[0001] This utility model belongs to the field of test tube technology, specifically relating to a test tube rotating plate for liquid sample processing. Background Technology
[0002] Test tubes are common instruments in chemistry laboratories, used as reaction containers for small amounts of reagents. They are used at room temperature or when heated (preheating is necessary to prevent cracking). There are various types of test tubes, including ordinary test tubes, side-braced test tubes, and centrifuge tubes. Some test tubes have a rotating plate; however, when the test tube is rotated and tilted, the lack of a buffer structure at the bottom makes it prone to breakage. Utility Model Content
[0003] To address the problems mentioned in the background art, this utility model provides a test tube rotating plate for liquid sample processing. This solves the problem that some test tube rotating plates lack a buffer structure at the bottom when the test tubes are rotated and tilted, making them prone to collision and breakage.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a test tube rotating plate for liquid sample processing, comprising a base plate and a connecting box. A first motor is fixedly installed at the bottom of the base plate, and a first rotating shaft is provided at the output end of the first motor. A working plate is fixedly installed at the top of the first rotating shaft. A second motor is fixedly installed inside the working plate, and a second rotating shaft is provided at the output end of the second motor. A rotating rod is fixedly connected to one end of the second rotating shaft. A placement cylinder is fixedly installed on the inner wall of the rotating rod. A second return spring is fixedly installed on the inner wall of the working plate. A buffer plate is fixedly connected to the bottom of the second return spring. First return springs are fixedly installed on both sides of the placement cylinder. A connecting block is fixedly installed at one end of the first return spring. A sliding rod is fixedly installed on the inner side of the connecting block. A clamping plate is fixedly installed at one end of the sliding rod.
[0005] Preferably, a hook is fixedly installed on one side of the bottom of the base plate, and a limit plate is provided on one side of the inner wall of the base plate.
[0006] Preferably, the limiting plate is rotatably connected to the base plate, the limiting plate is located outside the connecting box, and the limiting plate is slidably connected to the connecting box.
[0007] Preferably, the surface of the base plate is configured in an I-shape, and the base plate is slidably connected to the connecting box.
[0008] Preferably, the buffer plate is located inside the working plate, and the buffer plate is slidably connected to the working plate, and the buffer plate is not connected to the first rotating shaft.
[0009] Preferably, one side of the clamping plate is located inside the placement cylinder, and the inner side of the clamping plate is arc-shaped.
[0010] Preferably, the slide rod is sleeved and connected to the first return spring, the slide rod is located inside the placement cylinder, and the slide rod is slidably connected to the placement cylinder.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] The test tube is placed inside the placement cylinder. The elastic force generated by the first return spring causes the clamping plate to slide and clamp the test tube. The first motor operates, causing the working plate to rotate for easy placement and clamping of multiple test tubes. The second motor operates, causing the placement cylinder to rotate and pour out the liquid inside the test tube. When the bottom of the test tube approaches the inside of the working plate, the elastic force generated by the second return spring causes the buffer plate to cushion the bottom of the test tube, reducing the possibility of breakage due to collision and improving the ease of use of this equipment.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-4 The present invention provides the following technical solution: a test tube rotating plate for liquid sample processing, comprising a base plate 1 and a connecting box 2. A first motor 5 is fixedly installed at the bottom of the base plate 1. A first rotating shaft 6 is provided at the output end of the first motor 5. A working plate 3 is fixedly installed at the top of the first rotating shaft 6. A second motor is fixedly installed inside the working plate 3. A second rotating shaft is provided at the output end of the second motor. A rotating rod 13 is fixedly connected to one end of the second rotating shaft. A placement cylinder 7 is fixedly installed on the inner wall of the rotating rod 13. A second return spring 14 is fixedly installed on the inner wall of the working plate 3. A buffer plate 9 is fixedly connected to the bottom of the second return spring 14. A first return spring 11 is fixedly installed on both sides of the placement cylinder 7. A connecting block 10 is fixedly installed at one end of the first return spring 11. A sliding rod is fixedly installed on the inner side of the connecting block 10. A clamping plate 12 is fixedly installed at one end of the sliding rod.
[0021] In a specific embodiment of this utility model, test tubes for liquid samples are placed inside the placement cylinder 7. The elastic force generated by the first return spring 11 causes the connecting block 10 to slide along the clamping plate 12 at one end of the sliding rod, clamping both sides of the test tubes on the inner wall of the placement cylinder 7. The first motor 5 operates, causing the first rotating shaft 6 to rotate the working plate 3, facilitating the placement and clamping of multiple test tubes. The second motor operates, causing the second rotating shaft to rotate the rotating rod 13, rotating the placement cylinder 7 and the test tubes, pouring out the liquid inside the test tubes. When the bottom of the test tube approaches the inside of the working plate 3, the elastic force generated by the second return spring 14 causes the buffer plate 9 to cushion the bottom of the test tube, reducing the risk of breakage due to collision and improving the ease of use of the device. The first motor 5 operates, causing the first rotating shaft 6 to rotate the working plate 3 in the opposite direction, pouring out the liquid inside the test tubes sequentially. This simple operation reduces the difficulty of the work.
[0022] In this embodiment: the installation hook 4 is used to place the wire connector of this device, so as to facilitate the connection of this device to an external power source. Rotate the limiting plate 8 to place the limiting plate 8 parallel to the base plate 1, and then take the base plate 1 out from the inside of the connecting box 2. Conversely, slide the base plate 1 into the inside of the connecting box 2, rotate the limiting plate 8 to place the limiting plate 8 and the base plate 1 in a cross shape, and limit the installation of the connecting box 2 and the base plate 1. The design is simple and reduces the production cost of this device.
[0023] The working principle and usage process of this utility model are as follows: After the utility model is installed, the hook 4 is installed to place the wire connector of the device, making it convenient to connect the device to an external power source. Rotate the limiting plate 8 to place the limiting plate 8 parallel to the base plate 1, and then remove the base plate 1 from the inside of the connecting box 2. Conversely, slide the base plate 1 into the inside of the connecting box 2, rotate the limiting plate 8 to place the limiting plate 8 and the base plate 1 in a cross shape, and limit the installation of the connecting box 2 and the base plate 1. Place the test tube for liquid sample into the inside of the placement cylinder 7. The elastic force generated by the first return spring 11 causes the connecting block 10 to drive the clamping plate 12 at one end of the slide rod to slide. The tension of the first return spring 11 itself causes the clamping plate 12 to clamp the test tube on both sides of the inner wall of the placement cylinder 7. The first motor 5 is set to operate. The first rotating shaft 6 drives the working plate 3 to rotate, facilitating the placement and clamping of multiple test tubes by the operator. The second motor drives the second rotating shaft to rotate the rotating rod 13, causing the placement cylinder 7 to rotate and empty the test tubes, pouring out the liquid inside. When the bottom of the test tube approaches the inside of the working plate 3, the elastic force generated by the second return spring 14 causes the buffer plate 9 to cushion the bottom of the test tube, reducing the risk of breakage due to collision and improving the ease of use. The first motor 5 drives the first rotating shaft 6 to rotate the working plate 3 in the opposite direction, sequentially emptying the liquid inside the test tubes. All electrical equipment in this device is powered by an external power source, and the motors, electric push rods, etc., are controlled by a PLC controller system.
[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
