Description

Technical Field

[0001] The invention relates to a test tube shaking device, in particular to a multi-tube parallel high-safety test tube shaking device applied in the field of shaking devices. Background Art

[0002] A test tube shaker is a device used to mix and shake liquids or solutions in test tubes. It mainly rotates or vibrates the test tube mechanically to promote the mixing and dissolution of liquids. It is widely used in biochemistry, molecular biology, medical experiments and other fields. It can quickly and evenly mix the liquid in the test tube and improve the efficiency of the experiment.

[0003] The specification of invention patent CN201611165709.2 discloses a test tube shaking device, which realizes the function of shaking the test tube horizontally or vertically through horizontal and vertical tracks and sliding columns, realizing the diversity of experiments. The cooperation of fixed magnets and adsorption magnets realizes the blocking effect of the reversing plate on the longitudinal track and the horizontal track. The thickness of the adsorption magnets and the fixed magnets is equal to the thickness of the vertical plate, ensuring the smoothness of the test tube clamp in the horizontal track or the longitudinal track. The cooperation of the connecting column and the connecting ring on the test tube clamp realizes the detachability of the test tube; the baffle on the test tube clamp ensures the longitudinal stability of the test tube clamp.

[0004] In the prior art, magnets are used to achieve the smoothness and stability of the movement of the test tube clamp. However, the above patent is only applicable to the shaking of a single test tube, and the test tube needs to be tightly closed during the shaking process. The shaking efficiency is low, the scope of application is small, and it is difficult to promote it on a large scale. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that in the prior art, the test tube needs to be tightly closed during the shaking process, the shaking efficiency is low, the application scope is small, and it is difficult to promote it on a large scale.

[0006] In order to solve the above problems, the present invention provides a high-safety test tube shaking device for multiple tubes in parallel, comprising a frame, the frame comprising a base, a vertical plate fixedly connected to the upper end of the base, a counterweight block inlaid on the base, a workbench fixedly connected to the side wall of the vertical plate, a motor fixedly connected to the tool table, a power output end of the motor passes through the vertical plate and extends to the other side of the motor, a driven shaft rotatably connected to the vertical plate and matched with the power output end of the motor, the driven shaft passes through the vertical plate, a pair of power arms are arranged on one side of the vertical plate, the two power arms are respectively fixedly connected to the power output end of the motor and the driven shaft, a power plate is fixedly connected between the two power arms, a shaking frame is arranged on the side of the power plate away from the power arm, a plurality of fixing columns are fixedly connected between the power plate and the shaking frame, a plurality of mounting holes are drilled on the upper end of the shaking frame, and standard bottles and a plurality of test tubes matching the shaking frame are respectively inserted into the plurality of mounting holes;

[0007] The standard bottle includes a bottle body, a sealing plug matching the bottle body is fixedly connected to the opening of the bottle body, an outer shell matching the bottle body is slidably connected inside the bottle body, an electric telescopic rod is fixedly connected between the sealing plug and the outer shell, a gravity sensor is inserted in the outer shell, and the outer shell is fixedly connected to the gravity sensor.

[0008] In the above-mentioned high-safety test tube shaking device with multiple tubes in parallel, liquid water in the test tubes is not easy to splash, thereby increasing the safety of the shaking device.

[0009] As a further improvement of the present application, the length of the electric telescopic rod can be automatically adjusted, and the more dangerous the solvent filled in the test tube, the longer the electric telescopic rod can be, so that the detection sensitivity of the standard bottle can be adjusted to reduce the risk of solvent splashing in the test tube.

[0010] As a further improvement of the present application, the outer wall of the shell is coated with a hydrophilic solvent, and the lower end of the shell is frosted, so that liquid water can easily adhere to the shell for a long time, thereby increasing the accuracy of gravity sensor detection.

[0011] As a further improvement of the present application, a buffer pad is fixedly connected to the lower inner wall of the shaking rack, and the buffer pad includes an elastic bag filled with a buffer solution, which increases the protection of the test tube and the standard bottle and reduces the hard contact between the test tube and the standard bottle.

[0012] As a further improvement and supplement to the present application, a plurality of impact balls are filled in the elastic bag, and the plurality of impact balls are suspended in a buffer solution. The impact balls will rotate on the shaking rack and move together. During the rotation, the impact balls will impact the test tube, thereby increasing the shaking effect of the test tube.

[0013] As another improvement of the present application, the test tube includes a storage portion and a limiting portion, and the limiting portion is located at the upper end of the storage portion, a splash-proof unit is slidably connected inside the storage portion, and the density of the splash-proof unit is less than that of liquid water, the diameter of the disk-shaped portion at the center of the splash-proof unit is smaller than the inner diameter of the limiting portion, and a plurality of radial portions are fixedly connected to the outer wall of the disk-shaped portion. When the solvent is injected into the test tube, the splash-proof unit will float on the surface of the solvent, which can effectively prevent the solvent filled in the test tube from splashing.

[0014] As another improvement supplement to the present application, the side cross-section of the disk-shaped portion of the splash-proof unit is in the shape of a bamboo hat, that is, the disk-shaped portion of the splash-proof unit is high in the middle and low on both sides, so that a small amount of splashed solvent can easily roll off the splash-proof unit back into the storage portion.

[0015] As another improved supplement of the present application, the upper end of the splash-proof unit is coated with a hydrophobic coating, and the upper end of the splash-proof unit has a smooth surface, so that it is not easy for solvent to remain on the surface of the splash-proof unit.

[0016] In summary, in the present application, on the one hand, the shaking amplitude of the solvent is detected as multiple during the shaking process. As the shaking degree of the standard bottle increases, the liquid water filled in the bottle body will also shake until the liquid water adheres to the gravity sensor, causing the data detected by the outer shell to change, that is, there is liquid water attached to the gravity sensor. At this time, there is a risk of splashing of the liquid water in the standard bottle. The rotation speed of the motor is fixed and no longer increases, so that the liquid water in the test tube is not easy to splash, thereby increasing the safety of using the shaking device.

[0017] At the same time, an anti-splash unit is added to further protect the solvent in the storage part. Even if the motor speed is too high, it is not easy to cause a large amount of solvent splashing, thereby increasing the safety of the test tube shaking device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0031] The first implementation method:

[0032] Figure 1-3 A high-safety test tube shaking device with multiple tubes in parallel is shown, comprising a frame 1, the frame 1 comprising a base 101, a vertical plate 102 is fixedly connected to the upper end of the base 101, a counterweight block 103 is inlaid on the base 101, a workbench is fixedly connected to the side wall of the vertical plate 102, a motor 2 is fixedly connected to the tool bench, a power output end of the motor 2 passes through the vertical plate 102 and extends to the other side of the motor 2, a driven shaft 4 whose position matches the power output end of the motor 2 is rotatably connected to the vertical plate 102, the driven shaft 4 passes through the vertical plate 102, a pair of power arms 3 are provided on one side of the vertical plate 102, the two power arms 3 are fixedly connected to the power output end of the motor 2 and the driven shaft 4, a power plate 5 is fixedly connected between the two power arms 3, a shaking frame 7 is provided on the side of the power plate 5 away from the power arm 3, a plurality of fixed columns 6 are fixedly connected between the power plate 5 and the shaking frame 7, a plurality of mounting holes are drilled on the upper end of the shaking frame 7, standard bottles 9 and a plurality of test tubes 8 matching themselves are respectively inserted into the plurality of mounting holes;

[0033] See also Figure 4-7 The standard bottle 9 includes a bottle body 901, a sealing plug 902 matching the bottle body 901 is fixedly connected to the opening of the bottle body 901, a shell 904 matching the bottle body 901 is slidably connected inside the bottle body 901, an electric telescopic rod 903 is fixedly connected between the sealing plug 902 and the shell 904, a gravity sensor 905 is inserted into the shell 904, and the shell 904 is fixedly connected to the gravity sensor 905.

[0034] In the present application, a shaking rack 7 is used to shake multiple test tubes 8 together. During the shaking process, a standard bottle 9 is used as a standard part. Before the shaking work starts, the same amount of liquid water as that of multiple test tubes 8 is injected into the standard bottle 9. When the amount of solvent in the multiple test tubes 8 is different, the liquid water filled in the standard bottle 9 is based on the test tube with the largest number of test tubes 8. Then, the multiple test tubes 8 and the standard bottle 9 are installed on the shaking rack 7 together. During the operation of the shaking machine, the rotation speed of the motor 2 will gradually increase from low to high, thereby driving the speed of the power arm 3 to gradually increase, that is, the rotation speed of the shaking rack 7 will also gradually increase, and the test tubes 8 and the standard bottle 9 will be shaken more thoroughly.

[0035] As the shaking degree of the standard bottle 9 increases, the liquid water filled in the bottle body 901 will also shake until the liquid water adheres to the gravity sensor 905, causing the data detected by the shell 904 to change, that is, there is liquid water adhering to the gravity sensor 905. At this time, there is a risk of splashing of the liquid water in the standard bottle 9, and the rotation speed of the motor 2 is fixed and no longer increases, so that the liquid water in the test tube 8 is not easy to splash, thereby increasing the safety of using the shaking device.

[0036] The length of the electric telescopic rod 903 can be automatically adjusted, and the more dangerous the solvent filled in the test tube 8 is, the longer the electric telescopic rod 903 is. The detection sensitivity of the standard bottle 9 can be adjusted to reduce the risk of splashing of the solvent in the test tube 8. The outer wall of the shell 904 is coated with a hydrophilic solvent, and the lower end of the shell 904 is frosted, so that liquid water can easily adhere to the shell 904 for a long time, thereby increasing the accuracy of detection by the gravity sensor 905.

[0037] See also Figure 3-4 A buffer pad 10 is fixedly connected to the lower inner wall of the shaking frame 7, and the buffer pad 10 includes an elastic bag 1001. The elastic bag 1001 is filled with a buffer solution to increase the protection of the test tube 8 and the standard bottle 9 and reduce the hard contact between the test tube 8 and the standard bottle 9. The elastic bag 1001 is filled with a plurality of impact balls 1002, and the plurality of impact balls 1002 are suspended in the buffer solution. The impact balls 1002 will also move together with the rotation of the shaking frame 7. During the rotation, the impact balls 1002 will impact the test tube 8, thereby increasing the shaking effect of the test tube 8.

[0038] The second implementation method:

[0039] Figure 8-10In the test tube 8 shown, the test tube 8 includes a storage part 801 and a limiting part 802, and the limiting part 802 is located at the upper end of the storage part 801, and a splash-proof unit 803 is slidably connected inside the storage part 801, and the density of the splash-proof unit 803 is less than that of liquid water, and the diameter of the disk-shaped part at the center of the splash-proof unit 803 is smaller than the inner diameter of the limiting part 802, and a plurality of radial parts are fixedly connected to the outer wall of the disk-shaped part. When the solvent is injected into the test tube 8, the splash-proof unit 803 will float on the surface of the solvent, which can effectively prevent the solvent filled in the test tube 8 from splashing.

[0040] The side cross-section of the disk-shaped portion of the splash-proof unit 803 is in the shape of a conical hat, that is, the disk-shaped portion of the splash-proof unit 803 is higher in the middle and lower on both sides. A small amount of splashed solvent can easily roll back from the splash-proof unit 803 into the storage unit 801. The upper end of the splash-proof unit 803 is coated with a hydrophobic coating, and the upper end of the splash-proof unit 803 has a smooth surface, so that it is not easy for solvent to remain on the surface of the splash-proof unit 803.

[0041] Compared with the first embodiment, in this embodiment, the test tube 8 is further designed and a splash-proof unit 803 is added to further protect the solvent in the storage part 801. Even if the speed of the motor 2 is too high, it is not easy to cause a large amount of solvent splashing, thereby increasing the safety of the test tube shaking device.

[0042] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
