Abstract
The utility model discloses a pipe joint which belongs to the field of non-detachable pipe joints. The pipe joint comprises a joint body (1) and a slip joint (2), wherein the outer diameter of the combined section (3) of the joint body of the slip joint is matched with the inner diameter of an interface (4) of the joint body, and the combined section of the joint body is inserted in the interface; the outer diameter of the combined section of an outer connection pipe of the slip joint is smaller than the outer diameter of the interface. The use of the pipe joint is convenient, and the appearance is beautiful when the pipe joint is connected with a pipe. The pipe joint can be used in the fields of advertisement signboards, decoration, metal furniture, fitness equipment, tap water pipes, etc.
Description
The utility model relates to a kind of pipe joint, belongs to non-removable pipe joint field.
In the prior art, be connected the normal method that is threaded that adopts between pipe and the pipe joint, this connection must be attacked screw thread with the pipe end outer wall at the interface inwall of pipe joint and just can be connected.This is for stainless steel cladding steel pipe and pipe joint, and it is not very good adopting this method, because the skin of stainless steel cladding steel pipe is a stainless steel, internal layer is a carbon steel, as tapping, then certainly will destroy stainless steel lining, thereby cause the joint with the passing of time to be got rusty.Chinese patent application 92103042.8 discloses a kind of " rubber joint pipe attached method ", and it is that pipe is directly inserted in the pipe fitting, filling adhesive in the two gap.Though it can separate the problem of never destroying stainless steel lining, it is with in the pipe insertion tube connector interface, and outstanding one in the connection place, out-of-flatness is smooth, has influenced attractive in appearance.As pipe being enclosed within on the pipe joint interface, then can address this problem.But the prior art pipe joint is whole one-body molded, and pipe joint interface external diameter is fixed, as connects the pipe of same external diameter, different inner diameters, then must use the pipe joint of different model, has so both increased cost of production and time, causes complex manufacturingization again.
The purpose of this utility model is to provide a kind of and engages conveniently firmly, cost of production is low, make joint pipe joint more attractive in appearance.
Technical solution of the present utility model is:
A kind of pipe joint comprises fittings body and expansion joint, and the external diameter of the fittings body adapter section of expansion joint matches with the internal diameter of the interface of fittings body, and the fittings body adapter section inserts in the interface, and the external diameter of the externally connected pipe adapter section of expansion joint is less than the interface external diameter.Scribble adhesive in the joint gap between described fittings body adapter section and interface.
The external diameter of externally connected pipe adapter section matches with the internal diameter of externally connected pipe, and the external diameter of externally connected pipe equals fittings body interface external diameter.When using the externally connected pipe that external diameter is identical with fittings body interface external diameter, pipe thickness is different, the external diameter that need only change the externally connected pipe adapter section of expansion joint gets final product, promptly need only use different expansion joints, and needn't change whole pipe joint, make easy to use, cost of production reduce, fittings body can be two logical, threeway, four-way and other structure.In addition, when externally connected pipe is stretched owing to temperature variation,, two places are arranged for glueing joint because externally connected pipe and fittings body are to be coupled together by expansion joint, because adhesive is heated on the contrary within the specific limits can be because of expansion increases elasticity, thereby can clear up the flexible of externally connected pipe.
The utility model has following advantage than prior art: (1) cost of production is low, and be connected the joint, back with pipe smooth, attractive in appearance; When (2) being connected, need only using different expansion joints, and needn't change fittings body, make to engage conveniently with the pipe of same outer diameter as, different inner diameters; (3) can clear up pipe well because of stretching that temperature variation causes, thereby engage firmly.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the sectional view of the utility model pipe joint.
Fig. 2 is the sectional view of externally connected pipe tube wall employed expansion joint when thicker.
Fig. 3 is the sectional view of externally connected pipe tube wall employed expansion joint when thin.
Fig. 4 is the cross-sectional schematic of the utility model pipe joint when being connected with pipe.
A kind of pipe joint comprises fittings body 1 and expansion joint 2, and fittings body 1 and expansion joint 2 are made by composite stainless steel.Fittings body 1 is the tee union body, and the internal diameter of the interface 4 of fittings body is 60mm, and external diameter is 70mm; The external diameter of the fittings body adapter section 3 of expansion joint matches with the internal diameter of the interface 4 of fittings body, be 60mm, fittings body adapter section 3 inserts in the interface 4, scribble AV glue in the joint gap between fittings body adapter section 3 and interface 4, the external diameter of the externally connected pipe adapter section 5 of expansion joint is less than the external diameter of interface 4, at this is 64mm, it is that 70mm, internal diameter are that the externally connected pipe 6 of 64mm is connected with an external diameter, and coating AV glue in the joint gap between externally connected pipe adapter section and externally connected pipe can couple together pipe joint and pipe well.Outward appearance is very smooth, attractive in appearance in the joint of pipe joint and pipe.
Claims (2)
1. pipe joint, comprise fittings body, it is characterized in that: this pipe joint also comprises expansion joint (2), the external diameter of the fittings body adapter section (3) of expansion joint matches with the internal diameter of the interface (4) of fittings body (1), fittings body adapter section (3) inserts in the interface (4), and the external diameter of the externally connected pipe adapter section (5) of expansion joint is less than the external diameter of interface (4).
2. pipe joint according to claim 1 is characterized in that: scribble adhesive in the joint gap between described fittings body adapter section (3) and interface (4).
