Three-way joint of protection net

Abstract

The invention discloses a three-way joint of a protection net. The three-way joint comprises a nylon three-way joint body, wherein the nylon three-way joint body is provided with three sections of joints used for connecting the border of the protection net; the three sections of joints are respectively provided with an inner hole, and the three inner holes are mutually communicated; a metal plate is respectively inserted in each inner hole; and the three metal plates are tightly connected. The three-way joint of the protection net has the advantages of reliable connection, high safety coefficient, strong anti-theft capacity, simple structure, convenient manufacture and low cost.

Description

technical field [0001] The invention relates to an assembly accessory of a window protective net or a balcony protective net, in particular to a protective net tee joint. Background technique [0002] The three adjacent frames of the protective net are usually connected by three-way joints. Most of the existing three-way joints of the protective net are made of nylon material. The three-way joints made of this material are prone to aging after long-term use. When the aging is serious, it will cause The detachment of the adjacent three sections of the frame makes the protective net lose its protective effect. If the protective net using this tee joint is used as the window protective net, there will be serious safety hazards; at the same time, the tee made of this material The joints have poor high temperature resistance, and they are easy to soften and melt when they are roasted by fire. Criminals who understand this defect can easily destroy the protective net using this ki...

Problems solved by technology

[0002] The three adjacent frames of the protective net are usually connected by three-way joints. Most of the existing three-way joints of the protective net are made of nylon material. The three-way joints made of this material are prone to aging after long-term use. When the aging is serious, it will cause The detachment of the adjacent three sections of the frame makes the protective net lose its protective effect. If the protective net using this tee joint is used as the window protective net, there will be serious safety hazards; at the same time, the tee made of this material The joints have poor high temperature resistance, and they are easy to soften and melt when they are grilled by fire. Criminals who understand this defect can easily destroy the protective net using this kind of three-way joint. The anti-theft ability of this protective net is very poor.

In order to solve the problems existing in the tee joints made of existing nylon materials, tee joints made of metal materials or other new anti-aging and high temperature resistant materials have appeared on the market. Although this tee joint is not easy to age, it is also fire-resistant Good performance, but its toughness is poor. When 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 the production of the protective net.
