Description

Technical Field

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

[0002] A centrifuge is a machine that uses centrifugal force to separate the components of a mixture of liquids and solid particles or liquids. Centrifuges are mainly used to separate solid particles from liquids in suspensions, or to separate two types of solid particles with different densities in emulsions. They utilize the different settling velocities of solid particles of different densities or sizes in a liquid. Some sedimentation centrifuges can also classify solid particles according to density or particle size.

[0003] The existing centrifuges used for testing health food have a fixed size tube positioning sleeve, which cannot be used with test tubes of different sizes. When using them, the tube positioning sleeve needs to be replaced, which is a cumbersome and time-consuming process, resulting in a decrease in the testing efficiency of health food.

[0004] To overcome the above-mentioned defects, the prior art (Chinese patent publication number: CN222678372U, publication date: 2025-03-28) discloses a centrifuge for testing health food, including a centrifuge chamber. A rotating shaft is rotatably connected inside the centrifuge chamber. Multiple evenly distributed limiting mechanisms are provided on the outer wall of the rotating shaft. The limiting mechanism includes an outer ring fixedly connected to the outer wall of the rotating shaft. An inner ring is rotatably connected inside the outer ring. Multiple evenly distributed rotating rods are provided above the outer ring and the inner ring. The rotating rods are rotatably connected to the outer ring and the inner ring through vertical rods. When the lead screw rotates, the bidirectional lead screw, in conjunction with two movable plates, drives two connecting plates to move closer to each other, thereby driving the inner ring to rotate. When the inner ring rotates, the rotating rods rotate through the two vertical rods, causing one end of the rotating rod to move towards the center of the inner ring, thereby driving the multiple limiting rods to move closer to each other, so that the multiple limiting rods abut against the outer wall of the test tube, thereby limiting the test tube to accommodate test tubes of different sizes.

[0005] While the above design can solve the aforementioned problems, it is inefficient when the test tubes need to be stably clamped, requiring multiple manual fixations, which increases the processing time of the equipment and makes it impossible to test food more quickly and conveniently. At the same time, the existing design is too complicated and lacks rotational stability when high-speed centrifugation is required. Long-term use will cause the internal connections of the equipment to loosen, affecting its service life. Utility Model Content

[0006] The purpose of this utility model is to provide a centrifuge for testing health food, in order to solve the problems mentioned in the background art, which are that the efficiency is low when the test tubes need to be stably clamped, multiple manual fixation is required, which increases the processing time of the equipment and makes it impossible to test food more quickly and conveniently. At the same time, when high-speed centrifugation is required, the existing design is too complicated and the rotational stability is insufficient. Long-term use will cause the internal connections of the equipment to loosen, affecting the service life.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a centrifuge for testing health food, comprising a processing stabilizing box, wherein a centrifugal hollow tube is installed inside the processing stabilizing box, and an elastic sliding mechanism for supporting the placement of the stabilizing tube is installed inside the centrifugal hollow tube. The elastic sliding mechanism includes a semi-circular abutment rod, the bottom of which is fixedly installed on the inner surface of the centrifugal hollow tube. A transverse sliding frame is installed on the upper surface of the centrifugal hollow tube, and a compression stabilizing plate is installed inside the transverse sliding frame. A downward pressure limiting frame is installed on the inner surface of the processing stabilizing box, and an engagement sliding mechanism for rotating the bottom stabilizing plate is installed on the inner surface of the downward pressure limiting frame.

[0008] Furthermore, the meshing sliding mechanism includes a drive motor, which is fixedly mounted on the lower surface of the processing stabilizing box. A first meshing gear is mounted on the outer surface of the output end of the drive motor, and the lower end of the centrifugal hollow tube penetrates the lower surface of the processing stabilizing box.

[0009] Furthermore, a second meshing gear is installed on the lower outer surface of the centrifugal hollow tube, and the first meshing gear meshes with the second meshing gear. An outer hollow ring is installed on the outer surface of the centrifugal hollow tube, and the lower surface of the outer hollow ring slides in contact with the inner surface of the processing stabilizing box.

[0010] Furthermore, the semi-circular abutment rod corresponds to the inner part of the compression stabilizing plate and the opening of the stabilizing tube, and an extension clamping spring is installed on the top outer surface of the centrifugal hollow tube. The end of the extension clamping spring is fixedly installed to the back of the compression stabilizing plate, and the compression stabilizing plate slides along the interior of the transverse sliding frame.

[0011] Furthermore, high-strength connecting ropes are installed on the left and right sides of the extrusion stabilizing plate, and an opening and closing rotating cover is installed at the opening of the processing stabilizing box. A pressing fixing rod is installed on the inner surface of the opening and closing rotating cover, and the end of the moving trajectory of the pressing fixing rod will abut against the top of the high-strength connecting rope.

[0012] Furthermore, the centrifugal hollow tube and the semi-circular contact rod are designed as a single unit, and the opening and closing rotating cover is rotatably installed inside the processing stabilizing box. The back of the extrusion stabilizing plate contacts the top of the extension clamping spring to form an elastic structure, and the end of the high-strength connecting rope fixes the two sides of the four sets of extrusion stabilizing plates accordingly.

[0013] Furthermore, the outer hollow ring slides along the inside of the downward limiting frame, and the outer surface of the first meshing gear contacts the outer surface of the second meshing gear to form a meshing structure. The centrifugal hollow tube and the outer hollow ring are designed as an integral unit, and the bottom stabilizing plate is nested and fixedly installed on the inner bottom surface of the centrifugal hollow tube.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When the centrifuge for testing health food needs to perform a stable clamping operation on the test tube, the test tube is directly placed inside the stable tube. At this time, the semi-circular contact rod and the compression stabilizing plate will initially clamp the upper end of the test tube. Then, the rotating cover is rotated downwards to make the pressing fixing rod press down the high-strength connecting rope accordingly. The compression stabilizing plate and the extension clamping spring will make the clamping of the test tube more stable. This design makes the clamping operation of the test tube more efficient and allows for quick and convenient start-up of the equipment for food testing.

[0015] Furthermore, when it is necessary to perform high-speed rotation of the stabilizing tube, the drive motor is directly started and the second meshing gear is driven through the first meshing gear. At this time, the centrifugal hollow tube will be driven to rotate continuously in a circular motion. At the same time, the bottom stabilizing plate will stabilize the end of the centrifugal hollow tube. This design makes the high-speed centrifugation process more stable and faster, and will not cause the internal connections of the equipment to loosen, thereby improving the service life of the equipment.

[0016] Furthermore, the joints between the semi-circular contact rod and the extrusion stabilizing plate are both designed in a semi-circular shape, which can stably clamp the top of the test tube from front to back. In addition, the high-strength connecting ropes fix the four sets of extrusion stabilizing plates on both sides, making the equipment more convenient to use. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1 , Figure 3 The present invention provides the following technical solution: a centrifuge for testing health food, comprising a processing stabilizing box 1, a centrifugal hollow tube 7 installed inside the processing stabilizing box 1, an elastic sliding mechanism for supporting a placed stabilizing tube 8 installed inside the centrifugal hollow tube 7, the elastic sliding mechanism comprising a semi-circular abutment rod 9, the bottom of the semi-circular abutment rod 9 being fixedly installed on the inner surface of the centrifugal hollow tube 7, a transverse sliding frame 14 installed on the upper surface of the centrifugal hollow tube 7, a compression stabilizing plate 10 installed inside the transverse sliding frame 14, a downward pressure limiting frame 16 installed on the inner surface of the processing stabilizing box 1, and an engagement sliding mechanism for rotating the bottom stabilizing plate 13 installed on the inner surface of the downward pressure limiting frame 16.

[0026] like Figure 1 , Figure 3 and Figure 4The technical solution shown addresses the problem of low efficiency and multiple manual fixations required for stable clamping of test tubes, which increases processing time and hinders faster and more convenient food testing. It discloses that the semi-circular contact rod 9 corresponds to the opening of the stabilizing tube 8, and an extension clamping spring 12 is installed on the top outer surface of the centrifugal hollow tube 7. The end of the extension clamping spring 12 is fixedly installed to the back of the stabilizing plate 10, and the stabilizing plate 10 slides along the interior of the transverse sliding frame 14, thus stabilizing the test tube. High-strength connecting ropes 15 are installed on the left and right sides of plate 10, and an opening and closing rotating cover 2 is installed at the opening of the processing stabilizing box 1. A pressing fixing rod 6 is installed on the inner surface of the opening and closing rotating cover 2, and the end of the moving trajectory of the pressing fixing rod 6 will abut against the top of the high-strength connecting rope 15. The centrifugal hollow tube 7 and the semi-circular abutting rod 9 are integrated into one piece, and the opening and closing rotating cover 2 is rotatably installed inside the processing stabilizing box 1. The back of the extrusion stabilizing plate 10 contacts the top of the extension clamping spring 12 to form an elastic structure, and the end of the high-strength connecting rope 15 fixes the two sides of the four sets of extrusion stabilizing plates 10 accordingly.

[0027] When a stable clamping operation is required for the test tube, the test tube is directly inserted into the interior of the stabilizing tube 8. At this time, the outside of the test tube will abut against the semi-circular abutment rod 9 fixedly installed on the bottom surface of the centrifugal hollow tube 7, and the other side of the test tube will abut against the inner surface of the compression stabilizing plate 10. As the inside of the compression stabilizing plate 10 is abutted, the compression stabilizing plate 10 will slide in the opposite direction, and the sliding of the compression stabilizing plate 10 will be limited to sliding along the interior of the transverse sliding frame 14 fixedly installed on the upper surface of the centrifugal hollow tube 7, making the equipment more stable. At the same time, as the compression stabilizing plate 10 slides backward, it will abut against the extension clamping spring 12 fixed to each other on the back, thus causing it to contract. The other end of the clamping spring 12 is fixedly installed on the top of the centrifuge hollow tube 7, so the extension clamping spring 12 will vertically retract accordingly. After the test tube is initially inserted and stabilized, the opening and closing rotating cover 2 is rotated downward along the opening of the processing stabilizing box 1. This causes the opening and closing rotating cover 2 to synchronously drive the downward pressing fixing rod 6 fixedly installed on the inner surface downward. The downward pressing of the downward pressing fixing rod 6 will abut against the top of the high-strength connecting rope 15 and squeeze it downward accordingly. Since the end of the high-strength connecting rope 15 is fixedly installed on both sides of the compression stabilizing plate 10, the four sets of compression stabilizing plates 10 will move inward as the downward pressing work is carried out. During this process, the test tube will be stably clamped due to the corresponding abutment between the semi-circular abutting rod 9 and the compression stabilizing plate 10.

[0028] Example 2: Figure 2 , Figure 5 and Figure 6The technical solution shown addresses the problems of existing designs being overly complex and lacking rotational stability during high-speed centrifugation, leading to loosening of internal connections and reduced lifespan after prolonged use. The solution discloses a meshing sliding mechanism including a drive motor 3, which is fixedly mounted on the lower surface of the processing stabilizing box 1. A first meshing gear 4 is mounted on the outer surface of the output end of the drive motor 3. The lower end of the centrifugal hollow tube 7 penetrates the lower surface of the processing stabilizing box 1, and a second meshing gear 5 is mounted on the outer surface of the lower end of the centrifugal hollow tube 7. The first meshing gear 4 and the second meshing gear 5 mesh with each other. An outer hollow ring 11 is installed on the outer surface of the centrifugal hollow tube 7, and the lower surface of the outer hollow ring 11 slides against the inner surface of the processing stabilizing box 1. The outer hollow ring 11 slides along the inside of the lower pressure limiting frame 16, and the outer surface of the first meshing gear 4 contacts the outer surface of the second meshing gear 5 to form a meshing structure. The centrifugal hollow tube 7 and the outer hollow ring 11 are designed as an integral piece, and the bottom stabilizing plate 13 is nested and fixedly installed on the inner bottom surface of the centrifugal hollow tube 7.

[0029] When centrifugal hollow tube 7 needs to be rotated as a whole for centrifugation, the drive motor 3 fixedly mounted on the lower surface of the processing stabilizer box 1 is started directly. The start of the drive motor 3 will drive the first meshing gear 4 fixedly mounted on the outer surface of the output end to rotate accordingly. During the rotation of the first meshing gear 4, it will mesh with the second meshing gear 5 in contact with the outer surface, thus driving it. Since the second meshing gear 5 is fixedly mounted on the outer surface of the end of the centrifugal hollow tube 7, the centrifugal hollow tube 7 will rotate in a limited circumferential motion along the bottom surface of the processing stabilizer box 1, thereby driving the stabilizer tube 8 and the test tube inside to rotate. When the centrifugal hollow tube 7 rotates, the outer hollow ring 11 fixedly installed on the top outer surface will rotate synchronously. The rotation of the outer hollow ring 11 will be limited and slid along the inside of the pressure limiting frame 16 fixedly installed on the bottom surface of the processing stabilizing box 1. Since the top of the inner surface of the pressure limiting frame 16 is in contact with the upper surface of the outer hollow ring 11, the overall rotation of the centrifugal hollow tube 7 is more stable. At the same time, the rotation of the centrifugal hollow tube 7 will drive the bottom stabilizing plate 13 nested inside. Since the installation position of the bottom stabilizing plate 13 clamps and nests the four sets of stabilizing tubes 8, the equipment is more stable when performing centrifugal rotation operation.
