Description

A kind of gas nozzle that can improve leakproofness

Technical field

The utility model is related to gas nozzle fields, more specifically, it relates to a kind of gas nozzle that can improve leakproofness.

Background technology

Aerated product refers to the product of the draught head formation shape inside and outside stretching force and film using thin-film material manufacture. It is usually provided with gas nozzle on aerated product, and then conveniently aerated product is inflated and is vented.

Existing notification number is that the Chinese patent of CN204985883U discloses a kind of gas nozzle of quick inflation/deflation, including bottom Seat, sealed film, sponge gasket and fixinig plate, pedestal top is equipped with lid plug chamber, middle part is equipped with air admission hole, lower part is equipped with and blocks Chamber, lid plug intracavitary side are equipped with catching groove；Welded ring is equipped on the outside of lid plug chamber, welded ring side is equipped with frenulum, the connection of the frenulum other end There is lid to fill in；Side is equipped with retaining ring and sealing ring, lid plug insert cover plug intracavitary to lid beyond the Great Wall, and retaining ring buckles into catching groove, and sealing ring is filled in lid Chamber side wall is fitted into the leakproofness for reinforcing air admission hole；As can be seen that catching groove setting is filled in lid from patent specification attached drawing Intracavitary is close to one end of air inlet.

But catching groove is arranged in lid plug intracavitary close to one end of air inlet, then lid fills in chamber meeting during retaining ring buckles into catching groove Larger deformation occurs, and in order to enable lid plug chamber to deform, then need the hardness for reducing pedestal；Although side is provided with lid beyond the Great Wall Sealing ring, but the lid plug chamber being easily deformed still can influence the leakproofness of gas nozzle.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of gas that can improve leakproofness Mouth has the advantage that can improve leakproofness.

To achieve the above object, the utility model provides following technical solution：

A kind of gas nozzle that can improve leakproofness, including gas seat and the patch that is connect with gas seat are opened among the gas seat Equipped with the first stomata, the vent plug coordinated with the first stomata is provided on the patch；The vent plug side wall is close to one end of patch Protrusion is provided with snap ring, and the first stomata inner wall depression is provided with the card slot coordinated with snap ring.

By using above-mentioned technical proposal, because snap ring is arranged in vent plug side wall close to one end of patch, the first gas Smaller deformation, which occurs, for hole can make in snap ring insertion card slot, and then can improve the hardness of gas seat, and gas seat is made to be not susceptible to Deformation, so as to improve the leakproofness of gas nozzle；Snap ring is arranged in vent plug side wall close to one end of patch simultaneously, thus vent plug with The contact area of first stomata is big, and then can improve the leakproofness of gas nozzle.

Further, first stomata is close to the rounded setting in one end of card slot.

By using above-mentioned technical proposal, the first stomata can conveniently make vent plug embedding close to the rounded setting in one end of card slot Enter in the first stomata.

Further, the described one end of gas seat far from card slot uniformly offers several deformation slots.

By using above-mentioned technical proposal, deformation is happened at deformation slot when installing gas seat, and then can reduce gas seat Whole deformation quantity, so as to improve the leakproofness of gas nozzle.

Further, the described one end of gas seat inner wall far from card slot offers the reduced thickness groove being connected to deformation slot.

By using above-mentioned technical proposal, the thickness that reduced thickness groove can be such that gas seat is located at deformation slot is reduced, and then can It is easy to make to deform upon at deformation slot.

Further, offer aeration tank among the vent plug, and one end far from patch uniformly offer it is several with fill The second stomata and be provided with the diaphragm seal for being closed several second stomatas that air drain is connected to；The patch is connected with cover board, institute State the sealing ring being provided on cover board for being embedded in aeration tank.

By using above-mentioned technical proposal, diaphragm seal deforms under the influence of gas when inflation, so as to pass through Second stomata is inflated；The second stomata is closed by diaphragm seal under the influence of air pressure after the completion of inflation, while sealing ring is embedding Enter in aeration tank, and then the leakproofness of gas nozzle can be improved.

Further, the one end of the patch far from vent plug is symmetrically arranged with limiting plate, shape between two limiting plates At the limiting slot coordinated with cover board.

By using above-mentioned technical proposal, limiting slot plays position-limiting action to cover board, and then can prevent cover board from occurring to turn It is dynamic, so as to improve the leakproofness of gas nozzle.

Further, several anti-skid bulges are provided on the cover board.

By using above-mentioned technical proposal, anti-skid bulge can increase the frictional force between hand and cover board, and then convenient logical Cover board is crossed to be detached from sealing ring and aeration tank.

Further, the diaphragm seal is set as being detachably connected with vent plug.

By using above-mentioned technical proposal, diaphragm seal is set as being detachably connected to facilitate and be carried out to diaphragm seal with vent plug It replaces.

In conclusion the utility model has the advantages that：

1, snap ring is used to be arranged in vent plug side wall close to one end of patch, to generate the effect for improving leakproofness；

2, deformation slot and reduced thickness groove are used, to generate the effect for improving leakproofness；

3, limiting plate is used, to generate the effect for improving leakproofness.
