A side opening 6, snorkel 1, side opening 6 and strutting communicate inside air bag 2.
As illustrated in figs. 2-7, charge valve 4 includes the pressing body for having elastic-restoring force by a pedestal 10, diaphragm 20 and one
30 are formed.Wherein, pedestal 10 is in a discoid body, and with made by the hard material of TPU plastics, its top surface centre of pedestal 10 is equipped with
One tube socket 11,11 top surface of tube socket are equipped with the wavy surface 12 of concave-convex surface, then have a through-hole 13 in tube socket 11,13 root edge of through-hole is set
There is the chamfering 14 in arc-shaped, and be equipped with most branch fins 15 in its outboard peripheries, in addition, 11 periphery of tube socket of 10 top surface of pedestal
Place is further provided with a bulge loop 16.
Diaphragm 20 is made of PU material, is set at the bottom surface of the through-hole 13 of above-mentioned pedestal 10, and in greater than outside through-hole 13
Multiple holes 21 are equipped at diameter, 20 outer peripheral edge of diaphragm is pressed by high frequency or molding processing technology and pedestal 10, so i.e.
So that each hole 21 of diaphragm 20 it is corresponding be set to through-hole 13 periphery at, i.e., so that combined between diaphragm 20 and pedestal 10 with
Form the structure of a check valve.
Pressing body 30 is set to 10 top of pedestal, and the inside of pressing body 30 has gas chamber 31, and the top of gas chamber 31, which is equipped with, wears
Hole 32, bottom outside periphery are then equipped with sealing edge 33, by the corresponding pressing of sealing edge 33 or pedestal 10 are bonding on, so that its shape
At the charge valve 4 of a tool gas chamber 31.In addition, the also settable check valve at perforation 32.
Detailed description below plain type charge valve 4 of the invention is formed after being combined with air bag 40 with the work of cushioning cells 2
Principle:
As illustrated in figures 4-5, in use, when bringing pressure to bear on the pressing body 30 of charge valve 4, inside the gas chamber 31 of pressing body 30
Air be squeezed and be discharged towards the through-hole of pedestal 10 13, and the diaphragm 20 of 13 bottom of through-hole will be by discharge gas pressure
The fine crack for squeezing and generating, air can then enter in air bag 3 via each hole 21 of diaphragm 20 at this time, then through snorkel
1 into strutting in air bag 2, makes to strut the expansion of air bag 2.
As shown in fig. 6-7, and when the pressure for imposing on pressing body 30 discharges, which can then generate an elastic recovery
Power, air then can by the perforation 32 at top enter gas chamber 31 in fills, at this time 13 bottom of through-hole PU diaphragm 20 will simultaneously by
The pressure of gas acts on and is tightly attached to through-hole 13 upwards in the suction function and air bag 3 of gas chamber 31, due to 20 material of diaphragm
Characteristic and have toughness so that diaphragm 20 forms a cancave cambered surface at through-hole 13, and closely pasted completely with 31 periphery of through-hole
It closes, the check effect of gas is reached with this, and then form the structure design of a check valve, squeezing action is repeatedly to complete to support
Open the filling of 2 air of air bag.
As shown in figure 8, vent valve 5 includes valve body 51, flap 56, valve rod 52, spring 53 and pressing component 54,51 bottom of valve body
Face is equipped with valve port 57, the inside of valve port 57 with communicated inside air bag 3；Spring cavity is equipped at the top of valve body 51, spring cavity is opened on
51 top surface of valve body, pilot hole 55 is equipped in valve rod 52 vertically, and valve rod 52 is set in pilot hole 55 vertically and can be relative to valve body 51
It moves up and down, 52 lower end of valve rod is connect with flap 56, and 52 upper end of valve rod is connect with pressing component 54, and 53 sets of spring in valve rod 52
On, 53 bottom end of spring is withstood on the inner wall of spring cavity, and 53 upper end of spring is withstood on pressing component 54, and pressing component 54 is cylinder
Shape, the outer diameter of pressing component 54 are less than the internal diameter of spring cavity, and flap 56 and the sealing of valve port 57 cooperate under the action of spring 53.Its
In, flap 56 be it is round table-like, valve port 57 is the truncated cone-shaped cavity being adapted to flap 56.
When needing to deflate, pressing component 54 is pinned downwards, and flap 56 is made inwardly to be detached from valve port 57, air bag 3 and support
The gas opened in air bag 2 is successively discharged through valve port 57, pilot hole 55 and spring cavity.When external force disappears, in the promotion pressing of spring 53
Component 54 and valve rod 52 move up, and return to flap 56 in valve port 57 and reseal cooperation with valve port 57.It certainly can also
Exhaust outlet is set on air bag 3, removes plug when needing to deflate in exhaust ports setting plug.
The utility model inflation/deflation is easy to operate, easy to use, struts air bag in the operation of hysteroscope posterior peritoneum after inflation
It can play the role of strutting, form space in order to avoid injury tissue and blood vessel.
Certainly, the utility model can also have other numerous embodiments, without departing substantially from the spirit of the present invention and its essence
