Abstract

The utility model relates to a pipe joint, which comprises a joint body composed of a housing 3, a core pipe 4 arranged in the housing 3 and a pipe body 1 plugged between the housing 3 and the core pipe 4, a flowering sleeve 5 and a screw-thread sleeve pipe 6, wherein, screw threads are arranged on the inner side wall of the pipe body and next to the port of the pipe body, the inner end of the pipe body forms a truncated-cone shape, and the pipe body opposite to the housing 3 and the core pipe is fixed; the bottom end of the flowering sleeve 5 is provided with a leakproof bottom ring 8 with a hook port 9, the outer side wall of the flowering sleeve 5 forms a truncated-cone shape, and the upper end of the inner hole wall of the flowing sleeve 5 is provided with an anti-slide dummy club 10; the outer side wall of the screw-thread sleeve pipe 6 is provided with screw threads. When the novel pipe joint is fixedly tightened and is used for preventing pipes to be connected from leaking, the pipes to be connected don't need to be applied with large pressure, so the pipes to be connected can not be deformed.

Description

A kind of pipe joint
The utility model relates to pipe connection, particularly a kind of pipe joint.
Existing pipe joint has that utilizing is threaded is connected two kinds with non-threaded, for the pipe that can not open screw thread as aluminium-plastic composite pipe etc., the pipe joints that adopt with the sealing of O type more, this kind pipe joint must apply external force the O RunddichtringO is pressed on realization sealing on the body when connecting, but in order to compress the O RunddichtringO, body is deformed, the plastics of extrusion are aging easily, and aging stratification will take place the aluminium plastic composited tube of heat processing and forming, cause the body seepage.
The purpose of this utility model provides a kind of pipe joint of the O of need not RunddichtringO.
The purpose of this utility model is to realize like this, this new tube joint comprises adapter body, Sealing and fixing device, different is: described body is by shell and place the core pipe of shell and fill between shell and core pipe, and constitutes with shell, the relatively-stationary body of core pipe; Near the end, have screw thread on the inner hole wall of described body, and be the truncated cone inclined-plane near the inner end; Described Sealing is the truncated cone cover of blooming, and the tapering of its outer side surface and body inner hole wall are corresponding near the truncated cone that the inner end is; Described fixing device is a threaded sleeve, offer on the outer side wall of this threaded sleeve with the body inner hole wall on offer the corresponding screw thread of screw thread, stay between its inner hole wall and the core tube wall and can hold the slit of waiting to take over body.
Because this new tube joint is when connecting body, body to be taken over is in the core pipe and blooms between the cover, when threaded sleeve and body screw, threaded sleeve pushes the cover of blooming, make it to wait to take over and press to the core pipe and Yin Ding and sealing, need not bear external force owing to wait to take over, more need not distortion, then can not make and wait to take over aging seepage.And the cover bottom is provided with the effect that O-ring seal can be played in the leakproof foundation ring because bloom, and again because outside the interior ring of leakproof foundation ring, the mouth of hook 9 that has a circle to protrude inwards can hook and wait to take over the body inwall, has more strengthened treating the leakproof of taking over body.Fig. 1, Fig. 2 are two kinds of prevailing mode of executions of the present utility model, when specifically implementing the utility model, shell 3 and core pipe 4 and body 1 all can be whole of single forming, but manufacture cost in order to save, reduce number of molds, upper-part all can be made into the unified interface end degree of lip-rounding and assembled.
Below in conjunction with accompanying drawing technical elements of the present utility model is further described.
Fig. 1 is the utility model duplex fitting structural representation;
Fig. 2 is the structural representation of the utility model tee union;
Fig. 3 is the structural representation of blooming and overlapping.
For solid attractive in appearance and antirust, shell 3 and inner core 4 can be made with stainless steel, and body 1, the cover 5 and threaded sleeve 6 of blooming all can made of plasticly be manufactured cost with reduction.The core pipe 4 that its structure is made with stainless steel places equally the endoporus of the shell made from stainless steel 3, the body made from plastic or other material 1 is filled between shell 3 and core pipe 4 and the two is fixed, if core pipe 4 is a splicing tubes, then on body 1 inwall corresponding to the assembly jointing of core pipe 4, enclosing the nontoxic sheath of one deck 2 makes provision against emergencies the generation seepage and pollutes water quality in the pipe, be provided with screw thread near the port on body 1 inner hole wall, the inner hole wall of inner end then is receives little truncated cone inwards; Cover 5 the endoporus of blooming is cylindrical and outer side surface is taper type, its size is corresponding with body 1 inner hole wall circular cone that front end is with tapering, in order better to seal leakage proof, a leakproof foundation ring 8 can be established in cover 5 the bottom of blooming, the interior ring place of leakproof foundation ring 8 also can establish the mouth of hook 9 that a circle protrudes inwards, in order to increase friction, also be provided with the boss 10 that a circle protrudes on the inner hole wall of the pipe 5 of blooming.Offer on the outer side surface of threaded sleeve 6 with body 1 inner hole wall near the port, the screw thread respective threads of opening.When connection is waited to take over body, wait to take over body 7 and insert in cover 5 endoporus of blooming, wait that the port of taking over body 7 withstands on the leakproof foundation ring 8 of cover 5 bottoms of blooming, the mouth of hook 9 at ring place hooks the inner hole wall of waiting to take over body 7 ports in the leakproof foundation ring 8; Be with bloom 5 wait that taking over body 7 inserts between core pipes 4 and the body 1, is placed in threaded sleeve 6 and waits to take over outside the body 7, and be tightened in the body 1; When threaded sleeve screws and is mobile inwards, push the cover 5 of blooming and move inwards, the outer side wall of the cover 5 of blooming is subjected to the inside grave of extruding of body 1 madial wall to wait for adapter 7, makes it tightly to be pressed on the outer side wall of core pipe 4, realizes fastening and leakage proof.
