Description

Technical Field

[0001] This utility model relates to the field of electrophoretic glass plate drying technology, specifically a polyacrylamide gel electrophoresis glass plate drying device. Background Technology

[0002] Polyacrylamide gel electrophoresis is a commonly used electrophoresis technique that uses polyacrylamide gel as the supporting medium to separate proteins and oligonucleotides. Polyacrylamide gel is polymerized from monomers acrylamide and methylenebisacrylamide. The polymerization process is completed by free radical catalysis. There are two forms of polyacrylamide gel electrophoresis: non-denaturing polyacrylamide gel electrophoresis and SDS-polyacrylamide gel electrophoresis. Glass plates are required in the polyacrylamide gel electrophoresis process, and the glass plates need to be cleaned and dried after the experiment.

[0003] According to the patent application "A drying device for polyacrylamide gel electrophoresis glass plates (publication number: CN211012279 U; application number: 201921845520.7)", the above application addresses the following issues: "existing polyacrylamide gel electrophoresis glass plate drying devices do not have a glass plate wiping function, making it inconvenient to clean water droplets on the glass plate surface. Secondly, existing polyacrylamide gel electrophoresis glass plate drying devices cannot achieve glass plate rotation during drying, resulting in uneven heating of the glass plate and slow drying." However, the drying device in the above application cannot position the glass plate inside the drying equipment during use. The glass plate is easily blown by airflow during the drying process, causing positional displacement. The stacking of multiple glass plates affects the drying effect. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] This utility model provides a technical solution:

[0026] Example 1

[0027] Combination Figures 1 to 4 A drying device for polyacrylamide gel electrophoresis glass plates includes a drying equipment box 3, a support leg 31 fixedly connected to the bottom of the drying equipment box 3, a closing door 4 hinged to the front side of the drying equipment box 3, a placement mechanism 1 provided inside the drying equipment box 3, a glass slide 5 provided inside the placement mechanism 1, and positioning mechanisms 2 provided on the left and right sides of the drying equipment box 3.

[0028] The placement mechanism 1 includes a placement component 11 and a clamping component 12. The placement component 11 is disposed inside the drying equipment housing 3, and the clamping component 12 is disposed inside the placement component 11.

[0029] The placement component 11 includes a slide 1101, which is fixedly connected to the left and right sides inside the drying equipment housing 3. A placement rack 1102 is engaged inside the slide 1101. A handle 1103 is fixedly connected to the front of the placement rack 1102. A mesh plate 1104 is provided below the placement rack 1102 and is fixedly connected to the drying equipment housing 3. The clamping component 12 includes a positioning clamp 1201, which is slidably connected to the top of the placement rack 1102. Movable slide rods 1202 are fixedly connected to the left and right sides of the strip 1201. The movable slide rods 1202 are slidably connected to the left and right sides of the placement rack 1102. A slide cylinder 1203 is fixedly connected to the outside of the movable slide rods 1202. The slide cylinder 1203 is slidably connected to the left and right sides of the placement rack 1102. A compression spring 1204 is fixedly connected to the rear side of the slide cylinder 1203. The glass slide 5 is set in the top of the placement rack 1102. The front side of the glass slide 5 is in contact with the rear side of the positioning clip strip 1201.

[0030] Furthermore, the operator only needs to pull the handle 1103 to insert the placement rack 1102 into the slide groove 1101 to complete the assembly and disassembly of the placement rack 1102. The operation is simple and convenient for the operator. At the same time, after the glass slide 5 is placed in the top of the placement rack 1102, the slide cylinder 1203 will move backward by moving the positioning clamp 1201 through the moving slide rod 1202 under the action of the compression spring 1204. This makes the rear side of the positioning clamp 1201 fit with the front side of the glass slide 5 to complete the positioning of the glass slide 5. This ensures that the position of the glass slide 5 placed in the top of the placement rack 1102 will not shift when the drying equipment box 3 is working, and that the multiple glass slides 5 will not stack on each other, thus increasing the drying effect of the glass slides 5 when the device is in use.

[0031] Example 2

[0032] See Figure 1 , Figure 2 and Figure 5 Furthermore, based on Embodiment 1, the positioning mechanism 2 includes a positioning component 21 and an external pull component 22. The positioning component 21 is disposed on the left and right sides of the drying equipment box 3, and the external pull component 22 is disposed on the outside of the positioning component 21.

[0033] The positioning component 21 includes a fixed box 2101, which is fixedly connected to the left and right sides of the drying equipment box 3. A second slide cylinder 2102 is slidably connected inside the fixed box 2101. A return spring 2103 is fixedly connected to the inner side of the second slide cylinder 2102. The return spring 2103 is fixedly connected to the inner and outer sides of the fixed box 2101. A clamping plate 2104 is fixedly connected to the inner side of the second slide cylinder 2102. The clamping plate 2104 is clamped to the left and right sides of the drying equipment box 3 and the slide groove 1101. The rear side of the clamping plate 2104 is in contact with the front side of the placement rack 1102. The external pull component 22 includes a telescopic slide rod 2201, which is fixedly connected to the outer side of the second slide cylinder 2102. The telescopic slide rod 2201 is slidably connected to the inner side of the fixed box 2101. A pull rod 2202 is fixedly connected to the outer side of the telescopic slide rod 2201.

[0034] Furthermore: After the placement rack 1102 is installed, the slide cylinder 2102 will move the clamping plate 2104 inward under the action of the return spring 2103, thus completing the positioning of the placement rack 1102 and increasing the stability of the placement rack 1102 after installation. At the same time, the staff only needs to pull the pull rods 2202 on the left and right sides outward to drive the clamping plate 2104 back into the fixed box 2101 to release the positioning of the placement rack 1102, which is convenient for the staff to disassemble the placement rack 1102. The operation is simple and convenient for the staff to use.

[0035] In actual operation, when this device is used and the glass slide 5 needs to be dried, the operator first moves the positioning clip 1201 forward, then places the glass slide 5 inside the top of the placement rack 1102, so that the rear side of the glass slide 5 is in contact with the rear side of the top of the placement rack 1102. Then the operator releases the pull on the positioning clip 1201. At this time, the slide cylinder 1203, under the action of the compression spring 1204, moves the positioning clip 1201 backward through the moving slide rod 1202. The positioning clip 1201 moves forward and is in contact with the front side of the glass slide 5. At this time, the installation of the glass slide 5 is completed.

[0036] Then, the staff pulls the left and right levers 2202 outwards. The outward movement of the levers 2202 causes the card plate 2104 to retract into the fixed box 2101 via the telescopic slide rod 2201 and the second slide cylinder 2102. After that, the staff holds the handle 1103 and inserts the placement rack 1102 into the slide groove 1101, so that the rear side of the placement rack 1102 is in contact with the rear side of the slide groove 1101. At this time, the limitation on the left and right levers 2202 is released. At this time, the second slide cylinder 2102 drives the card plate 2104 inwards under the action of the return spring 2103. The card plate 2104 moves inwards through the drying equipment box 3 and the slide groove 1101 to the front side of the placement rack 1102. At this time, the positioning of the placement rack 1102 is completed. After that, the staff only needs to close the closing door 4 to start the drying equipment box 3 to dry the glass slides 5 inside.
