Abstract
The utility model provides a lack-of-air alarm device for tyre, belonging to the field of lack-of-air machinery alarm devices for the tyre during the driving of vehicles. The utility model is composed of a rubber outer shell 1, a spring 3, rubber pads 2 and 4 and an air whistle 5, wherein, the rubber outer shell 1 is a discus-shaped bark pocket; the spring 3 is arranged at the central position in the rubber outer shell 1; the rubber pads 2 and 4 are placed between the rubber outer shell 1 and the spring 3; the air whistle 5 can be horizontally and vertically inlaid on a shell body of the rubber outer shell 1. The utility model carries out alarm through the air whistle according to change of pressure difference between elastic restoring force of the spring and air pressure force in the tyre. Due to simple structure and the adoption of a pure mechanical device to carry out alarm, the utility model has the advantages of low cost and high reliability.
Description
The utility model is a kind of flat tire alarm device, belongs to tire deflation mechanical alarm device field in the vehicle operating, and international classification number is G08B21/00.
The number of patent application of having announced is that 85201844.4 the mechanical type tire annunciator that loses heart is that the width and the annunciator of tire tripe during with tire deflation reported to the police to the ground-surface discrepancy in elevation.Increase by tire tripe width when being tire deflation makes the tire tripe contact with the probe flange, and then passes through the insulation contact closure, makes to send signal with the connection of insulation contact check screw wire connecting and inform chaufeur.This formal cause vehicle operating produces vibrations, electric line long term exposure in reasons such as the external worlds, can make the electric line disconnection and cause warning malfunctioning.In addition, this form also is subjected to ground-surface restriction, and the road surface is uneven and also reports to the police, and is easy to create a false impression to chaufeur.
The purpose of this utility model is to overcome the damageable shortcoming of above-mentioned annunciator electric line, realizes the failure-free warning with pure mechanical device.
The utility model is made up of elastic caoutchouc shell, spring, the gentle sentry post of rubber pad.Rubbery outer cover is a discus shape leather bag.Spring is positioned at rubbery outer cover central authorities, and its axis direction is consistent with the rubbery outer cover centerline direction.Be placed with two rubber pads between rubbery outer cover and spring, they can avoid spring to act directly on the rubbery outer cover, prolong the warning device life-span.Spring can be post spring, tower spring etc.Gas whistle level, vertically be set on the rubbery outer cover housing, two ends flanged pin form is made at the gas whistle, so that the warning device unlikely gas whistle suction or the ejection rubber shell in air-breathing, exhaust process.
The utility model advantage is that part is few, and is simple in structure, is easy to make, and cost is low, and because of adopting pure mechanical device to report to the police, so the reliability height.
Below in conjunction with accompanying drawing the utility model is elaborated:
Fig. 1 is the warning device structural representation.
Warning device was bonded at the installation site scheme drawing on the wheel mouth skin when Fig. 2 was the wheel of vehicle inner tube free.
Fig. 3 is shaped on a flange and sets up the warning device structural representation at a gas whistle along its centerline direction lower end for rubbery outer cover.
Warning device was stuck in installation site scheme drawing on wheel mouth skin and the inner ring hole when Fig. 4 had the inner tube of a tyre for wheel of vehicle.
See Fig. 1, warning device is made up of rubbery outer cover 1, rubber pad 2, spring 3, rubber pad 4, the gas whistle 5.Rubbery outer cover 1 is a discus shape leather bag.Spring 3 is positioned at rubbery outer cover 1 central authorities, and its axis direction is consistent with rubbery outer cover 1 centerline direction, is placed with rubber pad 2,4 between rubbery outer cover 1 and spring 3.Rubber pad 2,4 can avoid spring 3 to act directly on the rubbery outer cover 1, prolongs the warning device life-span.The gas whistle 5 levels are set on the rubbery outer cover 1 excircle housing, and two ends flanged pin form is made at the gas whistle 5, so that warning device is unlikely in air-breathing, exhaust process the gas whistle 5 are sucked or ejection rubber shell 1.
See Fig. 2, during use warning device is bonded on the mouth skin 7 above the inner ring 8 that when cover tire 6 internal gas pressures were high, warning device can not be subjected to cover tire 6 compressings, warning device is inoperative.When cover tire 6 internal gas pressures are reduced to a certain degree, when warning device rotates to the wheel bottom, tire extrusion spring 3, the warning device exhaust, sound is sent at the gas whistle 5, and wheel rotates again, warning device is inflation again under the effect of spring 3 elastic force, exhaust again then makes the gas whistle 5 constantly send sound, informs chaufeur.
Fig. 3, Fig. 4 is a preferred embodiment of the utility model, sees Fig. 3, warning device is made up of rubbery outer cover 1, spring 3, rubber pad 2, the 4 gentle whistles 5.Rubbery outer cover 1 is a discus shape leather bag, and it is shaped on a flange along the centerline direction lower end, and adorns a gas whistle 5 at this place.Spring 3 is positioned at rubbery outer cover 1 central authorities, and its axis direction is consistent with rubbery outer cover 1 centerline direction.Be placed with rubber pad 2,4 between rubbery outer cover 1 and spring 3, rubber pad 2,4 can avoid spring 3 to act directly on the rubbery outer cover 1, prolongs the warning device life-span.This moment, the gas whistle 5 was two, and one along rubbery outer cover 1 excircle horizontal positioned, vertically placed in flange along rubbery outer cover 1 centerline direction for one.Two ends flanged pin form is made at the gas whistle 5, so that warning device is unlikely in air-breathing, exhaust process the gas whistle 5 is sucked or ejection rubber shell 1.See Fig. 4, during use warning device is installed between the inner tube of a tyre 9 and mouthful skin 7, is drilled with a hole on mouthful skin 7 and the inner ring 8, the flange diameter of warning device rubbery outer cover 1 lower end is slightly larger than mouthful skin 7 and inner ring 8 apertures, flange can be realized leak-tight joint, positiver sealing after being pressed into mouthful skin 7 and inner ring 8.Like this, send sound because of the gas whistle, rubbery outer cover 1 lower end 5 and directly pass, add the sound that send at the gas whistle 5 of horizontal positioned,, easily heard so sound is very big to the external world.The working process of this warning device is that when the inner tube of a tyre 9 internal gas pressures were high, warning device is crushed, and was inoperative; When the inner tube of a tyre 9 internal gas pressures are low to a certain degree the time, spring 3 elastic restoring forces are greater than the inner tube of a tyre 9 inner air pressures, and spring 3 is upspring, the warning device inflation, when warning device rotates to the wheel bottom, tire extrusion spring 3, warning device exhaust, sound is sent at the gas whistle 5, wheel rotates again, and warning device is inflation again under the effect of spring 3 elastic force, exhaust again then, make the gas whistle 5 constantly send sound, inform chaufeur.
