Fig. 2 is the use schematic representation of the stopper of a kind of inflation/deflation one of the utility model.
Embodiment
Below in conjunction with accompanying drawing, further specify specific embodiment of the utility model.
As shown in Figure 1, the utility model provides a kind of stopper of inflation/deflation one, and this stopper comprises: air vent 1, inner core 2, inflation inlet plug 3.
Air vent 1 is rubber product, and it is arranged on the external inflated article, and the gas in the external inflated article inner chamber is discharged by this air vent 1.
Inner core 2 adopts the hard plastics to make, and this inner core 2 is used for being embedded at air vent 1, and the external diameter of inner core 2 and air vent 1 internal diameter are complementary, and are used for the sealing of assurance air vent 1, when inner core 2 is filled in the air vent 1, enters air vent 1 by bottom one end of inner core 2.
Inner core 2 tops are connected with air vent 1 by a connecting band, guarantee that when connecting band is crooked bottom end and the air vent 1 of inner core 2 is oppositely arranged.
This inner core 2 is provided with inflation inlet 21, and this inflation inlet 21 connects top and the two ends, bottom of inner core 2, and the external world is communicated with the inner chamber of inflated article.
Inner core 2 tip edge are provided with pull ring, and this pull ring is convenient to staff and is pinched, and are convenient to inner core 2 extracting from air vent 1.
Inflation inlet plug 3 adopts rubber product, and it is used for being embedded at the inflation inlet 21 on the inner core 2, and the internal diameter of inflation inlet 21 is complementary on the external diameter of this inflation inlet plug 3 and the inner core 2, when inflation inlet plug 3 is filled in inflation inlet 21, guarantees the sealing of inflation inlet 21 on the inner core 2.
The top of this inflation inlet plug 3 is connected with the top of inner core 2 by a connection strap, when this connects the connection strap bending of inner core 2 and inflation inlet plug 3, is oppositely arranged as inflation inlet 21 on the bottom of assurance inflation inlet plug 3 and the inner core 2.
The top of inflation inlet plug 3 is provided with extension piece 31, and extension piece 31 is provided with anti-skidding striped.This extension piece 31 is used for staff and pinches, and is convenient to inflation inlet plug 3 extracting from inflation inlet 21.
Be provided with one-way valve 4 in the inflation inlet 21 of inner core 2.The gas communication direction of this one-way valve 4 is served as reasons in the extraneous inner chamber that flows into external inflated article, thereby stops the outflow of gas in the external inflated article inner chamber when inflation.
This one-way valve 4 adopts resilient rubber product, and it comprises the expansion strip on diaphragm seal and vertical setting and the diaphragm seal.Be provided with the hollow out support in the inflation inlet 21 of inner core 2, this expansion strip is fixed on this hollow out support, is at one-way valve 4 diaphragm seal is attached on the hollow out support hermetically, makes inflation inlet 21 realize sealing.When inflated condition, the gas that is filled with inflation inlet 21 acts on the diaphragm seal, makes expansion strip stressed and stretch, thereby diaphragm seal is separated with the hollow out support, and gas then can enter in the external inflated article inner chamber by inflation inlet 21.
This stopper also comprises base 5, and it is connected with external inflated article is surperficial, and air vent 1 is arranged on this base 5.This base adopts rubber to make.
The working principle of the stopper of a kind of inflation/deflation one of the utility model is as follows:
As shown in Figure 2, normal being used under the state of seal operation, inner core 2 is embedded in the air vent 1, and inflation inlet plug 3 then is embedded in the inflation inlet 21 of inner core 2, realize the utility model inflation/deflation one stopper to the sealing between external inflated article inner chamber and the external world.
When inflating work, then inflation inlet plug 3 is extracted from the inflation inlet 21 of inner core 2, inflation inlet 21 connects external charger, external charger is to inflation inlet 21 inflations, the gas that is filled with acts on the diaphragm seal of one-way valve 4, the expansion strip of one-way valve 4 stretches, and makes diaphragm seal break away from the hollow out support of inflation inlet 21, and then gas can smooth and easyly enter in the inner chamber of inflated article.
When inflation stopped, the diaphragm seal of one-way valve 4 was not subject to not having blast simultaneously, and then the expansion strip of one-way valve 4 shrinks, diaphragm seal rebounds fast, the diaphragm seal of one-way valve 4 closely is attached on the hollow out support of inflation inlet 21, makes inflation inlet 21 sealings, realize the non-return effect of one-way valve 4.Again inflation inlet plug 3 is filled in the inflation inlet 21, namely guaranteed the fully sealing of inflation inlet 21.
When inflated article is exitted, then inner core 2 is extracted from air vent 1, realize that then the gas in the inflated article inner chamber is discharged smoothly.
Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple modification of the present utility model with to substitute all will be apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
