Abstract
The utility model provides a self-lock pipe connecting piece, composed of a housing of the pipe connecting piece, a pipeline, a locking spring, a rubber sealing-ring and a locking nut. With the rubber sealing-ring, the locking spring and the locking nut, the pipeline is fixed inside the housing of the pipe connecting piece. The rubber sealing-ring, the locking spring and the locking nut are arranged between the housing of the pipe connecting piece and the pipeline. With the advantages of simple structure, easy manufacturing, flexible disassembly, convenient operation, etc., the self-lock pipe connecting piece can be widely used in fast assembling construction of water pipelines, gas pipelines and heating pipelines of industrial facilities, agricultural facilities, mining facilities and civil facilities.
Description
The utility model relates to a kind of assembling pipe joint, specifically a kind of self-locking pipe connector.
The conveying of various liquid, gas be unable to do without pipeline, and as pipeline, gas pipe, heating pipe or the like from the beginning, pipeline has the branch of stereoplasm tube and soft pipe again, and stereoplasm tube has various metal tubes, plastic conduit, and flexible pipe then is various plastic flexible pipes.No matter be stereoplasm tube or soft pipe, being connected of pipeline and pipeline in use all unavoidably arranged, the connection ratio between the flexible pipe is easier to, and two sections flexible pipes can be coupled together with one section hard tube.The connection of hard tube is then more bothersome, the mode that connects stereoplasm tube with prior art is mainly welded two kinds with threaded pipe joint connection or with electrogas welding, the stereoplasm tube of medium and small straight warp generally is to connect with threaded pipe joint, the steel pipe of big straight warp or the connection of the copper pipe of ultra-fine diameter generally are to connect with the mode of welding, and then are to connect with electric welding or gas welding as bigbore gas pipe line, small-bore refrigerator radiator pipeline.But in daily life and industrial production, use maximum stereoplasm tubes to be mostly steel pipe, when connecting the steel pipe of medium and small straight warp with screwed pipe joint, at first be on connected steel pipe tube head, to put silk, just can be screwed on the pipe joint then, though the pipe joint that the connection steel pipe is used all is a standard piece, just available in the shop, but on the steel pipe tube head, mantle fiber not a nothing the matter just, instruments such as pipe tong and pipe thread chaser must be arranged, pipeline spread is the most time-consuming in pipeline construction, is exactly the mantle fiber of pipeline.With regard to by enterprises such as chemical industry, metallurgy, mines, the conveying of various liquid, gas medium mainly relies on the pipeline of various materials, and mostly employed pipeline is to fixedly connected with pipe connector by screw thread, these threaded pipelines and pipe connector are installed and used at production line, not only increased cost of production, and time-consuming, manufacturing efficiency is low, the requirement that the incompatibility modern industry is produced.The pipe connector that does not also have at present pipeline just can couple together pipeline and pipeline without mantle fiber.
The purpose of this utility model provides the self-locking pipe connector that a kind of pipe end only uses pipe connector just can couple together various hard pipelines without mantle fiber.Below with all kinds of hard tubing general designation pipelines.
The purpose of this utility model is by realizing with the lower direction formula, the interior circle of the pipe connector end that common connecting tube is used is processed into bell mouth shape, processing screw thread on the bell-mouthed inwall, the end that the threaded lock nut of middle perforate cylindrical is screwed in pipe connector is fixed on rubber seal and garter spring in the horn mouth.During use with the end in the middle of the pipeline of mantle fiber does not pass the locking nut of perforate inject among the pipe connector, then locking nut is tightened, locking nut just with garter spring, rubber-plastic sealing ring and not the pipeline of mantle fiber be fixed in the lump among the pipe connector.Garter spring in the pipe connector and the linear deformation under the compressing of lock nut of rubber-plastic sealing ring are connected and fixed pipe connector and pipeline and sealed.
Accompanying drawing is the linkage structure schematic representation between threeway self-locking pipe connector and the pipeline.
Explain below with reference to Figure of description self-locking pipe connecting piece of the present utility model being done.
Self-locking pipe connecting piece of the present utility model, its structure be by pipe connecting piece shell 5, pipeline 1, Locking spring 3, rubber seal 4 and locking nut 2 consist of, rubber seal 4, locking bullet Spring 3 and locking nut 2 are fixed on pipeline 1 among the pipe connecting piece shell 5, rubber seal 4, Locking spring 3 and locking nut 2 are between pipe connecting piece shell 5 and pipeline 1.
The end endoporus of pipe connector shell is a bell mouth shape, is processed with screw thread on the circle in bell-mouthed, and locking nut 2 is fixed on locking spring 3 and rubber seal 4 among the loudspeaker.
Embodiment:
The processing and fabricating of self-locking pipe connector of the present utility model is very simple and convenient, upward screw thread of horn mouth and processing will be processed into shown in the by specification accompanying drawing in the circle in the end of pipe connector, the middle perforate cylindrical threaded lock nut of getting on the bus is screwed in the end of pipe connector shell, locking spring, rubber-plastic sealing ring is fixed among the horn mouth of pipe connector end.Needing only during use pierces into not threaded pipeline in the pipe connector shell from the intermediate hole of nut, then with locking nut screwing, just pipeline and pipe connector can be coupled together, be clipped in the vertical distortion that is squeezed of locking spring between pipe connector shell and the pipeline and rubber or plastic seal ring and pipe connector shell and pipeline are fixed together and are sealed.Pipe connector shell described in the above-mentioned article is meant that all kinds of straight-through tube fittings, three-way pipe fitting, four-way pipe fitting and elbow, reducer pipe fitting and other play all kinds of pipe connectors of interconnect function.Pipeline is meant the various hard tubing that are used to carry liquid, gas.
Self-locking pipe connector of the present utility model generally only is used for the quick connection of civilian electromechanical equipment or hot-water heating facility, do not have family's hot-water heating installation of steel pipe machining tool, can be used for the ventilating drainage operation of the frequent farmland discharging-irrigating of piping erection dismounting, building site, mine etc. yet.
Self-locking pipe connecting piece of the present utility model be compared with existing technology have simple in structure, be easy to add The worker, the dismounting flexible, easy to use, etc. characteristics, can be widely used in industry, agricultural, mine, the people With the Fast Installation construction in the water of facility, gas, heating coil road, thereby, have well and promote the use of Be worth.
