ONE-TOUCH TYPE NUT, CAPABLE OF ENHANCING WORKABILITY BY FIXING A BOLT TO A COUPLING TARGET OBJECT WITH A ONE-TOUCH MODE

摘要

PURPOSE: A one-touch type nut is provided to couple a bolt to a coupling target object without spinning the bolt even though a female screw thread is not formed on the coupling target object.;CONSTITUTION: A one-touch type nut comprises a bolt body(10), a guide groove(20), and a fixing ring(30). The bolt body includes a coupling protrusion unit(11) capable of being inserted into a bolt insertion hole(N1). The fixing ring of a C-shape is insert-coupled with the guide groove. A diameter of the fixing ring becomes larger when the rod bolt body is inserted into inside of the fixing ring by an external force as the fixing ring becomes widen by being rubbed with the outer periphery of the rod bolt body, and the widened diameter of the fixing ring is restored by elasticity so that the fixing ring fixes the rod bolt body. The guide groove is formed into a spiral shape in the inner periphery of the boy along a circumferential direction. A plurality of C-shaped rings of the fixing ring is insert-coupled with the guide groove continuously and independently and forms a male screw thread.;COPYRIGHT KIPO 2013
