Detailed Implementation

[0018] The technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1As shown, a test tube clamping and rotating mechanism includes: a first clamping member 1 and a second clamping member, the first clamping member 1 and the second clamping member cooperating to clamp and rotate the test tube; and a driving component, which jointly drives the first clamping member 1 and the second clamping member to clamp the test tube while rotating the test tube.

[0020] This invention uses a single drive component to simultaneously perform the clamping and rotation of the test tube, which not only reduces the spatial volume of the mechanism and lowers costs, but also reduces the difficulty of program design and improves the compatibility of the actions between the components due to the reduction of the drive component.

[0021] Furthermore, the drive assembly includes a motor 2 and a transmission mechanism; the first end of the output shaft of the motor 2 is connected to the first clamping member 1, which drives the first clamping member 1 to rotate; the second end of the output shaft of the motor 2 is connected to the transmission mechanism, which drives the second clamping member to move relative to the first clamping member 1 in the opposite direction or in the opposite direction, thereby cooperating with the first clamping member 1 to clamp or release the test tube.

[0022] The transmission mechanism includes a gear 3 that meshes with the second end of the output shaft of the motor 2; the upper end face of the gear 3 abuts against the second clamping member; the motor 2 drives the gear 3 to rotate relative to the second clamping member; the upper end face of the gear 3 includes a horizontal part 4 and a protrusion 5; the protrusion 5 is smoothly connected to the horizontal part 4; the motor 2 drives the first clamping member 1 and the gear 3 to rotate, when the horizontal part 4 of the rotating gear 3 abuts against the second clamping member, the first clamping member 1 and the second clamping member cooperate to clamp and rotate the test tube, when the protrusion 5 abuts against the second clamping member, the first clamping member 1 and the second clamping member move in opposite directions to release the test tube.

[0023] This utility model uses a gear 3 with a protrusion 5 as a transmission mechanism to drive the movement of the second clamping member. The structure is simple and the cost is low. In addition, the gear has high hardness, wear resistance, and is easy to install, which is beneficial to the later maintenance of the device.

[0024] Furthermore, it also includes a mounting frame 6; the second clamping member is rotatably mounted on the mounting frame 6. The second clamping member includes a support part 7, an upper support frame 8, a lower support frame 9, and an idler wheel assembly 10; the upper support frame 8 and the lower support frame 9 are respectively horizontally mounted at both ends of the support part 7; the support part 7 is rotatably mounted on the mounting frame 6 via a rotating shaft 11; the idler wheel assembly 10 is rotatably mounted on the end of the upper support frame 8 near the first clamping member 1; a rotating bracket 12 is provided at the end of the lower support frame 9 away from the support part 8, and a rotating wheel 13 is provided at the bottom of the rotating bracket 12, the rotating wheel 13 abutting against the upper end face of the gear 3; the end of the lower support frame 9 away from the support part 7 is mounted on the mounting frame 6 via a tension spring 14, the tension spring 14 provides the second clamping member with abutting force towards the upper end face of the gear 3; when the horizontal part 4 of the gear 3 abuts against the second clamping member, the tension force of the tension spring 14 on the second clamping member can be converted into a clamping force towards the test tube.

[0025] The first clamping component includes a rotating wheel; the rotating wheel is fixedly installed at the first end of the output shaft of the motor 2 and is positioned opposite to the idler wheel assembly 10; a test tube moving channel is formed between the rotating wheel and the idler wheel assembly 10.

[0026] In this embodiment, the idler wheel assembly 1 uses two conventional passively rotating rollers. When the rotating wheel and the idler wheel assembly 10 clamp the test tube, the rotation of the rotating wheel causes the idler wheel assembly 10 to rotate passively, thereby driving the test tube between them to rotate.

[0027] When the output shaft of the motor 2 rotates, the rotating wheels and gears 3 at both ends of the output shaft rotate simultaneously. During rotation, when the protrusion 5 of the gear 3 abuts against the rotating wheel 13, the protrusion 5 can support its rotating bracket 12 to rise, causing the support 7 to rotate in the opposite direction relative to the rotating wheel. The distance between the rotating wheel and the idler wheel assembly 10 increases, and the test tube enters the moving channel between the rotating wheel and the idler wheel assembly 10. The gear 3 continues to rotate. During rotation, when the horizontal part 4 of the gear 3 abuts against the rotating wheel 13, the rotating bracket 12 descends from the protrusion 5 to the horizontal part 4, causing the support 7 to rotate in the opposite direction relative to the rotating wheel. The distance between the rotating wheel and the idler wheel assembly 10 decreases, forming a clamping force on the test tube between them. At this time, the motor 2 continues to rotate, and the rotating wheel 13 at the bottom of the rotating bracket 12 continues to move on the horizontal part 4 of the gear 3, so that the rotating wheel and the idler wheel assembly 10 can drive the test tube to rotate while clamping it.

[0028] Furthermore, the motor 2 of this utility model is a dual-output-shaft stepper motor; the two ends of the output shaft of the motor 2 can rotate simultaneously, thereby driving the first clamping member 1 and the second clamping member to move in opposite directions or in the opposite direction.

[0029] This invention has a simple structure. It uses a single motor to not only enable the first and second clamping members to move towards each other or react with each other, but also to enable the first clamping member to rotate, thereby driving the test tube to rotate. This greatly reduces the use of motors, and the simple structure makes it much easier to debug the instrument and reduce the maintenance cost of the instrument.

[0030] Meanwhile, this utility model also discloses a sample analysis system, including the aforementioned test tube clamping and rotating mechanism. By reducing the use of a motor in the test tube clamping and rotating mechanism, the sample analysis system not only reduces the production cost of the analysis system but also facilitates the debugging and installation of the instrument.

[0031] The above are merely embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model shall be included within the scope of the claims of this utility model pending approval.
