Description
Technical field
The present invention relates to the assembling fittings for the tubing connection, relate in particular to the tee junction that connects for tubing.
Background technology
Protective screening is a kind of common tubing completed knocked down products, its frame generally adopts tubing, tee junction and two pass joints to assemble, three sections adjacent frame places of protective screening connect with tee junction usually, the tee junction of existing protective screening is to adopt nylon material to make mostly, the tee junction of this material system is long-term to use rear easily generation aging, will cause the disengaging of adjacent three sections frames when aging serious, make protective screening lose protective action, if will adopt the protective screening of this tee junction as the forms protective screening, will have serious potential safety hazard so; Simultaneously, the tee junction heat-resisting ability that this material is made is poor, burnt roasting just easily softening, fusing, the lawless person who understands this defective can destroy the protective screening that adopts this tee junction very easily, and the anti-theft capability of this protective screening is very poor.In order to solve the problem of the tee junction existence that has the nylon material making now, the tee junction that employing metal material or other Novel anti-ageing, exotic material making have occurred in the market, although this tee junction is difficult for aging, and refractoriness is good, but its poor toughness, when being used as the frame connection of protective screening, frame is easily loosening, and this material all is precious materials, has increased the cost of production of tee junction and protective screening, and inconvenience is widely applied in the middle of the protective screening generation.
Publication number is that the Chinese patent literature of CN101942959A discloses a kind of Three-way joint for protection net, comprise the nylon three-way joint body, the nylon three-way joint body is provided with three sections joints that are used for the frame of connection protective screening, three sections joints are respectively equipped with an endoporus, three endoporus are interconnected, each endoporus all inserts a metal sheet, and three metal sheets are fastenedly connected.This Three-way joint for protection net, after nylon was partly aging, the frame of protective screening still connected by three metal sheets, avoided the frame of adjacent protective screening to break away from, and had greatly improved the connection reliability of the frame of protective screening; Burnt roasting and after softening, melting, metal sheet still is not affected to the connection of the frame of protective screening when nylon part, make the protective screening can be not destroyed easily, strengthened anti-theft capability; Have the toughness the same with common nylon three-way joint, make the connection of frame of protective screening fastening reliable, the phenomenon that can not occur becoming flexible.But its three metal sheets need to form by securing member and interconnect, and when producing distortion when there being metal sheet to be subjected to torsion, will affect the bonding strength of securing member, when this distortion occurs repeatedly, then might cause the Joint failure of securing member; When mounted, three metal sheets must connect by the securing member more than two, can prevent that so just metal sheet from producing relative rotation, and guarantee bonding strength, but this have increased human cost so that fitting operation is complicated, has reduced packaging efficiency; In addition, this kind tee junction outside the connecting portion of tee junction is exposed to, can't form unification with after the frame of protective screening is connected with metal edge frame.
