According to the utility model, the first eccentric pipe and the second eccentric pipe are connected by adopting the connecting piece, so that the problem of difficult installation caused by distance and center deviation of the embedded pipeline can be solved, and meanwhile, the structure is axially movable, so that the shock absorption and the stress caused by thermal expansion and cold contraction can be realized.

Description

Adjustable connecting pipe

Technical Field

The utility model relates to the technical field of connecting pipes, in particular to an adjustable connecting pipe.

Background

Pipes are devices for transporting gas, liquid or fluid with solid particles, which are coupled by pipes, pipe couplings, valves, etc.

In practical situations, when two pipes are connected, the two pipes cannot be moved or the angle of the two pipes cannot be adjusted, if the angle of the two pipes needs to be changed, the two pipes or the connecting device of the two pipes must be changed, so that the operation steps of the staff are increased, and the working efficiency of the staff is reduced.

In view of the above, the present utility model provides an adjustable coupling tube that is axially movable.

Disclosure of utility model

The utility model provides an adjustable connecting pipe capable of moving axially.

The utility model aims to provide an adjustable connecting pipe which comprises a first eccentric pipe, a second eccentric pipe, a movable flange and a connecting piece, wherein the first eccentric pipe and the second eccentric pipe are connected through the connecting piece, the connecting piece comprises an inner hexagon screw, a middle pipe and a compression ring, the movable flange is arranged at the end parts of the first eccentric pipe and the second eccentric pipe, the connecting part of the first eccentric pipe and the second eccentric pipe is arranged in the middle pipe, the compression ring is arranged at the two ends of the middle pipe, and the inner hexagon screw is fastened at the two ends of the middle pipe.

Further, the first eccentric tube and the second eccentric tube can be axially adjusted by +/-10 mm, and the first eccentric tube and the second eccentric tube can be radially adjusted by 0-20 mm.

The utility model has the following advantages: according to the utility model, the first eccentric pipe and the second eccentric pipe are connected by adopting the connecting piece, so that the problem of difficult installation caused by distance and center deviation of the embedded pipeline can be solved, and meanwhile, the structure is axially movable, so that the shock absorption and the stress caused by thermal expansion and cold contraction can be realized. According to the utility model, through the arrangement of the compression ring, a limiting effect can be effectively achieved on the first eccentric pipe and the second eccentric pipe, and the first eccentric pipe and the second eccentric pipe are prevented from falling off.

Detailed Description

The utility model provides an adjustable connecting pipe which comprises a first eccentric pipe 3, a second eccentric pipe 4, a movable flange 1 and a connecting piece, wherein the first eccentric pipe 3 and the second eccentric pipe 4 are connected through the connecting piece, the connecting piece comprises an inner hexagonal screw 6, an intermediate pipe 5 and a compression ring 2, the movable flange 1 is arranged at the end parts of the first eccentric pipe 3 and the second eccentric pipe 4, the connecting parts of the first eccentric pipe 3 and the second eccentric pipe 4 are both positioned in the intermediate pipe 5, the compression ring 2 is arranged at the two ends of the intermediate pipe, and the inner hexagonal screw 6 is fastened at the two ends of the intermediate pipe 5.

In the embodiment, the first eccentric tube and the second eccentric tube can be axially adjusted by +/-10 mm, and the first eccentric tube and the second eccentric tube can be radially adjusted by 0-20 mm.

In this embodiment, through the setting of clamping ring 2, can effectively play a limited effect to first eccentric pipe 3 and second eccentric pipe 4, prevent that first eccentric pipe 3 and second eccentric pipe 4 from dropping.

In this embodiment, the first eccentric pipe 3 and the second eccentric pipe 4 adopt the mode of connecting the connecting piece, can design axial and radial adjustment volume as required, can solve the installation difficulty that causes because of distance and central deviation with pre-buried pipeline, and the axial is movable simultaneously, plays the shock attenuation and prevents the stress that expend with heat and contract with cold to cause.

In this embodiment, the first eccentric pipe 3 and the second eccentric pipe 4 are axially adjustable by ±10mm, and the movable flange 1 is placed in a concentric state by this arrangement.

In the embodiment, the first eccentric tube 3 and the second eccentric tube 4 relatively rotate for 0-180 degrees and radially move for 0-20 mm, so that stepless adjustment of 0-20 mm can be realized.

Although specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, it should not be construed as limiting the scope of protection of the present patent. Various modifications and variations which may be made by those skilled in the art without the creative effort are within the scope of the patent described in the claims.
