Description

Technical Field

[0001] The utility model belongs to the technical field of test tube experiments, in particular to a combined test tube rack. Background Art

[0002] A test tube is a common laboratory equipment, mainly used to hold liquid or solid reagents, heat small amounts of solids or liquids, prepare or collect small amounts of gas reactions, dissolve small amounts of gas, liquid or solid solutes, and as a container during centrifugation.

[0003] During use, test tubes are usually placed on test tube racks for experiments, such as colorimetric tests and dropper tests. Test tubes are also generally stored in test tube racks.

[0004] However, in the process of using the test tube rack, it is often encountered that the existing test tube rack is difficult to adjust due to its poor expansibility, or the test tube is not placed properly. In the colorimetric test, the background is messy, it is not easy to compare the color, or the partition in the middle of the test tube rack just blocks the colorimetric liquid level. At the same time, when encountering a large number of test tubes, since the test tubes are difficult to expand, multiple test tube racks are used for comparison, but there is a problem of difference in liquid level, etc., which makes it difficult to judge the results. Summary of the invention

[0005] The utility model aims to provide a combined test tube rack to solve the problem of poor expansibility of the existing test tube racks in view of the problems existing in the prior art.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a combined test tube rack, including a tube plate and side frame plates arranged on both sides of the tube plate, the side frame plates include side panels and longitudinal splicing strips arranged on the front of the side panels, the back of the side panels are provided with longitudinal splicing grooves adapted to the longitudinal splicing strips, both sides of the side panels are vertically equidistantly provided with a plurality of transverse splicing grooves adapted to the tube plate, and colorimetric grooves are provided on both sides of the side panels and between the transverse splicing grooves and the longitudinal splicing grooves.

[0007] Through the above technical scheme, the insert tube plate can be inserted into the horizontal splicing grooves of different heights, so as to change the height of the test tube rack, so as to adapt to test tubes with different liquid level heights and avoid the insert tube plate blocking the colorimetric liquid surface. At the same time, multiple side frame plates and multiple insert tube plates can be used for horizontal splicing, so as to flexibly expand the test tube rack in the horizontal direction, so as to facilitate the experimenter to perform colorimetric tests on more test tubes. Multiple side frame plates can also be used for vertical splicing, so that the longitudinal splicing strip of one side frame plate is inserted into the longitudinal splicing groove of another side frame plate, so that more test tubes can be stored per unit area, which is convenient for storing test tubes and performing other test tube tests later. In summary, the present application greatly enhances the extensibility of the test tube rack compared with the existing test tube rack.

[0008] Optionally, the inserting plate includes a transverse plate and an inserting plate arranged in the middle of both ends of the transverse plate, and the inserting plate is adapted to the transverse splicing groove.

[0009] The plug-in plate is used to form a transverse splicing groove on the side wall of the plug-in plate and the side frame plate, so that the plug-in plate and the side frame plate can be quickly disassembled and installed.

[0010] Optionally, a rubber upper gasket is fixedly mounted on the upper surface of the plug plate, and the upper surface of the rubber upper gasket is an arc-shaped arch surface.

[0011] After the plug board is inserted into the transverse splicing groove, the rubber upper gasket is squeezed by the transverse splicing groove to make the plug board and the side frame board more tightly connected.

[0012] Optionally, a plurality of insertion holes are evenly opened on the transverse plate, and a reducing spring piece is fixedly installed on the inner wall of the insertion hole. The reducing spring piece is composed of a plurality of rubber petal spring pieces, and a gap is reserved between two adjacent rubber petal spring pieces.

[0013] The rubber petal spring can adapt to test tubes of different diameters and can also press and limit the test tubes.

[0014] Optionally, the transverse plates are provided in several groups, and the hole diameters of the jacks on the transverse plates in different groups are different.

[0015] For test tubes with large diameter differences, a cross plate with matching apertures can be reasonably selected.

[0016] Optionally, the heights of the longitudinal splicing strip and the longitudinal splicing groove are equal to the height of the side panels, and side gaskets are fixedly installed on both sides of the longitudinal splicing strip.

[0017] The use of longitudinal splicing strips and longitudinal splicing grooves with a height equal to that of the side panels can make it more convenient for testers to assemble and splice longitudinally. At the same time, the use of side gaskets can make the side panels tighter when spliced ​​longitudinally.

[0018] Optionally, the height of the colorimetric groove is equal to the height of the side panels, and a colorimetric plate is inserted between the two horizontal panels and located on the inner side of the colorimetric groove.

[0019] After the colorimetric plate is inserted into the colorimetric slot, it serves as the background for the test tubes and is used by the experimenter to perform colorimetric tests on the test tubes placed in a row.

[0020] Compared with the prior art, the beneficial effects of the utility model are: 1. The insert tube plate can be inserted into the horizontal splicing grooves of different heights, thereby changing the height of the test tube rack, so as to adapt to test tubes with different liquid level heights and avoid the insert tube plate blocking the colorimetric liquid surface. At the same time, multiple side frame plates and multiple insert tube plates can be used for horizontal splicing, so as to flexibly expand the test tube rack in the horizontal direction, so as to facilitate the experimenter to perform colorimetric tests on more test tubes. Multiple side frame plates can also be used for vertical splicing, so that the longitudinal splicing strip of one side frame plate is inserted into the longitudinal splicing groove of another side frame plate, thereby expanding the number of test tubes stored in the test tube rack, facilitating the storage of test tubes and performing other test tube tests later, thereby greatly improving the expansibility of the test tube rack; 2. Through horizontal plates with different hole diameters, test tubes of different diameters can be adapted; 3. Rubber petal springs installed on the inner wall of the hole can compress and limit the test tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution 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.

[0028] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "middle", "upper", "lower", "left", "right", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0029] like Figure 1 As shown, the specific scheme of the embodiment is as follows: a combined test tube rack includes an inserting tube plate 1 and side frame plates 2 arranged on both sides of the inserting tube plate 1.

[0030] like Figure 3 As shown, in this embodiment, the side frame plate 2 includes a side panel 21 and a longitudinal splicing strip 22 integrally formed on the front side of the side panel 21, a longitudinal splicing groove 23 adapted to the longitudinal splicing strip 22 is provided on the back side of the side panel 21, a plurality of transverse splicing grooves 25 adapted to the insertion tube plate 1 are vertically equidistantly provided on both sides of the side panel 21, and a colorimetric groove 26 is provided on both sides of the side panel 21 and between the transverse splicing grooves 25 and the longitudinal splicing grooves 23.

[0031] The insert plate 1 can be inserted into the transverse splicing grooves 25 of different heights, so as to change the height of the test tube rack to adapt to test tubes with different liquid level heights and avoid the insert plate 1 blocking the colorimetric liquid surface.

[0032] like Figure 3 As shown, in this embodiment, the height of the longitudinal splicing strip 22 and the longitudinal splicing groove 23 are equal to the height of the side panel 21, and side gaskets 24 are fixedly installed on both sides of the longitudinal splicing strip 22. The longitudinal splicing strip 22 and the longitudinal splicing groove 23 with the same height as the side panel 21 can make it more convenient for the tester to assemble and splice in the longitudinal direction, and the side gaskets 24 can also make the side panels 21 more compact when splicing in the longitudinal direction.

[0033] like Figure 3~4 As shown, it should be noted that the height of the colorimetric slot 26 is equal to the height of the side plate 21, and a colorimetric plate 3 is inserted between the two horizontal plates 11 and located inside the colorimetric slot 26. After the colorimetric plate 3 is inserted into the colorimetric slot 26, it serves as a background for the test tubes, and is used by the tester to perform a colorimetric test on the test tubes placed in a row. The colorimetric plate 3 here is a pure color plate, and there are no less than 12 types of color plates according to the color classification.

[0034] like Figure 1~2 As shown, the inserting plate 1 includes a transverse plate 11 and an inserting plate 14 disposed in the middle of both ends of the transverse plate 11, and the inserting plate 14 is adapted to the transverse splicing groove 25. The inserting plate 14 allows the inserting plate 1 and the transverse splicing groove 25 of the side wall of the side frame plate 2 to realize the quick disassembly and assembly of the inserting plate 1 and the side frame plate 2.

[0035] A rubber upper gasket is fixedly mounted on the upper surface of the plug board 14, and the upper surface of the rubber upper gasket is an arc-shaped arch surface. After the plug board 14 is inserted into the transverse splicing groove 25, the transverse splicing groove 25 squeezes the rubber upper gasket, so that the plug board 14 and the side frame plate 2 are more tightly connected.

[0036] Secondly, a plurality of jacks 12 are evenly arranged on the horizontal plate 11, and a reducing spring 13 is fixedly installed on the inner wall of the jack 12. The reducing spring 13 is composed of a plurality of rubber petal springs, and a gap is reserved between two adjacent rubber petal springs. The rubber petal springs can be adapted to test tubes of different diameters, and can also be used to compress and limit the test tubes. The rubber petal springs can clamp the test tubes well.

[0037] In addition, the transverse plates 11 are provided in several groups, and the apertures of the insertion holes 12 on the transverse plates 11 of different groups are different. For test tubes with large diameter differences, the transverse plates 11 with matching apertures can be reasonably selected.

[0038] In addition, a non-porous plate is provided below the horizontal plate 11. After the test tube passes through the upper horizontal plate 11, the non-porous plate can be used as a support for the test tube to prevent the test tube from falling.

[0039] like Figure 5 As shown, multiple side frame plates 2 and multiple tube insertion plates 1 are used for horizontal splicing, so as to flexibly expand the test tube rack in the horizontal direction, so as to facilitate the experimenter to perform colorimetric tests on more test tubes. Multiple side frame plates 2 can also be used for vertical splicing, so that the longitudinal splicing strip 22 of one side frame plate 2 is inserted into the longitudinal splicing groove 23 of another side frame plate 2, so as to expand the number of test tubes stored in the test tube rack, facilitate the storage of test tubes and other test tube tests at a later time, thereby realizing the high scalability of the test tube rack.

[0040] The working principle of the above embodiment is as follows: inserting the tube plate 1 into the transverse splicing grooves 25 of different heights, changing the height of the test tube rack to adapt to test tubes with different liquid level heights, using multiple side frame plates 2 and multiple tube plates 1 for transverse splicing to expand the test tube rack in the transverse direction, using multiple side frame plates 2 for vertical splicing, allowing the longitudinal splicing strip 22 of one side frame plate 2 to be inserted into the longitudinal splicing groove 23 of another side frame plate 2, thereby expanding the number of test tubes stored in the test tube rack.

[0041] 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.
