Abstract

Provided is a hose coupler, comprising an end part, a side wall, clamp pins, a stop part, a buckle part and a port. The side wall is located below the end part, with the lower part being hollow. With a triangular shape, the six clamp pins are located at the inner edge of the side wall in a manner to be perpendicular to the side wall. The buckle part is located on the outer central part of the side wall. The stop part is located at the lower end of the side wall. The port is located at the center of the end part and has a hollow circular shape. The hose coupler is used for fixing a metal hose on a device casing. The metal hose has continuous protruding parts. The device casing is provided with a fixing hole. Each of the six clamp pins is clamped between the two adjacent protruding parts of the metal hose. The buckle part abuts against the inner side of the device casing, and the stop part abuts against the outer side of the device casing. The diameter of the port is smaller than that of the metal hose, but greater than that of a threaded electric wire/cable. According to the utility model, the clamp pins of the hose coupler can be attached to a thread line of the metal hose to the maximum extent, and therefore are not likely to come off after being mounted to the hose, with the hanging-force bearing capacity as high as 70LB, thereby making installation easy and satisfying the fix and stress requirements.
