Band winding type hose clamp

A band winding type hose clamp comprising:

• a body fixedly engaged with one end of a band;
• a winder rotatably coupled to the body, the winder receiving the other end of the band surrounding an outer periphery of a hose and winding the other end of the band in accordance with rotation thereof by external force, thereby causing the band to come into close contact with the outer periphery of the hose while pressing the outer periphery of the hose;
• and
• a cover pivotably coupled to a portion of the body spaced apart from the winder such that one end of the cover can engage with the winder, the cover selectively restraining rotation of the winder, thereby maintaining elastic force of the band pressing the outer periphery of the hose,
• wherein the body comprises a base, at which one end of the band is disposed, a pair of coupling parts respectively installed at opposite lateral edges of the base while being erected upwards, insertion holes respectively formed at the coupling parts, to rotatably receive the winder, hinge insertion holes formed at the coupling parts while being spaced apart from the insertion holes, respectively, such that the cover is pivotably coupled to the coupling part by a hinge shaft, and at least one band coupling slot formed at a predetermined inside position of the base such that the band is inserted into the base from an outside or inside of the base through the band coupling slot and is engaged with the base through bending thereof,
• wherein the body comprises upper protrusions formed at an end of the base spaced apart from the band coupling slot, to protrude outwards and upwards, and elastic members each connected to a corresponding one of the upper protrusions and the cover at one end and the other end thereof, respectively, to provide elastic force to the cover pivotably coupled to the hinge insertion holes, thereby limiting pivotal movement of the cover.
