Metal quick coupling

一种金属快速接头

Abstract

本实用新型提供了一种金属快速接头,属于管件连接技术领域。它解决了现有的管接头安装便捷性不高、密封性和牢固性差等技术问题。本接头包括管套和金属材质的管体,管体两端外侧面上均设有环形的台阶面,管套的内侧面上设有圆锥面,圆锥面的小口朝向管套的内部,圆锥面的大口朝向管套的端部,管套能够套接在管体的两端并且管套的圆锥面能够挤压管体的台阶面使管体形成缩口。本接头通过设置圆锥面和台阶面的抵靠挤压使管件塑性变形,从而使管体与其内部的管件紧密接触,达到密封的效果;管套与管件能够和管体牢固的连接在一起,拆卸和装配也非常方便,不需要螺纹拧动。
The utility model discloses a metal quick coupling and belongs to the technical field of pipe fitting connection. The metal quick coupling solves the technical problems of low mounting inconvenience, bad sealing property and bad firmness of an existing coupling. The metal quick coupling comprises a pipe casing and a metal pipe body, an annular step surface is arranged on the outer lateral surface of each of two ends of the pipe body, a conical surface is arranged on the inner lateral surface of the pipe casing, the small mouth of the conical surface faces to the inside of the pipe casing while the large mouth faces to the end of the pipe casing, the pipe casing is capable of sleeving two ends of the pipe body, and the conical surface of the pipe casing is capable of extruding the step surfaces of the pipe body to enable the pipe body to neck down. The metal quick coupling enables a pipe fitting to generate plastic deformation by means of the propping extrusion of the conical surface and step surfaces so as to enable the pipe body to be in firm contact with the pipe fitting therein to realize the sealing effect; the pipe casing and the pipe fitting can be firmly connected with the pipe body, the disassembling and assembling are very convenient to perform, and the thread screwing is not needed.
