HOSE CLAMP

摘要

A hose clamp includes a band and a worm drive mechanism. The band has a set of slots located between a first and second circumferential end of the band. The worm drive mechanism is connected to the band and causes radial contraction of the band to tighten the band. The worm drive mechanism includes a screw that engages the set of slots for radial contraction of the band. A clamping-pressure-restoring construction is provided in order to maintain a seal between the hose clamp and an underlying hose during use of the hose clamp and when the underlying hose experiences size expansion and contraction due to, for example, temperature fluctuations.

主权项

1. A hose clamp, comprising:
a band having a first circumferential end, a second circumferential end, and a plurality of slots located between said first and second circumferential ends, said band having a first axial end and a second axial end, said first and second circumferential ends and said first and second axial ends being defined relative to a generally circular shape presented by said band during use of the hose clamp, in axial sectional profile between said first and second axial ends said band having a first curved section, having a second curved section, and having a flat section extending between said first and second curved sections, said band having a pocket residing at an underside of said band and at least partly defined by said first and second curved sections and by said flat section; and a worm drive mechanism connected to said band and operable to radially contract said band during a tightening action of the hose clamp, said worm drive mechanism including a screw with an at least partially threaded shank that engages said slots of said band upon rotation of said screw to cause the radial contraction of said band, the connection between said worm drive mechanism and said band involving a hook with an end portion located at said pocket.
