FIG. 2 is a top view of FIG. 1;

FIG. 3 is a schematic view of the use of the eccentric coupling device shown in FIG. 1;

in the figure: 1. the anti-skid pipe comprises a first bearing pipe body, 11, an annular bulge, 12, an annular groove, 13, a first limiting boss, 2, a second bearing pipe body, 21, a second limiting boss, 22, an anti-skid groove, 3, a transition pipe, 4, a first vertical pipe, 5, a second vertical pipe, 6 and a sealing element.

Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Example one

Referring to fig. 1-2, the embodiment discloses an eccentric connecting device for a pipeline, which includes a first adapting pipe 1 and a second adapting pipe 2 that are communicated with each other, the first adapting pipe 1 and the second adapting pipe 2 are connected through a transition pipe 3, and the axes of the first adapting pipe 1 and the second adapting pipe 2 are not overlapped to connect two eccentric risers.

An annular groove 12 is formed in the inner wall of the first adapting pipe 1, so that a sealing element can be placed to realize sealing connection with the stand pipe, and the connection sealing performance of the first adapting pipe 1 and the stand pipe is enhanced.

It will be appreciated that the offset distance of the axes of the first and

second adapters

1, 2 is determined by the eccentricity of the actual riser.

In one embodiment, a first limiting boss 13 is arranged at one end of the interior of the first adapting pipe 1, which is close to the transition pipe 3, so as to limit a riser connected to the interior of the first adapting pipe 1, and facilitate positioning and installation of the riser.

In one embodiment, a second limiting boss 21 is disposed at one end of the inside of the second adapting pipe 2 close to the transition pipe 3, so as to limit the vertical pipe connected inside the second adapting pipe 2 and facilitate positioning and installation of the vertical pipe.

In one embodiment, the outer wall of the second faucet pipe 2 is provided with anti-slip grooves 22 to prevent slipping during installation.

In one embodiment, the first adapting pipe 1 is provided with an annular convex part 11, and the inner wall of the annular convex part 11 is provided with the annular groove 12. Through the setting of annular bellying 11, can play outside skid-proof effect on the one hand, on the other hand has increased sealed space, and more does benefit to and promotes sealing connection reliability.

Referring to fig. 3, the method for using the eccentric connection device of the present embodiment is as follows: the first riser 4 is sleeved with the sealing element 6, the first bearing pipe 1 is sleeved on the first riser 4, the sealing element 6 is clamped in the annular groove 12 in the first bearing pipe 1, and the second bearing pipe 2 is sleeved on the second riser 5 and fixed by bonding. The sealing member 6 may be a rubber sealing member.

The eccentric connecting device is fixedly connected with the first vertical pipe 4 in a sealing way and fixedly bonded with the second vertical pipe 5, the operation is simple, the connection reliability is high, and the upper part can be effectively prevented from being seeped into the vertical pipe.

Through the eccentric connecting device, the first vertical pipe 4 and the second vertical pipe 5 which are eccentric can be effectively butted, and the normal construction is ensured.
