Description

Technical Field

[0001] This utility model belongs to the technical field of chemical experimental equipment, and more specifically, relates to an oscillating mixing structure for chemical analysis. Background Technology

[0002] In chemical analysis and testing, researchers often need to mix different samples with reagents in test tubes, typically by hand-shaking the tubes. However, when analyzing batches of samples, this manual operation becomes significantly time-consuming. For example, processing 72 samples in a digestion experiment could take several hours, and the repetitive nature of the action can lead to operator fatigue, further reducing efficiency. Moreover, fluctuations in manual shaking time can cause variations in experimental conditions, ultimately affecting the accuracy of subsequent data analysis.

[0003] Currently, there are fully automated chemical analysis instruments on the market that can process reagents in batches. These instruments can achieve precise liquid addition, mixing, and reaction monitoring through programmed control. However, these large instruments are relatively expensive and complex to operate, making them unsuitable for use in ordinary chemical analysis laboratories. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a simple structure with a reasonable structural design that can improve the reagent mixing efficiency, so as to be used in ordinary chemical analysis laboratories.

[0005] To achieve the above objectives, the inventor, drawing on years of experience in chemical analysis, and through extensive design, repeated experimentation, and improvement, finally obtained the following technical solution: an oscillating mixing structure for chemical analysis, comprising a base, a vertical support plate fixed to the symmetrical edge of the top surface of the base, a support plate provided on the upper part of the base, a plurality of test tube insertion holes for placing test tubes provided on the support plate, and a convex shaft integrally formed in the middle of the symmetrical side of the support plate, the convex shaft being set on the upper part of the vertical support plate through a bearing;

[0006] A limiting plate is provided below the support plate. The symmetrical ends of the limiting plate are connected to the convex shaft by a support rod. The top surface of the limiting plate is provided with several bottom-closed cavities for inserting into the bottom of the test tube.

[0007] One of the vertical support plates has a protrusion fixed on the upper side wall, a drive motor is fixed on the protrusion, a crank arm is fixed on the main shaft of the drive motor, and a transmission arm is provided between the crank arm and the side of the limiting plate. One end of the transmission arm is sleeved on the crank arm through a ring, and the other end is rotatably connected to the side of the limiting plate through a pin.

[0008] When the drive motor starts, it drives the limiting plate to swing back and forth around the convex shaft via the crank arm and transmission arm.

[0009] A further preferred embodiment is that a counterweight is embedded in the bottom surface of the base.

[0010] A further preferred embodiment is that a power supply is fixed inside the base, and an electrical cable channel is provided inside the vertical support plate, with the power supply and the power supply for the drive motor passing through the electrical cable channel.

[0011] A further preferred embodiment is that the base is provided with a motor start / stop switch.

[0012] A further preferred embodiment is that: a speed control box is fixed to the output end of the drive motor, and a speed control knob connected to the speed control box is provided on the base.

[0013] A further preferred embodiment is that the limiting plates of the support plate are all made of acrylic sheets.

[0014] A further preferred embodiment is that the depth of the insertion cavity is 1-3 cm, and a rubber pad layer is provided on the inner wall of the insertion cavity.

[0015] A further preferred embodiment is that the bottom of the test tube is inserted into the cavity and the rubber pad is squeezed to limit its position.

[0016] A further preferred embodiment is that the support rod is a telescopically adjustable support rod.

[0017] This invention has several advantages: It features a simple structure with a support plate and a limiting plate on the same convex shaft. When a test tube is inserted, the upper and lower parts of the tube are limited. A drive motor, in conjunction with a transmission arm, allows the support plate and limiting plate to swing when the motor operates, thus achieving mixing of the reagents within the test tube. Furthermore, it enables simultaneous mixing of multiple test tubes, facilitating cross-sectional comparison of data from multiple samples and yielding more reliable analytical results.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 3 As shown, an oscillating mixing structure for chemical analysis includes a base 1, a vertical support plate 2 fixed to the symmetrical edge of the top surface of the base, a support plate 3 provided on the upper part of the base, and a plurality of test tube insertion holes 4 for placing test tubes provided on the support plate. A convex shaft 5 is integrally formed in the middle of the symmetrical side of the support plate, and the convex shaft is set on the upper part of the vertical support plate through a bearing. In this embodiment, the length of the convex shaft 5 can be set as needed, and in actual application, the length of the support plate is less than the width between the two vertical support plates, while the test tube insertion holes can be set as needed, mainly for inserting test tubes.

[0025] In this embodiment, a limiting plate 6 is provided below the support plate. In actual application, the distance between the limiting plate and the top surface of the base is greater than half the width of the limiting plate, meaning that the limiting plate will not be affected by the base when swinging. The symmetrical ends of the limiting plate are connected to the convex shaft via support rods 7, and the top surface of the limiting plate is provided with several bottom-closed insertion cavities 8 for inserting the bottom of the test tube. The depth of the insertion cavity is 1-3 cm, and a rubber pad layer 19 is provided on the inner wall of the insertion cavity. The bottom of the test tube is inserted into the insertion cavity and the rubber pad layer is squeezed for limiting. When the bottom of the test tube is inserted, the rubber pad layer can limit the insertion and also prevent damage to the test tube when swinging.

[0026] In practical applications, the support rod is a telescopic adjustable support rod, which can adjust the height between the limiting plate and the support plate as needed to meet the requirements of test tubes of different lengths. The support rod can be an electrically telescopic support rod, or a manually telescopic support rod that is adjusted in height by means of a bottom cylinder, an insertion rod, and a locking screw. The insertion rod is inserted into the bottom cylinder and locked in place by the locking screw on the side wall of the bottom cylinder.

[0027] In this embodiment, a protrusion 9 is fixed to the upper side wall of one of the vertical support plates, and a drive motor 10 is fixed to the protrusion. A crank arm 11 is fixed to the main shaft of the drive motor. A transmission arm 12 is provided between the crank arm and the side of the limiting plate. One end of the transmission arm is sleeved on the crank arm through a ring 13, and the other end is rotatably connected to the side of the limiting plate through a pin 14. When the drive motor is started, it drives the limiting plate to swing back and forth around the convex shaft through the crank arm and the transmission arm. In actual application, if the ring becomes loose or falls off, the limiting plate can be fixed at the end of the crank arm by screws or buckles, which is a conventional operation in the prior art. The transmission arm is a metal structural component, and since its length is fixed, the limiting plate can swing relative to the convex shaft under the action of the crank arm.

[0028] In this embodiment, the counterweight 15 embedded in the bottom surface of the base ensures the center of gravity of the overall structure, preventing tipping or swaying. Simultaneously, a power supply is fixed inside the base, and a wiring channel is provided within the vertical support plate, through which the power supply and the power source for the drive motor pass. A motor start / stop switch 16 is provided on the base. The power supply can be a battery or a mains plug, etc. The wiring channel can be a circular hole or a concave groove on the outer wall with a cover, primarily for concealing and connecting the wires, preventing damage, and also improving the aesthetics.

[0029] In this embodiment, a speed control box 17 is fixed to the output end of the drive motor, and a speed control knob 18 connected to the speed control box is provided on the base. The swing speed can be adjusted as needed. The speed control box is a conventional structure in the prior art, and it is simply applied in this way.

[0030] In this embodiment, the limiting plates of the support plate are preferably acrylic plates.

[0031] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0032] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
