More Information
Summary:The utility model discloses an anti-hypothermia liquid compression piston for a vacuum bottle, which comprises a body, a boss arranged in the body, a hole arranged in the middle of the boss and at least three claws arranged at the basewall of the hole. The anti-hypothermia liquid compression piston for a vacuum bottle in the utility model has the following beneficial effects: the claws at the bottom part of the piston can be automatically tightened when in hypothermia expansion, and automatically stretches and returns to the original state when the temperature goes back to the normal temperature, so as to achieve the purpose of anti-hypothermia compression, thus ensuring non-drop of the cork base.
