Abstract
The utility model relates to an air bag used for overflowing the water in air pressure method with various water bottles, which is composed of a push press column, a push press plate, a rubber cup, a pedestal, a restoring spring, etc. The leather cup is fastened on the pedestal in reversal, the push press column and the push press plate are connected into the integration, and the push press plate is attached with the upper surface of the leather cup. The restoring spring is sheathed on a central shaft in the push press column, the leather cup forms a curved face cavity, and the lower end is provided with an opening. When the air bag is pressed, each point has the deformation, and the utility model has the advantages of easy press, difficult damage and long service life.
Description
The utility model is a kind of air bag that is used for the water outlet of various water bottle air pressure.
The air pressure of use discharging device is all arranged in various vacuum flasks, its primary structure is to be provided with one by dish on the bottle top, by under the dish air bag being set, to press downwards by dish, bag volume diminishes, a part of gas in the air bag is discharged in bottle chamber, bottle cavity pressure is increased, water can be depressed into delivery port from the bottle chamber and discharge, the air bag that uses in various vacuum flasks at present all adopts the same collapsible air bag of similar accordion bellows basically, by pushing by dish, air bag length is reduced, thereby realize the purpose that bag volume diminishes, be compressed easily, do thinlyyer in burst for making this kind air bag, and deformation mainly concentrates on burst, therefore extruding repeatedly in burst breakage easily, has influenced the service life of air bag.
The purpose of this utility model provides a kind of extruding, cracky not, Air bag for thermos of long service life of being easy to.
The utility model is made up of parts such as pushing post, push plate, leather cup, base and back-moving springs, leather cup tips upside down on the base, and pushing post and push plate are connected as a single entity, and push plate is pasted mutually with the leather cup upper surface, be nested with back-moving spring on the central shaft in the pushing post, leather cup is the curved surface cavity.
The utility model all has deformation everywhere owing to adopt curved surface cavity leather cup structure when being squeezed, therefore needn't make some position do thinlyyer, is easy to extruding, also cracky not, and service life is longer.
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model leather cup structural representation.
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in drawings, the utility model is by pushing post (3), push plate (4), leather cup (1), base (6) and back-moving spring (5) are formed, pushing post (3) and push plate (4) are connected as a single entity, push plate (4) is pasted mutually with leather cup (1) upper surface, back-moving spring (5) is nested with on the central shaft in pushing post (3), leather cup (1) is down basin-like body, its top has a hole (2), the edge of perforate (2) is fixed in the flange (7) of pushing post (3), and leather cup (1) lower end ring edge is fixed in the draw-in groove at base (6) edge, when the needs water outlet, press the vacuum flask top by dish, pushing post (3) drives push plate (4) pressed home spring (5) and leather cup (1) downwards, makes leather cup (1) deformation, and volume diminishes, and then bottle cavity pressure is raise, water in the bottle chamber is extruded from delivery port, and one looses one's grip, and back-moving spring (5) resets pushing post (3) drive push plate (4), the utility model restores to the original state, push by dish again, but water outlet is again used so repeatedly.
The utility model can be widely used on the various Air pots.
Claims (3)
1, a kind of Air bag for thermos, form by pushing post (3), push plate (4), leather cup (1), base (6) and back-moving spring (5), pushing post (3) and push plate (4) are connected as a single entity, push plate (4) is pasted mutually with leather cup (1) upper surface, back-moving spring (5) is nested with on the central shaft in pushing post (3), it is characterized in that leather cup (1) is the curved surface cavity, tips upside down on the base (6).
2, Air bag for thermos as claimed in claim 1 is characterized in that the curved surface cavity of described leather cup (1) is basin-like body.
