Description

Technical Field

[0001] The present application relates to the field of cell culture, and particularly to a tray structure, a shaker, and a cell culture incubator having the shaker. Background Art

[0002] Cell culture technology is an important part of biotechnology and plays an inestimable role in life science research. Currently, in the process of small-scale cell suspension culture, the cell suspension is placed into a shaking flask, and then cultured by shaking using a shaker, so that nutrients can be evenly contacted with the cells.

[0003] The existing shaker incubator includes a box body, and a shaker is arranged inside the box body. The shaker shakes continuously in the horizontal direction to realize cell culture, and this culture method has also been widely used in the field of cell culture.

[0004] A plurality of trays for carrying shaking flasks are arranged on the shaker. Referring to Figure 1 , the tray 1 is in the shape of a cylinder with an opening on one side, and the shaking flask is in the shape of a cone. In order to ensure the smooth insertion of the shaking flask and the tray, there is a clearance fit between the two, that is, there is a small clearance. During the shaking process, if there is such a clearance, the shaking flask will have a certain displacement in the tray, and then the cell liquid will shake irregularly, affecting the cell culture effect. Therefore, elastic clamping pieces are arranged on the peripheral side of the tray. Four elastic clamping pieces act on the outer wall of the shaking flask to realize the clamping of the shaking flask, thereby ensuring the relative fixation of the shaking flask and the tray.

[0005] In practice, the space surrounded by the upper ends of the four elastic clamping pieces is smaller than the bottom of the shaking flask. Therefore, when the shaking flask is inserted into the tray, the four elastic clamping pieces expand outward under the abutment of the shaking flask, and the elastic clamping pieces always abut against the outer wall of the shaking flask. When the shaking flask is placed and taken out, it will always contact the elastic clamping pieces. Although the contact position between the elastic clamping pieces and the shaking flask is smoothed, during multiple operations, it will still cause damage to the surface of the shaking flask, and during the shaking process, the abutting force between the shaking flask and the clamping pieces will increase, which will also cause damage to the shaking flask; in addition, the elastic clamping pieces are located on the peripheral side of the shaking flask, occupying the space of the shaker.

[0006] Therefore, although the existing shaker can achieve the cultivation purpose, it will affect the service life of the shaking flask. Therefore, in order to ensure the service life of the shaking flask, it is urgent to provide another positioning and clamping method for the shaking flask. Summary of the Invention

[0007] In order to solve the above problems and ensure the service life of the shaking flask, the present application provides a tray structure, a shaker, and a cell culture incubator having the shaker.

[0008] The tray structure, shaker, and cell culture incubator having the shaker provided by the present application adopt the following technical solutions:

[0009] A tray structure includes a tray, a rotating pin, a first rotating piece, and a second rotating piece. A bottom of an inner sidewall of the tray is recessed inward to form an avoidance groove, and a plurality of the avoidance grooves are arranged along the circumference. The rotating pin is hinged in the avoidance groove through a torsion spring. The first rotating piece and the second rotating piece are both fixed on the rotating pin, and an included angle between the first rotating piece and the second rotating piece is adapted to the shape of a conical flask. A first receiving groove communicating with the avoidance groove is formed on an inner wall of the tray; initially, under the action of the torsion spring, the first rotating piece is located in the first receiving groove, and the second rotating piece is arranged obliquely upward; when the shaking flask is inserted into the tray, the shaking flask contacts the second rotating piece and drives the rotating pin to rotate, and the rotating pin drives the first rotating piece to rotate and fit with the shaking flask.

[0010] By adopting the above technical solution, when the shaking flask is placed into the tray, the top of the shaking flask will first contact the second rotating piece, and then drive the second rotating piece to rotate downward. The second rotating piece drives the first rotating piece to rotate through the rotating pin, and the first rotating piece gradually rotates and fits on the outer wall of the shaking flask. The first rotating piece fixes and positions the shaking flask, thus ensuring the stability of the shaking flask. When the shaking flask is taken out, the second rotating piece will move as the shaking flask rises, synchronously driving the first rotating piece to rotate, and the first rotating piece separates from the outer wall of the shaking flask. That is, during the process of taking out the shaking flask, the first rotating piece will quickly separate from the shaking flask and will not always contact the surface of the shaking flask. And when the shaking flask is inserted into the tray, the first rotating piece will only contact and position it when the shaking flask and the tray are completely inserted. That is, during the insertion and extraction process, the contact with the first rotating piece is less, which can reduce the damage to the surface of the shaking flask and improve the service life of the shaking flask; in addition, the clamping of the shaking flask is transferred to the tray. In the prior art, the clamping piece is arranged outside the tray, which greatly reduces the occupied space on the shaker.

[0011] Preferably, a second receiving groove communicating with the avoidance groove is formed on a bottom wall of the tray, an avoidance opening is formed on the bottom wall of the tray, the length of the second receiving groove is greater than the length of the avoidance opening, a first abutting portion is formed on an upper side of an end of the avoidance opening of the tray, and a second abutting portion is formed on a lower side; when the shaking flask is inserted into the tray, the second rotating piece is located in the second receiving groove; a limiting elastic piece is formed at an end of the second rotating piece.

[0012] By adopting the above technical solution, when the shaking flask is gradually inserted into the carrier plate, the second rotating piece will gradually rotate into the second receiving groove, and the end of the limiting elastic piece will first abut against the first abutting portion of the avoiding opening, and then the limiting elastic piece will gradually bend, that is, the end of the limiting elastic piece will gradually bend upward. After bending upward, it is convenient for the limiting elastic piece to smoothly enter the second receiving groove. When the limiting elastic piece enters the second receiving groove, the limiting elastic piece resets and abuts against the second abutting portion. That is, at this time, through the abutment between the second abutting portion and the limiting elastic piece, the limiting of the second rotating piece can be realized, and further the positioning and clamping effect of the first rotating piece on the shaking flask can be ensured; if the second rotating piece has no limiting of the second abutting portion, that is, only relying on the action of the gravity of the shaking flask to realize the rotation of the second rotating piece, then the clamping and positioning of the first rotating piece on the shaking flask mainly rely on the gravity of the shaking flask itself. If the shaking flask has an upward movement trend during the shaking process, the first rotating piece and the second rotating piece rotate synchronously. Therefore, the downward acting force on the shaking flask is unreliable, that is, only the shaking flask can be limited in the horizontal direction to prevent it from shaking in the carrier plate; and under the abutment between the second abutting portion and the limiting elastic piece, the first rotating piece is limited, so that clamping forces can be generated on the shaking flask in both the horizontal and vertical directions to ensure the stability of the shaking flask.

[0013] Preferably, a sliding port is formed at the port of the carrier plate located at the avoiding opening. A sliding block is slidably connected in the sliding port. A plugging groove is formed on the bottom wall of the sliding port. A plugging rod that is plugged and matched with the plugging groove is formed on the sliding block. A limiting plate is arranged on the plugging rod. A compression spring is sleeved on the plugging rod. One end of the compression spring is connected to the limiting plate, and the other end of the compression spring is connected to the bottom wall of the plugging groove. The first abutting portion and the second abutting portion are formed on the upper and lower sides of the sliding block.

[0014] By adopting the above technical solution, when the second rotating piece rotates downward, the limiting elastic piece first abuts against the upper side of the sliding block, i.e., the first abutting portion. At this time, the sliding block will not slide. When the second rotating piece continues to rotate under the action of the shaking flask, it drives the bending state of the limiting elastic piece to change. At this time, the end of the limiting elastic piece gradually bends upward. At this time, the limiting elastic piece will abut against the sliding block and drive the sliding block to slide. The sliding of the sliding block can avoid the limiting elastic piece from entering the second accommodating groove. When the limiting elastic piece enters the second accommodating groove, the sliding block resets, and the second abutting portion at the bottom of the sliding block abuts against the limiting elastic piece; through the sliding of the sliding block, the limiting elastic piece can be timely avoided from entering the second accommodating groove. If the sliding block does not slide, then when the end of the limiting elastic piece bends upward, a relatively large displacement is required to make the limiting elastic piece completely enter the second accommodating groove, and then under the action of the torsion spring, the limiting elastic piece will reset and abut against the second abutting portion, that is, the rotation angle of the second rotating piece, and the corresponding rotation angle of the first rotating piece will also become larger. When the limiting elastic piece finally abuts against the second abutting portion, the first rotating piece just fits against the outer wall of the shaking flask, that is, the space for the first rotating piece to continue rotating is small and cannot meet the distance for the limiting elastic piece to rotate downward. Therefore, the sliding block is designed, and the movement of the limiting elastic piece is avoided by the sliding of the sliding block, that is, there is no need for the first rotating piece and the second rotating piece to have an additional rotation distance.

[0015] Preferably, a frosted surface is formed on the first abutting portion of the sliding block.

[0016] By adopting the above technical solution, the friction between the first abutting portion and the bottom of the shaking flask is increased through the frosted surface. On the one hand, the stability of the shaking flask in the carrier tray can be further improved. On the other hand, by the action of the shaking flask on the sliding block, the sliding of the sliding block can be prevented. When the limiting elastic piece is located below the sliding block, the torsion spring makes the second rotating piece generate an upward rotating force, that is, the limiting elastic piece will generate a sliding force on the sliding block. However, the limiting elastic piece contacts the sliding block at its end, so the acting force is not large. In order to prevent the sliding block from sliding under the action of the limiting elastic piece, the cooperation of the frosted surface and the shaking flask can solve this problem.

[0017] Preferably, the limiting spring piece is an arc-shaped spring piece, and the limiting spring piece can be bent in both directions and maintain a bent state; in the initial state, the end of the limiting spring piece bends downward, and when the second rotating piece rotates downward, the end of the limiting spring piece contacts the first abutting portion of the avoidance opening and bends, and the end of the limiting spring piece will finally bend upward and enter the second accommodating groove; an installation opening is provided in the middle of the first rotating piece, and the first rotating piece is located in the installation opening and is provided with an abutting spring piece, and the abutting spring piece is composed of a connecting piece, a first bent piece, and a second bent piece connected in sequence. The connecting piece is connected to the first rotating piece, and the first bent piece and the connecting piece are connected by an arc-shaped flexible piece, the first bent piece and the second bent piece are arranged in a hook shape, and the end of the second bent piece away from the first bent piece is a free end, and an abutting pad is arranged at the connection between the first bent piece and the second bent piece; the end of the limiting spring piece is fixedly connected to a connecting rope, and the other end of the connecting rope passes around the rotating pin and is fixedly connected to the free end of the second bent piece.

[0018] By adopting the above technical solution, when the shaking bottle is plugged into the carrier plate, the limiting spring piece abuts against the sliding block, and then the limiting spring piece will gradually stretch to a straight state. At this time, the limiting spring piece will pull the connecting rope and pull the second bent piece through the connecting rope. The second bent piece drives the first bent piece to rotate, and the rotation point and the connection between the first bent piece and the connecting piece make the abutment pad rotate upward, and the abutment pad does not abut against the shaking bottle in this process; then when the bending state of the limiting spring piece changes, that is, the end of the limiting spring piece contracts, the connecting rope loses tension, and the first bent piece and the second bent piece tend to reset, but at this time the abutment pad has already contacted the shaking bottle, that is, the abutment will not reset at this time, that is, the arc-shaped flexible sheet generates a downward rotational force on the abutment pad. The rotational force acts on the shake bottle, thereby improving the clamping stability of the shake bottle; in practice, the first rotating piece and the shake bottle will not fit tightly together. If they fit tightly together, the first rotating piece will generate a large force on the shake bottle, affecting the life of the shake bottle. Therefore, the function of the first rotating piece is mainly to limit the outer contour of the shake bottle from having a large displacement, and to press tightly through the flexibility of the abutment pad, thereby not causing damage to the shake bottle; when taking out the shake bottle, the shake bottle drives the first rotating piece to rotate through the abutment with the abutment pad, and then drives the second rotating piece to rotate, so that the limiting spring sheet bends again and falls out of the second accommodating groove, that is, in this process, the shake bottle does not directly abut against the first rotating piece, that is, it is always flexibly abutted, thereby ensuring the service life of the shake bottle.

[0019] Preferably, the second rotating piece is provided with an abutting convex bump.

[0020] By adopting the above technical solution, since the limiting spring piece is in a bent state, there is a certain height difference between the limiting spring piece and the second rotating piece. By utilizing the abutting convex bump and the bottom of the shaking bottle, it can be ensured that the second rotating piece drives the limiting spring piece to smoothly enter the second accommodating groove.

[0021] Preferably, a guiding portion is formed at the opening of the carrier tray.

[0022] By adopting the above technical solution, the guiding portion facilitates guiding the shaking flask to quickly enter the carrier tray.

[0023] Preferably, the carrier tray is made of plastic.

[0024] A shaker includes the above carrier tray structure.

[0025] A cell culture incubator includes the above shaker.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. By using the first rotating piece and the second rotating piece to rotate with the shaking flask, when the shaking flask is completely inserted into the carrier tray, the first rotating piece just fits against the peripheral side of the carrier tray to limit the shaking flask in the horizontal direction. Moreover, during the insertion process, the first rotating piece will not have excessive contact with the shaking flask. At the same time, when taking out the shaking flask, under the action of the torsion spring, the first rotating piece will gradually open and also will not contact the shaking flask, thereby helping to prevent damage to the shaking flask.

[0028] 2. By the limiting elastic piece abutting against the second abutting portion to limit the position of the second rotating piece, that is, at this time, the position of the first rotating piece can be ensured, thereby ensuring the positioning and clamping effect of the first rotating piece on the shaking flask in the horizontal and vertical directions, and preventing the first rotating piece and the second rotating piece from moving when the shaking flask has a tendency to move upward during the shaking process, affecting the clamping effect.

[0029] 3. Through the arrangement of the sliding block, the movement of the limiting elastic piece is avoided, that is, there is no need for the first rotating piece and the second rotating piece to have an additional rotation distance, thereby avoiding an increase in the abutting force on the shaking flask due to an increase in the moving distance of the first rotating piece.

[0030] 4. When the limiting elastic piece gradually stretches from being bent, the connecting rope drives the abutting pad to rotate upward. At this time, the abutting pad does not contact the shaking flask. When the limiting elastic piece gradually bends from being stretched, the abutting pad rotates downward and then contacts the surface of the shaking flask to realize the clamping and positioning of the shaking flask, and the flexible abutting can prevent damage to the shaking flask.

Detailed implementation manners

[0043] The following further describes the present application in detail with reference to the attached Figure 2 - attached Figure 11 drawings.

[0044] The embodiments of the present application disclose a carrier tray structure.

[0045] Embodiment 1

[0046] Refer to Figure 2 and Figure 3, the tray structure includes a tray 1, a rotating pin 2, a first rotating piece 3 and a second rotating piece 4. A guiding portion 11 is formed at the opening of the tray 1, which facilitates guiding the shaking flask to quickly enter the tray 1. A avoiding groove 12 is formed by inward depression at the bottom of the inner side wall of the tray 1, and a plurality of avoiding grooves 12 are circumferentially distributed in the tray 1, preferably three or four. In this application, four are taken as an example for illustration. The rotating pin 2 is rotatably connected in the avoiding groove 12 through a torsion spring. Both the first rotating piece 3 and the second rotating piece 4 are fixed on the rotating pin 2. The included angle between the first rotating piece 3 and the second rotating piece 4 is an acute angle and is adapted to the shape of the bottom side of the conical flask. A first receiving groove 13 communicating with the avoiding groove 12 is formed on the inner wall of the tray 1, and the first receiving groove 13 and the avoiding groove 12 form an integral groove structure. In the initial state, the first rotating piece 3 is located in the first receiving groove 13, and the second rotating piece 4 is arranged obliquely upward. When the shaking flask is inserted into the tray 1, the shaking flask contacts the second rotating piece 4 and drives the rotating pin 2 to rotate. The rotating pin 2 drives the first rotating piece 3 to rotate and fit with the shaking flask.

[0047] When the shaking flask is placed into the tray 1, the top of the shaking flask will first contact the second rotating piece 4, and then drive the second rotating piece 4 to rotate downward. The second rotating piece 4 drives the first rotating piece 3 to rotate through the rotating pin 2. The first rotating piece 3 gradually rotates and fits on the outer wall of the shaking flask. The first rotating piece 3 fixes and positions the shaking flask, which can ensure the stability of the shaking flask. When the shaking flask is taken out, the second rotating piece 4 will move with the rising of the shaking flask, synchronously driving the first rotating piece 3 to rotate. The first rotating piece 3 separates from the outer wall of the shaking flask. That is, during the process of taking out the shaking flask, the first rotating piece 3 will quickly separate from the shaking flask and will not always contact the surface of the shaking flask. When the shaking flask is inserted into the tray 1, the first rotating piece 3 will only contact and position it when the shaking flask is completely inserted into the tray 1.

[0048] That is, during the insertion and extraction process, the shaking flask and the first rotating piece 3 will quickly separate, and there is no scraping situation, which can ensure the service life of the shaking flask. And during shaking, because the first rotating piece 3 and the outer wall of the shaking flask are in a fitting state, even if a resisting force is generated, it is not a point contact, which can also reduce the damage to the shaking flask. Setting the clamping structure for the shaking flask into the tray 1 greatly reduces the occupied space on the surface of the shaker compared with the prior art.

[0049] For this design, if the elastic clip in the prior art is directly arranged on the inner wall of the carrier 1, the positioning of the shaking flask can also be achieved. However, if it is directly arranged on the inner wall of the carrier 1, the length of the elastic clip will be greatly reduced, and then its deformability will decrease, resulting in an increase in the abutting force with the shaking flask, which will further affect the service life of the shaking flask. In addition, if a more deformable material is used for the elastic clip, due to its small size, the abutting force on the shaking flask becomes smaller, resulting in a decrease in the positioning and clamping effect. Therefore, it is difficult to achieve both by changing the material. Therefore, in this application, the cooperation of the first rotating piece 3 and the second rotating piece 4 is adopted to ensure the positioning and clamping effect, and there will be no large point abutting force with the shaking flask, ensuring the service life of the shaking flask.

[0050] In practice, the carrier 1 is made of plastic material, and the carrier 1 is composed of four sub-carriers. The first accommodating groove 13 and the avoiding groove 12 are formed between adjacent sub-carriers. After the rotating pin 2, the first rotating piece 3 and the second rotating piece 4 are installed, the connection of all sub-carriers can be realized through an adhesive to form the carrier 1.

[0051] Embodiment 2

[0052] Refer to Figure 4 , the difference between this embodiment and Embodiment 1 is that a second accommodating groove 14 communicating with the avoiding groove 12 is formed on the bottom wall of the carrier 1, that is, the first accommodating groove 13, the avoiding groove 12 and the second accommodating groove 14 are in an L-shaped groove. An avoiding opening 5 is formed on the bottom wall of the carrier 1. The length of the second accommodating groove 14 is greater than the length of the avoiding opening 5. A first abutting portion 51 and a second abutting portion 52 are formed at one end of the avoiding opening 5 away from the inner wall of the carrier 1. The first abutting portion 51 is located on the upper side, and the second abutting portion 52 is located on the lower side. A limiting elastic piece 6 is formed at the end of the second rotating piece 4.

[0053] Refer to Figure 5 and Figure 6, when the shaking flask is gradually inserted into the carrier tray 1, the second rotating piece 4 will gradually rotate into the second receiving groove 14, and the end of the limiting elastic piece 6 will first contact the first abutting portion 51 of the avoidance port 5, and then the limiting elastic piece 6 will gradually bend, that is, the end of the limiting elastic piece 6 will gradually bend upward. After bending upward, it is convenient for the limiting elastic piece 6 to smoothly enter the second receiving groove 14. When the limiting elastic piece 6 enters the second receiving groove 14, the limiting elastic piece 6 resets and contacts the second abutting portion 52. That is, at this time, through the contact between the second abutting portion 52 and the limiting elastic piece 6, the limiting of the second rotating piece 4 can be realized, and then the positioning and clamping effect of the first rotating piece 3 on the shaking flask can be ensured; if the second rotating piece 4 has no limit of the second abutting portion 52, that is, only relying on the action of the gravity of the shaking flask to realize the rotation of the second rotating piece 4, then the clamping and positioning of the first rotating piece 3 on the shaking flask also mainly rely on the gravity of the shaking flask itself. If the shaking flask has an upward movement tendency during the shaking process, the first rotating piece 3 and the second rotating piece 4 rotate synchronously, so the downward acting force on the shaking flask is not reliable, that is, only the shaking flask can be limited in the horizontal direction to prevent it from shaking in the carrier tray 1; while under the contact between the second abutting portion 52 and the limiting elastic piece 6, the first rotating piece 3 is limited, and then clamping forces can be generated on the shaking flask in both the horizontal and vertical directions to ensure the stability of the shaking flask.

[0054] Embodiment 3

[0055] Refer to Figure 7 and Figure 8 , the difference between this embodiment and Embodiment 2 is that a sliding port 53 is formed at the port of the carrier tray 1 at the avoidance port 5. The sliding port 53 runs through up and down. A sliding block 7 is slidably connected in the sliding port 53. A plugging groove 531 is formed on the bottom wall of the sliding port 53. A plugging rod 71 that is plugged and matched with the plugging groove 531 is provided on the sliding block 7. A limiting plate 711 is provided on the plugging rod 71, and the limiting plate 711 is located in the plugging groove 531. A compression spring 712 is sleeved on the plugging rod 71. One end of the compression spring 712 is connected to the limiting plate 711, and the other end is connected to the bottom wall of the plugging groove 531. The first abutting portion 51 and the second abutting portion 52 are formed on the upper and lower sides of the sliding block 7.

[0056] When the second rotating piece 4 rotates downward, the limiting elastic piece 6 first contacts the upper side of the sliding block 7, that is, the first abutting portion 51, and at this time the sliding block 7 remains stationary. As the second rotating piece 4 continues to rotate under the drive of the shaking flask, the bending state of the limiting elastic piece 6 changes, and its end gradually bends upward. During this process, the limiting elastic piece 6 contacts the sliding block 7 and pushes the sliding block 7 to slide, so that the sliding block 7 avoids the limiting elastic piece 6 and enables it to smoothly enter the second receiving groove 14. When the limiting elastic piece 6 completely enters the second receiving groove 14, the sliding block 7 resets, and the second abutting portion 52 at its bottom contacts the limiting elastic piece 6.

[0057] By the sliding of the sliding block 7, the limiting elastic piece 6 can timely avoid and enter the second accommodating groove 14. If the sliding block 7 does not slide, the limiting elastic piece 6 needs a larger displacement when bending upward to completely enter the second accommodating groove 14, and then resets under the action of the torsion spring and contacts the second abutting portion 52. This will cause the second rotating piece 4 to require a larger rotation angle, and further increase the rotation angle of the first rotating piece 3. When the limiting elastic piece 6 finally contacts the second abutting portion 52, the first rotating piece 3 has already adhered to the outer wall of the shaking flask, and the space for its continuous rotation is limited, unable to meet the distance required for the downward movement of the limiting elastic piece 6. Therefore, designing the sliding mechanism of the sliding block 7 can effectively avoid the movement of the limiting elastic piece 6 and prevent the first rotating piece 3 and the second rotating piece 4 from requiring additional rotation angles.

[0058] A frosted surface is formed on the first abutting portion 51 of the sliding block 7. Through the frosted surface, the friction force between the sliding block 7 and the shaking flask can be significantly increased. This design not only enhances the stability of the shaking flask in the carrier plate 1, but also effectively prevents the sliding of the sliding block 7 through the reaction force exerted by the shaking flask on the sliding block 7. When the limiting elastic piece 6 is located below the sliding block 7, the action of the torsion spring will generate an upward rotating force on the second rotating piece 4, and then the limiting elastic piece 6 exerts a sliding force on the sliding block 7. However, since the limiting elastic piece 6 only contacts the sliding block 7 through its end portion, the applied force is relatively small. In order to prevent the sliding block 7 from sliding under the action of the limiting elastic piece 6, the cooperative design of the frosted surface and the shaking flask cleverly solves this problem.

[0059] When the sliding block 7 slides and exposes the limiting elastic piece 6 to abut against the shaking flask, the positioning and clamping effect on the shaking flask will fail.

[0060] Embodiment 4

[0061] Referring to Figure 9 , the difference between this embodiment and Embodiment 3 is that the limiting elastic piece 6 is an arc-shaped elastic piece, and the structure of the limiting elastic piece 6 is similar to the structure of a hairpin, that is, the limiting elastic piece 6 can be bent bidirectionally and maintain the bent state. In the initial state, the end portion of the limiting elastic piece 6 bends downward. When the shaking flask drives the second rotating piece 4 to rotate downward, the end portion of the limiting elastic piece 6 abuts against the first abutting portion 51 of the sliding block 7, and then the limiting elastic piece 6 is gradually stretched until its end portion bends upward, and finally enters the second accommodating groove 14.

[0062] Referring to Figure 9 and Figure 10, a mounting opening 31 is provided in the middle of the first rotating piece 3, and an abutting elastic piece 8 is arranged in the mounting opening 31. The abutting elastic piece 8 is composed of a connecting piece 91, a first bent piece 92, and a second bent piece 93 connected in sequence. The connecting piece 91 is fixedly connected to the first rotating piece 3. The first bent piece 92 and the connecting piece 91 are gradually connected by an arc-shaped flexible piece 10. Under the action of the arc-shaped flexible piece 10, the first bent piece 92 can rotate; the connection part between the first bent piece 92 and the second bent piece 93 is hook-shaped, and one end of the second bent piece 93 away from the first bent piece 92 is a free end. An abutting pad 20 is fixedly connected to the connection part between the first bent piece 92 and the second bent piece 93.

[0063] Refer to Figure 9 , Figure 10 and Figure 11 , a support groove 61 is provided in the middle of the limiting elastic piece 6. One end of the support groove 61 of the limiting elastic piece 6 is fixedly connected to a connecting rope 30. The other end of the connecting rope 30 bypasses the rotating pin 2 and is fixedly connected to the free end of the second bent piece 93.

[0064] When the shaking flask is inserted into the carrier plate 1, the limiting elastic piece 6 first contacts the sliding block 7, and then the limiting elastic piece 6 is gradually stretched to a straight state. During this process, the limiting elastic piece 6 pulls the connecting rope 30, and the connecting rope 30 further pulls the second bent piece 93. The second bent piece 93 drives the first bent piece 92 to rotate around the arc-shaped flexible piece 10, so that the abutting pad 20 rotates upward. At this stage, the abutting pad 20 has not yet contacted the shaking flask.

[0065] When the bending state of the limiting elastic piece 6 changes (that is, its end contracts), due to the existence of the support groove 61, part of the connecting rope 30 will enter the support groove 61. At this time, the connecting rope 30 loses a certain amount of tension, and the first bent piece 92 and the second bent piece 93 tend to reset. However, at this time, the abutting pad 20 has already contacted the shaking flask, so the reset is blocked. The arc-shaped flexible piece 10 exerts a downward rotational force on the abutting pad 20, and this force is transmitted to the shaking flask, thereby enhancing the clamping stability of the shaking flask.

[0066] In practical applications, there is no close fit between the first rotating piece 3 and the shaking flask. If there is a close fit, the first rotating piece 3 will exert too much force on the shaking flask, affecting the service life of the shaking flask. Therefore, the main function of the first rotating piece 3 is to limit the large displacement of the outer contour of the shaking flask, and through the flexible abutment of the abutting pad 20, damage to the shaking flask is avoided.

[0067] When the shaking flask is taken out, the shaking flask drives the first rotating piece 3 to rotate through the contact with the abutting pad 20, and then drives the second rotating piece 4 to rotate, so that the limiting elastic piece 6 bends again and disengages from the second receiving groove 14. During this process, the shaking flask always contacts the abutting pad 20 through flexible abutment, avoiding direct rigid contact with the first rotating piece 3, thereby ensuring the service life of the shaking flask.

[0068] An abutting convex bump 41 is integrally formed on the second rotating piece 4. Since the limiting elastic piece 6 is in a bent state, there is a certain height difference between the limiting elastic piece 6 and the second rotating piece 4. By using the abutting convex bump 41 to cooperate with the bottom of the shaking flask, it can be ensured that the second rotating piece 4 drives the limiting elastic piece 6 to smoothly enter the second accommodating groove 14, preventing the second rotating piece 4 from completely entering the second accommodating groove 14 while the shaking flask cannot drive the second rotating piece 4 to descend again, thereby causing the limiting elastic piece 6 to be unable to enter the second accommodating groove 14.

[0069] The embodiment of the present application also discloses a shaker, which includes the carrier plate 1 described in any of the above embodiments, and a plurality of carrier plates 1 are arranged in an array on the shaker.

[0070] The embodiment of the present application also discloses an incubator, which includes the above-mentioned shaker.

[0071] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
