The utility model discloses a lock unit, adjusting mechanism and spacing sub -
assembly relates to the technical field of automobile parts to at least solve the existing
pickup truck tail box cover and the connecting
assembly of car body insufficient constraint to multidirectional displacement, resulting in the problem that the
tail box cover is easy to displace or deflect in the
vehicle driving, including lock tongue, be configured as limit the
relative displacement of
pickup truck tail box with tail box cover in third direction, adjuster, with Lockable connection with lock tongue, be configured as change the contact range of lock tongue with
pickup truck tail box,
fender, be configured as limit the
relative displacement of
pickup truck tail box with tail box cover in second direction or first direction. Through the combination design of lock tongue limit third direction displacement and
fender limit second direction displacement, realize the double restraint of tail box cover in transverse and longitudinal, cooperate with the locking structure of vertical direction, form three -dimensional spacing
system, effectively prevent the displacement or deflection of cover body in the
vehicle driving.
