Description

Technical Field

[0001] This invention belongs to the field of experimental equipment, specifically relating to a foldable test tube rack. Background Technology

[0002] Currently, a common problem in biological laboratories is the insufficient number of test tube rack openings, making it impossible to properly accommodate too many test tubes during experiments. Traditional single-row test tube racks have a fixed number of openings, and in the event of an unexpected situation where there are too many test tubes and not enough openings, researchers need to find new test tube racks, delaying the experimental process. Summary of the Invention

[0003] The technical problem this invention aims to solve is to provide a foldable test tube rack that can quickly transform from a single-row test tube rack to a double-row test tube rack, significantly increasing the number of holes for placing test tubes. This avoids the situation where there are not enough holes in the test tube rack during experiments. Furthermore, when storing the test tube rack, folding it into a single-row rack effectively saves storage space.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A foldable test tube rack includes a base system, a support system, and a column system; The base system includes a fixed base, a foldable base, and a base hinge device, which connects the fixed base and the foldable base together; the fixed base and the foldable base are provided with test tube support grooves; The support system includes a fixed support, a foldable support, and a support hinge device, wherein the support hinge device connects the fixed support and the foldable support together; the fixed support and the foldable support are provided with through holes that pass through the fixed support and the foldable support. The column system consists of two cylindrical columns, which fix the support system and the base system to the cylindrical columns.

[0005] Furthermore, the fixed base includes a fixed base base plate, the fixed base base plate has first column mounting holes at both ends, a first test tube bottom support groove on the fixed base base plate, and a first hinge mounting slot on one side of the fixed base base plate; the first hinge mounting slot is located on the bottom surface of the fixed base base plate. The foldable base includes a foldable base substrate, on which a second hinge mounting slot and a second test tube support slot are provided. The opening of the second test tube support slot is located on the upper bottom surface of the foldable base substrate. The second hinge mounting slot is located on the lower bottom surface of the foldable base substrate. The upside down of the foldable base substrate is determined based on its usage state.

[0006] Furthermore, the fixed bracket includes a fixed bracket base plate, with second column mounting holes at both ends of the fixed bracket base plate, a third hinge mounting slot on one side of the fixed bracket base plate, a first test tube through hole penetrating the fixed bracket base plate, and a folding bracket support column on one side of the fixed bracket base plate. The foldable bracket includes a foldable bracket base plate. A fourth hinge mounting slot is provided on one side of the foldable bracket base plate. A second test tube through hole is provided on the surface of the foldable bracket base plate. The foldable bracket can be folded upward above the fixed bracket, and the corresponding holes of the first test tube through hole and the second test tube through hole are coaxial.

[0007] Furthermore, the number of first test tube support slots on the fixed base is the same as the number of second test tube support slots on the foldable base, and the corresponding holes remain coaxial when the foldable base is folded below the fixed base. The number of support slots can be set according to the size of the fixed base and the foldable base. Furthermore, the number of first test tube through holes on the fixed support is the same as the number of second test tube through holes on the foldable support; the number of first test tube bottom grooves is the same as the number of first test tube through holes and they are coaxial vertically; the number of second test tube bottom grooves is the same as the number of second test tube through holes and they are coaxial vertically. This ensures that the test tubes can pass vertically through the test tube through holes of the fixed support and be placed in the test tube bottom grooves of the fixed base.

[0008] Furthermore, the column system is fixedly connected to the fixed base via column mounting holes on the fixed base, which can be achieved using an interference fit or adhesive bonding method; the column system is also fixedly connected to the fixed bracket via column mounting holes on the fixed support, which can also be achieved using an interference fit or adhesive bonding method. The fixed base, column system, and fixed support form a stable structure.

[0009] Furthermore, one side of the base hinge device is fixedly connected to the first hinge mounting slot on the fixed base, which can be achieved by adhesive bonding or screw connection; the other side is fixedly connected to the second hinge mounting slot on the foldable base, which can also be achieved by adhesive bonding or screw connection. The connection method ensures that the foldable base is folded under the fixed base.

[0010] Furthermore, one side of the bracket hinge device is fixedly connected to the third hinge mounting slot on the fixed bracket by adhesive bonding or screw connection; the other side is fixedly connected to the fourth hinge mounting slot on the foldable bracket by adhesive bonding or screw connection.

[0011] The foldable test tube rack of this invention features a foldable base that can rotate 180 degrees upwards around its axis and then be arranged side-by-side with a fixed base, with the opening of the test tube support groove on the foldable base facing upwards. This transforms the original single-row test tube rack into a double-row rack. Simultaneously, the foldable support can rotate 180 degrees downwards around its axis and then be arranged side-by-side with the fixed support, transforming the original single-row test tube rack into a double-row rack. After rotating 180 degrees around its axis, the side of the foldable support contacts the foldable support column on the fixed support. The foldable support column can hold the foldable support in place, preventing it from folding further, thus acting as a limit and ensuring that the foldable support remains horizontal after rotating 180 degrees.

[0012] By adopting the above solution, a single-row laboratory test tube rack can be expanded into a double-row test tube rack through a folding action, which can effectively solve the problem of insufficient test tube placement space during experiments. Attached Figure Description

The fixed bracket base plate 2101 has a first test tube through hole 2104 that penetrates through the fixed bracket base plate. A folding bracket support column 2105 is provided on one side of the fixed bracket base plate. The length of the folding bracket support column 2105 is the distance between the foldable bracket 22 and the fixed bracket 21 after folding. The folding bracket support column 2105 abuts against the side of the foldable bracket 22, so that the foldable bracket 22 can be folded 180 degrees and kept horizontal with the upper surface of the fixed bracket 21. The foldable bracket 22 includes a foldable bracket base plate 2201. A fourth hinge mounting slot 2202 is provided on one side of the foldable bracket base plate 2201. A second test tube through hole 2203 is provided on the plate surface of the foldable bracket base plate 2201. The foldable bracket 22 can be folded upward above the fixed bracket 21. The corresponding holes of the first test tube through hole 2104 and the second test tube through hole 2203 are coaxial.

[0018] In a preferred embodiment, the number of first test tube support slots 1104 on the fixed base 11 is the same as the number of second test tube support slots 1203 on the foldable base, and the corresponding holes are coaxial when the foldable base 12 is folded below the fixed base 11. The number of support slots can be set according to the size of the fixed base and the foldable base. In a preferred embodiment, the number of first test tube through holes 2104 on the fixed support is the same as the number of second test tube through holes 2203 on the foldable support; the number of first test tube bottom grooves 1104 is the same as the number of first test tube through holes 2104, and the upper and lower corresponding holes are coaxial; the number of second test tube bottom grooves is the same as the number of second test tube bottom grooves 1203, and the upper and lower corresponding holes are coaxial. This ensures that the test tubes can pass vertically through the test tube through holes of the fixed support and be placed in the test tube bottom grooves of the fixed base.

[0019] The column system 3 is fixedly connected to the fixed base 11 via the column mounting holes 1102 on the fixed base 11, which can be achieved by interference fit or adhesive bonding. The column system 3 is also fixedly connected to the fixed bracket 21 via the column mounting holes 2102 on the fixed bracket 21, which can also be achieved by interference fit or adhesive bonding. The fixed base 11, the column system 3, and the fixed bracket 21 form a stable structure.

[0020] In a preferred embodiment, one side of the base hinge device 13 is fixedly connected to the first hinge mounting slot 1103 on the fixed base 11, which can be achieved by adhesive bonding or screw connection; the other side is fixedly connected to the second hinge mounting slot 1202 on the foldable base 12, which can also be achieved by adhesive bonding or screw connection. The connection method can ensure that the foldable base 12 is folded under the fixed base 11.

[0021] In a preferred embodiment, one side of the bracket hinge device 23 is fixedly connected to the third hinge mounting slot 2103 on the fixed bracket 21, which can be achieved by adhesive bonding or screw connection; the other side is fixedly connected to the fourth hinge mounting slot 2202 on the foldable bracket 22, which can also be achieved by adhesive bonding or screw connection.

[0022] The working principle of this invention is as follows: like Figure 6 and Figure 7 As shown, a foldable test tube rack is provided. The foldable base 12 can rotate 180 degrees around its axis from bottom to top and then be arranged side by side with the fixed base 11, changing the original single-row test tube rack to a double-row arrangement. Simultaneously, the foldable bracket 22 can rotate 180 degrees around its axis from top to bottom and then be arranged side by side with the fixed bracket 21, changing the original single-row test tube rack to a double-row arrangement. After rotating 180 degrees around its axis, the side of the foldable bracket 22 contacts the foldable bracket support column 2105 on the fixed bracket 21. The foldable bracket support column 2105 can press against the side wall of the foldable bracket 22, preventing it from folding further, thus acting as a limit and ensuring that the foldable bracket 22 remains horizontal after rotating 180 degrees.

[0023] like Figure 8 As shown, the foldable test tube rack provided by this invention can hold a row of test tubes in its normal single-row state, such as... Figure 9 As shown, the present invention provides a foldable test tube rack that can be folded from a single-row test tube rack to a double-row test tube rack, capable of holding two rows of test tubes. When storing the test tube rack normally, a single-row arrangement can be used to save storage space. When an emergency requires additional test tube placement space, the invention can be folded open to form a double-row test tube rack, increasing the available space for test tubes.
