Description

Technical Field

[0001] This utility model relates to the field of biological laboratory equipment technology, specifically a multifunctional support for a suspended cell culture plate. Background Technology

[0002] Cell culture plates are essential basic vessels in biological, medical, and chemical laboratories. They are mainly divided into ordinary plates for adherent cell growth and special culture plates for suspension cell culture. In order to ensure that cells can be effectively suspended and aggregated during shaking culture, the bottom of the suspension cell culture plate is usually designed as a "U" shape or a circular bottom. This structure results in a relatively high overall height and a small bottom area in contact with the table surface, thus making the center of gravity unstable and the inherent stability poor.

[0003] When performing cell inoculation, medium replacement, reagent addition, or sampling in a sterile operating table (clean bench), the culture plate needs to be temporarily and statically placed on the table. Because the culture plate is lightweight and has little friction with the table surface, it is very easy for it to slip or tip over due to the operator's sleeve hooking, tubing pulling, or accidental collision. Once this happens, it will not only cause damage to the expensive culture plate and loss of precious samples, but may also cause biosafety contamination or chemical leakage risks, with serious consequences.

[0004] Currently, laboratories generally lack dedicated anti-tipping devices for these types of culture plates. Operators sometimes use simple stands of fixed height or arbitrarily block the tipping with other objects, but these methods have obvious drawbacks: First, they cannot be adapted to different sizes (such as 6-well, 12-well, and 96-well) of suspension culture plates, resulting in poor versatility; second, the existing stands are of fixed height, which cannot accommodate the operating habits of experimenters of different heights. Taller individuals need to bend over for extended periods, which can easily lead to muscle fatigue and increase operational errors, while shorter individuals may experience reduced operational accuracy due to poor viewing angles, indicating insufficient consideration of ergonomics.

[0005] Therefore, there is an urgent need in this field for a dedicated support that can balance stability and anti-tipping, multi-size compatibility, height adjustment, and integrated auxiliary functions, in order to create a safe, efficient, and ergonomic experimental operating environment. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a multifunctional support for suspended cell culture plates, which has the advantages of effectively fixing culture plates of different sizes and preventing them from tipping over, thus solving the problems mentioned in the background art.

[0007] This utility model provides the following technical solution: a multifunctional support for a suspended cell culture plate, including a base, a test tube rack fixedly provided on one side of the base for placing experimental test tubes, centrifuge tubes and other glassware for easy access, a counterweight fixedly provided at the bottom end of the base to lower the overall center of gravity and enhance the stability of the support, a base plate fixedly provided at the bottom end of the counterweight, and an anti-slip pad fixedly provided at the bottom end of the base plate to increase the friction with the operating table surface and further prevent the support from sliding.

[0008] The top of the base is slidably provided with a column, which can slide vertically on the base to adjust the height of the support body. A limiting component is provided on the top of one side of the base to limit the column. When the column is adjusted to a suitable height, it is fixed by the limiting component to prevent it from sliding on its own. A support plate is fixed on the top of the column to support the suspended cell culture plate.

[0009] The top of the tray is slidably equipped with a pressure plate, which can slide up and down relative to the tray. Both the bottom of the pressure plate and the top of the tray are engaged with silicone pads. The opposing silicone pads can flexibly clamp and fix the suspended cell culture plate placed on the tray when the pressure plate is pressed down, avoiding scratching the culture plate. A counterweight is fixed in the middle of the top of the pressure plate. The weight of the counterweight assists the pressure plate to press down automatically, achieving stable clamping of the culture plate. The top of the pressure plate is equipped with a lifting component for convenient lifting of the pressure plate when placing or removing the culture plate.

[0010] As a preferred embodiment of this utility model, the limiting component includes a rod, a spring sleeved on the surface of the rod, a baffle plate on one side of the spring, the baffle plate being fixedly connected to the rod, and a plurality of rod slots corresponding to the rod being opened on one side of the column. Under the action of the spring, the rod tends to insert into the rod slot. When the height needs to be adjusted, the rod is pulled outward to disengage it from the current rod slot, and then the column is slid to the desired height. The rod is then released, and under the action of the spring, the rod is inserted into the rod slot of the corresponding height, thus achieving limiting and fixing.

[0011] As a preferred technical solution of this utility model, a slide rail is provided in the middle of the top of the base, the column is slidably connected to the slide rail, the slide rail provides guidance for the sliding of the column, a telescopic opening is provided on one side of the slide rail, the baffle is slidably connected to the inside of the telescopic opening, a concentric hole communicating with the telescopic opening is provided on the top of one side of the base, the insertion rod is slidably connected to the concentric hole, and the concentric hole provides a channel and guidance for the movement of the insertion rod.

[0012] As a preferred embodiment of this utility model, the lifting assembly includes a top plate with a through hole in the middle. A lifting rod is slidably connected to the through hole. The bottom end of the lifting rod is rotatably connected to the middle of the top of the second counterweight via a bearing. A bent rod is fixedly provided at the bottom of the lifting rod to limit its movement. By pulling the lifting rod upward, the pressure plate can be raised, thereby facilitating the placement and removal of the culture plate. The bearing connection allows relative rotation between the lifting rod and the second counterweight.

[0013] As a preferred technical solution of this utility model, one side of the through hole is provided with a channel that can ensure the lifting rod can be raised and lowered. This channel allows the lifting rod to move freely in the vertical direction. The top of the top plate is provided with a socket for limiting the bending rod. When the pressure plate does not need to be lifted, the bending rod can be rotated and inserted into the socket, thereby locking the lifting rod and the pressure plate in the lifting position, which is convenient for operation by both hands.

[0014] As a preferred embodiment of this utility model, guide posts are fixedly provided at the four corners of the top of the pallet, the bottom of the top plate is fixedly connected to the top of the guide posts, and guide sleeves are fixedly provided at the four corners of the pressure plate and slidably connected to the guide posts. The cooperation between the guide posts and the guide sleeves ensures that the pressure plate remains stable during the lifting and lowering process and does not tilt.

[0015] As a preferred technical solution of this utility model, recesses are provided on both sides of the top of the tray and both sides of the bottom of the pressure plate, and protrusions are fixed on both sides of the silicone pad. The protrusions are engaged with the interior of the recesses. This engaging connection method makes the installation and replacement of the silicone pad very convenient, and facilitates cleaning or the use of pads of different materials as needed.

[0016] As a preferred technical solution of this utility model, the bottom end of the counterweight is fixedly connected to one side of the top of the base, and the bottom end of the test tube rack is fixedly connected to the other side of the top of the base. This layout makes the overall weight distribution of the support reasonable and the structure compact.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The multifunctional support of this suspended cell culture plate, through the design of the first counterweight and anti-slip pad at the bottom, greatly reduces the overall center of gravity and increases the friction with the table surface, fundamentally preventing the support from sliding and tipping. Through the sliding cooperation between the column and the slide and the insertion and removal positioning of the limiting component, the height of the tray can be quickly and infinitely adjusted to meet the operating needs of experimental personnel of different heights, which is in line with ergonomics. Utilizing the self-weight of the second counterweight, the culture plate placed on the tray is subjected to uniform vertical pressure through the pressure plate and silicone pad, which can stably fix culture plates of different specifications. It is highly versatile and easy to pick up and put down.

[0018] 2. The multifunctional support of this suspension cell culture plate can easily lift the heavy pressure plate through the lifting component and lock it in the lifted position after rotation, which greatly facilitates the operation of picking up and putting down the culture plate. The integrated test tube rack makes it convenient to centrally place experimental supplies. The silicone pad adopts a snap-fit ​​connection, which is easy to disassemble for thorough cleaning and disinfection, effectively preventing cross-contamination. Attached Figure Description

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6A multifunctional support for a suspension cell culture plate includes a base 1, a test tube rack 3 fixed on one side of the base 1 for storing test tubes, centrifuge tubes, etc., for experiments, a counterweight 2 fixed at the bottom of the base 1, a base plate 4 fixed at the bottom of the counterweight 2, and an anti-slip pad 5 fixed at the bottom of the base plate 4. The anti-slip pad 5 can be made of rubber or silicone. A column 6 is slidably mounted on the top of the base 1. A limiting component 8 is provided on the top of one side of the base 1 to limit the column 6. After sliding and adjusting the column 6, the column 6 can be quickly limited by the limiting component 8. A support plate 9 is fixedly mounted on the top of the column 6. A pressure plate 10 is slidably mounted on the top of the support plate 9. A silicone pad 11 is engaged with the bottom of the pressure plate 10 and the top of the support plate 9. A counterweight 12 is fixedly mounted in the middle of the top of the pressure plate 10. A lifting component 13 is provided on the top of the pressure plate 10. The support plate 9 and the pressure plate 10 can limit the suspension cell culture plate by the silicone pad 11. In this embodiment, preferably, the limiting component 8 includes a rod 801, a spring 802 sleeved on the surface of the rod 801, a baffle 803 on one side of the spring 802, the baffle 803 being fixedly connected to the rod 801, a plurality of rod grooves 7 corresponding to the rod 801 being opened on one side of the column 6, a slide rail 14 being opened in the middle of the top of the base 1, the column 6 being slidably connected to the slide rail 14, a telescopic opening 15 being provided on one side of the slide rail 14, the baffle 803 being slidably connected to the inside of the telescopic opening 15, and the base 1 being... The top of the side has a concentric hole 16 that communicates with the telescopic port 15. The insertion rod 801 is slidably connected to the concentric hole 16. Under the action of the spring 802, the front end of the insertion rod 801 is normally inserted into a certain rod groove 7 to lock the height of the column 6. When adjustment is needed, the insertion rod 801 is pulled outward to compress the spring 802, so that the insertion rod 801 is removed from the rod groove 7. The column 6 can then be slid up and down to the required height. After aligning the rod groove 7, the insertion rod 801 is released, and the spring 802 pushes the insertion rod 801 to insert into the new rod groove 7 to complete the fixation. In this embodiment, preferably, the lifting assembly 13 includes a top plate 1301, with a through hole 1302 in the middle of the top plate 1301. A lifting rod 1305 is slidably connected to the through hole 1302. The bottom end of the lifting rod 1305 is rotatably connected to the middle of the top of the counterweight 12 via a bearing. A bent rod 1306 is fixedly provided at the bottom of the lifting rod 1305 to limit its movement. A channel 1303 is provided on one side of the through hole 1302 to ensure the lifting rod 1305 can rise and fall. A bent rod 1306 is provided at the top of the top plate 1301. 06 The limiting insertion port 1304 is used to lift the lifting rod 1305 upward, which can drive the pressure plate 10 to rise and compress the space above the counterweight 12, making it easier to sterilize by cleaning and wiping the silicone pad 11. At this time, the bent rod 1306 can be rotated and inserted into the insertion port 1304 to lock the pressure plate 10 in the lifted position, making it easy to pick up and put down the culture plate. The four corners of the top of the tray 9 are all fixedly provided with guide posts 17. The bottom end of the top plate 1301 is fixedly connected to the top end of the guide post 17. The four corners of the pressure plate 10 are all fixedly provided with guide sleeves 18 that are slidably connected to the guide post 17. In this embodiment, preferably, recesses 20 are provided on both sides of the top of the tray 9 and both sides of the bottom of the pressure plate 10, and protrusions 19 are fixed on both sides of the silicone pad 11. The protrusions 19 are engaged with the interior of the recesses 20, which enables the silicone pad 11 to be quickly installed and removed. In this embodiment, preferably, the bottom end of the counterweight 2 is fixedly connected to one side of the top of the base 1, and the bottom end of the test tube rack 3 is fixedly connected to the other side of the top of the base 1, so as to maintain the stability between the counterweight 2, the test tube rack 3 and the base 1.

[0023] When in use, place the stand on a stable and clean experimental surface. Thanks to the counterweight 2 and anti-slip pad 5 at the bottom, the stand can naturally maintain stability and is not easy to slide. The height of the support plate 9 of this stand can be adjusted according to the operator's height or experimental needs. Gently pull the insertion rod 801 of the limiting component 8 outward (away from the column 6). At this time, the insertion rod 801 will compress the spring 802 and exit from the current rod groove 7 on the side of the column 6. Keep the insertion rod 801 in the pulled-out state and slide the column 6 up and down. The column 6 will move smoothly in the slide 14 of the base 1 until the support plate 9 reaches the desired height. Observe the column 6 and align the insertion rod 801 with the rod groove 7 at the target height. Then release the insertion rod 801. Under the elastic force of the spring 802, the insertion rod 801 will automatically spring into the new rod groove 7 and lock the column 6 firmly. Before placing or removing the culture plate, the pressure plate 10 needs to be lifted and locked. Hold the lifting rod 1305 of the lifting assembly 13 and lift it vertically upward. The lifting rod 1305 drives the counterweight 12 and the entire pressure plate 10 to rise together through the bearing. The pressure plate 10 moves smoothly upward along the guide post 17 through the guide sleeves 18 at the four corners without tilting. When the pressure plate 10 is lifted to a sufficient height, rotate the bent rod 1306 horizontally so that it is aligned with the insertion port 1304 on the top plate 1301. Insert the bent rod 1306 downward into the insertion port 1304. At this time, the pressure plate 10 is fixed in the lifting position, which is convenient for operation with both hands. Place the suspension cell culture plate stably on the silicone pad 11 of the tray 9. After placement, unscrew the bent rod 1306 from the socket 1304 and gently lift it upwards. Then slowly lower the lifting rod 1305. Under the weight of the counterweight 12, the pressure plate 10 will naturally descend, and the silicone pad 11 at its bottom will contact the top of the culture plate, thus flexibly and steadily clamping the culture plate between the tray 9 and the pressure plate 10. The test tube rack 3 on the side of the support can be used to store test tubes, centrifuge tubes and other glassware needed during the experiment, making the experimental supplies centralized and easy to access. After use, the pressure plate 10 can be lifted and locked in the above manner, and the silicone pad 11 can be wiped and disinfected with alcohol. By pulling out the protrusions 19 on both sides of the silicone pad 11 from the recess 20 of the support plate 9 or the pressure plate 10, it can be quickly disassembled, cleaned or replaced.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
