Abstract

The utility model relates to a fast joint which belongs to a pipeline component. The fast joint comprises two sections of pipe bodies (1, 5), wherein the sections of one end of the pipe bodies are respectively connecting sections which can be connected with the inlet connecting end and the outlet connecting end of a pipeline which needs to be connected, and the sections of the other ends are respectively made into structures which can make the two pipe bodies inserted mutually to form a shape required by a sheathed pair (6) with a sealing component (2). The sheathed and matched position of the pipe end of an outer pipe, which is near to a sheathed state is provided with an axis line which is vertical to a center line of each pipe body, a lock pin hole (3) which is cross with the inner pipe and does not penetrate through the inner wall of the inner pipe, and a lock pin (9) which is arranged in the lock pin hole (3) and is provided with an eccentric limit section (4) and a handle (7); in addition, the distance of the axis line and the center line is larger than a half of the outer diameter of the inner pipe. The fast joint has the advantages of fast connection and separation, reliable work, convenient fabrication, convenient use and easy maintenance.

Description

Rapid pipe joint

The utility model belongs to pipeline fittings, relates generally to the structure of pipeline connecting joint.

Known rapid pipe joint has realized the on-the-spot connection of the higher pipeline of maneuverability requirement for the connection of pipeline provides multiple easy way; And multiple requirement has been satisfied in the new continuous appearance of joint from different perspectives.

The purpose of this utility model is the organization plan that proposes a kind of quick coupler.

The purpose of this utility model is achieved in that rapid pipe joint comprises two sections bodys, and one end section is respectively to go out the connecting section that joining end into links with road to be taken over; In addition end is made respectively and is connected two bodys, sets up and wait to take over path between the road, dismounting and connect secondary required shape easily, the sealing pair that links respectively with adjacent adapter, and the fixing seal parts that connect above-mentioned parts.Wherein, described connection pair is to make two bodys hold the socket pair that links of mutual socket joint in addition; Sealed member is loaded between the socket fitting surface of pipe pipe end in the nearly socket; At the position of the secondary nearly outer tube pipe end of socket, be provided with axis normal body center line, axis and distance between center line greater than interior external diameter of pipe half, all crossing but do not penetrate the lockpin hole of inner tube wall with two tube wall fitting surfaces; Promptly by the common circular hole of forming of the shape of tube wall inside and outside this place's socket section; With cooperate fixing lock pin with this hole.Like this, described connecting section is through connecting with pipeline to be joined, and can make described body conduct wait to take over the turnover joining end of the rapid pipe joint on road; The connection that socket socket joint, sealing can be set up the two; Lock pin in the described lockpin hole can stop the relative movement between Coupling, becomes the state that is fixedly connected of this programme.Remove described lock pin spacing to two bodys in the use, the socket joint socket that just can decompose two bodys easily realizes the separation that connects.Socket of being adopted and lock pin all be easy to realize, positive connection form easy and simple to handle; Radial seal is the supporting structure that realizes cylinder fitted seal in the socket.Thereby the purpose of this utility model is achieved.

During rigging position described in the utility model in lock pin and the socket pipe superposed part be removed, the surplus part in this place is spacing section, it is with the remaining part of lock pin and described lockpin hole is hinged links, and the part of lock pin outside the hole is shaped on operating handle and axially locating jump ring.Like this, the part of removing still Bao Te pipe is interior unimpeded, and makes surplus part form off-centre; Hinged and handle is convenient to operation, but the jump ring axial limiting makes spacing section conversion that realizes easily between spacing and releasing two positions.

The utility model has been realized the connection and the decomposition of pipeline very quickly by the socket join structure of the eccentric lock pin of easy band, and radial seal can guarantee to connect reliable.The joint structure of this programme is simple, the manufacturing use is all very convenient, and is easy to safeguard.

Accompanying drawing provides the utility model embodiment signal.

Fig. 1 is the joint structure diagrammatic sketch;

Fig. 2 is the joint outline drawing;

Fig. 3 is that the A-A of Fig. 1 analyses and observe.

The utility model is described in further detail below in conjunction with embodiment.

Fig. 1-3 is seen in first embodiment's rapid pipe joint.Comprise that as the two sections bodys 1,5 among Fig. 1, its water outlet body 1 one ends can fixedly link with flexible pipe, with the solid two-part connection of larynx banding, water inlet body 5 one ends link with treating connection pipe waterexit end, and the body radial dimension is determined by actual demand.Holding by outlet pipe 1 outside in addition of two sections bodys, intake pipe 5 are interior, and socket joint becomes socket to cooperate each other.In cooperating section 6, be equipped with and prevent by cooperating section to reveal the U RunddichtringO 2 of liquid in the pipe.Outer socketed pipe beyond the seal ring outboard end, be shaped on that axis normal adapter, internal surface and socket fitting surface intersect but the pin-and-hole 3 that do not penetrate institute's connecting tube 5 internal surfaces, the annular groove consistent with above-mentioned pin-and-hole 10 then should be made in the relevant position of interior socket intake pipe 5 outer walls, see Fig. 3, annular groove is positioned at the part of pin-and-hole position, can partly constitute complete pin-and-hole internal surface with the pin-and-hole on the pipe 1.In pipe 1 pin-and-hole 3, be equipped be slidingly matched, an end with handles 7 and the bearing pin 9 of end band jump ring 8 in addition, see Fig. 2.The part of bearing pin in the hole made; Fix, when being the disengaging configuration, as Fig. 1,3 double dot dash lines, allow the axial relative movement of two socketed pipes when handle is in one, that is to say that bearing pin 9 influences the part of relative movement, the part of socketed pipe outside cylinder is removed in promptly entering; When handle be in other half cycle fixed position, when being locked position, as Fig. 1,3 solid lines and dotted line, the not removed part of bearing pin 9 then, with on interior socketed pipe 5 outer surfaces, the annular groove that is positioned at the pin-and-hole place matches, socket is locked then.The lock pin axle head is equipped with the jump ring 8 of its axially locating, sees Fig. 2,3.More than be that this routine structure is described.Before the use, with this joint two bodys respectively with wait that picking out feed-water end fixedly links, in outlet pipe lockpin hole 3, insert lock pin 9, fix it by jump ring 8 axle heads, and in outlet pipe import sector hole 3 axially with interior position dress seal ring 2, the cost example treat coupled situation.

During use, when handle is removed to above-mentioned disengaging configuration, interior socket intake pipe 5 just can insert in the outer socketed pipe 1, when the position of socketed pipe annular groove 10 and outer socketed pipe part pin-and-hole 3 matches in treating, handle can be threaded to locked position, then overlap termination process and promptly come to an end, realize the connection of joint.At this moment adorn the sealing that U RunddichtringO 2 can guarantee that the section of cooperation is interior.When needs are disassembled, lock pin handle 7 is threaded to the disengaging configuration, the interior socketed pipe 5 of socket just can be extracted out, separates and finishes at once.The operation of this example is very easy, because of the buffer action of radial seal, can guarantee that coupled situation is normal, work does not have leakage.
