Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may include, for example, a fixed connection, an integral connection, or a detachable connection; may be communication within two elements; the terms may be directly connected or indirectly connected through an intermediate, and those skilled in the art can understand the specific meaning of the terms in the present invention in specific situations.

A preferred embodiment of a centrifugal mechanism is shown in fig. 1 and includes a rotating shaft 10, a mounting plate 11 and a support bar 2. The rotating shaft 10 is externally connected with a power mechanism, and the rotating shaft 10 is driven by the power mechanism to rotate. The technical solution of how the rotating shaft 10 rotates belongs to the prior art, and it is not necessary to describe here more. The mounting plate 10 is fixedly connected to the rotating shaft 10, and when the rotating shaft 10 rotates, the mounting plate 10 rotates together with the rotating shaft 10. As shown in fig. 2, a plurality of mounting grooves 12 are formed on the mounting plate 10, and the mounting grooves 12 are connected to the support rods 2. One end of the support rod 2 is detachably connected in the mounting groove 12, the other end of the support rod is connected with a pore plate placing mechanism 21, and the pore plate placing mechanism 21 is provided with a placing groove 23 for mounting the pore plate 3. Because the supporting rods 2 can be disassembled, the number of the supporting rods 2 can be selected according to actual conditions, and when the number of samples needing centrifugation is large, more pore plates 3 can be arranged on the centrifugal mechanism by adding the supporting rods 2, so that more samples can be subjected to rotary centrifugation simultaneously; when the sample amount is small or the sample is too heavy to cause the rotating shaft 10 to work normally, the load borne by the rotating shaft 10 during rotation is reduced by reducing the number of the supporting rods 2. Therefore, the sample number which can be centrifugally processed at one time can be automatically selected according to the requirement, and the scheme is convenient for practical use.

In a further preferred embodiment, as shown in fig. 1 and 3, the orifice plate placing mechanism 21 is rotatably movably connected to the support rod 2, and the orifice plate placing mechanism 21 can be rotated in a vertical direction. This arrangement has an advantage in that when the rotary shaft 10 is stationary, the state of the well plate placing mechanism 21 is the solid line portion in fig. 1, in which the well plate 3 is horizontal after installation, and thus different portions of each sample placed on the well plate 3 can be naturally sedimented and layered; when the rotation shaft 10 starts to rotate, the well plate placing mechanism 21 automatically turns upward to a state shown by a dotted line under the centrifugal force, so that the sample can be normally centrifugally layered. In order to prevent the well plate 3 or the sample to which the well plate 3 is attached from falling out, as shown in fig. 5, a shutter 211 is provided on a side surface of the well plate placing mechanism 21. The baffle 211 functions to block the orifice plate 3. In order to be able to mount the perforated plate 3 in the placement groove 23, the perforated plate placement mechanism 21 is provided with an opening on the side facing away from the rotary shaft 10 in the corresponding stationary state, and the perforated plate 3 can be placed in the placement groove 23 through the opening; alternatively, the shutter 211 on one side may be configured to be openable and closable, and the aperture plate 3 may be inserted after the shutter 211 on one side is opened. Since the solution is too numerous, it is not exemplified here, and the skilled person will understand how to put the well plate 3.

As shown in fig. 6, a plurality of auxiliary mounting holes 24 are provided on the bottom surface of the placement groove 23, and the auxiliary mounting holes 24 correspond to the mounting holes of the orifice plate 3 one by one. Supplementary mounting hole 24 both can carry out supplementary fixed to the sample, still can provide spacingly for orifice plate 3 simultaneously, this is because the sample can be packed into supplementary mounting hole 24 and mounting hole simultaneously to orifice plate 3 can be fixed, prevents that orifice plate 3 from rocking in centrifugal process.

As shown in fig. 3, the specific connection manner of the orifice plate placement mechanism 21 and the support rod 2 is that a connection portion 22 is disposed on the support rod 2, the connection portion 22 is rotatably and movably connected with a connection shaft 220, and the orifice plate placement mechanism 21 is fixedly connected with the connection shaft 220.

In order to fix the support rod 2 conveniently, as shown in fig. 4, a support rod fixing portion 20 capable of swinging is disposed on the support rod 2, meanwhile, a fixing block 201 is disposed on a surface of the support rod fixing portion 20, a clamping groove 120 is disposed on a surface of the mounting plate 11, and the clamping groove 120 is adapted to the fixing block 201. After the supporting rod 2 is installed in the installation groove 12, the supporting rod fixing portion 20 is inserted into the installation groove 12, and meanwhile, the fixing clamping block 201 is clamped into the clamping groove 120. Draw-in groove 120 sets up on mounting panel 11 surface, when the bracing piece 2 was taken off to needs, presses fixed fixture block 201, and bracing piece fixed part 20 swings a short distance for inside fixed fixture block 201 retraction mounting groove 12, just can directly extract bracing piece 2 this moment. The scheme can conveniently and fixedly connect the support rod 2 with the mounting groove 12 in a detachable way.

In this embodiment, the number of the mounting grooves 12 is six, and the mounting grooves 12 are uniformly arranged along the circumferential direction of the mounting plate 11. Through tests, the maximum number of the support rods 2 which can be driven by the power mechanism of the centrifuge commonly used in the laboratory is about six, so that the centrifuge is provided with six mounting grooves 12. The design purpose of the uniformly arranged mounting grooves 12 is to install the support rods 2 symmetrically when the support rods 2 are installed, so as to prevent the service life of the rotating shaft 10 from being affected by uneven stress.

In summary, the above description is only a preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention should be included within the scope of the present invention.
