Abstract
The invention discloses a thread connection method and a structure for a pipeline. The structure is characterized in that a threaded joint is axially divided into more than two parts in the manner of split assembly, then more than two threaded joint assemblies are assembled and buckled on a pipeline to be connected, and are also connected with corresponding nuts. The invention can conveniently realize that plastic tubes can be movably and conveniently connected by threads, can realize that metal tubes can be movably connected by threads in special positions, and has the advantages of simple structure, convenience for installation and good popularization value.
Description
Technical field
The present invention relates to the pipeline connection technology field, relate to a kind of threaded connection method and structure of pipeline in particular.
Background technique
When plastic tube need be threaded and since injection moulding need inipple to be installed to plastic tube in advance to get on, also just can't flexibly connect by the nut corresponding with other; For 90 short degree bending metal tubes of an end; When bending fillet hour (the regular screw threads joint can't stride across bending part); Receive the needs of pier nose or welding, inipple also can't be installed on the metal tube in advance, also just can't connect by the nut corresponding with other.In view of plastic tube and particulate metal pipe can't use the problem that is threaded, those skilled in the art are necessary to develop and a kind ofly can guarantee that any pipeline can adopt thread connecting mode, guarantees the reliability that connects.
Summary of the invention
The object of the invention is exactly provide for the deficiency that solves existing technology a kind of not only simple in structure, easy for installation, but also can guarantee that any pipeline can adopt thread connecting mode, the threaded connection method of the pipeline of the reliability of guaranteeing to connect.
Another object of the present invention provides a kind ofly can guarantee that any pipeline can adopt thread connecting mode, the screw connection structure of the pipeline of the reliability of guaranteeing to connect.
The present invention adopts following technical solution to realize above-mentioned purpose: a kind of threaded connection method of pipeline; It is characterized in that; It is to adopt the mode of split assembling that inipple axially is cut into more than two parts along it; Then plural nipple assembly assembling is fastened on the pipeline that needs to connect, and connects with corresponding nut.
As further specifying of such scheme: the mode that said inipple preferably is divided into two; Two partial thread adapter assemblies snap together to guarantee it is a complete worm structure; And require on the partial thread buckling surface, to adopt over-surplus fit structure, be difficult for behind the fastening getting loose.
Said nipple assembly adopts the mode of molding and forming.
On the buckling surface of said nipple assembly, increase draw-in groove and fixture block, be difficult for getting loose with after guaranteeing to fasten.
A kind of screw connection structure of pipeline is characterized in that, it comprises the nipple assembly that can be assembled into a complete worm structure more than two.
Adopt manner to connect between the said nipple assembly more than two, be provided with the positioning means of forming by the draw-in groove and the fixture block of concavo-convex cooperation more than two groups at the buckling surface of adjacent two screwed assemblies.
Said complete worm structure preferably is made up of two partial thread assemblies, adopts over-surplus fit structure on the partial thread buckling surface, is difficult for behind the fastening getting loose.
The outside thread position arranged outside of said screwed assembly has flange.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
The present invention adopts the injection moulding respectively of regular screw threads joint separated into two parts; Be difficult for getting loose behind the fastening guaranteeing increasing draw-in groove and fixture block on the buckling surface of injection moulding; After the injection moulding two partial thread joints are fastened on the pipeline that needs to connect; And connect with corresponding nut, can realize very easily that the movable whorl of plastic tube connects, can realize also that at specific position the metal tube movable whorl connects.

Embodiment
The threaded connection method of a kind of pipeline of the present invention; It is to adopt the mode of split assembling that inipple axially is cut into more than two parts along it; Then plural nipple assembly assembling is fastened on the pipeline that needs to connect, and connects with corresponding nut.In the present embodiment, the mode that inipple preferably is divided into two, two partial thread adapter assemblies snap together to guarantee it is a complete worm structure, and require on the partial thread buckling surface, to adopt over-surplus fit structure, are difficult for behind the fastening getting loose.Nipple assembly can adopt the mode of molding and forming, on the buckling surface of said nipple assembly, increases draw-in groove and fixture block, is difficult for getting loose with after guaranteeing to fasten.
Like Fig. 1, shown in Figure 2; It below is the linkage structure that the screw method with said pipeline matches; It comprises the nipple assembly 1 that can be assembled into a complete worm structure more than two; Adopt manner to connect between the said nipple assembly 1 more than two, be provided with more than two groups the positioning means of forming by the draw-in groove 3 of concavo-convex cooperation and fixture block 4 at the buckling surface 2 of adjacent two screwed assemblies.Wherein, complete worm structure preferably is made up of two partial thread assemblies 1, adopts over-surplus fit structure on the partial thread buckling surface, is difficult for behind the fastening getting loose.External thread part 6 arranged outside at screwed assembly have flange 5.After the injection moulding two partial thread joints are fastened on the pipeline that need to connect, and connect with corresponding nut and to get final product.
Above-described only is preferred implementation of the present invention, should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, and these all belong to protection scope of the present invention.
