Technical Field

The utility model relates to an aerify the field, concretely relates to fill gassing break-make structure.

Background

The traditional inflation product is inflated by inserting the inflation needle into the inflation channel, after the inflation needle is pulled out of the inflation channel, the inflation channel can be automatically closed (the inflation channel has a very small inner diameter of a capillary channel and can prevent gas from leaking outwards), and the traditional inflation and deflation on-off structure has the defect that the inflation needle must be kept inserted into the product during deflation, the inflation needle is used as the deflation channel, the deflation cannot be carried out without the inflation needle, and the deflation cannot be flexibly adjusted according to the requirements of users.

SUMMERY OF THE UTILITY MODEL

There is above-mentioned defect to prior art, the utility model provides an it constructs to fill gassing break-make, concrete technical scheme as follows:

an inflation and deflation on-off structure comprises an inflation main body, a connecting body and a movable air-closing ring, wherein the inflation main body is connected with the connecting body into a whole, an inflation cavity is arranged in the inflation main body, the inflation main body is of a thin-wall structure and expands when gas enters the inflation cavity, at least a first channel, a second channel and a third channel are arranged in the connecting body, the upper end of the first channel is communicated with the inflation cavity, the lower end of the first channel is communicated with the second channel, the lower end of the second channel is communicated with the third channel, the movable air-closing ring is arranged on the outer side of the connecting body, and the movable air-closing ring is positioned at the position of the periphery of the third channel; the third channel is closed, the inflation chamber is not communicated with the outside, and the movable air-closing ring is positioned at other positions except the periphery of the third channel; the third channel is opened, and the inflation chamber is communicated with the outside.

As an optimal proposal of the utility model, the utility model also comprises an inflation guide piece arranged at the bottom of the connecting body, and the inflation guide piece guides the inflation needle to penetrate into the channel.

As an optimized proposal of the utility model, the inflatable main body and the connecting body are made of elastic plastic.

The utility model has the advantages that: when the movable air-closing ring is positioned at the periphery of the third channel; the third channel is closed, the inflation chamber is not communicated with the outside, and the movable air-closing ring is positioned at other positions except the periphery of the third channel; the third channel is opened, the inflation cavity is communicated with the outside, the position of the movable air-closing ring is adjusted, so that the third channel is switched to be opened or closed, the inflation cavity can deflate flexibly, the inflation needle is not needed for deflation, the structural design is novel and ingenious, the practicability is high, and the use requirements are met.

Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:

in the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the indicated position or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood as appropriate by those of ordinary skill in the art.

As shown in fig. 1 to 4, an inflation/deflation on/off structure comprises an inflation main body 1, a connecting body 2 and a movable air-closing ring 3, wherein the inflation main body 1 is connected with the connecting body 2 into a whole, the inflation main body 1 and the connecting body 2 are made of elastic plastic and can expand when being elastic and inflated, an inflation chamber 11 is arranged in the inflation main body 1, the inflation main body 1 is of a thin-wall structure, when gas enters the inflation chamber 11, the inflation main body 1 expands, namely when the gas with very thin wall thickness of the inflation main body 1 is inflated into the inflation chamber 11, the inflation main body 1 can expand when being inflated, at least a first channel 4, a second channel 5 and a third channel 6 are arranged in the connecting body 2, the upper end of the first channel 4 is communicated with the inflation chamber 11, the lower end of the second channel 5 is communicated with the third channel 6, the inner diameter of the third channel 6 ensures that the gas can leak when the gas is not compressed, the movable air-closing ring 3 is arranged outside the connecting body 2, when the movable air-closing ring 3 is positioned at the periphery of the third channel 6; the third channel 6 is pressed and closed by the movable gas-closing ring 3, the gas-filling chamber 11 is not communicated with the outside, and the movable gas-closing ring 3 is positioned at other positions except the periphery of the third channel 6; the third channel 6 is opened, and the inflatable chamber is communicated with the outside through the first channel 4, the second channel 5 and the third channel 6 to be deflatable.

In particular, when the movable obturator ring 3 is not at the periphery of the third channel 6; the third channel 6 is opened, the inflation chamber 11 is communicated with the outside through the first channel 4, the second channel 5 and the third channel 6, and can be deflated, and the position of the movable air-closing ring 3 can be flexibly adjusted to realize deflation.

Specifically, the inflation and deflation on-off structure further comprises an inflation guide part 9 installed at the bottom of the connecting body 2, the inflation guide part 9 guides the inflation needle 7 to penetrate into the third channel 6, the inflation needle 7 is inserted into the third channel 6 from the bottom of the inflation guide part 9, and the port of the inflation needle 7 is inserted into the second channel 5.

To sum up, the utility model discloses fill gassing break-make structure's advantage lies in, as long as put aside the suit with activity ring 3 that closes during the gassing and arrive when other positions except third passageway 6 periphery, third passageway 6 switches on and just can deflate, need not be in addition with the help of inflating the needle, and the practicality is very convenient.

The above description is provided for the purpose of describing the present invention in more detail with reference to the preferred embodiments, and it should not be construed that the present invention is limited to these descriptions, and it will be apparent to those skilled in the art that the present invention can be implemented in many ways without departing from the spirit and scope of the present invention.
