Japanese Patent JP2560248
Kind Code:
Y2
Abstract:
A tube coupler has a main tubular socket body connected to a first tube, a main tubular plug body connected to a second tube and removably connected to the main tubular socket body, and a locking mechanism for locking together the main tubular socket body and the main tubular plug body in a state in which the main tubular plug body is inserted in the main tubular socket body. The tube coupler further includes an operating ring threadably engaging the outer peripheral surface of the main tubular socket body, a slide ring mounted on the outer peripheral surface of the main tubular socket body and being moved axially by the operating ring, and a cylindrical holder slidably fitted in the main tubular socket body and engageable with the main tubular plug body. The holder has a groove open radially outward, and the main tubular socket body has axially elongated holes. The slide ring is provided with pins each having a distal end portion extending into the groove through the corresponding elongated hole. Each pin moves the holder in the same direction as the direction of the movement of the operating ring when the operating ring is moved toward the main tubular plug body, such that the pins press the main tubular plug body.
