Description

Technical Field

[0001] This application relates to the field of culture bag fixing devices, and in particular to a knob-type culture bag fixing device. Background Technology

[0002] Commonly used wave-type bioreactors employ a non-contact cell culture method and are used in conjunction with disposable cell culture bags. A wave-type bioreactor utilizes the oscillating motion of a shaker to create a wave-like liquid surface movement within a disposable, sterile culture bag, thus providing gentle and efficient mixing and oxygen transfer for cell culture. The wave-type bioreactor uses clamps to secure the disposable cell culture bag to the equipment, causing the bag to oscillate for cell culture. Currently, the industry standard is to use bolt-locked clamps, placing the fixing rods on both sides of the cell culture bag between two clamps, and then tightening the clamps to firmly secure the culture bag and fixing rods. This clamping method requires manual tightening of the bolts, making it inconvenient to operate. Utility Model Content

[0022] Example 1 Reference Figures 1-8 The first embodiment of this application provides a knob-type culture bag fixing device, comprising: The horizontal panel 10 has a positioning groove 11 extending in a first direction; A flip plate 20 is disposed in the slot of the positioning groove 11; The outer wall of the flip plate 20 extending along the first direction can form a limiting space between it and the inner wall of the positioning groove 11 for limiting the end of the culture bag. The flip plate 20 is connected to a rotating component, which drives the flip plate 20 to flip so that the limiting space can be selectively reduced to clamp and limit the end of the culture bag, or the limiting space can be increased to release the clamping and limiting state of the end of the culture bag.

[0023] In this embodiment, two knob-type culture bag fixing devices are typically used together when clamping and fixing the culture bag. The culture bag is rectangular in shape, and the two knob-type culture bag fixing devices clamp and fix one end of the culture bag respectively. During use, the horizontal plate 10 is usually fixed to the wave-type bioreactor by bolt connection or welding. After the horizontal plate 10 is fixedly installed, the positioning grooves 11 of the horizontal plate 10 of the two knob-type culture bag fixing devices face each other. For example, the two knob-type culture bag fixing devices are arranged side by side in the left-right direction. The groove opening of the horizontal plate 10 of the right knob-type culture bag fixing device faces left, and the groove opening of the horizontal plate 10 of the left knob-type culture bag fixing device faces right, thereby achieving clamping and fixing of the left and right ends of the culture bag. Figure 1 and Figure 2 In this diagram, X represents the first direction and Y represents the second direction. Please refer to the space for the limiting hole 41. Figure 3 As shown, in Figure 3 The direction of the vertical plane is the first direction. Limiting spaces can be formed between the upper end of the flip plate 20 and the upper inner wall of the positioning groove 11, and between the lower end of the flip plate 20 and the lower inner wall of the positioning groove 11. This means the end of the culture bag can enter the positioning groove 11 from either the upper or lower limiting space. It should be noted that a positioning rod is usually provided at the end of the culture bag. The positioning rod and the culture bag are integrated, and the end of the culture bag is limited and fixed by limiting and fixing the positioning rod. Figure 3 The diagram shows the state where the limiting space is at its minimum, meaning the distance between the upper and lower ends of the flip plate 20 and the inner wall of the positioning groove 11 is at its minimum. The flip plate 20 is connected to a rotating assembly, which drives the flip plate 20 to rotate counterclockwise, i.e., the upper end of the flip plate 20 moves to the left and the lower end moves to the right. At this time, the limiting space between the upper end of the flip plate 20 and the inner wall of the positioning groove 11 increases, releasing the end of the culture bag from the limiting state. This allows the end of the culture bag to be removed from the limiting space. Alternatively, the end of the culture bag can be placed into the limiting space, and then the rotating assembly drives the flip plate 20 to rotate clockwise, gradually reducing the limiting space between the upper end of the flip plate 20 and the inner wall of the positioning groove 11, thus achieving the clamping and limiting of the end of the culture bag.

[0024] Example 2 As an optional implementation, this embodiment provides a specific structure of a rotating assembly, including: the rotating assembly includes two rotating units located at both ends of the horizontal plate 10 along a first direction, the rotating unit includes a handle 30, the handle 30 is located on the outer side of the horizontal plate 10 along the first direction, the flip plate 20 is connected to a flip shaft 21, the flip shaft 21 passes through the side wall of the positioning groove 11 and is connected to the handle 30.

[0025] Specifically, the rotating assembly includes two rotating units arranged symmetrically. Typically, both units are operated simultaneously, i.e., both handles 30 are driven to move in the same direction simultaneously, thus flipping the flipping plate 20. The flipping plate 20 is positioned within the positioning groove 11, with a portion of the flipping shaft 21 located within the groove 11 and the handles 30 located outside. A portion of the flipping shaft 21 is located outside the groove 11 and connected to the handles 30. The distance between the axis of the flipping shaft 21 and the upper and lower edges of the flipping plate 20 can be equal, meaning the rotation radius of the upper and lower edges of the flipping shaft 21 is the same during flipping. Similarly, the distance can also be unequal, for example, the distance from the upper edge is greater than the distance from the lower edge, so that the rotation radius of the upper edge of the flipping shaft 21 is greater than the rotation radius of the lower edge during flipping. This allows the culture bag to be fixed at the upper or lower edge depending on actual usage requirements, such as the thickness of the culture bag.

[0026] Optionally, the handle 30 extends along a second direction, with the first direction perpendicular to the second direction. The first end of the handle 30 has a fixing hole 31 extending along the first direction. The fixing hole 31 is used to cooperate with the flip shaft 21. The handle 30 and the flip shaft 21 form a limiting structure along the second direction. The second end of the handle 30 is a movable end, which can drive the flip plate 20 to flip around the axis of the flip shaft 21 through the movable end.

[0027] Specifically, such as Figure 2 As shown, the handle 30 extends along a second direction, with the first direction perpendicular to the second direction, so that a circumferential rotational force can be applied to the flip plate 20 through the movable end of the handle 30.

[0028] Optionally, the handle 30 is provided with a locking hole 32 that communicates with the fixing hole 31. The cross-sectional shape of the flip shaft 21 is square. A fixing bolt is detachably provided in the locking hole 32. The fixing bolt is used to abut against the flip shaft 21 to fix the flip shaft 21 in the fixing hole 31.

[0029] Specifically, the cross-sectional area of ​​the fixing hole 31 on the handle 30 is adapted to the cross-sectional shape of the flip shaft 21, which has a square cross-section. When the flip shaft 21 is inserted into the fixing hole 31 on the handle 30, it ensures that the flip shaft 21 and the handle 30 will not slide relative to each other. This allows the handle 30 to transmit the circumferential rotational force to the flip plate 20 via the flip shaft 21. The fixing bolts secure the flip shaft 21, preventing the handle 30 from detaching from it. This also facilitates the disassembly and installation of the flip shaft 21 and the handle 30.

[0030] Example 3 As an optional implementation, this embodiment provides a specific structure of a rotating unit, including: the rotating unit further includes a connecting plate 40, the connecting plate 40 is disposed on the inner walls of both ends of the positioning groove 11 along the first direction, the end of the flip plate 20 is provided with a mounting plate 22, the mounting plate 22 is provided with a ball-head elastic plunger 23, the connecting plate 40 is provided with at least two limiting holes 41 for cooperating with the ball-head elastic plunger 23, and when the flip plate 20 is flipped, the ball-head elastic plunger 23 can form a limiting structure with one of the limiting holes 41.

[0031] Specifically, such as Figures 2-5 As shown, the connecting plate 40 can be fixed to the inner wall of the positioning groove 11 by bolts or welding, and the connecting plate 40 supports the flipping plate 20. Mounting plates 22 are provided at both ends of the flipping plate 20 along the first direction, and the plane of the mounting plates 22 is perpendicular to the plane of the flipping plate 20. Ball-headed elastic plungers 23 are provided on the mounting plates 22. When the flipping plate 20 is flipped, the mounting plates 22 and the ball-headed elastic plungers 23 on the mounting plates 22 can rotate around the axis of the flipping shaft 21 along with the flipping plate 20. Limiting holes 41 are provided on the connecting plate 40. When the flipping plate 20 is flipped to a certain angle, part of the ball-headed elastic plunger 23 on the mounting plate 22 can enter the limiting hole 41, which to a certain extent acts as a limiting structure to maintain the position of the flipping plate 20. When it is necessary to drive the flipping plate 20 to flip, only external force needs to be applied to the handle 30 to overcome the deformation of the ball-headed elastic plunger 23, causing part of the ball-headed elastic plunger 23 to retract from the limiting hole 41.

[0032] Optionally, the connecting plate 40 has a through hole 43, a bushing 50 is provided in the through hole 43, the bushing 50 is sleeved on the flip shaft 21, and the edge of the cross plate 10 is provided with a semi-circular hole 12 for the bushing 50 to pass through.

[0033] Specifically, since the cross-sectional shape of the flip shaft 21 is square, it cannot be rotated solely by itself. A bushing 50 is fitted over the flip shaft 21 so that the flip shaft 21 actually rotates around the axis of the bushing 50 during the flipping process, with the bushing 50 rotating synchronously with the flip shaft 21. A semi-circular hole 12 is provided on the horizontal plate 10 to ensure that the flip plate 20 is positioned at the opening of the positioning groove 11 while also ensuring that the bushing 50 can pass through the side wall of the positioning groove 11. In this embodiment, the horizontal plate 10 supports the connecting plate 40, and the handle 30, bushing 50, flip plate 20, and flip shaft 21 are all supported by the connecting plate 40.

[0034] Optionally, the distance from the axis of all the limiting holes 41 to the axis of the flipping shaft 21 is equal.

[0035] Specifically, since both the flip plate 20 and the mounting plate 22 rotate around the axis of the flip shaft 21, meaning the ball-head elastic plunger 23 moves in an arc along the axis of the flip shaft 21, the distance from the axis of all the limiting holes 41 to the axis of the flip shaft 21 is made equal to ensure that the ball-head elastic plunger 23 can enter any one of the limiting holes 41. In this embodiment, the number of limiting holes 41 is set to two. When the ball-head elastic plunger 23 is aligned with one of the limiting holes 41, it indicates that it is in the open state; when the ball-head elastic plunger 23 is aligned with the other limiting hole 41, it indicates that it is in the closed state.

[0036] Optional, such as Figure 8 As shown, the ball-head elastic plunger 23 includes an abutment post 232, an abutment ball 231, and a return spring 233. The abutment post 232 has a spring groove 234. The abutment ball 231 is located in the spring groove 234. The return spring 233 is located between the abutment ball 231 and the inner wall of the spring groove 234. A portion of the abutment ball 231 protrudes from the spring groove 234 and can form a limiting structure with the limiting hole 41.

[0037] Specifically, the abutment post 232 is mounted on the mounting plate 22, which can be fixed by threaded connection, bonding, or welding. During use, the relative position of the abutment post 232 and the mounting plate 22 will not change. The return spring 233 is in a compressed state, and the return spring 233 applies a pushing force to the abutment ball 231. Even though the abutment ball 231 always tends to move closer to the connecting plate 40, when the abutment ball 231 moves to the position aligned with the limiting hole 41, under the action of the return spring 233, the abutment ball 231 automatically enters the limiting hole 41 to complete the locking. It should be noted that the abutment ball 231 will not completely enter the limiting hole 41, but only partially enters the limiting hole 41. When an external force is applied to the handle 30, the edge of the limiting hole 41 applies a horizontal component force to the abutment ball 231. When the force of the return spring 233 is overcome, the abutment ball 231 can automatically exit from the limiting hole 41, thus achieving automatic unlocking. The unlocking and locking process is convenient and quick.

[0038] Optional, such as Figure 6 As shown, the connecting plate 40 is also provided with a limiting protrusion 42. When the flip plate 20 is flipped, the mounting plate 22 can form a limiting structure with the limiting protrusion 42.

[0039] Specifically, by setting a limiting protrusion 42, the limiting protrusion 42 can limit the mounting plate 22, thereby preventing the flip plate 20 from continuing to flip, thus limiting the maximum angle of the flip plate 20 flipping.

[0040] Optionally, the sidewall of the flip plate 20 is provided with reinforcing ribs 24 extending in the first direction.

[0041] Specifically, by setting reinforcing ribs 24, the structural strength of the flip plate 20 can be enhanced. The cross-sectional shape of the reinforcing ribs 24 is V-shaped.

[0042] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
