Abstract
Disclosed is an externally-locked type quick metal connector for plastic pipelines. The externally-locked type quick metal connector is a cylindrical metal pipe fitting and comprises a thick head section and a thin head section, the thick head section is longer than the thin head section, the thick head section is larger than the thin head section in the inner diameter, and wall thickness of the thick head section is equal to that of the thin head section. An annular groove or an annual boss is formed in the outer diameter of the thin head section. At least two lines of threaded teeth are arranged in a position, where the thick head section is connected with the thin head section, of the inner wall of the thick head section. During mounting of the externally-locked type quick metal connector made of a metal material, the protruding threaded teeth are pierced into the outer wall of a plastic pipe to be tightly locked under the action of external force, and then a national standard groove type clamp or a clamping ring type clamp is used to be connected in a clamped manner with other pipelines or standard pipe fittings. By the externally-locked type quick metal connector, the easily-appearing situations of water leakage, air leakage, falling off and breakage of the pipelines in an existing connecting mode are effectively avoided; the externally-locked type quick metal connector is simple in connecting process, convenient and rapid to mount and demount and low in cost, and sealing effect is obviously superior to that of an existing structure.
Description
Technical field
The utility model belongs to pipeline connection area, relates to a kind of Placement of plastic pipe, especially relates to a kind of external locking type plastic pipe metal fast connector.
Background technique
At present, in our daily life, known plastic pipe Placement roughly has: a kind of is the hot fusion method for linking of polyethylene, three type polypropylene pipes, another kind is bonding peaceful flange connection method at two ends, PVC＝polyvinyl chloride road, and also having a kind of is to insert connection method after solvent-borne type joint socket or elastic seal ring type joint socket are expanded in the heating of polyvinyl chloride pipeline.Said method is all difficult to accomplish to install fast and efficiently, dismantle and keep in repair.Especially can not large batch ofly be applied under mine and coal mine.Because the operating mode under mine or coal mine is severe, pipeline cannot effectively be fixed, and because the working pressure of pipeline is very unstable, the reason such as humid environment, narrow space, after causing existing method to connect easily there is the gas leak phenomenon that comes off, ruptures, leaks in pipe coupling, increase inconvenience to mine and colliery downhole production, even have great potential safety hazard.
Model utility content
The external locking type plastic pipe metal fast connector that the purpose of this utility model is to provide a kind of compact structure, good airproof performance, can conveniently installs, dismantle, keep in repair.Effectively overcome existing Placement shedding, gas leak phenomenon ruptures, leaks.
The utility model adopts following technological scheme to achieve the above object: external locking type plastic pipe metal fast connector is cylindrical metal pipe fitting, comprising: thick head section and thin head section; The length of thick head section is greater than the length of thin head section, and the internal diameter of thick head section is greater than the internal diameter of thin head section, and the wall thickness of thick head section equals the wall thickness of thin head section.
On described thin head section external diameter, be provided with annular groove.
On described thin head section external diameter, be provided with annular boss.
On the inwall of described thick head section and the thick head in thin head section joint section, be provided with the ring shaped thread tooth that is no less than twice.
On the inwall of described thick head section and the thick head in thin head section joint section, be provided with the wedge-like thread that is no less than twice.
Owing to having adopted technique scheme, the utlity model has following beneficial effect: the utility model is made by metallic material, by at the thin head section outer installment annular groove of metal connecting head or annular boss, be convenient to be connected with other standard pipe fitting with groove type clip or the clasp type clip of GB, the thick head section internal diameter of metal connecting head is a bit larger tham plastic tube external diameter, being convenient to plastic tube inserts in metal connecting head, in thick head section inwall, be provided with ring-type or wedge-like thread, after protrusion thread being thrust to plastic tube outer wall under mechanical external force effect, lock, then use GB groove type clip or clasp type clip to be connected with other pipeline or standard pipe fitting.The utility model has effectively stopped that the pipe leakage that existing Placement is prone to leaks gas, comes off, phenomenon of rupture, has that the technique of connection is simple, easy installation and removal is quick, and cost is lower, and sealing effect is obviously better than existing structure.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of the utility model external locking type plastic pipe metal fast connector;
Fig. 2 is another embodiment's of metal fast connector of the utility model external locking type plastic pipe cross-sectional view;
Fig. 3 is that the metal fast connector of the utility model external locking type plastic pipe docks cross-sectional view with plastic pipe.
Embodiment
Below in conjunction with embodiment, the utility model is further described.External locking type plastic pipe metal fast connector as shown in Fig. 1～3 is cylindrical metal pipe fitting, can use copper material, aluminum alloy, cast iron, steel or stainless steel and other metal materials to make.Comprise: thick head section 1 and thin head section 2; The length L 1 of thick head section 1 is greater than the length L 2 of thin head section 2, and the internal diameter ф 1 of thick head section 1 is greater than the internal diameter ф 2 of thin head section 2, and the wall thickness H 1 of thick head section 1 equals in the wall thickness H 2 of thin head section 2.In first embodiment, on thin section 2 external diameters, be provided with annular groove 3, on the inwall of thick section 1 of thick head section 1 and thin head section 2 joints, be provided with the ring shaped thread tooth 5 that is no less than twice; In second embodiment, on thin section 2 external diameters, be provided with annular boss 4, on the inwall of thick section 1 of thick head section 1 and thin head section 2 joints, be provided with the wedge-like thread 6 that is no less than twice.
In above-mentioned two embodiments, the difference of connecting head is annular groove 3 and the annular boss 4 that thin head section 2 external diameters arrange, the ring shaped thread tooth 5 or the wedge-like thread 6 that on the inwall of thick head section 1, arrange.The internal diameter of thick head section 1 is a bit larger tham plastic pipe 7 external diameters, and object is that plastic pipe 7 can insert in the thick head section 1 of metal connecting head comparatively smoothly, locks after being convenient under external force the thread of protrusion to be thrust the outer wall of plastic pipe 7.Groove type clip or clasp type clip by GB are in clamping connection with other standard pipe fitting; In practice, the shape of thread is not limited to above-mentioned two kinds, and the change of other thread tooth consistent with its thinking is all within rights protection of the present utility model.
The utility model has effectively stopped that the pipe leakage that existing Placement is prone to leaks gas, comes off, phenomenon of rupture, has that the technique of connection is simple, easy installation and removal is quick, and cost is lower, and sealing effect is obviously better than existing structure.
