Description

Technical Field

[0001] The utility model belongs to the technical field of test tube supports, and more specifically, relates to a device for quickly mixing test tube reagents. Background Art

[0002] When conducting experiments, the reason for mixing the reagents in the test tube is to ensure that the reagents react fully to obtain accurate experimental results. Reagent mixing is usually accelerated by shaking, stirring, or oscillating. After mixing, the reagents can react more quickly and evenly, thereby improving the efficiency and accuracy of the experiment. Reagents usually exist in the form of liquids or powders, and they contain different chemical substances or solutes. Mixing the reagents can make the different components in them come into full contact and increase the chance of reaction between them. If the reagents are not mixed sufficiently, some components may be locally excessive while other components may not be able to participate in the reaction, resulting in inaccurate results.

[0003] Shaking the test tube is a common mixing method. It is achieved by manually shaking the test tube or using devices such as vibrators, which can quickly mix the reagents together, especially suitable for a small amount of reagents or situations where rapid mixing is required. Manually shaking the test tube requires manual operation, so it is a labor-intensive task for experimenters. In the case of a large number of test tubes to be processed, this may increase the workload, leading to fatigue and inconvenience. The mixing effect of hand-shaking the test tube depends on the strength and frequency of the operator, so it is difficult to ensure that the mixing effect of each test tube is exactly the same. This may lead to inconsistencies in the test results, especially when conducting tests among multiple experimenters.

[0004] In summary, hand-shaking the test tube has the problems that experimenters are prone to fatigue and the reagent mixing effect is poor. Content of the Utility Model

[0005] In view of this, the utility model provides a device for quickly mixing test tube reagents, which can solve the problems that experimenters are prone to fatigue and the reagent mixing effect is poor when hand-shaking the test tube.

[0006] The utility model is implemented as follows:

[0007] The utility model provides a device for quickly mixing test tube reagents, which includes a support frame. The support frame is in an inverted C-shaped structure. A power mechanism is fixedly connected to the lower bottom surface of the support frame. A fixing plate is slidably connected to the lower bottom surface of the support frame. The fixing plate is located on the right side of the power mechanism. The left side wall of the support frame is fixedly connected to the fixing plate through a spring. The power mechanism is used to drive the fixing plate to make a reciprocating motion along the lower bottom surface of the support frame. A clamp is fixedly connected to the fixing plate. The clamp is used to clamp the test tube. A leak-proof mechanism is slidably connected to the fixing plate. The leak-proof mechanism is movably connected to the test tube. The leak-proof mechanism is used to prevent the reagents in the test tube from leaking out.

[0008] The technical effects of a test tube reagent rapid mixing device provided by the utility model are as follows: the power mechanism can drive the fixed plate and the clamp to reciprocate, and can evenly mix the liquid reagents in the test tube to ensure that the various components are fully contacted and mixed, thereby improving the reaction efficiency. The oscillation generated by the reciprocating motion promotes the interaction between the reagents and accelerates the rate of chemical reactions. This is particularly beneficial for experiments that require rapid reactions. Reciprocating test tube oscillation is usually faster and more effective than manual mixing, so it can save experimental time and improve experimental efficiency. The clamp can firmly clamp the test tube to prevent the test tube from sliding or tilting during the experiment, thereby ensuring the safety of the experimental operation. The clamp can make the experimental process more efficient because they can fix multiple test tubes at the same time, reducing the time that the experimenter needs to fix the test tubes one by one. The leak-proof mechanism can prevent the test tube from overflowing the reagent during the oscillation process, thereby reducing the liquid splashing, burns or other safety issues that may be caused in the experiment. Avoiding test tube overflow can protect the experimental equipment from reagent contamination, extend the service life of the equipment and reduce cleaning work.

[0009] On the basis of the above technical solution, the test tube reagent rapid mixing device of the utility model can also be improved as follows:

[0010] Among them, the power mechanism includes a servo motor and a disc, the servo motor is fixedly connected to the lower bottom surface of the support frame, the output shaft of the servo motor is fixedly connected to the disc, the disc is a cylindrical structure, and the distance between the connection between the output shaft of the servo motor and the disc and the center of the bottom surface of the disc is 1 / 2-1 / 3 of the radius of the bottom surface of the disc.

[0011] The beneficial effect of adopting the above-mentioned improvement scheme is: because the output shaft of the servo motor does not coincide with the center of the disc, the disc will produce eccentric motion, and the eccentric motion will cause the fixed plate in contact with the disc to reciprocate under the rotation of the disc, thereby oscillating and mixing the test tube.

[0012] Furthermore, the fixed plate includes a first fixed plate and a second fixed plate, the first fixed plate is fixedly connected to the second fixed plate, the angle between the first fixed plate and the second fixed plate is a right angle, a plurality of cylindrical support rods are arranged inside the first fixed plate, the first fixed plate is fixedly connected to one end of the spring, the other end of the spring is fixedly connected to the left side wall of the support frame, and the second fixed plate is slidably connected to the lower bottom surface of the support frame.

[0013] The beneficial effect of adopting the above-mentioned improvement scheme is that the spring can drive the fixing plate to reset, so that the fixing plate performs reciprocating motion under the combined action of the power mechanism and the spring.

[0014] Furthermore, the clamp includes a fixed seat, a rubber pad and a storage cavity. A plurality of the fixed seats are fixedly connected to the second fixed plate. The fixed seats are evenly arranged on the second fixed plate. A storage cavity is provided inside the fixed seat. A rubber pad is fixedly connected inside the storage cavity. The rubber pad is used to deform and clamp the test tube.

[0015] Furthermore, the leakage prevention mechanism includes a sliding plate, a sleeve, a protrusion, a groove, a sealing gasket and a disposable waterproof membrane. The sliding plate is a rectangular structure. The sleeve is fixedly connected to the left side wall of the sliding plate. The sleeve is sleeved on a cylindrical support rod inside the first fixed plate. The sleeve is slidably connected to the first fixed plate. A plurality of the protrusions are fixedly connected to the lower bottom surface of the sliding plate. The protrusions are evenly arranged on the lower bottom surface of the sliding plate.

[0016] Furthermore, the convex block is provided with the groove, the groove is a circular ring structure, the sealing gasket is movably connected inside the groove, and the sealing gasket is covered with a plurality of disposable waterproof membranes outside.

[0017] The beneficial effects of adopting the above-mentioned improved solution are as follows: the disposable waterproof membrane can effectively seal the tube mouth of the test tube to prevent the reagent from leaking or volatilizing during the experiment. This helps to keep the laboratory work surface clean and avoid the reagent from interfering with or contaminating the experimental results. The waterproof membrane can prevent dust, microorganisms or other contaminants in the external environment from entering the test tube, thereby maintaining the purity of the reagent. This helps to ensure the accuracy and repeatability of the experimental results.

[0018] Furthermore, the position of the protrusion corresponds to that of the fixing seat.

[0019] Furthermore, the groove is adapted to the mouth of the test tube.

[0020] Furthermore, a silicone pad is fixedly connected to the inner side of the right side wall of the support frame.

[0021] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the silicone pad can absorb vibration and impact, reducing the risk of damage to the test tube. The test tube may break or crack during vibration or impact, and the silicone pad can reduce the possibility of this happening and extend the service life of the test tube.

[0022] Furthermore, the disk is in contact with the first fixing plate.

[0023] Compared with the prior art, the utility model provides a test tube reagent rapid mixing device with the following beneficial effects: the power mechanism can drive the fixed plate and the clamp to reciprocate, and can evenly mix the liquid reagents in the test tube to ensure that the various components are fully contacted and mixed, thereby improving the reaction efficiency. The oscillation generated by the reciprocating motion promotes the interaction between the reagents and accelerates the rate of chemical reactions. This is particularly beneficial for experiments that require rapid reactions. Reciprocating test tube oscillation is usually faster and more effective than manual mixing, so it can save experimental time and improve experimental efficiency. The clamp can firmly clamp the test tube to prevent the test tube from sliding or tilting during the experiment, thereby ensuring the safety of the experimental operation. The clamp can make the experimental process more efficient because they can fix multiple test tubes at the same time, reducing the time that the experimenter needs to fix the test tubes one by one. The leak-proof mechanism can prevent the test tube from overflowing the reagent during the oscillation process, thereby reducing the liquid splashing, burns or other safety issues that may be caused in the experiment. Avoiding test tube overflow can protect the experimental equipment from reagent contamination, extend the service life of the equipment and reduce cleaning work. BRIEF DESCRIPTION OF THE DRAWINGS
