Abstract

The utility model discloses a heat-insulating bottle plug. The structure is as follows: a hole penetrating up and down is formed at the middle of a plug body; a ventilation channel is arranged at the lower end of the hole, and an air overflow channel is arranged at the upper end of the hole; a notch is formed on the air overflow channel; the circular centres of the ventilation channel, the air overflow channel and the notch are located on the same central axis; a plug head is arranged in the ventilation channel; the plug head is conical on the whole, and the upper end of the plug head penetrates through the air overflow channel via a connection rod and is fixedly connected with a button which is arranged in the notch; a tension spring is sleeved on the connection rod, the lower end of the tension spring is fixedly connected with the plug head, and the upper end of the tension spring is fixed on the sidewall of the air overflow channel; an inclined conical surface fitting the plug head is arranged between the ventilation channel and the air overflow channel; and in the case that the tension spring applies tension on the plug head, the plug head can be automatically plugged on the inclined conical surface between the ventilation channel and the air overflow channel. The heat-insulating bottle plug disclosed by the utility model is simple in structure and ingenious in conception; and because the plug head is under the action of the tension spring, the air pressure in a bottle is always equivalent to the air pressure outside the bottle.

Description

A kind of plug for vacuum bottle

Technical field

The utility model relates to the daily life tools field, is specifically related to a kind of plug for vacuum bottle.

Background technology

In the process of routine use thermos bottle; usually the phenomenon that bottle stopper can pull out out can appear; if extract by force; the careless slightly interior hot water of water bottle that will make spills; thereby cause the phenomenon of scalding; this be since at present common bottle stopper mostly be greatly wooden entity structure manufacturing and form, and the air in the bottle is behind drop in temperature, due to the inner contraction of gas.

Summary of the invention

The utility model purpose provides a kind of plug for vacuum bottle, effectively solves existing problem in the background technology.

In order to solve existing problem in the background technology, it comprises the bottle stopper body, the middle part of this bottle stopper body is provided with the hole of up/down perforation, the lower end in this hole is provided with airway, its upper end is the air flue that overflows, the top of air flue that overflow is recess 7, described airway, the center of circle of excessive air flue and recess 7 is on the same axis, plug is arranged in the airway, this plug integral body is conical, button in its upper end is passed excessive air flue and is arranged on recess 7 by connecting rod is fixedly connected with, and extension spring is enclosed within on the connecting rod, and its lower end is fixedly connected with plug, its upper end is fixed on the sidewall of the air flue that overflows, between airway and excessive air flue, be provided with the scalene cone of applying plug, extension spring when plug is applied pulling force, plug just can automatic blocking on the scalene cone between airway and the excessive air flue.

Scribble antirusting paint in the described extension spring.

Owing to having adopted above technical scheme, the utlity model has following beneficial effect: simple in structure, be skillfully constructed, because under the effect of plug in extension spring, so that the air pressure in the bottle is suitable with the outer air pressure of bottle all the time, be very easy to when extracting, and the effect that plug has also played well and air is isolated, even the situation that bottle stopper is held occurs, only button need be pressed and put into gas, can reach the purpose of air pressure balance.

Description of drawings

In order to be illustrated more clearly in the utility model, the below will be to doing simple introduction to embodiment by reference to the accompanying drawings.

Fig. 1 is structural representation of the present utility model.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, the accompanying drawing below in conjunction with among the utility model embodiment is clearly and completely described the technical scheme among the utility model embodiment.

Referring to Fig. 1, this specific embodiment is to be achieved by the following technical solutions, it comprises bottle stopper body 1, the middle part of this bottle stopper body 1 is provided with the hole 2 of up/down perforation, the lower end in this hole 2 is provided with airway, its upper end is the air flue that overflows, the top of air flue that overflow is recess 7, described airway, the center of circle of excessive air flue and recess 7 is on the same axis, plug 3 is arranged in the airway, and these plug 3 integral body are conical, and the button 5 in its upper end is passed excessive air flue and is arranged on recess 7 by connecting rod 4 is fixedly connected with, extension spring 6 is enclosed within on the connecting rod 4, its lower end is fixedly connected with plug 3, and its upper end is fixed on the sidewall of the air flue that overflows, and is provided with the scalene cone of applying plug 3 between airway and excessive air flue, extension spring 6 when plug 3 is applied pulling force, plug 3 just can automatic blocking on the scalene cone between airway and the excessive air flue.

Scribble antirusting paint in the described extension spring 6.

Owing to having adopted above technical scheme, this specific embodiment has following beneficial effect: simple in structure, be skillfully constructed, because under the effect of plug in extension spring, so that the air pressure in the bottle is suitable with the outer air pressure of bottle all the time, be very easy to when extracting, and the effect that plug has also played well and air is isolated, even the situation that bottle stopper is held occurs, only button need be pressed and put into gas, can reach the purpose of air pressure balance.

It should be noted that at last: above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
