Abstract
The utility model relating to an express connector for plastic conduits is a pipe connection device. A cylinder-shaped O-ring seal is located in two metal blocking tops which are locked with each other. Circumference of two sides of the metal blocking tops is provided with a capped edge to block the O-ring seal. Inner side of the O-ring seal is a conduit cavity, and axial center of the O-ring seal is provided with an inward raised sealing boss. The utility model with simple structure, easy operation, well sealing property, and fastened joint, can save both time and labor, complete the operation rapidly, and get widely application prospect.
Description
Technical field
The utility model relates to a kind of plastic pipe rapid pipe joint, is the pipe jointer tool.
Background technique
Along with expanding economy, the increasing of construction engineering, the application of plastic pipe also more and more widely, its installation, laying amount are increasing, therefore, the connection of plastic pipe seems and is even more important.What tradition adopted is flange connection, utilizes pipeline flanges, by metal flange, compresses, connects by a plurality of connecting bolts, and constructing operation is loaded down with trivial details, wastes time and energy, and is very inconvenient, and the cost height.The multiple quick link that has occurred pipeline immediately provides convenience for connecting fast, as the wedging linkage structure of tilting, or the like, still have complex structure, operate loaded down with trivial details, awkward shortcoming, have after implement connecting, also have the problem of sealing effect difference, cause pipeline medium to be revealed.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of simple in structure, use easy to operate, the plastic pipe rapid pipe joint of good seal performance.
Plastic pipe rapid pipe joint described in the utility model has seal ring, and its cylindric O-ring seal places two metal card lids of mutual snapping, and two side peripheries of metal card lid are provided with the rib of block O-ring seal, and the O-ring seal inboard is a tube cavity.
The utility model is made up of O-ring seal and metal card lid, and is simple in structure, uses easy to operate.When construction was used, the connecting end of the pipeline that needs are connected was inserted in the O-ring seal, is placed in arbitrary semicircle metal card lid, then second half circular metal Ka Gai is buckled, and the bolt connecting hole that covers mutual snapping by metal card connects with connecting bolt to be finished.The area of contact of cylindric O-ring seal and connecting tube is big, through compress fastening after, good sealing effect has thoroughly solved the leakage problem of pipeline medium.
The seal boss of projection is to the inside set up in the axial intermediate portion of O-ring seal, and two road enhanced leaktightness are implemented to the mouth of pipe contact position of connecting tube in the mouth of pipe position of the corresponding connecting tube of this boss, can further strengthen sealing effect.
Be designed to concavo-convex surface of contact between metal card lid and O-ring seal, projection on the O-ring seal and the corresponding contact of groove that metal card covers form the contact of curved surface warpage, can strengthen sealing effect, increase join strength.
The O-ring seal rib of metal card lid outside inboard being higher than of designing, is convenient to improve the tight pressing of rapid pipe joint and connecting tube, is beneficial to the good sealing of acquisition and is connected effect.
The utility model is simple in structure, uses easy to operately, and good seal performance is connected firmly, and is time saving and energy saving again, can finish constructing operation fast, has broad application prospects.
Description of drawings
Fig. 1, the structural representation of the utility model one embodiment under application state.
Among the figure: 1, an end connecting tube 2, metal card lid 3, metal card lid snapping attachment hole 4, O-ring seal 5, O-ring seal boss 6, rib 7, the other end connecting tube 8, metal card lid groove.
Embodiment
The utility model is described in further detail in conjunction with the foregoing description accompanying drawing.
As shown in the figure, plastic pipe rapid pipe joint described in the utility model, its cylindric O-ring seal 4 places two metal card lids 2 of mutual snapping, two side peripheries of metal card lid 2 are provided with the rib 6 of block O-ring seal 4, the seal boss 5 of the oriented inner bulge in axial intermediate portion of O-ring seal 4, metal card lid 2 is designed to concavo-convex surface of contact with 4 of O-ring seals, and the projection on the O-ring seal 4 and metal card are covered the groove 8 corresponding contacts on 2.O-ring seal rib 6 inboards of metal card lid 2 are higher than the outside.
During construction application, the connecting end of the pipeline 1,7 that needs are connected is inserted in the O-ring seal 4, its mouth of pipe is corresponding with boss 5 positions, O-ring seal 4 is placed in arbitrary semicircle metal card lid, then second half circular metal Ka Gai is buckled, the bolt connecting hole 3 usefulness connecting bolts connection that covers mutual snapping by metal card is finished.
