Description

Technical Field

[0001] The utility model relates to the technical field of biomedical experimental equipment, in particular to a microplate placement rack. Background Art

[0002] In the prior art, experimental operations involving biological samples usually need to be carried out in a biological safety cabinet. However, due to the limited space inside the biological safety cabinet, the operating space for experimental personnel is extremely limited. Especially when conducting biomedical experiments such as drug screening and cell culture, a large number of microplates are required. During the experiment, the microplates to be used are placed side by side in the safety cabinet for easy operation of each microplate. This method not only occupies a large amount of the internal space of the safety cabinet but also makes it inconvenient to operate the microplates located inside the safety cabinet. In addition, during the experiment, it is also necessary to place the microplates to be used. If the microplates to be used are placed outside the safety cabinet, it is not convenient to take and place the microplates. If the microplates to be used are placed inside the safety cabinet on one side of the microplates in use, it will further occupy the internal space of the safety cabinet, resulting in a reduction in the space for the microplates to be used, and thus it is impossible to operate a large number of microplates.

[0034] Refer to Figure 1 and Figure 2, an embodiment of the present utility model provides a microplate placement rack, which includes a base 100, two sets of rotating components, and a carrier plate 300. The base 100 is provided with mounting posts 110 arranged in the up-down direction. The rotating component includes a rotating member 200 and four connecting rods 210. The rotating member 200 is rotatably mounted on the mounting post 110 and can rotate circumferentially around the mounting post 110. The connecting rods 210 are connected to the rotating member 200 and extend outward from top to bottom. All the connecting rods 210 are arranged at intervals along the circumferential direction of the rotating member 200. The rotating members 200 of the two sets of rotating components are arranged in sequence in the up-down direction. Among them, a carrier plate 300 for placing a microplate is connected to the lower end of each connecting rod 210. The carrier plate 300 is located above the base 100. The upper surface of the base 100 also has two placement positions 120 for placing microplates. In the up-down direction, the projection of the placement position 120 is located between the projection of the mounting post 110 and the projections of the respective microplates.

[0035] By adopting the microplate placement rack of the embodiment of the present utility model, when conducting an experiment, the microplate placement rack is placed in a safety cabinet. Two rotating members 200 are rotatably mounted on the mounting post 110. Each rotating member 200 is connected to four carrier plates 300 through four connecting rods 210. Therefore, the microplates that need to be used can be placed on the carrier plates 300 for operation, that is, eight microplates that need to be used can be placed simultaneously, which not only effectively utilizes the planar space of the safety cabinet but also effectively utilizes the longitudinal space inside the safety cabinet, greatly improving the space utilization rate of the safety cabinet. Secondly, during the experiment, the required carrier plate 300 can also be rotated to a position close to the experimenter through the rotating member 200, thus avoiding the problem that the microplates located inside the safety cabinet are not convenient to take and place. This not only facilitates the taking and placing of each microplate but also makes the operation of the experimenter more convenient. In addition, by arranging the connecting rods 210 to extend outward from top to bottom and setting the placement positions 120 for placing microplates on the upper surface of the base 100, in the up-down direction, the projection of the placement position 120 is located between the projection of the mounting post 110 and the projections of the respective microplates. Thus, the microplates to be used can be stacked and placed on the placement positions 120 on the upper surface of the base 100, which not only effectively utilizes the space between the mounting post 110 and the respective carrier plates 300 but also enables the experimenter to conveniently take the microplates from the placement positions 120 to the carrier plates 300 for operation, or place the microplates back from the carrier plates 300 to the placement positions 120, making the taking and placing of the microplates more convenient and conducive to improving the operation efficiency of the experimenter.

[0036] It can be understood that the number of the above-mentioned rotating components is two groups, which is only for Figure 1 and Figure 2An exemplary description does not represent a specific limitation on the present utility model. The number of rotation assemblies can be not only two groups, but also three groups, four groups or more groups. The present utility model does not make specific limitations on this and can be flexibly selected according to the actual use environment.

[0037] It can be understood that each group of the above rotation assemblies includes four connecting rods 210, which is only an exemplary description of Figure 1 and Figure 2 and does not represent a specific limitation on the embodiments of the present utility model. In each group of rotation assemblies, the number of connecting rods 210 connected to the rotating member 200 can be not only four, but also two, three, five, six or more. The present utility model does not make specific limitations on this and can be flexibly selected according to the actual use environment.

[0038] It can be understood that referring to Figure 1 and Figure 2 , the two placement positions 120 are correspondingly arranged on the opposite sides of the mounting column 110. Thus, not only can the space above the base 100 be reasonably arranged, so that more microplates to be used can be placed on the upper surface of the base 100, but also it is convenient for the experimenter to take the microplates. It can be understood that the two placement positions 120 can be not only correspondingly arranged on the opposite sides of the mounting column 110, but also located at other positions on the upper surface of the base 100. The present utility model does not make specific limitations on this. In addition, it can be understood that the number of the above placement positions 120 is two, which is only an exemplary description of Figure 1 and Figure 2 and the number of placement positions 120 can be not only two, but also one, three, four or more. The present utility model does not make specific limitations on this.

[0039] Referring to Figures 1 to 5 , in some embodiments, the carrier plate 300 includes a bottom plate 310 and a surrounding plate 320 wound around the outer periphery of the bottom plate 310. The bottom plate 310 and the surrounding plate 320 enclose each other to form a placement cavity 330 for accommodating the microplate, and the surrounding plate 320 is installed on the corresponding connecting rod 210.

[0040] By adopting the above structure, when in use, the microplate can be placed in the placement cavity 330 of the carrier plate 300. The bottom plate 310 can support the microplate, and the surrounding plate 320 can limit the microplate, preventing the microplate from falling from the carrier plate 300 during the experiment and preventing the microplate from swinging greatly, resulting in the liquid in the microplate splashing out of the carrier plate 300. Therefore, it is beneficial to the experiment and to maintaining the experimental environment in the safety cabinet.

[0041] It can be understood that the above surrounding plate 320 is installed on the corresponding connecting rod 210, which is only forFigures 1 to 5 As an exemplary illustration, in order to install the loading tray 300 on the corresponding connecting rod 210, in addition to installing the enclosure 320 on the corresponding connecting rod 210, the bottom plate 310 can also be installed on the corresponding connecting rod 210, or the enclosure 320 and the bottom plate 310 can be installed on the corresponding connecting rod 210 at the same time, and the present invention does not make specific limitations on this.

[0042] It is understandable that the loading tray 300 and the connecting rod 210 can be installed and connected specifically by bolt fasteners. In addition, the loading tray 300 and the connecting rod 210 can also be installed by welding, clamping or other connection methods, which is not specifically limited in the present invention.

[0043] Reference Figures 1 to 5 In some embodiments, the enclosure 320 is provided with a first clearance groove 340 which is connected to the storage cavity 330 , and the first clearance groove 340 runs through the upper edge of the enclosure 320 .

[0044] By adopting the above structure, the first give way groove 340 is opened in the enclosure 320 and extends to the upper edge of the enclosure 320, so that the experimenter can put the microplate into the storage cavity 330 of the loading tray 300 or take the microplate out of the storage cavity 330 of the loading tray 300 through the first give way groove 340, that is, the opening of the first give way groove 340 provides an operating space for taking and placing the microplate in the loading tray 300, making it more convenient to take and place the microplate.

[0045] It is understandable that, in order to facilitate the operation of the experimenter, the number of the first yielding grooves 340 can be one, two, three or more, and the present invention does not make any specific limitation on this.

[0046] Reference Figures 1 to 5 In some embodiments, the first clearance groove 340 is located on a side of the enclosure 320 that is away from the corresponding connecting rod 210 .

[0047] In the above structure, by arranging the first clearance groove 340 on the side of the enclosure 320 away from the corresponding connecting rod 210, when the loading plate 300 is rotated to the side close to the experimenter, the first clearance groove 340 faces the experimenter, thereby enabling the experimenter to take and place the microplate more conveniently.

[0048] It is understandable that the first clearance groove 340 is arranged on the side of the enclosure 320 away from the corresponding connecting rod 210, which is only for Figures 1 to 5An exemplary illustration is that, in addition to setting the first relief groove 340 on the side of the surrounding plate 320 facing away from the corresponding connecting rod 210, the first relief groove 340 can also be set on the side of the surrounding plate 320 connected to the connecting rod 210, or the first relief groove 340 can also be set at other positions of the surrounding plate 320. The present utility model does not make specific limitations on this.

[0049] It can be understood that in some embodiments, when the number of the first relief grooves 340 is two, the two first relief grooves 340 can be correspondingly set on the opposite sides of the surrounding plate 320. Specifically, one first relief groove 340 can be set on the side of the surrounding plate 320 facing away from the corresponding connecting rod 210, and the first relief groove 340 can also be set on the side of the surrounding plate 320 connected to the connecting rod 210. The present utility model does not make specific limitations on the specific distribution positions of the emerald first relief grooves 340.

[0050] Refer to Figures 1 to 5 , in some embodiments, the first relief groove 340 extends downward from the upper edge of the surrounding plate 320 to penetrate through the bottom plate 310. The bottom plate 310 is provided with a second relief groove 350. The second relief groove 350 is located on one side of the first relief groove 340 and is communicated with the first relief groove 340. The second relief groove penetrates through the bottom plate 310 in the up and down direction.

[0051] In the above structure, by making the first relief groove 340 penetrate through the bottom plate 310 downward and opening the second relief groove 350 communicated with the first relief groove 340 on the bottom plate 310, the experimenter can clamp the microplate from the upper and lower sides of the microplate, and stably place the microplate in the placement cavity 330 of the carrier plate 300 or take out the microplate from the placement cavity 330 of the carrier plate 300 through the first relief groove 340 and the second relief groove 350. Furthermore, not only the placement and removal of the microplate are made more stable, but also the convenience of placing and removing the microplate is further improved.

[0052] Refer to Figures 1 to 5 , in some embodiments, the surrounding plate 320 includes a first surrounding plate 321 and a second surrounding plate 322. The first surrounding plate 321 is connected to the bottom plate 310 and is arranged along the circumference of the bottom plate 310. The second surrounding plate 322 is connected to the upper end of the first surrounding plate 321 and extends outward from bottom to top.

[0053] By adopting the above structure, the first surrounding plate 321 can limit the microplate in the placement cavity 330, and the second surrounding plate 322 can guide the placement and removal of the microplate, making the placement and removal of the microplate more convenient and fast.

[0054] It can be understood that the first enclosing plate 321, the second enclosing plate 322 and the bottom plate 310 can specifically adopt an integrally formed structure, thereby making the structure of the carrier tray 300 simpler and facilitating the production and processing of the carrier tray 300. Of course, in addition, the first enclosing plate 321, the second enclosing plate 322 and the bottom plate 310 can also adopt welding, clamping, plugging or other connection methods, and the present utility model does not make specific limitations thereto.

[0055] Referring Figure 1 , Figure 2 and Figure 8 , in some embodiments, in each set of rotating components, the connecting rod 210 is rotatably connected to the rotating member 200, and a locking member (not shown in the figure) is further provided between the connecting rod 210 and the rotating member 200. The locking member can lock or unlock the rotating member 200 and the connecting rod 210. When the locking member is unlocked, the connecting rod 210 can rotate upward or downward relative to the rotating member 200.

[0056] By adopting the above structure, when the locking member unlocks the rotating member 200 and the connecting rod 210, the connecting rod 210 can rotate upward or downward relative to the rotating member 200, so that the horizontal height of the corresponding carrier tray 300 can be adjusted. When the locking member locks the connecting rod 210, the carrier tray 300 can be maintained at the adjusted horizontal height. Thus, during the experiment, the experimenter can rotate the connecting rod 210 upward or downward relative to the rotating member 200 as needed, so that the carrier tray 300 can be adjusted to a suitable height, which makes the operation of the experimenter more convenient. In addition, when the connecting rod 210 rotates upward, the carrier tray 300 can move away from the mounting post 110, and when the connecting rod 210 rotates downward, the carrier tray 300 can move toward the mounting post 110. Thus, the experimenter can also adjust the horizontal distance between the carrier tray 300 and himself as needed, which further makes the operation of the experimenter more convenient and further improves the use flexibility of the microplate placement rack.

[0057] It can be understood that the connecting rod 210 is rotatably connected to the rotating member 200, and a locking member is further provided between the connecting rod 210 and the rotating member 200. Specifically, the locking member can be a damping member provided between the connecting rod 210 and the rotating member 200. When there is a tendency of relative rotation between the connecting rod 210 and the locking member, a frictional force will be generated between the damping member and the connecting rod 210 and / or between the damping member and the rotating member 200 to prevent the relative rotation of the connecting rod 210 and the locking member. When the external force applied is greater than the frictional force generated by the damping member, the damping member can unlock the rotating member 200 and the connecting rod 210, that is, the connecting rod 210 can rotate upward or downward relative to the rotating member 200. When the external force applied is less than the frictional force generated by the damping member, the damping member can lock the rotating member 200 and the connecting rod 210, so that the relative static state is maintained between the connecting rod 210 and the rotating member 200, thereby being able to maintain the loading tray 300 at the adjusted horizontal height.

[0058] It can be understood that in addition to being set as a damping member, in some embodiments, the locking member can also be an abutting column movably installed on the rotating member 200 and capable of abutting against the outer peripheral wall of the connecting rod 210. When the abutting column is separated from the connecting rod 210, the connecting rod 210 is in an unlocked state, and at this time, the connecting rod 210 can rotate upward or downward relative to the rotating member 200. When the abutting column abuts against the outer peripheral wall of the connecting rod 210, the connecting rod 210 is in a locked state, and at this time, the relative static state is maintained between the connecting rod 210 and the rotating member 200. Alternatively, a plurality of locking holes can also be opened on the connecting rod 210, and the abutting column is movably installed on the rotating member 200 and can be inserted into different locking holes, so as to lock the connecting rod 210 at different angles, and further fix the loading tray 300 at different heights. It can be understood that in addition to movably installing the abutting column on the rotating member 200, in some embodiments, the rotating member 200 is provided with a rotating shaft rotatably connected to the abutting column, the abutting column is movably installed on the connecting rod 210 and can abut against the rotating shaft. In addition, a plurality of locking holes can also be opened on the rotating shaft, and the abutting column can be inserted into different locking holes to lock the connecting rod 210 at different angles, and further fix the loading tray 300 at different heights. Of course, in addition to the above-mentioned damping member or abutting column, other locking structures can also be adopted for the locking member between the connecting rod 210 and the rotating member 200, and the present invention does not make specific limitations thereon.

[0059] It can be understood that, in order to maintain the horizontal arrangement of the loading tray 300 for facilitating the horizontal placement of the microplate, a locking structure can also be provided between the loading tray 300 and the connecting rod 210. This locking structure can adopt the same structure as the locking member between the connecting rod 210 and the rotating member 200, and the present utility model does not make specific limitations thereto. Of course, in some embodiments, during the use of the microplate placement rack, the rotation angle of the connecting rod 210 is not too large, that is, the rotation angle of the loading tray 300 following the connecting rod 210 is not too large. Therefore, it is not easy to cause the samples inside the microplate in the loading tray 300 to spill due to inclination. Therefore, for the convenience of the installation and assembly between the loading tray 300 and the connecting rod 210, the loading tray 300 and the connecting rod 210 can also be fixedly connected. Specifically, the loading tray 300 and the connecting rod 210 can be fixedly connected through connection structures such as screw fasteners and clamping structures, and the present utility model does not make specific limitations thereto.

[0060] Referring to Figure 1 , Figure 2 and Figures 6 to 8 , in some embodiments, a limiting structure corresponding to each rotating member 200 is provided on the outer peripheral wall of the mounting post 110, and the limiting structure can abut against the upper surface and the lower surface of the rotating member 200.

[0061] In the above structure, by providing the limiting structure to limit the rotating member 200 from the upper and lower sides of the rotating member 200, it is possible to avoid the situation of the rotating member 200 jittering up and down or slipping down during use, which is beneficial to improving the rotation stability of the rotating member 200.

[0062] Referring to Figure 1 , Figure 2 and Figures 6 to 8 , in some embodiments, the limiting structure is an annular limiting groove 111 opened on the outer peripheral wall of the mounting post 110, the rotating member 200 is sleeved on the inner peripheral wall of the limiting groove 111, the upper side wall of the limiting groove 111 abuts against the upper surface of the rotating member 200, and the lower side wall of the limiting groove 111 abuts against the lower surface of the rotating member 200.

[0063] By adopting the above structure, the limiting structure is set as the annular limiting groove 111 opened on the outer peripheral wall of the mounting post 110, which has a simple structure and is convenient for processing, and can effectively limit the rotating member 200.

[0064] It can be understood that in addition to being set as the annular limiting groove 111 formed on the outer peripheral wall of the mounting post 110, in some embodiments, the rotating member 200 can also be sleeved on the mounting post 110, and an upward abutting portion and a downward abutting portion protruding outward are arranged on the outer periphery of the mounting post 110. The upward abutting portion is abutted against the upper surface of the rotating member 200, and the downward abutting portion is abutted against the lower surface of the rotating member 200. Of course, in addition to this, other limiting structures can also be adopted to limit the rotating member 200, and the present utility model does not make specific limitations thereto.

[0065] Referring to Figure 1 , Figure 2 and Figures 6 to 7 , in some embodiments, the placement position 120 is a placement groove formed on the upper surface of the base 100.

[0066] By adopting the above structure, the placement position 120 is set as a placement groove structure. During the experiment, the microplates to be used can be stacked and placed in the placement position 120, and the lowermost microplate is placed in the placement groove. Thereby, the microplates to be used can be limited, and it is avoided that the microplates to be used are displaced and interfere with the external carrier plate 300. Furthermore, the influence of the microplates to be used on the operation of the experimenter and the progress of the experiment can be reduced, which is beneficial to the smooth progress of the experiment.

[0067] The embodiments of the present utility model have been described in detail above with reference to the drawings. However, the present utility model is not limited to the above embodiments.
