[0002] In food and drug testing, it is often necessary to add culture medium to the culture dish for microbial culture experiments. In one experimental sequence, dozens of sample gradient sequences are often required. Manual completion is not only time-consuming and labor-intensive, but also has a high risk of culture medium contamination and the quality of packaging is difficult to guarantee.

[0003] In the prior art, a device that uses an electric drive mechanical structure to achieve culture medium oscillation is proposed. However, the applicant found that the conventional device has the following defects:

[0004] ① If culture medium is spilled on the plate tray, the plate tray is not easy to clean inside the machine;

[0005] ② The sizes of the plates from different manufacturers are different. Even if they are all 9 cm plates, the diameters of the plates from different manufacturers can differ by 1 to 2 mm.

[0041] Figure 1 In the embodiment, the detachable flat tray 200 is in an assembled state. Figure 2 for Figure 1 Schematic diagram of the detachable plate tray in the culture medium plate shaking mechanism in the detached state. Figure 1 and Figure 2 The detachable plate tray 200 is arranged parallel to the horizontal plane, and includes: a fixed structure 210; and a detachable structure 220 engaged with the fixed structure. The fixed structure 210 further includes: an integrally formed connecting portion 211 and an engaging portion; wherein the connecting portion 211 is in a triangular shape, and a first rotating shaft 213 is formed at the top of the triangular shape; and a second rotating shaft 214 and a third rotating shaft 215 are symmetrically formed on the left and right sides of the engaging portion.

[0042] Please continue to refer to Figure 1 The equipment frame 110 includes: a bottom plate 111 , a mounting plate 113 extending from a side plate 112 and parallel to the bottom plate 111 ; and a column 114 supported between the bottom plate 111 and the mounting plate 113 .

[0043] Please continue to refer to Figure 1 The active mechanism 120 includes: a torque output component 121, which is fixed on the bottom plate 111 of the equipment frame and outputs a torque rotating parallel to the horizontal plane; an active eccentric shaft 122, which is in a "Z" shape as a whole, and its driving end is rotatably connected to the torque output component, and the axis of the driving end is parallel to but not coincident with the axis of the torque output component outputting torque, and its free end is rotatably connected to the first rotating shaft of the fixed part of the detachable plate tray. Specifically, the torque output component is a motor, and the active eccentric shaft is a Z-shaped rod.

[0044] Please continue to refer to Figure 1 The two driven mechanisms are arranged symmetrically with respect to the active mechanism. The driven mechanism 130 includes: a bearing seat 131, which is fixed above the mounting plate 113 of the equipment frame, and its rotation plane is parallel to the horizontal plane, and a bearing is fixed inside; a driven eccentric shaft 132, which is in a "Z" shape as a whole, and its driving end is rotatably connected to the other of the inner ring and the outer ring of the bearing, and the axis of the driving end does not coincide with the central axis of the bearing, and its free end is rotatably connected to the second rotating shaft 214 or the third rotating shaft 215 of the fixed part of the detachable plate tray.

[0045] In this embodiment, the torque output component 121 drives the active eccentric shaft 122 to rotate, thereby driving the upper detachable plate tray 200 to perform a smooth arc motion in the horizontal plane, and the driven eccentric shaft 132 rotates accordingly and supports the detachable plate tray.

[0046] The detachable plate tray in this embodiment is further described in detail below. Figure 3A for Figure 2 Schematic diagram of the removable plate tray shown in the horizontal direction. Figure 3B for Figure 3A The detachable plate tray is shown in a three-dimensional cross-sectional view at plane AA. Figure 4A for Figure 2 Schematic diagram of the removable plate tray in longitudinal direction. Figure 4B for Figure 4A The detachable plate tray is shown in cross-section at plane BB.

[0047] Please refer to Figure 1 , Figure 2 , Figure 3A , Figure 3B , Figure 4A , Figure 4B In this embodiment, the detachable plate tray 200 includes: a fixed structure 210 and a detachable structure 220 engaged with the fixed structure. The fixed structure 210 further includes: an integrally formed connecting portion 211 and an engaging portion. The engaging portion includes: a left engaging arm 216 extending forward, a right engaging arm 217, and three intermediate engaging arms 218 therebetween. Four plate holders 221 are formed inside the detachable structure 220, and the left and right sides thereof are respectively detachably engaged with the left engaging arm and the right engaging arm, thereby being combined with the fixed structure as a whole.

[0048] In this embodiment, the fixed structure 210 is made of aluminum alloy; the detachable structure 220 is made of PC plastic. The aluminum alloy is rigid, and the PC plastic has a certain plastic deformation ability. By utilizing the characteristics that a rigid material and a plastic material can be tightly engaged, the detachable part of the plate tray and the fixed part of the plate tray can be tightly attached.

[0049] Those skilled in the art should understand that, in addition to aluminum alloy, other rigid materials can be used to make fixed structures, and in addition to PC plastic, other non-metallic materials with deformation ability can be used to make detachable structures, all of which can implement the present invention and obtain corresponding beneficial effects.

[0050] In this embodiment, in the fixed structure, three holes are respectively opened on the outer sides of the left locking arm and the right locking arm, and spring top ball components 219 are respectively installed in these three holes. The top ball of the spring top ball component is protruding when there is no external pressure, and the top ball sinks inward when there is inward pressure from the outside.

[0051] Figure 5 for Figure 2 The cross-sectional view of the spring top ball in the fixed structure is shown in FIG. Figure 5 As shown, the spring ball 219 comprises: a one-way open shell, a vent hole at the bottom of which is provided; a ball, the rear end of which is pressed against the bottom of the shell by a spring, and the front end of which extends out of the open side of the shell. The vent hole can eliminate air resistance during the compression of the spring.

[0052] In the detachable structure, three top bead positioning holes 222 matching the spring top bead are respectively arranged on the left and right sides, and the size of the top bead positioning holes 222 matches the top bead position on the fixed part of the plate tray.

[0053] In the assembled state, the six top balls corresponding to the spring top ball members 219 on the detachable part are stuck outward in the six top ball positioning holes 222 of the detachable part, thereby playing the role of positioning the detachable part and the fixed part.

[0054] When the detachable part needs to be replaced, the detachable part is pulled outward with force, and the top ball is retracted inward into the spring top ball sleeve after being stressed, so that the detachable part of the plate tray is separated from the fixed part of the plate tray.

[0055] It can be seen that in this embodiment, the plate tray is disassembled into a fixed part and a detachable part. If culture medium is spilled on the plate tray, the detachable part of the plate tray can be easily removed for cleaning. After cleaning, it can be easily snapped into the fixed part of the plate tray, which is convenient for cleaning and disinfecting the contaminated plate tray.

[0056] In some embodiments of the present invention, there are at least two detachable structures, wherein at least one of the parameters of the shape, size, and depth of the plate holders of different detachable structures is different. By setting in this way, different detachable parts can be made for plates of different sizes from various manufacturers, and it is very convenient to replace the detachable plate tray adapted to the plate in the experiment, saving a lot of time for disassembling the entire plate tray and adjusting the shaking platform.

[0057] Those skilled in the art should understand that, in addition to the positioning holes, positioning grooves may be provided on the left and right sides of the detachable structure, respectively, which may also play the role of positioning the detachable part and the fixed part, and may also implement the present invention.

[0058] Those skilled in the art should understand that, in addition to the combination of the spring top bead and the positioning hole, other positioning and fixing methods may be used, such as a convex and concave combination of snaps, etc., which can also implement the present invention, but the convenience is not as good as the present embodiment.

[0059] Please continue to refer to Figure 2 3, in addition to the left and right locking arms, the detachable part also includes: three middle locking arms 218, and a semicircular support structure matching the shape of the plate holder is formed between adjacent locking arms. In the assembled state, the middle locking arms 218 extend between two adjacent plate holders of the detachable structure, which can play a role of guiding and positioning support, making the detachable part more stable and reducing the vibration of the detachable part.

[0060] Those skilled in the art should understand that, although the middle engaging arm is provided in this embodiment, the present invention can also be implemented without the middle engaging arm. In addition, the present invention can also be implemented if only the middle engaging arm is provided without the left engaging arm and the right engaging arm. Moreover, the middle engaging arm only indicates that the engaging arm is not located at the side of the fixed structure, and does not mean that the engaging arm is strictly located at the geometric center of the fixed structure.

[0061] Those skilled in the art should understand that, although four plate holders are provided on the detachable structure in this embodiment, the number of plate holders is not limited in the present invention and can be any number. However, considering the influence of vibration on the plate, the number of plate holders is generally not more than 10.

[0062] Those skilled in the art should understand that, although this embodiment is described using an oscillating mechanism for a culture medium plate as an example, the detachable culture medium plate tray in the present invention can be manufactured and used separately. In addition to the oscillating mechanism for a culture medium plate, the detachable culture medium tray can also be applied to other application scenarios, such as food / pharmaceutical manufacturing, chemical industry, etc.

[0063] Those skilled in the art should understand that, although the present embodiment is described by taking a flat dish as an example, the present invention can also be applied to other vessels, such as beakers, mixing barrels, etc., and it is only necessary to design the vessel holder into a corresponding shape.

[0064] At this point, the various embodiments of the present invention have been introduced. Based on the above description, those skilled in the art should have a clear understanding of the present invention.
