Description
Technical field
The utility model relates to the member that a kind of drainage pipe is used, and is specifically related to a kind of novel bayonet joint pipe fitting.
Background technique
Drainage pipe application in daily life is very extensive, in the water supply and sewerage pipeline of the indoor and outdoors such as industrial premises, civil building, the normal bayonet joint pipe fitting that adopts, these adopt the pipe fitting of socket joint Placement usually to be comprised of various materials, and especially the socket joint Placement is used more extensive in plastic pipe.For pipe laying with prevent pipe leakage, all in pipe fitting inner wall and pipeline outer wall spreading glue, when glue is second-rate, sealing can go wrong, when the glue quality was better, can produce pipe fitting can only disposable problem, in case error or leak and must use new pipe fitting to reinstall, this has not only wasted tubing, has also increased installation cost.
One " the spigot and socket type device that tubing is connected with pipe fitting " by name, notification number is CN 22558834 U, the day for announcing is that the Chinese utility model patent on July 2nd, 2003 discloses a kind of spigot-and-socket connector.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, connects locking by nut.This connection set complicated structure, special to the structural requirement of tubing and pipe fitting, the preparation of tubing and pipe fitting is had relatively high expectations.
The model utility content
The purpose of this utility model is linkage structure complexity and connection complexity and the not re-usable problem that solves between tubing and tubing, tubing and the pipe fitting, and a kind of simple in structure, convenient installation and reusable connection pipe fitting is 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 novel insertion connector, comprise connecting tube, seal ring and friction top, joint in the middle of described connecting 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, the joint of department of assembly and joint forms step, seal ring and friction top all match with the department of assembly, and seal ring is positioned on the step of connecting tube, and friction top is fixedly connected with connecting tube.
Come two tubing or pipe fitting are connected the structure that has advantages of flexible structure, also can simplify tubing and pipe fitting by introducing link.Insertion connector by connecting tube, seal ring and friction top consist of is fixed by simple clamping, and is easy and simple to handle, and breaks away from the dependence of glue by seal ring, and insertion connector can repeatedly be used.
As preferably, described department of assembly is conical pipe, and the diameter of port, department of assembly is less than the diameter of department of assembly and joint joint.Conical pipe shrinks gradually, and the contraction design of department of assembly can make things convenient for the compression of associated friction top, and friction top can closely cooperate with the outer wall of department of assembly in the process that compresses, and increases sealing and fastness.
As preferably, the inwall of friction top is provided with snap ring, and friction top is by snap ring and connecting tube clamping.
As preferably, be provided with an assembling bulge loop near the step place on the described connecting tube outer wall, assembling bulge loop and step form assembly cavity, and snap ring carries out clamping by embedding assembly cavity.The assembling bulge loop can be used for cooperating with the snap ring of friction top inwall with the assembly cavity that step forms, and when friction top compressed, snap ring embedded and realizes fixed function in the assembly cavity.
As preferably, be provided with position limiting convex ring in the middle part of the inwall of connecting tube.The position limiting convex ring of connecting tube inwall setting can to manage interior pipe fitting carry out spacing, the pipe fitting insertion depth that prevents from the managing interior both sides sealing of the causing variation that has big difference.
As preferably, described friction top is provided with mounting hole, and mounting hole is provided with the guide pipe that matches with mounting hole.The mounting hole of friction top is to pass tubing and the pipe fitting that need to connect, and it is coaxial that the guide pipe that arranges on the mounting hole is that orientation and the connecting tube of the tubing that connects in order to ensure needs or pipe fitting is in, prevent and connecting tube between form the gap.
Owing to adopting technique scheme, the beneficial effect of a kind of novel bayonet joint pipe fitting of the present utility model is, by adopting novel insertion connector, the tubing that need to connect or the structure of pipe fitting have been simplified, this bayonet joint pipe fitting is simple in structure but also simple installation not only, can realize repeatedly using.
