Among the figure, the 1-adapter body; 11-the first cavity; The 111-card convex; 12-the second cavity; The 13-worm structure; The 14-projection; The 2-one-way valve; The 21-gasket seal; 22-seals steel ball; The 23-spring; The 3-control structure; The 31-push rod; The 32-top.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.
Charging joint comprises the adapter body that is provided with inner chamber and both ends open, the one-way valve that control flow on-off is opened and the control structure of controlling these one-way valve closure or openness, and this one-way valve and this control structure are installed in the inner chamber.
The present embodiment charging joint as depicted in figs. 1 and 2, comprise the adapter body 1 that is provided with inner chamber and both ends open, the one-way valve 2 that control flow on-off is opened and the control structure 3 of controlling these one-way valve 2 closure or openness, this one-way valve 2 and this control structure 3 are installed in the inner chamber.Adapter body 1 is the cylindrical structure of hollow.
Inner chamber comprises the first cavity 11 that control structure 3 is installed; Control structure 3 comprises the push rod 31 and the top 32 that is connected with this push rod 31 that is flexibly connected with one-way valve 2, and this comes directly towards 32 parts and is located at adapter body 1 outside, and push rod 31 is mobile with control one-way valve 2 closure or openness in the first cavity 11.
Inner chamber also comprises the second cavity 12 of one-way valve 2 being installed and being communicated with the first cavity 11, and this one-way valve 2 comprises that to be located at the second cavity 12 inner and near the gasket seal 21 of the first cavity 11, cooperate to control the spring 23 of the sealing steel ball 22 that the flow on-off opens and a reset response that is connected with sealing steel ball 22 with sealing pad 21.Push rod 31 is flexibly connected to control sealing steel ball 22 with sealing steel ball 22 to be connected or to separate with gasket seal 23.When sealing steel ball 22 was connected with gasket seal 23, one-way valve 2 was opened, the fluid circulation; When sealing steel ball 22 separates with gasket seal 23, one-way valve 2 closures, fluid disconnects.
The outer wall of the second cavity 12 be provided with for the worm structure 13 that fills flexible pipe or gas collecting tube and be connected.
