Technical Field

The utility model relates to a sealing joint, specifically say a simple and easy sealing joint of bellows.

Background

The structure of the bellows sealing structure generally comprises a joint component sleeved with a bellows, in order to improve the sealing performance of the joint component after being connected with the bellows, sealing treatment needs to be carried out through the sealing structure, and the sealing structure is often too complex in structure.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned drawbacks of the prior art, the present invention is directed to: a simple sealing joint for corrugated pipes is provided.

The technical solution of the utility model is that: simple and easy sealing joint of bellows, including the joint Assembly who cup joints the bellows, joint Assembly includes the adapter, and the rear end of this adapter has intubate, sloping platform and the screw thread portion that distributes in proper order from the back to the front, and the cover has a sealing ring that matches rather than the shape on the sloping platform outer wall, and during the intubate inserted the bellows, the sealing ring pressed on bellows port inner wall, the cover has the snap ring of constituteing by two fixture block concatenations on the tip outer wall of bellows, has revolved a adapter sleeve on the adapter rear end screw thread portion, and the adapter sleeve is pressed on the fixture block outer wall.

Furthermore, the inner wall of the sealing ring is attached to the outer wall of the inclined table, and the outer wall of the sealing ring is pressed on the inner wall of the port of the corrugated pipe.

Further, the inner wall of fixture block and the laminating of bellows outer wall.

Furthermore, a plurality of grooves are formed in the inner wall of the clamping block, convex rings matched with the grooves are arranged on the outer wall of the end part of the corrugated pipe, and the convex rings are clamped in the grooves.

Furthermore, the front end of the clamping block is provided with an arc-shaped convex strip which protrudes outwards, the rear end of the fastening sleeve is provided with a convex ring which extends inwards, and the convex ring is contacted with and props against the rear end of the arc-shaped convex strip.

Use the utility model provides a simple and easy sealing joint of bellows, its beneficial effect is: after the sealing ring sleeved on the ramp is tightly contacted with the inner wall of the port of the corrugated pipe, the clamping ring formed by splicing the two clamping blocks is pressed by the fastening sleeve, so that the clamping ring applies pressure to the corrugated pipe and can tightly press the corrugated pipe, the corrugated pipe can be more tightly contacted with the sealing ring after being pressed, and the sealing effect is better.

FIG. 2 is an exploded view of the present invention;

fig. 3 is a schematic cross-sectional view of the present invention;

FIG. 4 is a schematic structural view of the fixture block of the present invention;

fig. 5 is a schematic structural view of the fastening sleeve of the present invention.

The following are shown in the figure: the sealing structure comprises a corrugated pipe 1, a convex ring 11, a connector 2, an insertion pipe 21, an inclined platform 22, a threaded part 23, a sealing ring 3, a clamping ring 4, a clamping block 41, a clamping block 411, a groove 412, an arc-shaped convex strip 5, a fastening sleeve 51 and a convex 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. 1-5, the simple sealing joint for corrugated pipe, including the joint assembly that cup joints corrugated pipe 1, the joint assembly includes adapter 2, this adapter 2's rear end has intubate 21, sloping platform 22 and screw thread portion 23 that distribute in proper order from the back to the front, the cover has a sealing ring 3 that matches rather than the shape on the sloping platform 22 outer wall, intubate 21 inserts in corrugated pipe 1, sealing ring 3 presses on the inner wall of corrugated pipe 1 port, the cover has snap ring 4 that comprises two fixture blocks 41 concatenation on the tip outer wall of corrugated pipe 1, adapter 2 rear end screw thread portion 23 has a adapter sleeve 5 on the top, adapter sleeve 5 presses on the fixture block 41 outer wall.

The clamping ring 4 is formed by splicing two clamping blocks 41 with the same shape, so that the clamping ring 4 is conveniently sleeved outside the corrugated pipe 1.

The inner wall of the sealing ring 3 is attached to the outer wall of the ramp 22, the outer wall of the sealing ring 3 is pressed against the inner wall of the port of the bellows 1, and the sealing ring 3 is preferably a metal ring.

The inner wall of the fixture block 41 is attached to the outer wall of the corrugated pipe 1. In order to make the inner wall of the latch 41 closely fit the outer wall of the corrugated tube 1, the inner wall of the latch 41 has a plurality of grooves 411, the outer wall of the end of the corrugated tube 1 has a collar 11 matching the grooves 411, and the collar 11 is snapped into the grooves 411.

The front end of the latch 41 has a convex arc-shaped protrusion 412, the rear end of the fastening sleeve 5 has an inwardly extending protrusion ring 51, and the protrusion ring 51 contacts and abuts against the rear end of the arc-shaped protrusion 412. When the fastening sleeve 5 is screwed with the adapter 2, the fastening sleeve 5 moves forward, so that the convex ring 51 of the fastening sleeve 5 can apply a forward thrust to the arc-shaped convex strip 412 of the fixture block 41, so that the corrugated pipe 1 is also pushed against the sealing ring 3 after receiving the forward thrust, and the corrugated pipe 1 is in contact with the sealing ring 3 more tightly.

The utility model discloses a cover sealing ring 3 on sloping platform 22 and 1 port inner wall of bellows closely contact the back, the snap ring 4 of constituteing by two fixture block 41 concatenations is being pressed to rethread fastening cover 5 for the snap ring 4 exerts pressure to bellows 1 and can push down bellows 1 tightly, thereby can contact with sealing ring 3 more closely after making bellows 1 pressurized.

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.
