  We report small-scale magnetic flux ropes via the Parker Solar Probe in situ
measurements during the first six encounters and present additional analyses to
supplement our prior work in Chen et al. 2021. These flux ropes are detected by
the Grad-Shafranov-based algorithm with the duration and scale size ranging
from 10 seconds to $\lesssim$1 hour and from a few hundred kilometers to
10$^{-3}$ au, respectively. They include both static structures and those with
significant field-aligned plasma flows. Most structures tend to possess large
cross helicity, while the residual energy distributes in wide ranges. We find
that these dynamic flux ropes mostly propagate anti-sunward, with no
preferential sign of magnetic helicity. The magnetic flux function follows a
power law and is proportional to scale size. We also present case studies
showing reconstructed two-dimensional (2D) configurations, which confirm that
the static and dynamic flux ropes have the common configuration of spiral
magnetic field lines (also streamlines). Moreover, the existence of such events
hints at the interchange reconnection as a possible mechanism to generate flux
rope-like structures near the Sun. Lastly, we summarize the major findings and
discuss the possible correlation between these flux rope-like structures and
turbulence due to the process of local Alfvenic alignment.
