DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0029] The present application embodiment provides a test tube shaking device, such as Figure 1 and Figure 2As shown, it includes a placement table 1 and a rotating table 2 arranged in parallel, the rotating table 2 is located below the placement table 1 and is rotated around the axis of the placement table 1; when swinging, the rotating table 2 is eccentrically arranged with the placement table 1, and the eccentric distance is adjustable; a plurality of clamping units 11 are arranged in a circular array on the placement table 1, and the clamping units 11 and the placement table are ball-hinged, and a through hole 115 is arranged inside the clamping unit 11 for passing a test tube; matching holes 21 corresponding to the clamping units 11 are opened on the surface of the rotating table 2.

[0030] Specifically, the clamping unit 11 arranged on the placement table 1 is used to clamp the upper end of the test tube containing the reagent to be shaken, and the bottom of the test tube fits into the matching hole opened on the surface of the rotating table 2; the rotating table 2 and the placement table 1 are eccentrically arranged, so that the rotating table 2 can rotate around the axis of the placement table 1, thereby driving the test tube to rotate around the axis at a certain angle, and the eccentric distance between the rotating table 2 and the placement table 1 can be adjusted; when the eccentric distance becomes larger, the amplitude of the rotation of the rotating table 2 around the axis of the placement table 1 becomes larger, that is, the amplitude of shaking becomes larger; when the eccentric distance becomes smaller, the amplitude of shaking can be reduced; a number of clamping units 11 are arranged on the placement table 1, and the matching holes 21 opened on the rotating table 2 correspond to the clamping units 11 one by one, so that batches of test tubes can be shaken at one time. Through the above settings, the device can realize automatic batch shaking of reagents in test tubes and automatically control the amplitude of shaking.

[0031] Preferably, the inner wall of the matching hole 21 can be set to a spherical shape or other shapes that can adapt to the bottom of the test tube. In this embodiment, the inner wall of the matching hole 21 is set to a spherical shape. When the test tube rotates, the matching hole 21 can always fit with the bottom of the test tube to avoid motion interference at the bottom of the test tube, so that the test tube rotates smoothly.

[0032] Specifically, Figure 2 As shown, the clamping unit 11 includes a spherical clamping seat 111, a through hole 115 is opened inside the clamping seat 111, and two clamping plates 112 are arranged inside the through hole 115 along the axial direction. The two clamping plates 112 are symmetrically arranged relative to the axis of the through hole 115 and are used to clamp the test tube; a guide rod 113 is connected to one side of the clamping plate 112, and the other end of the guide rod 113 is inserted into the clamping seat 111, and the guide rod 113 is movably arranged along the axis. A clamping spring 114 is sleeved on the guide rod 113, and one end of the clamping spring 114 abuts against the clamping seat 111, and the other end abuts against the clamping plate 112; when the clamping spring 114 is in a natural state, the two clamping plates 112 are retracted to each other. When the test tube is placed, the test tube presses the two clamping plates against the clamping spring 114 and contracts along the guide rod 113 toward the inner wall of the through hole 115. After the test tube is placed, the test tube is clamped by the clamping plates 112 and the clamping spring 114 to prevent the test tube from falling out of the clamping unit 11 when the test tube rotates, thereby improving the stability of the test tube during rotation.

[0033] Preferably, the shape of the clamping plate 112 can be set to be V-shaped, arc-shaped or other shapes that can adapt to the outer wall of the test tube. In this embodiment, it is set to be arc-shaped, which can better fit the outer wall of the test tube, improve the clamping stability, and further improve the stability of the test tube when rotating.

[0034] Specifically, Figure 3 As shown, the inner wall shape of the through hole 23 opened on the placement table 1 is adapted to the spherical clamping seat 111, and the outer wall of the clamping seat 111 is in spherical contact with the inner wall of the through hole 23, so that the clamping seat 111 can rotate in coordination with the rotation of the test tube. The outer wall of the clamping seat 111 is in spherical contact with the inner wall of the through hole 23. When the spherical surfaces are in contact, the friction force is small, the wear is small, and the operation is smooth, which increases the service life of the device and the stability of the test tube when it rotates.

[0035] like Figure 1 As shown, three or more movable rods 4 are arranged between the placing table 1 and the rotating table 2. The movable rods 4 are parallel to each other. Both ends of the movable rods 4 are universally connected to the bottom of the placing table 1 and the top of the rotating table 2. Specifically, the universal connection includes a ball hinge structure and a universal joint connection structure. This embodiment adopts a ball hinge structure.

[0036] Specifically, Figure 1 and Figure 4 As shown, a rotating device 5 is provided below the rotating table 2, which includes a rotating column 51 coaxially arranged with the placing table 1, a rotating rod 521 is vertically connected to the upper end of the rotating column 51, a matching rod 522 is provided at the distal end of the rotating rod 521, and an annular groove 22 is provided at the bottom of the rotating table 2, the matching rod 522 is matched in the annular groove 22, and the distance from the matching rod 522 to the axis of the rotating column 51 is greater than the radius of the annular groove 22. After the test tube is installed, the rotating column 51 rotates to drive the rotating rod 521 to rotate. Since the matching rod 522 provided at the distal end of the rotating rod 521 is matched in the annular groove 22, and the distance from the matching rod 522 to the axis of the rotating column 51 is greater than the radius of the annular groove 22, that is, the rotating table 2 is eccentrically arranged with the placing table 1, the matching rod 522 moves in the annular groove 22, thereby realizing the rotation of the rotating table 2 around the axis of the placing table 1.

[0037] Specifically, Figure 4As shown, the upper end of the rotating column 51 is coaxially provided with a connecting seat 52 with the rotating rod 521, and the rotating rod 521 is movably inserted in the connecting seat 52, and the rotating rod 521 is movably arranged along the axis. When the rotating rod 521 extends outward along the axis, the distance between the matching rod 522 and the axis of the rotating column 51 becomes larger, that is, the eccentric distance between the rotating table 2 and the placing table 1 becomes larger, so that the amplitude of shaking the test tube becomes larger, and when the rotating rod 521 shrinks inward along the axis, the distance between the matching rod 522 and the axis of the rotating column 51 becomes smaller, that is, the eccentric distance between the rotating table 2 and the placing table 1 becomes smaller, so that the amplitude of shaking the test tube becomes smaller. The reagent in the test tube can be shaken evenly with different amplitudes by the extension and retraction of the rotating rod.

[0038] Specifically, Figure 5 As shown, the interior of the rotating column 51 is hollow, and the rotating column 51 is partially opened on one side facing the rotating rod 521. An adjustment block 524 is slidably fitted inside the rotating column 51. The rotating rod 521 is rotatably connected to one end of a rotating plate 53 through a first rotating shaft 523, and the other end of the rotating plate 53 is rotatably connected to the adjustment block 524 through a second rotating shaft 526. The first rotating shaft 523 and the second rotating shaft 526 are parallel to each other and perpendicular to the axis of the rotating rod 521. A linear mechanism 6 is provided below the rotating column 51, and the movable end of the linear mechanism 6 is used to drive the adjustment block 524 to move along the axis of the rotating column 51. The linear mechanism 6 used in this embodiment is a linear cylinder. When the rotating column 51 rotates, the movable end of the linear cylinder drives the adjustment block 524 to move upward along the axis of the rotating column 51. Under the action of the rotating plate 53, the rotating rod 521 extends outward along the axis, thereby increasing the rotation amplitude of the rotating table 2. When the movable end of the linear cylinder moves downward along the axis of the rotating column 51, the adjustment block 524 also moves downward due to gravity, and the rotating rod 521 contracts inward along the axis, thereby reducing the rotation amplitude of the rotating table 2. Through the above settings, effective control of the shaking amplitude can be achieved.

[0039] Specifically, Figure 1 and Figure 5 As shown, a return spring 525 is provided inside the rotating column 51, one end of the return spring 525 is connected to the top of the rotating column 51, and the other end is connected to the top of the adjustment block 524. When the return spring 525 is in a natural state, the rotating table 2 is coaxial with the placement table 1. Through the setting of the return spring 525, when the adjustment block moves upward along the axis of the rotating column 51, it can automatically restore its position, and when the return spring 525 is in a natural state, the rotating table 2 is coaxial with the placement table 1, that is, the rotating table 2 stops rotating, making it more convenient to install the test tube.

[0040] Specifically, Figure 1 and Figure 5As shown, a gear ring 54 is fixedly sleeved on the rotating column 51, and a driving motor 7 is arranged below the rotating column 51. The movable end of the driving motor 7 is vertically upward and connected to a gear 71 meshing with the gear ring 54. The gear ring 54 is sleeved on the rotating column 51, and the driving motor 7 is arranged on one side of the rotating column 51. The movable end of the driving motor 7 is connected to the gear 71 meshing with the gear ring 54, so that the rotating column 51 and the driving end of the driving motor 7 are staggered by a certain distance for installing the linear mechanism 6.

[0041] Specifically, Figure 1 and Figure 5 As shown, the placing table 1 is mounted on a base 3 through a fixing frame 9, and the rotating table 2 is located between the placing table 1 and the base 3; a door frame 8 is mounted on the base 3, and a limit hole is opened on the top of the door frame 8, and the rotating column 51 is matched in the limit hole; the driving motor 7 and the linear mechanism 6 are both installed on the base 3. Through the above settings, the device forms an integral structure, which is convenient for movement.

[0042] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
