Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and in particular to a collection tube holder. Background Technology

[0002] In biological and chemical experiments, collection tubes are a commonly used piece of equipment. There are two most common structures for collection tubes: one is the screw-cap type, where the tube body and cap are sealed by a threaded connection; the other is the integrated cap type, where the tube body and cap are integrally connected by a flexible material, and the cap is pressed against the tube opening to achieve a seal. Collection tube holders are devices used to orderly hold collection tubes. They typically have several rectangular arrays of placement holes on the holder, into which the collection tubes are placed. For integrated cap collection tubes, the cap naturally opens at an upward angle when open. The cap of one collection tube may obstruct the view of an adjacent collection tube, causing liquid to drip onto the cap or even completely block the tube opening during pipetting.

[0003] Furthermore, traditional tube holders require a placement slot with a diameter slightly larger than the tube's diameter to facilitate placement and removal. However, in some automated analyses, movable worktables are often used in conjunction with the instrument. The tube holder is fixed to the worktable and moves to the designated test position. Excessive gap between the tube and the placement slot can cause the tube to wobble during movement, negatively impacting liquid injection during pipetting. Therefore, in automated analyses, it is crucial that the tube holder maintains the tube in a predetermined position and orientation so that the instrument can accurately pipette it. Utility Model Content

[0004] The purpose of this invention is to solve the problem that traditional test tube racks cannot simultaneously satisfy the requirements of preventing test tubes from shaking and making them easy to pick up and put down. This invention provides a test tube holder that has the advantages of fixing test tubes with a cap, preventing them from shaking, and making them easy to pick up and put down.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A collection tube holder includes a frame body, a first placement groove for placing a first collection tube is provided on the top of the frame body, a slot is provided on one side of the frame body, a cap for the first collection tube is movably engaged in the slot, the cap is connected to the first collection tube, the cap includes a cover plate and a retaining ring disposed on the cover plate, the slot includes a first slot, and the retaining ring is inserted into the first slot.

[0007] Preferably, the cap further includes a flange portion, which is disposed at the edge of the opening of the first collecting tube, and the flange portion is connected to the cover plate by a connecting strip.

[0008] Preferably, the connecting strip is a flexible structure.

[0009] Preferably, the slot further includes a second slot for the cover plate to be inserted into the second slot when the retaining ring is inserted into the first slot.

[0010] Preferably, a second sidewall and a first sidewall are sequentially arranged on one side of the frame in a direction away from the frame, a first slot is provided on the first sidewall, and the gap between the first sidewall and the second sidewall forms the second slot.

[0011] Preferably, the top of the frame is provided with a first top surface and a second top surface, which divide the opening of the first placement slot into two parts. The top height of the first top surface is lower than the top height of the second top surface, so that when the first collection tube is placed in the first placement slot, there is a gap between the flange and the first top surface.

[0012] Preferably, a second placement slot is also installed at one end of the frame, and a second collection tube is placed inside the second placement slot. The second collection tube has a different capacity than the first collection tube.

[0013] Preferably, both the first and second placement slots have observation windows on their side walls that allow observation of the test tubes inside.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By connecting a cap to the first collection tube, after the first collection tube is placed in the first placement slot, the cap engages with the slot on the frame, enhancing the tightness of the connection between the first collection tube and the first placement slot. This prevents the first collection tube from colliding in the first placement slot when the frame shakes. The snap ring's toughness enables the snap ring to engage with the slot, making the operation convenient and quick. The snap ring also has a certain degree of toughness, ensuring a tight connection with the slot and preventing fatigue and shaking even after prolonged use.

[0016] 2. The first and second top surfaces of the frame of this utility model are not at the same height. When the first collection tube is placed in the first placement slot, there is a gap between the top and the lower first top surface, which makes it convenient to take out the first collection tube.

[0017] 3. A second placement slot is also provided on the frame, which can accommodate test tubes of different sizes by using the first and second placement slots, and an observation window is opened on the side wall to observe information such as the color and volume of the liquid in the test tube.

Detailed Implementation

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1 and Figure 2As shown, a collection tube holder is disclosed, including a frame body 1. The top of the frame body 1 is provided with a first placement slot 2 for placing a first collection tube 4. A slot 7 is provided on one side of the frame body 1, in which a cap 6 of the first collection tube 4 is movably engaged. The cap 6 is connected to the first collection tube 4. The cap 6 includes a cover plate 15 and a retaining ring 16 disposed on the cover plate 15. The slot 7 includes a first slot 11, in which the retaining ring 16 is inserted. Multiple first placement slots 2 can be provided on the frame body 1, arranged in a straight line and adapted according to the usage. The first placement slots 2 are adapted to the first collection tube 4. To facilitate the placement and removal of the first collection tube 4, the opening size of the first placement slot 2 is slightly larger than the diameter of the first collection tube 4. However, in some equipment and instruments, the frame body 1 is moved using automated components. In this usage environment, because the dimensions of the first collection tube 4 and the first placement slot 2 do not perfectly match, gaps exist, causing collisions between the tube wall and the slot wall during movement. To solve this defect, such as... Figure 2 As shown, by using the cap 6 installed on the first collection pipe 4 and the slot 7 on the frame 1 to fix it, the relative displacement between the first collection pipe 4 and the first placement slot 2 is avoided, thereby preventing the occurrence of collision.

[0028] The engagement between the cap 6 and the slot 7 can utilize various engagement structures. Here, the cap 6 includes a retaining ring 16. The retaining ring 16 engages with the first slot 11, achieving a superior engagement effect compared to some existing plug-in or snap-fit ​​structures. This is because the retaining ring 16 is a closed ring structure with a certain degree of flexibility on its sides. This flexibility allows the retaining ring 16 to engage more tightly when inserted into the first slot 11, and this flexibility remains even after prolonged use. Compared to rigid snap-fits or plug-ins, it is less prone to deformation and has a longer service life. Figure 3 As shown, the first slot 11 is located on the top of the first side wall 17 and has an arc-shaped structure. The arc-shaped first slot 11 can fit with the retaining ring 16 to firmly fix the retaining ring 16. The first slot 11 can also provide an upward support effect for the retaining ring 16. When the connecting strip 14 is a flexible structure, the end of the connecting strip 14 connected to the retaining ring 16 is subjected to an upward support force, while the end connected to the first collection tube 4 is subjected to a downward pressure, which makes the tube better inserted into the first placement groove 2, thereby further maintaining the first collection tube 4 in the predetermined position and posture.

[0029] like Figure 5As shown, the cap 6 also includes a flange 13, which is located at the edge of the opening of the first collecting tube 4. The flange 13 is connected to the cover plate 15 via a connecting strip 14. The flange 13, being located at the edge of the opening of the first collecting tube 4, does not obstruct the opening. Furthermore, the outer diameter of the flange 13 is larger than the inner diameter of the opening of the first placement groove 2, preventing the first collecting tube 4 from falling into the bottom of the first placement groove 2, thus providing a certain degree of restraint. The connecting strip 14 is a flexible structure. The flexible structure of the connecting strip facilitates the movement of the cover plate 15, making it easier for the retaining ring 16 to engage with the first slot 11 and for the cover plate 15 to cover the opening of the first collecting tube 4.

[0030] To ensure the secure connection of the 6-pin clip, such as Figure 6 As shown, the retaining ring 16 is disposed on the cover plate 15, and the retaining groove 7 also includes a second slot 12, which is used for the cover plate 15 to be inserted into the second slot 12 when the retaining ring 16 is inserted into the first slot 11. The use of the second slot 12 and the first slot 11 to engage with the cover plate 15 and the retaining ring 16 together is more secure and has a higher fault tolerance rate than a single engagement.

[0031] like Figure 4 As shown, a second sidewall 18 and a first sidewall 17 are sequentially arranged on one side of the frame 1, facing away from the frame 1. A first slot 11 is disposed on the first sidewall 17. The gap between the first sidewall 17 and the second sidewall 18 forms the second slot 12. The cooperation between the first slot 11 and the second slot 12 improves the stability of the first collecting tube 4. Figure 4 As shown, the first sidewall 17 is closer to the outer side than the second sidewall 18 relative to the frame 1. The gap between them forms the second slot 12. When the first collection tube 4 is installed in the first placement slot 2, the cover plate 15 is rotated in the opening direction after the tube is inserted, and the cover plate 15 is inserted into the second slot 12. At this time, the inner surface of the cover plate 15 faces the inner surface of the first sidewall 17, and the outer surface of the cover plate 15 faces the outer surface of the second sidewall 18. The cover plate 15 is confined between the two, which prevents shaking. This design can fix the cover plate 15 in a position that does not obstruct the opening of the tube. Moreover, when the connecting strip 14 has a spring force on the cover plate 15 in the closing direction, the contact between the cover plate 15 and the first sidewall 17 can prevent the cover plate 15 from moving in the closing direction.

[0032] like Figure 7As shown, the top of the frame 1 is provided with a first top surface 8 and a second top surface 9. The first top surface 8 and the second top surface 9 divide the opening of the first placement slot 2 into two parts. The top height of the first top surface 8 is lower than the top height of the second top surface 9, so that when the first collection tube 4 is placed in the first placement slot 2, there will be a gap between the flange 13 at the top of the first collection tube 4 and the first top surface 8. The first top surface 8 and the second top surface 9 form a stepped structure, so that when the first collection tube 4 is fully inserted into the first placement slot 2, the top flange 13 will only contact the second top surface 9, which is the highest. This creates a gap between the first top surface 8 and the flange 13 of the first collection tube 4, preventing the first collection tube 4 from fitting tightly into the opening of the first placement slot 2 and affecting its removal. Moreover, the first top surface 8 is located on the side away from the cap 6, preventing the presence of the cap 6 in the slot 7 state from affecting the operator's access to the gap between the first top surface 8 and the flange 13 of the first collection tube 4.

[0033] like Figure 1 and Figure 2 As shown, a second placement slot 3 is installed at one end of the frame 1. A second collection tube 5 is placed inside the second placement slot 3. The second collection tube 5 has a different capacity than the first collection tube 4. Using two different sizes of placement slots increases the versatility of test tube placement. Of course, the frame 1 is not limited to only two sizes of placement slots; various numbers of placement slots can be selected according to needs. A locking structure of caps 6 and slots 7 can be selectively provided to accommodate different test tubes. Both the first placement slot 2 and the second placement slot 3 have observation windows 10 on their side walls, allowing observation of the liquid level and color within the collection tubes.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
