The further improvement is that: the elastic tube is a latex tube.

The further improvement is that: the anti-slip column is in threaded connection with the abutting plate.

The further improvement is that: the antiskid columns are arranged on the top abutting plate in a matrix array.

The further improvement is that: the plastic tube has a length greater than the sum of the lengths of the two elastic tubes.

After the technical scheme is adopted, the utility model discloses beneficial effect does: two flanges are connected respectively in the drain line, and the cooperation of plasticity pipe, elasticity pipe, strutting arrangement makes the expansion bend reduce the expansion bend vibration when the fluid passes through the expansion bend, and the condition that the junction leaked between greatly reduced expansion bend and the drain line need not to overhaul often, is favorable to the expansion bend to use.

Further effects are as follows: the latex tube enables the telescopic device to have elastic capacity.

fig. 2 is a schematic structural view of the middle plastic pipe and the bearing plate of the present invention.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 2, the technical solution adopted by the present embodiment is:

the utility model provides a drain line expansion bend, includes two flanges 1, sets up in two flexible pipe between the flange 1, flexible pipe is including setting up in two plasticity pipe 2, the connection between the flange 1 plasticity pipe 2 with the elasticity pipe 3 of flange 1, set up in be used for supporting with the ground cooperation on the plasticity pipe 2 the strutting arrangement of plasticity pipe 2 reduction expansion bend vibration when the fluid passes through the expansion bend.

The supporting device comprises a bearing plate 4 arranged on the plastic pipe 2 and used for bearing the plastic pipe 2, a damping layer 5 arranged on the end face, away from the plastic pipe 2, of the bearing plate 4, and a supporting plate 6 arranged on the end face, away from the bearing plate 4, of the damping layer 5 and used for supporting and matching with the ground.
