Technical Field
[0001] This utility model relates to the field of experimental equipment technology, specifically to a non-slip and non-tipping conical flask oscillation platform. Background Technology
[0002] A shaker, also known as a oscillator, is a common piece of equipment used in biological, chemical, and medical laboratories for shaking culture, mixing, and dissolving operations. Its core component is a shaking platform for placing containers such as conical flasks. It is primarily used to increase the dissolved oxygen content in the culture medium, promoting the full binding of yeast cells or reaction substrates. It is suitable for experiments such as bacterial culture, fermentation, and enzyme reactions. Currently, most common platforms are flat or equipped with only simple spring clamps or stops. The platform surface is smooth, and the conical flask is prone to sliding during high-speed oscillation or sudden start and stop, which can lead to flask collision, breakage, or sample spillage. Existing spring clamps usually only fix the neck of the conical flask. For conical flasks with a high center of gravity, they may still tip over due to inertia during oscillation, resulting in poor anti-slip and anti-tipping capabilities. In addition, different laboratories use conical flasks with different specifications, and fixed clamps require cumbersome adjustments or replacement of the entire clamp module when changing flask types, which is not very versatile. Utility Model Content
[0003] The purpose of this invention is to provide a non-slip and anti-tipping conical bottle oscillation platform to solve the problems in the background art, such as the smooth surface of the platform, the easy slippage of the conical bottle, the existing spring clamps usually only fix the neck of the bottle, the poor anti-slip and anti-tipping ability, and the need for cumbersome adjustment or replacement of the entire clamp module when changing bottle types, resulting in insufficient versatility.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a non-slip and anti-tipping conical flask oscillation platform, comprising a base and a conical flask, wherein a mounting plate is provided on the top of the base, an oscillation assembly is provided on the front side of the mounting plate, and a fixing assembly is provided on the outside of the oscillation assembly; the fixing assembly comprises a platform and a non-slip placement plate, wherein multiple equidistantly distributed guide sleeves are fixedly connected to the top of the platform, the non-slip placement plate is positioned above the guide sleeves, and a guide post is slidably connected to the bottom of the non-slip placement plate within the guide sleeves; the conical flask is positioned on the top of the non-slip placement plate, and a lifting mechanism is provided between the platform and the non-slip placement plate; multiple connecting rods are equidistantly hinged in a ring at the top of the platform, and a bent end is provided at one end of each connecting rod near the platform, located below the non-slip placement plate; a roller is rotatably connected to the end of the bent end; tension springs are movably installed on the outer side walls of each connecting rod, and the other end of the tension spring is positioned at the top edge of the platform; a clamping block is movably hinged to the upper end of each connecting rod.
[0005] Preferably, the lifting mechanism includes two lead screws that are horizontally rotatably mounted on the top of the platform and arranged symmetrically from left to right. A servo motor is fixedly mounted at the center of the bottom of the platform. A transmission rod located between the two lead screws is fixedly connected to the external output shaft of the servo motor. A bevel gear is provided at the upper end of the transmission rod and at the adjacent end of the two lead screws for meshing transmission. A slider is threaded to the external of both lead screws. A connecting rod is movably hinged to the top of the slider. The other end of the connecting rod is movably hinged to the bottom of the anti-slip placement plate.

The clamping block is attached to the outer wall of the conical bottle to stably clamp conical bottles with different centers of gravity. Combined with the anti-slip treatment on the surface of the anti-slip placement plate, the fixing stability is improved and the anti-slip and anti-tipping ability is enhanced. 2. By precisely controlling the lifting height of the anti-slip placement plate, the rotation angle of the connecting rod can be adjusted, thereby flexibly adjusting the clamping position of the clamping block. This allows for precise and stable clamping of conical flasks of different sizes, preventing tipping due to unstable clamping caused by size differences during vibration. This effectively improves the compatibility and applicability of conical flasks of different specifications. Attached Figure Description

[0014] 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.
[0015] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6This utility model provides a technical solution: a non-slip and anti-tipping conical flask oscillation platform, including a base 1 and a conical flask 2. A mounting plate 3 is provided on the top of the base 1, and an oscillation assembly 4 is provided on the front side of the mounting plate 3. A fixing assembly 5 is provided outside the oscillation assembly 4. The fixing assembly 5 includes a platform 51 and a non-slip placement plate 53. Multiple equidistantly distributed guide sleeves 52 are fixedly connected to the top of the platform 51. The non-slip placement plate 53 is positioned above the guide sleeves 52, and a guide post slidably connected within the guide sleeves 52 is provided at the bottom of the non-slip placement plate 53. The conical flask 2 is positioned on the top of the non-slip placement plate 53. A lifting mechanism 54 is provided between the platform 51 and the non-slip placement plate 53. Multiple connecting rods 55 are equidistantly hinged in a ring at the top of the platform 51. One end of each connecting rod 55 near the platform 51 is located on the non-slip placement plate 53. The bent end 56 below 3 is rotatably connected to a roller 57. Multiple connecting rods 55 are movably mounted on their outer walls with tension springs 58. The other end of the tension springs 58 is located at the top edge of the platform 51. The upper end of the connecting rod 55 is movably hinged with a clamping block 59. The conical bottle 2 is placed on the anti-slip placement plate 53. The lifting mechanism 54 is controlled to drive the anti-slip placement plate 53 to move down. The bottom guide rod of the anti-slip placement plate 53 slides in the guide sleeve 52 to provide guidance. As the anti-slip placement plate 53 moves down, the roller 57 is pressed down, which drives the bent end 56 to drive the connecting rod 55 to rotate along the hinge point with the platform 51 towards the conical bottle 2 and stretch the tension springs 58. The clamping block 59 fits against the outer wall of the conical bottle 2 and can stably clamp the conical bottle 2 with different centers of gravity. Combined with the anti-slip treatment on the surface of the anti-slip placement plate 53, the fixation stability is improved and the anti-slip and anti-tipping ability is improved.
[0016] When it is necessary to release the conical flask 2, the lifting mechanism 54 pushes the anti-slip placement plate 53 upward, the tension spring 58 returns to its original position and retracts, causing the connecting rod 55 to rotate in the opposite direction along the hinge with the platform 51, and the clamping block 59 disengages from the outer wall of the conical flask 2, making it easy to pick up and put down the conical flask 2. By flexibly controlling the lifting height of the anti-slip placement plate 53, the rotation angle of the connecting rod 55 can be adjusted, and the clamping position of the clamping block 59 can be flexibly adjusted to adapt to conical flasks 2 of different sizes. Through adjustment, a precise and stable clamping effect can be obtained, avoiding the situation of tipping over due to unstable clamping caused by size differences during the vibration process, effectively improving the compatibility and applicability of conical flasks 2 of different specifications.
[0017] The lifting mechanism 54 includes two lead screws 541 horizontally rotatably mounted on the top of the platform 51 and symmetrically arranged. A servo motor 544 (NEMA23 model) is fixedly mounted in the center of the bottom of the platform 51. A transmission rod 542 located between the two lead screws 541 is fixedly connected to the external output shaft of the servo motor 544. A bevel gear 543 for meshing transmission is provided at the upper end of the transmission rod 542 and the adjacent end of the two lead screws 541. A slider 545 is threaded to the external of both lead screws 541. A connecting rod 546 is movably hinged to the top of the slider 545. The other end of the connecting rod 546 is movably hinged to the bottom of the anti-slip plate 53. When the servo motor 544 is started... When the output shaft drives the transmission rod 542 to rotate, the two lead screws 541 rotate synchronously through the meshing transmission of the bevel gear 543. When the lead screw 541 rotates, the two sliders 545 connected by the external thread move towards or away from each other along the axial direction of the two lead screws 541, thereby driving the lower end of the connecting rod 546 to move accordingly. Since the upper end of the connecting rod 546 is hinged to the bottom of the anti-slip plate 53, the movement of the slider 545 will change the angle between the connecting rod 546 and the horizontal direction, thereby realizing the smooth lifting and lowering of the anti-slip plate 53. It can accurately control the lifting height of the anti-slip plate 53, ensuring the stability and reliability of the clamping process. The driving method of the servo motor 544 also ensures the convenience and automation of operation.
[0018] The top of the anti-slip placement plate 53 is provided with anti-slip texture, which is distributed in an interlaced grid pattern. This can effectively increase the friction between the bottom of the conical bottle 2 and the surface of the anti-slip placement plate 53, prevent the conical bottle 2 from sliding due to vibration during the oscillation process, enhance the fixing effect on the conical bottle, and make it safer and more reliable during operation.
[0019] The guide sleeves 52 are located at the top of the platform 51 and are distributed in a ring at equal intervals. The rollers 57 are set against the bottom of the anti-slip placement plate 53. When the anti-slip placement plate 53 is raised or lowered, the rollers 57 will roll along the bottom of the anti-slip placement plate 53, which will drive the bent end 56 below the connecting rod 55 to rotate and change the angle to clamp the conical bottle 2. The ring-shaped guide sleeves 52 are distributed through the bottom of the platform 51, which can ensure that the anti-slip placement plate 53 always remains horizontal during the raising and lowering process, prevent it from tilting or shifting, and improve the stability of the entire device.
[0020] The inner wall of the clamping block 59 is arc-shaped to fit the conical flask 2, allowing it to fit tightly against the outer wall of the conical flask 2. This increases the contact area and provides a more stable clamping force, preventing the conical flask 2 from shifting due to shaking during oscillation. When the anti-slip plate 53 rises and falls, causing the connecting rod 55 to rotate, the clamping block 59 will adjust its position synchronously with the angle change of the connecting rod 55, always maintaining a close fit with the outer wall of the conical flask 2. This further enhances the fixing effect on the conical flask 2, preventing it from tipping over during high-frequency oscillation and ensuring the smooth progress of the experiment.
[0021] Please see Figure 1 , Figure 4 and Figure 5 The oscillation assembly 4 includes a turntable 41 rotatably mounted on the front side of the mounting plate 3. The rear side of the turntable 41 passes through the mounting plate 3. Guide rails 42, symmetrically arranged on the left and right sides of the turntable 41, are fixedly mounted on the front side of the mounting plate 3. An "L"-shaped carriage 43 is slidably mounted on the outside of the guide rails 42. A fixing assembly 5 is fixedly mounted on the top of the carriage 43. A limiting plate 44 is fixedly connected between the carriages 43. A horizontally arranged straight slot hole 45 is opened inside the limiting plate 44. A bolt 46 located in the straight slot hole 45 is movably mounted on the front side of the turntable 41. A servo motor 47 is fixedly mounted on the rear side of the mounting plate 3. The output shaft of the servo motor 47 is connected to the turntable. A meshing bevel gear 48 is fixedly installed on the rear side of 41. The servo motor 47 can be model 8MSA3S.E2-K5. When the servo motor 47 is started, the servo motor 47 transmits power to the turntable 41 through the bevel gear 48, causing the turntable 41 to rotate. When the turntable 41 rotates, it drives the bolt 46 to rotate. The bolt 46 is in the straight slot hole 45. When the bolt 46 makes a circular motion around the axis of the turntable 41, it slides in the straight slot hole 45, thereby pushing the limiting plate 44 and the slide 43 connected to the limiting plate 44 to slide up and down along the outside of the guide rail 42, driving the fixed component 5 and the conical bottle 2 on it to move, realizing the oscillation of the conical bottle 2.
[0022] Multiple threaded holes, adapted to fit the bolts 46, are arranged radially at equal intervals on the front side of the turntable 41. The bolts 46 are threaded into the threaded holes. By selecting different positions of the threaded holes to install the bolts 46, the distance between the bolts 46 and the axis of the turntable 41 can be changed, that is, the radius of the circular motion of the bolts 46 can be adjusted. When the bolts 46 are installed in the threaded holes closer to the axis of the turntable 41, their sliding stroke in the straight slot hole 45 is shorter, resulting in a smaller up-and-down reciprocating motion amplitude of the slide 43 and the fixing component 5, and the oscillation amplitude of the conical flask 2 is reduced accordingly. When the bolts 46 are installed in the threaded holes farther from the axis of the turntable 41, the radius of the circular motion of the bolts 46 increases, and the sliding stroke in the straight slot hole 45 becomes longer, which increases the reciprocating sliding amplitude of the slide 43, thereby increasing the oscillation amplitude of the conical flask 2. This achieves the adjustment of the oscillation amplitude of the conical flask 2 and meets the requirements of oscillation intensity under different experimental scenarios.
[0023] Working principle: In use, the conical bottle 2 is placed on the anti-slip plate 53, and the servo motor 544 drives the transmission rod 542 to rotate. The bevel gear 543 outside the transmission rod 542 meshes with the bevel gears 543 at the ends of the left and right lead screws 541 respectively, thereby driving the left and right lead screws 541 to rotate synchronously. The rotation of the lead screws 541 drives the sliders 545 on both sides to slide towards each other, driving the connecting rod 546 to pull the anti-slip plate. As the anti-slip plate 53 moves downward, the bottom guide rod of the anti-slip plate 53 slides within the guide sleeve 52 to provide guidance. As the anti-slip plate 53 moves downward, the roller 57 is pressed down, driving the bent end 56 to rotate the connecting rod 55 along the hinge point with the top of the platform 51 towards the conical bottle 2. At the same time, the tension spring 58 is stretched, and the clamping block 59 is attached to the outer wall of the conical bottle 2 for clamping, thereby ensuring the stable fixation of the conical bottle 2. Combined with the anti-slip treatment on the surface of the anti-slip plate 53, the anti-slip and anti-tipping performance is improved. Subsequently, the servo motor 47 is turned on by control. The servo motor 47 and the turntable 41 transmit power through the bevel gear 48, thereby causing the turntable 41 to rotate. When the turntable 41 rotates, it drives the bolt 46 to rotate. The bolt 46 is located in the straight slot hole 45. When the bolt 46 moves in a circle around the axis of the turntable 41, it slides in the straight slot hole 45, which drives the limiting plate 44 and the slide 43 connected to the limiting plate 44 to slide up and down along the guide rail 42. This drives the fixed component 5 and the conical bottle 2 on the fixed component 5 to move and realize the oscillation of the conical bottle 2. The above is the working process of the whole device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.
[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.
