[0024] This embodiment provides an automatic centrifuge homing device, such as... Figure 1 As shown, it includes: a support assembly 1, a sample placement component 2, a rotating component 3, and a return component 4; the sample placement component 2 is connected to the support assembly 1 via the rotating component 3; the return component 4 is connected to both the rotating component 3 and the support assembly 1; the return component 4 is used to drive the rotating component 3 and the sample placement component 2 back to their initial positions when the centrifuge has finished working.
[0025] For reference, such as Figure 1As shown, the sample placement component 2 can be a square structure, which in the art can be called a sample basket or sample hanging basket, and can be used to place samples to be centrifuged. The rotating component 3 can be a rotating shaft, and the returning component 4 can be a return spring, such as a torsion spring.
[0026] For reference, such as Figure 2 As shown, the rotating component 3 includes a first end 31 and a second end 32; the first end 31 of the rotating component 3 is connected to the side wall of the sample placement component 2, and the second end 32 of the rotating component 3 is rotatably connected to the support assembly 1; one end of the return component 4 is connected to the second end 32 of the rotating component 3, and the other end of the return component 4 is connected to the support assembly 1.
[0027] In specific applications, taking a torsion spring as an example, the spring body of the torsion spring can be sleeved on the second end 32 of the rotating component 3, such as... Figure 1 As shown, the torsion spring is directly sleeved on the outer wall of the rotating shaft. One end of the torsion spring is fixedly connected to the rotating shaft, and as the rotating shaft rotates, the other end of the torsion spring is fixed to the side wall of the support assembly 1.
[0028] In one possible implementation, such as Figure 2 As shown, the support component 1 is provided with a protective cover 5, which is rotatably connected to the second end 32 of the rotating component 3, and part of the body of the return component 4 is located inside the protective cover 5.
[0029] For reference, such as Figure 2 and Figure 3 As shown, the protective cover 5 has a clearance groove 51. The protective cover 5 is rotatably connected to the second end 32 of the rotating component 3. Taking the torsion spring as an example, part of the torsion spring body of the return component 4 is located inside the protective cover 5, and the end of the torsion spring connected to the support assembly 1 passes through the clearance groove 51. The protective cover 5 covers part of the return component 4, providing it with a closed space, effectively preventing the return component 4 from directly contacting dust, debris, etc., preventing these external factors from damaging the return component 4, thereby ensuring the normal operation of the return component 4 and extending its service life.
[0030] In one possible implementation, such as Figure 4 As shown, the support assembly 1 includes a first support member 11 and a second support member 12, which are disposed opposite to each other; the sample placement member 2 is disposed between the first support member 11 and the second support member 12, one side of the sample placement member 2 is connected to the first support member 11 through a rotating member 3, and the other side of the sample placement member 2 is connected to the second support member 12 through another rotating member 3.
[0031] For reference, prepare two rotating components 3, which are typically rotating shafts. Connect the first end 31 of one rotating component 3 to the side wall of the sample placement component 2. For example, the side wall of the sample placement component 2 has a through hole, and the first end 31 of the rotating component 3 is connected to the through hole. Rotate the second end 32 of the rotating component 3 to the first support component 11, which can be achieved by installing a bearing. Select a bearing with a suitable inner and outer diameter, install it in the bearing housing of the first support component 11, and then insert the second end 32 of the rotating shaft into the inner ring of the bearing, so that the rotating component 3 can rotate on the first support component 11.
[0032] Using the same method, connect another rotating component 3 to the other side of the sample placement component 2 and the second support component 12. The installation on both sides must be symmetrical to ensure that the sample placement component 2 does not tilt or jam during rotation, resulting in smoother operation.
[0033] In one possible implementation, the return element 4 is provided on both sides of the rotating element 3 of the sample placement member 2. The return element 4 provided on both sides can provide a more uniform, stable, and effective return force. For example, a torsion spring, acting simultaneously from both sides, can make the sample placement member 2 return to its initial position more accurately and quickly.
[0034] In practical applications, after the centrifuge is turned on and enters its working state, it generates high-speed centrifugal force. At this time, the sample placement component 2 (such as a sample basket or sample hanging basket), which is connected to the support assembly 1 through the rotating component 3, will rotate around the rotating component 3 at a certain angle under the action of centrifugal force, deviating from its initial position. Taking a torsion spring as the return component 4 as an example, the spring body of the torsion spring is sleeved on the outer wall of the second end 32 of the rotating component 3, and one end is fixedly connected to the rotating shaft. When the rotating shaft rotates with the sample placement component 2, the torsion spring will undergo torsional deformation, thereby storing elastic potential energy. When the centrifuge stops working, the centrifugal force gradually disappears. At this time, due to the previously stored elastic potential energy, the torsion spring will generate an elastic restoring force. Since one end of the torsion spring is fixed on the rotating shaft and the other end is fixed to the side wall of the support assembly 1, the elastic restoring force of the torsion spring drives the rotating shaft to rotate in the opposite direction. Because the first end 31 of the rotating component 3 is connected to the sample placement component 2, the reverse rotation of the rotating shaft will drive the sample placement component 2 to rotate in the opposite direction as well. Finally, the rotating component 3 and the sample placement component 2 are driven back to their initial positions, completing the automatic return operation of the device.
[0035] In one possible implementation, such as Figure 5As shown, it also includes a buffer assembly 6, which includes a separator 61 and a buffer 62. One side of the separator 61 is connected to the side wall of the first support 11, and the other side of the separator 61 is connected to the side wall of the second support 12. The separator 61 is located on one side of the sample placement member 2. One side of the buffer 62 is connected to the side wall of the separator 61, and the other side of the buffer 62 abuts against the sample placement member 2.
[0036] For reference, the separator 61 can be made of a plate with a certain strength and rigidity, such as a metal plate. The separator 61 can be securely connected between the first support 11 and the second support 12 through bolting, welding, or slotting. The buffer 62 can be selected as a buffer such as a rubber pad or rubber column, depending on actual needs.
[0037] In specific application scenarios, when the centrifuge finishes working, the return component 4 moves the sample placement component 2 back to its initial position. During this process, the sample placement component 2 experiences a certain amount of impact. At this time, the buffer component 62 of the buffer assembly 6 acts as a buffer. Taking a rubber column or rubber pad as an example, it can absorb the impact force through its own elastic deformation, thereby reducing the impact force on the sample placement component 2 and the entire device. For example, when storing fragile samples, the buffer component 62 can reduce the possibility of the sample being damaged by the vibration of the device.
[0038] In one possible implementation, such as Figure 5 As shown, the separator 61 divides the first support 11 and the second support 12 into a first placement area 63 and a second placement area 64. A sample placement component 2 is disposed in the first placement area 63, and another sample placement component 2 is disposed in the second placement area 64. The separator 61 is located between the two sample placement components 2, and buffer components 62 are disposed on both sides of the separator 61. Multiple buffer components 62 are provided, spaced apart on the sidewalls of the separator 61.
[0039] For reference, buffer elements 62 are provided on both sides of the separator 61, and multiple buffer elements 62 are provided, which are spaced apart on the side wall of the separator 61. The advantage of this arrangement is that it can more evenly distribute the impact force generated when the sample placement element 2 moves, thereby achieving a better buffering effect.
[0040] The above-described embodiments merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
