Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of fitness equipment, in particular to a power station. Background Art
[0002] In some fitness equipment, a cable reel is used for tension resistance training. For example, a cable reel is used in a pull-type rowing machine. The pull-type rowing machine in the prior art is usually equipped with a cable reel. The pull rope of the cable reel is connected to a pull rod. When the pull rod is pulled, the pull rope is pulled out. When the pull rope is pulled out, the cable reel rotates and tightens the coil spring in the cable reel. When the cable reel rotates, it also drives the wheel to rotate. The wheel is linked to the damping wheel, causing the damping wheel to rotate as well. The damping wheel in turn produces a damping effect when the user pulls the pull rod. When the user relaxes the pull rod, the coil spring resets, and the cable reel rotates in the opposite direction to reel in the pull rope. During the pulling and returning process, the user cooperates with the sliding of the bottom seat to form an action that imitates rowing.
[0003] In order to meet the training needs of different groups of people, the damping size on the reel can be adjusted according to needs. The traditional damping adjustment method is not convenient enough, and some also require the use of motor equipment for assistance, which increases the training cost. Utility Model Content

At this time, the cam 108 at the bottom contacts the first protrusion 1142 on the bottom movable block 114, and the other cams 108 do not contact the movable block 114. After the bottom movable block 114 moves, the latching tooth 1141 disengages from the damping wheel 105, so that the damping wheel 105 rotates together with the connecting shaft 104, reducing the damping received by the pulley 119 when it rotates; when the turntable 103 is rotated 30 degrees again, the turntable 103 drives the installation shaft 107 to rotate again, and the installation shaft 107 drives all The damping wheel 105 rotates, and the second cam 108 from the bottom up on the mounting shaft 107 contacts the first protrusion 1142 on the second movable block 114 from the bottom up. The cam 108 at the bottom is still in contact with the first protrusion 1142 on the bottom movable block 114. The other two cams 108 are not in contact with the movable block 114. The two damping wheels 105 at the bottom rotate together with the connecting shaft 104, reducing the resistance to the rotation of the pulley 119 again, thereby adjusting the pulling force of the pull ring 102; if further adjustment is still needed, the turntable 103 can be rotated again to continue adjusting. The pulling force of the pull ring 102 can be adjusted quickly and conveniently without the need for setting up electronic drive components, thereby reducing training costs.
