Technical Field
[0001] This utility model relates to the field of auxiliary tool technology, and in particular to a tube rack for assisting in fastening caps. Background Technology
[0002] In biological laboratories, capped experimental tubes (such as centrifuge tubes) are frequently used. The large volume of tubes used involves numerous capping actions, which is not only time-consuming but can also cause serious damage to the fingers of laboratory personnel over time. Furthermore, some instruments require manually tightening the caps on a large number of tubes. The specific steps include: placing the tubes on a rack → picking up the tubes → tightening the caps → placing the tubes back on the rack. This process is repeated multiple times, involving frequent picking up, tightening, and putting down of the tubes, making it tedious and inefficient. Summary of the Invention

The base surface has at least one row of recessed tube holes, and the upper sidewall of each tube hole has a groove for fixing experimental tubes. The cover plate is connected to the base via a pivot and is positioned on one side of the tube holes along the arrangement direction of the holes. A row of guide protrusions is provided on the cover plate facing the tube holes. The guide protrusions ensure that when the cover plate presses the cap of the experimental tube toward the tube in the hole, any tube cap is positioned between two guide protrusions, thus guiding the tube cap.

[0006] Optionally, the set of retractable limiting protrusions are symmetrically arranged at both ends of the cover plate.
[0007] Optionally, when not subjected to external force, the limiting protrusion restricts the cover plate to a position perpendicular to the base surface. When subjected to external force or squeezed by the cover plate, the limiting protrusion retracts into the base with the external force.
[0008] Optionally, the limiting protrusion is disposed in the recess of the base, and a spring is connected to the end of the limiting protrusion located in the recess.
[0009] Optionally, the tube hole positions are arranged in two rows, and the two rows of tube hole positions are respectively arranged on two sides of the cover plate.

[0013] Optionally, the contact surface of the guide protrusion and the tube cover is an inclined surface, and the distance between the top ends of any two guide protrusions is slightly greater than the width of the corresponding position of the tube cover.
[0014] Optionally, the guide protrusion is a triangular protrusion, and the top end of the guide protrusion is provided in a circular chamfer shape.
[0015] The technical scheme of the utility model can include the following beneficial effects:
[0016] The tube rack provided by the utility model can limit the rotation of the experimental tube by arranging grooves at the upper end of the tube hole position of the base, and the position of the tube cover and the experimental tube during the process of buckling the tube cover is limited, which is beneficial to the accurate buckling of the experimental tube. In addition, the rotation of the experimental tube placed in the hole position is limited due to the arrangement of the grooves, so that the experimental tube with a screw cover can be directly screwed onto the experimental tube after being placed in the hole position, and the operation is simple and convenient. Therefore, the tube rack of the utility model can assist in buckling the experimental tube, and solves the technical problem of tedious work in buckling the experimental tube manually in the prior art.

[0023] In order to make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme of the utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the scope of the utility model.
[0024] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can be a middle element. When an element is referred to as "connected to" another element, it can be directly connected to the other element or there can be a middle element.
[0025] When doing quantitative detection in the laboratory, for example, concentration quantitative detection of nucleic acid extraction products or document construction products, the detection reagent (such as Qubit reagent) and the detection object (nucleic acid extraction product or document construction product) are loaded into a centrifugal tube (also known as Qubit tube), then the centrifugal tube is capped, and finally the centrifugal tube with the detection reagent and the detection object is placed into a quantitative detection instrument for quantitative detection. In this detection, if the detection objects of multiple biological samples need to be quantitatively detected, it involves the operation of continuously capping the centrifugal tubes of multiple biological samples, and the capping auxiliary operation of the experimental tube in the technical scheme is suitable for the capping of the centrifugal tube.
[0026] As shown in Figure 1 , Figure 2 The utility model provides a pipe rack of auxiliary cover, including base 1 and cover plate 2, the base surface of base 1 is provided with two rows of concave pipe hole position 3, and the pipe hole position 3 can accommodate experimental tube ( Figure 1 and 2(Not shown in the image) The upper side wall of the tube hole position 3 is provided with a groove 4 for fixing the experimental tube. The cover plate 2 is connected to the base 1 through the rotating shaft 8 and is arranged between two rows of tube hole positions 3 along the arrangement direction of the tube hole positions 3. Each side of the cover plate 2 (facing the tube hole position 3) is provided with a row of guide protrusions 5. The guide protrusions 5 ensure that when the cover plate 2 presses the tube cap of the experimental tube into the tube hole position 3, any tube cap is located between two guide protrusions 5, thereby guiding the tube cap.
[0027] As an alternative implementation, depending on the required number of experimental tubes, the base 1 may also have only one row of tube holes 3 on one side of the cover plate 2, and correspondingly, only one row of guide protrusions 5 on the side of the cover plate 2 facing the tube holes 3.
[0028] Furthermore, for cases where a large number of test tubes need to be operated, if three or more rows of tube holes 3 are set on the base, then a cover plate 2 is set accordingly, so that each row of tube holes 3 corresponds to a side of a cover plate 2 with a corresponding guide protrusion 5. Through the coordinated arrangement of the cover plate 2 and the tube holes 3, the tubes used in the experiment are covered.
[0029] Specifically, such as Figure 3 As shown, a groove 4 is provided at the upper end of the tube hole 3 of the base 1 to limit the experimental tube and prevent it from rotating. A corresponding guide protrusion 5 is provided on the cover plate 2. During the process of capping the experimental tube, the positions of both the tube cap and the experimental tube are limited, eliminating the need for manual fixing of the tube cap and effectively solving the problem of tube cap tilting during capping. Figure 4 As shown, the groove 4 limits the rotation of the experimental tube placed in the tube hole position 3. After the experimental tube II 13 with the screw cap fastened is placed in the tube hole position, the tube cap II 14 can be directly fastened onto the experimental tube, making the operation simple and convenient.
[0030] As an optional implementation, a set of retractable limiting protrusions 6 are provided on the side of the cover plate 2 facing the pipe hole position 3. Figure 2 and Figure 3 Two rows of recessed pipe holes 3 are provided on the base surface of the middle base 1, and a row of guide protrusions 5 are provided on each side of the cover plate 2. For example, a set of retractable limiting protrusions 6 are provided on each side of the cover plate 2.

[0031] Understandably, if only one row of recessed pipe hole positions 3 is provided on the base surface of the base 1, and one row of guide protrusions 5 is provided on one side of the cover plate 2, a set of retractable limiting protrusions 6 is provided on one side of the cover plate 2.
[0032] Here, "a group" can be understood as two or more. It can be understood that if "a group" is two, one retractable limiting protrusion 6 can be respectively arranged at both ends of the cover plate 2. Of course, if "a group" is more than two, a plurality of retractable limiting protrusions 6 can be respectively arranged at both ends of the cover plate 2.
[0033] Specifically, a group of limiting protrusions 6 is used to limit the position of the cover plate 2 from both sides of the cover plate 2, and each group of limiting protrusions 6 is symmetrically arranged on both sides of the cover plate 2 to limit the position of the cover plate 2 in the non-use state.
[0034] As an optional embodiment, the limiting protrusion 6 limits the position of the cover plate 2 to be perpendicular to the base surface when not subjected to external force, and the limiting protrusion 6 is retracted into the base 1 along with the external force when subjected to external pressure or extrusion of the cover plate 2.
[0035] As an optional embodiment, the limiting protrusion 6 is arranged in the recess 10 of the base 1, and the end of the limiting protrusion 6 in the recess 10 is connected to a spring 9.
[0036] Specifically, the lower end of the limiting protrusion 6 is connected to the spring 9, the spring 9 is arranged in the recess 10 of the base 1, and the limiting protrusion 6 is vertically arranged on both sides of the cover plate 2 when not subjected to external force, limiting the cover plate 2 to be perpendicular to the base surface. When subjected to external pressure or extrusion of the cover plate 2, the limiting protrusion 6 is retracted into the recess 10 along with the spring, and the rotation of the cover plate 2 is not limited.
[0037] As an optional embodiment, the pipe hole site 3 is arranged in two rows, and the two rows of pipe hole sites 3 are respectively arranged on both sides of the cover plate 2. One row of guide protrusions 5 is arranged on each side of the cover plate 2.
[0038] Specifically, two rows of pipe hole sites 3 are arranged, for example, 8 hole sites 3 are arranged in each row for placing Qubit tubes, which can operate a large number of Qubit tubes at a time, and save space when multiple modules are combined. The cover plate 2 is arranged between the two rows of hole sites and is connected to the base 1 through the rotating shaft 8, and can rotate freely left and right.
[0039] As an optional embodiment, the groove 4 at each pipe hole site 3 is arranged in two, and the two grooves 4 are symmetrically arranged.
[0040] Specifically, two grooves 4 are symmetrically arranged, corresponding to the protruding structure on the experimental tube, and limiting the experimental tube in the rotation direction.
[0041] As an optional embodiment, the upper end of each hole site 3 is provided with a protruding edge 7 relative to the base surface, and the edge 7 is provided with a notch corresponding to the groove 4.
[0042] Specifically, the upper end of the hole site is provided with a flange corresponding to the structure of the experimental tube, so as to stably place the experimental tube.
[0043] As an optional implementation, the contact surface of the guide protrusion 5 with the pipe cover 2 is an inclined slope, and the distance between the top ends of any two guide protrusions 5 is slightly greater than the width of the corresponding position of the pipe cover.
[0044] As an optional implementation, the guide protrusion 5 is a triangular protrusion, and the top end of the guide protrusion 5 is provided in a circular chamfer shape.
[0045] Specifically, as shown in Figure 3 The guide protrusion 5 defines the position of the pipe cover I 12, so that during the buckling of the experimental tube I 11, the pipe cover 12 does not need to be manually fixed, and the problem of tilting of the pipe cover during buckling can be effectively solved.
