Unequal expansion bottle stopper

Abstract

The invention discloses an unequal expansion bottle stopper which comprises a cover plate and an elastic plunger body, wherein the cover plate is connected with the elastic plunger body; a driving disc is arranged inside the inner cavity of the elastic plunger body; four support arms are arranged on the driving disc at equal interval peripherally; the top pressing parts of the support arms longitudinally encircle the circumferential wall inside the elastic plunger body and are connected with the circumferential wall inside the elastic plunger body in a propping manner; positioning guide pins fixed on the cover plate are connected with arc-shaped guide holes in the support arms and the driving disc in a penetration manner; a rotating handle passes through a locking hole and is inserted into a shaft hole of a rotating shaft of the driving disc; the driving disc can be driven to rotate by rotating the rotating handle, then the support arms are radially expanded and withdrawn, at the same time, the diameter of the elastic plunger body is also correspondingly increased or decreased, and rotation of the driving disc can be locked after the locking disc moves downwards to be meshed with the locking hole. The bottle stopper can be radially unequally expanded and withdrawn, and according to bottle bodies of different opening diameters, the bottle stopper can be adjusted to be applicable to the bottle openings, and thus the bottle openings can be sealed.

Description

technical field [0001] The invention relates to a bottle stopper, in particular to a bottle stopper with unequal expansion. Background technique [0002] Bottles and cans are widely used in daily life. These containers cannot be sealed without a cork. The structure and quality of the cork are related to whether the contents in the container can be preserved for a long time. In order to obtain a better sealing performance for the bottle mouth, someone invented an expansion-type bottle stopper (Notice No. 101372274). A moving member, the body member can be used for the first section of longitudinal movement, the elastic member is longitudinally expanded, so that it is firmly attached to the inner wall of the container opening, and the body member can be used for the second The longitudinal movement of the section makes the elastic member shrink radially so that the bottle stopper can be easily taken out from the opening of the container. Although this kind of bottle stopper h...

In order to obtain a better sealing performance for the bottle mouth, someone invented an expansion-type bottle stopper (Notice No. 101372274). A moving member, the body member can be used for the first section of longitudinal movement, the elastic member is longitudinally expanded, so that it is firmly attached to the inner wall of the container opening, and the body member can be used for the second The longitudinal movement of the section makes the elastic member shrink radially so that the bottle stopper can be easily taken out from the opening of the container. Although this kind of bottle stopper has a good cork function, it can only be used for Containers of one specification and caliber are used together and have the characteristics of one-time use

When the substance in the bottle needs to be kept for next use in daily life, or the empty bottle is used for secondary use, because the bottle stopper is for one-time use, the seal of the bottle mouth loses the original matching bottle stopper, and it is necessary to find Other bottle stoppers can be used instead, but other stoppers may not just fit the bottle mouth, so it is difficult to ensure that the bottle mouth achieves a good sealing effect, which affects the quality of the objects in the bottle
