Description

Technical Field

[0001] The present invention relates to a dynamic shaking table that can evenly mix or disperse liquid in a test tube, and belongs to the technical field of shaking table equipment. In particular, it relates to a dynamic shaking table that drives an eccentric wheel to rotate by a dual-axis motor placed in a bin so that a vertical frame slides back and forth under the cooperation of a guide component, and drives a second connecting rod to rotate by starting a rotating motor, and drives the test tube rack to flip through a swing frame and a first connecting rod, thereby mixing or dispersing the liquid in the test tube. Background Art

[0002] In laboratories and industrial production, it is often necessary to mix the liquid in the test tube. Existing liquid mixing shaker devices have many problems. In terms of mixing function, existing devices can often only achieve single-dimensional movement, making it difficult to fully and efficiently mix the liquid in the test tube. For example, they can only simply shake horizontally or oscillate vertically, resulting in uneven liquid mixing, affecting the accuracy of experimental results and the quality of industrial products. In terms of performance assurance, most traditional shakers do not fully consider the protection of the motor and lack effective buffering and shock absorption measures. The motor is susceptible to large impact forces during operation, which accelerates motor loss. At the same time, the heat dissipation design is poor, and the heat generated by the long-term operation of the motor cannot be dissipated in time, causing the motor to overheat. This not only shortens the service life of the motor, but also reduces the reliability of the shaker operation, posing a safety hazard.

[0003] Publication number CN221501046U discloses an adjustable constant temperature culture oscillator, including a box, a control panel, a heater, an air conditioning hole, an oscillating device, and a positioning structure. The top of the box is equipped with a control panel, two heaters are installed on the left and right sides of the inner wall of the box, air conditioning holes are installed on the front and back sides of the inner wall of the box, an oscillating device is installed on the bottom of the inner wall of the box, and a positioning structure is installed on the oscillating device. A positioning structure is provided, and a reagent bottle is clamped by clamps 1 and 2. The rubber interlayer on clamps 1 and 2 is used to shake the reagent bottle, and the shaking effect of the water bath shaker can be improved by springs 1 and 2. Publication No. CN117586853A discloses a constant temperature mixing shaker, comprising: a constant temperature box, the constant temperature box having a rectangular structure, and a rectangular box cover that is inserted and installed on the top opening of the constant temperature box; a horizontally arranged bed frame that is rotatably mounted on the bottom plate of the constant temperature box, and four horizontal trays for carrying culture dishes welded to the tops of four vertical support shafts; two longitudinal support shafts welded to the interior of the bed frame in a left-right symmetrical manner, and four connecting rods are symmetrically connected to the front and rear ends of the two longitudinal support shafts in a co-symmetrical rotation. Due to the parallel lifting motion of the parallelogram rocking mechanism during the rocking process, the culture dishes and the liquid level of the culture fluid therein can be kept relatively horizontal. However, the above-mentioned oscillator or shaker can only achieve single-dimensional motion, making it difficult to fully and efficiently mix the liquid in the test tube. At the same time, there is a lack of effective buffering and shock absorption measures, and the motor is easily subjected to large impact forces during operation, which accelerates motor wear.

The flip stand (3) is composed of two vertical rods and two U-shaped rods. The top ends of the two vertical rods are fixedly connected to the top plate (2). The U-shaped rods are placed horizontally. The two ends of the first U-shaped rod are respectively fixedly connected to the side surfaces of the middle positions of the two vertical rods. The two ends of the second U-shaped rod are respectively fixedly connected to the side surfaces of the bottom ends of the two vertical rods. The first fixed block (12) is fixedly placed on the top plate (2), and a limit axis is fixedly placed on the side of the first fixed block (12). One end of the swing frame (9) is sleeved on the limiting shaft of the first fixed block (12) and is rotatably connected to the limiting shaft of the first fixed block (12). The second fixing block (13) is fixedly placed on the first U-shaped rod. The two ends of the connecting shaft (15) are respectively placed on both sides of the second fixed block (13), and the connecting shaft (15) is rotatably connected to the second fixed block (13). The first connecting rod (16) is placed on one side of the second fixed block (13), and one end of the first connecting rod (16) is fixedly connected to one end of the connecting shaft (15). A first sliding block (17) is disposed on the side surface of the first connecting rod (16) near the other end, and the first sliding block (17) passes through the swing frame (9). The test tube rack (1) is placed on the other side of the second fixed block (13). The test tube rack (1) has a through hole near the middle. The other end of the connecting shaft (15) passes through the through hole of the test tube rack (1) and is fixedly connected to the test tube rack (1). The test tube rack (1) is evenly provided with a plurality of test tube insertion slots (14). The third fixing block (18) is fixedly placed on the second U-shaped rod. The second connecting rod (20) is rotatably connected to the third fixed block (18) through a rotating shaft near one end. The rotating motor (19) is fixedly placed on the stand (8), the motor shaft of the rotating motor (19) is fixedly connected to the second connecting rod (20), and the rotating shaft between the second connecting rod (20) and the third fixed block (18) is coaxially arranged with the motor shaft of the rotating motor (19). A second sliding block (21) is disposed on the side of the second connecting rod (20) near the other end. The second sliding block (21) passes through the swing frame (9). When in use, the test tube is inserted into the test tube insertion slot (14) of the test tube rack (1). The dual-axis motor in the placement chamber (11) is started, and the dual-axis motor drives the eccentric wheel (10) connected thereto to rotate. Since the center of gravity of the eccentric wheel deviates from its rotation center, an unbalanced centrifugal force is generated during the rotation process. Under the centrifugal force generated by the rotation of the eccentric wheel (10), the placement chamber (11) slides up and down under the guidance of the support rod (22). The buffer spring (23) plays a buffering and shock-absorbing role, alleviating the effect of the eccentric wheel (10) on the motor shaft of the dual-axis motor, and also making the movement of the placement chamber (11) more stable. The stand (8) is connected to the sliding groove on the base (7) by the sliding rib. Under the centrifugal force generated by the rotation of the eccentric wheel (10), the stand (8) is driven to move. At the same time, the first guide rod (5) and the return spring (6) in the guide assembly are pressed against the stand (8) ) plays a guiding and resetting role. When the stand (8) moves, the return spring (6) will generate elastic force after being stretched or compressed, so that the stand (8) can slide back and forth. After starting the rotary motor (19), the second connecting rod (20) is driven to rotate around the axis. When the second connecting rod (20) rotates, the second sliding block (21) slides in the swing frame (9), thereby driving the swing frame (9) to swing around the limit axis of the first fixed block (12). The first sliding block (17) slides in the swing frame (9), causing the first connecting rod (16) to reciprocate around the connecting shaft (15) on the second fixed block (13). When the first connecting rod (16) reciprocates around the connecting shaft (15), it drives the test tube rack (1) and the test tube inserted in the test tube insertion slot (14) to reciprocate, thereby achieving mixing of the liquid in the test tube; Example 2

[0011] The difference between this embodiment and embodiment 1 is that a shock-absorbing pad (24) is provided at the bottom end of the base (7). When in use, the shock-absorbing pad (24) can not only reduce noise but also protect the rocking table itself and the plane on which the rocking table is placed. During the vibration process generated by the operation of the rocking table, the shock-absorbing pad (24) can avoid friction damage caused by rigid contact between the base (7) and the placement plane, thereby extending the service life of the rocking table base (7) and preventing problems such as wear and deformation caused by long-term friction that affect the stability of the equipment. It also protects the placement plane and prevents it from being scratched or damaged. Example 3

[0012] The difference between this embodiment and embodiment 1 is that the side surface of the test tube insertion slot (14) is glued to the outer ring surface of the anti-slip strip (25), and the anti-slip strip (25) is made of rubber. When the test tube is inserted into the test tube insertion slot (14), the anti-slip strip (25) can fit tightly against the outer wall of the test tube, and effectively prevent the test tube from sliding due to shaking and vibration caused by the movement of the shaking table by using its large friction force, thereby ensuring that the test tube is always in a stable placement state during the operation of the shaking table. The stand (8) is placed on the base (7), and a sliding rib is provided on the top surface of the stand (8). The stand (8) is slidably connected to the base (7) by the sliding rib in conjunction with the sliding groove, thereby providing guidance and support for the sliding of the stand (8), thereby ensuring the stability and accuracy of the stand (8) during movement. Each support rod (22) corresponds to two buffer springs (23), and the buffer springs (23) are respectively connected to the bottom surface and top surface of the stand (8) and the bottom surface and top surface of the placement bin (11), which can effectively buffer and reduce shock, relieve the force of the eccentric wheel (10) on the motor shaft of the dual-axis motor, protect the motor, and make the movement of the placement bin (11) more stable, reducing the impact on the entire rocking bed structure; Each of the dual-axis motors corresponds to two eccentric wheels (10), and the eccentric wheel (10) axle passes through the placement chamber (11) and is fixedly connected to the motor shaft of the dual-axis motor. The centrifugal force generated by the rotation of the eccentric wheel (10) is the power source for the placement chamber (11) to slide up and down and the stand (8) to move. By reasonably designing the parameters and number of the eccentric wheels (10), the shaking amplitude and frequency of the shaking table can be accurately controlled to meet the requirements of different experiments for liquid mixing; The return spring (6) is wound around the first guide rod (5) and is located between the stand (8) and the stand plate (4). When the stand (8) moves under the centrifugal force of the eccentric wheel (10), the return spring (6) generates elastic force after being stretched or compressed, so that the stand (8) can slide back and forth, playing a role of reset and buffering, thereby ensuring the stability and reliability of the stand (8) during the movement. One end of the first connecting rod (16) is fixedly connected to one end of the connecting shaft (15), and a first sliding block (17) is provided on the side near the other end. The first sliding block (17) is designed to pass through the swing frame (9). When the swing frame (9) swings, the first sliding block (17) slides in the swing frame (9), causing the first connecting rod (16) to reciprocate around the connecting shaft (15), thereby driving the test tube rack (1) to reciprocate, realizing the flipping movement of the test tube, and improving the working efficiency and reliability of the shaking table; A second sliding block (21) is provided on the side of the second connecting rod (20) near the other end. The second sliding block (21) is designed to pass through the swing frame (9). When the second connecting rod (20) rotates, the second sliding block (21) slides in the swing frame (9), driving the swing frame (9) to swing around the limit axis of the first fixed block (12), thereby realizing the flipping movement of the test tube rack (1). The second sliding block (21) cooperates with the first sliding block (17), making the entire flipping action more smooth and stable.

[0013] The purpose is achieved by driving the eccentric wheel (10) to rotate by the dual-axis motor in the placement chamber (11) so that the stand (8) slides back and forth in cooperation with the guide assembly, and by starting the rotary motor (19) to drive the second connecting rod (20) to rotate, and driving the test tube rack (1) to flip through the swing frame (9) and the first connecting rod (16), thereby mixing the liquid in the test tube.

[0014] It should be noted that, unless otherwise expressly specified or limited, the terms "placed in," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections such as hemming, rivet connection, pin connection, adhesive connection, and welding connection; detachable connections such as threaded connection, snap connection, and hinge connection; or integral connection; electrical connection; direct connection; indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0015] It should be further pointed out that, when describing the above specific embodiment, for the sake of simplicity and clarity, only the differences between the above specific embodiment and other embodiments are described. However, those skilled in the art should know that the above specific embodiment itself is also an independent technical solution.
