[0026] Reference Figure 1-5 This application proposes an embodiment of a test tube mixing mechanism, which includes a driving mechanism, a turntable 10, an outer ring 20, and a locking mechanism 30. The outer ring 20 is vertically mounted on the driving mechanism. The turntable 10 is coaxially and rotatably mounted inside the outer ring 20 and connected to the outer ring 20 through the locking mechanism 30. The turntable 10 has a plurality of evenly spaced test tube slots 11 on its outer periphery. The outer ring 20 has an opening 21 at its upper end. The locking mechanism 30 is configured to lock the turntable 10 and the outer ring 20 so that the openings of the test tube slots 11 are staggered with the openings 21. The driving mechanism drives the outer ring 20 and drives the turntable 10 to rotate synchronously, or unlocks the turntable 10 and the outer ring 20. The turntable 10 can rotate relative to the outer ring 20 under the action of external force so that the openings of the test tube slots 11 are aligned with the openings 21 one by one.

[0027] When using the test tube mixing mechanism with the above structure, the outer ring 20 is self-locked under the action of the driving mechanism, and the locking mechanism 30 is unlocked from the turntable 10 and the outer ring 20 in advance. At this time, the turntable 10 rotates relative to the outer ring 20 under the action of external force, so that the test tube grooves 11 are aligned with the openings 21 one by one.

[0028] When the test tube slot 11 is aligned with the opening 21, the test tube slot 11 is placed into the test tube slot 11 through the opening 21. Then, the turntable 10 is rotated to make the slot opening of the test tube slot 11 intersect with the opening 21, thus completing the loading of the test tube and the sealing of the test tube slot 11. There is no need to seal each test tube slot 11 separately, making the operation convenient.

[0029] After loading all the test tubes, continue to rotate the turntable 10 so that the openings of all the test tube slots 11 are misaligned with the openings 21. Then, lock the turntable 10 and the outer ring 20 through the locking mechanism 30 so that the driving mechanism drives the outer ring 20 to drive the turntable 10 to rotate synchronously and mix the samples in the test tubes.

[0030] After mixing is complete, the outer ring 20 returns to the position where its opening 21 faces upward, the locking mechanism 30 is unlocked, and the turntable 10 rotates relative to the outer ring 20 under the action of external force, so that the test tube slots 11 are aligned with the openings 21 one by one to remove the test tubes.

[0031] Based on the above, those skilled in the art will know that a bearing or roller is provided between the outer ring 20 and the turntable 10 so that the turntable 10 can rotate smoothly relative to the outer ring 20.

[0032] The driving mechanism includes a drive motor with a self-locking drive shaft, which is installed within the mixing mechanism. The selection and working principle of the driving mechanism are common knowledge to those skilled in the art, and this application does not provide a detailed description of the specific structure and working principle of the driving mechanism.

[0033] Preferably, the elastic component 40 on the bottom wall of the test tube trough 11 is used to make the test tubes placed in the test tube trough 11 abut against the inner wall of the outer ring 20.

[0034] See attached document Figure 1 As shown, when a test tube slot 11 is aligned with the opening 21, the test tube is placed in the test tube slot 11. Under the action of the elastic component 40, the test tube extends into the opening 21. When the test tube slot 11 and the opening 21 are intersected, the test tube in the test tube slot 11 will abut against the inner wall of the outer ring 20 under the action of the elastic component 40, so that the test tube is stably accommodated in the test tube slot 11, avoiding collision and damage to the inner wall of the test tube slot 11 during the rotation of the turntable 10. After the mixing is completed, when the turntable 10 rotates until the test tube slot 11 is aligned with the opening 21 again, the test tube extends into the opening 21 under the action of the elastic component 40, making it convenient to take out the mixed test tube.

[0035] Specifically, the elastic component 40 includes an elastic element 41 and a base 42. The base 42 is slidably disposed in the test tube groove 11 and connected to the bottom wall of the test tube groove 11 through the elastic element 41. The test tube is placed on the base 42.

[0036] Based on this, those skilled in the art can also provide a buffer pad on the inner wall of the test tube trough 11 to eliminate the gap between the trough wall of the test tube trough 11 and the test tube; a buffer pad can also be provided on the base 42 to prevent the test tube from colliding with the base 42.

[0037] When a test tube slot 11 is aligned with the opening 21, the test tube is placed into the slot 11. Under the action of the elastic component 40, the test tube extends into the opening 21. At this point, the test tube needs to be pressed to move it out of the opening 21 before the turntable 10 can continue to rotate. The inner wall of the outer ring 20 is provided with inclined surfaces 22 near both sides of the opening 21, and the side of the inclined surface 22 near the opening 21 is inclined upwards. The test tube can be moved out of the opening 21 under the action of the inclined surface 22 without manual pressing, which is convenient for operation.

[0038] Preferably, the two ends of the outer ring 20 are provided with clearance notches at the opening 21, so that people can easily take out or place test tubes by hand at the clearance notches.

[0039] Furthermore, it also includes a positioning mechanism 50, which is connected to the outer ring 20 and the turntable 10. When the turntable 10 rotates under the action of an external force, it positions the turntable 10 sequentially at the position where the groove of the test tube trough 11 is aligned with the opening 21.

[0040] When placing or removing test tubes into or from the test tube trough 11, the test tube trough 11 can be aligned with the opening 21 if necessary. The positioning mechanism 50 can position the turntable 10 sequentially at the position where the opening of the test tube trough 11 is aligned with the opening 21 for convenient use.

[0041] Based on the above, the positioning mechanism 50 includes a ball-head plunger 51, which is installed on the side of the outer ring 20 near the turntable 10. The turntable 10 is provided with a plurality of positioning holes 52, which correspond one-to-one with a plurality of test tube slots 11.

[0042] See attached document Figure 4 As shown, when the turntable 10 rotates, if any one of the positioning holes 52 is aligned with the ball plunger 51, the ball plunger 51 will extend into the positioning hole 52 to position the turntable 10, so that the turntable 10 is positioned so that the opening of the test tube groove 11 is aligned with the opening 21. If the turntable 10 continues to rotate, the positioning ball of the ball plunger 51 will overcome the elasticity of the compression spring inside and move out of the positioning hole 52, thereby releasing the positioning of the turntable 10 and the outer ring 20. The turntable 10 continues to rotate so that the ball plunger 51 is aligned with the next positioning hole 52. Under the action of the restoring force of its compression spring, the positioning ball re-extends into the next positioning hole 52, so that the opening 21 is aligned with the next test tube groove 11.

[0043] Preferably, the turntable 10 also includes a locking hole 53. When the ball-head plunger 51 is inserted into the locking hole 53, the openings of the plurality of test tube slots 11 are staggered with the opening 21. After the test tubes on the turntable 10 are loaded, the ball-head plunger 51 is inserted into the positioning hole 52, which facilitates locking the turntable 10 and the outer ring 20 using the locking mechanism 30.

[0044] Specifically, the locking mechanism 30 includes a locking member 31, the outer ring 20 has a threaded hole 24, the turntable 10 has a pin hole 12, and the locking member 31 is screwed into the threaded hole 24. (Refer to the attached diagram.) Figure 5 As shown, the turntable 10 can rotate relative to the outer ring 20 under the action of external force until the threaded hole 24 and the pin hole 12 are aligned, so that the locking member 31 can be screwed in and inserted into the pin hole 12, thereby realizing the relative locking of the turntable 10 and the outer ring 20.

[0045] Preferably, the turntable 10 has an observation window 13 on its front side that corresponds to one of the multiple test tube slots, so that staff can easily identify whether test tubes are placed in the multiple test tube slots.

[0046] Furthermore, the turntable 10 is also provided with a handle 14 on the front side, which makes it convenient for staff to hold the handle 14 to rotate the turntable.

[0047] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
