Abstract
The utility model discloses an anti-freeze and anti-leaking air valve, for example an air valve used for the light vehicles of a bicycle, a tricycle, a motorcycle, etc. The appearance and the dimension of the anti-freeze and anti-leaking air valve are fundamentally the same as the appearance and the dimension of the existing air valve used by a bicycle, etc. A purpose made air nozzle, a pressure spring, and a rubber pad structure are adopted by the interior of the anti-freeze and anti-leaking air valve. The automatic compensation of a gap on the sealed position of the anti-freeze and anti-leaking air valve is realized. The inconvenience brought by freezing leakage, ageing leakage, breaking leakage, and an unreasonable structure which are caused due to the fact that a rubber air valve core is used inside the past air valve is overcome, and the seal of the anti-freeze and anti-leaking air valve is ensured.
Description
The present invention relates to a kind of improved valve that is mainly used in the traffic tool such as bicycle.
The valve of the existing traffic tool has two kinds substantially.A kind of is automobile with valve (this valve also is housed in part motorcycle, light cavalry, the racing car); Another kind of is bicycle, tricycle valve (this kind valve is also arranged in part motorcycle, the light cavalry).
The automobile valve mainly is made up of overcoat and core body two large divisions, and its core adopts the composite entity structure.The valve sealing part is the thin rubber pad, and core body is screwed in the valve cover.So: 1. being screwed into to have specialist tools; 2. inflate and to use special valve; 3. the thin rubber pad can't be repaired after going bad, and can only change whole core body, because technology is complicated, cost is higher; 4. core body contacts for tip face with overcoat, and material is a duroplasts, by the top screw tightening, when screw has looseningly slightly, will leak gas from here.For these reasons, this kind valve is not suitable for bicycle.
The valve of bicycle use at present mainly is made up of metal master, cover mother, metallic core and rubber core etc.Wherein rubber core be enclosed within metal-cored on, sealing is fully by rubber core.Owing to be subjected to the restriction of structure and rubber core performance, therefore: rubber core was endured cold and is followed the string when 1. winter, temperature was low, caused gas leakage; Rubber core wore out, is clamminess when 2. summer, temperature was high, caused gas leakage; 3. core body and overcoat are pressured tight rubber core sealings, usually are pressed down herein, cause gas leakage; 4. for preventing that metal-cored rotation from damaging rubber core, there are two openings valve overcoat top, and yielding curving inwardly behind this opening pressurized often caused and extracted and insert the core body difficulty; 5. the aperture of metal-cored bottom is by self tension force sealing of rubber pipe, is subjected to the restriction of size and material property, occurs leaking slowly phenomenon herein sometimes.
The inventor through research, test, has finished the present invention in order to solve always the existing problem of valve such as bicycle finally.
The purpose of this invention is to provide a kind of simple in structure, convenient and reliable, long service life, cost is low, makes us the valve of the relieved light traffic tool such as bicycle.
The valve basically identical that uses on outward appearance of the present invention and apparent size and the present bicycle, but its internal structure and principle are different fully.The present invention will be described in detail with reference to the accompanying drawings below.Accompanying drawing is a longitudinal section of the present invention schematic representation.
The present invention is made up of 11 parts.Material, apparent size, the effect of the corresponding part that uses on the rubber pad (11) wherein, metal gasket (10), metal nut (1), metal nuts (9) and (8), metallic sheath mother (3) and bicycle at present are just the same.
Three place's rubber seal, pad all adopt used rubber of present bicycle inner tube or the more better rubber of performance among the present invention.
Among the present invention, there is screw thread metal master (5) outside, and inner upper end is a macropore, and the lower end is an aperture.There is a circle platform big aperture junction, and its effect is to hold stage clip (7), inserts rubber cylinder with the level (6) at stage clip (7) top.
In the middle of putting in metallic sheath mother (3) is the valve (2) of a disk, and stretch out from overlap mother (3) top-portion apertures valve (2) upper end, blocks up to quilt cover mother (3) top sides platform.Be inserted in rubber washer (4) from valve (2) bottom, up to valve (2) disk bottom.
Metal master (5) is fixed on the inner tube of a tyre, in its macropore, puts into stage clip (7), insert rubber cylinder (6), will overlap female (3) together are tightened in metal master (5) together with valve (2) and seal washer (4) upper end in the upper end of stage clip (7).
Inflate and be achieved in that with leakproof pump adaptor is enclosed within valve (2) top that gas promptly enters by valve top aperture, backs down the rubber cylinder (6) that stage clip (7) compresses, and enters the inner tube of a tyre from main body (5) through macropore, aperture, till beating foot.Because stage clip (7) is pressed on rubber cylinder (6) valve (2) bottom all the time, blocked gas spilling from valve (2) bottom aperture.Owing to tighten cover female (3) and main body (5), just make main body (5) top compress rubber washer (4) and valve (2), stoped gas spilling from screw thread junction between main body (5) and the cover female (3).Owing to adopted special valve, stage clip and rubber pad, make the valve and the gap between rubber core that can't compensate originally become the valve and the stage clip rubber pad structure that can compensate automatically, so just guaranteed that inner tube of a tyre gas can not leak outside from valve.
Facts have proved, select the bigger stage clip of elasticity coefficient (7) for use, make rubber cylinder (6) tightly be pressed in valve (2) bottom, for inflating (particularly hand inflator) unlike inflating effort for the valve that uses at present.The present invention has overcome fully that valve such as present bicycle is existing to freeze leakage, the aging leakage and phenomenons such as fracture leakage, the phenomenon of light leak gas once by the valve place also can not occur, has solved the worry that valve cock for a long time leaks gas and brings to people.Because core body adopts the rubber cylinder of stage clip and better performances, its working life is at least more than 2 years, even renewal part is also very convenient, and simple in structure, used number of parts is similar with the part of bicycle valve at present, and cost is also basic identical.
