Description

Technical Field

[0001] The present invention relates to the technical field of test tube racks, and particularly to a retractable bracket. Background Art

[0002] A test tube rack is a commonly used laboratory instrument for vertically placing centrifuge tubes. Centrifuge tubes of different specifications need to be placed stably on a corresponding test tube rack.

[0003] A filter cartridge is a tubular cartridge pre-filled with packing material. A liquid sample can flow through the packing material, and by selecting a solvent with an appropriate polarity, the target substance in the sample can be washed and eluted to remove impurities. It is commonly used in pretreatment steps such as sample impurity removal and desalting. When using a filter cartridge, centrifuge tubes of different specifications need to be placed below it to collect waste liquid or eluate. The lower end of the filter cartridge needs to be suspended above the centrifuge tube, so a special filter tube bracket is required to be used in combination with multiple sets of centrifuge tube racks stacked together.

[0108] A centrifuge tube is a common experimental container used in laboratory and industrial applications. It is usually used to separate and analyze particles or components in liquid suspensions, and uses centrifugal force to separate the particles or components in the sample.

[0109] A filter cartridge is a tubular cartridge with pre-filled packing. It has a similar appearance to a centrifuge tube and has an opening at the lower end. The liquid sample can flow through the packing. By selecting a solvent with an appropriate polarity, the target substance in the sample can be eluted and purified. It is often used in pretreatment steps such as sample purification and desalting. When using a filter cartridge, centrifuge tubes 7 of different specifications need to be placed below it to collect waste liquid or eluate.

[0110] Since the filter cartridge needs to be used in conjunction with a centrifuge tube, and both the filter cartridge and the centrifuge tube have multiple specifications. For example, centrifuge tubes of 1.5 ml, 4 ml, and 15 ml have different outer diameters respectively. Therefore, a device that can adapt to multiple specifications of filter cartridges and centrifuge tubes needs to be developed. In addition, the device also needs to be convenient for storage and assembly.

[0111] The present invention relates to a collapsible bracket 100, as Figure 1-3 shown. The collapsible bracket 100 includes a base 1, a centrifuge tube holder 3, and a filter column holder 2. The base 1 is used to support the bottom end of the centrifuge tube 7, and the centrifuge tube holder 3 can fix the top end of the centrifuge tube 7. The filter column holder 2 is used to install the filter cartridge 8. The base 1, the centrifuge tube holder 3, and the filter column holder 2 can be assembled together under the storage device or used in cooperation in the working state, and the operation is very simple.

[0112] Specifically, as Figure 2 shown, the base 1 is provided with a plurality of centrifuge tube placement grooves 111. The centrifuge tube placement grooves 111 are formed by recessing the top surface of the base 1 and can accommodate the bottom end of the centrifuge tube 7. Different numbers are respectively set beside each centrifuge tube placement groove 111, which is convenient for recording experimental data and cooperating with the filter cartridge 8.

[0113] The centrifuge tube bracket 3 is provided with a plurality of centrifuge tube mounting holes 31, and the plurality of centrifuge tube mounting holes 31 penetrate the centrifuge tube bracket 3 in the vertical direction. Continuing to refer to Figure 2 , the plurality of centrifuge tube mounting holes 31 and the plurality of centrifuge tube placement grooves 111 are respectively aligned in the vertical direction, and the centrifuge tube mounting holes 31 are used to fix the top ends of the centrifuge tubes 7. A number is also set beside each centrifuge tube mounting hole 31, and the numbers of the centrifuge tube mounting holes 31 correspond one by one to the numbers of the centrifuge tube placement grooves 111 to prevent inversion.

[0114] The filter column bracket 2 is provided with a plurality of filter column mounting holes 21, and the plurality of filter column mounting holes 21 penetrate the filter column bracket 2 in the vertical direction and are respectively aligned with the plurality of centrifuge tube mounting holes 31 in the vertical direction. The plurality of filter mounting holes are used to install the filter columns 8.

[0115] The collapsible bracket 100 can be switched between a storage state and a use state. In the storage state, the filter column bracket 2, the centrifuge tube bracket 3 and the base 1 can be stacked in the vertical direction, and two adjacent ones are detachably connected.

[0116] In the use state, the filter column bracket 2 is located above the centrifuge tube bracket 3 and is detachably connected to the centrifuge tube bracket 3, and the centrifuge tube bracket 3 is located on the base 1 and is detachably connected to the base 1. In the use state, the plurality of filter column mounting holes 21, the plurality of centrifuge tube mounting holes 31 and the plurality of centrifuge tube placement grooves 111 are respectively aligned in the vertical direction from top to bottom. The plurality of filter columns 8 are respectively located above the plurality of centrifuge tubes 7, and the centrifuge tubes 7 receive the liquid filtered by the filter columns 8.

[0117] In one embodiment, the base 1 includes a base body 11 and two support members 12. Among them, the base body 11 is a quadrangular prism extending in the first direction, and the plurality of centrifuge tube placement grooves 111 are arranged in two rows and are formed by recessing from the top surface of the base body 11, and the two rows of centrifuge tube placement grooves 111 are spaced apart. As a preferred solution, a drain hole is further provided at the bottom surface of the centrifuge tube placement groove 111, and the drain hole extends to the bottom surface of the base body 11. After the liquid accidentally falls into the centrifuge tube placement groove 111, it can flow out from the drain hole.

[0118] A plurality of first centrifuge tube observation holes 112 are further provided on the side surface of the base body 11, and the plurality of first centrifuge tube observation holes 112 are respectively recessed from the side surface of the base 1 to the plurality of centrifuge tube placement grooves 111 and are used to penetrate the liquid collection condition in the centrifuge tube 7.

[0120] The two support members 12 are respectively connected to two ends of the seat body 11 along the first direction and extend vertically beyond the top surface of the seat body 11. That is to say, the tops of the two support members 12 are higher than the top surface of the seat body 11.

[0121] In the storage state, the filter column bracket 2 and the centrifuge tube bracket 3 may be arranged in a snap - connection manner, and the centrifuge tube bracket 3 and the seat body 11 may also be arranged in a snap - connection manner. In the use state, the two ends of the centrifuge tube bracket 3 are respectively snap - connected to the two support members 12, so that the centrifuge tube bracket 3 and the seat body 11 are arranged at intervals. The filter column bracket 2 may also be snap - connected to the centrifuge tube bracket 3.

[0122] In Figure 4 and Figure 5 In the specific embodiment shown, there are two sliding grooves 113 on the top surface of the seat body 11, and the two sliding grooves 113 are open towards the same side surface of the seat body 11.

[0123] Each support member 12 respectively includes a support column 121 and a clamping foot 122. Among them, the support column 121 is a plate - shaped member extending vertically, and the dimension of the support column 121 along the second direction is the same as the width dimension of the seat body 11 along the second direction. The clamping foot 122 is connected to the inner side surface of the top end of the support column 121. The clamping feet 122 of the two support members 12 are respectively arranged opposite to each other, and the lengths of the two clamping feet 122 along the second direction are respectively smaller than the length dimensions of the seat body 11 and the support column 121 along the second direction.

[0124] The bottom surface of the centrifuge tube bracket 3 is provided with two first clamping grooves 33, and the two first clamping grooves 33 are located at two ends of the centrifuge tube bracket 3 along the first direction and are open towards the two ends of the centrifuge tube bracket 3.

[0125] The bottom surface of the filter column bracket 2 is provided with two sliding blocks 23. The two sliding blocks 23 are plate - shaped members extending vertically and are located at two ends of the filter column bracket 2 along the first direction, and the two sliding blocks 23 have a certain height. The top surface of the filter column bracket 2 is provided with two clamping blocks 24. The two clamping blocks 24 are respectively strip - shaped members extending along the second direction, and the two clamping blocks 24 are aligned with the two sliding blocks 23 in the vertical direction.

[0126] In the storage state, the filter column bracket 2 is located on the top surface of the base body 11, and the two sliders 23 respectively slide into the two chutes 113 from the side surfaces of the base body 11. The centrifuge tube bracket 3 is located on the top surface of the filter column bracket 2, and the two clamping blocks 24 are respectively located in the two first clamping grooves 33.

[0127] In the use state, the two first clamping grooves 33 are respectively clamped outside the clamping feet 122 of the two support members 12, and the two sliders 23 are respectively located in the two second clamping grooves 34.

[0128] In the first embodiment of the present invention, the retractable bracket 100 further includes a first adjusting piece 5. The first adjusting piece 5 is a thin sheet extending along the first direction and is provided with a plurality of first adjusting holes 51 and two first insertion holes 52. The aperture of the first adjusting holes 51 is different from the aperture of the filter column mounting holes 21, and the two first insertion holes 52 are respectively located at both ends of the first adjusting piece 5.

[0129] In the storage state, the first adjusting piece 5 is stacked between the filter column bracket 2 and the base body 11, and the two sliders 23 respectively pass through the two first insertion holes 52 and extend into the two chutes 113. During installation, the centrifuge tube bracket 3 can be first installed on the filter column bracket 2, the two sliders 23 are respectively inserted into the two insertion holes of the first adjusting piece 5, and then the sliders 23 are slid into the chutes 113 of the base body 11.

[0130] In the use state, the first adjusting piece 5 is located on the top surface of the filter column bracket 2, as Figure 2 shown, a plurality of first adjusting holes 51 and a plurality of filter column mounting holes 21 are aligned in the vertical direction, and the two clamping blocks 24 are respectively located in the two first insertion holes 52. By installing the first adjusting piece 5 above the filter column bracket 2, since the inner diameters of the first adjusting holes 51 and the filter column mounting holes 21 are different, filter cartridges 8 with different capacities can be adapted.

[0131] Select a centrifuge tube 7 with a relatively large capacity. The bottom end of the centrifuge tube 7 is located in the centrifuge tube placement groove of the base, and the top end is located in the centrifuge tube mounting hole.

[0132] In the second embodiment of the present invention, the first adjusting piece 5 is also provided with a plurality of first adjusting holes 51 and two first insertion holes 52, and the aperture of the first adjusting holes 51 is different from the aperture of the centrifuge tube mounting holes 31;

[0133] In the storage state, the first adjusting piece 5 is also stacked between the filter column bracket 2 and the base body 11. The two first insertion holes 52 are aligned with the two chutes 113 in the vertical direction, and the two sliders 23 respectively pass through the two first insertion holes 52 and extend into the two chutes 113.

[0134] In the usage state, the first adjusting piece 5 is located on the top surface of the centrifuge tube bracket 3, and the two sliders 23 respectively pass through the two first jacks 52 and extend into the two second clamping grooves 34 respectively. During installation, the sliders 23 of the filter column bracket 2 can be first inserted into the first jacks 52 of the first adjusting piece 5 and then into the two second clamping grooves 34, or the second adjusting piece 6 can be stacked on the top surface of the centrifuge tube bracket 3, and the two second jacks 62 are respectively aligned with the two second clamping grooves 34 of the centrifuge tube bracket 3 in the vertical direction. Therefore, the two sliders 23 of the filter column bracket 2 can be directly inserted into the first jacks 52 of the first adjusting piece 5 and the second clamping grooves 34 of the centrifuge tube bracket 3 respectively.

[0135] Preferably, the apertures of the above-mentioned first adjusting holes 51, the filter column mounting holes 21, and the centrifuge tube mounting holes 31 are all different.

[0136] In the storage state, the first adjusting piece 5 is located between the filter column bracket 2 and the seat body 11. The two sliders 23 respectively pass through the two first jacks 52 and extend into the two sliding grooves 113. The same as above, it will not be elaborated here.

[0137] However, in the usage state, the first adjusting piece 5 can be either on the top surface of the filter column bracket 2 or stacked on the top surface of the centrifuge tube bracket 3. When the first adjusting piece 5 is stacked on the top surface of the filter column bracket 2, the two clamping blocks 24 are respectively located in the two first jacks 52 of the first adjusting piece 5. When the first adjusting piece 5 is located on the top surface of the centrifuge tube bracket 3, the two sliders 23 respectively pass through the two first jacks 52 and extend into the two second clamping grooves 34 respectively. That is to say, the two first sliders 23, the two clamping blocks 24, the two sliding grooves 113, and the two first jacks 52 are respectively aligned in the vertical direction. The first adjusting piece 5 can adjust the aperture of the filter column bracket 2 and the aperture of the centrifuge tube bracket 3.

[0138] In the third embodiment of the present invention, the collapsible bracket 100 is further provided with a second adjusting piece 6 in addition to the above-mentioned first adjusting piece 5. Among them, the first adjusting piece 5 is provided with a plurality of first adjusting holes 51 and two first jacks 52, and the second adjusting piece 6 is provided with a plurality of second adjusting holes 61 and two second jacks 62.

[0139] In this embodiment, the aperture of the first adjusting hole 51 is different from the aperture of the filter column mounting hole 21, and is used to adjust the aperture of the filter column mounting hole 21. The aperture of the second adjusting hole 61 is different from the aperture of the centrifuge tube mounting hole 31, and is used to adjust the aperture of the centrifuge tube mounting hole 31.

[0140] In the storage state, as Figure 3As shown, the first adjusting piece 5 and the second adjusting piece 6 are respectively stacked between the filter column bracket 2 and the seat body 11. After the two sliders 23 respectively pass through the two first jacks 52 of the first adjusting piece 5 and the two second jacks 62 of the second adjusting piece 6, they extend into the two chutes 113. During installation, the first adjusting piece 5 and the second adjusting piece 6 can be first installed at the bottom end of the filter column bracket 2, and then the two sliders 23 are respectively slid into the two chutes 113.

[0141] In the use state, as Figure 4 shown, the first adjusting piece 5 is located on the top surface of the filter column bracket 2, and the two clamping blocks 24 are respectively located in the two first jacks 52. And the second adjusting piece 6 is located on the top surface of the centrifuge tube bracket 3, and the two sliders 23 respectively pass through the two second jacks 62 and respectively extend into the two second clamping grooves 34. The centrifuge tube 7 in this embodiment has a small capacity, so it can only be suspended on the second adjusting piece and the centrifuge tube bracket and cannot touch the seat body.

[0142] In the third embodiment, the first adjusting piece 5 can only be adapted to the filter column bracket 2, and the second adjusting piece 6 can only be adapted to the centrifuge tube bracket 3.

[0143] In the fourth embodiment of the present invention, which is the same as the third embodiment, the retractable bracket 100 further includes a first adjusting piece 5 and a second adjusting piece 6. The first adjusting piece 5 is provided with a plurality of first adjusting holes 51 and two first jacks 52. The second adjusting piece 6 is provided with a plurality of second adjusting holes 61 and two second jacks 62.

[0144] The difference is that the aperture of the first adjusting hole 51 is different from the apertures of the filter column mounting hole 21 and the centrifuge tube mounting hole 31. And the aperture of the second adjusting hole 61 is different from the apertures of the filter column mounting hole 21 and the centrifuge tube mounting hole 31. The first adjusting piece 5 and the second adjusting piece 6 can respectively adjust the inner diameters of the filter column mounting hole 21 and the centrifuge tube mounting hole 31. That is to say, the first adjusting piece 5 and the second adjusting piece 6 can respectively not only be adapted to the filter column bracket 2, but also be adapted to the centrifuge tube bracket 3.

[0145] In addition, the aperture of the first adjusting piece 5 and the aperture of the second adjusting piece 6 can be the same or different.

[0146] In the retracted state, which is the same as the third embodiment, the first adjusting piece 5 and the first adjusting piece 5 are respectively located between the filter column bracket 2 and the seat body 11. The two sliders 23 respectively pass through the two first jacks 52 and the two second jacks 62 and extend into the two chutes 113.

[0147] In this embodiment, as Figure 1 and Figure 4As shown, there are two usage states. In one usage state, the first adjusting piece 5 is located on the top surface of the filter column bracket 2, and the two clamping blocks 24 are respectively located in the two first jacks 52. The second adjusting piece 6 is located on the top surface of the centrifuge tube bracket 3, and the two sliding blocks 23 respectively pass through the two second jacks 62 and respectively extend into the two second clamping grooves 34.

[0148] In another usage state, the second adjusting piece 6 is detachably installed on the top surface of the filter column bracket 2, and the two clamping blocks 24 are respectively located in the two second jacks 62. The first adjusting piece 5 is installed on the top surface of the centrifuge tube bracket 3, and the two sliding blocks 23 respectively pass through the two first jacks 52 and respectively extend into the two second clamping grooves 34.

[0149] In the fifth embodiment of the present invention, on the basis of the fourth embodiment, one first adjusting piece 5 and one second adjusting piece 6 are added, that is, there are a total of two first adjusting pieces 5 and two second adjusting pieces 6.

[0150] Specifically, as Figure 1 、 Figure 3 、 Figure 4 、 Figure 9 and Figure 10 shown, the two first adjusting pieces 5 have the same shape, the two second adjusting pieces 6 have the same shape, and the two first adjusting pieces 5 and the two second adjusting pieces 6 can respectively not only be adapted to the filter column bracket 2, but also be adapted to the centrifuge tube bracket 3.

[0151] In the storage state, as Figure 3 shown, the two first adjusting pieces 5 and the two first adjusting pieces 5 are respectively located between the filter column bracket 2 and the seat body 11. During installation, the centrifuge tube bracket 3 is installed on the top surface of the filter column bracket 2. After the sliding blocks 23 of the filter column bracket 2 are respectively inserted into the first jacks 52 of the two first adjusting pieces 5 and the second jacks 62 of the two second adjusting pieces 6, the two sliding blocks 23 are respectively slid into the sliding grooves 113 and moved from one side of the seat body 11 to the top surface of the seat body 11.

[0152] This embodiment can have multiple applicable states. In one usage state, the first adjusting piece 5 adjusts the inner diameter of the filter column mounting hole 21, and the second adjusting piece 6 adjusts the inner diameter of the centrifuge tube mounting hole 31. Specifically, the first adjusting piece 5 is located on the top surface of the filter column bracket 2, and the two clamping blocks 24 are respectively located in the two first jacks 52. The second adjusting piece 6 is located on the top surface of the centrifuge tube bracket 3, and the two sliding blocks 23 respectively pass through the two second jacks 62 and respectively extend into the two second clamping grooves 34.

[0154] Specifically, the second adjusting piece 6 is located on the top surface of the filter column bracket 2, and the two clamping blocks 24 are respectively located in the two second jacks 62; while the first adjusting piece 5 is located on the top surface of the centrifuge tube bracket 3, and the two sliders 23 respectively pass through the two first jacks 52 and respectively extend into the two second clamping grooves 34.

[0155] In the third usage state, the two first adjusting pieces 5 are used to respectively adjust the inner diameters of the filter column mounting holes 21 and the centrifuge tube mounting holes 31.

[0156] Specifically, among the two first adjusting pieces 5, one first adjusting piece 5 is installed on the top surface of the filter column bracket 2, and the two clamping blocks 24 are respectively located in the two first jacks 52, while the other first adjusting piece 5 is installed on the top surface of the centrifuge tube bracket 3, and the two sliders 23 respectively pass through the two first jacks 52 of this first adjusting piece 5 and respectively extend into the two second clamping grooves 34.

[0157] In the fourth usage state, the two second adjusting pieces 6 are used to respectively adjust the inner diameters of the filter column mounting holes 21 and the centrifuge tube mounting holes 31.

[0158] Similar to the implementation manner of using the two first adjusting pieces 5 to adjust the inner diameters of the filter column mounting holes 21 and the centrifuge tube mounting holes 31, one of the second adjusting pieces 6 is located on the top surface of the filter column bracket 2, and the two clamping blocks 24 are respectively located in the two second jacks 62; the other second adjusting piece 6 is located on the top surface of the centrifuge tube bracket 3, and the two sliders 23 respectively pass through the two second jacks 62 and respectively extend into the two second clamping grooves 34.

[0159] Furthermore, the first adjusting piece 5 is provided with a first limiting hole 53, and the second adjusting piece 6 is provided with a second limiting hole 63.

[0160] The top surface of the filter column bracket 2 is provided with a first limiting block 25, while the top surface of the centrifuge tube bracket 3 is provided with a second limiting block 35, and the bottom surface is provided with a recessed first limiting groove 36.

[0161] The first limiting hole 53, the second limiting hole 63, the first limiting block 25 and the second limiting block 35 are aligned in the vertical direction.

[0162] In the storage state, the centrifuge tube bracket 3 is located on the top surface of the filter column bracket 2, and the first limiting block 25 is clamped in the first limiting groove 36, increasing the stability of the centrifuge tube bracket 3 and the filter column bracket 2.

[0163] In the usage state, if the first adjusting piece 5 is located on the top surface of the filter column bracket 2, the two clamping blocks 24 are respectively located in the two first jacks 52 of the first adjusting piece 5, and the first limiting block 25 on the top surface of the filter column bracket 2 is clamped in the first limiting hole, further increasing the stability of the first adjusting piece 5 and the filter column bracket 2.

[0164] If the second adjusting piece 6 is located on the top surface of the centrifuge tube bracket 3, the two sliding blocks 23 of the filter column bracket 2 respectively pass through the two second jacks 62 of the second adjusting piece 6 and respectively extend into the two second clamping grooves 34, and the second limiting block 35 of the centrifuge tube bracket 3 is clamped in the second limiting hole of the second adjusting piece 6.

[0165] Of course, if the first adjusting piece 5 is installed on the top surface of the centrifuge tube bracket 3, in the same operation mode, the two sliding blocks 23 of the filter column bracket 2 respectively pass through the two first jacks 52 of the first adjusting piece 5 and then are inserted into the two second clamping grooves 34, and the second limiting block 35 on the top surface of the centrifuge tube bracket 3 is clamped in the first limiting hole.

[0166] If the second adjusting piece 6 is installed on the top surface of the filter column bracket 2, the two clamping blocks 24 of the filter column bracket 2 are respectively located in the two second jacks 62 of the second adjusting piece 6, and the first limiting block 25 is clamped in the second limiting hole of the second adjusting piece 6.

[0167] As a preferred solution, the retractable bracket 100 further includes a top cover 4, and the top cover 4 can be used alone in combination with the filter column bracket 2, the centrifuge tube bracket 3 and the base 1, or can be used in combination with the first adjusting piece 5 and the second adjusting piece 6.

[0168] In the illustrated embodiment, two third clamping grooves 43 and a second limiting groove 42 are provided on the bottom surface of the top cover 4. The top surface of the top cover 4 is the side facing up in the storage state, and the bottom surface is the side facing down in the storage state. For the convenience of distinction, the bottom surface of the top cover 4 is defined as the first side surface.

[0169] Two sunken third clamping grooves 43 are provided on the first side surface of the top cover 4, as Figure 11 and Figure 12 shown. The two third clamping grooves 43 are located at both ends of the top cover 4 along the first direction and are vertically aligned with the two clamping feet 122 and the two sliding blocks 23. A groove 41 with a relatively large area and a second limiting groove 42 surrounded by the groove 41 are provided in the middle area of the top cover 4, and the second limiting groove 42 is vertically aligned with the first limiting block 25 and the second limiting block 35.

[0170] In the storage state, the two first adjusting pieces 5 and the two second adjusting pieces 6 are located on the top surface of the seat body 11. The sliding blocks 23 of the filter column bracket 2 pass through the first jack 52 and the second jack 62 and enter the sliding groove 113. The centrifuge tube bracket 3 is installed on the top surface of the filter column bracket 2 and is located at the bottom surface of the two clamping feet 122. The two clamping blocks 24 are respectively located in the two first clamping grooves 33, and the first limiting block 25 is located in the first limiting groove 36. The top cover 4 covers the support member 12, and the two clamping feet 122 are respectively clamped in the two third clamping grooves 43 of the top cover 4. The second limiting block 35 on the top surface of the centrifuge tube 7 is located in the second limiting groove 42 of the top cover 4, and the centrifuge tube bracket 3 and the top cover 4 are clamped and connected.

[0171] In the use state, the centrifuge tube bracket 3 is located above the seat body 11, and the two first clamping grooves 33 are respectively clamped outside the clamping feet 122 of the two support members 12. The filter column bracket 2 can be installed above the centrifuge tube bracket 3, and the two sliding blocks 23 are respectively located in the two second clamping grooves 34. In another case, if it is necessary to replace the centrifuge tube 7, the filter column bracket 2 can also be disassembled from the centrifuge tube bracket 3 and the filter column bracket 2 can be placed at the top cover 4.

[0172] The top cover 4 needs to be inverted. As Figure 12 shown, after the top cover 4 is inverted, its first side faces upward, and the two sliding blocks 23 of the filter column bracket 2 are respectively installed in the two third clamping grooves 43 of the top cover 4. The filtered liquid of the filter cartridge 8 in the filter column bracket 2 can drip into the groove 41 of the top cover 4.

[0173] Furthermore, a first magnetic member 123 is embedded in the clamping foot 122, a second magnetic member 37 is embedded in the first clamping groove 33 of the centrifuge tube bracket 3, and a third magnetic member 44 is embedded in the third clamping groove 43 of the top cover 4. The magnetic properties of the first magnetic member, the second magnetic member, and the third magnetic member 44 are opposite.

[0174] In the storage state, the top cover 4 covers the centrifuge tube bracket 3, the clamping foot 122 is clamped in the third clamping groove 43 of the top cover 4, and the first magnetic member 123 in the clamping foot 122 attracts the third magnetic member 44 in the third clamping groove 43, increasing the stability.

[0175] In the use state, the centrifuge tube bracket 3 is connected to the clamping foot 122, the first clamping groove 33 of the centrifuge tube bracket 3 is clamped outside the clamping foot 122, and the second magnetic member 37 in the first clamping groove 33 attracts the first magnetic member 123 of the clamping foot 122, providing a tight fixing effect and a supporting effect.

[0176] To prevent the reverse insertion of the centrifuge tube bracket 3 or the filter column bracket 2, as a preferred solution, the two feet 122 can be set to different shapes. For example, the feet 122 can be set to different lengths, and the two first card slots 33 of the centrifuge tube bracket 3 are also set to different shapes respectively. The two feet 122 can be inserted into the two first card slots 33 to prevent reverse operation.

[0177] Of course, the two second card slots 34 on the top surface of the centrifuge tube bracket 3 can also be set to different shapes. For example, the widths or lengths of the two second card slots 34 are different, and the two sliders 23 at the bottom end of the filter column bracket 2 need to match the two second card slots 34 one by one and be set to different shapes.

[0178] Similarly, the two first jacks 52 of the first adjusting piece 5, the two second jacks 62 of the second adjusting piece 6, and the two sliding grooves 113 of the seat body 11 need to match the shape of the slider 23 one by one to avoid reverse insertion, ensuring that the positions of the multiple filter column mounting holes 21, the multiple centrifuge tube mounting holes 31, the multiple first adjusting holes 51, the multiple second adjusting holes 61, and the multiple centrifuge tube placement grooves 111 correspond to each other to form a complete filtering device.

[0179] The retractable bracket of the present invention is equipped with two kinds of adjusting pieces and can be compatible with multiple specifications of centrifuge tubes and filter columns. In addition, the retractable bracket can be assembled and stored, which saves more storage space compared with traditional multiple centrifuge tube racks. The centrifuge tube bracket, the seat body, and the filter column bracket are respectively provided with observation windows, which are convenient for observing the volume and state of the liquid in the filter columns and centrifuge tubes.

[0180] The preferred embodiments of the present invention have been described in detail above. However, it should be understood that if necessary, aspects of the embodiments can be modified to adopt aspects, features, and concepts of various patents, applications, and publications to provide additional embodiments.

[0181] In view of the above detailed description, these and other changes can be made to the embodiments. Generally speaking, in the claims, the terms used should not be considered as limited to the specific embodiments disclosed in the specification and the claims, but should be understood to include all possible embodiments and the entire equivalent scope enjoyed by these claims.

[0182] Those of ordinary skill in the art can understand that the above embodiments are specific embodiments for implementing the present invention, and in actual applications, various changes can be made in form and details without departing from the spirit and scope of the present invention.
