Title:
ONE-TOUCH TYPE QUICK COUPLER FOR CONNECTING STEEL BARS
Document Type and Number:
WIPO Patent Application WO/2013/035958
Kind Code:
A1
Abstract:
The present invention relates to a one-touch type quick coupler for connecting steel bars, including: left and right bodies (100, 200) in which both ends of the steel bars (300) are inserted and fixed; and left and right grip units (110, 210) which are provided in the inside of the left and right bodies (100, 200) to grip both ends of the steel bars (300), wherein the left and right bodies (100, 200) are formed with front steel bar insertion holes (101, 201), sidewalls (102, 202), and rear holes (103, 203), respectively, rear parts of the left and right bodies (100, 200) are coupled with each other, internal diameters of the sidewalls (102, 202) have a tapered shape with a slope, external diameter parts of the left and right grip units (110, 210) also have a tapered shape with a slope, slope parts of the left and right grip units (110, 210) are mutually operated with slope parts of the internal diameters of the sidewalls (102, 202) to perform a pressing operation for preventing the ejection of the steel bars (300) through a wedge action, saw teeth are formed in the longitudinal direction of the internal diameter parts of the left and right grip units (110, 210), and grooves (601) capable of receiving joint protrusions (301) parts of the steel bars (300) are formed at lower sides of the saw teeth (600). The present invention can reliably and stably grip the steel bars by the action of the grip units formed at the saw teeth within the coupler, reduce a manufacturing cost, and provide a remarkably competitive price by reducing consumer goods through simple production.
