Otherwise, the interior section of so-called rigidity interpolation pipe or the inner, refer to that rigidity interpolation pipe is near that section or that one end of storing up water container intracavity. Equally, the outer section of rigid joint body, also refers to rigid joint body that section away from storage water container intracavity, and rigid joint body exposes at storage water container exterior.
Owing to the cap internal surface of nut cap is formed with tapering, so the intracavity diameter of nut cap is at the reduced diameter at this tapering position. The tapering position necking down end of so-called nut cap, refers to one end that in this tapering position of nut cap, diameter is less.
In so-called C font elasticity, the interior edge of button, refers to the edge near its center.
The present invention has the following advantages and effect:
One, the fast access node structure of tradition depends on the axle pressure to rubber cradle and realizes water-lute, and the present invention relies on the radial binding force of rigidity interpolation pipe to realize, and then brings following advantage and effect:
