Description

Technical Field

[0001] This utility model relates to a centrifuge for food testing, belonging to the field of centrifuge technology. Background Technology

[0002] Food safety has always been a top priority, requiring strict control at every step from production to sales to prevent substandard food from entering the market and harming people's health. Quality testing is essential during food production and inspection, and centrifuges, as commonly used equipment in food testing, play a crucial role. However, existing centrifuges can only maintain a single angle for testing and cannot adjust the test tubes.

[0003] The angle at which centrifugation is performed may affect the processing results of some samples, depending on the specific samples being processed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a centrifuge for food testing, which solves the problem that existing centrifuges can only maintain the same angle for testing and cannot adjust the test tubes.

[0005] The angle at which centrifugation is performed may lead to poor processing results for some samples when dealing with different samples.

[0006] The technical problem to be solved by this utility model is achieved by the following technical solution: A centrifuge for food testing includes a fixed cylinder with a vertically formed cavity structure. A support plate is fixedly installed at the opening of the cavity structure. A rotating disk is rotatably installed on the support plate. Several placement plates are hinged to the support plate. An adjusting rod is installed on one side of each placement plate. An installation block is hinged to the adjusting rod. A positioning plate is fixedly installed on the installation block. A positioning groove is opened on the placement plate. The positioning plate is slidably connected to the positioning groove. A moving block is radially slidably installed on the inner wall of the cavity structure. The moving block is fixedly connected to the adjusting rod. A transmission structure is provided on the inner wall of the cavity structure. The rotating disk drives the moving block to move through the transmission structure. The fixed cylinder is also provided with a driving element for driving the movement of the fixed cylinder.

[0007] By adopting the above technical solution, the transmission structure first moves the moving block via a rotating disk. Then, the moving block drives the adjusting rod to move. The adjusting rod is then hinged to the mounting block, causing the mounting block to rotate. The mounting block then drives the positioning plate to slide inside the positioning groove, thereby allowing the positioning plate to push the placement plate to adjust its angle. By adjusting the angle of the placement plate, a suitable centrifugation angle can be adjusted for test tube samples with different characteristics, avoiding the problem of poor processing results for some test tube samples due to a fixed angle. This is beneficial for subsequent detection and analysis, and improves detection accuracy.

[0008] The present invention is further configured such that: the transmission structure includes a rotating shaft fixedly connected to the rotating disk, one end of the rotating shaft extends into the interior of the cavity structure, a threaded rod is radially provided on the inner wall of the cavity structure, the threaded rod is threadedly connected to the moving block, and one end of the threaded rod away from the moving block is connected to the rotating shaft through a bevel gear set.

[0009] By adopting the above technical solution, the rotating disk drives the rotating shaft to rotate, and then the rotating shaft drives the threaded rod to rotate through the bevel gear set, and then the threaded rod drives the moving block to move.

[0010] The present invention is further configured as follows: a plurality of limiting grooves are formed on the rotating disk; a fixing block is fixedly set on the support plate; a guide groove is formed on the fixing block; a limiting rod is slidably set inside the guide groove; one end of the limiting rod extends to the outside of the guide groove and can be inserted into the limiting groove; a push plate is fixedly set on the limiting rod, and the push plate extends to the outside of the fixing block. A handle is fixedly set on the side of the rotating disk away from the fixing cylinder; a spring is fixedly set between the end of the limiting rod away from the limiting groove and the inner wall of the guide groove.

[0011] By adopting the above technical solution, the push plate drives the limiting rod to move away from the limiting groove within the guide groove. During the movement, the limiting rod compresses the spring, separating the limiting rod from the limiting groove, allowing the rotating disk to rotate. The rotating disk can be easily rotated using the handle. When the angle is adjusted to the appropriate angle, releasing the push plate causes the spring to reset and push the limiting rod towards the limiting groove, inserting it into the groove and limiting the rotation of the rotating disk. This prevents the rotating disk from rotating unexpectedly during centrifugation, thus affecting the accuracy of centrifugation testing.

[0012] The present invention is further configured such that: a shell is provided on the outside of the fixed cylinder, the shell is a hollow structure, the fixed cylinder is located inside the hollow structure, the hollow structure is provided with a one-way opening, and a cover plate is hinged to the one-way opening. A sealing element is provided between the cover plate and the shell.

[0013] By adopting the above technical solution, the shell encloses the fixed cylinder. The enclosed structure helps to maintain the relative stability of the environment around the fixed cylinder and ensures the stable performance of the device.

[0014] The present invention is further configured such that: the driving element includes a motor, the output end of the motor is connected to a transmission shaft, and the transmission shaft and the fixed cylinder are fixedly connected.

[0015] By adopting the above technical solution, the starting motor drives the transmission shaft to rotate, and then the transmission shaft drives the fixed cylinder to perform centrifugal motion.

[0016] The beneficial effects of this utility model are as follows: First, the rotating disk causes the transmission structure to move the moving block. Then, the moving block drives the adjusting rod to move. Next, the adjusting rod is hinged to the mounting block, causing the mounting block to rotate. Then, the mounting block drives the positioning plate to slide inside the positioning groove, thereby causing the positioning plate to push the placement plate to adjust the angle, thus achieving the angle adjustment of the placement plate. By adjusting the angle of the placement plate, a suitable centrifugation angle can be adjusted for test tube samples with different characteristics, avoiding the problem of poor processing effect of some test tube samples due to a fixed angle, which is beneficial to subsequent detection and analysis and improves detection accuracy.

[0023] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0024] like Figures 1 to 4As shown, a centrifuge for food testing includes a fixed cylinder 1, a cavity structure 2 extending axially from the fixed cylinder 1, a single-sided opening in the cavity structure 2 facing the extending direction, a support plate 3 fixedly mounted at the opening of the cavity structure 2, a rotating disk 4 rotatably mounted on the support plate 3, and a plurality of placement plates 5 hinged to the support plate 3. The plurality of placement plates 5 are arranged in a circumferentially at equal angles along the circumference of the fixed cylinder 1, and the end faces of the placement plates 5 are hinged to the support plate 3. The placement plates 5 are provided with placement slots 501 for placing reagents. The hinge end of the 5 is provided, and the placement groove 501 extends toward the side away from the hinge end. An adjusting rod 6 is provided on one side of several placement plates 5. An installation block 7 is hinged on the adjusting rod 6. A positioning plate 9 is fixedly provided on the installation block 7. A positioning groove 10 is provided on the placement plate 5. The positioning plate 9 and the positioning groove 10 are slidably connected. A moving block 8 is radially slidably provided on the inner wall of the cavity structure 2. The moving block 8 can extend to the outside of the fixed cylinder 1. The moving block 8 is fixedly connected to the adjusting rod 6. A transmission structure is provided on the inner wall of the cavity structure 2. A driving element for driving the movement of the fixed cylinder 1 is provided on the fixed cylinder 1.

[0025] like Figure 2 As shown, the transmission structure includes a rotating shaft 1011 fixedly connected to the rotating disk 4. One end of the rotating shaft 1011 extends into the interior of the cavity structure 2. A threaded rod 1012 is radially arranged on the inner wall of the cavity structure 2. The threaded rod 1012 is threadedly connected to the moving block 8. One end of the threaded rod 1012 away from the moving block 8 is connected to the rotating shaft 1011 through a bevel gear set. The bevel gear set includes a first gear fixedly arranged with the rotating shaft 1011, and a second gear fixedly arranged with one end of the threaded rod 1012. Transmission is achieved through the meshing of the first gear and the second gear.

[0026] like Figure 3As shown, a plurality of limiting grooves 1031 are radially opened on the rotating disk 4, and a fixing block 1032 is fixedly installed on the support plate 3. The fixing block 1032 is located on the radial side of the rotating disk 4. A guide groove 1033 is opened on the fixing block 1032. The guide groove 1033 is opened along the radial direction of the rotating disk 4. A limiting rod 1034 is slidably installed inside the guide groove 1033. The limiting rod 1034 reciprocates along the opening direction of the guide groove 1033. One end of the limiting rod 1034 extends to the outside of the guide groove 1033 and can be inserted into the limiting groove 1031. A push plate 1035 is fixedly installed on the limiting rod 1034. The push plate 1035 extends to the outside of the fixing block 1032. A handle 1041 is fixedly installed on the side of the rotating disk 4 away from the fixed cylinder 1. A spring 1042 is fixedly installed between the end of the limiting rod 1034 away from the limiting groove 1031 and the inner wall of the guide groove 1033. When the spring 1042 is at rest, it is not under force. At this time, the limiting rod 1034 is inserted into the limiting groove 1031 to limit the position of the rotating disk 4. When the spring 1042 is compressed, the limiting rod 1034 is separated from the limiting groove 1031, and the position limitation of the rotating disk 4 can be canceled.

[0027] like Figure 5 As shown, a housing 1051 is provided on the outside of the fixed cylinder 1. The housing 1051 is used to enclose the fixed cylinder 1 and maintain a good working environment. The housing 1051 is a hollow structure 1052, and the fixed cylinder 1 is located inside the hollow structure 1052. The hollow structure 1052 is provided with a one-way opening 1053, and a cover plate 1054 is hinged to the one-way opening 1053. A sealing element is provided between the cover plate 1054 and the housing 1051. The sealing element may include a sealing groove formed on the cover plate 1054, and a sealing strip is provided on the housing 1051. When the housing 1051 is connected to the cover plate 1054, the sealing strip and the sealing groove cooperate to form a seal.

[0028] like Figure 1 As shown, the driving element includes a motor 1061, which is located inside the hollow structure 1052. The output end of the motor 1061 is connected to a drive shaft 1062. The fixed cylinder 1 and the drive shaft 1062 rotate synchronously, and the drive shaft 1062 and the fixed cylinder 1 are fixedly connected.

[0029] First, the transmission structure moves the moving block 8 via the rotating disk 4. Then, the moving block 8 moves the adjusting rod 6. The adjusting rod 6 is then hinged to the mounting block 7, causing the mounting block 7 to rotate. The mounting block 7 then moves the positioning plate 9 to slide inside the positioning groove 10, thereby causing the positioning plate 9 to push the placement plate 5 to adjust its angle. By adjusting the angle of the placement plate 5, a suitable centrifugation angle can be adjusted for test tube samples with different characteristics, avoiding the problem of poor processing effect of some test tube samples due to a fixed angle. This is beneficial for subsequent detection and analysis and improves detection accuracy.

[0030] The rotating disk 4 drives the rotating shaft 1011 to rotate, and then the rotating shaft 1011 drives the threaded rod 1012 to rotate through the bevel gear set, and then the threaded rod 1012 drives the moving block 8 to move.

[0031] The push plate 1035 drives the limiting rod 1034 to move away from the limiting groove 1031 within the guide groove 1033. During the movement, the limiting rod 1034 compresses the spring 1042, separating the limiting rod 1034 from the limiting groove 1031, allowing the rotating disk 4 to rotate. The rotating disk 4 can be easily rotated using the handle 1041. When the angle is adjusted to a suitable angle, the push plate 1035 is released, and the spring 1042 resets, pushing the limiting rod 1034 towards the limiting groove 1031, causing the limiting rod 1034 to insert into the interior of the limiting groove 1031, thus limiting the rotating disk 4 and preventing accidental rotation of the rotating disk 4 during centrifugation, which would affect the accuracy of centrifugation testing.

[0032] The housing 1051 encloses the fixed cylinder 1. The enclosed structure helps maintain the relative stability of the environment around the fixed cylinder 1 and ensures the stable performance of the device.

[0033] The motor 1061 is started to drive the transmission shaft 1062 to rotate, and then the transmission shaft 1062 drives the fixed cylinder 1 to perform centrifugal motion.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model.
