Abstract: The present invention discloses an extensible flexible hose comprise one elastic inner layer, one elastic textile reinforcement layer and one elastic outer layer, where the elastic textile reinforcement layer placed on the outer surface of the elastic inner layer, the elastic outer layer disposed on the elastic textile reinforcement layer, while the elastic inner layer and the elastic textile reinforcement layer are reciprocally coupled, the elastic outer layer and the uncovered surface area of the elastic inner layer are reciprocally joined to form a unitary tubular member. The elastic textile reinforcement layer comprising a twill weave textile layer, with stretch yarns longitudinally distributed among. The objective of the present invention is to improve the phenomenon that the telescopic water pipe is liable to be damaged due to strong friction between inner core and outer sheath, to prolong the service life of the extensible flexible hose.

Abstract: A four-layer-structured water passing device is provided, in which a first sleeve and a second sleeve are disposed between an elastic inner tube and an outer cloth sheath. When the water passing device is connected with a pressurized water source, the first sleeve can quickly eliminate or reduce the impact wave strength when receiving a strong expansion impact from the elastic inner tube, such that the first sleeve can gently transmit the fluctuation to the second sleeve, and the second sleeve extends the outer cloth sheath to the limit length, so as to avoid damage caused by frequent direct contact friction between the elastic inner tube and the outer cloth sheath. The water passing device is also configured to avoid permanent deformation and abrasion at the joint position between the elastic inner tube and the outer cloth sheath, and thus prolong the service life of the water passing device.
