[0002] Shaking devices are widely used in the medical and chemical industries. For example, many instruments, such as fluorescence immunoassay analyzers, require blood samples to be shaken before testing to obtain data and interpret results. Therefore, the shaking effect of the shaking device directly affects the performance of the entire testing instrument.

[0003] In the prior art, for example, patent application CN205246424U discloses a blood sample mixing device for test tubes. This device uses a crankshaft structure, a pressure plate, and a sealing plate to drive a motor to perform eccentric motion on the test tube placement stage, thereby mixing the blood sample in the test tube. However, the shaking amplitude of this device is small, resulting in poor mixing effect and slow mixing speed, which affects the test results and the instrument's detection efficiency.

[0036] A method of using a shaking device, applied to a shaking device, includes the following steps:

[0037] During the process of the tensioning clamp tightening the tube body: First, the locking mechanism controls the inner rotating shaft to remain locked relative to the outer rotating shaft; then, the power source drives the outer rotating shaft to rotate in the first direction, and the outer rotating shaft abuts against the clutch plate and the inner rotating shaft, causing both of them to move in the direction of the tensioning clamp, thereby tightening the tube body;

[0038] During the process of the tensioning clamp releasing the tube body: First, the locking mechanism controls the inner rotating shaft to remain locked relative to the outer rotating shaft; then, the power source drives the outer rotating shaft to rotate in the second direction, the clutch plate moves away from the abutment surface of the inner rotating shaft, and the inner rotating shaft moves away from the tensioning clamp direction, thereby releasing the tube body; wherein, the second direction on the outer rotating shaft is opposite to the rotation direction of the first direction;

[0039] During the process of the tensioning clamp tightening the tube body and driving the tube body to rotate and oscillate: the locking mechanism releases the relative locking of the inner rotating shaft and the outer rotating shaft, and the tensioning clamp maintains the tightening state of the tube body; the power source sequentially drives the tube body to rotate 360 ​​degrees in the vertical plane through the outer rotating shaft, the clutch plate, and the inner rotating shaft that cooperates with the tensioning clamp; the clutch plate is tightly connected to the contact surface of the inner rotating shaft through the clamping force, and the friction force makes the two rotate synchronously.

[0040] Optionally, during the process of the tensioning clamp tightening the tube body: the power source drives the outer rotating shaft to rotate in the first direction, and the outer rotating shaft abuts against the protruding part of the concave and convex surfaces on the clutch plate through the driving part, so as to drive the clutch plate to abut against the inner rotating shaft, pushing the inner rotating shaft and the tensioning clamp to tighten the tube body; and / or,

[0041] During the process of the tensioning clamp releasing the tube body: the power source drives the outer rotating shaft to rotate in the second direction; the outer rotating shaft abuts against the concave position of the concave-convex surface on the clutch plate via the driving part; the first elastic element between the outer rotating shaft and the clutch plate is compressed during the tightening of the tube body and released during the loosening of the tube body, pushing the clutch plate away from the abutting surface of the inner rotating shaft, and the clutch plate is in contact with the outer rotating shaft; and / or,

[0042] During the process of the tensioning clamp tightening the tube body and driving the tube body to rotate and oscillate: the outer rotating shaft abuts against the protruding position of the concave and convex surfaces on the clutch plate through the driving part, and the clutch plate is driven to abut tightly against the contact surface of the inner rotating shaft, so as to push the inner rotating shaft and the tensioning clamp to cooperate to tighten the tube body.

[0043] The technical solution of this invention has the following advantages:

[0044] 1. The shaking device provided by the present invention includes:

[0045] Tensioning clamp is used to hold a tube that needs to be shaken evenly. The tensioning clamp has a tightened state that tightens the tube and a loosened state that releases the tube.

[0046] The driving mechanism includes: a power source; the power source is indirectly connected to the inner rotating shaft to drive the inner rotating shaft to rotate around its circumference; the inner rotating shaft cooperates with the tensioning clamp to clamp the tube body and drive the tube body to rotate 360 ​​degrees in the vertical plane and shake the tube body evenly.

[0047] A clutch ring includes an outer rotating shaft and a clutch plate; the outer rotating shaft is sleeved on the inner rotating shaft, and the outer rotating shaft is driven by the power source and drives the inner rotating shaft to switch between the tightened state and the loosened state through the clutch plate;

[0048] A locking mechanism is connected to the inner rotating shaft via a transmission; in the released state, the locking mechanism controls the inner rotating shaft to remain locked relative to the outer rotating shaft to achieve a tightening action; in the tightened state, the inner rotating shaft moves synchronously relative to the outer rotating shaft to achieve a shaking action.

[0049] In this invention, a locking mechanism achieves relative locking of the inner and outer rotating shafts. During the tightening of the tube by the tensioning clamp, the power source drives the outer rotating shaft to rotate, which in turn moves the clutch plate towards the contact surface of the inner rotating shaft. This allows the inner rotating shaft to engage with the tensioning clamp and tighten the tube. Furthermore, the locking mechanism also achieves relative locking of the inner and outer rotating shafts. During the loosening of the tube by the tensioning clamp, the power source drives the outer rotating shaft to rotate in the opposite direction, which in turn moves the clutch plate away from the contact surface of the inner rotating shaft. This allows the inner rotating shaft to separate from the tensioning clamp and loosen the tube. Additionally, when the locking mechanism is released, a clamping force can be used to ensure close contact between the clutch plate and the contact surface of the inner rotating shaft. Friction forces cause the outer rotating shaft to drive the inner rotating shaft to rotate. The inner rotating shaft, in conjunction with the tensioning clamp, causes the tube to rotate 360 ​​degrees in the vertical plane, achieving even rotation of the tube. The above structure is simple and reliable, and it can also enable the tube to rotate 360 ​​degrees quickly in the vertical plane, thereby improving the shaking effect and shaking speed.

[0050] 2. The shaking device provided by the present invention has a driving surface at one end of the outer rotating shaft facing the clutch plate for driving the clutch plate to abut against the inner rotating shaft to achieve the clamping state;

[0051] One of the driving surface and the clutch plate is provided with a concave-convex surface, and the other of the two is provided with a driving part adapted to the concave-convex surface; during the relative rotation of the driving surface and the clutch plate, the driving part abuts against the convex surface of the concave-convex surface, so as to drive the inner rotating shaft to move toward the tensioning clamp direction through the clutch plate to achieve the clamping state.

[0052] In this invention, the cooperating concave and convex surfaces and the driving part can effectively realize the outer rotating shaft pushing the clutch plate to move in the axial direction of the inner rotating shaft during rotation. The above structure is simple and reliable, and can stably realize the tightening and loosening of the tube body.

[0053] 3. The shaking device provided by the present invention has a sliding step on the inner rotating shaft. The sliding step guides the clutch plate to slide in the length direction of the inner rotating shaft and restricts the clutch plate from rotating in the circumferential direction of the inner rotating shaft.

[0054] In this invention, by setting a sliding step on the inner rotating shaft, the clutch plate can be effectively guided to slide in the length direction of the inner rotating shaft and the clutch plate can be restricted to rotate in the circumferential direction of the inner rotating shaft. This ensures that the rotation of the outer rotating shaft will only drive the clutch plate to slide in the length direction of the inner rotating shaft and will not cause rotation.

[0055] 4. In the shaking device provided by the present invention, a first elastic element is further provided between the outer rotating shaft and the clutch plate to drive the two to separate. The first elastic element is used to drive the clutch plate away from the outer rotating shaft and make the clutch plate fit against the outer rotating shaft to achieve the released state.

[0056] In this invention, by using the first elastic element provided between the outer rotating shaft and the clutch plate, it can be effectively ensured that the clutch plate and the driving surface of the outer rotating shaft remain in contact during the rotation of the outer rotating shaft, and the clutch plate is driven away from the outer rotating shaft to realize the release action of the tube body.

[0057] 5. The shaking device provided by the present invention further includes: a vertical sensing switch for detecting the rotational position of the tube; the inner rotation shaft limiting linkage has an extension end corresponding to the vertical sensing switch; when the extension end enters the sensing position of the vertical sensing switch, it is determined whether the tube is in a vertical state.

[0058] In this invention, the rotational position of the tube can be effectively detected by the aforementioned vertical sensing switch, thereby keeping the tube in a vertical state during the tightening and loosening process.

[0059] 6. The shaking device provided by the present invention further includes:

[0060] An external rotating shaft linkage component is fixedly mounted on the external rotating shaft and rotates synchronously with the external rotating shaft;

[0061] A clamping induction switch is used to detect the rotational position of the outer rotating shaft; the outer rotating shaft linkage has an extension end corresponding to the clamping induction switch; when the extension end enters the sensing position of the clamping induction switch, it is determined that the tensioning clamp is in the tightened state or the loosened state.

[0062] In this invention, the rotation position of the outer rotating shaft can be effectively detected by the outer rotating shaft linkage component set on the outer rotating shaft, thereby determining whether the tensioning clamp is in a tightened or loosened state.

[0063] 7. The shaking device provided by the present invention, wherein the tensioning clamp comprises: a positioning cover, and a pressing top and a second elastic member disposed within the positioning cover;

[0064] The positioning cover is provided with a limiting step, and the second elastic element is connected to the limiting step and the pressing top respectively; when the clamping state is reached, the clutch plate is driven to push the inner rotating shaft toward the positioning cover, the pressing top abuts against the inner rotating shaft, and the second elastic element compresses and pushes the positioning cover to abut tightly against the tube body.

[0065] In this invention, by providing a clamping top and a second elastic element within the positioning cover, and by providing a limiting step corresponding to the second elastic element within the positioning cover, the following can be effectively achieved: In the clamping state, when the clutch plate is driven to push the inner rotating shaft toward the positioning cover, the clamping top abuts against the inner rotating shaft, thereby compressing the second elastic element and pushing the positioning cover to tightly abut against the tube body.

[0081] See Figure 1 and Figure 8 , Figure 1 An explosion diagram of the shaking device in an embodiment of the present invention is shown; Figure 8 A three-dimensional structural schematic diagram of the shaking device in an embodiment of the present invention is shown.

[0082] The shaking device provided in this embodiment includes:

[0083] Tensioning clamp 1 is used to clamp the tube body 2 that needs to be shaken evenly. The tensioning clamp 1 has a tightened state for tightening the tube body 2 and a loosened state for loosening the tube body 2. The tensioning clamp 1 is also provided with an elastic pad for protecting the tube body 2. The tensioning clamp 1 is also provided with a height limiting bracket 30 for supporting the tube body 2 and for limiting the installation height of the tube body 2 on the tensioning clamp 1.

[0084] The driving mechanism includes: a power source 3; the power source 3 is indirectly connected to the inner rotating shaft 4 to drive the inner rotating shaft 4 to rotate around its circumference; the inner rotating shaft 4 cooperates with the tensioning clamp 1 to clamp the tube body 2, and drives the tube body 2 to rotate 360 ​​degrees in the vertical plane and shake the tube body 2 evenly.

[0085] Clutch ring 5, such as Figure 2 The diagram shown is an enlarged view of the connection structure between the outer rotating shaft, clutch plate, and inner rotating shaft in the clamped state. The clutch ring 5 includes an outer rotating shaft 6 and a clutch plate 7. The outer rotating shaft 6 is sleeved on the inner rotating shaft 4. Driven by the power source 3, the outer rotating shaft 6 drives the inner rotating shaft 4 and the tensioning clamp 1 to switch between the clamping state and the loosening state via the clutch plate 7. In this embodiment, the outer rotating shaft 6 is rotatably connected to the inner rotating shaft 4 via an inner bearing to achieve the clamping and loosening of the tube body 2.

[0086] Locking mechanism 13 is connected to the inner rotating shaft 4 via a transmission; for example Figure 6 and Figure 7 As shown, in the released state, the locking mechanism 13 controls the inner rotating shaft 4 to remain locked relative to the outer rotating shaft 6 to achieve a tightening action; in the tightened state, the inner rotating shaft 4 moves synchronously relative to the outer rotating shaft 6 to achieve a shaking action.

[0087] In this embodiment, refer to Figure 4 The schematic diagram of the three-dimensional structure of the external rotation axis shown; and, Figure 5 The diagram shows a three-dimensional structure of the clutch plate. The outer rotating shaft 6 has a driving surface 8 at one end facing the clutch plate 7, used to drive the clutch plate 7 to abut against the inner rotating shaft 4 to achieve the clamping state. The clutch plate 7 has a concave-convex surface 9, and the driving surface 8 has a driving part 10 adapted to the concave-convex surface 9. Furthermore, the concave-convex surface 9 is a smoothly transitioning inclined surface on the clutch plate 7, and the driving part 10 is a cam mounted on the outer rotating shaft 6; a positioning groove 12 is also provided on the inclined surface to limit the cam in the clamping state. During the relative rotation of the driving surface 8 and the clutch plate 7, the driving part 10 abuts against the convex surface of the concave-convex surface 9, thereby driving the inner rotating shaft 4 to move towards the tensioning clamp 1 through the clutch plate 7 to achieve the clamping state.

[0088] In addition, such as Figure 1As shown, a first elastic element 11 is provided between the outer rotating shaft 6 and the clutch plate 7 to drive them to separate.

The sliding step 20 effectively guides the clutch plate 7 to slide along the length of the inner rotating shaft 4 and restricts its rotation in the circumferential direction, thus ensuring that the rotation of the outer rotating shaft 6 only drives the clutch plate 7 to slide along the length of the inner rotating shaft 4, without causing rotational movement.

[0090] In this embodiment, as Figure 6 The diagram shows a three-dimensional structure of the shaking device in the released state, ready to tighten the tank. The locking mechanism 13 includes:

[0092] The telescopic limiting member 15 is an electromagnet-controlled telescopic column. The telescopic limiting member 15 extends under drive and abuts against the first extension end 16 of the inner rotating shaft limiting linkage member 14 to prevent the inner rotating shaft 4 from rotating; the telescopic limiting member 15 retracts under drive to release the rotation limitation on the inner rotating shaft 4.

[0093] Furthermore, in this embodiment, as Figure 7 The image shows a longitudinal cross-sectional view of the shaking device in the released state. The tensioning clamp 1 includes: a positioning cover 25, and a clamping top 26 and a second elastic element 27 disposed within the positioning cover 25; the clamping top 26 is a nut structure, and the second elastic element 27 is a spring sleeved on the clamping top 26; the clamping top 26 is symmetrically disposed on the positioning cover 25, located on both sides of the tube body 2.

[0094] The positioning cover 25 is provided with a limiting step 28. The second elastic member 27 is connected to the limiting step 28 and the pressing top member 26 respectively. When the clamping state is reached, the clutch plate 7 is driven to push the inner rotating shaft 4 toward the positioning cover 25. The pressing top member 26 abuts against the inner rotating shaft 4, and the second elastic member 27 compresses and pushes the positioning cover 25 to abut tightly against the tube body 2.

[0095] In this embodiment, as Figure 6 The diagram shows a three-dimensional structural schematic of the shaking device in the loosened state, ready to tighten the tank. The shaking device also includes: a vertical induction switch 17 for detecting the rotational position of the tube 2; the inner rotation shaft limiting linkage 14 has an extension end corresponding to the vertical induction switch 17; when the extension end enters the sensing position of the vertical induction switch 17, it is determined whether the tube 2 is in a vertical state.

[0096] In this embodiment, as Figure 6 The diagram shows a three-dimensional structure of the shaking device in its loosened state, ready to tighten the tank. The shaking device also includes:

[0097] The outer rotation shaft linkage 18 is fixedly mounted on the outer rotation shaft 6 and rotates synchronously with the outer rotation shaft 6.

The driving mechanism further includes: a pulley 22 and a belt 23 fixedly mounted on the outer rotating shaft 6, and a frame 24; the power source 3 and the pulley 22 are mounted on the frame 24, and the outer rotating shaft 6 is rotatably connected to the frame 24 via an outer bearing 31. The power source 3 drives the outer rotating shaft 6 to rotate sequentially through the belt 23 and the pulley 22. The power source 3 is a stepper motor, which drives the pulley 22 to rotate via a drive shaft 32 connected to one end of the belt 23.

[0100] Additionally, in this embodiment, as Figure 6 The diagram shows a three-dimensional structural representation of the shaking device in the loosened state, ready to tighten the tank. The shaking device also includes a tube detection switch 29 for detecting whether the tube 2 is mounted on the tensioning clamp 1; this tube detection switch 29 is a reactive photoelectric switch.

[0101] A method of using a shaking device includes the following steps:

[0102] During the process of the tensioning clamp 1 tightening the tube body 2: First, the locking mechanism 13 controls the inner rotating shaft 4 to remain locked relative to the outer rotating shaft 6; then, the power source 3 drives the outer rotating shaft 6 to rotate in the first direction, and the outer rotating shaft 6 abuts against the protruding position of the concave and convex surface 9 on the clutch plate 7 through the driving part 10, so as to drive the clutch plate 7 to abut against the inner rotating shaft 4, and push the inner rotating shaft 4 and the tensioning clamp 1 to tighten the tube body 2;

[0103] During the process of the tensioning clamp 1 releasing the tube body 2: First, the locking mechanism 13 controls the inner rotating shaft 4 to remain locked relative to the outer rotating shaft 6; then, the power source 3 drives the outer rotating shaft 6 to rotate in a second direction, and the second direction on the outer rotating shaft 6 is opposite to the rotation direction of the first direction. The power source 3 drives the outer rotating shaft 6 to rotate in the second direction, and the outer rotating shaft 6 abuts against the concave position of the concave and convex surfaces 9 on the clutch plate 7 through the driving part 10. The first elastic element 11 between the outer rotating shaft 6 and the clutch plate 7 is compressed during the process of tightening the tube body 2, and releases the elastic force of the first elastic element 11 during the process of releasing the tube body 2, pushing the clutch plate 7 away from the abutting surface 21 of the inner rotating shaft 4. The clutch plate 7 is in contact with the outer rotating shaft 6, thereby realizing the release of the tube body 2.

[0104] During the process of the tensioning clamp 1 tightening the tube body 2 and driving the tube body 2 to rotate and oscillate: the locking mechanism 13 releases the relative locking of the inner rotating shaft 4 and the outer rotating shaft 6, and the tensioning clamp 1 maintains the tightening state of the tube body 2. The outer rotating shaft 6 abuts against the protruding position of the concave and convex surface 9 on the clutch plate 7 through the driving part 10, and the clutch plate 7 is driven to tightly abut against the abutting surface 21 of the inner rotating shaft 4, so as to push the inner rotating shaft 4 and the tensioning clamp 1 to cooperate in tightening the tube body 2. In the above process, the power source 3 drives the tube body 2 to rotate 360 ​​degrees in the vertical plane through the outer rotating shaft 6, the clutch plate 7 and the inner rotating shaft 4 which is tightened in cooperation with the tensioning clamp 1 in sequence; the clutch plate 7 is tightly connected to the abutting surface 21 of the inner rotating shaft 4 through the clamping force, and the friction force makes the two rotate synchronously.

[0105] Of course, the specific positions of the concave-convex surface 9 and the driving part 10 are not limited in this embodiment. In other embodiments, the outer rotating shaft 6 has a driving surface 8 at one end facing the clutch plate 7 for driving the clutch plate 7 to abut against the inner rotating shaft 4 to achieve the clamping state. The clutch plate 7 is provided with a driving part 10, and the driving surface 8 is provided with a concave-convex surface 9 that matches the concave-convex surface 9. During the relative rotation of the driving surface 8 and the clutch plate 7, the driving part 10 abuts against the convex surface of the concave-convex surface 9, so as to drive the inner rotating shaft 4 to move toward the tensioning clamp 1 through the clutch plate 7 to achieve the clamping state.

[0106] Of course, in this embodiment, the first elastic element 11 disposed between the outer rotating shaft 6 and the clutch plate 7 is not specifically limited. In other embodiments, the first elastic element 11 may also be a rubber element disposed between the outer rotating shaft 6 and the clutch plate 7. The clutch plate 7 is driven away from the outer rotating shaft 6 by the rubber element, so that the clutch plate 7 is in contact with the outer rotating shaft 6, thereby realizing the released state.

[0107] Of course, the specific structure of the second elastic member 27 is not specifically limited in this embodiment. In other embodiments, the tensioning clamp 1 includes: a positioning cover 25, and a pressing top 26 and a second elastic member 27 disposed in the positioning cover 25; the pressing top 26 is a nut structure, and the second elastic member 27 is a rubber part sleeved on the pressing top 26; the pressing top 26 is symmetrically disposed on the positioning cover 25 and located on both sides of the tube body 2.

[0108] Of course, the connection method between the outer rotating shaft 6 and the inner rotating shaft 4 is not specifically limited in this embodiment. In other embodiments, the outer rotating shaft 6 is directly sleeved on the inner rotating shaft 4, and the outer rotating shaft 6 and the inner rotating shaft 4 are rotatably connected to achieve the action of tightening and loosening the tube body 2.

[0109] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
