Abstract
The utility model relates to a pipe joint, and belongs to the field of metal pipe fitting parts. An existing pipe joint has the defects of high cost and low firmness. The pipe joint comprises a metal tube and an external screwed joint, wherein the inner hole of the external screwed joint is divided into two sections with unequal diameters; the inner hole walls of the two sections are connected with an inclined surface; the inner hole of the section with larger diameter is positioned at one end of the external threaded joint provided with screw threads, and the wall of the inner hole of the section is provided with at least two grooves along the hole center line direction; the grooves are distributed along the circumference of the inner holes; the metal tube is penetrated through the inner hole of the external screwed joint; the outer wall of the metal tube is tightly matched with the inner hole wall of the external screwed joint; the wall of the metal tube is embedded in the grooves. According to the pipe joint, the outer wall of the metal tube is matched with the inner hole wall of the external screwed joint through punching, the binding force of the pipe joint is improved, and the cost of the pipe joint is reduced.
Description
Technical field
The utility model belongs to the metal pipe element field of components, and is especially relevant with a kind of pipe joint.
Background technique
The pipeline of automobile water circulation is connected by multistage, these pipelines generally form pipe joint by metal tube and the male connection that is arranged on pipe end, the male connection outer surface is divided into two sections, one section arranges screw thread, and one section arranges hex surface, and welding is adopted in metal tube and male connection, need to expend wlding and electric energy, cost is high, and the pipe joint fastness is not high again, and manufacturing efficiency is low.
The model utility content
The purpose of this utility model is intended to overcome the defective that cost is high, the pipe joint fastness is not high that existing pipe joint exists, and provides that a kind of cost is lower, fastness pipe joint preferably.
for this reason, the utility model is by the following technical solutions: a kind of pipe joint, comprise metal tube and male connection, it is characterized in that, the endoporus of described male connection is divided into two sections that diameter does not wait, two sections inner hole walls connect with the inclined-plane, one section endoporus that diameter is large is positioned at male connection a threaded end is set, the hole wall of this section endoporus is provided with at least twice along the groove of centerline hole direction, this multiple tracks groove circumferentially distributes along endoporus, metal tube is threaded onto the endoporus of male connection, the tube wall of metal tube and the inner hole wall of male connection closely cooperate, and the metal tube tube wall embeds in groove.
As to technique scheme replenish and perfect, the utility model also comprises following technical characteristics.
The inner hole wall of described male connection is provided with 3 road grooves.
Use the utility model can reach following beneficial effect: the utility model coordinates with the male connection inner hole wall outer wall of metal tube by punching press, the pipe joint combination force is improved, and has reduced the cost of pipe joint.
