Detailed Implementation

[0018] Example 1: like Figure 1-6 In the present invention, a stable oscillation device for bacterial culture includes an oscillation frame 1 and a drive base 2 that cooperates with it to achieve stable transmission. The oscillation frame 1 includes a base plate 4, which is connected to a top plate 6 through multiple connecting columns 5 to form a closed and stable frame structure for supporting and fixing the limiting placement seats 3. Multiple sets of limiting placement seats 3 are evenly distributed on the base plate 4 and the top plate 6, and each set of limiting placement seats 3 is arranged vertically to ensure the vertical stability of the culture vessel after placement. The bottom of the base plate 4 is provided with symmetrically arranged U-shaped sliding grooves 8 and transmission ring grooves 13. The U-shaped sliding grooves 8 are symmetrically distributed on both sides of the bottom of the base plate 4, and the transmission ring grooves 13 are located in the central area of ​​the bottom of the base plate 4. The two cooperate with each other to form the transmission support foundation of the oscillation frame 1. The drive base 2 includes a base frame 14. The base frame 14 is symmetrically provided with a strip slide 17 that cooperates with the U-shaped annular groove 8 to achieve guided sliding and a rotating shaft 19 for providing power transmission. The rotating shaft 19 is rotatably mounted at the top center of the base frame 14 through a bearing seat. A turntable 20 is fixedly sleeved on the rotating shaft 19. The turntable 20 is provided with an eccentric transmission rod 21 that cooperates with the transmission annular groove 13 to achieve eccentric transmission. The eccentric transmission rod 21 is vertically fixed at the edge of the turntable 20, and its top end extends into the transmission annular groove 13 and can slide along the groove. The base frame 14 is fixedly connected to the drive motor 23 through a fixed seat 22. The fixed seat 22 provides positioning support for the drive motor 23. The output end of the drive motor 23 is provided with a first transmission wheel 24. The first transmission wheel 24 cooperates with a second transmission wheel 26 located at the bottom of the rotating shaft 19 through a transmission belt 25 to form a complete power transmission path.

[0019] In a preferred embodiment, the bottom of the base frame 14 is provided with a plurality of buffer pads 15, which are evenly distributed at the four corners and the middle of the bottom of the base frame 14 to absorb the impact force generated during the oscillation and reduce the overall vibration of the equipment.

[0020] In a preferred embodiment, the base plate 4 is symmetrically provided with limiting grooves 7, which are arranged along the length of the base plate 4 and cooperate with the limiting slide block 16 provided on the base frame 14 to further limit the movement trajectory of the oscillating frame 1 and prevent it from shifting in the lateral or vertical direction.

[0021] In a preferred embodiment, the U-shaped slide 8 is provided with multiple sets of first support balls 9 that cooperate with the base frame 14. The first support balls 9 are evenly embedded in the inner sidewall and bottom of the U-shaped slide 8 to reduce the sliding friction between the U-shaped slide 8 and the base frame 14.

[0022] In a preferred embodiment, the strip slide 17 is provided with multiple sets of second support balls 18 that cooperate with the U-shaped slide groove 8. The second support balls 18 are embedded in the top and sides of the strip slide 17 and work together with the first support balls 9 to improve the smoothness of the reciprocating motion of the oscillating frame 1.

[0023] In a preferred embodiment, the base plate 4 is provided with multiple sets of first fixing plates 10. The first fixing plates 10 are vertically fixed to both sides of the bottom of the base plate 4. The first fixing plates 10 are connected to the second fixing plates 12 placed on the support frame 14 through the damping structure 11. The second fixing plates 10 are fixed to the top of the base frame 14. The damping structure 11 can buffer the longitudinal vibration during the oscillation process and prevent the oscillation frame 1 from shaking up and down.

[0024] In a preferred embodiment, the limiting placement seat 3 includes a material carrier 27, which is fixedly installed at corresponding positions on the bottom plate 4 and the top plate 6. The material carrier 27 is provided with multiple sets of positioning grooves 28, the size of which is adapted to commonly used culture vessels. The inner wall of the positioning groove 28 is connected to the clamping plate 30 through multiple sets of elastic elements 29, which provide continuous clamping force. The clamping plate 30 has an arc-shaped structure that fits against the outer wall of the culture vessel. The top of the clamping plate 30 is provided with a guide arc plate 32, which is inclined outward to facilitate the quick placement and removal of the culture vessel. The side of the clamping plate 30 near the center of the material carrier 27 is provided with an anti-slip pad 31, which fits tightly against the outer wall of the culture vessel to enhance friction and prevent slippage.

[0025] Example 2: like Figure 1-6 In this invention, the working principle is as follows: the culture vessel is placed on the limiting placement seat 3, and then the drive motor 23 is started. The output end of the drive motor 23 drives the first transmission wheel 24 to rotate. The first transmission wheel 24 transmits power to the second transmission wheel 26 through the transmission belt 25, thereby driving the rotating shaft 19 fixedly connected to the second transmission wheel 26 to rotate. When the rotating shaft 19 rotates, it drives the top turntable 20 to rotate synchronously. The eccentric transmission rod 21 on the edge of the turntable 20 moves in a circular motion with the turntable 20. Since the eccentric transmission rod 21 is embedded in the transmission ring groove 13 of the oscillating frame 1, the circular motion is converted into a reciprocating thrust on the oscillating frame 1, causing the oscillating frame 1 to move in a straight reciprocating motion along the mating direction of the U-shaped slide groove 8 and the strip slide 17. During the oscillation process, the limiting slide groove 7 on the base plate 4 cooperates with the limiting slide block 16 on the base frame 14 to restrict the movement trajectory of the oscillation frame 1 and avoid lateral deviation; the first support ball 9 on the U-shaped slide groove 8 and the second support ball 18 on the strip slide block 17 roll into contact with each other, greatly reducing the frictional resistance during the reciprocating motion and ensuring smooth and stable motion. The first fixed plate 10 at the bottom of the base plate 4 is connected to the second fixed plate 12 on the base frame 14 through the damping structure 11. The damping structure 11 can absorb the longitudinal vibration energy generated by the oscillation. Together with the buffer pad 15 at the bottom of the base frame 14, it can effectively suppress the up and down shaking of the oscillating frame 1 and ensure the overall stability.

[0026] The beneficial effects of this invention are: it ensures stable reciprocating motion in a single linear direction, with uniform and stable oscillation force, avoiding the problem of solution splashing in the vessel; the limiting base corresponding to each individual vessel facilitates the quick placement and fixation of the culture vessel, and also limits and clamps it to ensure stable and continuous oscillation transmission; the overall structure of the device is simple and reasonable, the power transmission is stable and smooth, the force is uniform, and it significantly improves processing efficiency and quality.
