Description

Technical Field

[0001] The present application relates to the field of laboratory instruments and equipment, and in particular to a novel reagent tube rack. Background Art

[0002] In biological and chemical experiments, reagent tubes are a very commonly used experimental equipment. There are two most common structures of reagent tubes. One is the screw-cap type, that is, the tube body and the tube cover are connected by threads to achieve the sealing of the reagent tube; the other is the continuous cover type, that is, the tube body and the tube cover are connected as a whole through a flexible material, and the reagent tube is sealed by pressing the tube cover on the tube mouth. The reagent tube rack is a device for orderly accommodating reagent tubes. Usually, a rectangular array of placement holes is provided on the reagent tube rack, and the reagent tubes are placed in the placement holes. For continuous cover reagent tubes, the natural state when the tube cover is opened is that there is a certain angle upward. The tube cover of a reagent tube may block the top of another adjacent reagent tube, causing the sample to drip on the tube cover when the pipetting workstation performs pipetting operations on the reagent tube, or even the tube cover covers the tube mouth and cannot be pipetted. In order to avoid this situation, in current practical operations, two reagent tubes with connected lids are often placed one by one and one row of placement holes apart to ensure that there is no position interference problem between the reagent tubes adjacent to the left and right and the front and back. This operation not only reduces the utilization rate of the reagent tube rack, but is also not conducive to rapid batch pipetting or sample addition.

[0003] The existing domestic utility model patent, patent name: a practical multifunctional test tube rack device, publication number CN202021784225.8, discloses a practical multifunctional test tube rack device, the test tube rack is based on an ordinary test tube rack, a lower buckle is set on the left side of the test tube rack, the number of buckles matches the number of test tube rows, and a threaded parallel pillar is set on the right side of the test tube rack, the number of pillars matches the number of test tube rows, and the threaded parallel pillars are provided with parallel fastening nuts: the test tube cover bracket is composed of a pillar and a main plate, the pillar is supported by a plate of a certain thickness, a slot is provided in the middle of the plate, the top of the plate is connected to a cylinder, the top of the cylinder is threaded and equipped with a fastening nut, the cylinder of the pillar passes through the small hole on the right side of the main plate, and is fixed by a fastening nut, and the main plate is provided with a test tube cover hole and a spring clip that match the test tube rack. The test tube cover hole of the test tube rack is used to place the test tube cover when it is set, and the test tube cover is clamped by the spring clip, but the test tube cover hole needs to occupy the horizontal plane space of the test tube rack, and still fails to improve the space utilization of the test tube rack.

[0004] Therefore, in order to solve the above problems, the utility model proposes a novel reagent tube rack, which can limit the tube cover to the side of the tube body, so that there will be no position interference between adjacently placed reagent tubes. Utility Model Content

[0011] In a preferred technical solution of the present application, the end of the hook is bent upward to form a right-angled hook at 90 degrees.

[0012] In a preferred technical solution of the present application, the mounting plate is vertically arranged on the upper plate, and the setting height of the hook claw is set according to the length of the connecting part, so that the tube cover of the reagent tube is hung on the hook claw after being placed in the placement hole.

[0030] Embodiment 1

[0031] In experimental operations, multi-throughput pipettes or pipetting workstations are often used for pipetting or sample addition. Reagent tubes for containing reagents include two types, one is a screw-cap type and the other is a continuous-cap type. When using a screw-cap reagent tube, due to the knob cover, both hands are required to open the tube cover of the reagent tube, which is very inconvenient for operators to operate. Therefore, the application advantage of the continuous-cap reagent tube is more obvious, and its application is becoming more and more common. However, the use of the continuous-cap reagent tube also has the following problems: that is, when the continuous-cap reagent tube is placed in a reagent tube rack, the natural state of the tube cover when the tube cover is opened is a certain upward angle. The tube cover of one reagent tube may block the top of another adjacent reagent tube, causing the sample to drip on the tube cover when the pipetting workstation performs pipetting or sample addition operations on the reagent tube, or even the tube cover covers the tube mouth and the sample cannot be added. In order to avoid this situation, in current actual operations, two reagent tubes with connected lids are often placed one by one and one row by one, to ensure that there is no position interference between the adjacent reagent tubes on the left and right and front and back. To solve the above problem, the embodiment of the present application has an inventive design, which is introduced below with reference to the accompanying drawings.

[0032] See also Figures 1 to 6 .

[0033] The novel reagent tube 2 of the embodiment of the present application comprises a frame 1, on which a plurality of placement holes 11 for accommodating the reagent tubes 2 are provided. The reagent tubes 2 comprise tube covers 21 and tube bodies 22 connected by a connecting portion 23. A tube cover holder 3 for receiving the tube cover 21 is provided beside each placement hole 11.

[0034] Furthermore, in order to stably place the reagent tube 2, the aperture size and shape of the placement hole 11 of the embodiment of the present application are set according to the reagent tube 2. According to the actual application, when a large-sized reagent tube 2 needs to be placed, the aperture of the placement hole 11 can be set to an adaptive large aperture, and when a small-sized reagent tube 2 is placed, the aperture of the placement hole 11 is set to a smaller aperture according to the reagent tube 2. Specifically, the aperture of the placement hole 11 is larger than the reagent tube 2, and a certain gap is reserved between the outer tube wall of the reagent tube 2 and the edge of the placement hole 11, so as to facilitate the removal of the reagent tube 2 and stably place the reagent tube 2.

[0035] If the tube body 22 of the reagent tube 2 is a circular tube body 22, the placement hole 11 is set as a circular placement hole 11. If the tube body 22 of the reagent tube 2 is a square tube body 22, the placement hole 11 is set as a square placement hole 11. The embodiment of the present application does not limit the shape and size of the placement hole 11.

[0036] The embodiment of the present application shows the main structure of a reagent tube 2 with a cover, wherein the reagent tube 2 includes a tube cover 21, a connecting portion 23 and a tube body 22, wherein the connecting portion 23 can be bent and folded, and the tube cover 21 is connected to the tube body 22 via the foldable connecting portion 23, the width of the tube cover 21 is W1, and the width of the connecting portion 23 is W2. Figure 3 As shown, the tube cover 21, the connecting portion 23 and the tube body 22 are made of the same material by injection molding. When the reagent tube 2 is in the initial state, the tube body 22 is placed vertically, and the tube cover 21 is connected to the left or right side of the tube body 22 in the horizontal direction. Figure 6 As shown; when the reagent tube 2 is placed on the new reagent tube rack, the tube cover 21 is received and placed on the tube cover holder 3, and the upper planes of the tube cover 21 and the opening of the tube body 22 are 90 degrees and kept in a vertical state. At this time, the upper surface of the tube cover 21 is parallel to the center line of the tube body 22 in the vertical direction, and the distance between the upper surface of the tube cover 21 and the center line of the tube body 22 is L1. The raised structure on the lower surface of the tube cover 21 is interference fit with the opening of the tube body 22, which plays a sealing role.

[0037] The novel reagent tube rack of the example of the present application has a tube cover holder 3 for storing the tube cover 21 provided beside the placement hole 11. When the reagent tube 2 is placed on the rack 1, the tube cover holder 3 can store the tube cover 21, that is, limit the tube cover 21 on the tube cover holder 3.

[0038] Furthermore, in the embodiment of the present application, when the reagent tube 2 is placed on the novel reagent tube rack, the tube cover 21 is limited on the tube cover holder 3, and the upper plane of the opening of the tube cover 21 and the tube body 22 is at 90 degrees to maintain a vertical state. At this time, the upper surface of the tube cover 21 is parallel to the center line of the tube body 22 along the vertical direction. This can avoid the tube cover 21 of a reagent tube 2 blocking the top of another adjacent reagent tube 2, causing the sample to drip on the tube cover 21 when the pipetting workstation performs pipetting or sample addition operations on the reagent tube 2, or even the tube cover 21 covers the tube opening and cannot achieve sample addition.

[0039] Beneficial effects of the embodiments of the present application: The novel reagent tube rack includes a rack body, which is provided with a plurality of placement holes for accommodating reagent tubes. The reagent tubes include tube covers and tube bodies connected by a connecting portion, and a tube cover support for storing the tube covers is provided next to each placement hole.

[0040] The tube cover holder can be used to store the tube covers of reagent tubes connected to the tube covers, so that the covers are limited to be kept beside the tube body, so that there is no position interference between adjacently placed reagent tubes, which not only improves the utilization rate of the reagent tube rack, but also makes it convenient for operators or pipetting workstations to perform rapid batch pipetting or sample addition.

[0041] Embodiment 2

[0042] The novel reagent tube rack of the first embodiment can limit the position of the tube caps of the reagent tubes, which can prevent the tube caps of the reagent tubes from affecting the adjacent reagent tubes, thereby affecting the normal progress of the experimental operation, and can increase the speed of adding samples or pipetting. It has practical application value and is worthy of promotion and application. In order to improve the application effect of the novel test tube rack of the present application, the embodiment of the present application will further invent and design the tube cap holder.

[0043] See also Figures 1 to 6 .

[0044] The novel reagent tube 2 of the embodiment of the present application comprises a frame 1, on which a plurality of placement holes 11 for accommodating the reagent tubes 2 are provided. The reagent tubes 2 comprise tube covers 21 and tube bodies 22 connected by a connecting portion 23. A tube cover holder 3 for receiving the tube cover 21 is provided beside each placement hole 11.

[0045] The tube cover support 3 of the embodiment of the present application includes a mounting plate 31 and two hook claws 32 arranged in parallel on the mounting plate 31 . The distance between the two hook claws 32 is smaller than the width of the tube cover 21 and larger than the width of the connecting portion 23 .

[0046] When the upper planes of the openings of the tube cover 21 and the tube body 22 are at 90 degrees and remain vertical, the upper surface of the tube cover 21 is parallel to the center line of the tube body 22 in the vertical direction, and the distance between the upper surface of the tube cover 21 and the center line of the tube body 22 is L2. Furthermore, the distance from the mounting plate 31 to the center of the placement hole 11 is L2.

[0047] The distance between the two hooks 32 is smaller than the width of the tube cover 21, and larger than the width of the connecting portion 23. This size limitation means that when placing the reagent tube 2 from top to bottom in the placement hole 11, the tube body 22 of the reagent tube 2 is aligned with the placement hole 11 and placed in the placement hole 11, while the connecting portion 23 and the tube cover 21 are placed downward along the position between the two hooks 32. In the embodiment of the present application, the distance between the two hooks 32 is larger than the width of the connecting portion 23, so that the reagent tube 2 can be smoothly placed in the placement hole 11, and the distance between the two hooks 32 is smaller than the width of the tube cover 21, so that the tube cover 21 can be stuck between the two hooks 32, playing the role of storing and limiting the tube cover 21. The above-mentioned structure can also facilitate the smooth removal of the reagent tube 2 after the pipetting operation is completed.

[0048] A plurality of placement holes 11 are arranged in a rectangular array, and the tube cover support 3 is arranged on the same side of each row of placement holes 11. Further, as Figure 1 As shown, the tube cover holders 3 of the same row of placement holes 11 are distributed in a straight line on their extension lines. This structural arrangement can maximize the use of the space on the upper surface of the frame 1.

[0049] The frame 1 of the embodiment of the present application includes an upper plate 12, a bottom plate 13 and a connecting column 14. The upper plate 12 and the bottom plate 13 are connected by the connecting column 14. The placement hole 11 is opened on the upper plate 12, and the bottom plate 13 is downwardly provided with an arc-shaped bottom corresponding to the placement hole 11, so as to facilitate the stable placement of the reagent tube 2.

[0050] Furthermore, the upper plate 12 and the bottom plate 13 are detachably connected, and connection holes are provided on the upper plate 12 and the bottom plate 13. The connection column 14 is a threaded connection column 14, and the connection column 14 is detachably installed on the connection hole by a nut. The detachable upper plate 12 and the bottom plate 13 can facilitate the packaging and transportation of the new reagent tube rack, that is, when packaging and transporting the new reagent tube rack of the embodiment of the present application, the rack body 1 can be disassembled, and the spatial position of the rack body 1 is convenient for transportation.

[0051] Furthermore, the upper plate 12 and the bottom plate 13 of the present application are provided with a hollow structure, and this structural arrangement can facilitate observation of the status of the reagent in the reagent tube 2 during experimental operation.

[0052] Furthermore, the end of the hook claw 32 of the embodiment of the present application is bent upward to form a right-angle hook claw 32 at 90 degrees. The right-angle hook claw 32 can limit the pipe cover 21 on the hook claw 32 more stably.

[0053] Beneficial effects of the embodiments of the present application: This embodiment is further invented and designed based on the structure of the first embodiment. In addition to achieving the beneficial effects of the first embodiment, the tube cover support of the present application includes a mounting plate and two hooks arranged in parallel on the mounting plate. The distance between the two hooks is less than the width of the tube cover and greater than the width distance of the connecting portion. This structural arrangement can facilitate the smooth placement of the reagent tube into the placement hole, so that the tube cover can be stuck between the two hooks, playing the role of storing and limiting the tube cover. It can also facilitate the removal of the reagent tube. In addition, the end of the hook is bent upward to form a 90-degree right-angle hook, which can limit the tube cover more stably on the hook.

[0054] Embodiment 3

[0055] The embodiments of the present application provide an example to introduce the novel reagent tube rack.

[0056] See also Figures 1 to 6 .

[0057] The novel reagent tube 2 of the embodiment of the present application includes a frame 1, on which a plurality of placement holes 11 for accommodating the reagent tubes 2 are provided, and the reagent tubes 2 include a tube cover 21 and a tube body 22 connected by a connecting portion 23. A tube cover holder 3 for receiving the tube cover 21 is provided beside each placement hole 11. Exemplarily, the placement hole 11 of the embodiment of the present application is a circular placement hole 11.

[0058] The embodiment of the present application shows the main structure of the reagent tube 2 with a cover, the reagent tube 2 includes a tube cover 21, a connecting portion 23 and a tube body 22, wherein the connecting portion 23 can be bent and folded, the tube cover 21 is connected to the tube body 22 through the foldable connecting portion 23, the width of the connecting portion 23 is W2, and W2 is exemplarily in the range of 5-9 mm. 6 mm is preferred in the present application.

[0059] Furthermore, in the embodiment of the present application, when the reagent tube 2 is placed on the novel reagent tube rack, the tube cover 21 is limited on the tube cover holder 3, and the upper plane of the opening of the tube cover 21 and the tube body 22 is 90 degrees to maintain a vertical state. At this time, the upper surface of the tube cover 21 is parallel to the center line of the tube body 22 along the vertical direction. This can avoid the tube cover 21 of a reagent tube 2 blocking the top of another adjacent reagent tube 2, causing the sample to drip on the tube cover 21 when the pipetting workstation performs pipetting or sample addition operations on the reagent tube 2, or even the tube cover 21 covers the tube opening and cannot achieve sample addition.

[0060] When the upper planes of the openings of the tube cover 21 and the tube body 22 are at 90 degrees and remain vertical, the upper surface of the tube cover 21 is parallel to the center line of the tube body 22 in the vertical direction, and the distance between the upper surface of the tube cover 21 and the center line of the tube body 22 is L1. Furthermore, the distance from the mounting plate 31 to the center of the placement hole 11 is L1.

[0061] The distance between the two hooks 32 is smaller than the width of the tube cover 21, and larger than the width of the connecting portion 23. This size limitation means that when placing the reagent tube 2 from top to bottom in the placement hole 11, the tube body 22 of the reagent tube 2 is aligned with the placement hole 11 and placed in the placement hole 11, while the connecting portion 23 and the tube cover 21 go down between the two hooks 32. The distance between the two hooks 32 is larger than the width of the connecting portion 23, so that the reagent tube 2 can be smoothly placed in the placement hole 11, and the distance between the two hooks 32 is smaller than the width of the tube cover 21, so that the tube cover 21 can be stuck between the two hooks 32, playing the role of storing and limiting the tube cover 21. At the same time, it is also convenient to take out the reagent tube 2.

[0062] The frame 1 of the embodiment of the present application includes an upper plate 12, a bottom plate 13 and a connecting column 14. The upper plate 12 and the bottom plate 13 are connected by the connecting column 14. The placement hole 11 is opened on the upper plate 12, and the bottom plate 13 is downwardly provided with an arc-shaped bottom corresponding to the placement hole 11, so as to facilitate the stable placement of the reagent tube 2.

[0063] The mounting plate 31 of the tube cover holder 3 is vertically arranged on the upper surface of the upper plate 12 , and the setting height of the hook claw 32 of the tube cover holder 3 is set according to the length of the connecting portion 23 , so that the tube cover 21 of the reagent tube 2 is hung on the hook claw 32 after being placed in the placement hole 11 .

[0064] Furthermore, the end of the hook 32 of the embodiment of the present application is bent upward to form a right-angle hook 32 at 90 degrees. The right-angle hook 32 can limit the pipe cover 21 on the hook 32 more stably.

[0065] Exemplarily, the frame 1 is a rectangular parallelepiped structure, and the frame 1 is 10-20 cm long, 8-15 cm wide, and 3-6 cm high.

[0066] The mounting plate 31 is a rectangular mounting plate 31 with a height of 1-2 cm and a length of 1-1.5 cm. The hook 32 is a right-angle hook 32 including a horizontal section and a vertical section. The length of the horizontal section is 3-4 mm and the length of the vertical section is 5-8 mm.
