Abstract

The present invention relates to a structural improvement of a drain pipe, which mainly consists of a flexible pipe member combined with a spiral loop at the outer periphery thereof and the interior thereof is in a smooth state, adjacent loops and two ends of the pipe member are respectively installed with a connector for being connected with a water related equipment and a water draining hole of a water draining pipeline, thereby achieving an excellent connection relation by utilizing the two connectors at two ends of the pipe member to connect the water related equipment and the water draining hole of the water draining pipeline, the configuration of the pipe member can be properly bent and adjusted according to the installation space thereby obtaining a smooth water draining effect, and after the pipe member is bent and set, the smoothness of the inner pipe wall can be kept.

Claims

1. A structural improvement of a drain pipe, used for connecting a water draining joint of a water related equipment and a water draining hole of a water draining pipeline, the drain pipe includes:

a pipe member tailored to a predetermined length according to the requirement, and made of a material having the flexible property;

during the formation of the pipe member, the outer periphery of the pipe member is integrally combined with a spiral loop, thereby providing features of bendable and settable, wherein the inner pipe wall of the pipe member is in a smooth state;

a connector installed at one end of the pipe member for being mated and connected with the water draining joint of the water related equipment;

another connector installed at the other end of the pipe member for being mated and connected with the water draining hole of the water draining pipeline.

2. The structural improvement of the drain pipe as claimed in claim 1, wherein the spiral loop combined at the outer periphery of the pipe member is made of metal.

3. The structural improvement of the drain pipe as claimed in claim 1, wherein on the spiral loop combined on the outer periphery of the pipe member, adjacent loops are spaced with a predetermined interval.

4. The structural improvement of the drain pipe as claimed in claim 1, wherein the pipe member and the connectors at two ends are integrally formed during the molding of the connectors.

5. The structural improvement of the drain pipe as claimed in claim 1, wherein the connector at one end of the pipe member is formed as a predetermined bent pipe configuration, so a drain pipe arrangement formed by two or more than two pipe members is enabled to be achieved according to the space limitation.
