force will drive the pressure plate to seal again, thereby realizing self-sealing of the sampling tube, solving the technical problem that after the sampling is completed, there is no sealing structure at the bottom of the sampling tube, resulting in a part of the sample flowing out from the bottom of the sampling tube after the sampling tube is taken out.

[0021] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0022] Example 1: A rapid sampling device for enzyme detection, see Figures 1 to 3 , including a sampling cylinder 1, and also including: two fixed rods 2, fixed on both sides of the interior of the sampling cylinder 1; a rapid sampling mechanism, fixed between the two fixed rods 2, the rapid sampling mechanism includes a micro pump body 201, the top of the micro pump body 201 is connected to a pipe plug 202, the top of the pipe plug 202 is a sealed structure, and openings are opened on both sides of the pipe plug 202. The bottom of the micro pump body 201 is connected to an extraction pipe 203; the top of the pipe plug 202 passes through the feed pipe 305 and extends into the sampling tube body 204. The bottom of the sampling tube body 204 is connected to the feed pipe 305. First, extend the sampling tube body 204 into the sampling cylinder 1, and insert the feed pipe 305 at the bottom of the sampling tube body 204 into the tube The micro pump body 201 is directly opened and closed when sampling is required, thereby adjusting the amount of sample drawn into the extraction tube 203. Moreover, after the sample is placed on the surface of the push plate 103, the push plate 103 and the sample can be driven up and down by the micro electric telescopic cylinder 102, so that the height of the sample can be conveniently adjusted without adjusting the entire sampling tube up and down. This solves the problem of traditional rapid sampling devices for bio-enzyme detection, which still require manual sample extraction and manual operation of the height adjustment device. When extracting samples and adjusting the height of the device, manual adjustments need to be made accurately and slowly, resulting in a waste of a lot of time and affecting the overall efficiency of sample sampling.

[0023] For details, see Figure 1 The top of the sampling tube body 204 passes through the sampling cylinder 1, and the top of the sampling tube body 204 is connected to a connecting tube 205, and the top of the connecting tube 205 is detachably connected to a tube cover 206.

[0024] For further information, see Figure 3 Circular grooves 3 are provided on both sides of the bottom of the sampling tube body 204 , a first fixed cylinder 301 is installed inside the circular groove 3 , and a second fixed cylinder 303 passes through the top of the first fixed cylinder 301 .

[0025] It is worth noting that, see Figure 3The top of the bottle 303 is fixed with a spring 302, and the top of the bottle 303 is fixed with a movable plate 306. The top of the movable plate 306 is fixed with a second fixed bottle 303, and the top of the second fixed bottle 303 is fixed with a pressing plate 304. Since the spring 302 is provided in the first fixed bottle 301, the elastic force of the spring 302 will drive the pressing plate 304 to move downward, thereby sealing the connection between the feeding pipe 305 and the sampling tube body 204. When the pipe plug 202 is inserted into the sampling tube body 204, the pipe plug 202 will press the pressing plate 304 to move upward, thereby inputting the sample into the sampling tube body 204. When the sample input is completed, the pipe plug 202 is removed, and the elastic force will drive the pressing plate 304 to seal again, thereby realizing self-sealing of the sampling tube, solving the technical problem that after the sampling is completed, there is no sealing structure at the bottom of the sampling tube, which causes a part of the sample to flow out from the bottom of the sampling tube after the sampling tube is taken out.

[0026] It is worth noting that see Figure 1 The bottom of the sampling cylinder 1 is an open structure, and a cylinder bottom shell 101 is installed at the bottom of the sampling cylinder 1.

[0027] It is worth mentioning that see Figure 2 A micro electric telescopic cylinder 102 is installed at the bottom end of the cylinder bottom shell 101, and a push plate 103 is fixed on the top of the micro electric telescopic cylinder 102 through the cylinder bottom shell 101.

[0028] When using a rapid sampling device for biological enzyme detection, first extend the sampling tube body 204 into the sampling cylinder 1, and insert the feed pipe 305 at the bottom of the sampling tube body 204 into the pipeline plug 202. When sampling is needed, the staff can directly open and close the micro pump body 201 to adjust the amount of sample drawn into the extraction tube 203. Moreover, after the sample is placed on the surface of the push plate 103, the push plate 103 and the sample can be driven up and down by the micro electric telescopic cylinder 102, thereby conveniently adjusting the height of the sample without the need to move the entire sampling tube. It is adjusted up and down. Since a spring 302 is provided in the first fixed cylinder 301, the elastic force of the spring 302 will drive the pressure plate 304 to move downward, thereby sealing the connection between the feed tube 305 and the sampling tube body 204. When the pipe plug 202 is inserted into the sampling tube body 204, the pipe plug 202 will press against the pressure plate 304 to move upward, thereby inputting the sample into the sampling tube body 204. When the sample input is completed, the pipe plug 202 is removed, and the elastic force will drive the pressure plate 304 to seal again, thereby realizing the self-sealing of the sampling tube.
