Description

Technical Field

[0001] This application relates to the field of cell fluid bag suspension technology, and more particularly to a filter fixing hook structure. Background Technology

[0002] Hooks are components used to suspend cell culture bags. Existing cell culture bag suspension solutions typically involve installing a weighing sensor and a crossbeam support above the equipment. The crossbeam support is used to install the required cell culture bag hooks, and the hooks are fixed to the crossbeam support with screws. While this solution meets the basic requirements for suspending cell culture bags, if the pipeline connecting the cell culture bag to the filter is too long, the filter cannot be placed vertically. In fact, the filter may even come into contact with the equipment platform below, causing the filter to tilt severely. Consequently, the cell culture inside the filter may not be able to flow out completely, resulting in cell culture residue in the filter. This leads to the incomplete utilization and waste of cell culture. Utility Model Content

[0003] The main objective of this application is to provide a filter fixing hook structure, which aims to solve the technical problem in the prior art where cell fluid bags are usually connected to filters, and the cell fluid bags and filters are connected by pipes. The filters lack a fixing structure and are prone to tilting, which leads to the incomplete discharge of cell fluid inside the filter and waste of cell fluid.

[0004] To achieve the above objectives, this application provides a filter fixing hook structure, comprising: Load-bearing components; A hook, which is connected to the carrier, is used to suspend the cell fluid bag; The bracket is connected to the load-bearing member; A fastener is connected to the bracket, the fastener having a mounting groove for mounting a filter, and the cell fluid bag and the filter are connected to each other via a connecting tube; The bracket extends along a first direction and has at least two positioning holes. All the positioning holes are arranged along the first direction. The bracket has a connecting groove corresponding to the positioning hole. The connecting groove extends along a second direction. One end of the connecting groove communicates with the positioning hole and the other end penetrates the outer wall of the bracket. The connecting pipe can pass through the positioning hole via the connecting groove.

[0005] Optionally, the width of the connection between the connecting groove and the positioning hole along the first direction is smaller than the inner diameter of the positioning hole.

[0006] Optionally, the width of the connecting groove gradually increases in the direction away from the positioning hole.

[0007] Optionally, the first direction and the second direction are perpendicular to each other.

[0008] Optionally, the opening directions of the connecting slots corresponding to adjacent positioning holes are opposite, so that when the connecting tube is spirally wound around the bracket in the circumferential direction, the connecting tube can sequentially pass through the positioning holes.

[0009] Optionally, the fastener has two mounting slots arranged side by side along the second direction, the two mounting slots having opening structures facing away from each other, and the opening structures of the mounting slots being deformable so that the mounting slots can clamp the filter.

[0010] Optionally, the fastener has a limiting groove extending along a first direction, the limiting groove being adapted to fit the bracket so that the bracket can pass through the limiting groove, the fastener having a locking hole communicating with the limiting groove, the locking hole being coaxial with any of the positioning holes, and being able to be fixed by a screw when the locking hole is aligned with one of the positioning holes.

[0011] Optionally, the limiting groove is connected to the mounting groove in the second direction, so that the bracket can enter the limiting groove in the second direction.

[0012] Optionally, it also includes a connecting block, the hook being hinged to the connecting block, the connecting block having a first through hole, the bearing having a second through hole, and the bracket having a third through hole, the first through hole, the second through hole and the third through hole being coaxially arranged, and the connecting block, the bearing and the bracket being fixed by a bolt assembly.

[0013] Optionally, it also includes a positioning post extending along a first direction, with a positioning box at the end of the positioning post, a weighing sensor inside the positioning box, and the carrier being configured to be interconnected with the weighing sensor.

[0014] The beneficial effects that this application can achieve are: This application proposes a filter fixing hook structure. By adding a bracket to the outside of the hook and setting a fixing component on the bracket, the fixing component supports and fixes the filter, ensuring that the filter will not tilt after installation and that the filter will always be in a vertical position. The filter and the cell fluid bag are interconnected by a connecting tube. The connecting tube can be fixed by a connecting groove and a positioning hole set on the bracket. Even when the connecting tube is long, the positioning hole can still provide auxiliary fixation for the connecting tube. The connecting groove runs through the side wall, allowing any part of the middle of the connecting tube to enter the positioning hole through the connecting groove, without the need for the end of the connecting tube to pass through multiple connecting holes sequentially. This makes it more convenient and flexible to install the connecting tube into or remove it from the positioning hole. Attached Figure Description

[0022] Example 1 Reference Figures 1-6 The first embodiment of this application provides a filter 30 fixing hook 50 structure, including: 40 bearing components; Hook 50, which is connected to the carrier 40, is used to suspend the cell fluid bag; The bracket 10 is connected to the bearing member 40; The fastener 20 is connected to the bracket 10 and has a mounting groove 21 for mounting the filter 30. The cell fluid bag and the filter 30 are connected to each other by a connecting tube. The bracket 10 extends along a first direction and has at least two positioning holes 11. All the positioning holes 11 are arranged and distributed along the first direction. The bracket 10 has a connecting groove 12 corresponding to the positioning hole 11. The connecting groove 12 extends along a second direction. One end of the connecting groove 12 is connected to the positioning hole 11 and the other end penetrates the outer wall of the bracket 10. The connecting pipe can pass through the positioning hole 11 through the connecting groove 12.

[0023] In this embodiment, the support member 40 is a cylindrical structure, positioned above the workbench surface. During use, the support member 40 provides load-bearing capacity for the hook 50, support 10, and fixing member 20. The hook 50 is connected to the support member 40 and is used to suspend the cell fluid bag. The support 10 is a cuboid plate structure, with its upper end connected to the support member 40. The support 10 and the support member 40 can be connected by welding or bolts. Figure 1 As shown, X represents the first direction, and Y represents the second direction. The first direction is vertical, and the second direction is horizontal. Multiple positioning holes 11 are provided on the support 10. The axes of all positioning holes 11 are parallel to each other, and all positioning holes 11 are arranged vertically. At least two positioning holes 11 are provided; both holes 11 can be used to fix the connecting tube, or one hole can be used to fix the fixing component 20, and the other hole can be used to fix the connecting tube. During use, the hook 50 is located above the filter 30, and the cell fluid bag is suspended on the hook 50. The cell fluid bag and the filter 30 are connected by a connecting tube. It should be noted that the structure of the cell fluid bag and the connecting tube is not shown in the attached diagram. The middle part of the connecting tube can enter the positioning hole 11 through the connecting groove 12. When the connecting tube enters the positioning hole 11, it can play a role in fixing the connecting tube and fixing it to the bracket 10. This allows the middle part of the connecting tube to be fixed by the bracket 10 when the length of the connecting tube is too long, preventing the connecting tube from shaking randomly. It also prevents the lowest point of the downward bend of the middle part of the connecting tube from being lower than the lower end of the connecting tube due to the excessive length of the connecting tube. This avoids residual cell fluid in the lower part of the connecting tube, ensuring that the cell fluid in the connecting tube can smoothly enter the filter 30.

[0024] Example 2 As an optional implementation, this embodiment provides a specific structure of the bracket 10, including: the width of the connection between the connecting groove 12 and the positioning hole 11 along the first direction is smaller than the inner diameter of the positioning hole 11.

[0025] Specifically, such as Figure 2 As shown in the figure, M represents the width of the connection between the connecting groove 12 and the positioning hole 11 along the first direction, and N represents the inner diameter of the positioning hole 11. By making the width of the connection between the connecting groove 12 and the positioning hole 11 along the first direction smaller than the inner diameter of the positioning hole 11, the connecting groove 12 first deforms the connecting pipe as it enters the positioning hole 11 from the connecting groove 12. Once the connecting pipe enters the positioning hole 11, it can recover its deformation. This ensures that the connecting pipe can enter the positioning hole 11 from the connecting groove 12, and the positioning hole 11 can limit the connection pipe, preventing it from easily exiting the positioning hole 11.

[0026] Optionally, the width of the connecting groove 12 gradually increases in the direction away from the positioning hole 11.

[0027] Specifically, the inner wall of the connecting groove 12 can be curved or flat. In this embodiment, the inner wall of the connecting groove 12 is curved. The inner wall of the connecting groove 12 can guide the connecting pipe, so that when the connecting pipe moves in the direction close to the positioning hole 11 within the connecting groove 12, the connecting pipe can deform and enter the positioning hole 11. After the connecting pipe enters the positioning hole 11, the connecting pipe returns to its original shape. The transition between the connecting groove 12 and the positioning hole 11 can limit the connecting pipe, ensuring that the connecting pipe will not arbitrarily exit from the positioning hole 11 into the connecting groove 12.

[0028] Optionally, the first direction and the second direction are perpendicular to each other.

[0029] Optionally, the opening directions of the connecting grooves 12 corresponding to adjacent positioning holes 11 are opposite, so that when the connecting tube is spirally wound around the bracket 10 in the circumferential direction, the connecting tube can pass through the positioning holes 11 in sequence.

[0030] Specifically, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, there are seven positioning holes 11. It should be noted that the number of positioning holes 11 can also be five, three, etc. The orientation of the connecting groove 12 alternates between left and right from top to bottom, allowing the connecting tube to spirally extend circumferentially around the outer periphery of the bracket 10. By alternating the orientation of the connecting groove 12, the two sides of the spirally extending connecting tube can be engaged, improving the stability of fixing the connecting tube to the bracket 10 and preventing the connecting tube from shaking. The middle part of the connecting tube can enter the positioning hole 11 through the connecting groove 12, allowing the connecting tube to be fixed in any positioning hole 11 on the bracket 10, or removed from any positioning hole 11, without needing to sequentially remove the connecting tube from the positioning holes 11 from top to bottom or bottom to top. This increases the flexibility of adjusting the position of the connecting tube fixed to the bracket 10, making it easier for the user.

[0031] Example 3 As an optional implementation, this embodiment provides a specific structure of the fastener 20, including: the fastener 20 has two mounting grooves 21 arranged side by side along a second direction, the two mounting grooves 21 have opening structures 22 arranged in opposite directions, and the opening structures 22 of the mounting grooves 21 can deform so that the mounting grooves 21 can clamp the filter 30.

[0032] Specifically, by providing two mounting slots 21 on the fixing member 20, each mounting slot 21 can clamp and fix one filter 30, increasing the number of filters 30 that can be installed. Furthermore, the two mounting slots 21 have opening structures 22 facing away from each other. By providing the opening structures 22, deformation can occur at the mounting slots 21, meaning the shape of the filter 30 typically matches the inner wall of the mounting slot 21. For example, if the filter 30 is cylindrical, the inner wall of the mounting slot 21 will also be arc-shaped. When the filter 30 is installed in the mounting slot, the filter 30 compresses the opening structure 22 of the mounting slot 21, increasing its size, thereby allowing the mounting slot 21 to tightly hold the filter 30, thus quickly clamping and fixing the filter 30 within the mounting slot 21. Furthermore, a guide groove extending along the first direction can be provided on the inner wall of the mounting groove 21, and a guide protrusion adapted to the guide groove can be provided on the outer wall of the filter 30. The guide protrusion and the guide groove cooperate to position the filter 30 in the mounting groove 21, and at the same time ensure that the filter 30 will not move circumferentially after being installed in the mounting groove 21.

[0033] Optional, such as Figure 6 As shown, the fastener 20 has a limiting groove 23 extending along a first direction. The limiting groove 23 is adapted to fit the bracket 10 so that the bracket 10 can pass through the limiting groove 23. The fastener 20 has a locking hole 24 communicating with the limiting groove 23. The locking hole 24 can be coaxial with any positioning hole 11. When the locking hole 24 is aligned with one of the positioning holes 11, it can be fixed by a screw 25.

[0034] Specifically, by providing a limiting groove 23 extending along the first direction on the fixing member 20, the fixing member 20 can be fitted onto the bracket 10 from the lower end of the bracket 10 and can move along the extension direction of the bracket 10. This allows the relative position of the fixing member 20 on the bracket 10 to be adjusted according to actual usage needs, thereby adjusting the distance between the fixing member 20 and the hook 50. This allows the position of the fixing member 20 on the bracket 10 to be adjusted according to the length of the connecting pipe or the relative height of the worktable. When the locking hole 24 on the fixing member 20 is aligned with one of the positioning holes 11, the fixing member 20 can be fixed to the bracket 10 using screws 25. In this embodiment, the positioning hole 11 can be used to fix the connecting pipe, and it can also be used to fix the fixing member 20.

[0035] Optionally, the limiting groove 23 is connected to the mounting groove 21 in the second direction so that the bracket 10 can enter the limiting groove 23 in the second direction.

[0036] Specifically, one end of the limiting groove 23 is connected to one of the mounting grooves 21, and the other end of the limiting groove 23 is the busy end. This ensures that when the fastener 20 is installed onto the bracket 10, the fastener 20 can move along the second direction, first entering the mounting groove 21 through the opening structure 22 on the mounting groove 21, and then entering the limiting groove 23. That is, the fastener 20 can be installed onto the bracket 10 from any height, instead of only being able to be installed from bottom to top, thus improving the ease of installation of the fastener 20.

[0037] Optionally, it also includes a connecting block 51, with a hook 50 hinged to the connecting block 51. The connecting block 51 has a first through hole, the bearing member 40 has a second through hole, and the bracket 10 has a third through hole. The first through hole, the second through hole, and the third through hole are coaxially arranged and fixed by bolt assembly.

[0038] Specifically, by installing the connecting block 51, the bearing 40, and the bracket 10 using the same bolt assembly, it is convenient to install and disassemble the bracket 10 and the hook 50 as a whole during the installation and disassembly process, thereby improving the efficiency of disassembly and installation.

[0039] Optionally, it also includes a positioning post 41 extending along the first direction, with a positioning box 42 provided at the end of the positioning post 41, a weighing sensor 43 provided inside the positioning box 42, and the carrier 40 configured to be interconnected with the weighing sensor 43.

[0040] Specifically, the positioning column 41 can be installed at the target position by bolts or welding. A positioning box 42 is provided at the upper end of the positioning column 41, and a weighing sensor 43 is installed inside the positioning box 42. A clearance hole is provided through the positioning box 42 for the carrier 40 to pass through. The upper end of the carrier 40 is connected to the weighing sensor 43, and the lower end of the carrier 40 is connected to the hook 50, the bracket 10, and other structures. The weighing sensor 43 can weigh the entire assembly formed by the hook 50, the connector, the bracket 10, the fixing member 20, the connecting pipe, and the filter 30. During the process of cell fluid being discharged after filtration by the filter 30, the change in the reading of the weighing sensor 43 allows for real-time monitoring of the weight of the discharged cell fluid.

[0041] 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.
