Abstract

The invention discloses a multifunctional dustproof cover used for a portable inflator. The multifunctional dustproof cover is characterized by comprising an inner ring and an outer ring; the inner ring is used for being arranged on an outer pipe of the inflator in a sleeving mode; one end of the inner ring and one end of the outer ring are integrally connected; the other end of the outer ring is suspended, and an elastic arm is formed; and the outer circumferential surface of the outer ring is provided with a sealing mechanism matched with a holding pipe of the inflator. The multifunctional dustproof cover used for the portable inflator has the advantages that the multifunctional dustproof cover is arranged in an installation groove of the outer pipe of the inflator in a sleeved mode, when the inflator is fixed to a clamping base and the clamping base is fixed to a bicycle frame, the end of the dustproof cover abuts against the upper end surface of the clamping base, the dustproof cover is arranged in the installation groove of the outer pipe in the sleeved mode, and the outer pipe of the inflator can be well prevented from sliding down, so that the inflator is firmly fixed to the clamping base; and meanwhile, the holding pipe is matched with the sealing mechanism on the outer ring of the dustproof cover, outside dust, water and other impurities can be prevented from entering the outer pipe, and the service life of the inflator is prolonged.

Description

A kind of multi-function dust-proof set and the inflator for portable inflator

Technical field

The present invention relates to be used for the inflator of tyre inflating in daily life, more particularly to it is a kind of for portable inflator Multi-function dust-proof set and the inflator.

Background technology

The open air Portable bicycle inflator that fans use of riding all is at present that portable inflator is fixed on into deck On, then deck is fixedly mounted on the vehicle frame of bicycle.Although this mode can easily carry inflator in bicycle On, but there is also problems with：First, after inflator is fixed on deck, jolting and shake, inflator because of ride Stack shell can downwards slide along fixed-direction so that fixation it is unreliable；2nd, when inflator not used time, outside dust, water meeting Into in inflator, the piston packing inside inflator is caused to damage, affect the service life of inflator, accelerate inflator Scrap.

The content of the invention

The technical problem to be solved is to provide one kind can prevent the impurity such as dust and water from entering inflator, while The multi-function dust-proof set and the inflator for portable inflator that inflator can be securely fixed on deck.

The present invention solve the technical scheme that adopted of above-mentioned technical problem for：It is a kind of to prevent for the multi-functional of portable inflator Dirt set, including inner ring and outer rings, described inner ring is used to being enclosed within the outer tube of inflator, one end of described inner ring and described One end integrally connected of outer shroud, the other end of described outer shroud is hanging, forms elasticity arm, sets on the outer circumference surface of described outer shroud It is equipped with for the sealing mechanism that is engaged of holding a writing brush or pen-write with inflator.

Further, described sealing mechanism includes the sealing ring on the outer circumference surface of the outer shroud for being integrally disposed upon described.

Further, the end of described outer shroud has been wholely set retaining ring, and the external diameter of described retaining ring is more than inflates Cylinder holds a writing brush or pen-write the internal diameter of end.

The inflator covered using described multi-function dust-proof, including outer tube, hold a writing brush or pen-write and dirt-proof boot, described outer tube it is cylindrical The mounting groove of annular is provided with side face, described dirt-proof boot includes inner ring and outer rings, and described inner ring sleeve is in described installation In groove, described inner ring towards described one end for holding a writing brush or pen-write and described outer shroud towards the described one end integrally connected for holding a writing brush or pen-write, The other end of described outer shroud is hanging, forms elasticity arm, is provided with for holding with described on the outer circumference surface of described outer shroud The sealing mechanism that pipe is engaged.

Further, described sealing mechanism includes the sealing ring on the outer circumference surface of the outer shroud for being integrally disposed upon described, When inflator is not used, described sealing ring is fitted close with the described inwall for holding a writing brush or pen-write, and realization holds a writing brush or pen-write between outer tube Sealing.

Further, the end of described outer shroud has been wholely set retaining ring, and the external diameter of described retaining ring is more than described The end that holds a writing brush or pen-write internal diameter, when inflator is fixed on deck, when deck is fixed on cycle frame, on dirt-proof boot only Move back on the upper surface that ring is withstood on the deck of the outer tube phase clamping of inflator, while retaining ring further presses against the end for holding a writing brush or pen-write, anti- While only the stack shell of inflator glides, also secondary seal can be realized between outer tube to holding a writing brush or pen-write for inflator, be further ensured that Sealing effectiveness.

Compared with prior art, it is an advantage of the invention that due to being provided with annular on the outer circumference surface of the outer tube of inflator Mounting groove, the multi-function dust-proof set is enclosed within mounting groove, and when inflator is fixed on deck, deck is fixed on vehicle When on frame, the end of dirt-proof boot is withstood on the upper surface with the deck of the outer tube phase clamping of inflator, and dirt-proof boot covers outside In the mounting groove of pipe, the outer tube that can well prevent inflator glides so that inflator is rigidly mounted on deck, together When, hold a writing brush or pen-write and be engaged with the sealing mechanism on dirt-proof boot outer shroud, can prevent the impurity such as dust, the water of outside from entering the interior of outer tube Portion, substantially reduces the damage caused to piston packing to impurity such as dusts, extends the service life of inflator, realizes dirt-proof boot One-object-many-purposes；Additionally, inflator is when in use, because one end of the outer shroud of dirt-proof boot is hanging, elasticity arm is formed, outer tube is coming During pushing back drawing, because the effect of elasticity arm greatly reduces the resistance produced with the contact for holding a writing brush or pen-write because of dirt-proof boot, make Obtain outer tube easily laborsaving during push-and-pull.
