Abstract
The utility model discloses a hard pipe clamping and sleeving joint. The joint comprises a connecting pipe sleeve and a pipe cap, wherein one end of the connecting pipe sleeve is provided with an internal thread matched with an external thread of a pipeline, and the other end is provided with an external thread; the pipe cap is matched with the external thread of the connecting pipe sleeve; one end of the pipe cap is provided with a convergent end surface; a fixed pipe ring is arranged inside the pipe cap; and a rubber sealing ring in interference fit with the connecting pipe sleeve is arranged inside the connecting pipe sleeve and pressed against the fixed pipe ring. By the aid of the joint, the problem about butt joint of a threaded pipeline and a non-threaded pipeline is solved, and the joint is convenient to install, good in sealing performance and capable of being widely used in the field of pipeline joints.
Description
Technical field
The utility model relates to fluid line field, especially relates to a kind of hard tube ferrule fitting.
Background technique
Pipe joint is conventional link in fluid line transportation.For meeting flow of fluid requirement, make pipe joint must possess good sealing, generally adopt at present marine glue fabric envelope to seal on threaded pipe, and mostly be disposable linkage structure, can not repeated disassembled and assembled use.And the man's activity of mackintosh form is large, and misoperation is easily leaked.The pipeline that needs the pipe joint of frequent dismounting for some, the pipe joint structure of this kind of disposable connection often causes the waste on cost.Meanwhile, some threaded tube is docked with non-threaded pipeline, and general pipe joint is difficult to meet.
Therefore need to design a kind of can being dismounted for multiple times and guarantee the plug of good sealing property as Chinese Patent Application No. 97239914.3 discloses a kind of pipe joint, more specifically to say a kind of joint for plastic tube that carries out sealed attachment by rotating nut.Mainly solving prior art use to install inconvenience, is prone to quality problems and inconvenience dismounting and the shortcoming such as can not reuses.This joint for plastic tube is provided with at least two joints on a fittings body, on each joint, with screw thread, one gland nut is installed, an elastic ring of installing in this gland nut, elastic ring is provided with distortion groove, between the rear end of described elastic ring and the end face of described joint, is provided with seal ring.
Model utility content
The purpose of this utility model is to provide a kind of hard tube ferrule fitting, solves existing pipe joint and can not meet the problem that threaded pipe docks with non-threaded pipe.
The utility model solves the technological scheme that its technical problem adopts: a kind of hard tube ferrule fitting, comprise connection pipe box, and the one end that connects pipe box is provided with the internal thread coordinating with pipeline outside thread, and the other end is provided with outside thread; Also be provided with and the pipe cap that is connected the cooperation of pipe box outside thread, pipe cap one end is provided with closing in end face; In pipe cap, be provided with fixedly pipeloop, connect in pipe box and be provided with and the rubber seal that is connected pipe box interference fit, rubber seal is pressed in fixedly on pipeloop.
For convenience of rubber seal, location is installed, is provided with a ledge structure on described rubber seal outer side surface, the step surface of ledge structure is pressed on the end face that connects pipe box; On the end face that described fixedly pipe box coordinates with rubber seal, be provided with convex shoulder, on described rubber seal end face, be provided with the concave surface coordinating with convex shoulder; The inwall interference fit of described rubber seal and pipe cap.
For guaranteeing that fixedly pipeloop coordinates with pipe cap closely, described fixedly pipeloop is cone structure, and fixedly on pipeloop, has one group of distortion breach of stepping down.
For convenience of the installation of pipeline, one end and externally threaded one end of described connection pipe box internal thread are provided with tapering transition section, by large through the aperture of female end, by little through the aperture of male end.The internal diameter of described connection pipe box male end is greater than tapering transition section by through the internal diameter of male end, and male end and tapering transition be intersegmental transition shoulder.
The beneficial effects of the utility model: the one end by hard tube ferrule fitting arranges internal thread and coordinates with threaded pipe, the other end arranges the sealing configuration of outside thread and rubber seal, install and the not threaded pipeline of sealing, realize threaded tube and dock with the quick mounting of non-threaded pipeline.And this hard tube ferrule fitting good airproof performance, can repeated disassembled and assembled.Breach on described fixedly pipeloop guarantees to make being fixed pipeloop, can have certain distortion, and fixedly pipeloop is coordinated with pipe cap closely, guarantees sealing.Described rubber seal be connected pipe box, the fixing cooperating structure good airproof performance of pipeloop, and easy for installation.
Below with reference to drawings and Examples, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Embodiment
Embodiment, as shown in Figure 1, a kind of hard tube ferrule fitting, comprises and connects pipe box 1, the one end that connects pipe box 1 is provided with the internal thread coordinating with pipeline outside thread, the other end is provided with outside thread; Also be provided with and the pipe cap 4 that is connected pipe box 1 outside thread cooperation, pipe cap 4 one end are provided with closing in end face 7; In pipe cap 4, be provided with fixedly pipeloop 3, connect in pipe box 1 and be provided with and the rubber seal 2 that is connected pipe box 1 interference fit, rubber seal 2 is pressed in fixedly on pipeloop 3.
On described rubber seal 2 outer side surfaces, be provided with a ledge structure 5, the step surface of ledge structure 5 is pressed on the end face that connects pipe box 1; The inwall interference fit of described rubber seal 2 and pipe cap 4.When guaranteeing sealing, facilitate rubber seal assembling.
Described fixedly pipeloop 3 is cone structure, and fixedly on pipeloop 3, has one group of distortion breach 6 of stepping down.When connecting tube, by screwing pipe cap 4, make pipe cap 4, pipeline pipeloop 3 and rubber seal 2 being pressed on adapter sleeve 1 tightly, meanwhile, fixedly pipeloop 3 is out of shape under the effect of spinning force, makes fixedly pipeloop 3 tightly embrace pipe box, guarantees sealing.
One end and externally threaded one end of described connection pipe box 1 internal thread are provided with tapering transition section 8, by large through the aperture of female end, by little through the aperture of male end.The internal diameter of described connection pipe box 1 male end is greater than tapering transition section 8 by the internal diameter through male end, and 8 of male end and tapering transition sections have transition shoulder 9.
