DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] A culture dish batch transfer frame, as shown in Figures 1-4 The upper clamp plate 5 and the lower clamp plate 1 are similar in structure, a plurality of groups of length-adjustable slide rod assemblies are arranged between the upper clamp plate 5 and the lower clamp plate 1, the distance between the upper clamp plate 5 and the lower clamp plate 1 can be adjusted, so that the upper clamp plate 5 and the lower clamp plate 1 can clamp different numbers of stacked culture dishes, the upper clamp plate 5 is provided with a micro-pressure assembly, when a plurality of groups of stacked culture dishes are placed between the upper clamp plate 5 and the lower clamp plate 1, there is a gap between the upper clamp plate 5 and the uppermost culture dish, the lower end of the micro-pressure assembly is located below the upper clamp plate 5, the micro-pressure assembly is used, and the lower end of the micro-pressure assembly is lowered to exert a small pressure on the upper end of the culture dish.

[0026] The slide rod assembly comprises a lower rod 7 and an upper rod 8, which are respectively installed on the lower clamp plate 1 and the upper clamp plate 5, and the number of each is a plurality of groups, the upper clamp plate 5 and the lower clamp plate 1 are supported, the upper rod 8 is slidably installed with the lower rod 7, the distance between the upper clamp plate 5 and the lower clamp plate 1 is adjusted, and the upper clamp plate 5 and the lower clamp plate 1 are suitable for clamping different numbers of culture dishes.

[0027] When the length of the upper rod 8 and the lower rod 7 is adjusted, the part of the slide rod assembly without the clamping block 12 (two sets of slide rod assemblies) can be directly pulled to adjust the length, and the part of the slide rod assembly with the clamping block 12 (two sets of slide rod assemblies) is provided with a damping layer between the slide groove 10 and the clamping block 12, so that the clamping block 12 is slowly reset after being retracted, and the upper rod 8 and the lower rod 7 are easily adjusted. When the length of the slide rod assembly is adjusted, the clamping block 12 is pressed to be retracted into the upper rod 8, and the upper rod 8 and the lower rod 7 slide relative to each other. After the length is adjusted, the clamping block 12 is opposite to the adjusting hole 9, the spring 11 presses the clamping block 12, the end of the clamping block 12 penetrates through the adjusting hole 9, and the length of the upper rod 8 and the lower rod 7 is fixed. The node distance of the adjusting hole 9 is 15 mm, 100 mm, 120 mm or 150 mm, which is the general height of a culture dish.

[0028] After the culture dishes are arranged between the upper clamping plate 5 and the lower clamping plate 1, the knob 14 is rotated to drive the screw rod 15 to rotate, and the rotator 16 at the lower end of the screw rod 15 is lowered to press the upper culture dishes and increase the stability of the stacked culture dishes.

[0029] When the rotator 16 rotates, the indicating line 17 corresponds to different values of the scale line 18, and the rotation angle of the rotator 16 can be observed.

[0030] The placing grooves 4 are both thick at the middle and thin at the edges, which limit the culture dishes and prevent the culture dishes from being separated from the lower clamping plate 1 or the upper clamping plate 5. The rubber ring 3 increases the friction between the culture dishes and the lower clamping plate 1 to prevent the culture dishes from falling off.

[0031] The slope 2 facilitates the pushing in and out of the culture dishes, and the handle 6 facilitates the movement and transfer of the frame.

[0032] In this example, the clamping block 12 is manually controlled.

[0033] The clamping block 12 can also be controlled by the handle 6, as disclosed in the application number “201920434066.X”, that is, the button provided on the pull rod handle can control the extension and retraction of the pull rod, which is prior art and will not be described here.

[0034] The working principle of the culture dish batch transfer frame provided by the utility model is as follows:

[0035] Put the transfer frame on the workbench, press the clamping block 12, pull up the upper clamping plate 5, adjust the height between the upper clamping plate 5 and the lower clamping plate 1 according to the approximate height of the stack of culture dishes to be transferred, after adjustment, the clamping block 12 is popped into the new adjustment hole 9 under the action of the spring 11, push the stack of culture dishes along the slope 2 of the lower clamping plate 1, make the bottom sit on the rubber ring 3 of the placing groove 4 of the lower clamping plate 1, rotate the knob 14 of the micro-pressure assembly, drive the rotator 16 to extrude the topmost culture dish downward, the rotator 16 applies a small but sufficient pressure to the culture dish, so that the culture dish is firmly clamped between the upper clamping plate 5 and the lower clamping plate 1, avoiding shaking or falling of the culture dish during the transfer process.

[0036] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
