[0033] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0034] like Figure 1-5 As shown, the utility model provides a laboratory reagent tube mixing device, including a power mechanism 1 and a fixing device for fixing the reagent tube 5. In order to mix more thoroughly, the power mechanism 1 includes a motor 101 and a connecting block 102, one side of the connecting block 102 is connected to the output rotating shaft 105 of the motor 101, and the fixing device is detachably fixed to the other side of the connecting block 102, so that the fixing device for fixing the reagent tube 5 is not on the same axis as the rotating position, and the fixing device is driven by the power mechanism 1 to mix under the action of centrifugal force.

[0035] In order to better drive the reagent tube 5 to mix and fix the reagent tube 5, the fixing device is a fixed column 2 provided with an inner groove 201, the inner groove 201 is open at least at the upper part, the reagent tube 5 is inserted and installed into the inner groove 201 along the opening, and the fixed column 2 is connected to the output rotating shaft 105 of the power mechanism 1, so that the fixed column 2 can make a circular motion driven by the power mechanism 1. In the laboratory online equipment, the liquid mixed with the reagent by the pump flows into the reagent tube 5, and the reagent tube 5 is placed inside the fixed column 2. Since the inner groove 201 is opened inside the fixed column 2, and the depth of the inner groove 201 is greater than or equal to two-thirds of the length of the reagent tube 5, the reagent tube will not fall out due to the swing of the power mechanism 1 when it is in the fixed column 2.

[0036] In order to enable the fixing device to complete shaking and mixing under different centrifugal forces through the device, the length of the connecting block 102 is greater than the width of the fixing device, so that the fixing device can be fixed at any position of the connecting block 102, so that mixing can be performed under the centrifugal forces of circles with different radii.

[0037] In order to facilitate the device to be fixed at any position and facilitate mixing of the reagent tube 5, a bracket 4 is also included, and the bracket 4 is fixed on the power mechanism 1. Specifically, the bracket 4 includes a first fixing part 401, the first fixing part 401 is fixed on the motor 101, and a through hole 404 is provided on the first fixing part 401 for the output rotating shaft 105 of the motor 401 to pass through. Second fixing parts 402 are arranged on both sides of the first fixing part 401, and a bending part 403 is arranged between the second fixing part 402 and the first fixing part 401, and the bending part 403 is perpendicular to the first fixing part 401 and the second fixing part 402 respectively. Such an arrangement can wrap the motor 101 between the bending parts 403, so that the first fixing part 401 and the second fixing part 402 can well fix the device at any position, and it is only necessary to fix the second fixing part 402 to the fixed part.

[0038] In order to facilitate the connection block 102 to be fixed on the motor 101, a connection hole 104 is opened on the connection block 102, and a hole for the output rotating shaft 105 of the motor 101 to pass through is opened at the bottom of the connection block 102. The connection block 102 is fixed to the output rotating shaft 105 of the motor 101 by passing a set screw through the connection hole 104.

[0039] In order to facilitate fixing the fixing column 2 on the connection block 102, the connection block 102 is provided with an adjustment hole 103, the fixing column 2 is provided with a fixing hole 202, and the length of the connection block 102 is greater than the width of the fixing column 2, so that the fixing column 2 can move in the horizontal direction of the connection block 102, so that the fixing hole 202 on the fixing column 2 can be fixed on any adjustment hole 103 on the connection block 102. The adjustment hole 103 is set as a countersunk hole.

[0040] In order to make the fixation between the fixing column 2 and the connecting block 102 more stable, there are at least two fixing holes 202 on the fixing column 2 , and the two fixing holes 202 are both fixed on the adjustment hole 103 .

[0041] The connecting block 102 is configured as a motor coupling, which is a mechanical connector mainly used to connect the motor to achieve power transmission and motion control. It is an interface for high-precision connection between the motor and the shaft, which can firmly connect the driving shaft and the driven shaft in different mechanisms to rotate together, and transmit motion and torque, so that the mixing effect is better.

[0042] In order to ensure that the fixing device can stop at a designated position after completing the mixing process, a sensor 3 is also included. The sensor 3 is configured as a diffuse reflection photoelectric switch. The sensor 3 is fixed on one side of the power mechanism 1, specifically on one side of the bracket 4. When the sensor 3 is powered on, the motor coupling is tangent to the signal light of the sensor 3, and the motor 101 stops rotating. This method can keep the motor 101 at the same position each time it stops.

[0043] How it works

[0044] like Figure 6-8 As shown, the fixing column 2 is fixed to a side of the connecting block 102 close to the output rotating shaft 105 of the motor 101 through the fixing hole 202. At this time, the fixing column 2 is driven by the power mechanism 1 to make a circle A rotation for mixing.

[0045] like Figure 9-10 As shown, when the fixing column 2 is fixed to the side of the connecting block 102 away from the output point of the motor 101 through the fixing hole 202, the fixing column 2 is driven by the power mechanism 1 to make a B-circle rotation for mixing.
