6results about How to "Guaranteed torque" patented technology

The utility model discloses refrigeration equipment with a rotating platform, and belongs to the technical field of biological experiment equipment. The refrigeration equipment with the rotating platform comprises a refrigerator, the refrigerator is provided with at least one refrigeration cavity, the refrigeration equipment further comprises a workbench slidably connected in the refrigeration cavity, the workbench is rotatably connected with a rotating shaft, the rotating shaft is fixedly connected with an overturning plate, and the overturning plate is provided with a positioning hole used for fixing a centrifugal tube; the magnetic frame is detachably mounted on the workbench and is arranged below the rotating shaft; according to the utility model, the workbench which is integrally designed with the refrigerator and can be pulled out or pushed into the refrigeration cavity is arranged, so that a centrifugal tube can be directly inserted into the positioning hole, and operations such as washing and the like can be completed by rotating and mixing the overturning plate and matching with the magnetic frame, so that the traditional operation needing to be transferred to an experiment is integrally completed; the transfer temperature fluctuation and sample pollution are avoided, and the convenience and high precision of an immune experiment are ensured.

This utility model relates to the field of cleaning machine technology, and more particularly to an overflow valve assembly tightening machine. It includes a worktable, a controller, a clamp fixed to the worktable for clamping a pump cover, and a tightening mechanism fixed to the worktable for tightening the overflow valve assembly onto the pump cover. The clamp includes a fixed plate, a clamping component fixed to the fixed plate for clamping the overflow valve assembly mounting hole on the pump cover, and a detachable positioning pin connected to the fixed plate for extending into the pump body mounting hole on the pump cover. The fixed plate has multiple pin holes for the positioning pin to extend into. The tightening mechanism and the clamping component are both electrically connected to the controller. This overflow valve assembly tightening machine has high processing efficiency and good adaptability.

The present application provides a grommet and fastening assembly. The grommet includes a body portion, a head portion, and at least one resilient arm. Each of the at least one resilient arm extends from an inner surface of one of the first and second wall portions and is deflectable at least partially toward and away from the axis. The present application provides a portion of the contact surface of the grommet for contact with the fastener by providing a deflectable resilient arm. Deflection of the resilient arm outwardly can reduce the insertion torque for inserting the fastener into the receiving passage of the grommet. Also, the receiving passage formed by the resilient arm and the inner surface of the grommet can provide sufficient retention torque for the fastener after the fastener is installed in place in the receiving passage of the grommet. Thus, even if the overall size of the grommet is small, the grommet is not easily damaged, thereby ensuring that the fastener assembly securely connects the first and second components.
