Description

Technical Field

[0001] The utility model belongs to the field of experimental auxiliary equipment, in particular to a water bath auxiliary device for connecting pipes. Background Art

[0002] The tube strip is also called the eight-tube strip, which is a commonly used experimental consumable. When using it, the staff will use a pipette to inject the sample to be processed into the tube strip for storage, so as to carry out subsequent analysis and processing of the sample.

[0003] When the analysis and processing of samples requires water bath heating, the staff will place the junction tubes containing the samples into the water bath. However, due to the small overall volume of the junction tubes and the lack of dedicated support and positioning components for the junction tubes in the existing water bath, the junction tubes are easily tipped over inside the water bath during water bath heating. The tipped junction tubes will not only increase the difficulty for the staff to remove them, but will also cause the samples inside the junction tubes to be unable to be fully immersed below the water surface, especially when multiple groups of junction tubes are heated in a water bath at one time, and there are differences in the volume of the samples in each group of junction tubes, it is difficult for the staff to reasonably control the depth of each group of junction tubes inserted into the water, which affects the heating effect of the samples and further affects the accuracy of the results of subsequent analysis and processing.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0030] A water bath auxiliary device for connecting pipes, the structure of which can be Figure 1-Figure 6 In this embodiment, the water bath auxiliary device for the connecting pipes includes a floating component and a fixing component, wherein the floating component is used to provide buoyancy for the connecting pipes 6 and limit the insertion posture of the connecting pipes 6 into the liquid surface, and the fixing component is detachably arranged on the floating component, and the connecting pipes 6 can be fixed by the fixing component, so that the staff can put the connecting pipes 6 into or take out the floating component conveniently, and flexibly adjust the insertion depth of the connecting pipes 6 into the liquid surface.

[0031] Specifically, Figure 5 As shown, the floating assembly includes: a floating frame, a first positioning plate 2 and a second positioning plate 3, wherein the first positioning plate 2 is arranged on the top of the floating frame, the second positioning plate 3 is arranged on the bottom of the floating frame, and an immersion channel 11 is arranged on the floating frame. In order to facilitate the liquid in the water bath to enter the immersion channel 11 and facilitate the contact between the strip pipes 6 to be treated and the liquid in the water bath, a plurality of first positioning hole groups are arranged on the first positioning plate 2, each of which includes two first positioning cutouts 21, each of which is connected to the immersion channel 11, and the two first positioning cutouts 21 in the same first positioning hole group are parallel to each other. A plurality of second positioning hole groups are arranged on the second positioning plate 3, each of which includes two second positioning cutouts 31, each of which is connected to the immersion channel 11, and the two second positioning cutouts 31 in the same second positioning hole group are parallel to each other.

[0032] It should be noted that, in order to ensure that the floating frame in the floating assembly has good buoyancy, the floating frame can be made of foam plastic. Accordingly, the staff can also choose other materials with good buoyancy in the prior art to make the floating frame to meet the actual use requirements of the device.

[0033] Optionally, in order to reduce the difficulty of assembling the first positioning plate 2 and the second positioning plate 3 with the floating frame, a first splicing pin 23 may be provided on the bottom surface of the first positioning plate 2, and a second splicing pin 33 may be provided on the top surface of the second positioning plate 3. Accordingly, a first splicing hole 13 for accommodating the first splicing pin 23 is provided on the top surface of the floating frame, and a second splicing hole for accommodating the second splicing pin 33 is provided on the bottom surface of the floating frame. During assembly, the staff may first apply adhesive to the splicing pins, and then insert the splicing pins into the corresponding splicing holes, so as to reliably fix the first positioning plate 2 and the second positioning plate 3 on the floating frame.

[0034] Figure 6 This is a schematic diagram of the fixing assembly in this embodiment. As shown in the figure, the fixing assembly includes a fixing plate 4 and an adjusting rod 5, wherein both ends of the fixing plate 4 are provided with fixing seats 41, each fixing seat 41 includes two fixing clips 42 for fixing the connecting pipe 6, and the two fixing clips 42 of the same fixing seat 41 are respectively located on both sides of the fixing plate 4. A threaded column 51 is provided at the bottom end of the adjusting rod 5, and a threaded hole 43 is also provided on the fixing plate 4. During assembly, the staff can place the threaded column 51 inside the threaded hole 43, and the bottom end of the threaded column 51 is pressed against the floating assembly, so as to flexibly adjust the insertion depth of the connecting pipe 6.

[0035] When in use, the staff can first place the floating assembly in the water bath, and the floating frame can make the floating assembly float on the water surface to facilitate carrying the row pipe 6. Since the first positioning plate 2 and the second positioning plate 3 are both provided with positioning cutouts, no matter whether the first positioning plate 2 or the second positioning plate 3 is facing upward, the positioning cutout facing downward can make the water in the water bath flow into the immersion channel 11. Subsequently, the staff can fix the tube body at both ends of the row pipe 6 through the fixing card 42, and insert the row pipe 6 into the immersion channel 11 along the positioning cutout facing upward through the fixing assembly, so that the row pipe 6 is in contact with the liquid in the water bath in a vertical posture. Compared with the traditional fixing method of the row pipe 6, since the number of fixing cards 42 in the present device is small, the overall weight of the fixing assembly can be significantly reduced, and the difficulty of assembling the row pipe 6 and the fixing assembly can be simplified, and the row pipe 6 can be prevented from tipping over in the water bath, thereby facilitating the staff to perform subsequent operations. In addition, since the bottom end of the threaded column 51 is against the floating assembly, the staff can also drive the adjusting rod 5 to rotate according to the sample volume in the coupling tube 6, so as to adjust the height of the fixing plate 4 with the help of the lifting effect of the threaded column 51, and then adjust the insertion depth of the coupling tube 6 to ensure that samples of different volumes are completely inserted below the liquid surface when being heated in a water bath.

[0036] Optionally, in order to prevent the fixing assembly from moving abnormally on the floating assembly, in this embodiment, a plurality of first limiting holes 22 for accommodating the threaded column 51 may be provided on the first positioning plate 2, and a plurality of second limiting holes 32 for accommodating the threaded column 51 may be provided on the second positioning plate 3. When assembling the fixing assembly and the floating assembly, the limiting holes can provide an accommodating space for the threaded column 51, and can limit the position of the threaded column 51 after the threaded column 51 is inserted into the limiting holes, thereby preventing the fixing assembly from moving abnormally on the floating assembly and ensuring that the connecting pipe 6 can be smoothly inserted into the positioning cutout.

[0037] As an optional implementation of this embodiment, in order to facilitate the staff to drive the adjusting rod 5 to rotate, an operating column 53 may be further provided at the top of the adjusting rod 5, and an anti-slip stripe is provided on the outer side wall of the operating column 53. When it is necessary to adjust the insertion depth of the coupling pipe 6, the staff can apply a rotation torque to the adjusting rod 5 through the operating column 53, thereby reducing the difficulty of rotating the adjusting rod 5.

[0038] In the actual working process, in order to improve the water bath heating efficiency of the sample, the staff usually water bathes multiple groups of row tubes 6 at one time. However, as the number of row tubes 6 changes, the buoyancy required to support the row tubes 6 floating on the water surface will also change. In order to meet the buoyancy requirements of different numbers of row tubes 6, the floating frame in this embodiment may include a plurality of floating bars 12 connected end to end, and a soaking channel 11 is formed by a plurality of floating bars 12, and the cross-section of each floating bar 12 is a trapezoid, and the small end of the trapezoid faces the first positioning plate 2, and the large end of the trapezoid faces the second positioning plate 3. At the same time, the number of the first positioning hole group on the first positioning plate 2 should also be greater than the number of the second positioning hole group on the second positioning plate 3.

[0039] Figure 1 and Figure 2 is a schematic diagram of the device in a state of use, such as Figure 1 and Figure 2 As shown, the first positioning plate 2 is facing upwards. In this state, since the first positioning plate 2 has a plurality of first positioning cutouts 21, a large number of row pipes 6 can be accommodated. At the same time, in this state, the large end of the trapezoidal cross section of the floating bar 12 faces downwards, so when the sinking stroke of the floating assembly remains constant, the buoyancy generated by the floating frame is greater, so that the device can have a higher load-bearing capacity and prevent the row pipes 6 from completely sinking to the bottom of the water.

[0040] Figure 3 and Figure 4 is a schematic diagram of the device in another use state, such as Figure 3 and Figure 4As shown, the second positioning plate 3 is facing upwards at this time. In this state, since the number of the second positioning cutouts 31 on the second positioning plate 3 is small, it is suitable for the centralized water bath treatment of a small number of connecting tubes 6. In this state, the small end of the trapezoidal cross section of the floating bar 12 faces downwards, so when the sinking stroke of the floating component remains constant, the buoyancy generated by the floating frame is smaller, so that the device can avoid the connecting tube 6 being unable to be inserted below the liquid surface due to excessive buoyancy, thereby ensuring that the sample in the connecting tube 6 obtains a good water bath heating effect.

[0041] As another optional implementation of this embodiment, in order to enhance the floating effect of the device in the water bath, a first weight-reducing cavity 24 may be provided inside the first positioning plate 2, a second weight-reducing cavity 34 may be provided inside the second positioning plate 3, and a third weight-reducing cavity 52 may be provided inside the adjusting rod 5. Thus, the overall weight of the device can be reduced by means of the first weight-reducing cavity 24, the second weight-reducing cavity 34 and the third weight-reducing cavity 52, thereby ensuring that the device can float in the water bath after carrying the row of tubes 6.

[0042] The effects of the above scheme are described below:

[0043] This embodiment provides a water bath auxiliary device for the row tubes, which can fix the row tubes through a fixing assembly, reducing the difficulty of placing and removing the row tubes from the water bath. At the same time, the device can guide and limit the row tubes through the positioning cutouts to ensure that the row tubes are inserted into the water in a vertical posture. In addition, the device can also adjust the height of the fixing plate with the help of an adjusting rod, and then adjust the depth of the row tubes inserted into the water to adapt to the heating of samples of different volumes. In addition, the device can also select the use state according to the number of row tubes to be processed, and provide different buoyancy according to different use states, so as to meet a variety of use requirements.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
