[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0033] Depend on Figure 1 to Figure 2 Provided is a colorimetric tube digestion rack, comprising a bottom plate 1, a plurality of colorimetric tube bases 11, a plurality of elastic lifting mechanisms, a column 2, a middle plate 3, a plurality of colorimetric tube fixing holes 31, a clamping mechanism, a panel 4, a plurality of tube cover holes 41, a plurality of exhaust holes 42, a plurality of exhaust ports 43 and a plate cover mechanism.
[0034] First of all, the base plate 1 is a circular structure, and three rubber bases 12 are installed in a circular array at the bottom of the base plate 1. The three rubber bases 12 are triangular structures to increase stability; multiple colorimetric tube bases 11 are opened on the top of the base plate 1, and the multiple colorimetric tube bases 11 are cylindrical structures. The bottom of the colorimetric tube is inserted into the colorimetric tube base 11, and the colorimetric tube base 11 fixes the bottom of the colorimetric tube.
[0035] Depend on Figures 2 to 3 It is given that multiple elastic lifting mechanisms are respectively installed at the bottom of multiple colorimetric tube bases 11. The following is a detailed description of the installation structure of an elastic lifting mechanism. The elastic lifting mechanism includes a spring 5 and a support plate 51. The spring 5 is installed at the bottom of the colorimetric tube base 11. The support plate 51 is slidably installed inside the colorimetric tube base 11. The bottom of the support plate 51 is installed on the top of the spring 5. The spring 5 will push the support plate 51 upward, and the top of the support plate 51 supports the bottom of the colorimetric tube, providing elastic support for the colorimetric tube, which can play a buffering role.
[0036] Depend on Figure 1 to Figure 2 It is given, and secondly, it is explained that four columns 2 are provided, and the four columns 2 are installed in a circular array on the top of the base plate 1, and the middle plate 3 is installed in the middle of the four columns 2. A plurality of colorimetric tube fixing holes 31 are opened through the top of the middle plate 3. Specifically, the colorimetric tube is inserted into the colorimetric tube fixing hole 31, and the colorimetric tube fixing hole 31 fixes the middle of the colorimetric tube.
[0037] Depend on Figure 4 and Figure 5 It is given and further explained that a plurality of clamping mechanisms are respectively installed in a plurality of colorimetric tube fixing holes 31 . The following is a detailed description of a clamping mechanism, which includes a fixing ring 6 , a plurality of elastic blocks 61 , a clamp 62 , a positioning ring slot 63 and a positioning block 64 .
[0038] Specifically, the fixing ring 6 is installed inside the colorimetric tube fixing hole 31, and a plurality of elastic blocks 61 are arranged around the inner wall of the fixing ring 6. It should be noted that the elastic blocks 61 are made of elastic materials such as rubber and silicone. When the colorimetric tube is inserted into the fixing ring 6, the colorimetric tube is deformed against the elastic blocks 61 during insertion, and then the elastic blocks 61 clamp and limit the outer wall of the colorimetric tube around to prevent the colorimetric tube from shaking.
[0039] More specifically, the clamp 62 is threadedly installed on the inner top end of the colorimetric tube fixing hole 31, the positioning ring groove 63 is opened at the top of the fixing ring 6, and the positioning block 64 is arranged at the bottom of the clamp 62, and the positioning block 64 is clamped in the positioning ring groove 63; as described in the function, the clamp 62 squeezes and fixes the fixing ring 6 to facilitate the installation of the fixing ring 6 in the colorimetric tube fixing hole 31, and the positioning block 64 cooperates with the positioning ring groove 63 to prevent the fixing ring 6 from being separated from the colorimetric tube fixing hole 31 when the fixing ring 6 is squeezed by the colorimetric tube.
[0040] Depend on Figure 2 and Figure 6 Finally, it is explained that the panel 4 is clamped on the top of the four columns 2. Specifically, four column fixing holes 44 are opened at the bottom of the panel 4, and the top of the column 2 is provided with an elliptical ball block 21. The four elliptical ball blocks 21 are respectively inserted and installed in the four column fixing holes 44, and the middle of the inner wall of the four column fixing holes 44 is provided with a rubber clamp 45 that matches the four elliptical ball blocks 21; installation instructions, the column fixing holes 44 are aligned with the elliptical ball blocks 21 set on the top of the four columns 2, and the panel 4 is pressed to make the elliptical ball blocks 21 inserted into the column fixing holes 44. When the elliptical ball block 21 abuts against the rubber clamp 45, the rubber clamp 45 is deformed by the extrusion force until the elliptical ball block 21 is completely inserted into the column fixing hole 44, and the rubber clamp 45 rebounds and resets, and the rubber clamp 45 limits the bottom of the elliptical ball block 21.
[0041] Specifically, the elliptical ball block 21 and the rubber clamp ring 45 are interference fit.
[0042] It is also explained that a plurality of tube cover holes 41 are opened at the bottom of the panel 4, and a plurality of exhaust holes 42 are opened at the top of the panel 4. The exhaust holes 42 are vertically arranged with the tube cover holes 41, and the exhaust holes 42 are communicated with the tube cover holes 41. The tube cover part of the colorimetric tube is inserted into the tube cover hole 41, and the tube cover hole 41 limits and fixes the top of the colorimetric tube.
[0043] To be more specific, and because the diameter of the exhaust hole 42 is smaller than the diameter of the tube cover hole 41, the inner edge of the exhaust hole 42 abuts against the top of the colorimetric tube to limit the top of the colorimetric tube; combined with the above description, when the heights of the colorimetric tubes are different, the spring 5 presses against the support plate 51, the support plate 51 supports the bottom of the colorimetric tube upward, and the inner edge of the exhaust hole 42 limits the colorimetric tube cover, thus ensuring that the colorimetric tube cover of any height will abut against the inner edge of the exhaust hole 42, ensuring that the colorimetric tube cover is always in a tightly closed state.
[0044] Mainly, multiple exhaust ports 43 are opened around the side wall of the panel 4, and the multiple exhaust ports 43 are respectively connected with the multiple exhaust holes 42, and one exhaust port 43 is only connected with one exhaust hole 42. Specifically, when the colorimetric tube is steam-heated, the gas generated by the colorimetric tube is discharged into the exhaust hole 42, and then enters the exhaust port 43 from the exhaust hole 42 for discharge; the exhaust hole 42 and the exhaust port 43 are connected separately to prevent the gas from contacting the colorimetric tube next to it during the exhaust process, causing cross contamination.
[0045] Depend on Figure 1 to Figure 2 It is also necessary to explain that the plate cover mechanism is rotatably mounted on the top of the panel 4, and the plate cover mechanism includes a shell cover 7, a hinge 71, a lock hook 72, a lock buckle 73 and a cotton rope 74.
[0046] Specifically, the shell cover 7 is rotatably installed on the top of the panel 4 through a hinge 71, the lock hook 72 is installed on the side of the shell cover 7 away from the hinge 71, the lock buckle 73 is installed on the side of the panel 4 away from the hinge 71, the lock buckle 73 is hooked on the lock hook 72, and the cotton rope 74 is arranged on the top of the shell cover 7. The cotton rope 74 makes it easy to take out the colorimetric tube digestion rack from the pressure cooker at a higher temperature.
[0047] Additional explanation: the bottom of the colorimetric tube is fixed by the colorimetric tube base 11, the middle of the colorimetric tube is fixed by the colorimetric tube fixing hole 31, and the top of the colorimetric tube is fixed by the tube cover hole 41. There is a distance between each colorimetric tube, which is convenient for steam heating so that the colorimetric tubes are heated evenly when heated.
[0048] The beneficial effects obtained by the bottom plate 1, multiple colorimetric tube bases 11, multiple elastic jacking mechanisms, columns 2, middle plate 3, multiple colorimetric tube fixing holes 31, clamping mechanisms, panels 4, multiple tube cover holes 41, multiple exhaust holes 42, multiple exhaust ports 43 and plate cover mechanisms are as follows: the utility model forms a digestion rack through the bottom plate 1, columns 2, middle plate 3 and panel 4, the colorimetric tubes are placed in the digestion rack, the colorimetric tube bases 11 arranged on the bottom plate 1 are used to fix the bottom of the colorimetric tube, and the colorimetric tube fixing holes 31 arranged on the middle plate 3 are used to fix the middle of the colorimetric tube. At the same time, the spring 5 and the top plate 51 elastically support the bottom of the colorimetric tube, so that the panel 4 presses the colorimetric tube cover to prevent the gas generated during the digestion process from rushing open the colorimetric tube cover, and there is no need to bind the colorimetric tube and the cover, which saves work efficiency, reduces detection time, and saves time and effort.
[0049] The utility model can avoid cross contamination of gas generated by heating the sample by independently communicating the exhaust hole 42 with the exhaust port 43 .
[0050] When the utility model is used, a proper amount of sample is taken and placed in a 50mL colorimetric tube, 4mL of a 50g / L potassium persulfate solution is added, and the colorimetric tube cover is covered and a sample label is affixed;
[0051] During heating, the colorimetric tube is inserted from the colorimetric tube fixing hole 31, and the bottom of the colorimetric tube is inserted into the colorimetric tube base 11. Then the panel 4 is installed on the top of the column 2, and the top of the colorimetric tube is inserted into the tube cover hole 41. The colorimetric tube digestion rack is placed in a high-pressure steam pressure cooker and digested at 120°C and 1.1kg / cm3 pressure;
[0052] After the digestion is completed, the cotton rope 74 is extracted and the colorimetric tube digestion rack is taken out from the high pressure steam pressure cooker to complete the digestion process.
[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
