The technical realization elements of the clamping mechanism for holding the blood sample test tube

Technical realization elements:

3. This utility model aims to solve at least one of the technical problems existing in the prior art. For this reason, the present utility model proposes a clamping mechanism for clamping blood sample test tubes, which can prevent the upper cover with a large size from being squeezed deformed or broken.

4. A clamping mechanism for clamping a blood sample test tube according to some embodiments of the present invention, comprising: a mounting body, the mounting body is provided with a first mounting groove, and the first mounting groove has a first side wall A first clamping assembly, the first clamping assembly includes a first clamping member, a first elastic member, a first driving member and a first elastic pad, the first clamping member has a first clamping member arranged in the first The first mounting end in the mounting groove, the first mounting end includes a first side surface spaced apart from and opposite to the first side wall, and a second side surface disposed opposite to the first side surface. An elastic member is pressed between the first side surface and the first side wall, the first elastic pad is disposed on the second side surface, the first driving member has a first telescopic shaft, and the The first telescopic shaft is fixedly connected to the first elastic pad, and the first telescopic shaft is used to drive the first clamping member closer to or away from the first side wall; and a second clamping assembly, the first The two clamping components include a second clamping member, the second clamping member and the first clamping member are spaced apart and arranged opposite to each other, and the arrangement direction of the second clamping member and the first clamping member It is consistent with or parallel to the arrangement direction of the first side wall and the first side surface.

5. The clamping mechanism for clamping blood sample test tubes according to the embodiment of the present invention has at least the following technical effects:

6. In the above-mentioned clamping mechanism for clamping the blood sample tube, when the blood sample tube needs to be clamped, the clamping mechanism can be moved first so that the blood sample tube is located between the first clamping member and the second clamping member, and then Use the first driving member to drive the first clamping member to move toward the first side wall (because the arrangement direction of the second clamping member and the first clamping member is the same or parallel to the arrangement direction of the first side wall and the first side , The first clamping member moves toward the first side wall, that is, the first clamping member moves toward the second clamping member), so that the blood sample tube is clamped between the first clamping member and the second clamping member. In addition, since the first elastic member is pressed between the first side surface and the first side wall, and the first telescopic shaft of the first driving member is fixedly connected to the first elastic pad, even when the clamping mechanism clamps The size of the upper cover of the blood sample test tube is too large, and when the first driving member makes the first telescopic shaft extend the same distance according to the preset program, the upper cover can apply a thrust to the first clamping member, so that the first A clamping piece squeezed

The first elastic pad is pressed and moved in a direction away from the second clamping member for fine adjustment, thereby preventing the upper cover of the blood sample tube from being squeezed deformed or crushed, and the safety is high.

7. According to some embodiments of the present invention, the second side surface is provided with a first assembly groove, and the first elastic pad is arranged in the first assembly groove.

8. According to some embodiments of the present invention, the first mounting groove further has a second side wall disposed opposite to the second side surface, and the mounting body is further provided with a first mounting groove communicating with the first mounting groove. A shaft hole, the first shaft hole penetrates the second side wall; the first telescopic shaft movably penetrates the first shaft hole, and is fixedly connected with the first elastic pad.

9. According to some embodiments of the present invention, the first elastic member is a compression spring, and two ends of the first elastic member are respectively fixedly connected to the first side surface and the first side wall.

10. According to some embodiments of the present invention, the mounting body is further provided with a second mounting groove, and the notch of the second mounting groove and the notch of the first mounting groove are formed on the same part of the mounting body On the surface, the second mounting groove has a third side wall, and the third side wall is disposed opposite to the first side wall;

11. The second clamping assembly further includes a second driving member, a second elastic member, and a second elastic pad. The second clamping member has a second mounting end arranged in the second mounting groove, so The second mounting end has a third side that is spaced apart from and opposite to the third side wall, and a fourth side that is opposite to the third side, and the second elastic member is against the third side Between the wall and the third side surface, the second elastic pad is fixedly arranged on the fourth side surface, the second driving member has a second telescopic shaft, and the second telescopic shaft is connected to the second elastic The pad is fixedly connected, and the second telescopic shaft is used to drive the second clamping member to approach or move away from the third side wall.

12. According to some embodiments of the present invention, the fourth side surface is provided with a second assembly groove, and the second elastic pad is arranged in the second assembly groove.

13. According to some embodiments of the present invention, the second installation groove further has a fourth side wall disposed opposite to the fourth side surface, and the installation body is further provided with a first installation groove communicating with the second installation groove. Two shaft holes, the second shaft hole penetrates the fourth side wall, and the second telescopic shaft movably penetrates the second shaft hole and is fixedly connected with the second elastic pad.

14. According to some embodiments of the present invention, the second elastic member is a compression spring, and two ends of the second elastic member are respectively fixedly connected to the third side surface and the third side wall.

15. According to some embodiments of the present invention, a first arc-shaped concave surface is formed on the side of the first clamping member close to the second clamping member, and the second clamping member is close to the first clamping member. A second arc-shaped concave surface is formed on one side of the holding member.
