The specific embodiment

Introduce the specific embodiment of a kind of bottle stopper of the utility model below in conjunction with accompanying drawing, but it may be noted that the enforcement of the utility model is not limited to following embodiment.

Can know that with reference to figure 1 a kind of bottle stopper comprises main body 1, expansion loop seat 4, expansion loop 5, spring 3 and briquetting 2.Be provided with the cavity 6 and first through hole 10 in the main body 1, and first through hole 10 is connected with cavity 6.Briquetting 2 comprises cylinder 201 and lower prop 202 two parts, and is provided with a closed-loop 12 at cavity 6 opening parts of bottle stopper main body 1, and the inside radius of closed-loop 12 is greater than last cylinder 201 radiuses, and less than lower prop 202 radiuses; Briquetting 2 lower props 202 are positioned at cavity 6 upper ends, and closely contact with cavity 6 perisporiums, and cylinder 201 exposes outside bottle stopper on the briquetting 2; An end opening of second through hole, 7, the second through holes 7 that is provided with inverted "L" shaped in the briquetting 2 is at lower prop 202 lower walls, and other end opening is at briquetting 2 sidewalls.Expansion loop seat 4 upper ends clog cavity 6 lower ends, and closely contact with cavity 6 perisporiums, and expose below main body 1 lower end; Be provided with the third through-hole that is connected 8 and fourth hole 9 in the expansion loop seat 4, third through-hole 8 is axially extending bores, fourth hole 9 be with axial vertical direction on through hole, two exits of fourth hole 9 are surrounded by expansion loop 5 respectively; Said expansion loop 5 is a hollow hemisphere, is processed by rubber, and this spheroid opening part and fourth hole 9 exits are tightly connected.Spring 3 has two, all be located in the space that expansion loop seat 4 upper walls and lower prop 202 lower walls surround, and spring 3 two ends respectively with expansion loop seat 4 upper walls and lower prop 202 lower wall Joints.The axis of said cavity 6, briquetting 2, expansion loop seat 4 all is located along the same line.

The purpose that closed-loop 12 is set is the displacement in the axial direction of restriction briquetting 2; Avoid because steam air pressure increases sharply suddenly; When expansion loop 5 did not also have enough time to expand, the power that steam imposes on briquetting 2 had surpassed the power that spring 3 can bear, and makes that briquetting 2 is ejected.

During use, earlier bottle stopper is filled in bottleneck, spring 3 is in natural length, when the steam of heat gets in the bottle top, and in the space that can surround through third through-hole 8 entering bottle stopper main bodys 1, expansion loop seat 4, lower prop 202,

Become big owing to can hold the space of the steam of heat, the power that steam imposes on bottle stopper main body 1 can diminish, and makes that bottle stopper is not easy to be ejected; Simultaneously steam also can get in the space that expansion loops 5 and expansion loop seat 4 surround through fourth hole 9; Because expansion loop 5 has certain elasticity, can expand gradually, just be stuck in the position at bottleneck 11 places; Make bottle stopper can not ejected; And steam vapour amount is big more, and it is more severe that expansion loop 5 just expands, and that just blocks at bottleneck 11 places is tight more.

When needs are extracted bottle stopper, as long as depress the last cylinder 201 of briquetting 2 gently, when spring 3 is pressed onto minimum compressed length; Second through hole 7 is connected with first through hole 10, and the steam in the bottle can be discharged through second through hole 7 and first through hole 10, and expansion loop 5 does not have the pressure of steam; Also can be contracted to original state, as shown in Figure 2, because expansion loop 5 no longer blocks bottleneck 11; Unclamp briquetting 2 this moment, just can bottle stopper have been extracted gently.

The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
