[0048] The rotating assembly 2 includes a second driving member 21 provided on the seat body 14 and a rotating shaft 22 connected to the second driving member 21, and the rotating shaft 22 is perpendicular to the swinging shaft 13;

[0049] Here, it can be understood that the rotating assembly 2 refers to the assembly for rotating the sample tube 4 so that the sample in the sample tube 4 can be shaken evenly; the rotating assembly 2 includes a second driving member 21 and a rotating shaft 22; the second driving member 21 refers to the driving member for driving the sample tube 4 to rotate, and the second driving member 21 generally refers to a motor capable of outputting power; the rotating shaft 22 refers to the shaft body for driving the rotation of the sample tube rack 31, and at the same time the rotating shaft 22 serves as the shaft body for the sample tube rack 31 to rotate.

The sample tube rack 31 is provided with a sample tube groove 32 for accommodating the sample tube 4, and the sample tube groove 32 is provided with an elastic member 33 for clamping the sample tube 4;

[0051] Here, it can be understood that the sample tube assembly 3 refers to the assembly for fixing the sample tube 4; the sample tube assembly 3 includes a sample tube holder 31, on which there is a sample tube groove 32, and the shape and size of the sample tube groove 32 match those of the sample tube 4, so that the sample tube groove 32 can be used to accommodate the sample tube 4; the sample tube groove 32 is provided with an elastic member 33, and the elastic member 33 can deform under force. Therefore, when the sample tube 4 is inserted into the sample tube groove 32, the sample tube 4 presses the elastic member 33, and the elastic member 33 deforms to exert a force on the sample tube 4, thereby realizing the clamping of the sample tube 4; the elastic member 33 generally refers to the folds formed in the sample tube groove 32, and the folds are formed by the inner lining sleeve 321.

[0052] Among them, the first driving member 12 is used to drive the seat body 14 to swing around the swing axis 13; the second driving member 21 is used to drive the sample tube holder 31 to rotate around the rotation axis 22.

[0053] The working principle of the sample tube shaking device provided in this embodiment is as follows:

[0054] Insert the sample tube 4 into the sample tube groove 32, and the elastic member 33 is squeezed to exert a reaction force on the sample tube 4, so that the sample tube 4 is clamped in the sample tube groove 32; start the first driving member 12 and the second driving member 21.

[0055] By adopting the above technical solution, first, there is a sample tube groove 32 on the sample tube holder 31, and an elastic member 33 for clamping the sample tube 4 is provided in the sample tube groove 32. In this way, the firmness of the sample tube 4 in the sample tube groove 32 is improved, and the risk of the sample tube 4 falling off is reduced; in addition, the sample tube holder 31 rotates around the swing axis 13 and the rotation axis 22 at the same time, which improves the shaking degree of the sample tube 4. At the same time, it also reduces the space occupied by the sample tube holder 31 during shaking, reduces the possibility of interference with other components, and reduces the risk of damage to the sample tube holder 31 and other components.

[0056] In one embodiment, a preset angle is formed between the swing axis 13 and the rotation axis 22. Preferably, the swing axis 13 is perpendicular to the rotation axis 22, so that the sample tube 4 can rotate around two shaft bodies in different directions, improving the shaking degree and efficiency of the sample tube 4.

[0057] In one embodiment, the first driving member 12 is provided with a first driving shaft 121, and the first driving shaft 121 is provided with a first gear 122. The first gear 122 is coaxially arranged with the first driving shaft 121. The swing axis 13 is perpendicular to the first driving shaft 121, and a second gear 131 meshing with the first gear 122 is provided on the swing axis 13. The second gear 131 is coaxially arranged with the swing axis 13 and perpendicular to the first gear 122.

[0058] Here, it can be understood that the first driving member 12 generally refers to a motor. The first driving member 12 is provided with a first driving shaft 121. That is, the power of the first driving member 12 is output through the first driving shaft 121. The first driving member 12 drives the first driving shaft 121 to rotate around the axis. A first gear 122 is coaxially arranged on the first driving shaft 121, and then drives the first gear 122 to rotate around the first driving shaft 121; the swing shaft 13 is perpendicular to the first driving shaft 121, that is, the axis of the swing shaft 13 is perpendicular to the axis of the first driving shaft 121; a second gear 131 is arranged on the swing shaft 13. The second gear 131 meshes with the first gear 122. The second gear 131 is coaxially arranged with the swing shaft 13, and the axis of the second gear 131 is perpendicular to the axis of the first gear 122.

[0059] By adopting the above technical solution, the transmission direction of the power output by the first driving member 12 is adjusted, so that the first driving shaft 121 and the swing shaft 13 can be vertically arranged, which is beneficial to the cooperation between the rotating assembly 2 and the swing assembly 1.

[0060] Please refer to Figure 2 and Figure 3 , in an embodiment, bearings 132 are arranged between the two ends of the swing shaft 13 and the housing 11. The bearing 132 includes an outer ring and an inner ring that can rotate relative to the outer ring. The end of the swing shaft 13 is connected to the inner ring, and the outer ring is arranged on the housing 11.

[0061] Here, it can be understood that the bearing 132 is a component used to support a mechanical rotating body; the bearing 132 includes an outer ring and an inner ring. The inner ring can rotate relative to the outer ring through balls or lubricants arranged along the circumference. Among them, the end of the swing shaft 13 is connected to the inner ring of the corresponding bearing 132, and the outer ring of the corresponding bearing 132 is arranged on the housing 11. In this way, the swing shaft 13 can rotate around the axis relative to the housing 11.

[0062] By adopting the above technical solution, the function of the swing shaft 13 rotating relative to the housing 11 is realized, and the smoothness of the swing shaft 13 during rotation is improved.

[0063] Please refer to Figure 2 again. In an embodiment, the seat body 14 includes a seat body main body 141 and two legs 142 oppositely arranged on the seat body main body 141. The two legs 142 are arranged at intervals. The housing 11 is located between the two legs 142. The two ends of the swing shaft 13 respectively extend out of the housing 11 and are connected to the corresponding legs 142.

[0064] Here, it can be understood that the seat body 14 includes a seat body main body 141 and legs 142. The legs 142 are connected to the swing shaft 13, and the bracket has a certain length. In this way, the seat body main body 141 can rotate around the swing shaft 13 to realize swinging.

[0065] It should be further explained that the rotating assembly 2 is provided on the seat body 141, so that both the rotating assembly 2 and the sample tube assembly 3 provided on the rotating assembly 2 can rotate around the swing axis 13 to achieve swinging.

[0066] By adopting the above technical solution, the swinging function of the seat body 14 driving the rotating assembly 2 and the sample tube assembly 3 is realized.

[0067] As Figure 4 shown, in one embodiment, the sample tube rack 31 includes a rack body 311 and a plurality of sample tube slots 32 provided on the rack body 311, and the plurality of sample tube slots 32 are uniformly arranged around the rotation axis 22.

[0068] Here, it can be understood that the sample tube rack 31 includes a rack body 311 and a plurality of sample tube slots 32, and each sample tube slot 32 is used to accommodate at least one sample tube 32. In this way, the number of sample tubes 4 fixed by the sample tube rack 31 is increased, and the efficiency of the shaking operation is improved; in addition, the plurality of sample tube slots 32 are uniformly arranged around the rotation axis 22, so that when the sample tube rack 31 rotates around the rotation axis 22, the center of gravity of the sample tube rack 31 still remains coincident with or close to the rotation axis 22, which reduces the possibility of eccentric rotation of the sample tube rack 31 and improves the stability of the sample tube rack 31.

[0069] By adopting the above technical solution, the efficiency and stability of the shaking operation of the sample tube rack 31 are improved.

[0070] In one embodiment, the sample tube slot 32 is provided with a lining sleeve 321, and the lining sleeve 321 is provided with a flexible elastic member 33.

[0071] Here, it can be understood that the lining sleeve 321 is a component for strengthening the sample tube 4 placed in the sample tube slot 32; the lining sleeve 321 generally refers to a silica gel sleeve. In this way, the lining sleeve 321 is provided with an elastic member 33, the elastic member 33 is a flexible member and has elasticity, and the elastic member 33 can be deformed under pressure when the sample tube 4 is placed in the sample tube slot 32, and the elastic member 33 exerts a reaction force on the sample tube 4. In this way, the stability of the sample tube 4 during fixation is improved.

[0072] It should be further explained that the inner wall of the lining sleeve 321 is formed with wrinkles, and the wrinkles are elastic members 33 with elasticity.

[0073] By adopting the above technical solution, the stability of the sample tube 4 during fixation is improved.

[0074] In one embodiment, the lining sleeve 321 includes a plurality of lining sleeve units 3211 arranged in layers in the depth direction of the sample tube slot 32 in sequence, and each lining sleeve unit 3211 is provided with a plurality of elastic members 33.

[0075] Here, it can be understood that the inner liner units 3211 are stacked in sequence along the depth direction of the sample tube groove 32. In this way, when the sample tube 4 is inserted along the groove depth direction of the sample tube groove 32, multiple inner liner units 3211 are arranged in sequence in the groove depth direction. That is, the elastic members 33 of the multiple inner liner units 3211 respectively exert reaction forces on different parts of the sample tube 4, making the stability of the sample tube 4 higher when it is fixed.

[0076] By adopting the above technical solution, the stability of the sample tube 4 in the sample tube groove 32 is further improved.

[0077] In one embodiment, the multiple elastic members 33 are uniformly arranged around the central axis of the inner liner unit 3211.

[0078] Here, it can be understood that when the sample tube 4 is inserted into the sample tube groove 32, the central axis of the sample tube 4 coincides or substantially coincides with the central axis of the inner liner unit 3211. In this way, by uniformly arranging the multiple elastic members 33 around the central axis of the inner liner unit 3211, the force on the sample tube 4 in its own circumferential direction is made uniform, further improving the stability of the sample tube 4.

[0079] By adopting the above technical solution, the stability of the sample tube 4 is further improved.

[0080] In one embodiment, the inner liner 321 further includes a spacer 3212 provided between two adjacent inner liner units 3211, and the spacer 3212 is used to support the inner liner unit 3211.

[0081] Here, it can be understood that the spacer 3212 refers to a component used to separate two adjacent inner liner units 3211; the spacer 3212 is generally a hard plastic sheet.

[0082] By adopting the above technical solution, the mechanical strength of the inner liner 321 is improved, which is beneficial to improving the durability of the inner liner 321.

[0083] In a second aspect, a blood collection system is provided, including a blood collection device and the above-mentioned sample tube shaking device, and the sample tube shaking device is used in cooperation with the blood collection device.

[0084] By adopting the above technical solution, on the basis of having the advantages of the sample tube shaking device in the above embodiments, the blood collection system of this embodiment also has the advantage of high blood collection efficiency.

[0085] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
