  • Tube receiver assembled and detached rapidly
    Patent number: 6540169
    Abstract: A tube receiver has a winding disk and a body. The winding disk is extended with a shaft which is capable of being engaged to the body. Therefore, the winding disk pivotally rotates along the body. The shaft has an annular buckling groove at an end passing through the body. A slidable buckle installed at the body is configured with respect to the buckling groove of the shaft. The buckle has a flange. The flange is engaged to the buckling groove of the shaft for confining the axial position of the shaft. As the flange of the buckle separates from the buckling groove of the shaft, the winding disk will separate from the body.

  • Tube winder structure
    Patent number: 6457669
    Abstract: A tube winder structure including a seat body and a reel. The seat body has a stand, a handle and a shaft. The reel is rotatably fitted on the shaft of the seat body. The handle of the seat body has a tube-squeezing unit composed of the handle and a rod member parallel to the handle. A gap-adjusting mechanism is connected between the handle and the rod member for adjusting the gap between the handle and the rod member. During winding of the tube, the tube-squeezing unit is able to drain the water from the flat tube and simultaneously flatten the flat tube so as to reduce the volume thereof, whereby the flattened flat tube can be smoothly wound and collected on the reel.
