Abstract

The invention relates to the technical field of articles for daily use, and discloses an auxiliary fastening mechanism for a thermos bottle plug, which comprises a plug body, an adjusting cavity is formed in the middle of the inner cavity of the plug body, a pull rod movably sleeves the middle of the plug body, a vent groove is formed in the middle of the pull rod, and an auxiliary block positioned on the outer side of the lower end of the pull rod movably sleeves the lower end of the adjusting cavity. The lower end of the auxiliary block is fixedly connected with an adjusting block, and the middle of the adjusting block is provided with an air suction groove communicating the vent groove with the lower portion of the plug body. Through the arrangement of an automatic pressurizing mechanism, when the interior of the thermos bottle is gradually cooled, internal air pressure is rapidly reduced, and a bottle plug is adsorbed to a bottle opening, under the action that negative pressure and a ball block the lower end of a vent groove, a pull rod moves downwards, and after an ejector rod ejects the ball upwards, an inner cavity of the bottle is communicated with the outside through the vent groove; therefore, outside air can quickly flow into the bottle to be pressurized, and the situation that the bottle plug cannot be pulled out due to the fact that the air pressure in the bottle is small is avoided.

Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to an auxiliary fastening mechanism for a thermos cork. Background technique [0002] A thermos bottle, also called a thermos bottle, cuts off heat conduction by using a double-layer vacuum bottle in the middle, and cuts off the hot water in the bottle and the heat convection by coating a silver reflective paint in the vacuum compartment to reflect heat radiation and block the heat convection through the plug. External heat conduction, so that the water in the bottle achieves a long-lasting heat preservation effect. [0003] When the traditional thermos bottle stopper is in use, due to problems such as different sizes or insufficient blockage between it and the bottle mouth, there is likely to be a gap, resulting in gas circulation between the hot water in the bottle and the outside world, making the thermos bottle's insulation effect poor and affecting the thermos bottle....
