[0037] To enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0038] See Figures 1-4 ;

[0039] The multi-angle test tube shaking rack of this embodiment includes an oscillator 1, which can be an oscillator commonly used currently and has the function of adjusting the oscillation frequency and amplitude. A cross-frame structure is arranged on the working surface of the oscillator 1, and a bracket structure with an adjustable inclination angle is arranged on the cross-frame structure. The bracket structure is used to fixedly support the test tube rack 2 for test tubes, so as to adjust the inclination angle of the bracket structure, and then adjust the inclination angle of the test tube rack 2 for fixedly supporting the test tubes, so as to be able to shake the sample and exhaust air bubbles according to needs, and to achieve different shaking effects by adjusting the inclination angle of the sample.

[0040] An adjustment mechanism is arranged between the cross-frame structure and the bracket structure to drive the bracket structure to rotate to adjust the inclination angle.

[0041] A test tube fixing mechanism is arranged on the bracket structure to fix the test tube rack 2 on the bracket structure. Furthermore, multiple test tubes can be supported by the test tube rack 2, and then the test tubes loaded with samples can be fixedly arranged on the bracket structure in batches, so as to shake and exhaust air bubbles for a large number of samples through the oscillator 1, improving work efficiency.

[0042] Furthermore, the cross-frame structure includes:

[0043] Vertical plates 3, which are two groups symmetrically arranged on the working surface of the oscillator 1; and

[0044] A horizontal plate 4, which is horizontally arranged between the two groups of vertical plates 3, and the two groups of vertical plates 3 are used to fixedly support the horizontal plate 4.

[0045] Furthermore, the bracket structure includes a support plate 5 and side baffles 6. One end of the support plate 5 is hinged to the upper surface of the horizontal plate 4, so that the horizontal plate 4 can rotate to adjust its inclination angle. The side baffles 6 are vertically arranged at one end of the support plate 5 hinged to the horizontal plate 4. The support plate 5 is used to support the test tube rack 2, so as to adjust the inclination angle of the sample on the test tube rack 2 by adjusting the inclination angle of the support plate 5.

[0046] Furthermore, the adjustment mechanism includes:

[0047] An assembly opening 7, which is arranged at the connection part of the support plate 5 and the side baffles 6;

[0048] A first long-tooth gear 8, which is fixedly connected in the assembly opening 7;

[0049] Horizontal chutes 9, which are two groups symmetrically opened on the upper surface of the horizontal plate 4, and the horizontal chutes 9 and the first long-tooth gear 8 are vertically distributed.

[0050] The rack 10 is arranged in the horizontal chute 9 and slides therein. There are two sets of racks 10 with the same structure, which are arranged in one-to-one correspondence with the two sets of horizontal chutes 9. The rack 10 meshes with the first long-tooth gear 8.

[0051] The driving rotating shaft 11 is horizontally arranged on the upper surface of the cross plate 4 and is arranged parallel to the first long-tooth gear 8. The driving rotating shaft 11 is rotatably arranged on the cross plate 4 through a bearing, and a knob 12 is arranged at one end of the driving rotating shaft 11; and

[0052] The second long-tooth gear 13 is coaxially arranged on the driving rotating shaft 11 and meshes with the rack 10.

[0053] Specifically, by manually rotating the knob 12, the driving rotating shaft 11 drives the second long-tooth gear 13 to rotate. Then, through the meshing between the second long-tooth gear 13 and the rack 10, the rack 10 is driven to move along the horizontal chute 9. Further, through the transmission cooperation of the meshing between the rack 10 and the first long-tooth gear 8, the first long-tooth gear 8 rotates, and drives the support plate 5 to rotate, so as to adjust the rotation angle of the support plate 5 according to the rotation angle of the first long-tooth gear 8, and further adjust the inclination angle of the support plate 5.

[0054] Further, a support body 14 straddling above the driving rotating shaft 11 is arranged on the upper surface of the cross plate 4. A tightening bolt 15 is screwed into the top end of the support body 14, and the tightening bolt 15 is used to press tightly on the driving rotating shaft 11 to limit the rotation of the driving rotating shaft 11. After the driving rotating shaft 11 drives the second long-tooth gear 13 to rotate and adjusts the inclination angle of the support plate 5, it is necessary to fix the adjusted state. Therefore, in order to prevent the driving rotating shaft 11 from rotating by itself, the tightening bolt 15 is pressed tightly on the driving rotating shaft 11 to limit the rotation of the driving rotating shaft 11, and further fix the inclination angle of the support plate 5.

[0055] Further, the test tube fixing mechanism includes:

[0056] The first hook bodies 16 are arranged at one end of the bottom of the support plate 5 opposite to the side baffle 6. The first hook bodies 16 are multiple and horizontally distributed;

[0057] The second hook bodies 17 are arranged at the upper end of the side baffle 6 opposite to the side of the support plate 5. The second hook bodies 17 are multiple and horizontally distributed and are arranged in one-to-one correspondence with the multiple first hook bodies 16; and

[0058] The elastic band 18 has both ends respectively hung on the corresponding first hook bodies 16 and second hook bodies 17 through hooks, and the test tube rack 2 is tightened and fixed on the support plate 5.

[0059] Specifically, after placing the test tube rack 2 on the pallet 5, both ends of the elastic band 18 are respectively hung on the corresponding first hook body 16 and the second hook body 17 through the hooks, so that the tightened elastic band 18 is tightened on the test tube rack 2, thereby realizing the fixation of the test tube rack 2 on the pallet 5 by the elastic band 18. In order to fix the test tube rack 2 more stably, multiple elastic bands 18 are provided for fixation, and the number of the elastic bands 18 corresponds one by one to the multiple first hook bodies 16.

[0060] Furthermore, a notch 19 for the elastic band 18 to pass through is provided at the upper end of the side baffle 6. The notches 19 are multiple and horizontally distributed and are arranged in one-to-one correspondence with the multiple second hook bodies 17. When fixing the test tube rack 2 with the elastic band 18, in order to prevent the elastic band 18 from moving in a direction perpendicular to its own extension direction and affecting the fixation of the test tube rack 2, a notch 19 is provided at the upper end of the side baffle 6 to limit the position movement of the elastic band 18, thereby fixing the test tube rack 2 more stably.

[0061] In the above technical solution, the multi-angle test tube oscillator provided by the present utility model has the following beneficial effects:

[0062] The present utility model can adjust the angle of the test tube rack according to the volume of the solution and the oscillation amplitude of the oscillator, so as to achieve the use purpose. At the same time, it can quickly and conveniently realize the operations of quickly shaking and exhausting air bubbles for a large number of samples, greatly improving the efficiency of sample pretreatment, and avoiding large errors in subsequent detection caused by inconsistent shaking times due to single shaking and exhausting air bubbles.

[0063] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
