Background technique
Drainage pipe application in daily life is very extensive, and in the water supply and sewerage pipeline of the indoor and outdoors such as industrial premises, civil building, bayonet joint is the normal Placement that adopts of the pipe fitting in the drainage pipe.For pipe laying with prevent that pipeline from revealing, good sealing is particularly important.Connection and the bayonet joint pipe fitting of present pipeline, usually the mode that adopts is to reach sealing effect in the joint of the pipe fitting that connects spreading glue mode, adopt glue to have many drawbacks, on the one hand, when the glue quality can not get effective guarantee, the sealing effect will go wrong, on the other hand, when the glue quality is better, since glue be difficult to remove caused pipe fitting to occur can only disposable problem, in case owing to when error or the pipe fitting that need more renew, just be difficult to carry out, not only waste tubing, also increased installation cost.In addition, the connection procedure of these pipe fittings is because operation is more, and complicated operation is installed inconvenience.
One " the spigot and socket type device that tubing is connected with pipe fitting " by name, notice of authorization number discloses a kind of spigot-and-socket connector for the Chinese utility model patent of CN 2558834 Y, it comprises pipe fitting, screw thread neck bush, nut, O type circle, jump ring, sealer, tubing, groove, by the screw thread neck bush being screwed in tubing one end with internal thread, be rolled into groove at tubing one end, jump ring is inserted in the groove, O type snare enters in the middle of the screw thread neck bush, end at tubing is coated with the last layer sealer, at last tubing is inserted in the pipe fitting, connect locking by nut.This connection set is complicated structure on the one hand, and complicated inconvenience is installed, and is special to the structural requirement of tubing and pipe fitting, on the other hand, owing to adopt glue sealing, caused the not reproducible usability of pipe fitting.
The model utility content
The purpose of this utility model is that to solve in the drainage pipe linkage structure between the tubing and tubing complicated and need to seal with glue and cause the pipe fitting mounting structure is required height, operation inconvenience, changes the problems such as inconvenience, and a kind of simple in structure, easy for installation, good sealing effect and reusable pipeline spigot-and-socket formula Quick connector are provided.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of pipeline spigot-and-socket formula Quick connector, comprise main body tube, seal ring and friction top, friction top and main body tube clamping, form an assembly cavity between main body tube outer wall and the friction top inwall, seal ring comprises fixing part and sealed department, the joint of fixing part and sealed department forms the draw-in groove that an end with main body tube matches, seal ring is by draw-in groove and the clamping of main body tube end, fixed position is in assembly cavity, and seal ring and main body tube and friction top all match.
In the technical program, abandoned traditional mode that seal ring only is set at inside pipe fitting, but the structure of seal ring has been carried out the expansion performance, increase and designed fixing part, and fixing part is placed in the assembly cavity of friction top and the formation of main body tube outer wall, not only the position of seal ring is fixed, and increased the sealing effect of friction top and main body tube, stopped the leakage between friction top and the main body tube, on the other hand, the sealed department of seal ring has reached sealing effect to having carried out gap-fill between the connection pipe fitting in managing and the main body tube.Dual Seal Design has played good sealing effect, thereby has given up the glue sealing operation.
As preferably, the joint in the middle of described main body tube comprises and the department of assembly on both sides, the internal diameter of department of assembly is greater than the external diameter of joint, and joint is fixedly connected with the department of assembly, the inwall formation step of joint and joint, department of assembly.The inwall of the joint of department of assembly and joint forms step, and this step can be used for placing the sealed department of seal ring, and sealed department and the step of seal ring match, further increased the pipe fitting that is connected with main body tube and main body tube between sealing.
As preferably, sealed department is provided with the sealing ripple.The sealing ripple can better be filled the pipe fitting that is connected and the gap between the main body tube, increases sealing effect.
As preferably, the outer wall of department of assembly is provided with position limiting convex ring, and the relevant position of friction top inwall is provided with the limited location snap ring that matches with position limiting convex ring, and friction top is by limited location snap ring and position limiting convex ring and department of assembly's clamping.Friction top can be by being stuck in limited location snap ring the clamping of carrying out on the position limiting convex ring with main body tube.
As preferably, the outer wall of described department of assembly is provided with anti-open portion, and anti-open-part forms a limit chamber in the side of position limiting convex ring away from the end, department of assembly between anti-open portion and the position limiting convex ring, and limit chamber and limited location snap ring match.After friction top and the position limiting convex ring clamping; limited location snap ring can embed in the limit chamber; friction top is fixed; simultaneously; have the slit between the side wall ends edge meeting of friction top and main body tube, thereby the limited location snap ring that this slit causes external substance to enter easily forces friction top easily slippage from position limiting convex ring out causes locking to lose efficacy; anti-open portion has been carried out second protection to limited location snap ring, has increased the fastness of limited location snap ring.
As preferably, the top of described friction top is provided with mounting hole, and the edge of mounting hole forms a semiclosed cavity to lower recess and with the sidewall of friction top, and the fixing part of semiclosed cavity and seal ring matches.Mounting hole is that the internal layer pipe fitting of the two-layer pipe fitting that will be connected therefrom passes, thereby with friction top and main body tube locking, the semiclosed cavity that forms can be placed the fixing part of seal ring and jointly the fixing part of seal ring is fixed with the department of assembly, thereby friction top and main body tube time are sealed.
As preferably, friction top is cone structure.Cone structure is convenient to friction top and when clamping limited location snap ring is snapped in the position limiting convex ring.
As preferably, be provided with the spacing preiection that is fixedly linked with the main body tube inwall in the middle part of the inwall of main body tube.The spacing preiection at main body tube inwall middle part can guarantee that two connection pipe fittings at two ends in the pipeline spigot-and-socket formula Quick connector have identical deep amount, avoids the pipe fitting of an end deeply too much the pipe fitting of the other end to be ejected outside the main body tube.
Owing to adopt technique scheme, the beneficial effect of pipeline spigot-and-socket formula Quick connector of the present utility model is: the 1 double seal design by seal ring makes integral body reach good sealing effect, 2 have simplified the structure of one-piece element, fitting operation is easier, 3, given up the use of glue, so that installation procedure is easier, the more new for old of 4 pipe fittings is more convenient to operate feasible, has avoided the destruction problem of glue to pipe fitting.
