Description
Technical field
The invention belongs to water heating pipe fittings technical field, particularly relate to a kind of pipe joint.
Background technique
Current water pipe system, generally adopts the materials such as PR, PPT to replace metal pipe element, and in pipe fitting is installed, often need to use pipe joint carrys out connecting pipeline, as straight-through, elbow, u shaped connector, threeway, four-way etc.Common pipe joint comprises a collection remittance portion, at least two external parts, and each external part is one-body molded with collection remittance portion, has some stiffening ribs on external part, and each external part also has a supporting retaining ring with it.During use, pipe joint is connected with pipeline, each external part inserts respectively in pipeline, and Fixing shrink ring is outside pipeline and be stuck in the stiffening rib place of external part, thus the combination that makes pipeline and external part close and firm more.Claimant studies discovery, and the fixed position of retaining ring has a great impact the combination tightness degree of pipeline.Because the stiffening rib of external part is the ring-type being arranged in parallel, between two adjacent stiffening ribs, be white space, when the coverage area of retaining ring only covers a stiffening rib, its fixed effect is unsatisfactory; When retaining ring can cover two stiffening ribs, while " riding " on two stiffening ribs, its fixed effect can be better; When retaining ring, can " ride " evenly on two stiffening ribs, when the medium line of the axial centerline of retaining ring and adjacent two stiffening ribs is overlapping, fixed effect is best.But how when retaining ring is installed, can the disposable optimum position that retaining ring is arranged on to external part, be that these those skilled in the art are difficult to the problem place effectively solving.
Summary of the invention
The object of this invention is to provide the more pipe joint of close and firm of a kind of connection, thereby effectively determine the best position of retaining ring.
Adopt following technological scheme: a kind of pipe joint for this reason, comprise a collection remittance portion, at least two external parts, each external part is one-body molded with collection remittance portion, on external part, there are some stiffening ribs, in the form of a ring and be arranged in parallel within on external part, each external part also has a supporting retaining ring with it to described stiffening rib; The external diameter of external part matches with the required pipeline internal diameter being connected, and the internal diameter of retaining ring matches with the required pipeline external diameter being connected; It is characterized in that: on the outer wall of collection remittance portion, be provided with some locating columns, described locating column has holding part and spacing section, holding part is vertically fixed on tube wall also one-body molded, and the head of spacing section and holding part fix and at right angles bending, and the afterbody of spacing section and retaining ring can contact; The horizontal width of described retaining ring is greater than the spacing between adjacent two stiffening ribs on described external part, and when retaining ring and spacing segment trailer contact, retaining ring covers on two stiffening ribs of external part.
Further, when retaining ring and spacing segment trailer contact, the medium line of the axial centerline of retaining ring and its two adjacent stiffening ribs that cover is overlapping.
When the present invention installs, first by Fixing shrink ring outside pipeline, then the external part of pipe joint is inserted in pipeline, now utilize the elasticity of material itself can complete connection, the tube wall of pipeline is between external part and locating column spacing section; Mobile retaining ring, makes its spacing segment trailer that contacts pipe joint locating column again, and now retaining ring " is ridden " evenly on two stiffening ribs, completes connection work.This mounting type, can easily and accurately retaining ring be arranged on to the optimum position of pipe joint external part, after retaining ring and spacing segment trailer contact, the pivotal axis of retaining ring is overlapping with the adjacent stiffening rib medium line that retaining ring covers to the midline, and retaining ring covers on the adjacent stiffening rib of external part evenly.

Embodiment
Referring to accompanying drawing.Embodiment 1 comprises pipe joint 1, pipeline 2 and retaining ring 3.Pipe joint 1 has collection remittance portion 12 and external part 11, and external part 11 is one-body molded with collection remittance portion 12, has two stiffening ribs 13 on external part 11, and described stiffening rib 13 in the form of a ring and be arranged in parallel within on external part 11; The external diameter of external part matches with the required pipeline internal diameter being connected, and the internal diameter of retaining ring matches with the required pipeline external diameter being connected; On described pipe joint, be also provided with locating column 4, locating column 4 has the holding part 41 of Vertical direction and spacing section 42 of substantially horizontal, and the holding part 41 that passes through of described locating column 4 is fixed in the collection remittance portion 12 of pipe joint 1; Described retaining ring 3 energy engage sleeves are on pipeline tubing 1, and retaining ring 3 thickness are slightly larger than the gap of spacing section 42 of locating column and pipeline 2.The horizontal width of described retaining ring 3 is greater than the spacing between adjacent two stiffening ribs on described external part, and when retaining ring 3 moves to spacing segment trailer and contacts position, the pivotal axis of retaining ring 3 is overlapping with the adjacent stiffening rib medium line that retaining ring 3 covers to the midline.Embodiment 1 is free flow coupling 1a, there are two external parts 11 with pipe interface, in the middle part of free flow coupling 1a collection remittance portion 12 both sides, be fixed with locating column 4, the locating column of every side shares a holding part 41, and extends upward positive stop end 42 along the axle of free flow coupling 1a.
