Description

Technical Field

[0001] The present invention relates to a self-locking quick-release structure and a uniform force field shaker. The structure is mounted on a uniform force field shaker, securely securing a disc on the shaker and allowing for quick removal and replacement. The structure belongs to the technical field of shaker equipment. In particular, the structure utilizes a self-locking double-sided clamping structure to squeeze and secure connecting pieces on both sides of the disc's bottom, releasing and removing them. Background Art

[0002] Cell culture medium contains various components such as nutrients, metabolites and cells themselves. During the cell culture process, cells will be suspended or aggregated in the liquid culture medium, resulting in insufficient cell metabolism or mutual interference, affecting the experimental results. Through oscillation, cells can be evenly dispersed to prevent their aggregation. At the same time, oscillation can also accelerate the diffusion and mixing of nutrient molecules and cells in the culture medium, thereby improving the culture effect. A shaker is an important oscillation device that uses mechanical vibration to achieve reciprocating motion of the sample in a fixed direction to achieve oscillation of the culture medium. However, traditional shakers usually provide unidirectional or bidirectional (such as front and back, left and right) oscillation modes with adjustable amplitude and speed. Multi-dimensional oscillation cannot be achieved, resulting in uneven mixing or dispersion, especially for liquids with higher viscosity involved in the experiment. The dispersion effect is poor and the uniformity is low.

[0003] Publication No. CN221918118U discloses a pull-out oscillation assembly for a rocking table, comprising a lower plate and an upper plate, characterized in that: an active rocking shaft assembly is fixedly arranged at the middle position of the upper portion of the lower plate, and a slave rocking shaft assembly is fixedly arranged at the positions of the four corners of the upper portion of the lower plate, the lower portion of the upper plate is fixedly connected to the active rocking shaft assembly and the slave rocking shaft assembly, a lower rail is fixedly arranged at the upper portion of the upper plate, a drawer is arranged above the upper plate, an upper rail is fixedly arranged at the lower portion of the drawer, the upper rail is slidably connected to the lower rail, a rocking plate is fixedly arranged at the upper portion of the drawer, and a spring clip is fixedly arranged at the upper portion of the rocking plate; the rocking table provides a unidirectional oscillation mode, and the amplitude and speed can be adjusted, and multi-dimensional oscillation cannot be achieved, resulting in uneven mixing or dispersion, especially for liquids with higher viscosity involved in the experiment, the dispersion effect is poor and the uniformity is low.

[0004] To address these issues, the applicant filed a separate Chinese invention patent application titled "A Uniform Force Field Shaker." The invention utilizes a motor to drive an arc-shaped chute, driving a circular disc to achieve dynamic cross-directional motion. This in turn applies multi-directional oscillating forces to form a uniform force field for efficient dispersion of cell culture fluid. However, the shaker is connected to the center of the disc only via a connecting post. During high-speed rotation, the connecting post cannot provide stable support for the disc. Furthermore, the disc and connecting post are connected by bolts or welds, making them difficult to disassemble and inconvenient for replacing discs of different models. Summary of the Invention

DETAILED DESCRIPTION Example 1

[0012] The present invention provides a self-locking quick-release structure and a uniform force field shaker as follows: the present invention provides a self-locking quick-release structure comprising a first connecting rod (20), a first extrusion strip (21), two L-shaped connectors (22), two connecting pieces (23), a first U-shaped connector (24), a cylinder (25), a second U-shaped connector (26), a second connecting rod (27), a second extrusion strip (28), and two square grooves (29), wherein the cylinder (25) is placed on an end of the connecting column (3) away from the slider (17), and the first U-shaped connector (24) is placed on the cylinder (25). Preferably, the first U-shaped connecting member (24) is provided with a through hole for circumventing the piston rod of the cylinder (25). Two L-shaped connectors (22) are respectively placed on both sides of the two vertical sections of the first U-shaped connector (24), and a square groove (29) is opened on the horizontal section of the L-shaped connector (22). Preferably, a layer of silicone gasket is embedded inside the square groove (29). The middle portion of the second U-shaped connecting member (26) is connected to the piston rod of the cylinder (25), one end of the first connecting rod (20) is rotatably connected to the end of the second U-shaped connecting member (26), the first extruded strip (21) passes through a through hole on a vertical section of the first U-shaped connecting member (24), one end of the first extruded strip (21) is rotatably connected to the other end of the first connecting rod (20), one end of the second connecting rod (27) is rotatably connected to the end of the second U-shaped connecting member (26), the second extruded strip (28) passes through a through hole on another vertical section of the first U-shaped connecting member (24), one end of the second extruded strip (28) is rotatably connected to the other end of the second connecting rod (27), Preferably, the area of the other end surface of the first extruded strip (21) is larger than the area of the remaining portion of the first extruded strip (21), and the remaining portion of the first extruded strip (21) is linear. Preferably, the area of the other end surface of the second extruded strip (28) is larger than the area of the remaining portion of the second extruded strip (28), and the remaining portion of the second extruded strip (28) is linear. Preferably, a wear-resistant and anti-slip coating is applied on the other end surface of the first extruded strip (21) and the second extruded strip (28). One end of the two connecting pieces (23) is symmetrically placed on the disk (2) of the uniform force field shaker, and the other end of the two connecting pieces (23) passes through the two square slots (29) respectively. Alternatively, the connecting piece (23) is designed as a T-shaped structure, the horizontal section of the connecting piece (23) is placed on the upper surface of the disc (2), and the vertical section of the connecting piece (23) passes through the through hole on the disc (2). The other end of the first extruded strip (21) cooperates with a vertical section of an L-shaped connector to extrude and fix a connecting piece (23), and fixes the connecting piece (23) in a square groove (29); the other end of the second extruded strip (28) cooperates with another vertical section of an L-shaped connector to extrude and fix another connecting piece (23), and fixes the other connecting piece (23) in another square groove (29). When in use, first insert the connecting piece (23) at the bottom of the disc (2) into the square groove (29) of the L-shaped connecting piece (22), and the piston rod of the cylinder (25) pushes the second U-shaped connecting piece (26) to rise, pushing the first connecting rod (20) and the second connecting rod (27) to move to both sides, thereby pushing the first extrusion strip (21) and the second extrusion strip (28) to move toward the L-shaped connecting piece (22). The first extrusion strip (21) and the second extrusion strip (28) cooperate with the L-shaped connecting piece (22) to squeeze and fix the connecting piece (23), thereby fixing the disc (2). When the disc (2) needs to be disassembled, the piston rod of the cylinder (25) contracts, and the first extrusion strip (21) and the second extrusion strip (28) release the pressure on the connecting piece (23), so that the connecting piece (23) can be easily pulled out from the square groove (29) to disassemble the disc (2).

[0013] The design of embedding a layer of silicone gasket inside the square groove (29) can increase the friction between the connecting piece (23), improve the stability of the connection piece (23), and reduce the impact on the connecting piece (23) during installation and removal.

The area of the other end surface of the second extruded strip (28) is larger than the area of the remaining portion of the second extruded strip (28), and the remaining portion of the second extruded strip (28) is linear. This design can increase the contact area with the connecting piece (23) without affecting the movement of the first extruded strip (21) and the second extruded strip (28), evenly disperse the pressure, avoid local stress concentration, and thus prevent the connecting piece (23) from being damaged due to overpressure. A wear-resistant and anti-slip coating is applied on the other end surfaces of the first extrusion strip (21) and the second extrusion strip (28) to increase the friction between the first extrusion strip (21) and the connecting piece (23) and improve the extrusion fixing effect. The connecting piece (23) is designed as a T-shaped structure, the horizontal section of the connecting piece (23) is placed on the upper surface of the disc (2), and the vertical section of the connecting piece (23) passes through the through hole on the disc (2), which can better engage the disc (2) and effectively prevent the disc (2) from loosening during high-speed rotation or vibration, thereby ensuring connection stability. The purpose of being able to squeeze, fix, release and disassemble the connecting pieces on both sides of the bottom of the disc is achieved through the self-locking double-sided clamping structure.

Preferably, the curvature of the arc-shaped piece (10) matches the curvature of the cross slot (14) on the sphere (13), and the contact surface of the arc-shaped piece (10) is processed by a mirror polishing process.

Preferably, the first arc-shaped chute (4) is parallel to the other chute of the cross chute (14), and the second arc-shaped chute (9) is parallel to one chute of the cross chute (14). The container fixing support device is composed of a tube hole (1), a disc (2), and a connecting column (3). One end of the connecting column (3) passes through the first arc-shaped chute (4) and the second arc-shaped chute (9) in sequence and is placed on the slider (17). The disc (2) is placed on the other end of the connecting column (3). A plurality of tube holes (1) are evenly opened on the disc (2).

When in use, first place the sample to be separated in the test tube, fix the test tube in the tube hole (1), and the second motor (16) drives the second arc-shaped chute (9) and the connecting column (3) to rotate back and forth, thereby driving the disc (2) and the test tube on the disc (2) to oscillate back and forth along the trajectory of the first arc-shaped chute (4). The first motor (5) drives the first arc-shaped chute (4) to rotate back and forth, so that the slider (17) drives the cross chute (14) on the sphere (13) to move along the guide trajectory of the arc-shaped piece (10). The connecting column (3) and the disc (2) are driven to reciprocate and slide, and at the same time, the connecting column (3) and the disc (2) are driven to oscillate back and forth along the trajectory of the second arc-shaped chute (9).

It can absorb and disperse the vibration energy generated by the equipment during operation step by step, thereby enhancing the shock-absorbing effect and further improving the stability of the equipment operation. The column (11) adopts a trapezoidal cross-section design. The cross section of the column (11) is an isosceles trapezoidal structure. The design of being small at the top and large at the bottom can enhance its bending strength and stability, better disperse the stress transmitted by the arc-shaped piece (10), and avoid deformation or fracture caused by local force concentration. The curvature of the arc-shaped piece (10) matches the curvature of the cross-shaped groove (14) on the sphere (13), and the contact surface of the arc-shaped piece (10) is designed to be treated with a mirror polishing process, so that the arc-shaped piece (10) can smoothly fit the cross-shaped groove (14) when the sphere (13) rotates, thereby reducing friction and improving sliding smoothness; Elastic rubber buffer gaskets are provided on the inner walls of both ends of the first arc-shaped chute (4) and the second arc-shaped chute (9), which can provide a certain buffer when the connecting column (3) slides in the first arc-shaped chute (4) and the second arc-shaped chute (9) to the end, thereby avoiding hard collision and ensuring the smooth operation of the device; The disc (2) is made of lightweight alloy material and has a wear-resistant coating on its surface, which can improve its durability and impact resistance, reduce the overall weight of the device, and optimize the performance of the device. The tube hole (1) is embedded with an elastic clamping ring made of polymer material, which can provide a stable clamping force to prevent the test tube from falling off during the multi-directional oscillation process. The purpose is to use the motor to drive the arc chute to move, drive the disc to achieve dynamic movement in the cross direction, and then apply multi-directional oscillating force to form a uniform force field for efficient dispersion.
