Description
Technical field
The present invention relates to be used for the assembling fittings that tubing connects, relate in particular to two pass joints that are used for the tubing connection.
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; Two sections adjacent frame places of protective screening are usually with the connection of two pass joints, and two pass joints of existing protective screening are to adopt nylon material to make mostly, are easy to generate aging after the long-term use of two pass joints of this material system; Will cause the disengaging of adjacent two sections frames when aging serious; The protective screening that will adopt this two pass joints make protective screening lose protective action, if will exist serious potential safety hazard so as the forms protective screening; Simultaneously; Two pass joint heat-resisting abilities of this material are poor; Burnt roasting just softening easily, fusing, the lawless person who understands this defective can destroy the protective screening that adopts this two pass joints very easily, and the anti-theft capability of this protective screening is very poor.For the problem that two pass joints that solve existing nylon material making exist, metal material or two pass joints that other novel anti is aging, exotic material is made have appearred adopting in the market, though this two pass joints are difficult aging; And refractoriness is good, but its poor toughness, when being used as the frame connection of protective screening; Frame is prone to loosening; And this material all is a precious materials, has increased the cost of production of two pass joints and protective screening, and inconvenience is widely applied in the middle of the protective screening generation.
Publication number is that the Chinese patent document of CN101942958A discloses a kind of protective screening two pass joints; Comprise nylon two pass joint bodies; Nylon two pass joint bodies are provided with two sections joints that are used to connect the frame of protective screening, and two sections joints are respectively equipped with an endoporus, and two endoporus are interconnected; Each endoporus all inserts a metal sheet, and two metal sheets are fastenedly connected.This protective screening two pass joints, after nylon was partly aging, the frame of protective screening still connected through two metal sheets, avoided the frame of adjacent protective screening to break away from, and had improved the connection reliability of the frame of protective screening greatly; After softening, melting, metal sheet still is not affected to the connection of the frame of protective screening when nylon part quilt baked wheaten cake is roasting, and protective screening can be destroyed easily, has strengthened anti-theft capability; Have and the same toughness of common nylon two pass joints, make the connection of frame of protective screening fastening reliable, the phenomenon that can not occur becoming flexible.But its two metal sheets need form through securing member and interconnect, and receive torsion and when producing distortion, will influence the bonding strength of securing member as metal sheet, when this distortion occurs repeatedly, then might cause the connection of securing member to lose efficacy; When mounted, two metal sheets must connect through the securing member more than two, can prevent that so just metal sheet from producing relative rotation, and guarantee bonding strength, but this makes fitting operation complicated, has increased human cost, 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.
Summary of the invention
The technical problem that the present invention will solve is: to the technical problem that prior art exists, provide a kind of connect reliable, safety factor is high, simple in structure, be convenient to make, with low cost be used for two pass joints that tubing connects.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of two pass joints that are used for the tubing connection; Comprise nylon two pass joint bodies; Said nylon two pass joint bodies are provided with connecting portion and two sections joints that are used to be connected said tubing; Said two sections joints extend to both direction from connecting portion; Offer the slot that extends to two sections joints from connecting portion on the said nylon two pass joint bodies, be inserted with the monolithic metal sheet that extends to two sections joints from connecting portion in the said slot, said connecting portion is coated with the metal valve jacket that can hide slot and monolithic metal sheet.
As further improvement of the present invention:
Said monolithic metal sheet is a L shaped plate.
Said slot and said monolithic metal sheet profiling are provided with.
Said metal valve jacket and said connecting portion clamping.
Said metal valve jacket comprises two angles cover, and said angle cover is made up of an interior angle baffle plate and three orthogonal panels, one of them panel be provided with can with the trip of adjacent two tubing clampings, said interior angle baffle plate is connected with this panel.
Said connecting portion is provided with the trip storage tank, and said trip places the trip storage tank.
Be respectively equipped with dovetail on two other panel of said angle cover, said two dovetails are arranged in parallel, and are equipped with dovetail groove on two lateral surfaces of said connecting portion, and dovetail is inserted in the corresponding dovetail groove.
Compared with prior art, the invention has the advantages that:
Two pass joints that are used for the tubing connection of the present invention; On nylon two pass joint bodies, offer the slot that extends to two sections joints from connecting portion, be inserted with the monolithic metal sheet that extends to two sections joints from connecting portion in the slot, when these valve jacket formula two pass joints are used for the connection of protective screening tubing; Can tubing, nylon two pass joint bodies and monolithic metal sheet three be connected as a single entity through securing member; Make its all advantages that possess existing nylon structure of steel pole two pass joints, in installation process, need not simplify installation steps greatly through the metal sheet of securing member connection separated body formula; Saved the manpower and materials cost; And, to have eliminated split type metal sheet fully and might occur connecting the potential safety hazard that inefficacy brings, safety further improves; Simultaneously; The connecting portion of nylon two pass joint bodies is coated with the metal valve jacket; This metal valve jacket not only can hide slot and monolithic metal sheet, makes that the protective screening after the assembling has good whole property, and makes the whole protection netting gear be equipped with unified metal-like; And be convenient to the metal valve jacket paintedly, make it to form optimal collocation of colour with the frame of protective screening.The monolithic metal sheet is a L shaped plate, and this L shaped metal sheet is directly processed through bending technology, and it is simple in structure; It is convenient to peg graft, and is convenient to install, and the slot of profiling setting also possesses same simple structure with it simultaneously; Be convenient to nylon two pass joint bodies are carried out the mould design, reduce die cost.Two angle covers of metal valve jacket all are connected convenience quick for installation through snap fit with connecting portion.
