Description

Technical Field

[0001] The present disclosure relates to the technical field of test tube holders, in particular to a test tube holder for flip-top test tubes. Background Art

[0002] The test tube holder is a device for placing test tubes. The test tube holder generally comprises a test tube hole for accommodating the test tube. The diameter of the test tube hole is slightly larger than the outer diameter of the test tube so that the test tube can be inserted into the test tube hole and placed substantially vertically in the test tube holder.

[0003] Test tubes in the prior art generally include capless type, screw-on cap type and flip-top cap type. The capless type means that the test tube does not have a tube cover, and the opening at the top of the test tube is always in an open state; the screw-on cap type means that the tube cover can be installed to or separated from the opening at the top of the test tube by rotating; the flip-top cap type means that the tube cover can be installed to or separated from the opening at the top of the test tube by flipping.

[0004] For flip-top test tubes, the tube cover and the tube body are generally connected by a connector. When the tube cover is separated from the opening at the top of the tube body, the tube cover is still connected to the tube body by the connector, and does not form a completely independent part.

[0005] The test tube holder in the prior art usually has a tube cover limiting component for keeping the tube cover in an open position. When the tube cover is in the tube cover limiting component, due to the short length of the tube body, about 4 cm, the tube body usually becomes skewed and cannot remain vertical, which is not conducive to taking and placing reagents in the tube body in subsequent steps. Utility Model Content

[0006] The object of the present disclosure is to provide a test tube holder for a flip-top test tube, wherein when the tube body is installed in a test tube hole and the tube cover is held in an open position by a tube cover limiting component, the tube body is in a vertical state.

[0007] To achieve the above object, the present disclosure provides a test tube holder for a flip-top test tube, the flip-top test tube comprising a tube body, a tube cover and a connector, the tube cover being connected to the tube body via the connector, and when the tube cover is in an open position, the tube cover is located on a first side of the tube body, the test tube holder comprising:

[0008] a first plate, the first plate comprising a test tube well;

[0009] a tube cover limiting component, the tube cover limiting component is located above the first plate and on the first side of the test tube hole, and the tube cover limiting component is used to keep the tube cover in the open position;

[0010] The test tube support further comprises:

[0011] A vertical limiting surface, the vertical limiting surface is located below the first plate and corresponds to at least an edge of a first side of the test tube hole. When the tube body is installed in the test tube hole and the tube cover is held in the open position by the tube cover limiting component, the first side of the tube body abuts against the vertical limiting surface, so that the tube body is in a vertical state.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By setting the vertical limiting surface, when the tube body is installed in the test tube hole and the tube cover is kept in the open position by the tube cover limiting component, the first side of the tube body abuts against the vertical limiting surface, thereby ensuring that the tube body is in a vertical state.

For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0033] Figure 1 A schematic diagram of a flip-top test tube in the prior art is shown. The flip-top test tube 1 comprises a tube body 11, a tube cover 12 and a connector 13. The tube body 11 has an inner cavity and an opening 111 located at the upper part of the tube body 11 and connected to the inner cavity. The tube cover 12 is installed on the tube body 11 through the connector 13. Specifically, one end of the connector 13 is connected to the tube body 11, and the other end of the connector 13 is connected to the tube cover 12. The connector 13 can be bent so that the tube cover 12 can switch back and forth between the closed position and the flip-open position, and no matter which position the tube cover 12 is in, the tube cover 12 is always connected to the tube body 11 through the connector 13.

[0034] Figure 1 The tube cover 12 is in the open position, at which time the tube cover 12 does not close the opening 111 of the tube body 11, the opening 111 of the tube body 11 is in an open state, and the tube cover 12 is located at one side of the tube body 11. In an embodiment not shown, the tube cover 12 can also be in the closed position, at which time the tube cover 12 closes the opening 111 of the tube body 11, and the tube cover 12 is located at the top of the tube body 11.

[0035] like Figure 1 As shown, the opening 111 of the tube body 11 is provided with a tube opening edge 112 protruding radially outward, and the outer diameter of the tube opening edge 112 is larger than the outer diameter of other positions of the tube body 11. One end of the connector 13 can be connected to the tube opening edge 112.

[0036] exist Figure 1 As an example, the outer diameter of the tube body 11 is about 10 mm, and the length of the tube body 11 is about 40 mm.

[0037] Figure 2 A schematic diagram of a test tube holder without a vertical limiting surface provided by an embodiment of the present disclosure is shown. The test tube holder is a hollow frame, specifically, the test tube holder includes a first plate 2 and a second plate 3 spaced apart from each other, a plurality of support plates 4 are disposed between the first plate 2 and the second plate 3, two adjacent support plates 4 are spaced apart, the lower end of the support plate 4 is connected to the second plate 3, and the upper end of the support plate 4 is connected to the first plate 2. The test tube holder has a window so that the internal conditions of the test tube holder can be observed from the outside of the test tube holder, especially the installation conditions of the tube body 11 can be observed.

[0038] It should be noted that, although the test tube holder in the present embodiment is substantially in the shape of an elongated strip, in embodiments not shown, the test tube holder may also be in the shape of a circle or an annular ring.

[0039] The first plate 2 is provided with a plurality of test tube holes 21, and specifically, a test tube hole 21 can be provided between two adjacent support plates 4. The test tube hole 21 passes through the upper surface and the lower surface of the first plate 2, and the diameter of the test tube hole 21 is slightly larger than the outer diameter of the tube body 11, so that the tube body 11 can be inserted into the test tube hole 21, and the diameter of the test tube hole 21 is smaller than the outer diameter of the tube mouth edge 112, so that the tube mouth edge 112 does not fall into the test tube hole 21, but is located on the upper surface of the first plate 2. A holding space for holding the tube body 11 is formed at a position below the first plate 2 corresponding to the test tube hole 21.

[0040] The upper surface of the first plate 2 is provided with an upwardly protruding tube cover limiting component 5, which is used to keep the tube cover 12 in the open position. Specifically, the tube cover limiting component 5 may include a tube cover limiting groove 53 described later, and the tube cover 12 may be accommodated in the tube cover limiting groove 53, thereby being kept in the open position.

[0041] like Figure 2 As shown, when the tube body 11 of the flip-top test tube 1 is installed in the test tube hole 21 and the tube cover 12 is held in the open position by the tube cover limiting component 5, the tube body 11 is tilted as a whole, that is, the axis of the tube body 11 forms an angle with the vertical direction.

[0042] The directions in this embodiment are defined as follows: Figure 2 The first side is closer to the right side, and the second side is closer to the left side. Figure 2 In the embodiment, the tube cover limiting component 5 is located on the first side of the test tube hole 21, and the upper end of the tube body 11 is closer to the second side than the lower end of the tube body 11, that is, the inclined state of the tube body 11 is formed by rotating counterclockwise from the vertical state.

[0043] In order to solve the above-mentioned problem of the tube body 11 being tilted, this embodiment provides a test tube holder having a vertical limiting surface.

[0044] Figure 3 A schematic diagram of a test tube support with a vertical limiting surface provided in this embodiment is shown. Figure 4 A side view of a test tube holder with a vertical limiting surface provided in this embodiment is shown.

[0045] like Figure 3 and Figure 4As shown, the test tube holder also includes a vertical limiting surface 6, which is located below the first plate 2 and at least on the edge of the first side of the test tube hole 21. It can be understood that when the tube body 11 is installed in the test tube hole 21 and the tube cover 12 is maintained in the open position by the tube cover limiting component 5, the side wall of the tube body 11 close to the first side abuts against the vertical limiting surface 6, thereby being restricted by the vertical limiting surface 6, so that the tube body 11 is in a vertical state.

[0046] In this embodiment, the vertical state means that the angle between the axial direction of the tube body 11 and the vertical direction does not exceed 3°.

[0047] Figure 5 A schematic diagram of the lower portion of a test tube holder having a vertical limiting surface provided in an embodiment of the present disclosure is shown. Figure 6 Shows Figure 5 A partial enlarged view of point A in the middle.

[0048] like Figure 5 and Figure 6 As shown, the test tube holder further includes a first stopper 61, which is connected to the lower surface of the first plate 2 and is located at the edge of the first side of the test tube hole 21. The first stopper 61 has a first stopper surface 611 extending vertically, and the vertical stopper surface 6 includes the first stopper surface 611. When the tube body 11 is installed in the test tube hole 21 and the tube cover 12 is held in the open position by the tube cover stopper component 5, the side wall of the tube body 11 close to the first side abuts against the first stopper surface 611, and is thus restricted by the first stopper surface 611, so that the tube body 11 is in a vertical state.

[0049] like Figure 5 and Figure 6 As shown, further, the bottom of the first limiting surface 611 has a rounded corner. Compared with the case where the bottom of the first limiting surface 611 is a right angle, the rounded corner ensures that the side wall of the tube body 11 will not be damaged during the process of inserting the tube body 11 into the test tube hole 21 and taking it out from the test tube hole 21, and the rounded corner can also provide guidance for the movement of the tube body 11, which is conducive to the realization of the taking and placing action.

[0050] like Figure 5 and Figure 6As shown, further, the test tube holder also includes a second limit block 62, which is connected to the lower surface of the first plate 2 and is located at the edge of the second side of the test tube hole 21, the second side is arranged opposite to the first side, and the second limit block 62 has a second limit surface 621 extending vertically, and the vertical limit surface 6 also includes a second limit surface 621. When the tube body 11 is installed in the test tube hole 21 and the tube cover 12 is kept in the open position by the tube cover limit component 5, the side wall of the tube body 11 close to the first side abuts against the first limit surface 611, and the side wall of the tube body 11 close to the second side abuts against the second limit surface 621, so that the tube body 11 is limited by the first limit surface 611 and the second limit surface 621, so that the tube body 11 is in a vertical state.

[0051] like Figure 5 and Figure 6 As shown, further, the bottom of the second limiting surface 621 has a rounded corner. Compared with the case where the bottom of the first limiting surface 611 is a right angle, the rounded corner ensures that the side wall of the tube body 11 will not be damaged during the process of inserting the tube body 11 into the test tube hole 21 and taking it out from the test tube hole 21, and the rounded corner can also provide guidance for the movement of the tube body 11, which is conducive to the realization of the pick-up and placement action. In particular, when the bottom of the first limiting surface 611 and the bottom of the second limiting surface 621 both have rounded corners, the pick-up and placement action of the tube body 11 will become easier, and the side wall of the tube body 11 will be better protected.

[0052] In addition, the lengths of the first limiting surface 611 and the second limiting surface 621 may be greater than 10 mm, such as 15 mm, so as to ensure that the tube body 11 is well limited and remains in a vertical state in the test tube hole 21 .

[0053] In addition, the first limiting block 61 and the second limiting block 62 may also be connected to the supporting plate 4 on the corresponding side to improve the stability of the first limiting block 61 and the second limiting block 62 .

[0054] like Figure 5 and Figure 6 As shown, further, the test tube holder also includes a third limit block 63 and a fourth limit block 64, the third limit block 63 is connected to the lower surface of the first plate 2 and is located at the edge of the third side of the test tube hole 21, the third limit block 63 has a vertically extending third limit surface 631, and the vertical limit surface 6 also includes the third limit surface 631; the fourth limit block 64 is connected to the lower surface of the first plate 2 and is located at the edge of the fourth side of the test tube hole 21, the fourth limit block 64 has a vertically extending fourth limit surface 641, and the vertical limit surface 6 also includes the fourth limit surface 641.

[0055] By providing the third limiting block 63 and the fourth limiting block 64 , the posture of the tube body 11 in the test tube hole 21 can be further limited so that the tube body 11 is in a vertical state.

[0056] In addition, if Figure 6 As shown, the length of the third limiting surface 631 is less than the first limiting surface 611 or the second limiting surface 621, and the length of the fourth limiting surface 641 is less than the first limiting surface 611 or the second limiting surface 621. For example, the length of the third limiting surface 631 is less than 5 mm, and the length of the fourth limiting surface 641 is less than 5 mm.

[0057] In the present embodiment, the first limit block 61, the second limit block 62, the third limit block 63 and the fourth limit block 64 are all relatively independent structures and are not directly connected to each other. However, in an embodiment not shown, the first limit block 61, the second limit block 62, the third limit block 63 and the fourth limit block 64 can be connected to each other, for example, in a circumferential direction around the test tube hole 21.

[0058] like Figure 4 As shown, the tube cover limiting component 5 includes a first stop surface 51 and a second stop surface 52. The second stop surface 52 is closer to the test tube hole 21 than the first stop surface 51. A tube cover limiting groove 53 is formed between the second stop surface 52 and the first stop surface 51. The second side of the tube cover limiting groove 53 has a connecting port 56 (see Figure 3 ), the connection port 56 is configured to accommodate the connection member 13, so that the connection member partially passes through the connection port 56 and enters the tube cover limiting groove 53. In addition, the width of the connection port 56 matches the width of the connection member 13, so that when the connection member 13 is accommodated in the connection port 56, the position of the connection member 13 is basically fixed, ensuring that the tube body 11 cannot rotate around its own axis direction.

[0059] Therefore, when the tube cover 12 is connected in the tube cover limiting component 5, the first side of the tube cover 12 abuts against the first stop surface 51, and the second side of the tube cover 12 abuts against the second stop surface 52, so that the tube cover 12 is restricted in the tube cover limiting groove 53, and the connecting member 13 is accommodated in the connecting port 56.

[0060] like Figure 3 and Figure 4 As shown, the pipe cover limiting component 5 also includes a first column 54 and a second column 55. The first column 54 is fixedly mounted on the upper surface of the first plate 2, and the first stop surface 51 is the surface of the first column 54 facing the second side. The second column 55 is fixedly mounted on the upper surface of the first plate 2, and the second column 55 is closer to the second side than the first column 54, and the second stop surface 52 is the surface of the second column 55 facing the first side.

[0061] like Figure 3As shown, in this embodiment, the number of the first column 54 is one, and the number of the second column 55 is two, but it is not limited thereto. The number of the first column 54 and the number of the second column 55 can be adjusted as needed, for example, the number of the first column 54 is two, and the number of the second column 55 is one. For another example, the number of the first column 54 and the number of the second column 55 are both two.

[0062] In this embodiment, the second columns 55 are staggered with the first columns 54, that is, the connecting direction of the second columns 55 and the first columns 54 forms an angle with the connecting direction of the first side and the second side, thereby forming a connection port 56 between the two second columns 55. However, in other embodiments not shown, especially when the number of the first columns 54 and the number of the second columns 55 are both two, the first columns 54 and the second columns 55 can be aligned with each other.

[0063] like Figure 3 As shown, the first plate 2 also includes a first indicator mark 22 indicating the direction of the test tube holder, and the first indicator mark 22 may be an arrow 221. For example, the arrow 221 is directed toward the second side, indicating that the second side of the first plate 2 is the starting position. The first indicator mark 22 may be located on the upper surface of the first plate 2 or on the side of the first plate 2.

[0064] In addition, if Figure 3 As shown, the first indicator mark 22 can also be a hole 222 located on the first outer support plate 41, while there is no hole on the second outer support plate 42 opposite to the first outer support plate 41, so the orientation of the test tube holder can be distinguished by the position of the hole 222.

[0065] like Figure 3 As shown, the first plate 2 also includes a second indicator mark 23 indicating the position of the test tube hole 21. The second indicator mark 23 can be a number and / or a letter. Each test tube hole 21 corresponds to a second indicator mark 23. For example, the first test tube hole 21 corresponds to the number 1, the second test tube hole 21 corresponds to the number 2, and so on.

[0066] like Figure 5 As shown, the second plate 3 is provided with a through hole 31 corresponding to the test tube hole 21, and the through hole 31 passes through the upper surface and the lower surface of the second plate 3. The through hole 31 is configured to accommodate a lifting component (not shown). When the lifting component enters the through hole 31 from bottom to top, the lifting component pushes the tube body 11 upward, so that a gap is formed between the top of the tube body 11 and the upper surface of the first plate 2, which is convenient for the operator to take the tube body 11 out of the test tube hole 21. The lifting component can be any component that can pass through the through hole 31, such as a boss. In addition, the through hole 31 can also be used to position the test tube holder. For example, when there are bosses in at least two through holes 31, the test tube holder is positioned and cannot move laterally.

[0067] like Figure 5 As shown, a magnet 32 ​​is also provided on the second plate 3, and the magnet 32 ​​is configured to fix the test tube holder on the magnetic base (not shown), so that when the test tube holder is placed on the magnetic base, the test tube holder is fixed on the magnetic base as a whole and will not move easily. The position and number of the magnet 32 ​​can be set as needed, and this embodiment does not limit this.

[0068] Figure 7 A schematic diagram showing a flip-top test tube installed on a test tube holder with a vertical limiting surface provided in this embodiment is shown. Figure 8 A side view of a flip-top test tube installed on a test tube holder with a vertical limiting surface provided in this embodiment is shown.

[0069] like Figure 7 and Figure 8 As shown, when the tube body 11 is installed in the test tube hole 21 and the tube cover 12 is held in the open position by the tube cover limiting component 5, the first side and the second side of the tube body 11 are respectively limited by the first limiting surface 611 and the second limiting surface 621, thereby maintaining a vertical state.

[0070] The above is a description of the embodiments of the present disclosure. Through the above description of the disclosed embodiments, professionals and technicians in the field can implement or use the present disclosure. Various modifications to these embodiments will be apparent to professionals and technicians in the field. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present disclosure. Therefore, the present disclosure will not be limited to the embodiments shown herein, but will conform to the widest range consistent with the principles and novelties disclosed herein.
