Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
A kind of pneumatic dust blower sealing device as shown in Figure 1, including gun body 1 include an air inlet 11 in the gun body 1
And a gas outlet 12, further include having fixed seat 2, plug 3 and push rod 4, a connecting cavity 13, institute are provided in the gun body 1
It states and is provided with a seam allowance step in connecting cavity 13,2 screw thread of the fixed seat is rotatably connected in connecting cavity 13 and is provided in its bottom
The male half coupling 21 being connect with seam allowance step, one is provided at the male half coupling 21 can be with seam allowance step at the first close of sealing
Seal 5, the fixed seat 2 are axially and radially respectively arranged with a movable span 22 and a venthole 23, the venthole along it
23 are connected to 22 middle part cross of movable span, the air inlet 11 connect connecting cavity 13 simultaneously be connected to 22 end of movable span, it is described go out
Gas port 12 connects connecting cavity 13 and simultaneously be connected to venthole 23, and the push rod 4 is front and back interior and being capable of edge through movable span 22 is connected to
Its length direction pulls and pushes activity, and the plug 3, which is screwed on, to be fixed on the end of push rod 4 and be provided in plug 3 and 4 junction of push rod
Can form the second sealing ring 6 of sealing with 2 distal end faces of fixed seat, the top of the fixed seat 2 stretch out in connecting cavity 13 and
It is screwed with nut set 7 on the outside, the nut covers 7 bottoms and 1 junction of gun body is provided with third sealing ring 8, the spiral shell
7 inside of mother set is provided with the 4th sealing ring 9 with 4 junction of push rod.
Wherein, the top of the connecting cavity 13 is provided with a counter sink and is provided with a compression spring 10 in counter sink, described
A male half coupling step pressed on compression spring 10 is provided on push rod 4;The oral area of the connecting cavity 13 is provided with can be with fixation
The internal screw thread that seat 2 is screwed on.
Air inlet 11 is connected gas circuit by a kind of pneumatic dust blower sealing device that the present invention mentions when specifically used
Hose opens the master switch being located in gun body 1, when original state, since the compression spring 10 in fixed seat 2 plays push rod 4
