A trolley structure for electrophoresis apparatus
This utility model relates to the field of electrophoresis hanger technology and discloses a trolley structure for electrophoresis hangers, including a base frame. The base frame has rectangular casters distributed at its bottom, and symmetrical support frames are provided at its top. A first crossbar is installed between the two support frames, located on the side of the support frame away from the base frame. A guide rail is provided at the top of the first crossbar, and an electrophoresis hanger body is movably connected to the guide rail below the first crossbar. This utility model, through the braked casters at the bottom of the base frame and the handrails on the outside of the support frames, allows the trolley to be easily pushed to achieve multi-station transfer of hangers, replacing manual handling. With the cooperation of the guide rail and hooks, multiple sets of electrophoresis hanger bodies can be centrally and orderly suspended, with a single transfer capacity far exceeding that of manual labor, improving production cycle time and preventing hanger collisions and deformation. Combined with the ground support of the hanger's own support rod, the double structure prevents workpieces from falling off and scratching, reducing losses.
