Description

Technical Field

[0001] This utility model relates to the field of test tube rack technology, and in particular to a test tube rack for cell culture. Background Technology

[0002] Cell culture refers to a method of enabling cells to survive, grow, reproduce, and maintain their main structures and functions in vitro by simulating the in vivo environment (sterile, suitable temperature, pH, and certain nutritional conditions, etc.). Cell culture is also called cell cloning technology, and the formal term in biology is cell culture technology.

[0003] When performing cell culture, the collected cells need to be placed in test tubes. However, the bottom of conventional test tubes is mostly curved, which makes it impossible to place them directly on a table or support surface. Therefore, test tube racks are needed to hold the test tubes. Existing test tube racks are mostly simple frame structures with slots for placing test tubes. After the test tubes are placed in the slots, the top edge of the test tube rests on the test tube rack. This means that when removing the test tubes, it is necessary to manually reach under the test tube rack and push the test tubes upwards. This operation is time-consuming and laborious. Moreover, the space under the test tube rack is limited, especially for test tube racks with multiple rows, making it even more troublesome to remove the test tubes.

[0004] Therefore, a test tube rack for cell culture is proposed. Utility Model Content

[0005] The purpose of this invention is to address the inconvenience of removing test tubes from test tube racks in existing technologies, and to propose a test tube rack for cell culture.

[0006] In view of this, the present invention provides a test tube rack for cell culture, including a support base, support plates on both sides above the support base, the support plates being arranged in a stepped manner, and the bottom of the support plates being fixed to the support base by support legs, and the adjacent support plates being fixed by a connecting frame.

[0007] The support plate has several slots arranged at intervals along its length. Below each slot is a strip-shaped push plate. A connecting shaft is located below the end of the push plate away from the slot. The end of the connecting shaft is fixed to the support leg, and a rotating seat is rotatably mounted on the connecting shaft. The rotating seat is fixed to the push plate.

[0008] Preferably, the connecting shaft is also equipped with several fixed seats, each corresponding to a push plate. The side of each fixed seat is provided with a torsion spring, which is sleeved on the connecting shaft. One end of the torsion spring is fixed to the fixed seat, and the other end of the torsion spring is fixed to the rotating seat.

[0009] Preferably, a limiting plate is installed on the side of the fixing seat near the slot, and the top of the limiting plate corresponds to the bottom surface of the push plate.

[0010] Preferably, a lever is installed at the end of the push plate away from the groove, the end of the lever away from the push plate is bent upward, and multiple anti-slip strips are installed on the inner side of the lever.

[0011] Preferably, a top block is installed on the top of the push plate near the slot, the top block being an elastic rubber block, and the top block being arranged along the length direction of the push plate.

[0012] Preferably, an annular plate is provided in the slot, and multiple spring pieces with their ends bent into an L-shape facing the annular plate are provided in the annular plate. The multiple spring pieces are arranged at intervals, and the ends of the spring pieces are fixed to the inner wall of the annular plate.

[0013] Preferably, the corners of the spring pieces are all arc-shaped surfaces, and rough-surfaced buffer pads are installed on the outer walls of the spring pieces. The buffer pads are rubber pads.

[0014] Compared with the prior art, this utility model provides a test tube rack for cell culture, which has the following beneficial effects:

[0015] 1. This utility model, by rotating the push plate below the slot, can push the test tube upward from the slot, so that the test tube is fully exposed above the slot, making it easy for the operator to directly pinch the exposed part of the tube and pull out the test tube, so that the removal of the test tube is not affected by the narrow space below the support plate.

[0016] 2. This utility model, through the staggered, stepped arrangement of support plates, ensures that the rows of test tubes are not interfered with by the field of vision. That is, when the operator observes the test tubes in the test tube rack, the object being observed will not be affected by the objects in the test tubes behind, thus improving the operator's observation effect on the objects in the test tubes.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Please see Figures 1 to 4 A test tube rack for cell culture includes a support base 3. In actual use, the support base 3 is a rectangular frame, and anti-slip pads are installed at the bottom of the support base 3 to increase the friction between the support base 3 and the table or placement surface, thereby enhancing the stability of the support base 3 when it is placed.

[0025] like Figure 1 and Figure 3 As shown, support plates 1 are provided on both sides above the support base 3. The support plates 1 are arranged in a stepped manner, and the bottom of the support plate 1 is fixed to the support base 3 by support legs 2. Adjacent support plates 1 are fixed by connecting brackets 4, providing multi-position support for the support plates 1 on the support base 3, so that the support plates 1 are stable on the support base 3. Among them, several slots 5 are opened along the length of the support plate 1 at intervals, which can support multiple test tubes (such as...) on the support plate 1. Figure 1 Place the test tubes at the location indicated by the middle arrow A, and use the stepped support plate 1 to stagger the heights of the two rows of test tubes. That is, the bottoms of the two rows of test tubes are staggered. In actual use, since the culture medium for cell culture needs to be used in appropriate amounts, it is only concentrated in a part of the bottom space of the test tubes. In this way, when looking at the test tubes from one side, the two rows of test tubes will not affect each other, which provides convenience for the observation of cell culture.

[0026] It should be noted that, as Figure 1As shown, an annular plate 6 is provided within the slot 5. In actual use, the length of the annular plate 6 is greater than the depth of the slot 5, allowing the annular plate 6 to cover more of the test tube when it is placed inside. Multiple L-shaped spring pieces 7, with their ends bent towards the annular plate 6, are provided within the annular plate 6. These spring pieces 7 are spaced apart, and their ends are fixed to the inner wall of the annular plate 6. When the test tube is placed inside the annular plate 6, the volume of the test tube compresses the spring pieces 7, causing them to generate an elastic reaction force on the test tube, thereby improving the stability of the test tube within the annular plate 6. The ends of the spring pieces 7 correspond to the ends of the annular plate 6, and combined with the length of the annular plate 6, this increases the surface area of ​​the spring pieces 7 on the test tube, strengthening the stability of the test tube within the annular plate 6.

[0027] Furthermore, when the test tube is placed into the annular plate 6, it will first contact the corner of the spring piece 7. In order to make the test tube slide smoothly and effortlessly, the corner of the spring piece 7 is an arc surface 8. At the same time, since the test tubes are mostly thin-walled glass tubes, rough-surfaced buffer pads 9 are installed on the outer wall of the spring piece 7. The buffer pads 9 are rubber pads, which provide cushioning for the spring piece 7 to squeeze the test tube. Moreover, the rough surface of the buffer pads 9 also increases the friction after the buffer pads 9 come into contact with the test tube, ensuring the test tube is fixed in the annular plate 6.

[0028] When it is necessary to remove the test tube from the ring plate 6, such as Figure 1 and Figure 2 As shown, a strip-shaped push plate 10 is provided below each slot 5. A connecting shaft 12 is provided below the end of the push plate 10 that is far away from the slot 5. The end of the connecting shaft 12 is fixed to the support leg 2, and a rotating seat 11 is rotatably mounted on the connecting shaft 12. The rotating seat 11 is fixed to the push plate 10, so that the push plate 10 can rotate with the connecting shaft 12 as the axis.

[0029] Specifically, when retrieving a test tube, the operator first uses one hand to hold down the support plate 1 to stabilize the entire test tube rack. Then, using the fingers of the other hand, the operator places them on the push plate 10 below the test tube to be retrieved and presses down on the end of the push plate 10, causing the end of the push plate 10 closest to the test tube to deflect upwards. To allow the fingers to better fit the push plate 10, a lever 17 is installed at the end of the push plate 10 furthest from the groove 5. The end of the lever 17 furthest from the push plate 10 is bent upwards. The device is equipped with multiple anti-slip strips 18 spaced apart on the inner side of the push plate 17 to prevent fingers from slipping off the push plate 10 when it is pressed. The push plate 10 will push the test tube out of the ring plate 6 and protrude a section from the support plate 1. At this time, the operator can remove his / her hand from the push plate 10 and pinch the part of the test tube that protrudes from the support plate 1 to remove the test tube from the ring plate 6. This is more labor-saving and convenient than reaching under the support plate 1 to push the test tube out.

[0030] It should be noted that, as Figure 2 and Figure 4 As shown, several fixed seats 13 are also installed on the connecting shaft 12. Each fixed seat 13 corresponds to a push plate 10. A torsion spring 14 is provided on the side of the fixed seat 13. The torsion spring 14 is sleeved on the connecting shaft 12. One end of the torsion spring 14 is fixed to the fixed seat 13, and the other end of the torsion spring 14 is fixed to the rotating seat 11. After the push plate 10 deflects upward, the torsion spring 14 will deform due to the deflection of the push plate 10 and provide a reverse elastic force to the push plate 10. This allows the push plate 10 to return to its initial position after the external force is removed, so as not to affect the excessive rotation of the push plate 10 and affect the subsequent placement of test tubes and its own use. At the same time, it also provides elastic support for the push plate 10 on the connecting shaft 12. That is, when there is no external force, the push plate 10 is always located above the support seat 3, so as to prevent the push plate 10 from deflecting downward and falling due to its own center of gravity and gravity when moving the test tube rack, which would cause inconvenience to the subsequent repositioning of the test tube rack.

[0031] Furthermore, in order to cooperate with the torsion spring 14 to provide stable support for the push plate 10 on the connecting shaft 12, a limiting plate 15 is installed on the side of the fixed seat 13 near the slot 5. The top of the limiting plate 15 corresponds to the bottom surface of the push plate 10, providing rigid support for the push plate 10 to ensure that the position of the push plate 10 is stable without external force.

[0032] It should be noted that, in order to avoid the test tube being damaged due to excessive impact caused by the sudden upward deflection of the push plate 10 when it comes into contact with the test tube, a top block 16 is installed on the top of the end of the push plate 10 near the slot 5. The top block 16 is an elastic rubber block and is set along the length of the push plate 10, which can provide cushioning when the push plate 10 comes into contact with the test tube.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
