Quick joint

Abstract

A quick connector belongs to the technical field of connectors. It includes a male joint and a female joint, which are characterized in that the front insertion part of the male joint is axially provided with at least one insertion groove and at least one withdrawal groove, and the rear ends of the insertion groove and the withdrawal groove are connected through a circumferential annular groove, The front insertion part of the female connector is correspondingly provided with snap-in protrusions; when the male connector and the female connector are connected, the snap-in protrusions snap along the insertion groove and slide into the circumferential annular groove to limit the position; the male connector and the female connector When disengaging, the snap-in protrusion rotates along the circumference to the annular groove until it exits from the exit groove. The above-mentioned quick connector only needs to be inserted in the axial direction when inserting, and the connection can be realized quickly and labor-saving; if the connection is disconnected, only the male and female connectors need to be rotated relative to each other in the radial direction. Disengagement can truly save operation time, reduce work intensity and improve efficiency.

Description

technical field [0001] The invention belongs to the technical field of joints, in particular to a quick joint. Background technique [0002] In the event of field construction, emergency rescue, refuge, etc., it may be necessary to connect and lengthen the two ropes. The usual connection methods include: knotting, screwing, steel ring buckle, steel wire or iron wire rigid hinge, etc.; on the one hand, such The connection method often requires the help of tools, and the connection speed is slow, time-consuming and laborious; and such a connection is not reliable and easy to disconnect; when an emergency occurs or an accident occurs due to unreliable connection, it may cause immeasurable losses. Invention patent CN105526309A discloses a design of a mechanical fast safety connector for ropes, which connects and disassembles ropes and rigid tension bars, and realizes the connection without tools when working in the field. It can realize the function of quick connection and quic...
