(3) summary of the invention
The purpose of this utility model is to design a kind of pipe joint that is used to connect plastic tube or metal tube, and it can overcome the deficiency of existing pipe joint, is a kind of practical new tube joint.
The technical solution of the utility model: a kind of pipe joint that is used to connect plastic tube or metal tube is characterized in that it is made of nut type body, C type retaining ring, wedge type eyelet, chamfering RunddichtringO and pipe joint body; Said pipe joint body is the jointed tubular workpieces that there is the second order boss inside; Said C type retaining ring is the ring that a sidewall leaves the diagonal cut joint gap value, and the ring periphery is the trapezoid cross section; Said wedge type eyelet inwall one end is domatic shape, the other end be with C type retaining ring ring periphery trapezoid cross section coincide little domatic, on the wedge type eyelet outer wall positive stop lug boss concentric with this eyelet arranged; Said chamfering RunddichtringO is for to hold periphery to be the seal ring of domatic shape one by one, the domatic plane that is of the domatic inwall with the wedge type eyelet of the periphery of this chamfering RunddichtringO cooperates shape, the other end of chamfering RunddichtringO is plane, and the size on this plane should be isometric with the outside boss face of pipe joint body interior second order boss; Said nut type inboard wall of tube body one end should assemble the outer wall that is fastened on the pipe joint body and according to being threaded, and the other end has and big mount inlet such as mounting pipe external diameter.
The inwall place of above-mentioned said pipe joint body is conjuncted the interior support tube parallel with the pipe joint body wall, between the inboard boss sidewall of interior support tube outer wall and pipe joint body for inserting the amount of space of connecting tube.
The above-mentioned said pipe joint that is used to connect plastic tube or metal tube can be lead directly to, various ways such as elbow, threeway or four-way.
Use installation process of the present utility model: between the inwall of pipe joint body, put into the chamfering RunddichtringO, it is domatic upwards, again wedge type metal snare is put into, it is domatic downwards, coincide with making progress of chamfering RunddichtringO is domatic, the fastening ring set of C type is put into, last, the outside puts the nut type body according to screw threads for fastening again.When connected tube insertion tube joint, tightening nuts type body, under the pressure of nut type body, C type retaining ring between pipe joint body and nut type body, wedge type eyelet, chamfering RunddichtringO are closely pushed, connected tube is connected with the pipe joint body, at this moment, fastening, sealing is finished in the lump.
Superiority of the present utility model is: 1, wedge type eyelet and chamfering RunddichtringO form good sealing structure; 2, when operation, the outside of wedge type eyelet can be ended by body, makes the chamfering RunddichtringO can tension or destroyed; 3, C type retaining ring has good fastening effect to plastic tube or metal tube; 4, this pipe joint is easy to use, makes connecting tube connect total quality and improves, and can reuse; 5, when connecting plastic tube or metal tube, easy to operate, good airproof performance.
