Description

Bottle opener

Technical field:

The utility model relates to a kind of bottle opener, and particularly suitable is opened the bottle of cork encapsulation.

Background technology:

Existing bottle opener kind is many, and commonly used mainly is revolves pull-typely, forms by screwing in device and pull handle, during use, with screwing in the helical metal bar screw-in cork of device, pulls out bottle stopper.This bottle opener uses very inconvenient, both wastes time and energy, and causes the broken and crushing glass bottle opening of cork again easily.Also have a kind of vapour-pressure type bottle opener in addition, though overcome the drawback of revolving pull-type bottle opener, complex structure uses and carries inconvenience.

Summary of the invention:

The technical problems to be solved in the utility model is that bottle opener a kind of simple in structure, easy to use, safe and reliable is provided.

The utility model provides a kind of bottle opener of following structure for the solution that solves above technical matters and take is, it is by shell 4, needle tubing 2, and slide bar 3, capping 5 and head protector 1 are formed.Be characterized in, captive joint with needle tubing 2 in the lower end of slide bar 3, establish the piston 6 that is connected as a single entity with it in the upper end of slide bar 3, in the groove of this piston, be provided with the rubber piston ring 8 of socket on it, axis direction at slide bar 3 and piston 6 is provided with the through hole that communicates with each other and communicate with the needle tubing centre hole, along the axis direction of piston 6 establish fix in it and and the check valve 7 that communicates of its through hole, on the inwall of shell 4 bottoms, be provided with inner convex platform, inner convex platform cooperates with the external diameter of rubber piston ring 8 with the internal diameter of outer cover on top, constitute the tracheae device, form running-fit between the external diameter of inner convex platform with the internal diameter of outer cover of lower part and slide bar 3, help the slip of slide bar.

A kind of embodiment preferably of the utility model is that piston 6 grooves are inverted round table-like with the outside diameter wall on top, help the downslide of piston like this.

Second kind of the utility model embodiment preferably be, the upper end diameter of rubber piston ring 8 is big, and lower end diameter is little, is bowl-shape.Like this, when slide bar 3 and piston 6 moved down, rubber piston ring 8 is close on the outside diameter wall of piston 6, and was little, laborsaving with internal diameter of outer cover wall friction power.

The utility model the third preferably embodiment be, on piston 6 outside diameter wall, be provided with 2--4 admission port, when slide bar moves up, help gas and enter in the outer shell cavity.

Because the utility model has adopted above technical solution, so, compared with prior art, have advantage simple and reasonable for structure, easy to use, time saving and energy saving, can be widely used in hotel, restaurant and family and use.

The I portion enlarged drawing of Fig. 2-Fig. 1

The A-A of Fig. 3-Fig. 2 is to view

The specific embodiment:

Provide embodiment of the present utility model below in conjunction with accompanying drawing, be used for further specifying technical solution.

Embodiment 1.Contrast Fig. 1, Fig. 2, Fig. 3 find out.The bottle opener structure that present embodiment provides is that it is made up of head protector 1, needle tubing 2, slide bar 3, shell 4, capping 5, piston 6, check valve 7 and rubber piston ring 8.The lower end captive joint of slide bar 3 needle tubing 2, the upper end captive joint of slide bar 3 piston 6, piston 6 grooves are inverted round table-like with the outside diameter wall on top, rubber piston ring 8 is socketed in the groove of piston 6, its upper end diameter is big, lower end diameter is little, is bowl-shape, coincide with piston 6 inverted round table-like outside diameter wall and touches mutually.Two induction openings 9 are positioned on the piston 6 inverted round table-like outside diameter wall, and communicate with the groove of piston 6.Axis direction at slide bar 3 and piston 6 is provided with the through hole that communicates with each other and communicate with the needle tubing centre hole, along the axis direction of piston 6 establish fix in it and and the check valve 7 that communicates of its through hole, on the inwall of shell 4 bottoms, be provided with inner convex platform, inner convex platform cooperates with the external diameter of rubber piston ring 8 with the internal diameter of outer cover on top, constitute the tracheae device, form running-fit between the external diameter of inner convex platform with the internal diameter of outer cover of lower part and slide bar 3, help the slip of slide bar.

Principle of work: during use, back out head protector 1, holding shell 4 makes needle tubing 2 prick the cork of saturating bottle, at this moment upwards spur shell 4, be subjected to suction function, check valve 7 is closed, air can only be from shell 4 endoporus and gap that slide bar 3 external diameters cooperate admission port by piston 6 upper ends enter top in the shell 4.At this moment reversing sense promotes shell 4 again, because the external diameter and shell 4 inwalls of rubber piston ring 8 closely cooperate, gas can only enter in the check valve 7 and open it, gas enters in the bottle through needle tubing by the through hole of piston 6 and slide bar 3 again, so repeatedly several times, gas in the bottle increases gradually, and after reaching certain pressure, cork is being released from bottle by gas of nature just.

In like manner, according to the technical solution that the utility model provides, can also provide the embodiment of following structure.As comparing with embodiment 1, the structure of other parts is constant, and its improvement only is, the outside diameter wall of piston 6 is not inverted round table-like, but isometrical columned bottle opener; The structure of perhaps comparing other parts with embodiment 1 is constant, and its improvement only is that rubber piston ring 8 is not that upper end diameter is big, the bowl-shape piston ring that lower end diameter is little, but the bottle opener of isometrical rubber piston ring; The structure of perhaps comparing other parts with embodiment 1 is constant, and its improvement only is, induction opening 9 is not bottle opener of two but 3 or the like.
