[0001] This utility model relates to the field of multi-purpose cell culture container clamps, specifically a multi-purpose cell culture container fixing clamp. Background Technology

[0002] Multipurpose cell culture containers are containers that can adapt to various uses and experimental conditions during cell culture. In order to maintain the stable position of the cell culture container and prevent it from moving or tilting during the culture process, it is necessary to use fixing clamps to hold and fix the cell culture container.

[0003] A Chinese patent with authorization announcement number CN 210560487 U discloses a novel fixing clamp for cell culture containers, including a box body, a door panel, a battery, an observation window, a handle, a sterilization lamp switch, a sterilization lamp, a shaft bracket, casters, brake pads, an adjustable culture flask fixing frame structure, an adjustable culture bag hanging frame structure, and an adjustable mounting base structure. The door panel is shafted to the left side of the box body; the battery is embedded in the left front of the door panel; the observation window is embedded in the middle of the front of the door panel; and the handle is screwed to the left rear of the door panel. The fixing rod, connecting sleeve, tightening bolt, placement plate, insertion tube, and fixing ring of this invention allow for the secure fixing of culture flasks, making it easier for users to fix the culture flasks.

[0004] Existing clamping fixtures are difficult to control in terms of clamping force when holding multi-purpose cell culture containers, and are prone to excessive clamping force that can damage the container, resulting in poor protection of the device; therefore, a multi-purpose cell culture container clamping fixture is proposed to address the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes a multi-purpose cell culture container fixing clamp.

[0006] The technical solution adopted by this utility model to solve its technical problem is a multi-purpose cell culture container fixing clamp, including a base, a groove on the base, a rotating block placed in the groove, a placement platform mounted on the rotating block, a cell culture flask placed on the placement platform, a rotating shaft passing through the placement platform, connecting blocks symmetrically mounted on the base, the connecting blocks sleeved around the rotating shaft and rotatably connected to the rotating shaft, a sliding groove on the placement platform, two sets of sliders symmetrically assembled in the sliding groove, a clamping plate mounted on the slider, an assembly groove inside the clamping plate, multiple sets of plate grooves on the inner wall of the assembly groove, pressure plates assembled in the plate grooves, multiple sets of rod holes on the side wall of the clamping plate, limit rods assembled in the rod holes, an anti-slip rubber pad installed at one end of the limit rod, a limit block installed at the other end of the limit rod, and a spring installed between the limit block and the inner wall of the assembly groove. A first lead screw is rotatably mounted on the inner wall of the slide groove. The threads on the first lead screw are symmetrical and opposite in direction. A first damping wheel is fixedly mounted on one end of the first lead screw. The first damping wheel is in contact with the side wall of the placement platform. A lifting groove is opened on the inner wall of the assembly groove. A lifting rod is slidably mounted in the lifting groove.

A screw rod passes through the threaded hole and is rotatably connected to the lifting rod. A knob is installed on the top side of the screw rod. The limiting rod on the clamping plate first contacts the side wall of the cell culture bottle to limit the cell culture bottle. Then all the pressure plates press and fix all the limiting rods. At this time, the cell culture bottle is clamped and fixed by the limiting rod. This structure clamps and fixes the cell culture bottle by the limiting rod, which will not cause damage to the container due to excessive clamping force and is beneficial to improving the protection of the device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4As shown, a multi-purpose cell culture container fixing clamp includes a base 1 with a groove on the base 1. A rotating block 2 is placed in the groove, and a placement platform 3 is mounted on the rotating block 2. A cell culture flask 28 is placed on the placement platform 3, and a rotating shaft 4 passes through the placement platform 3. Connecting blocks 5 are symmetrically mounted on the base 1, and the connecting blocks 5 are sleeved around the rotating shaft 4 and rotatably connected to the rotating shaft 4. A sliding groove 6 is provided on the placement platform 3, and two sets of sliding blocks 9 are symmetrically assembled in the sliding groove 6. A clamping plate 10 is mounted on the sliding block 9. An assembly groove 11 is provided inside the clamping plate 10. Multiple sets of plate grooves 12 are provided on the inner wall of the assembly groove 11, and pressure plates 13 are assembled in the plate grooves 12. Multiple sets of rod holes 14 are provided on the side wall of the clamping plate 10, and rod holes 14 are assembled in the rod holes 14. A limiting rod 15 is provided, with an anti-slip rubber pad 16 installed at one end and a limiting block 17 installed at the other end. A spring 18 is installed between the limiting block 17 and the inner wall of the assembly groove 11. A first lead screw 7 is rotatably installed on the inner wall of the slide groove 6. The threads on the first lead screw 7 are symmetrically opposite. A first damping wheel 8 is fixedly installed at one end of the first lead screw 7. The first damping wheel 8 is in contact with the side wall of the placement platform 3. A lifting groove 19 is provided on the inner wall of the assembly groove 11. A lifting rod 20 is slidably assembled in the lifting groove 19. The lifting rod 20 is fixedly connected to the side wall of multiple sets of pressure plates 13. A rod seat 21 is installed on the clamping plate 10. A threaded hole is provided in the rod seat 21. A screw 22 passes through the threaded hole and is rotatably connected to the lifting rod 20. A knob 23 is installed on the top side of the screw 22. During operation, existing clamping devices struggle to control the clamping force when holding multi-purpose cell culture containers, easily leading to excessive clamping force and damage to the container, resulting in poor device protection. By placing the cell culture flask 28 on the placement platform 3, rotating the first damping wheel 8 drives the first lead screw 7 to rotate. The first lead screw 7 drives two sets of sliders 9 to move synchronously relative to each other. The two sets of sliders 9 drive two sets of clamping plates 10 to move synchronously relative to each other. The two sets of clamping plates 10 move towards the cell culture flask 28. The limiting rod 15 on the clamping plate 10 first contacts the side wall of the cell culture flask 28, and is then pushed back by the cell culture flask 28. Inside the assembly slot 11, the limiting rod 15 presses down on the spring 18. The remaining limiting rods 15 surround the cell culture flask 28, limiting its position. Then, by rotating the two sets of knobs 23, the knobs 23 drive the screw 22 to rotate on the rod seat 21. At the same time, the screw 22 pushes the lifting rod 20 to move vertically downward. The lifting rod 20 drives all the pressure plates 13 to move vertically downward, and all the pressure plates 13 press and fix all the limiting rods 15. At this time, the cell culture flask 28 is clamped and fixed by the limiting rods 15. This structure clamps and fixes the cell culture flask 28 by the limiting rods 15, preventing excessive clamping force from damaging the container and improving the protection of the device.

[0020] Please see Figure 5As shown, two sets of fixing blocks are symmetrically installed on the base 1. A second lead screw 24 is rotatably installed on the two sets of fixing blocks. A second damping wheel 29 is installed at one end of the second lead screw 24. The second damping wheel 29 is in contact with the side wall of the fixing block. A moving block 25 is sleeved on the second lead screw 24. A rack 26 is installed on the moving block 25. A gear 27 is fixedly sleeved on the rotating shaft 4. The gear 27 and the rack 26 mesh with each other. During operation, the existing fixing clamp cannot adjust the angle of the container as needed when clamping the multi-purpose cell culture container, resulting in poor adjustability of the device. By rotating the second damping wheel 29, the second lead screw 24 is rotated. The second lead screw 24 drives the rack 26 on it to move horizontally. The rack 26 pushes the gear 27 to rotate. The gear 27 drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the placement platform 3 to rotate. The placement platform 3 drives the cell culture flask 28 clamped on it to rotate, realizing the angle adjustment of the cell culture flask 28, which is beneficial to improving the adjustability of the device.

[0021] Working principle: Existing clamping fixtures have difficulty controlling the clamping force when holding multi-purpose cell culture containers, easily causing damage due to excessive clamping force, resulting in poor device protection. By placing the cell culture flask 28 on the placement platform 3, rotating the first damping wheel 8 drives the first lead screw 7 to rotate. The first lead screw 7 drives the two sets of sliders 9 on it to move synchronously relative to each other. The two sets of sliders 9 drive the two sets of clamping plates 10 to move synchronously relative to each other. The two sets of clamping plates 10 move towards the cell culture flask 28. The limiting rods 15 on the clamping plates 10 first contact the side wall of the cell culture flask 28. The limiting rods 15 in contact with the side wall of the cell culture flask 28 are pushed back into the assembly slot 11 by the cell culture flask 28. The limiting rods 15 press the springs 18 on them. The remaining limiting rods 15 surround the cell culture flask 28, limiting its position. Then, by rotating the two sets of knobs 23, the knobs 23 drive the screw 22 to rotate on the rod seat 21. At the same time, the screw 22 pushes... The lifting rod 20 moves vertically downwards, causing all the pressure plates 13 to move vertically downwards as well. All the pressure plates 13 press and fix all the limiting rods 15. At this time, the cell culture flask 28 is clamped and fixed by the limiting rods 15. This structure clamps and fixes the cell culture flask 28 by the limiting rods 15, preventing damage to the container due to excessive clamping force, thus improving the device's protective properties. Existing fixing clamps cannot adjust the angle of the container as needed during the clamping of multi-purpose cell culture containers, resulting in poor adjustability of the device. By rotating the second damping wheel 29, the second damping wheel 29 drives the second lead screw 24 to rotate. The second lead screw 24 drives the rack 26 on it to move horizontally. The rack 26 pushes the gear 27 to rotate. The gear 27 drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the placement stage 3 to rotate. The placement stage 3 drives the cell culture flask 28 clamped on it to rotate, thus realizing the angle adjustment of the cell culture flask 28 and improving the device's adjustability.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
