Background technique
Conduit fast connection structure is a kind of joint that does not need instrument just can realize pipeline connection or disconnection.In the prior art, conduit fast connection structure generally comprises fittings body and nut, and the conduit fast connection structure of this structure easily makes shedding, and overall construction intensity is not high.
The problem that exists in order to solve prior art, people have carried out long-term exploration, have proposed various solutions.For example, Chinese patent literature discloses a kind of conduit fast connection structure [application number: 200820060571.4], be included in the outer side surface moulding outside thread of a tubular body, one collar inner side surface moulding internal thread, the collar when making the relative body rotation of the collar, can make the axial displacement of cover hoop body with the external thread spiro fastening of internal thread and body, in the time of in water pipe is inserted in body, can be got loose to the location of water pipe by the axial displacement of the collar.
Such scheme has improved prior art to a certain extent, but at least also has following problem: complex structure, install loaded down with trivial detailsly, and still exist in addition structural strength not high, the fixing problem such as not firm, after long-term the use, the problem such as will occur coming off and leak.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of reasonable in design, simple in structure, and simple installation is quick, and structural strength is high, and is fixed, the conduit fast connection structure of long service life.
For achieving the above object, the utility model has adopted following technical proposal: be arranged between the first adapter and the second adapter, described second takes over an end has the reducing intubate, this linkage structure comprises that being placed in first takes over peripheral banding cover, outer race at the banding cover has locking cap, described locking cap can be taken over by worm structure and second and link to each other, it is characterized in that, be provided with between described locking cap and the banding cover to take over when locking cap and second and can make after being connected the banding cover be held in first to take over upper and driven propelling movement structure on the reducing intubate that the first adapter is enclosed within the second adapter by the banding cover.
In above-mentioned conduit fast connection structure, described propelling movement structure comprises the inner conical surface of being located at the locking cap inwall and the male cone (strobilus masculinus) of being located at banding cover periphery, and described inner conical surface and male cone (strobilus masculinus) lean.
Owing to being provided with the propelling movement structure, it is by pushing structure that it is firmly fixing that the first pipeline passes locking cap, and Simple fast is installed, and improved simultaneously whole structural strength, fixed, prolonged working life.
In above-mentioned conduit fast connection structure, the cross section of described banding cover is the C type.More firm after the installation.
In above-mentioned conduit fast connection structure, described the first adapter is made by nonmetallic material, and described the second adapter is made by metallic material.
In above-mentioned conduit fast connection structure, described banding cover inwall is provided with snap ring in some back-offs.
In above-mentioned conduit fast connection structure, described reducing intubate is arranged with the outer snap ring of some back-offs outward.
Owing to being provided with snap ring and the outer snap ring of back-off in the back-off, install fixedly, further improved overall construction intensity.
Compared with prior art, the advantage of this conduit fast connection structure is: 1, design is more reasonable.2, owing to being provided with the propelling movement structure, it is by pushing structure that it is firmly fixing that the first pipeline passes locking cap, and Simple fast is installed, and improved simultaneously whole structural strength, fixed, prolonged working life.3, owing to being provided with snap ring and the outer snap ring of back-off in the back-off, install fixedly, further improved overall construction intensity.
Description of drawings
Fig. 1 is the broken section structural representation that the utility model provides.
Fig. 2 is the banding nested structure schematic diagram that the utility model provides.
Among the figure, first takes over snap ring 32 in the 1, second adapter 2, reducing intubate 21, banding cover 3, locking cap 4, inner conical surface 41, male cone (strobilus masculinus) 31, the back-off, the outer snap ring 21a of back-off.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Such as Fig. 1, shown in 2, this conduit fast connection structure, being arranged on first takes between the 1 and second adapter 2, take over 2 one ends second and have reducing intubate 21, this linkage structure comprises that being placed in the first banding of taking over 1 periphery overlaps 3, outer race at banding cover 3 has locking cap 4, described locking cap 4 can be taken over 2 by worm structure and second and link to each other, is provided with to take over 2 when locking cap 4 and second and can make after being connected banding cover 3 be held in first to take on 1 and overlapped 3 drives the first adapter 1 by banding and be enclosed within propelling movement structure on the reducing intubate 21 of the second adapter 2 between locking cap 4 and banding cover 3.Further, first takes over 1 is made by nonmetallic material, and second takes over 2 is made by metallic material.
Concrete, above-mentioned propelling movement structure comprises the inner conical surface 41 of being located at locking cap 4 inwalls and is located at the male cone (strobilus masculinus) 31 that banding overlaps 3 peripheries, and described inner conical surface 41 leans with male cone (strobilus masculinus) 31.
