Both ends of the grip rod are assembled with flange driving members, the planetary gear system includes an outer casing, through the installation mode that the flange driving member is engaged with the planetary gear system, the planetary gear mechanism is disposed enclosedly, and a load-bearing iron ring is also disposed in the planetary gear system to play a load-bearing and limiting effect on the planetary carrier.

Abstract: The present invention relates to an adjustable dumbbell, which includes a dumbbell body and dumbbell pieces cumulatively attached to both ends of the dumbbell body, wherein the dumbbell body includes a grip rod and mounting portions, further includes a first telescopic rod and a second telescopic rod, the number of dumbbell pieces hanging on the first telescopic rod and the second telescopic rod is controlled by the first telescopic rod and the second telescopic rod extending from or retracting into both ends of the dumbbell body in opposite directions, thereby adjusting the weight of dumbbells. The first telescopic rod and the second telescopic rod are disposed in a semicircular shaft shape, and the first telescopic rod and the second telescopic rod are staggered, so that the lengths of the first telescopic rod and the second telescopic rod are doubled, and the number of adjustable dumbbell pieces is greatly increased.

Abstract: The present invention relates to an adjustable dumbbell, which includes a rotatably disposed grip rod and a locking element, wherein a locking portion is disposed at both ends of the grip rod, the locking element includes a base, a movable pin and a compression spring, the movable pin is slidably disposed in the base, the base is provided with a first spring sleeve column, the movable pin is provided with a second spring sleeve column, and both ends of the compression spring are respectively sleeved and positioned on the first spring sleeve column and the second spring sleeve column. In the present invention, the base and the movable pin are both provided with the spring sleeve column, which is not only convenient to mount and position the compression spring during assembly, but also can prevent the compression spring from falling out due to the shaking of dumbbells in use.

Abstract: The present invention relates to a dumbbell and especially relates to an improvement on an assembly mode of a grip rod and flanges at both ends thereof in the dumbbell.

Abstract: A service level management document is modeled by a multi-path, navigable graph. The graph is comprised of nodes connected by lines where each node represents part of a modeled service level management document and each line represents the relationship between connected nodes. Each node has a predetermined shape that corresponds to the role of each node in the graph, such as by designating whether the node is a root node, branch node, leaf node, or branch graph node. Moreover, the shape can distinguish whether the node is optional or required. The background color of each node is indicative of the state of the information within a configuration page linked to a corresponding node. The configuration pages of a graph collectively describe the content of the modeled service level management document.

The system receives a first input that selects a particular time period from the plurality of time periods, and further monitors the execution time of the plurality of tasks in the selected time period. The system receives a second input that selects a particular task from the particular time period, and monitors the execution time of the particular task in the particular time period.

Abstract: A next task in a queue of tasks is considered for execution. In response to the next task having no dependent tasks, executing the next task. In response to the next task having dependent tasks, wherein the dependent tasks have been executed, executing the next task. In response to the next task having dependent tasks that have not completed execution, placing the next task into the set of waiting tasks. In response to placing the next task into the set of waiting tasks, determining if each dependent task of the next task is in the set of unfinished dependent tasks, placing each dependent task of the next task that is not in the set of unfinished dependent tasks into the set of unfinished dependent tasks, and establishing a link between the next task and each of its dependent tasks in the set of unfinished dependent tasks.
