Abstract

The invention provides a self-locking bottle plug capable of releasing steam air pressure and relates to a bottle plug for a thermos bottle. An inner ring 8 of a rubber cylinder 15 is sleeved on an annular groove 21 of the inner column body 9, and a cavity 23 of the rubber cylinder 15 wraps the inner column body 9, a V-shaped annular concave 22 of the inner column body 9 corresponds to an annular protruding strip 10 of the rubber cylinder 15, an air chamber 12 is formed between the V-shaped annular concave 22 of the inner column body 9 and a rubber cylinder 15, a hole 17 of the rubber cylinder 15 corresponds to the lower end of an air drain 14 of the inner column body 9. The annular protruding strip arranged in the self-locking bottle plug capable of releasing steam air pressure can form a close connection with a bottle container port, so that the self-locking bottle plug capable of releasing steam air pressure can be ensured not to separate from the thermos bottle port due to the high pressure in the bottle container. The self-locking bottle plug capable of releasing steam air pressure further has a function of automatically releasing pressure when pressure in a bottle container is too high, consequently, the bottle container can be ensured not to explode.

Description

But a kind of Self-locking cork of released vapour gaseous tension

[technical field]

The present invention relates to a kind of cork for thermos bottle, but especially relate to a kind of Self-locking cork of released vapour gaseous tension.

[background technology]

Known, vacuum bottle uses in a lot of families or unit office space as a kind of container of water temperature protection, and the hot water of packing into inside the glass liner of vacuum bottle is when pouring out some, form certain space in glass liner, the steam that expands in this time space can make wooden bottle stopper takeoff; At this moment the pressure in glass liner is greater than barometric pressure, so bottle stopper is kept out the pressure of hot air in bottle incessantly, causes bottle stopper to takeoff to make the hot water down quench in glass liner; The bottle stopper of commercially available vacuum bottle is vegetable cork, big up and small down taper shape, the bottleneck position of thermos refill is circular, making the bottleneck of vacuum bottle is that line contacts with the contact surface of bottle stopper, the bottleneck of some relatively poor thermos refill of doing manual work is non-circular structure, do not have especially insulation effect during heat air pressure in being subject to bottle, when using the bottle stopper of vegetable cork, need to firmly press down, in order to make the bottle stopper distortion form the structure of mating with bottleneck, in case " slight crack occurs sometimes " when at this moment glass liner exists became uneven even, just can cause the glass liner bottle explosion.

[summary of the invention]

In order to overcome the deficiency in background technology, but the invention discloses a kind of Self-locking cork of released vapour gaseous tension, the present invention can form with bottle bag edge by the annular protrusion bar that arranges and be connected comparatively closely, guaranteed that the present invention can not break away from because of the high pressure in glass liner the vacuum bottle bottleneck, releasing pressure automatically function when the present invention also has hypertonia in glass liner has guaranteed that glass liner bottle explosion can not occur.

In order to realize described goal of the invention, the present invention takes following technical scheme;

But a kind of Self-locking cork of released vapour gaseous tension, comprise rubber tube, inner cylinder, spheroid, spring and external thread column, the inner face suitable for reading of described rubber tube is provided with interior ring, be provided with at the outer edge surface of rubber tube middle part a plurality of around the annular protrusion bar, the middle part, lower end of rubber tube is provided with the hole; Described inner cylinder top is provided with baffle ring, the place is provided with endless groove at close baffle ring, be provided with air flue by the upper end to inner cylinder in the middle part of the lower surface of inner cylinder, be provided with at air flue middle part and connect the inner cylinder middle part around the pore that V-ring shape depression is set, described air flue top is extension diameter section, the air flue of the corresponding extension diameter section of spheroid bottom, and the two ends up and down of spring withstand on respectively on external thread column, spheroid, external thread column connects the negative thread on extension diameter section top, is provided with the relief hole of up/down perforation on external thread column; The inner ring sleeve of rubber tube is on the endless groove of inner cylinder, the described inner cylinder of cavity parcel of rubber tube, the annular protrusion bar of the corresponding rubber tube of V-ring shape depression of inner cylinder forms air chamber between the V-ring shape depression of inner cylinder and rubber tube, the air flue lower end of the corresponding inner cylinder in the hole of described rubber tube.

But the Self-locking cork of described released vapour gaseous tension is provided with the cylindricality handle on the baffle ring top on inner cylinder top, and cylindricality handle upper end outer edge surface is provided with annular protrusion.

But the Self-locking cork of described released vapour gaseous tension, the air flue lower port of described inner cylinder are provided with upwards depression.

But the Self-locking cork of described released vapour gaseous tension is provided with the in-line groove of screwdriver loading and unloading use in the upper side of external thread column.
