Abstract

The utility model discloses a hose clamp which comprises a hose clamp body, a clamp shell and a knob assembly, wherein a rack is arranged on the hose clamp body, and a gear meshed with the rack of the hose clamp body is arranged on the knob assembly; the knob assembly is fixed in the hoop shell through the pressing plate, and when the knob assembly is rotated, the throat hoop body and the knob assembly move relatively through the meshing of the gear and the rack. When the hose clamp is used, the knob assembly is rotated to drive the rack on the hose clamp body to be meshed with the gear of the knob assembly, so that the hose clamp body moves to lock the pipeline, and an additional tool is not required, so that the hose clamp is more convenient to install. The knob component can only rotate in one direction and simultaneously play a role in limiting the hose clamp body by utilizing the tongue pressing and the torsion spring. When the hose clamp needs to be disassembled, only a simple tool is matched to tilt the tongue depressor, the limit of the reverse movement of the hose clamp body is released, and the hose clamp is loosened by reversely rotating the knob assembly to complete the disassembling work.
