A quickconnect structure having a fitting connector, a connector, and U-shaped positioning snap pin. The fitting connector has a connector part, a fitting connector body part coupled to the connector part, and a fitting part coupled to the fitting connector. The connector part, the fitting connector body part, and the fitting part define a fitting hole extending therethrough, and the fitting part defines positioning groove, a longitudinal snap hole, and a side snap opening in communication with the longitudinal snap hole. The connector has a connection end, a connector body part coupled to the connection end, and a positioning bump. The connection end and the connector body part define a duct hole extending therethrough, the connection end defines a positioning snap groove, and the fitting connector is configured to accept the connection end in the fitting hole. When the connection end is fully inserted into the fitting connector, the positioning bump is located in the positioning groove, and the longitudinal snap hole is aligned with the positioning snap groove. The U-shaped positioning snap pin has a pin base, a pin body part coupled to the pin base, and a snap protrusion coupled to the pin body part. The U-shaped positioning snap pin is configured to be partially inserted and fully inserted into the longitudinal snap hole; when partially interested, the snap protrusion engages the side snap opening and the connector is able to be inserted into the fitting connector; and when fully inserted and when the connector is inserted into the fitting connector, the pin body part engages the positioning snap groove and the snap protrusion engages a longitudinal snap hole exit.

A quick connector structure includes a fitting connector, a connector, and a U-shaped positioning snap pin. The fitting connector is a pipe connector, a three-way valve connector, or a washing machine valve connector. The fitting connector is combined with a pipe body. The U-shaped positioning snap pin ensures the stability of the connection between the fitting connector and the connector. The quick connector structure enables rapid positioning and assembly, reducing the assembly difficulty in a smaller or concealed space and achieving the effects of assembly stability and convenience.

A valve structure with an elastic anti-leakage member includes a spool, a seat, and a switch. The spool body has at least one inner notch formed on the side of the spool body, and the inner notch has at least one elastic anti-leakage member installed in the inner notch. The spool is contained inside the seat, and the elastic anti-leakage member is located in the inner chamber of the inner notch and has a surface elastically abutting the internal cavity wall of the inner chamber.

A valve structure with an elastic anti-leakage member includes a spool, a seat, and a switch. The spool body has at least one inner notch formed on a side of the spool body, and the inner notch has at least one elastic anti-leakage member installed in the inner notch, and the seat has an inner chamber with an internal cavity wall. The spool is contained in an inner of the seat, and the elastic anti-leakage member installed in the inner chamber of the inner notch of the spool body has a surface elastically abutting against the internal cavity wall of the inner chamber of the seat to achieve a good water anti-leakage effect.

A compressive heat-resistant tube structure for RV includes a compressive heat-resistant multi-layer tube. The compressive heat-resistant multi-layer tube includes a compressive heat-resistant PVC soft inner tube, a polyester dense crocheted covering layer, and a compressive PVC soft outer tube. An outer surface of the compressive PVC soft outer tube is provided with an identification surface layer portion. The identification surface layer portion enables the user to easily and quickly identify each tube for connection of tubes. The soft compressive heat-resistant multi-layer tube can be bent according to the demand of use, not limited to the arrangement of the edge wiring. The soft compressive heat-resistant multi-layer tube is convenient for use and can be installed conveniently.
