Description

Technical Field

[0001] This invention relates to the field of microbial culture equipment technology, and more specifically to a rotary shaker for microbial and molecular biological experiments. Background Technology

[0002] Microbiological and molecular biology experiments refer to the process of purposefully observing and studying the structures and life activities of organisms that are not easily observed under normal circumstances, using specific instruments, materials, and reagents under specific environmental conditions and through scientific methods. A rotating shaker is a multi-purpose biochemical apparatus and an indispensable laboratory piece of equipment for precise culture and preparation in research, education, and production departments of plants, biology, microorganisms, genetics, virology, environmental protection, and medicine.

[0003] Chinese patent CN113368747A discloses a rotary shaker for microbial and molecular biological experiments, comprising: a working chamber and a driving chamber, and further comprising: a swing mechanism, wherein the swing mechanism is disposed inside the working chamber and is used to drive the experimental container to reciprocate; the swing mechanism is driven by the driving mechanism to move, and the swing mechanism moves the experimental container fixed by the mounting mechanism, so that the reaction system is always in a flowing state, resulting in good performance.

[0004] However, when culturing microorganisms or molecular organisms, the microorganisms or molecular organisms in the rotating shaker rotate at the same speed. But when conducting biological experiments, it may be necessary to rotate the microorganisms or molecular organisms at different speeds to compare the differences in culturing molecular organisms at different speeds. The rotating shaker of the above patent is not convenient for shaking microorganisms at multiple speeds at the same time. Summary of the Invention

[0005] The purpose of this invention is to provide a rotary shaker for microbial and molecular biological experiments, in order to overcome the above-mentioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a rotary shaker for microbial and molecular biology experiments, comprising a fixed wheel mechanism and multiple movable wheel mechanisms, the multiple movable wheel mechanisms being arranged axially, each movable wheel mechanism including a rotating wheel, the rotating wheel being coaxial with the fixed wheel mechanism, a sliding cylinder being fixedly disposed on the surface of the rotating wheel, the rotating wheel sliding axially through the sliding cylinder, a clutch groove being formed on the surface of the rotating wheel, and a through groove being formed within the clutch groove; a retaining ring, a clutch pulley, and a tension spring, the retaining ring being coaxially connected to the clutch pulley through the tension spring, the retaining ring... The clutch pulley is coaxially engaged with the rotating wheel. A tension spring applies a force to the clutch pulley, causing it to move towards the clutch slot. After moving, the clutch pulley can be inserted into the clutch slot and rotate synchronously with it. The rotary shaking table also includes a shaking table mechanism, an eccentric ratchet mechanism, a transmission belt, and a movable housing. The clutch pulley drives the eccentric ratchet mechanism to rotate via the transmission belt. The eccentric ratchet mechanism drives the shaking table mechanism to revolve around the eccentric ratchet mechanism. The movable wheel mechanism, the shaking table mechanism, the eccentric ratchet mechanism, and the transmission belt are all housed within the movable housing, allowing the shaking table mechanism, the eccentric ratchet mechanism, and the transmission belt to move axially with the synchronous movable wheel mechanism.

[0007] Furthermore, the fixed wheel mechanism includes a fixed pulley and a fixed cylinder. The fixed pulley is fixedly connected to the fixed cylinder, and the sliding cylinder is slidably inserted into the fixed cylinder. The sliding cylinders of two adjacent movable wheel mechanisms are slidably inserted into each other, and electric push rods are provided inside the sliding cylinder and the fixed cylinder to control the lifting and lowering of the sliding cylinder inside.

[0008] Furthermore, the rotary shaking table also includes a fixed base, in which a motor is fixedly connected, and the motor is used to drive a fixed pulley to rotate.

[0009] Furthermore, the surface of the movable housing is provided with control buttons for controlling the extension and retraction of the electric actuator.

[0010] Furthermore, an abutment block is fixedly connected to the top of the fixed pulley and the rotating wheel. A pulley is rotatably provided on the top of the abutment block. The abutment block can move through the through groove on its upper side and push the clutch pulley on the upper side out of the clutch groove through the pulley.

[0011] Furthermore, the shaking mechanism has multiple components, including a shaking disc. The shaking discs of the multiple shaking mechanisms are movably connected to the movable housing and the fixed base, respectively. The surface of the shaking disc has multiple placement holes, and a pair of test tube clamps are slidably inserted into each placement hole. A compression spring is fixedly connected to the surface of the test tube clamps to apply a force that brings the test tube clamps closer to each other.

[0012] Furthermore, there are multiple eccentric ratchet mechanisms and transmission belts. Fixed pulleys and clutch pulleys are respectively connected to the eccentric ratchet mechanism via transmission belts. The eccentric ratchet mechanism includes driven pulleys, each with a different diameter. The driven pulleys are driven by the transmission belts. A driven wheel is coaxially rotatably arranged inside the driven pulley. An elastic pawl is provided on the inner wall of the driven pulley. A ratchet is coaxially fixedly connected to the surface of the driven wheel. The driven pulley drives the ratchet to rotate unidirectionally through the elastic pawl. An eccentric shaft is also included, with one end eccentrically fixedly connected to the driven wheel and the other end rotatably connected to the rocker disc.

[0013] 1. Compared with the prior art, the present invention provides a rotary shaker for microbial and molecular biological experiments. By setting a fixed wheel mechanism and multiple movable wheel mechanisms, a shaker mechanism, an eccentric ratchet mechanism, and a transmission belt, and with each eccentric ratchet mechanism having a different outer diameter, the fixed wheel mechanism and the movable wheel mechanism can drive the eccentric ratchet mechanism connected to them to rotate at different speeds through the transmission belt, thereby driving each shaker mechanism to revolve at different speeds, thus realizing the simultaneous shaking of culture test tubes at different speeds.

[0014] 2. Compared with the prior art, the present invention provides a rotary shaker for microbial and molecular biology experiments. The rotating shell and its internal mechanisms—including the movable wheel mechanism, shaker mechanism, eccentric wheel mechanism, and transmission belt—are height-adjustable. When raised, the clutch pulley moves away from the pulley and abutment block below it, and under the action of a tension spring, it engages with the clutch groove, making close contact and increasing friction. This allows the rotating wheel to drive the clutch pulley to rotate synchronously. This allows the unused shaker mechanism, movable wheel mechanism, shaker mechanism, eccentric ratchet mechanism, and transmission belt to be lowered and retracted. The lowered shaker mechanism is unpowered, saving space and energy. Furthermore, it can be raised for easy insertion of test tubes for culturing organisms, and the power allows the test tubes to be shaken, making it more convenient and practical.

[0026] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; and they may refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] Please see Figures 1-8 A rotary shaker for microbial and molecular biology experiments includes a fixed wheel mechanism and multiple movable wheel mechanisms. The multiple movable wheel mechanisms are arranged axially. Each movable wheel mechanism includes a rotating wheel 41, which is coaxial with the fixed wheel mechanism. A sliding cylinder 42 is fixedly provided on the surface of the rotating wheel 41, and the rotating wheel 41 slides axially through the sliding cylinder 42. A clutch groove 43 is formed on the surface of the rotating wheel 41, and a through groove 44 is formed in the clutch groove 43. A locking ring 45, a clutch pulley 46, and a tension spring 47 are also included. The locking ring 45 is coaxially connected to the clutch pulley 46 through the tension spring 47. The locking ring 45 and the rotating wheel 41 are coaxially locked and rotated. The tension spring 47 applies a force to the clutch pulley 46 to move towards the clutch groove 43. After the clutch pulley 46 moves, it can insert into the clutch groove 43 and rotate synchronously with it, so that the clutch pulley 46 can be inserted into the clutch groove 43 and make close contact with it to increase the friction force, so that the rotating wheel 41 can drive the clutch pulley 46 to rotate synchronously.

[0030] The rotary shaking table also includes a shaking table mechanism, an eccentric ratchet mechanism, a transmission belt 61, and a movable housing 31. The clutch pulley 46 drives the eccentric ratchet mechanism to rotate via the transmission belt 61. The eccentric ratchet mechanism drives the shaking table mechanism to revolve around the eccentric ratchet mechanism. The movable wheel mechanism, the shaking table mechanism, the eccentric ratchet mechanism, and the transmission belt 61 are all housed within the movable housing 31, allowing the shaking table mechanism, the eccentric ratchet mechanism, and the transmission belt 61 to move axially with the synchronous movable wheel mechanism.

[0031] The fixed wheel mechanism includes a fixed pulley 21 and a fixed cylinder 22. The fixed pulley 21 is fixedly connected to the fixed cylinder 22, and the sliding cylinder 42 is slidably inserted into the fixed cylinder 22. The sliding cylinders 42 of two adjacent movable wheel mechanisms are slidably inserted into each other, and electric push rods are provided inside the sliding cylinder 42 and the fixed cylinder 22 to control the lifting and lowering of the sliding cylinder 42 inside.

[0032] A control button 32 is provided on the surface of the movable housing 31 for controlling the extension and retraction of the electric actuator. Preferably, an electric actuator is also fixedly connected to the bottom of each movable housing 31. The extension and retraction of the electric actuator can be controlled by pressing the control button 32, so that the movable housing 31 connected to the control button 32 and its internal movable wheel mechanism, shaking mechanism, eccentric wheel mechanism, and transmission belt 61 are raised. This raises the movable housing 31 where the shaking mechanism for shaking the culture tubes is located, making it easier to insert the culture tubes and preventing interference caused by inserting the culture tubes into other revolving shaking mechanisms.

[0033] A stop block 51 is fixedly connected to the top of the fixed pulley 21 and the rotating wheel 41. A pulley 52 is rotatably mounted on the top of the stop block 51, with the axis of the pulley 52 pointing towards the axis of the fixed pulley 21 and the rotating wheel 41. The stop block 51 can move through the through groove 44 on its upper side, and the upper clutch pulley 46 is pushed out of the clutch groove 43 by the pulley 52. ​​The pulley 52 is used to reduce the friction when it contacts and rotates with the clutch pulley 46. When the electric actuator drives the movable housing 31 and its internal movable wheel mechanism, rocking bed mechanism, eccentric wheel mechanism and transmission belt 61 to rise, the clutch pulley 46 moves away from the pulley 52 and the stop block 51 on its lower side, and is inserted into the clutch groove 43 under the action of the tension spring 47.

[0034] The rotary shaking table also includes a fixed base 11, within which a motor 12 is fixedly connected. The motor 12 drives a fixed pulley 21 to rotate, which in turn drives rotating wheels 41 that are slidably connected to and interlocked with each other via a fixed cylinder 22. The rotation of the fixed pulley 21 and the rotating wheels 41 of each raised movable wheel mechanism are all driven by a driven pulley 81 connected to it via a transmission belt 61.

[0035] There are multiple eccentric ratchet mechanisms and transmission belts 61. Fixed pulleys 21 and clutch pulleys 46 are respectively connected to the eccentric ratchet mechanism via transmission belts 61. The eccentric ratchet mechanism includes driven pulleys 81, and each driven pulley 81 has a different diameter. The fixed pulleys 21 and each clutch pulley 46 have the same diameter, so that the fixed pulleys 21 and clutch pulleys 46 have the same diameter and drive each driven pulley 81 to rotate at different speeds via transmission belts 61. That is, each shaking disc 71 revolves at a different speed, thereby realizing the simultaneous shaking of the culture test tube at different speeds.

[0036] Driven pulley 81 is driven by drive belt 61. Driven pulley 82 is coaxially rotatably arranged inside driven pulley 81. Elastic pawl 84 is provided on the inner wall of driven pulley 81. Ratchet 85 is coaxially fixedly connected to the surface of driven pulley 82. Driven pulley 81 drives ratchet 85 to rotate in one direction through elastic pawl 84. Eccentric shaft 83 is eccentrically fixedly connected to driven pulley 82 at one end and rotatably connected to rocking disk 71 at the other end. When the eccentric wheel mechanism is not raised, only the fixed pulley 21 can drive the driven pulley 81 at the bottom, which is connected to it, to rotate via the transmission belt 61. This allows the culture tube containing microorganisms or molecular organisms to be inserted from between the top and bottom test tube clamps 73, ensuring the culture tube is held in place by the bottom clamps 73. The driven pulley 81 at the bottom can then drive the ratchet 85 to rotate via the elastic pawl 84, thereby causing the driven wheel 82, which is fixedly connected to the ratchet 85, and the eccentric shaft 83 fixedly connected to it to rotate. The eccentric shaft 83 causes the bottom rocking disc 71 to rotate eccentrically about the axis of the driven wheel 82 of the eccentric ratchet mechanism, thereby causing the culture tubes in the test tube clamps 73 inserted therein to shake. When the culture tubes shake, they will cause the other test tube clamps 73 and the rocking discs 71 they pass through to shake as well, thereby causing the driven wheel 82, which is rotatably connected to these rocking discs 71 through the eccentric shaft 83, to rotate. Due to the structure of the ratchet 85 and the elastic pawl 84, the rotation of the driven wheel 82 at this time will not drive the driven belt pulley 81 to rotate, thus reducing energy loss.

[0037] There are multiple shaking mechanisms, including shaking discs 71. The shaking discs 71 of the multiple shaking mechanisms are movably connected to the movable housing 31 and the fixed base 11 respectively. Multiple placement holes 72 are opened on the surface of the shaking discs 71. A pair of test tube clamps 73 are slidably inserted into each placement hole 72. A compression spring is fixedly connected to the surface of the test tube clamps 73 to apply a force that brings the test tube clamps 73 closer to each other, so as to clamp the culture test tube inserted between the pair of test tube clamps 73.

[0038] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
