Description

Technical Field

[0001] The present application relates to the technical field of test tube racks, and in particular to a laboratory test tube rack. Background Art

[0002] A test tube rack is the most basic experimental instrument in a chemical laboratory used to place (sometimes test tubes can be placed on the test tube rack to observe the phenomena of an experiment) and dry test tubes.

[0003] During laboratory pretreatment, centrifuge tubes are often used in purification or solid phase extraction and nitrogen concentration steps. When there are many samples, our 12*5 (1.7cm*1.7cm per grid) test tube rack can only hold 30 15mL centrifuge tubes, which cannot be fully utilized and is inconvenient to take. In addition, too many test tube racks are used. When placing test tubes in conventional test tube racks, test tubes of the same batch are at the same height. When taking them out, the test tubes in the adjacent grids are often taken out together, which easily affects the storage of adjacent test tubes. Utility Model Content

[0004] In order to improve the problem of inconvenient access to test tubes and failure to fully utilize the effective space of the test tube rack, the present application provides a laboratory test tube rack.

[0005] The present application provides a laboratory test tube rack adopting the following technical solution:

[0006] A laboratory test tube rack comprises a side plate, an upper plate, a middle plate and a lower plate; the upper plate, the middle plate and the lower plate are integrally formed between the side plates on both sides from top to bottom in sequence; the upper plate and the middle plate are both provided with through holes for accommodating test tubes, the through holes on the upper plate correspond to the through holes on the lower plate one by one, the lower plate is provided with grid holes interlaced vertically and horizontally, and a thin plate for staggered arrangement of adjacent test tubes is installed on the middle plate.

[0007] By adopting the above technical solution, the upper plate, the lower plate, the middle plate and the side plates are all formed in an integrated manner, and the side plates on both sides are used for supporting. The test tube rack consists of three layers: the upper plate, the lower plate and the middle plate. A thin plate is installed on the middle plate so that adjacent test tubes are staggered, so that a height difference is formed between adjacent test tubes in the overall test tube rack, which makes full use of the through hole space in the entire test tube rack, and the staggered arrangement facilitates the storage and retrieval of test tubes.

[0008] Optionally, the thin plate is provided with slits, the slits are in a cross shape, and the spacing between adjacent slits is twice the spacing between adjacent through holes.

[0009] By adopting the above technical solution, a cross-shaped gap is formed, which is convenient for placing the test tube on the thin plate. The thin plate is made of plastic and has elasticity, so that the test tube can be stably placed in the through hole.

[0010] Optionally, a locking column for fastening the thin plate is also installed on the middle plate, a positioning hole is opened on the thin plate, and a guide groove is also opened on the middle plate. The locking column and the thin plate passing through the guide groove are locked together, and the locking column and the positioning hole are threadedly matched.

[0011] By adopting the above technical solution, the locking column is used to pass through the thin plate and the middle plate for locking, thereby improving the stability of the thin plate in the guide groove in the middle plate.

[0012] Optionally, a partition assembly is also installed on the upper plate, and the partition assembly includes a longitudinal plate and a transverse plate. The longitudinal plate is clamped in a groove provided in the upper plate, and the transverse plate is clamped on the longitudinal plate. The transverse plate and the longitudinal plate form a grid.

[0013] By adopting the above technical solution, the partition assembly installed in the groove of the upper plate is used for the middle or upper part of the test tube, reducing the test tube from being separated from the through hole due to being placed unstable on the middle plate. The horizontal plate and the vertical plate form a grid shape, making it easy to separate adjacent test tubes, and convenient to take and store.

[0014] Optionally, a rubber ring is installed in the through hole.

[0015] By adopting the above technical solution, the rubber ring is set in the through hole, and its shape is consistent with the shape of the through hole. The rubber ring located in the through hole helps to protect the outer wall of the test tube and reduce the wear and scratches between the tube wall and the through hole when storing the test tube.

[0016] Optionally, the transverse plate is provided with first embedding grooves at equal intervals, and the longitudinal plate is provided with second embedding grooves matching the first embedding grooves at equal intervals, and the first embedding grooves and the second embedding grooves are snap-fitted.

[0017] By adopting the above technical solution, the first embedding groove and the second embedding groove are mutually clamped, thereby improving the clamping degree between the transverse plate and the longitudinal plate.

[0018] Optionally, a pad is fixedly installed on the bottom of the lower plate.

[0019] By adopting the above technical solution, the bottom of the lower plate and the cushion block are formed in one piece, and the installed cushion block is used to buffer and protect the lower plate, so that the entire test tube rack remains in a horizontal state.

[0020] Optionally, the diameter of the grid holes is smaller than the diameter of the through holes.

[0021] By adopting the technical solution, the bottom of the test tube can be placed conveniently to prevent the test tube from leaking out of the grid holes.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. Compared with the traditional method of placing the test tubes in the test tube rack, the test tubes are all at the same height, and the adjacent test tubes squeeze each other, which affects the placement of the test tubes in the adjacent grids during storage. The thin plates on the upper plate, lower plate and middle plate are used to abut the bottom of the test tubes, and the adjacent test tubes form a staggered height difference, which fully utilizes the space of the through holes in the test tube rack and improves the space utilization rate of the test tube rack;

[0024] 2. A thin plate is provided on the middle plate, which is placed in the test tube rack to form a height dislocation between adjacent test tubes, so as to reduce interference or influence on adjacent test tubes when taking them, and facilitate the staff to take and store them.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1 To Attachment Figure 5 This application is described in further detail.

[0033] Embodiment 1

[0034] The present application embodiment discloses a laboratory test tube rack, referring to Figure 1, including side panels 1, an upper panel 2, a middle panel 3 and a lower panel 4; the upper panel 2, the middle panel 3 and the lower panel 4 are integrally formed between the side panels 1 on both sides from top to bottom, the upper panel 2, the side panel 1, the middle panel 3 and the lower panel 4 are all made of plastic, the upper panel 2 and the middle panel 3 are both provided with through holes 5 for accommodating test tubes, the through holes 5 located in the upper panel 2 correspond to the through holes 5 located in the lower panel 4 one by one, the lower panel 4 is provided with grid holes 6 interlaced vertically and horizontally, and a thin plate 7 for staggered arrangement of adjacent test tubes is installed on the middle panel 3.

[0035] A conventional test tube rack can hold 60 centrifuge tubes. Since the tube walls or caps of adjacent test tubes are usually close to each other, it is inconvenient for staff to take them out. Placing 60 centrifuge tubes in the test tube rack at intervals will result in a large amount of remaining space being unused, resulting in unreasonable use of space. In this embodiment, the upper plate 2, the lower plate 4, and the middle plate 3 are all integrated with the side plate 1. The side plates 1 on both sides are used for supporting. The test tube rack consists of three layers: the upper plate 2, the lower plate 4, and the middle plate 3. A thin plate 7 is installed on the middle plate 3, so that adjacent test tubes are staggered, so that the test tubes adjacent to each other in the overall test tube rack form a height difference, which makes full use of the through hole 5 space in the entire test tube rack, and the staggered arrangement is convenient for storing and taking out the test tubes.

[0036] See also Figure 3 As shown, a slit 8 is provided on the thin plate 7, and the slit 8 is in a cross shape. The spacing between adjacent slits 8 is twice the spacing between adjacent through holes 5. The thin plate 7 is made of plastic and has elasticity. In this embodiment, the thin plate 7 has two forms, one of which is provided with three notches corresponding to the through holes 5 at intervals, so that the test tube can pass through the grid holes 6 of the lower plate 4 to abut against each other, and two spaced cross slits 8 are provided; in the normal state of the thin plate 7, when it is not abutted by the bottom of the test tube, the slit 8 is horizontal; when the bottom of the test tube and the thin plate 7 abut against each other, it is sunken, which is convenient for the test tube to be placed in the through hole 5 and reduces the occurrence of the test tube falling out of the test tube rack; the other state is provided with three cross slits 8 at intervals, and two through holes 5 are provided at intervals. The two forms of thin plates 7 are arranged in sequence along the length direction of the middle plate 3, so that the test tube rack forms adjacent high ground dislocations, which is convenient for the staff to take and store the test tubes.

[0037] See also Figure 3As shown, a locking column 9 for fastening the thin plate 7 is also installed on the middle plate 3, a positioning hole 10 is provided on the thin plate 7, and a guide groove 11 is also provided on the middle plate 3. The locking column 9 and the thin plate 7 passing through the guide groove 11 are locked together, and the locking column 9 and the positioning hole 10 are threadedly matched. The plastic thin plate 7 is passed through the guide hole at one end of the middle plate 3 and passed out from the other end. Positioning holes 10 are provided at both ends of the thin plate 7, and there are two positioning holes 10 on each end of the thin plate 7. The locking column 9 passes through the upper end surface of the middle plate 3 and the thin plate 7. The locking column 9 and the middle plate 3 are threadedly locked to improve the stability of the thin plate 7 and the thin plate 7 located in the guide groove 11, which is convenient for the bottom of the test tube and the thin plate 7 on the middle plate 3 to abut against each other, thereby forming a height misalignment between adjacent test tubes.

[0038] See also Figure 5 As shown, a rubber ring 16 is installed in the through hole 5. The rubber ring 16 is sleeved in the through hole 5. Its shape is consistent with the shape of the through hole 5. The through hole 5 is square, and the rubber ring 16 is also square. The rubber ring 16 is located in the through hole 5 to help protect the outer wall of the test tube, reduce the wear and scratches between the tube wall and the through hole 5 when the test tube is stored, and extend the service life of the test tube.

[0039] See also Figure 3 As shown, the bottom of the lower plate 4 and the pads 19 are integrally formed, and four pads 19 are provided. The installed pads 19 are used to buffer and protect the lower plate 4, so that the entire test tube rack remains in a horizontal state, ensuring the stability of the test tubes when placed.

[0040] See also Figure 1 As shown, the diameter of the grid hole 6 is smaller than the diameter of the through hole 5, which is convenient for the bottom of the test tube to be placed to prevent the test tube from leaking out of the grid hole 6 and play a role of abutting the bottom of the test tube.

[0041] The implementation principle of a laboratory test tube rack in the embodiment of the present application is as follows: the thin plate 7 passes through the guide groove 11 of the middle plate 3, and is locked on the middle plate 3 by using the locking column 9. Some test tubes located in the test tube rack abut against the grid holes 6 of the lower plate 4, and the remaining test tubes abut against the cross-shaped gaps 8 of the thin plate 7, so that adjacent test tubes are staggered, which is convenient for the staff to make full use of the space of the through hole 5 of the test tube rack. At the same time, the test tubes with different heights do not affect or interfere with each other, which is convenient for taking and storing.

[0042] Embodiment 2

[0043] See also Figure 2 and Figure 4As shown, on the basis of the structure of the first embodiment, a partition assembly 12 is further installed on the upper plate 2, and the partition assembly 12 includes a longitudinal plate 14 and a transverse plate 13. The longitudinal plate 14 is clamped in a groove 15 provided on the upper plate 2, and the groove 15 can be any one of a T-shape, a square shape or an arc shape. In this embodiment, the groove 15 is a square shape, and the transverse plate 13 is clamped on the longitudinal plate 14, and the transverse plate 13 and the longitudinal plate 14 form a grid. The partition assembly 12 installed in the groove 15 of the upper plate 2 is used for the middle or upper part of the test tube, reducing the occurrence of the test tube being separated from the through hole 5 due to being placed in an unstable position on the middle plate 3. The grid shape formed by the transverse plate 13 and the longitudinal plate 14 makes it easy to separate adjacent test tubes, and convenient to take and store.

[0044] See also Figure 4 As shown, first embedding grooves 17 are equidistantly provided on the transverse plate 13, and second embedding grooves 18 matching the first embedding grooves 17 are equidistantly provided on the longitudinal plate 14. The first embedding grooves 17 and the second embedding grooves 18 have the same specifications and sizes, and the first embedding grooves 17 and the second embedding grooves 18 are snap-fitted together. The first embedding grooves 17 and the second embedding grooves 18 are snap-fitted to each other, thereby improving the tightness between the transverse plate 13 and the longitudinal plate 14.

[0045] The implementation principle of this embodiment is as follows: a groove 15 is provided on the end surface of the upper plate 2, the longitudinal plate 14 is clamped in the groove 15, the transverse plate 13 and the longitudinal plate 14 are clamped to each other through the first embedding groove 17 and the second embedding groove 18, so as to improve the firmness between the transverse plate 13 and the longitudinal plate 14, and the formed grid shape is convenient for each test tube located in the through hole 5 to be separated separately, so as to improve the independence of each test tube placed in the test tube rack, and at the same time, the extended length of the transverse plate 13 and the longitudinal plate 14 plays a limiting role on the test tube, so as to improve the stability of the test tube placed in the test tube rack.
