Traditional shaking is mostly done manually, which significantly increases the workload for lab personnel. When extensive shaking is required, fatigue can reduce the force needed, leading to uneven mixing of samples and reagents and thus biased experimental data. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-5 As shown, this utility model is a laboratory reagent shaking device, including a base 1 and a first U-shaped frame 2. A support frame 3 and a support bar 4 are fixedly connected to the top of the base 1. A swinging shaking mechanism 5 is provided on the support frame 3. The swinging shaking mechanism 5 includes a fixed frame 51 fixedly connected to the support frame 3 and a first motor 52. The first motor 52 is a servo motor, which can precisely control the rotation angle and speed. The first motor 52 is electrically connected to an external power supply and is controlled by an external program. A connecting rod 53 is rotatably connected to the inner wall of the fixed frame 51. Two swing arms 54 are fixedly connected to the surface of the connecting rod 53. A connecting shaft 55 is fixedly connected to the inner wall of the two swing arms 54. A sliding sleeve 56 is slidably connected to the surface of the connecting shaft 55. A transmission shaft 57 is fixedly connected to the surface of the sliding sleeve 56. The output shaft of the first motor 52 passes through the fixed frame 51 and is fixedly connected to a transmission disk 58. By setting up the swinging shaking mechanism 5, the reagent tubes can be continuously shaken to be shaken evenly, which can replace manual labor, prevent uneven reagent mixing caused by human fatigue, and ensure the accuracy of experimental data.

[0024] The transmission disc 58 and the transmission shaft 57 are compatible. When the transmission disc 58 moves, it squeezes and drives the transmission shaft 57, allowing 57 to both slide on its inner wall and rotate on its own inner wall, forming a compound trajectory motion. The first U-shaped frame 2 is fixedly connected to the right end of the connecting rod 53.

[0025] A rotating shaft 6 is fixedly connected to the right side of the first U-shaped frame 2, and the rotating shaft 6 is rotatably connected to the support bar 4.

[0026] The inner wall of the first U-shaped frame 2 is fixedly connected to the second U-shaped frame 7. The inner wall of the second U-shaped frame 7 is provided with a clamping mechanism 8. By setting the clamping mechanism 8, the reagent tube can be quickly clamped and fixed in place, so that it will not fall off when shaken, and can be quickly removed.

[0027] The clamping mechanism 8 includes a second motor 81 fixedly connected to the inner wall of the second U-shaped frame 7, a limiting rod 82, and a transmission screw 83 rotatably connected to the inner wall of the second U-shaped frame 7. The transmission screw 83 has two sections of opposing-oriented threads on its surface. The second motor 81 is a servo motor, capable of precisely controlling the rotation angle and speed, and has an output shaft reversal function. Reversing the output shaft of the second motor 81 releases the clamping position. The second motor 81 is electrically connected to an external power source and controlled by an external program. A first gear 84 is fixedly connected to the surface of the output shaft of the second motor 81, and a second gear 85 is fixedly connected to the surface of the transmission screw 83. Two clamping strips 86 are threadedly connected to the surface of the transmission screw 83. The inner sides of the two clamping strips 86, where they clamp the reagent tubes, are made of silicone, providing elasticity to prevent rigid contact from damaging the reagent tubes. The inner walls of both clamping strips 86 have threaded grooves that mate with the adjacent threads. The first gear 84 and the second gear 85 mesh with each other, and both clamping strips 86 are slidably connected to the limiting rod 82.

[0028] The bottom of the base 1 is fixedly connected to four support feet 9 arranged in a rectangular array. The design of multiple support feet 9 ensures the stability of the equipment. The bottom of the support feet 9 is fixedly connected to a support base plate 10.

[0029] There are three second U-shaped frames 7, which are arranged in a linear array on the inner wall of the first U-shaped frame 2. The three clamping mechanisms 8 have the same structure.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] The working principle of this utility model is as follows: First, the reagent tube is lifted between the two clamping bars 86. Then, the second motor 81 is started, which drives the first gear 84 to rotate through the output shaft. When the first gear 84 rotates, it drives the second gear 85 to rotate through the transmission screw 83 inside the second U-shaped frame 7. When the transmission screw 83 rotates, it drives the two clamping bars 86 to move along the surface of the limiting rod 82 towards the opposite side, so that the two clamping bars 86 clamp the reagent tube. Then, the reagent tube is released by hand. Restart the first motor 52, which drives the transmission disk 58 to rotate through the output shaft. When the transmission disk 58 rotates, it squeezes and drives the transmission shaft 57, causing the transmission shaft 57 to slide back and forth on the surface of the connecting shaft 55 through the sliding sleeve 56. At the same time, it squeezes and drives the connecting shaft 55, causing the connecting shaft 55 to drive the connecting rod 53 to rotate back and forth in the inner wall of the fixed frame 51 through the two swing arms 54. This causes the connecting rod 53 to drive the first U-shaped frame 2 to rotate back and forth in the inner wall of the support bar 4 through the rotating shaft 6. This causes all the structures on the first U-shaped frame 2 and the reagent tubes that are clamped to swing back and forth, continuously shaking the reagent tubes.
