Bottle cap opening and closing assist device

Abstract

The invention provides a bottle cap opening and closing assist device, and belongs to the technical field of bottle openers. The bottle cap opening and closing assist device comprises a sliding pin reverse stop buckle, a sliding pin reverse stop buckle pressing spring, a sliding pin pressure spring, a sliding pin, an eccentric wheel reset elastic belt, an eccentric wheel, an eccentric wheel rotating shaft, an unlocking rod, an unlocking rod ejector rod, an unlocking rod ejector rod pressure spring and a main frame grip. The bottle cap opening and closing assist device is buckled to the upper end face of a bottle cap, a hand pinches the main frame grip to rotate and amplify torque, and the eccentric wheel and the bottle cap can generate relative friction rolling, so that the bottle cap is tighter and tighter in rotation, relative slippage is prevented until the bottle cap is screwed, and the purpose of easily and conveniently opening the bottle cap without damage is achieved.

Description

technical field [0001] The invention relates to the technical field of bottle openers, in particular to a bottle cap opening and closing assistant. Background technique [0002] The bottle opener is an indispensable tool in people's daily life. At present, the existing bottle openers (such as the Chinese patent of CN201610684642.7) all use strong external force to lift the bottle cap, and then manually unscrew it. Bottle caps; this method tends to damage the caps, making it impossible to screw the caps back on to the bottle after use; [0003] In addition, for some bottle caps that are particularly difficult to twist, it is difficult for women and children to open the bottle due to reasons such as weak hand grip and slippery hands. Therefore, it is urgent to invent a bottle cap that can be applied to different diameters and different specifications and shapes. And the bottle cap opening and closing assistant that can easily and conveniently open the bottle cap without damag...

Problems solved by technology

[0002]The bottle opener is an indispensable tool in people's daily life. At present, the existing bottle openers (such as the Chinese patent of CN201610684642.7) are all applied by people. After the bottle cap is lifted by a strong external force, the bottle cap is forcibly unscrewed manually; this method often damages the bottle cap, making it impossible to tighten the bottle cap to the bottle again after use;

[0003] In addition, for some bottle caps that are particularly difficult to twist, it is difficult for women and children to open the bottle due to reasons such as weak grip strength, sticky oil and water slippery hands; therefore, There is an urgent need to invent a bottle cap opening and closing assistant that can be applied to bottle caps of different diameters and shapes and can easily and conveniently open the bottle cap without any damage to solve the above problems
