Description

Technical Field

[0001] This utility model relates to the field of shaking equipment technology, and in particular to a test tube uniform shaking device. Background Technology

[0002] In medical testing, it is often necessary to shake the samples in test tubes to ensure uniform distribution and improve testing accuracy. However, traditional shaking methods rely mainly on manual shaking by the testing personnel, which is not only time-consuming and labor-intensive but also produces inconsistent results and can easily lead to sample spillage.

[0003] To address the aforementioned issues, a search revealed Chinese patent application CN202022571603.0, which discloses a test tube shaking device for chemical testing. This device includes a housing, a top cover, a first rotating shaft, a first gear, a second gear, a second rotating shaft, a third gear, a drive motor, a mounting plate, clamping components, a stop component, and control buttons. This patent reduces the workload of laboratory technicians and allows for temperature adjustment of the reaction environment as needed, improving the accuracy of comparative test data. However, the aforementioned patent still has the following shortcomings: due to the limited number and fixed structure of the clamping components within the shaking chamber, it is impossible to flexibly increase or decrease the number of test tubes according to testing needs in practical applications. This results in the device being unable to meet the requirements for high sample volumes and a decreased utilization rate for low sample volumes. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0035] Example 1

[0036] A test tube shaking device, such as Figure 1-5 As shown, the device includes a base 1, and a control panel 3 for controlling the shaking speed of the device is fixed to the outer circumference of the base 1 by bolts; a disc 2 is connected to the inner circumference of the top of the base 1 by a rotating shaft, and a U-shaped frame 4 is fixed to the top outer wall of the disc 2 by bolts. A multi-layer test tube storage component is placed inside the U-shaped frame 4 by a detachable connecting assembly.

[0037] Furthermore, a drive assembly is provided on the inner wall of the base 1 located below the disc 2. The drive assembly includes a motor 201 fixed to the inner wall of the base 1 by bolts, a support plate 101 fixed to the inner wall of the base 1 by bolts, a cam 202 rotatably connected to one side of the support plate 101, a semi-circular plate 204 fixed to the outer wall of the bottom of the disc 2 by bolts, and two springs A203 symmetrically welded to the corresponding sides of the disc 2 and the base 1. The output end of the motor 201 is connected to one end of the cam 202 through a coupling. The cam 202 meshes with the outer wall of the semi-circular plate 204. The motor 201 is electrically connected to the control panel 3.

[0038] Preferably, the two springs A203 and the rotating shaft are arranged in opposite directions, such as the springs A203 being arranged front and back, and the rotating shaft being arranged horizontally;

[0039] During operation, the motor 201 is started via the control panel 3, which in turn drives the cam 202 to rotate. As the cam's shape changes, it pushes against the semi-circular plate 204, causing the disc 2 to swing back and forth around the rotation axis. The two springs A203 effectively improve the stability of the disc 2 during its back-and-forth swing. Furthermore, by controlling the rotation speed of the motor 201, the shaking mode (fast or slow) can be set according to the type of sample in the test tube, ensuring the mixing effect of the sample and reagents in the test tube. This makes the device easy to use and guarantees the quality of medical testing.

[0040] Preferably, the bottom outer wall of the base 1 is bonded with an anti-slip pad 12 to improve the stability of the equipment when it is placed flat.

[0041] Furthermore, the test tube storage component includes a storage tray 5, a plurality of placement holes 10 arranged in a ring array on the inner circumference of the storage tray 5, and auxiliary fixing structural components.

[0042] Preferably, a silicone ring 1001 is welded to the inner circumference of the placement hole 10 to increase the clamping force when the test tube is placed in the placement hole 10, prevent the test tube from falling off during shaking, and also clamp test tubes of different diameters.

[0043] In a further preferred embodiment, the auxiliary fixing structure includes two guide rods 11 inserted into the inner circumference of the storage tray 5, a support plate 6 welded to the bottom of the two guide rods 11, and a spring B1101 sleeved on the outer circumference of the guide rods 11. The two ends of the spring B1101 are welded to the corresponding side of the support plate 6 and the storage tray 5. Multiple test tubes to be shaken are inserted into different placement holes 10 from above and fixed. The support plate 6 below abuts against the bottom of the test tubes under the action of the spring B1101 to support the test tubes from the bottom, preventing the test tubes from falling during shaking and improving the safety of the operation.

[0044] Preferably, a silicone pad 601 is adhered to the top outer wall of the tray 6, which contacts the bottom of the test tube to prevent the test tube from making direct hard contact with the storage tray 5 and thus causing damage.

[0045] Furthermore, the connecting assembly includes multiple sets of slots 401 arranged vertically on one side of the U-shaped frame 4, and two symmetrically arranged blocks welded to the outer circumference of the storage tray 5 and adapted to the slots 401. Depending on the number of test tubes to be shaken, an appropriate number of storage trays 5 can be inserted into the slots 401 on the U-shaped frame 4 using the blocks, thereby making the storage trays 5 and the U-shaped frame 4 fixedly connected, which is easy to assemble and disassemble and has a stable structure.

[0046] Preferably, a rubber plate is welded to one side of the outer wall of the card block to increase the friction when the card block contacts the card slot 401, and to prevent the storage tray 5 from falling off the U-shaped frame 4 during operation.

[0047] Working principle: Depending on the number of test tubes to be shaken, select an appropriate number of storage trays 5, and then insert multiple test tubes to be shaken into different placement holes 10 from above and fix them. The bottom plate 6 under the action of spring B1101 abuts against the bottom of the test tubes. Then, the storage tray 5 containing the test tubes is inserted into the slot 401 on the U-shaped frame 4 by the locking block, so that the storage tray 5 and the U-shaped frame 4 form a fixed connection.

[0048] During operation, the motor 201 is started via the control panel 3, which in turn drives the cam 202 to rotate. As its shape changes, the cam pushes against the semi-circular plate 204, causing the disc 2 to swing back and forth around the rotation axis. The two springs A203 effectively improve the stability of the disc 2 during its back-and-forth swing. Furthermore, by controlling the rotation speed of the motor 201, the shaking mode (fast or slow) can be set according to the type of sample in the test tube, ensuring the mixing effect of the sample and reagents in the test tube.

[0049] Example 2

[0051] Preferably, the folding cover 8 can be made of polyester / nylon base fabric or other materials, which have good light-blocking properties;

[0052] Preferably, the annular plate 9 is made of metal such as iron, and it forms a magnetic structure with the magnet 901 fixed to the top outer wall of the base 1 by bolts. Pulling down the annular plate 9 pulls the folding cover 8 to extend until the annular plate 9 and the magnet 901 adhere and attract each other, so that the multi-layer storage tray 5 is completely covered within the enclosure of the folding cover 8. During operation, the U-shaped frame 4 and its upper structure swing left and right within the enclosure of the folding cover 8 under the drive of the disc 2, so as to achieve uniform shaking of the sample. This structure is suitable for test tube samples that need to be shaken in the dark, to prevent light from decomposing components and causing detection errors, and to improve the functionality of the equipment.

[0053] Furthermore, the bottom surface of the top cover 7 is welded with a post 801, and the inner circumference of the annular plate 9 is provided with a socket 13 that matches the post 801. When there is no need to block the light, the annular plate 9 can be lifted to fold and retract the folding cover 8 until the post 801 is inserted into the socket 13, thereby completing the storage of the folding cover 8, which is relatively convenient.

[0054] Working principle: Pull down the annular plate 9 to extend the folding cover 8 until the annular plate 9 adheres to the magnet 901, thereby completely covering the multi-layer storage tray 5 within the coverage area of ​​the folding cover 8. During operation, the U-shaped frame 4 and its upper structure swing left and right within the coverage area of ​​the folding cover 8 under the drive of the disc 2, so as to achieve uniform shaking treatment of the sample. When there is no need for light blocking, the annular plate 9 can be lifted to fold and retract the folding cover 8 until the insertion post 801 is inserted into the insertion hole 13, thereby completing the storage of the folding cover 8.
