Abstract

The utility model discloses an expanding bottle stopper, comprising a stopper body (1), a pressure bar (3) and a holding handle (4). The expanding bottle stopper is characterized in that the stopper body (1) is provided with a column shape inner cavity (5), and the lower end of the stopper body is a conical surface. A column shape stopper head (2) is installed in the inner cavity (5), the lower end of stopper head (2) is also a conical surface, and the conicity of the conical surface of the stopper head lower end is smaller than the conicity of the lower portion of the inner cavity (5). The pressure bar (3) and the stopper head (2) are in an integral structure. The expanding bottle stopper has the features of bottle stopper locking function, rushing proof and leakage proof. The utility model has the advantages of favorable thermal insulating property, convenient operation and high reliability.

Description

Expanding bottle stopper

The utility model belongs to the bottle stopper field, is specially adapted to plug for vacuum bottle usefulness, also is fit to canteen and multiple bottle stopper and uses.

At present, plug for vacuum bottle generally adopts garden platform shape cork, overall plastic hollow plug and plastics combine plug etc. with cork, when above-mentioned bottle stopper is worked, only depend on the contact pressure jam-pack bottleneck of the conical surface and vacuum bottle bottleneck, there is not other locking measure, so that bottle stopper is usually washed open by the air pressure in the bottle easily, this influences the heat-insulating property of vacuum bottle on the one hand, on the other hand, bottle stopper is washed open sometimes and is dropped to the ground, and makes troubles to use.

For overcoming the prior art scheme is to open the inner chamber of the band conical surface on cock body, the cylindricality chock plug of the device band conical surface in the inner chamber, chock plug by depression bar and handle can be in aforementioned inner chamber up-and-down movement.Because chock plug is with conical surface tapering to be with conical surface tapering less than the cock body inner chamber, the up-and-down movement of chock plug can produce the radial expansion of cock body, thereby realizes the purpose of this utility model.

Below in conjunction with description of drawings concrete structure of the present utility model is described in detail as follows:

Fig. 1 is the utility model structural representation.

As shown in Figure 1, the utility model is made up of cock body (1), depression bar (3), handle (4), is characterized in having on the cock body cylindrical inner chamber (5), and its underpart is a conical surface, cylindricality chock plug (2) is housed in aforementioned inner chamber, and the conical surface is also made in the lower end of this chock plug (2). The tapering of its taper ratio cock body inner chamber (5) bottom conical surface is little, and depression bar (3) is overall structure with chock plug (2). During assembling, the movable chock plug of all-in-one-piece processed (2) and movable depression bar (3) are packed into by the lower end of cock body (1), load onto handle (4) in the upper end of depression bar (3), between chock plug (2) and the cock body inner chamber (5) for being slidingly matched, In order to improve the performance that is radially expanded of cock body, cock body inner chamber (5) with the conical surface have cannelure (6).

During use, cock body (1) is filled in the bottleneck, then with depression bar (3) gently to pressing down, at this moment the conical surface of conical surface extrusion plug intracoelomic cavity (5) bottom of chock plug (2) lower end, force the part of the close cannelure (6) in lower end of cock body (1) a little outwards to expand, increase cock body (1) and the contact force that is incubated the bottleneck inwall, and cock body (1) and bottleneck inwall are fitted tightly. Thereby reach the purpose of erosion control leakproof, heat insulation effect like this, obviously better than prior art, the selection of movable chock plug (2) lower end conical degree of conical surface can upwards not withdrawed from voluntarily with chock plug (2), namely has auto-lock function and is as the criterion, during opening stopper, only need depression bar (3) is upwards mentioned, the conical surface of chock plug (2) lower end leaves cock body inner chamber (5) the bottom conical surface, and cock body inner chamber (5) the bottom conical surface becomes lax release conditions, cock body (1) lower end can be extracted bottle stopper gently to contraction.

The utlity model has the characteristics of erosion control leakproof, good heat insulating, easy to use and reliable, simple in structure, be easy to make, this utility model also can make the canteen plug and multiple bottle stopper is used.

Claims

1, a kind of Expanding bottle stopper, comprise cock body (1), depression bar (3), handle (4), it is characterized in that a cylindrical inner chamber (5) is arranged on the cock body (1), its lower end is the conical surface, there is a cylindricality chock plug (2) to be contained in the aforementioned inner chamber (5), the lower end of this chock plug (2) also is the conical surface, and tapering is less than the tapering of inner chamber (5) the bottom conical surface, and described depression bar (3) is an integral structure with chock plug (2).

2,, it is characterized in that on the conical surface of described cock body inner chamber (5) bottom, having circular groove (6) by the described Expanding bottle stopper of claim 1.
