A pipe fitting is made of plastics and comprises an elbow joint and a fastening nut, wherein the elbow joint is in screwed combination with the fastening nut. The quick-connection plastic elbow joint is characterized in that the elbow joint includes a fastening segment and connecting segments, the connecting segments are arranged at two ends of the fastening segment, sealing threads are arranged on the outer sides of the connecting segments, fastening thread is arranged on the outer side of the fastening segment, the fastening nut is divided into an upper end opening and a lower end opening, the inner diameter of the upper end opening matches with the outer diameter of the fastening segment of the elbow joint, and the inner diameter of the lower end opening matches with the outer diameter of each connecting segment of the elbow joint. The quick-connection plastic elbow joint has the advantages that the elbow joint has simple structure, fast installation and fine sealing performance, can realize connection of two pipe sections quickly, greatly increases installation efficiency, simultaneously reduces waste of materials, decreases professional degree of operations and brings more convenience for users to install by themselves.
Description
Technical field
The utility model relates to pipe coupling, specifically is a kind of quick-acting type plastic bend tube joint.
Background technique
The connecting mode of plastic tube straight line pipeline known today mainly contains two kinds, a kind of is to adopt the enlarging technology at an end of plastic tube, pipe internal diameter local expansion in the length of regulation, be called bellmouth, then the non-female end of the tubing that links is inserted in the bellmouth, elastomer seal is housed or uses Bond at its connecting section, thereby realize being tightly connected between tubing.Also having a kind of mode is to adopt the hot melt butt welding to connect.But adopt the bellmouth connecting mode, sealability is bad, and manufacturing efficiency is low, can't utilize for the residue tubing that blocks when pipeline is installed especially again, and is bigger for the tubing waste, improves pipeline installing engineering cost.Adopt the mode manufacturing efficiency of hot melt butt welding low, need power connection, have relatively high expectations for installation conditions in the pipeline erecting bed.China's utility model patent numbers 200820068887.8, name is called " pipeline rapid pipe joint " and discloses a kind of left and right fittings body and be contained in the overcoat, binding site at left fittings body, right connector body and overcoat has a steel ball, between left side fittings body and the overcoat spring is arranged, outer cover pressing spring closes left fittings body fast and is connected or separates with the right connector body.Be not difficult to find out that the fast interface of this pipeline is to connect and separate by outer pressing spring, structure is too complicated, and has very big unstability after connection, is not suitable for promoting.
The model utility content
It is a kind of easy for installation that technical problem to be solved in the utility model is to provide, and makes simple quick-acting type plastic bend tube joint.
Technical problem to be solved in the utility model realizes by the following technical solutions,
A kind of quick-acting type plastic bend tube joint, tube material is made of plastics, comprise curved pass joint and fastening nut, bend between pass joint and the fastening nut by the spiral combination, it is characterized in that: described curved pass joint is divided into fastening section and linkage section, linkage section is arranged on fastening section two ends, outside described linkage section, sealing thread is set, fastening section is provided with binding thread outward, described fastening nut also is divided into upper end-hole and lower end mouth, the external diameter that described upper end-hole internal diameter and described curved pass joint are fastening section matches, and lower end mouth internal diameter and described curved pass joint linkage section external diameter match.
Described fastening section external diameter forms a boss greater than the external diameter of linkage section in the described fastening section linkage section junction with two ends.
The internal diameter of described upper end-hole forms a concave station greater than the internal diameter of lower end mouth in the junction of described upper end-hole internal diameter and lower end mouth internal diameter.
In the described sealing thread sealing gasket is set, is used to strengthen the tightness when contacting with internal diameter of the pipeline.
The utility model in use, the port of pipeline is enclosed within on the curved pass joint linkage section, the external diameter of the internal diameter of pipeline and curved pass joint linkage section is combined closely, after clamping bolt passes pipeline, is connected by the binding thread spiral of internal thread, with pipeline, curvedly connect mouth and clamping bolt combines closely with the curved adapter section of threading a pipe.
The beneficial effects of the utility model be simple in structure, install conveniently, can realize the connection in 2-section pipe road fast, and have good sealing property.When improving installation efficiency greatly, reduced the waste of material, reduced the degree of specialization of operation, be convenient to common user and install voluntarily.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of quick-acting type plastic bend tube joint, tube material is made of plastics, constitute by curved pass joint 1 and fastening nut 2, bend between pass joint 1 and the fastening nut 2 by the spiral combination, wherein curved pass joint 1 is divided into fastening section 11 and linkage section 12, linkage section 12 is arranged on fastening section 11 two ends, the linkage section 12 outer sealing threads 13 that are provided with, place sealing gasket 131 in the sealing thread 13, be used to strengthen the tightness when contacting, the fastening section 11 outer binding thread 14 that is provided with internal diameter of the pipeline, fastening like this section 11 external diameter is greater than the external diameter of linkage section 12, forms a boss 15 in linkage section 12 junctions at fastening section 11 and two ends.Wherein fastening nut 2 also is divided into upper end-hole 21 and lower end mouth 22, and the external diameter that upper end-hole 21 internal diameters and curved pass joint are fastening section 11 matches, and lower end mouth 22 internal diameters and curved pass joint linkage section 12 external diameters match.The internal diameter of upper end-hole 21 forms a concave station 23 greater than the internal diameter of lower end mouth 22 in the junction of upper end-hole 21 internal diameters and lower end mouth 22 internal diameters like this.
When reality connects, earlier pipeline 3 is passed fastening nut 2, interface end with institute adapter road 3 is enclosed within outside the sealing thread 13 then, combine with the linkage section 12 of curved pass joint 1, the edge of pipeline 3 is up to leaning after on the boss 15 of linkage section 12 and fastening section 11 combination, the upper end-hole 21 of fastening nut 2 and fastening section 11 of curved pass joint 1 are contacted, constantly rotate fastening nut 2, till when the concave station 23 in fastening nut 2 internal diameters and the boss 15 of curved pass joint 1 contact, institute adapter road 3 is linked to each other with linkage section 11 sealings of curved pass joint 1, equally, the other end of curved pass joint 1 also by fixedly connected other pipeline 3 of the method.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
