Abstract: An adjustable wind resistance device is provided, which includes a wind wheel, a housing component, and a driving device. The housing component includes a wind chamber, an air inlet, and an air outlet. The housing component includes a fixing wind disc and a movable wind disc. The fixing wind disc forms a first air inlet, the movable wind disc forms a second air inlet. The driving device is fixedly connected to the fixing wind disc and drives the movable wind disc to rotate to adjust an area of the air inlet. A rowing machine is provided, which includes the adjustable wind resistance device and an operating component, the operating component includes a handle and a transmission component. The present disclosure adjusts the system impedance of the wind resistance device by providing the movable wind disc to regulate the area of the air inlet, achieving dynamic adjustment of wind resistance.

Abstract: A treadmill running platform structure is provided, which includes a running platform, a running board, and a running belt. The running board includes two soft elastic strips adapted to two side bars of the running platform, a plurality of rigid support strips provided between the soft elastic strips, and strip-shaped connection plates respectively connected to two ends of the rigid support strips. Two strip-shaped connection plates are connected above the rigid support strips, and the strip-shaped connection plates are respectively fixed to a corresponding end of each rigid support strip. The present disclosure can achieve buffering of the entire running board, especially by connecting the rigid support strips together through the strip-shaped connection plates, thereby avoiding an uneven transition of the rigid support strips when a runner steps on the running board, improving the comfort of the runner's feet, and reducing the noise of the treadmill.

Abstract: The present invention relates to a resistance regulation braking device and a using method thereof. A stationary shaft, a wire grip, and a rotary mandrel assembly are mounted on a frame. A rotary sleeve is mounted at an upper end of the stationary shaft. A driving member is arranged between the rotary sleeve and the mandrel. An elastic slider is arranged on the stationary shaft, and is located below the rotary sleeve. A lower magnetic part is arranged on the elastic slider. An upper magnetic part arranged opposite to the lower magnetic part is arranged on the rotary sleeve. The device is not only wide in resistance regulation range, but also high in resistance regulation precision, and has various resistance regulation means.

Abstract: A stabilizer folding structure and a handheld stabilizer. a stabilizer folding structure for rotationally connecting the motor base and the rocker arm such that the motor base and the rocker arm have an unfolded first state and a stored second state during relative rotation, comprising: an elastic member, applying An elastic force for abutting the motor base and the rocker arm; and a snap structure at a position where the motor base abuts the rocker arm, in the first state and the second state, The snap structure is engaged to restrict relative rotation of the motor base and the rocker arm. In other states, the snap structure is disengaged such that the motor base and the rocker arm are relatively rotatable. The folding structure of aspects of the invention facilitates the folding and storage of the stabilizer, and is convenient for the user to use.

Abstract: A clamping mechanism comprises: a main body; a pair of clamps are arranged on the main body, and each clamp may be moved along the clamping main body thereof the holding direction reciprocates relative to the main body; the clamping width maintaining mechanism is disposed on the main body for maintaining the clamping width of each pair of clamps to be adapted to the photographing device to be clamped; the adjusting mechanism is disposed on the main body for adjusting the spacing between one of each pair of clamps and the main body in the clamping direction for adjusting the clamping center of each pair of clamps while maintaining the clamping width of each pair of clamps relative to the center of the subject.
