[0025] It can be seen from the above structure that; by setting the frame 1, the base 2, the placement plate 3, the strip groove 4, the partition plate 5, the sealing plate 6, the limiting device, the sliding rod 7, the lifting threaded rod 8 and the lifting device, etc. are used in combination, so that the strip groove 4 and the partition plate 5 divide the internal space of the placement plate 3 into a plurality of small compartments, so as to place different types of chromatography fillers for easy separation, and the sealing plate 6 can be opened by opening the limiting device to facilitate the removal of the required chromatography fillers. Through the cooperation of the lifting device, the sliding rod 7 and the lifting threaded rod 8, the height of the placement plate 3 can be adjusted, so that the height of the internal storage space of the placement plate 3 is adapted to the height of the chromatography filler container, thereby improving the utilization rate of the storage space.

[0026] Furthermore, the lifting device includes a lifting plate 9 slidably mounted on the side wall of the sliding rod 7, and the side wall of the lifting plate 9 is fixedly connected to the side wall of the placement plate 3. The side wall of the lifting plate 9 located on one side of the lifting threaded rod 8 is hinged with an adjusting sleeve 10, and the adjusting sleeve 10 is threadedly connected to the lifting threaded rod 8. By setting the sliding rod 7, the lifting threaded rod 8, the lifting plate 9 and the adjusting sleeve 10 for use together, the adjusting sleeve 10 is rotated to make the adjusting sleeve 10 rise or fall along the lifting threaded rod 8 spirally, thereby driving the lifting plate 9 to slide along the sliding rod 7, and then the storage space between two adjacent placement plates 3 can be adjusted to adapt to the height of the chromatography filler storage container, without leaving too much blank space, thereby improving the utilization of the space.

[0027] Furthermore, the limiting device includes a limiting rod 15 fixedly connected to both sides of the blocking plate 6, and a side wall of the placement plate 3 located on one side of the limiting rod 15 is provided with an inclined limiting groove 14, the side wall of the limiting rod 15 is slidably connected to the inner wall of the inclined limiting groove 14, and the side wall of the placement plate 3 located on one side of the inclined limiting groove 14 is fixedly connected to a spring bin 16, a T-shaped inclined limiting rod 17 is provided inside the spring bin 16, and both ends of the T-shaped inclined limiting rod 17 pass through the side wall of the spring bin 16 and are slidably connected to the spring bin 16 The side wall of the T-shaped inclined plane limiting rod 17 located inside the spring bin 16 is sleeved with a limiting spring 18, and one end of the limiting spring 18 is fixedly connected to the side wall of the T-shaped inclined plane limiting rod 17, and the other end of the limiting spring 18 is fixedly connected to the inner wall of the spring bin 16; by setting the sealing plate 6, the limiting rod 15, the inclined plane limiting groove 14, the spring bin 16, the T-shaped inclined plane limiting rod 17 and the limiting spring 18, when the chromatography filler needs to be taken, the T-shaped inclined plane limiting rod 17 is pulled so that the T-shaped inclined plane limiting rod 17 The limiting spring 18 is squeezed to slide downward, and then leaks out of the inclined limiting slot 14, and then the sealing plate 6 hinged to the placement plate 3 can be pulled to make the limiting rod 15 slide out of the inclined limiting slot 14, leaking out the internal space of the placement plate 3, which is convenient for taking out or putting in the chromatography filler. When the limiting rod 15 slides out of the inclined limiting slot 14, the T-shaped inclined limiting rod 17 is released, and the limiting spring 18 will push the T-shaped inclined limiting rod 17 to automatically block the inclined limiting slot 14, thereby completing the removal or placement of the chromatography filler. After work, the sealing plate 6 is pushed upward, and the limiting rod 15 fixedly connected to the side wall of the sealing plate 6 will slide along the inclined surface of the T-shaped inclined surface limiting rod 17, pushing the T-shaped inclined surface limiting rod 17 to squeeze the limiting spring 18 to automatically descend. When the limiting rod 15 slides out of the inclined surface limiting groove 14, the limiting spring 18 will push the T-shaped inclined surface limiting rod 17 to automatically rise and block the inclined surface limiting groove 14, preventing the limiting rod 15 from sliding out of the inclined surface limiting groove 14, and then preventing the sealing plate 6 from automatically opening, affecting the storage of the chromatographic filler.

[0028] Furthermore, a pressing plate 19 is fixedly connected to the bottom surface of the T-shaped inclined surface limiting rod 17. By setting the pressing plate 19, when opening the sealing plate 6, pressing the pressing plate 19 downward can drive the T-shaped inclined surface limiting rod 17 to descend, thereby facilitating the opening of the sealing plate 6.

[0029] Furthermore, a fixed slide groove 11 is provided on the side wall of the lifting plate 9 located on one side of the slide rod 7, and the inner wall of the fixed slide groove 11 is slidably connected to the arc-shaped fixed plate 12, the arc-shaped end of the arc-shaped fixed plate 12 is against the side wall of the slide rod 7, and a fixed screw 13 is provided on one side of the arc-shaped fixed plate 12, one end of the fixed screw 13 passes through the side wall of the arc-shaped fixed plate 12 and is rotatably connected to the side wall of the lifting plate 9, and the fixed screw 13 is threadedly connected to the arc-shaped fixed plate 12; by setting the fixed slide groove 11, the arc-shaped fixed plate 12 and the fixed screw 13, etc., the arc-shaped fixed plate 12 and the fixed screw 13 can be used to make the lifting plate 9 rotate. When it is necessary to adjust the height of the storage space of the placement plate 3, the fixing screw 13 is rotated to drive the arc-shaped fixing plate 12 threadedly connected to the fixing screw 13 to move outward, so that the arc-shaped end of the arc-shaped fixing plate 12 is separated from the slide bar 7. After that, the height of the storage space of the placement plate 3 can be adjusted by the lifting device. After the adjustment is completed, the fixing screw 13 is rotated in the direction to drive the arc-shaped end of the arc-shaped fixing plate 12 to abut against the side wall of the slide bar 7, thereby fixing the lifting plate 9, and then completing the fixing work of the placement plate 3, thereby enhancing the stability when storing the chromatographic filler.

[0030] Furthermore, the arc-shaped end of the arc-shaped fixing plate 12 is fixedly connected with an anti-skid pad 20; by providing the anti-skid pad 20, when the arc-shaped end of the arc-shaped fixing plate 12 abuts against the side wall of the sliding rod 7, the anti-skid pad 20 will first abut against the side wall of the sliding rod 7, thereby enhancing the friction force at the connection between the arc-shaped end of the arc-shaped fixing plate 12 and the sliding rod 7, and improving the stability of the arc-shaped fixing plate 12 when fixing the lifting plate 9.
