Description

Technical Field

[0001] This invention relates to the field of chemical instrument technology, and more specifically, to a shaking device and shaking method for chemical experiments. Background Technology

[0002] In biological, chemical, and medical experiments, shaking test tubes is a crucial step in sample mixing, reaction promotion, and homogenization. Currently, most commercially available test tube shaking devices employ a single shaking mode, such as horizontal rotation or left-right reciprocating shaking. However, these devices are limited in functionality and cannot simultaneously combine multiple shaking methods. Horizontal rotation is suitable for gentle mixing needs, but its effectiveness is limited for high-viscosity samples or scenarios requiring more vigorous mixing; while left-right shaking enhances mixing intensity, it struggles to ensure uniform sample dispersion. Due to the lack of devices capable of integrating multiple shaking modes, researchers often need to operate in steps or switch between different devices, which not only reduces experimental efficiency but may also affect the consistency and repeatability of mixing. Therefore, there is an urgent need to develop a composite test tube shaking device capable of simultaneously performing horizontal rotation and left-right shaking to meet the efficient mixing requirements of various experimental scenarios. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, one aspect of the present invention is to provide a shaking device for chemical experiments, the shaking device comprising a single-sided bending test tube rack, a shaking base plate, a hydraulic support frame, a rotating mechanism, and a base. Two sets of the single-sided bending test tube rack are symmetrically arranged, and the two sets of the single-sided bending test tube rack are fixedly mounted on the shaking base plate, with the two sets of the single-sided bending test tube rack positioned on both sides of the shaking base plate. Two sets of the hydraulic support frame are arranged, and the two sets of the hydraulic support frame are fixedly mounted below the shaking base plate, with the two sets of the hydraulic support frame positioned on both sides of the center of the shaking base plate. The two sets of the hydraulic support frame are fixedly mounted above the rotating mechanism, and the rotating mechanism is fixedly mounted on the base.

[0004] Preferably, the single-sided bending test tube rack includes a support frame, a fixing frame, a single-sided bending chain, a single test tube rack, and a first connecting rod. Three sets of support frames and two sets of single-sided bending chains are provided. The three sets of support frames are respectively fixedly connected to the two sets of single-sided bending chains. The three sets of support frames are respectively fixed to the sides and the middle of the two sets of single-sided bending chains. The fixing frame is fixedly installed on the upper single-sided bending chain. The single test tube rack is located on the non-bending side of the single-sided bending chain. The first connecting rod is located at the center below the lower single-sided bending chain and is fixedly installed on the rocking base plate.

[0005] Preferably, the fixing frame includes a first bending rod, a second bending rod, a baffle, a fixing crossbar, and a fixing buckle. The first bending rod is fixedly mounted on one end of the single-sided bending chain, and the fixing buckle is fixedly mounted on the other end of the single-sided bending chain. The second bending rod is hinged to the first bending rod. The baffle is mounted on the single-sided bending chain and is located on one side of the first and second bending rods. The height of the baffle is higher than that of the first bending rod and lower than the sum of the heights of the first and second bending rods. The fixing crossbar is hinged to the second bending rod, and the length of the fixing crossbar is the length from the first bending rod to the baffle when the single-sided bending chain is straightened.

[0006] Preferably, the single-sided curved chain includes inner links and outer links, and a plurality of inner links and outer links are provided. The number of inner links and outer links is the same and is odd. The inner links and outer links are connected by two nuts respectively.

[0007] Preferably, the number of individual test tube racks is the same as the number of inner and outer links.

[0008] Preferably, the rocking base plate includes a first rocking base plate, a second rocking base plate, and a central axis of the rocking base plate. The first rocking base plate and the second rocking base plate are hinged together by the central axis of the rocking base plate, and the first rocking base plate and the second rocking base plate are flipped upward and downward relative to the central axis of the rocking base plate.

[0009] Preferably, one of the lower end of the rocking base plate and the upper end of the hydraulic support frame is provided with a long hole extending forward and backward, and the other is provided with a second connecting rod, so that the rocking base plate and the corresponding hydraulic support frame are hingedly assembled.

[0010] Preferably, the base is made of heavy metal to ensure stability.

[0011] Preferably, the base includes an anti-slip rubber pad, which is fixedly disposed at the bottom of the base.

[0012] Another objective of this invention is to provide a shaking method for a shaking device used in chemical experiments, wherein the shaking method comprises the following steps:

[0013] S. Shaking mode selection: a. Left and right shaking mode, the fixed crossbar is locked in the fixed buckle to ensure that the test tube rack remains straight when bent on one side;

[0014] b. Horizontal rotation mode: Remove the fixed crossbar from the fixed buckle, rotate the second bending bar and the fixed crossbar to make the fixed crossbar vertically downward and the test tube horizontal. Bend the two ends of the single-sided bending test tube racks towards each other, and connect the two sets of single-sided bending test tube racks into a circle by nuts.

[0015] S. Test tube installation: Insert the test tubes to be shaken into the individual test tube rack of the single-sided bent test tube rack, ensuring that the test tubes are placed stably;

[0016] S. Start the device and shake: a. Left and right shaking mode, the hydraulic support frame drives the shaking base plate to swing up and down around the central axis of the shaking base plate, so that the single-sided bent test tube rack tilts left and right, which enhances the mixing effect;

[0017] b. Horizontal rotation mode: Activate the rotation mechanism to drive the shaking base plate and the single-sided bending test tube rack to rotate as a whole, so as to achieve uniform mixing in the horizontal direction;

[0018] S. Compound shaking mode: Simultaneously activates the rotating mechanism and hydraulic support frame, causing the test tube to swing left and right while rotating horizontally, improving mixing efficiency;

[0019] S. Height and angle adjustment: By adjusting the telescopic length of the hydraulic support frame, the tilt angle of the rocking base plate can be changed to adapt to different rocking intensity requirements;

[0020] S. Operation monitoring and maintenance: Regularly check the lubrication of the hydraulic support frame and rotating mechanism to ensure long-term stable operation.

[0021] The beneficial effects of this invention are as follows:

[0022] Multi-functional shaking mode: It offers three modes: left and right shaking, horizontal rotation, and combined shaking to meet different experimental needs. The left and right shaking mode enhances the mixing force, the horizontal rotation mode ensures uniform dispersion, and the combined mode combines the advantages of both to greatly improve the mixing efficiency.

[0023] Flexible and adjustable structural design: The single-sided bending test tube rack can be freely switched between straight (left and right rocking) or ring (horizontal rotation) form to adapt to different experimental scenarios. The hydraulic support frame can be driven independently or synchronously to adjust the rocking amplitude and tilt angle, and precisely control the mixing intensity.

[0024] Stable and reliable, anti-slip and anti-displacement: The base adopts a heavy-duty design and is equipped with anti-slip rubber pads to ensure that the equipment remains stable when operating at high speed, avoids vibration and displacement, and ensures experimental safety.

[0025] Efficient mixing enhances experimental efficiency: The combined shaking mode can simultaneously achieve rotation and oscillation, significantly shortening the mixing time. It is especially suitable for high-viscosity or difficult-to-mix samples, improving experimental repeatability and consistency.

[0026] Easy to operate and maintain: test tubes are easy to install, mode switching is intuitive, and no complicated adjustments are required.

[0027] This invention has a reasonable structure, multiple functions, and convenient operation. It is suitable for the high-efficiency mixing needs in biological, chemical, and medical experiments. While improving experimental efficiency, it also takes into account stability and reliability, and has significant practical value.
