Three-way joint for connecting pipes

Abstract

The invention discloses a three-way joint for connecting pipes, consisting of a nylon three-way joint body and three metal pieces, wherein the nylon three-way joint body is provided with three sections of joints for connecting the pipes; the three sections of joints are respectively provided with an inner hole; three inner holes are mutually communicated and are respectively provided with one metal piece in an inserting manner; each metal piece comprises a base part and a penetrating-inserting connecting part; and all the three metal pieces are connected in a penetrating and inserting manner to form a whole body by respective penetrating-inserting connecting parts. The three-way joint has the advantages of simple structure, convenient installation, low cost, and great improvement on connection strength and safety factor.

Description

technical field [0001] The invention relates to an assembly fitting for pipe connection, in particular to a tee joint for pipe connection. Background technique [0002] The protective net is a common pipe assembly product. Its frame is generally assembled with pipes, tee joints and two-way joints. The three adjacent frames of the protective net are usually connected with three-way joints. The tee joint of the existing protective net Most of them are made of nylon material. The tee joint made of this material is prone to aging after long-term use. When the aging is serious, it will cause the separation of the adjacent three sections of the frame, making the protective net lose its protective effect. If this kind of tee joint is used If the protective net of the joint is used as a window protective net, there will be serious safety hazards; at the same time, the tee joint made of this material has poor high temperature resistance, and it is easy to soften and melt when it is r...

Problems solved by technology

However, the metal plate structure is relatively thin, low in strength, and poor in bending resistance; the three metal plates are connected by only two fasteners, and when a metal plate is deformed by torsion, it will affect the fastener. Connection strength, when this deformation occurs repeatedly, it may cause the connection failure of the fasteners; when installing, the three metal plates must be connected by more than two fasteners, so as to prevent the relative rotation of the metal plates , to ensure the connection strength, but this makes the installation operation complicated, increases the labor cost, and reduces the assembly efficiency
