Abstract

The utility model provides a pipe joint of an inserted elastic clamping ring, which is composed of a joint, elastic clamping ring, and a sealing cap, wherein the elastic clamping ring is arranged between the joint and the sealing cap, and the joint is connected with the sealing cap together. The elastic clamping ring is provided with an opening, and one end of the elastic clamping ring is an outer conical surface. An inner hole of the elastic clamping ring is provided with a clamping edge opening with a zigzag cross section, and one side of the edge opening is a conical surface. The excircle of the sealing cap is provided with an outer sealing groove, and an inner hole is provided with an inner sealing groove. The bottom surface of the inner sealing groove is a conical surface, and the inside of the sealing groove is provided with a sealing ring. One end of the sealing cap is an inner conical surface which is matched with an outer conical surface on the elastic clamping ring, and one end of an inner hole of the joint is a conical surface. The utility model uses the outer sealing between the sealing cap and the joint and the inner sealing between the sealing cap and a pipe and has the advantages of simple structure and good sealing effect. The clamping edge opening in the elastic clamping ring causes the pipe to be passed through in a unidirectional form, and the pipe is difficult to retreat. The utility model has high safety.

Description

Inserting elastic snap ring pipe joint

(1) technical field:

The utility model relates to inserting type pipe joint.

(2) background technique:

At present, connect the inserting type pipe joint complex structure that pipe is used, its structure is beneficial to fast quick-detach.Because take into account fast quick-detach, thus on the reliability of pipe locking, there is deficiency, and sealing effect is poor.Just because of pipe can be extracted fast, make the ease of connection between the pipe throw off poor stability.

(3) summary of the invention:

At above the deficiencies in the prior art, the utility model provides the inserting elastic snap ring pipe joint of a kind of simple in structure, good airproof performance, high safety.

The solution that the utility model adopts is:

Inserting elastic snap ring pipe joint is made up of fittings body, snap ring and sealed cap, and snap ring is installed between fittings body and the sealed cap, and fittings body and sealed cap link together; Have opening on the snap ring, the one end is a male cone (strobilus masculinus), is provided with the chucking cutting edge of cross section indention in its endoporus, and this cutting edge one side is the conical surface; The cylindrical of sealed cap is provided with the external sealed groove, is provided with interior seal groove in the endoporus, and the bottom surface of interior seal groove is the conical surface, is provided with seal ring in the seal groove, and an end of sealed cap is an inner conical surface, cooperates with male cone (strobilus masculinus) on the snap ring; Endoporus one end of fittings body is a conical surface, with the seal ring formation sealing in the sealed cap cylindrical seal groove.

External sealed between the utility model employing sealed cap and the fittings body and the interior sealing between sealed cap and the pipe, and interior seal groove employing taper bottom surface, the external sealed face adopts internal conical surface, and is simple in structure, good sealing effect.Snap ring is provided with zigzag fashion chucking cutting edge, and pipe can only unidirectionally be passed through, and is difficult for withdrawing from high safety.

(5) embodiment:

Embodiment:

Fig. 1 has provided structural representation of the present utility model.This inserting elastic snap ring pipe joint is made up of fittings body 1, snap ring 2 and sealed cap 4, and snap ring 2 is installed between fittings body 1 and the sealed cap 4, and fittings body 1 and sealed cap 4 are by being threaded togather.Fig. 2 and Fig. 3 have provided the structural representation of snap ring 2.Have opening 14 on the snap ring 2, it is opened and tighten up; Its right-hand member is a male cone (strobilus masculinus) 12, produces the radial compaction power that tightens pipe with the inner conical surface 16 with sealed cap 4; Be provided with the chucking cutting edge 10 of cross section indention in its endoporus, this cutting edge one side is the conical surface 11, makes the pipe 7 can only be from the conical surface 11 unidirectional passing through.Be provided with plane 13 in the outside on opening 14 opposites and make wall thickness attenuation herein, so that snap ring 2 has the outer surface of enough elasticity chucking pipes 7, both sides do not have the ring wall of attenuation then to have enough rigidity.Fig. 4 has provided the structural representation of sealed cap.Sealed cap 4 adopts screw thread to be connected with fittings body 1, and convenient disassembly has guaranteed connection reliability and mechanical strength.Two interior seal grooves and an external sealed groove are arranged on the sealed cap 4, and its left end has inner conical surface 16, with the reliable firm coupling mechanism force of having guaranteed pipe that cooperates of the male cone (strobilus masculinus) 12 of snap ring 2.Realize simple and effective external sealed by O RunddichtringO 3 between the internal conical surface of external sealed groove and fittings body 1 right-hand member; the internal conical surface of fittings body 1 right-hand member is along with screwing of sealed cap 4 can compress O RunddichtringO 3 gradually; strengthened sealing; when assembling, protected seal ring not to be damaged again; taken into account axial and radial seal, sealed more reliable.Realize interior sealing by O RunddichtringO 5 and 6 between interior seal groove and the pipe 7, conical surface 15 is adopted in the bottom surface of two interior seal grooves, and its width suitably strengthens, and has made things convenient for assembling.Especially after fittings body 1 passes through pressure medium, the working pressure of medium is pressed onto medium to produce on the left side of 0 RunddichtringO moving to the right, and the bottom land internal conical surface of seal groove diameter is more little more to the right, increase along with pressure, the O RunddichtringO also increases the radial pressure of pipe 7, thereby improved the sealing effect between sealed cap 4 and the pipe 7, after the wearing and tearing of O RunddichtringO, had the effect of automatic compensation sealing.Fittings body 1 can have the pipe joint interface of the different patterns of a plurality of different-diameters.

During use, the port of pipe 7 is inserted by sealed cap 4, and the pipe front end arrives the conical surface 11 of snap ring 2 right-hand members chucking cutting edge 10 through seal ring 5 and 6.The left side of snap ring 2 is withstood by the snap ring locating face 8 in the fittings body 1.Pipe 7 front ends continue to insert forward and snap ring 2 will be strutted, and the chucking cutting edge 10 that passes snap ring 2 arrives the pipe locating face 9 of fittings bodies 1, and pipe 7 inserts and puts in place,, can not throw off, leak during less than 1mpa in the pressure medium working pressure.Tighten the outer surface that cutting edge 10 has snapped in pipe 7 this moment, makes pipe 7 can not withdraw from snap ring 2.The effect of snap ring 2 is exactly that pipe 7 can only unidirectionally be passed through.If pipe 7 is withdrawed to the right, snap ring 2 can move right with pipe 7, and the power of radially holding tightly that the male cone (strobilus masculinus) 12 of snap ring 2 right-hand members produces snap ring 2, it is tight more that snap ring 2 is blocked pipe 7 more, can not withdraw from.Therefore, the utility model high safety, pipe 7 is difficult for deviating from.The pipe 7 of packing into if dismantle must be backed out sealed cap 4 and pipe 7 is released sealed cap 4 left take snap ring 2 out of, and the opening 11 that struts snap ring 2 again takes off it, can pull out pipe 7 to the right.
