Three-way square joint for pipe connection

Abstract

The invention discloses a three-way square joint for pipe connection. The three-way square joint comprises a three-way joint body with three sections of square joints for connecting pipes. An entire metal plate wraps the outside of the three-way joint body along three long edges, and is extended to the three sections of square joints. The three-way square joint for the pipe connection has the advantages of simple structure, convenience for manufacture, high connection strength and great improvement in bearing capacity, bending resistance and flexural strength.

Description

technical field [0001] The invention relates to pipe assembly technology, in particular to a three-way square joint used for pipe connection. Background technique [0002] Most of the existing tee joints are made of nylon material. The tee joints made of this material are prone to aging after long-term use. The window protective net will have 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 grilled by fire. The protective net of this kind of three-way joint is destroyed, and the anti-theft ability of this kind of protective net is very poor; the existing three-way joint is also made of metal materials or other new anti-aging and high-temperature resistant materials, although this kind of three-way joint is not easy to age , and has good fire resistance, but its toughness is poor. When it is used as the frame connection of the protective net, the frame is easy to l...

Problems solved by technology

[0002] Most of the existing tee joints are made of nylon material. The tee joints made of this material are prone to aging after long-term use. The window protective net will have 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 grilled by fire. The protective net of this kind of three-way joint is destroyed, and the anti-theft ability of this kind of protective net is very poor; the existing three-way joint is also made of metal materials or other new anti-aging and high-temperature resistant materials, although this kind of three-way joint is not easy to age , and has good fire resistance, but its toughness is poor. When it is used as the frame connection of the protective net, the frame is easy to loosen, and this material is a precious material, which increases the production cost of the tee joint and the protective net, and is inconvenient to be widely used in production. among

In order to solve the above-mentioned problems existing in the existing tee joints, a tee joint based on nylon tee joints and adding metal plates has appeared on the market. This kind of tee joints not only greatly improves the strength and safety, but also has moderate cost. , the frame is not easy to loose, and has been widely used. However, due to the relatively simple setting of the metal plate, this kind of tee joint still has a lot of room for improvement in its strength and bearing capacity.
