Description

Technical Field

[0001] The utility model relates to the field of biotechnology, in particular to an electrophoresis clamp. Background Art

[0002] Electrophoresis is a commonly used biological separation technology. It uses electric fields to move charged particles in gel or liquid media and separates them according to their size, shape and charge. Electrophoresis is widely used in molecular biology, protein chemistry, genetic engineering and other fields. Electrophoresis fixtures are auxiliary tools in electrophoresis experiments. They are used to fix and support electrophoresis samples to help separate and analyze samples.

[0003] Existing electrophoresis clamps are usually designed to be suitable for samples of specific thickness, which means that these electrophoresis clamps may only be able to clamp samples of a single thickness; some electrophoresis clamps may also have adjustable clamping parts so that they can adapt to gels or samples of different thicknesses, but such electrophoresis clamps with adjustable clamping thickness are mostly used independently, and have limitations when clamping multiple sample plates, making it inconvenient to clamp samples of various sizes and types in the same set of electrophoresis clamps.

[0008] Furthermore, the mounting base is in a "concave" shape, a mounting groove is provided on the bottom wall of the mounting base, and a cover plate for sealing the mounting groove is fixedly connected to the lower end of the mounting base.

[0012] Furthermore, a movable hole is formed at one end of the adjustment seat away from the connecting rod, and the number of the adjustment seats is the same as the number of the clamping plates.

[0013] By adopting the above technical solution and setting the movable hole, the handle can drive the adjusting column to move its position.

[0014] Furthermore, a handle is fixedly connected to the outer side of the adjusting column, and the handle is located on the inner side of the movable hole. One end of the adjusting column passes through and extends to the outer side of the adjusting seat.

[0019] By adopting the above technical solution, the arrangement of the fixed component is made so that the installation between the mounting base and the electrophoresis box is more stable, thereby preventing the mounting base from tipping over in the electrophoresis box.

[0020] Furthermore, the number of the threaded sleeves is two and they are symmetrically distributed; the threaded sleeves are movably connected to the mounting base via bearings; and the outer sides of the threaded sleeves are fixedly connected to anti-slip pads.

When it is necessary to clamp a second sample of different thickness, the adjustment seat is also adjusted and locked. Therefore, when performing electrophoretic separation of samples of different thicknesses, the samples of different thicknesses can be performed synchronously, which improves the efficiency of electrophoretic separation and enhances the practicality of the electrophoresis clamp; 2. By setting up a fixing component, when the threaded sleeve rotates, the threaded rod can drive the fixing plate to fit closely with the inner wall of the electrophoresis box, thereby improving the stability between the mounting base and the electrophoresis box.
