Description

Bellows multiple sealing quick joint

Technical Field

The utility model relates to a quick-connect joint, specifically say a bellows multiple seal quick-connect joint.

Background

The quick-connection joint for the pipelines is an important link in pipeline connection, and can quickly realize splicing, shunting and the like of the pipelines; wherein, the bellows quick joint in the conventional structure, though solved the quick problem of connecing, but the leakproofness has hidden danger, for example the port position that the bellows pegged graft in the joint appears the dislocation easily, leads to the not good problem of leakproofness, and this situation exists: when the water pressure exceeds the bearing limit, the swinging end of the pipeline is staggered to form a gap.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned drawbacks of the prior art, the present invention is directed to: a bellows multiple seal quick connect coupling is provided.

The technical solution of the utility model is that: bellows multiple seal connects soon, including the bellows that cup joints the leather hose and the coupling assembling of connecting the bellows, coupling assembling includes pullover and closes the head soon with pullover threaded connection, and the bellows stretches into pullover and closes in the head soon, be equipped with snap ring, clamping ring and the rubber circle that distributes from interior to exterior in proper order between pullover front end inner wall and the bellows front end outer wall, the rear end of closing the head soon has the storage tank, has a ring that is used for compressing tightly the preceding terminal surface of rubber circle in the storage tank, and the card has a sealing washer that is used for compressing tightly the preceding terminal surface of bellows in the ring.

Furthermore, a rubber ring is clamped in the rear end of the sleeve head, and the end part of the leather hose is clamped between the rubber ring and the corrugated pipe.

Furthermore, an annular groove for clamping the rubber ring is formed in the inner wall of the rear end of the sleeve head.

Furthermore, the ring separates the storage tank to form a limiting groove located on the outer side of the ring and a clamping groove located on the inner side of the ring, the sealing ring is placed in the clamping groove, the front end of the corrugated pipe is clamped in the clamping groove, and when the front end of the sleeve head is screwed and screwed, the front end of the sleeve head is clamped in the limiting groove.

Furthermore, snap ring, clamping ring and rubber circle all overlap on bellows front end outer wall, and the clamping ring card is between snap ring and rubber circle, and snap ring chucking bellows, when the pullover with close soon the head and screw the back, the ring extrusion rubber circle front end.

Use the utility model provides a bellows multiple seal connects soon, its beneficial effect is: after the front end of the corrugated pipe is contacted with the sealing ring, a first heavy sealing structure is formed; the ring compresses tightly the back with the rubber circle and forms the second and heavily seals the structure, and the rubber circle is by the ring extrusion back, and the rubber circle is inboard all can expand with the outside for the rubber circle can more closely with the contact bellows, further improved sealed effect.

Shown in the figure: the rubber tube comprises a rubber tube body 1, a rubber tube body 2, a corrugated tube body 3, a sleeve head 31, a groove 4, a screwing head 41, an accommodating groove 411, a limiting groove 412, a clamping groove 42, a circular ring 5, a clamping ring 6, a pressing ring 7, a rubber ring 8, a sealing ring 9, a rubber ring 10 and a limiting ring.

Detailed Description

For a more intuitive and complete understanding of the technical solution of the present invention, the following non-limiting characteristic description is now performed by combining the drawings of the present invention:

as shown in fig. 1 to 5, the socket 3 and the screwing head 4 in fig. 1, 2 and 3 are in an unscrewed state, and a stop ring 10 is sleeved outside the socket 3, and the stop ring 10 is removed when the socket 3 and the screwing head 4 are screwed. Bellows 2 multiple seal connects soon, including the bellows 2 that cup joints leather hose 1 and connect bellows 2's joint Assembly, joint Assembly includes pullover 3 and closes head 4 soon with pullover 3 threaded connection, bellows 2 stretches into pullover 3 and closes in the head 4 soon, be equipped with the snap ring 5 that distributes from interior to exterior in proper order between pullover 3 front end inner wall and the 2 front end outer walls of bellows, clamping ring 6 and rubber circle 7, the rear end that closes head 4 soon has storage tank 41, it is used for compressing tightly the ring 42 of rubber circle 7 preceding terminal surface to have one in the storage tank 41, the card has a sealing washer 8 that is used for compressing tightly the preceding terminal surface of bellows 2 in the ring 42. The front end of the corrugated pipe 2 is contacted with the sealing ring 8 to form a first heavy sealing structure; the circular ring 42 and the rubber ring 7 are tightly pressed to form a second re-sealing structure.

A rubber ring 9 is clamped in the rear end of the sleeve head 3, the end part of the leather hose 1 is clamped between the rubber ring 9 and the corrugated pipe 2, and an annular groove 31 for clamping the rubber ring 9 is arranged on the inner wall of the rear end of the sleeve head 3. The leather hose 1 is clamped between the corrugated pipe 2 and the rubber ring 9, and the rubber ring 9 extrudes the leather hose 1, so that the leather hose 1 is contacted with the corrugated pipe 2 more tightly, and the sealing effect is achieved.

The ring 42 partitions the receiving groove 41 into a limiting groove 411 located on the outer side of the ring 42 and a clamping groove 412 located on the inner side of the ring 42, the sealing ring 8 is placed in the clamping groove 412, the front end of the corrugated pipe 2 is clamped in the clamping groove 412, and when the front end of the sleeve head 3 is screwed and the rear end of the screwing head 4 is screwed, the front end of the sleeve head 3 is clamped in the limiting groove 411. Snap ring 5, clamping ring 6 and rubber circle 7 all overlap on 2 front end outer walls of bellows, and clamping ring 6 card is between snap ring 5 and

rubber circle

7, and 5 chucking bellows 2 of snap ring, after pullover 3 screwed with closing head 4 soon, 7 front ends of rubber circle are extruded to ring 42. After the rubber ring 7 is pressed by the ring 42, both the inside and the outside of the rubber ring 7 are expanded, so that the rubber ring 7 can be brought into closer contact with the corrugated tube 2.

It is to be understood that the foregoing is only a preferred embodiment of the present invention, and not intended to limit the scope of the invention, which is defined by the following claims and drawings.
