The utility model discloses an automatic focusing motor assembling device which comprises a base, dampers, a working table, an assembling structure and a containing structure, the dampers are arranged at the four corners of the upper portion of the base, the working table is fixedly arranged above the dampers, the assembling structure is fixedly arranged on the base, and the containing structure is fixedly arranged on the base. The utility model belongs to the technical field of assembly equipment, particularly relates to automatic focusing motor assembly equipment, and effectively solves the problems that the assembly of an automatic focusing motor generally relates to the combination of a coil, a magnet, a lens cone and other parts, the traditional process depends on manual positioning and assembly, and the technical capabilities of personnel are different, so that the assembly error is large, and the assembly cost is high. Products are uneven in quality, low in efficiency and easy to pollute.

This utility model relates to the field of hydraulic pump technology, specifically disclosing a hydraulic pump with a leakage alarm function. It includes a base plate with four fixing components on its top. A hydraulic pump body is fixedly mounted on top of these four fixing components. An oil inlet and an oil outlet are respectively located on both sides of one side of the hydraulic pump body. A connecting pipe is fixedly connected to one end of each oil inlet and outlet. When a leak occurs at the interface between the oil inlet / outlet and the connecting pipe, oil drips into a collection tank. The weight of the oil causes a miniature spring to deform, which in turn lowers the collection tank. The lowering of the collection tank, via a movable plate, movable rod, miniature spring, limiting plate, movable sleeve, slide groove, and slider, causes a flexible rubber block to descend, applying pressure to a pressure sensor. The pressure sensor then activates an alarm signal via a controller.

The application provides a nucleic acid detection card box and a nucleic acid detection method, which comprise sample cavities, pipetting cavities and reagent cavities arranged at intervals along the length direction of the box body; a reaction tube provided with a reaction cavity; a control valve accommodated in a valve cavity and provided with a plurality of independent pipetting flow channels, the pipetting flow channels being used for connecting one of the sample cavities, the reagent cavities and the reaction cavity with the pipetting cavity; and a pipetting driving element arranged in the pipetting cavity and capable of ascending and descending in the pipetting cavity to form positive pressure or negative pressure in the pipetting cavity.
