Description

Technical Field

[0001] The utility model belongs to the field of laboratory mixing equipment, and more specifically, relates to a vortex oscillator. Background Art

[0002] Vortex oscillators are small mixing devices commonly used in scientific research laboratories in chemical, food, biological, and medical fields, used to mix various reagents, mixed solutions, and the like. Patent publication number CN211159539U discloses a vortex oscillator, comprising a base and an oscillating disk. The base is provided with a motor, which is in transmission connection with the oscillating disk. The oscillating disk is evenly arranged with multiple sample slots. The outer side of the sample slot is provided with an arc seat 1, and the inner side is provided with a chute connected to the upper portion. The chute is provided with a shaft body. The shaft body is provided with an arc seat 2, a limit spring, and a limit block in sequence from the outside to the inside. The inner wall of the chute is provided with an annular limit member between the limit spring and the limit block. When using this patented technology, the multiple arc seats 2 can be pulled inward at the same time. At this time, the arc seats 2 move inward, and the limit spring is compressed. Then, a sample tube is placed in the sample slot. The arc seat 2 is released, and the limit spring resets and drives the arc seat 2 to move outward, compressing the upper part of the sample tube. Therefore, when securing or removing each sample tube, it is necessary to manually pull the arc seat 2 to release the low pressure exerted by the arc seat 2 on the sample tube, thereby facilitating the insertion or removal of the sample tube. This patented technology has the following drawbacks: when the sample tube is thick, the limit spring needs to be pulled to a greater extent, making it difficult to remove or insert the sample tube from the sample slot; and when the sample tube is thin, the return spring has a greater extension, which does not provide a strong enough low pressure on the sample tube, making it impossible to secure the sample tube, resulting in poor versatility of the device.

[0033] like Figure 1-2 As shown, the utility model provides a vortex oscillator, comprising a base 1 for mounting a motor 2, an oscillating plate 3 for oscillating a sample, and a motor 2 for driving the oscillating plate 3 to vibrate. The oscillating plate 3 is provided with a plurality of sample slots 4 and a sample clamping structure for clamping and fixing a sample tube in the sample slots 4. The plurality of sample slots 4 are arranged in a circular array on the oscillating plate 3. The sample clamping structure comprises:

[0034] an abutment structure, which is arranged on the upper surface of the oscillating plate 3 and arranged along the radial direction of the oscillating plate 3;

[0035] A compression structure, which is arranged in the middle of the oscillating plate 3;

[0036] When the pressing structure is pressed downward, the pressing structure abuts against the abutting structure and pushes the abutting structure to move toward the sample slot 4 to clamp and fix the sample tube in the sample slot 4 .

[0037] In the present technical solution, the motor 2 is installed on the base 1 using conventional technical means, and the oscillating disk 3 is connected to the motor 2 using conventional technical means. The oscillating disk 3 is a disc-shaped structure, and the sample slots 4 are evenly distributed on the oscillating disk 3. The abutment structure can be an abutment rod, one end of which can be moved into the sample slot 4, so that when the abutment rod is pressed by the clamping structure, the abutment rod moves toward the sample slot 4 to clamp the sample tube in the sample slot 4. When the clamping structure moves upward, the abutment rod no longer presses the sample tube in the sample slot 4, and the sample tube can be taken out of the sample slot 4 relatively easily. When the utility model presses the clamping structure downward, it can simultaneously drive the abutment structure to move, thereby fixing the sample tube at the same time.

[0038] In another technical solution, the abutment structure includes:

[0039] An abutment groove is provided on the upper surface of the oscillating plate 3, and the abutment groove is provided along the radial direction of the oscillating plate 3;

[0040] The abutment member is slidably disposed in the abutment groove, and one end of the abutment member can slide into the sample groove 4, and the other end of the abutment member can slide into the pressing structure.

[0041] In this technical solution, the cross section of the abutment groove can be circular or rectangular, and the abutment groove is connected to the sample groove 4 so that the abutment member can penetrate into the sample groove 4. The abutment member can be an abutment rod, and its cross section is correspondingly set to be circular or rectangular.

[0042] In another technical solution, the abutment member includes a first abutment rod 9, a spring 13, and a second abutment rod 11, with the first abutment rod 9 and the second abutment rod 11 respectively disposed at both ends of the spring 13. When the compression structure is pressed downward, the second abutment rod 11 pushes the spring 13 toward the sample tank 4, and the spring 13 pushes the first abutment rod 9 toward the sample tank 4. When the first abutment rod 9 abuts the sample tube, as the compression structure continues to press downward, the spring 13 is compressed, thereby achieving the abutment and fixation of the first abutment rod 9 against the sample tube. By providing the spring 13, sample tubes of different models and specifications can be placed in the sample tank 4 during the oscillation process of the same batch.

[0043] In another technical solution, two clamping plates 10 are provided at the upper end of the sample well 4. The clamping plates 10 have an arcuate structure and are arranged opposite each other. One clamping plate 10 is fixedly connected to the sample well 4, and the other clamping plate 10 is fixedly connected to the first abutting rod 9. The arcuate structure of the clamping plates 10 increases the clamping area for the sample tube and enhances the stability of the abutment fixation. A guide plate can also be provided above the clamping plates 10 to facilitate the insertion of the sample tube into the sample well 4.

[0044] In another technical solution, a limiting protrusion 12 is provided on the second abutting rod 11, and a limiting groove is provided on the wall of the abutting groove, in which the limiting protrusion 12 is slidably disposed. By providing the limiting protrusion 12 and the limiting groove, the distance that the second abutting rod 11 can enter the clamping structure is limited, thereby preventing it from excessively penetrating into the fixing groove 8 in the clamping structure and blocking the fixing block 7 in the clamping structure from entering the fixing groove 8.

[0045] In another technical solution, a rubber layer is provided on the inner side of the clamping plate 10. The rubber layer can increase the tightness of the abutment between the clamping plate 10 and the sample tube.

[0046] In another technical solution, the compression structure includes:

[0047] A fixing groove 8 is provided in the middle of the oscillating plate 3;

[0048] A fixing rod 5 is provided in the middle of the fixing groove 8 and is provided with an external thread;

[0049] The fixing block 7 is a truncated cone-shaped structure. A through hole is provided in the middle of the fixing block 7. The fixing block 7 is slidably sleeved on the outer side of the fixing rod 5.

[0050] a fixing nut 6, which is arranged above the fixing block 7 and is threadedly connected to the fixing rod 5;

[0051] The lower diameter of the fixing block 7 is smaller than the upper diameter. When the fixing block 7 moves downward along the fixing rod 5 , the fixing block 7 pushes the abutment member to move outward to fix the sample tube.

[0052] In this technical solution, the middle of the bottom of the oscillating disk 3 is connected to the motor 2, the cross-section of the fixing groove 8 is circular, the cross-section of the fixing rod 5 is circular, and the diameter of the fixing rod 5 is smaller than the diameter of the fixing groove 8.

[0053] The method of using this technical solution is as follows: place the sample tube in the sample slot 4, press down the fixing block 7 with force to make the first abutment rod 9 tightly abut against the sample tube, and rotate the fixing nut 6 downward along the fixing rod 5 to fix the fixing block 7, thereby fixing the sample tube.

[0054] In another technical solution, a rolling wheel is provided at one end of the abutting member abutting against the fixing block 7. By providing the rolling wheel, the fixing block 7 is pressed downward better.

[0055] The present invention is used as follows: Place the sample tube in the sample slot 4, press down the fixing block 7 to secure the sample tube tightly with the clamping plate 10, secure the fixing block 7 with the fixing nut 6, start the motor 2, and complete the oscillation mixing of the sample in the sample tube. After the oscillation mixing is completed, turn off the motor 2, loosen the fixing nut 6, and lift the fixing block 7 upward until the first abutment rod 9 contacts the sample tube, allowing the sample tube to be easily removed.

[0056] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
