Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of structure of heat molten type pipe fitting joint.
Background technique
In prior art, conventional water pipe and pipe joint are metalwork mostly, because metallic water pipe can not be crooked, so need field fabrication while installing, joint with water pipe with being threaded, not only cost is high but also operation quite bothers, and the easy burn into of tube wall of metallic water pipe is short working life, also easily produces and leaks.In recent years, aluminium-plastic composite pipe owing to thering is in flexible indeformable, the level and smooth non-scaling non-corrosive of pipe inner and outer surface of not rebounding, pipe nontoxic non-leakage, the body flame-retardant and anti-static of plastic, high-temperature-resistant high-pressure-resistant is corrosion-resistant, appearance neat appearance is easy for installation, save labor the advantages such as province's expense and promote the use of gradually, but, aluminium-plastic composite pipe need to be used metal joint equally, and joint adopts crimping to be connected with water pipe, also easily produces and leaks.
For this situation, people have recognized this deficiency, and carry out improvement, a kind of two surface heating fusion plug-in joint [application number: 200520101882.7 openly proposing as Chinese patent literature data; Notice of authorization number: CN2797837Y], at least one end of this joint has the birdsmouth between inside and outside ring wall, and internal ring wall inner side is equipped with lining, and its birdsmouth also includes socket joint compensating groove.
But when the aperture of working as used composite pipe is greater than birdsmouth, composite pipe need to be connected with joint by the mode compressing, and conventionally adopt nut that composite pipe and joint one end are compressed to connection, but owing to there is no the structure of set screw nut on this joint, make connecting water pipe become loaded down with trivial details.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed joint a kind of and that water pipe is easy to connect.
The purpose of this utility model can realize by following technical proposal: a kind of joint, comprise tubular body, described body one end has ringwise connecting groove and described connecting groove and described body and coaxially arranges, it is characterized in that, the outer side wall of the other end of described body has annular convex and described annular convex and described body and coaxially arranges.
During this joint the other end connecting water pipe, need attaching nut and water pipe and joint use by compressing; During use, nut is suspended on annular convex and the nut the other end is connected with water pipe thread water pipe and joint are connected; By annular convex is set, facilitate nut to be connected on joint, further make water pipe convenient with being connected of joint.
In above-mentioned a kind of joint, the lower end surface of described annular convex is provided with annular groove, and described annular groove and described annular convex coaxially arrange.Adopt such design, improve the sealing contacting of water pipe and the body the other end.
In above-mentioned a kind of joint, the quantity of described annular groove is 1 to 4 and is coaxial setting.
In above-mentioned a kind of joint, described connecting groove inwall is provided with the air vent that is strip, and described air vent is along the axial setting of described body.When this joint and composite pipe welding, the air in connecting groove is discharged by air vent, avoids at welding position, forming bubble, guarantees welding effect.
In above-mentioned a kind of joint, the sidewall of described body is equipped with exhaust port and described exhaust port and is connected with the cavity of described connecting groove.When this joint and composite pipe welding, the air in connecting groove is discharged by exhaust port, avoids at welding position, forming bubble, guarantees welding effect.
In above-mentioned a kind of joint, the inside cavity on described body with one end of connecting groove is provided with lining, and described lining is connected with described body close-fitting.In the time of in composite pipe is inserted into connecting groove, lining has supporting role to inner body wall and composite pipe, thereby composite pipe and joint are fused and linked together well.
In above-mentioned a kind of joint, in the cavity of described body, there is convex shoulder, the interior edge face of described lining is resisted against on the end face of described convex shoulder.When with composite pipe welding, convex shoulder positions lining, guarantees can be positioned at suitable position with composite pipe welding back bush.
In above-mentioned a kind of joint, the other end of described body has the annular boss of protrusion, and described annular boss and described body coaxially arrange.During use, annular boss the inner is inserted in water pipe, prevents from occurring in use leaking.
In above-mentioned a kind of joint, described body adopts PERT material to make.Body is made by PERT material, make body have quality light, be easy to transportation, install, have the advantages such as good pliability, good environmental suitability, heat-resistant pressure-resistant are good.
Compared with prior art, this water pipe has the following advantages:
1, the outer side wall by the body the other end has the annular convex with the coaxial setting of body, facilitates the installation of water pipe.
2, the sidewall by body is equipped with exhaust port and exhaust port is connected with the cavity of connecting groove, by the Bas Discharged in connecting groove to guarantee welding effect.
3, by annular boss, be inserted in water pipe, prevent that leaking appears in the joint of joint and water pipe in use.
