Description

Technical Field

[0001] The utility model belongs to the technical field of test tube clamps, in particular to a test tube clamp adapted for a rotary mixer. Background Art

[0002] A rotary mixer is a device that achieves liquid mixing through rotational motion. It is widely used in experiments in biology, chemistry, medicine and other fields. It has the advantages of improving mixing efficiency, maintaining sample uniformity, and reducing experimental errors. It is an indispensable and important equipment in the laboratory.

[0003] When installing test tubes on a rotary mixer, a test tube clamp is usually required to ensure the stability and safety of the test tubes. The single-layer silicone test tube clamp commonly used in existing rotary mixers can adapt to test tubes of different sizes to a certain extent. However, due to the limitations of its single-layer design, the test tubes often lack sufficient stability during the rotary mixing process. This single-layer fixing method easily causes the test tubes to shake when rotating at high speed, which not only affects the mixing effect, but may also cause the test tubes to fall off due to unstable placement, thereby interfering with the experiment and even damaging the test tubes and samples. Therefore, it needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems. The utility model provides a test tube clamp adapted for a rotary mixer, which has the advantages of not being easy to fall off and having good stability.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a test tube clamp adapted for a rotary mixer, comprising a fixed plate, wherein the left and right sides of the fixed plate are bolted to a rotating shaft, the interior of the fixed plate is movably sleeved with a clamp body, an upper soft edge is fixedly installed on the top of the inner surface of the clamp body, a lower soft edge is fixedly installed on the bottom of the inner surface of the clamp body, a slot is provided in the middle of the outer surface of the fixed plate, and the outer surface of the slot is movably sleeved with the inner surface of the fixed plate.

[0006] As a preferred embodiment of the present invention, the upper soft edge and the lower soft edge have the same appearance, and the upper soft edge and the lower soft edge are staggered with each other in the vertical direction.

[0007] As a preferred embodiment of the present invention, the clamp body, the upper soft edge and the lower soft edge are all made of silicone, and the inner diameter of the card slot is the same as the inner diameter of the hole inside the fixing plate.

[0008] As a preferred embodiment of the present invention, the inner sides of the upper soft edge and the lower soft edge are both arc-shaped, and the inner diameters of the upper soft edge and the lower soft edge are the same.

[0009] As a preferred embodiment of the present invention, the upper soft edge and the lower soft edge have different specifications according to different test tube diameters, and the inner diameters of the upper soft edge and the lower soft edge are both smaller than the corresponding test tube diameters.

[0010] As a preferred embodiment of the present invention, the top of the upper soft edge and the top of the clamp body are in the same plane, and the bottom of the lower soft edge and the bottom of the clamp body are in the same plane.

[0011] As a preferred embodiment of the present invention, the inner diameter of the clamp body is larger than the diameter of the test tube, and the inner surface of the clamp body is smooth.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The utility model provides a clamp body, an upper soft edge and a lower soft edge. Due to the design of the upper soft edge and the lower soft edge, the test tube can be double-fixed, so that the test tube can be fixed more stably, and the test tube is prevented from falling off during the rotation process. Since the test tube is fixed by the upper soft edge and the lower soft edge at the same time, the test tube can be perpendicular to the fixing plate, and the test tube is prevented from tilting after being placed. Moreover, since the clamp body as a whole has different models, it can be adapted to test tubes of different capacities. The upper soft edge and the lower soft edge are made of silicone, which can ensure that sufficient friction is generated when in contact with the test tube, and effectively prevent the test tube from falling off or loosening during the rotation and mixing process.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1 to 6 As shown, the utility model provides a test tube clamp adapted for a rotary mixer, comprising a fixed plate 1, a rotating shaft 2 being bolted to the left and right sides of the fixed plate 1, a clamp body 3 being movably sleeved inside the fixed plate 1, an upper soft edge 4 being fixedly mounted on the top of the inner surface of the clamp body 3, a lower soft edge 5 being fixedly mounted on the bottom of the inner surface of the clamp body 3, a slot 6 being opened in the middle of the outer surface of the fixed plate 1, and the outer surface of the slot 6 being movably sleeved with the inner surface of the fixed plate 1; as shown in the attached manual Figure 6 As shown, from left to right are test tubes corresponding to 5ml, 15ml and 50ml respectively. The operator installs the corresponding clamp body 3 inside the fixed plate 1 according to the size of the hole inside the fixed plate 1, so as to facilitate the operator to place test tubes of different capacities. Due to the design of the upper soft edge 4 and the lower soft edge 5, the test tube can be fixed more stably, and because the test tube is fixed by the upper soft edge 4 and the lower soft edge 5 at the same time, the test tube can be perpendicular to the fixed plate 1, avoiding the occurrence of skew after the test tube is placed. The number of upper soft edges 4 and lower soft edges 5 inside each clamp body 3 can be three, four, five, six or other different numbers, and the operator can select according to needs.

[0023] Among them, the upper soft edge 4 and the lower soft edge 5 have the same appearance, and the upper soft edge 4 and the lower soft edge 5 are staggered with each other in the vertical direction; since the upper soft edge 4 and the lower soft edge 5 are staggered with each other in the vertical direction, the test tube can be fixed more comprehensively, so that the test tube can be placed more stably inside the clamp body 3.

[0024] Among them, the clamp body 3, the upper soft edge 4 and the lower soft edge 5 are all made of silicone, and the inner diameter of the slot 6 is the same as the inner diameter of the hole inside the fixed plate 1; by selecting silicone material, the upper soft edge 4 and the lower soft edge 5 have good elasticity and wear resistance, which can ensure sufficient friction when in contact with the test tube, effectively preventing the test tube from slipping or loosening during the rotation and mixing process. At the same time, the soft properties of silicone can also avoid scratches or damage to the test tube, ensuring the integrity of the test tube and the safety of the experiment.

[0025] Among them, the inner sides of the upper soft edge 4 and the lower soft edge 5 are both arc-shaped, and the inner diameters of the upper soft edge 4 and the lower soft edge 5 are the same; since the inner sides of the upper soft edge 4 and the lower soft edge 5 are both arc-shaped, the upper soft edge 4 and the lower soft edge 5 can fix the test tube more closely and adapt to the contour of the test tube, providing a larger contact area, thereby increasing the stability and firmness of the fixation.

[0026] Among them, the upper soft edge 4 and the lower soft edge 5 have different specifications according to the different test tube diameters, and the inner diameters of the upper soft edge 4 and the lower soft edge 5 are both smaller than the diameter of the adapted test tube; since the upper soft edge 4 and the lower soft edge 5 have different specifications, the operator can select a suitable clamp body 3 for installation according to the diameter of the test tube used, thereby ensuring that the test tube can be firmly fixed in the clamp. At the same time, since the inner diameters of the upper soft edge 4 and the lower soft edge 5 are both smaller than the diameter of the adapted test tube, the test tube can be tightly clamped by the upper soft edge 4 and the lower soft edge 5 when inserted into the interior of the clamp body 3, effectively preventing the test tube from shaking or slipping during the rotation and mixing process.

[0027] Among them, the top of the upper soft edge 4 is in the same plane as the top of the clamp body 3, and the bottom of the lower soft edge 5 is in the same plane as the bottom of the clamp body 3; this design can keep the upper soft edge 4 and the lower soft edge 5 at a distance, so that the test tube can be fixed from the top and bottom at the same time, improving the fixing effect of the test tube while ensuring that the test tube can be perpendicular to the fixing plate 1.

[0028] Among them, the inner diameter of the clamp body 3 is larger than the diameter of the test tube, and the inner surface of the clamp body 3 is smooth; this design can make it easier to insert the test tube into the interior of the clamp body 3, avoiding the need for the operator to calibrate when inserting the test tube.

[0029] The working principle and use process of this utility model:

[0030] The operator connects the fixed plate 1 to the rotating shaft 2 inside the mixer with bolts, and then installs the corresponding model of the clamp body 3 inside the fixed plate 1 according to the size of the hole inside the fixed plate 1, so that the slot 6 is engaged with the edge of the hole inside the fixed plate 1, and then inserts the test tube into the corresponding clamp body 3 to complete the fixation of the test tube. Finally, by starting the rotary mixer, the rotating shaft 2 drives the fixed plate 1 to rotate, thereby causing the test tube to rotate, and then the liquid inside the test tube can be mixed. When the test tube is inserted into the inside of the clamp body 3, the upper soft edge 4 and the lower soft edge 5 will fix the test tube to ensure the stability of the test tube during rotation and prevent the test tube from falling off. At the same time, the test tube can be perpendicular to the fixed plate 1 to prevent the test tube from being skewed.
