Description

Technical Field

[0001] This utility model relates to the field of vibrating centrifuge technology, specifically a spill-proof integrated vibrating centrifuge. Background Technology

[0002] The integrated shaking centrifuge is mainly used to shake or centrifuge the samples to be tested. By adding a certain amount of test solution to the sample and placing the test tube containing the sample in the integrated shaking centrifuge for shaking or centrifugation, the mixing effect of the test solution and the sample is improved.

[0003] A search revealed a patent, CN221714112U, which discloses a spill-proof integrated vibrating centrifuge. The centrifuge includes a horizontally positioned base with two symmetrically distributed side plates fixedly mounted on its upper surface. A cylinder is fixedly mounted on the inner wall of each side plate, and a round rod is slidably fitted onto the inner wall of each cylinder. The rod penetrates the cylinder and extends outwards from its end. A connecting platform is fixedly mounted between the two rods. A first spring is wound around the surface of the rod, and both ends of the spring are welded to the side wall of the connecting platform and the end face of the cylinder, respectively. Samples and solutions for sample testing can be stored in test tube bottles. Test tube holders allow for positioning and placement of the test tubes. A cap, fixed to the connecting plate, covers the test tube bottle and provides a secure fit. A second motor drives a shaft, causing the base to rotate, thus centrifuging the sample solution within the test tube bottle.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative documents describe placing test tubes between a test tube holder and a cap, and using a first or second motor to shake or centrifuge the samples within the test tubes. However, in reality, when shaking or centrifuging samples for testing, different test tubes need to be selected depending on the type or volume to be tested. The test tube holder and cap in the aforementioned comparative documents are only applicable to test tubes of the same model, thus reducing the applicability of the integrated shaking centrifuge. Therefore, there is an urgent need in the art to improve the integrated shaking centrifuge to overcome the shortcomings of the existing technology. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Please see Figures 1-7 A spill-proof integrated vibrating centrifuge includes a support frame 1, a rotating disk 2 rotatably connected to the upper part of the support frame 1, a support frame 3 fixedly installed on the upper part of the rotating disk 2, a first drive motor 4 for driving the rotating disk 2 to rotate fixedly installed on the inner top wall of the support frame 1, a sliding seat 5 slidably connected inside the support frame 3, a moving groove 6 adapted to the sliding seat 5 through the upper side of the support frame 3, a second drive motor 7 for driving the sliding seat 5 to vibrate back and forth in the moving groove 6 fixedly installed on the upper part of the rotating disk 2, a lower fixed base 9 fixedly installed on the upper side of the sliding seat 5, vertical support columns 8 fixedly installed at both ends of the lower fixed base 9, and an upper moving groove adapted to the lower fixed base 9 between the two support columns 8. The cover 10, the lower fixed base 9, and the upper movable cover 10 each have several placement slots 11 on their opposite sides. Two symmetrical and elastic clamping rings 12 are provided in each placement slot 11. Several first adjusting threaded rods 13, one end of which is rotatably connected to the side of the clamping ring 12, are threaded through and threaded to the sides of the lower fixed base 9 and the upper movable cover 10. A first limiting ring 14 is threaded to the side of the first adjusting threaded rod 13. The upper ends of the two support columns 8 are each provided with adjusting units 15 for adjusting the position of the upper movable cover 10. Two symmetrical clamping plates 20 are fixedly installed on the lower side of the sliding seat 5. A cam 21 located between the two clamping plates 20 is fixedly installed on the side of the output end of the second drive motor 7.

[0030] Specifically, when a sample needs to be mixed and tested by shaking and centrifugation, a quantitative amount of the detection solvent is dripped into a test tube containing the sample to be tested. The lower end of the test tube is inserted into the placement groove 11 on the lower fixed base 9. Two elastic clamping rings 12 limit and fix the lower end of the test tube. The upper movable cover 10 is adjusted downward by the adjustment unit 15. The placement groove 11 on the upper movable cover 10 is locked onto the upper part of the test tube. An elastic pad is provided on the top wall of the placement groove 11 on the upper movable cover 10. The upper movable cover 10 is fitted onto the upper end of several test tubes, and the upper part of the test tubes is pressed against the elastic pad on the top wall of the placement groove 11 on the upper movable cover 10 by the adjustment unit 15, sealing the upper end of the test tubes to prevent sample spillage during shaking or centrifugation, thus achieving the anti-spillage effect. At the same time, the first drive motor 4 is started, and the output of the first drive motor 4... The first end drives the rotating disk 2 to rotate, and the rotating disk 2 centrifuges the sample in the test tube. If it is necessary to shake and mix the sample, the second drive motor 7 is started. The output end of the second drive motor 7 drives the cam 21 to rotate. When the cam 21 rotates, it squeezes the clamping plate 20 and drives the sliding seat 5 to move back and forth in the moving groove 6 to achieve shaking and mixing of the test tube. When it is necessary to use test tubes of different thicknesses for mixing and testing, the first adjusting threaded rod 13 is rotated. When the first adjusting threaded rod 13 rotates, it drives the clamping ring 12 to move in the placement groove 11, thereby achieving the effect of adjusting the distance between the two clamping rings 12. This is suitable for clamping and fixing test tubes of different thicknesses. Then, the first limiting ring 14 is tightened to limit and fix the position of the first adjusting threaded rod 13, thereby improving the applicability of the overall shaking centrifuge.

[0031] As a technical optimization of this utility model, the adjustment unit 15 includes a second adjusting threaded rod 18 rotatably connected to the upper end of the support column 8, and sliding blocks 16 are fixedly installed at both ends of the upper movable cover 10. Sliding grooves 17 adapted to the sliding blocks 16 are opened on the opposing sides of the two support columns 8. The second adjusting threaded rod 18 passes through the sliding block 16 and is threadedly connected to the sliding block 16. A second limiting ring 19 is threadedly connected to the upper side of the second adjusting threaded rod 18.

[0032] Specifically, when it is necessary to adjust the upper movable cover 10, the second adjusting threaded rod 18 is rotated. When the second adjusting threaded rod 18 rotates, it drives the sliding block 16 to slide in the sliding groove 17. The two sliding blocks 16 drive the upper movable cover 10 to move up and down, thereby achieving the effect of adjusting the upper movable cover 10. Then, the second limiting ring 19 is tightened to limit and fix the second adjusting threaded rod 18.

[0033] As a technical optimization of this utility model, both ends of the sliding seat 5 are fixedly connected with guide columns 22 that penetrate the support frame 3, and the guide columns 22 are fitted with buffer springs 23 located between the end of the sliding seat 5 and the inner wall of the moving groove 6.

[0034] Specifically, when the sliding seat 5 reciprocates within the moving groove 6, the buffer spring 23 provides a certain elasticity, and the guide post 22 is used to limit the sliding seat 5 and at the same time prevent the buffer spring 23 from undergoing radial deformation.

[0035] As a technical optimization of this utility model, a number of rotatable balls 24 are embedded on the upper side of the support frame 1, and an arc groove 25 adapted to the balls 24 is opened on the lower surface of the rotating disk 2. When the rotating disk 2 rotates, the arc groove 25 rotates along the balls 24, reducing the frictional resistance encountered by the rotating disk 2 when it rotates.

[0036] As a technical optimization of this utility model, several suction cups 26 are fixedly installed on the lower side of the support frame 1. The suction cups 26 facilitate the stable installation of the entire device on the test table.

[0037] As a technical optimization of this utility model, chamfers 27 are provided on the upper part of the two opposing sides of the clamping rings 12. The chamfers 27 are used to guide the test tube when it is inserted into the placement groove 11, so as to facilitate the insertion of the test tube into the placement groove 11.

[0038] The first drive motor 4 and the second drive motor 7 mentioned above can both be purchased from the market. They are mature technologies and have been fully disclosed. Therefore, they will not be repeated in the specification. The first drive motor 4 and the second drive motor 7 are both equipped with power connection lines. They are electrically connected to the external main controller and 220V phase voltage (or chemical power source) through the power connection lines. The main controller can be a conventional known device such as a computer that plays a control role.
