The present invention relates to a double-structure hose and a terminal device thereof. The invention comprises an external hose (102) and an internal hose (104) positioned therein. At least one supporting baffle plate (106) is arranged between the internal hose (104) and the external hose (102). Therefore, a transfer passage (A) is formed through the internal hose (104) and a transfer passage (B) is formed between the internal hose (104) and the external hose (102), thereby transferring different fluids or gases by separating the fluids or the gases from each other. In addition, a terminal device (200) connected with the external hose (102) and the internal hose (104) is provided. The terminal device (200) comprises a cylindrical body (210), wherein the body (210) is combined with a 1st cover unit (220) for coupling one end of the body (210) with the external hose (102) and a 2nd cover unit (230) for being coupled with the other end of the body (210) and receiving a drawing unit (234). The drawing unit (234) is equipped with a drawing shaft (234b) of which one end is connected to the internal hose (104) and the other end is connected to an internal hose nipple (236) so that fluids or gases transferred through the transfer passage (A) can be transferred. Furthermore, the body (210) comprises an external hose nipple (240) to supply the fluids or the gases transferred through the transfer passage (B) to the outside by forming a mounting hole (216) on the body. According to the present invention, a hose tangle is prevented during work, and consequently the invention has the benefits of improving working efficiency and easily drawing different fluids or gases by separating the fluids or the gases from each other. |
