AI Technical Summary

Technical Problem

Conventional clamps for securing hoses and pipes in vehicles have high manufacturing costs due to numerous separate parts, are prone to part loss, and suffer from deformation during tightening, leading to reduced fastening force and inability to reuse.

Method used

A clamp design integrating a band, washer, and nut sections into a single unit, featuring perforations, connecting sections, and support elements to prevent deformation and enhance fastening force, allowing reuse.

Benefits of technology

Reduces manufacturing costs and weight, minimizes part loss, and maintains airtightness by suppressing deformation during tightening, enabling repeated use and improved appearance.

Abstract

Clamping device comprising: a strip section (100) that is configured to surround a predetermined element (3); a nut section (200) and a washer section (300), each integrally formed at opposite ends of the strip section (100) and bent outwards and facing each other; and a bolt (400) which passes through and engages with the nut section (200) and the washer section (300) and is configured to decrease or increase the diameter of the band section (100) during rotation, characterized by the fact that an end section of the bolt (400) comprises an extended section (420) with a diameter that is smaller than the diameter of the thread of the bolt (400), wherein the washer section (300) has a washer hole (310) through which the extended section (420) passes, and wherein one end of the extended section (420) has a head section (430) with a diameter larger than the diameter of the washer hole (310) to prevent the bolt (400) from being removed from the washer hole (310), wherein the washer hole (310) is formed in an oval which extends in a longitudinal direction of the washer section (300).
