The purpose of this utility model is achieved through the following technical solutions: the device that can improve the switching efficient of centrifugation apparatus upper end cover, comprise centrifugal cylindrical shell and the end cap that is connected with centrifugal cylindrical shell, be provided with fixed mount one and fixed mount two on the outer wall of described centrifugal cylindrical shell, and fixed mount one and fixed mount two are arranged on the same plumb line, fixed mount one is arranged on the top of fixed mount two, described end cap is connected with installing plate, and installing plate is connected with joint pin, fixed mount one is connected with installing plate, and fixed mount two is connected with joint pin.
Further, the quantity of described fixed mount one and installing plate is two, and two fixed mounts one are arranged on the sustained height on the centrifugal cylindrical shell, be provided with connecting pin between the fixed mount one, and the two ends of connecting pin are passed respectively corresponding fixed mount one and installing plate follower head and are sheathed with nut, installing plate can rotate around connecting pin, and fixed mount one all is arranged between the installing plate.
Further, the end that described joint pin is connected with installing plate is provided with boss, and the end face indent of boss forms groove, installing plate one end is arranged in the groove, be provided with pin in the groove, and pin pass installing plate after its two ends pass respectively boss, installing plate can rotate around pin.
Further, be 30 ° to 60 ° angle between the line between the center of the center of described connecting pin and pin and the horizontal plane.
Further, be 45 ° angle between the line between the center of the center of described connecting pin and pin and the horizontal plane.
In sum, the beneficial effects of the utility model are: this device simple in structure, by being connected of installing plate and connecting pin, end cap is installed on the centrifugal cylindrical shell rapidly, realized semi-automatic operation, reduce operating personnel's labour intensity, improved the efficient that opens and closes, guaranteed the centrifuge dripping quality of copper powder liquid.
