One end is located at the intracavitary that the second cavity wall 1112 surrounds；When slide bar is moved to the spacing shoulder 1113 of projection contacts, spacing shoulder
1113 stop slide bars continue to move to.Stop the projection on slide bar using spacing shoulder 1113, such design structure is simple, operation side
Just.
It should be noted that the spacing design when projection on above-mentioned slide bar can also push single current part open as slide bar, i.e.,
When the valve element in single current part is opened on slide bar top, on slide bar projection contacted with the exit end face of single current part, stop slide bar after
Continue and moved into single current part.
As shown in figure 4, spacing design when pushing single current part open for slide bar：Tapped blind hole is provided with the side wall of slide bar
141, tapped blind hole 141 is used to wear to connect stud 142, spiral shell between sliding part and the other end of slide bar, in tapped blind hole 141
Post 142 is used to, when slide bar is moved to stud 142 and contacts the other end of connection member 11, stop that slide bar continues to move to.In slide bar
When penetrating in the first inner chamber 111 of connection member 11, do not worn in the tapped blind hole 141 of slide bar and connect stud 142, worn and connect when slide bar
Afterwards, then by stud 142 it is threaded into blind hole 141, prevents slide bar from moving using the stud 142 of connection in tapped blind hole 141, if
Meter is simple, easy to operate.
Spacing design when slide bar is promoted and pulled back can be realized simultaneously：As shown in figure 5, position limiting structure 14 includes being arranged at cunning
The stopper slot 143 of part is moved, tapped through hole 113 is provided with the side wall of connection member 11, is used to wear in tapped through hole 113 to connect spiral shell
Silk 114, so that in the end insertion stopper slot 143 of screw 114, when slide bar is moved to the side wall of the contact stopper slot 143 of screw 114
When, stop that slide bar continues to move to.When slide bar is penetrated in the first inner chamber 111 of connection member 11, in the side wall of connection member 11
Do not worn in tapped through hole 113 and connect screw 114, be threaded into after slide bar, which is worn, to be connected, then by screw 114 in through hole 113, screw
In 114 end insertion stopper slot 143, in movement, stopper slot 143 moves slide bar, when the side wall of stopper slot 143 is touched
During to screw 114, screw 114 stop slide bar continue to move to, in stopper slot 143 relative two side limit respectively slide bar promote and
Position when pulling back, structure design is simple, easy to operate.
Specifically, the first connector portions 112 are to be arranged at the internal thread of the one end of connection member 11, and internal thread is used for thread seal
It is connected to the port of export of single current part.It is simple and convenient by the way of threaded connection, it can also realize preferable sealed connection.
Specifically, the second connector portions 122 are to be arranged at the pagoda head of the inflation sliding other end of part 12, and pagoda head is used to connect
Connect the flexible pipe into source of the gas.Pagoda head, as its name suggests, the joint of shape such as pagoda, source gas line use flexible pipe, according to gas source pipe
The bore of line designs the size of pagoda head, and pagoda head connection flexible pipe is convenient, good airproof performance, pressure-bearing are high.
The gas-charging connection that the utility model embodiment provides, for connecting the single current part at cylinder outlet, it will connect
In the port of export connection procedure of part and single current part, keep inflating into gas-charging connection, so as to by the air in gas-charging connection
All discharges, after connection member connects with single current part, inflation sliding part is promoted its one end top is opened in single current part
Valve element, make to be filled with the gas in the second inner chamber of inflation sliding part and flow into single current part, and flow into gas cylinder, filled
Bi Hou, inflation sliding part is retracted, makes single current part reverts normal operating conditions, is then shut off source of the gas, pulls down gas-charging connection, this
When due to single current part one-way flow effect, air may not flow into gas cylinder, in above process, by gas-charging connection to
Inflated in gas cylinder, can be achieved to avoid air from entering in gas cylinder, improve the charging purity in gas cylinder；And aforesaid operations are simple just
Victory, realize the function of fast filling.
It is described above, only it is preferred embodiment of the present utility model, not the utility model is made any formal
