Description

Tire low-voltage explosion-proof annunciator

The utility model relates to a kind of automobile tyre low pressure warning device, is tire low-voltage explosion-proof annunciator specifically.

Automobile is in operation, and prick to be leaked tire be recurrent, if chaufeur can not in time find, tire is scrapped, especially long distance haulage car, overweight because of loading, a tire is pricked, the another tire also can increase because of pressure, temperature is too high causes explosion, and economic loss is even more serious.The tire safety annunciator of existing use is made up of annunciator and probe holder, and probe holder is fixed on automobile front and back bridge and the tire adapter shaft, and probe keeps certain distance perpendicular to ground, and when low tyre, vehicle body sinks, and reports to the police after probe contacts to earth.This annunciator in use, when the tire pressure wretched insufficiency, the probe warning of just contacting to earth, can not in time find and stop the low pressure wearing and tearing of tire, minimally reduces economic loss, and runs into the situation of Uneven road, cause mistaking signal easily, make troubles to cruising.

For addressing the above problem, the purpose of this utility model provides a kind of air pressure alarm switch that utilizes and in time reports to the police, and can avoid the tire low-voltage explosion-proof annunciator of mistaking signal.

The purpose of this utility model is achieved like this: tire low-voltage explosion-proof annunciator, it comprises the air pressure alarm switch of being with the ventilation flue, lead to lead on this alarm switch and dispose projector connection plug, its ventilation flue is communicated with a gas and chews, this gas is chewed the tubulose gas that is assemblied in a lower end band inner convex platform and is chewed in the pedestal, its gas is chewed bottom in the pedestal and gas and is chewed and be provided with O-ring seal between the lower surface, gas is chewed the hold-down nut of top configuration through being threaded of pedestal, dispose valve inside through being threaded in the top gas that gas is chewed is chewed mouth, the top that gas is chewed is provided with the gas that is threaded and chews cap.

Characteristics of the present utility model are: easy to install quick, report to the police accurately and timely, and be applicable to that various dissimilar vehicles use.

Further specify below in conjunction with drawings and Examples.

Accompanying drawing is structure master's cutaway view of this tire low-voltage explosion-proof annunciator.

As shown in drawings, this tire low-voltage explosion-proof annunciator is to chew device by gas to constitute through ventilation flue's 2 connection air pressure alarm switches 1, and gas is chewed device and directly cooperated with tire valve.It includes gas and chews pedestal 5, and gas is chewed pedestal 5 and is threaded the body that inner convex platform is arranged at the bottom for top, and its sidewall has a gap, and the bottom disposes cushion rubber 6.Gas is chewed and is equipped with gas in the pedestal 5 and chews 7, and gas is chewed 7 sides and had ventilation flue 2 and be communicated with air pressure alarm switch 1.Gas is chewed on 7 configuration hold-down nut 8 and is chewed base thread with gas and be connected.Chew 7 top gas at gas and dispose valve inside 9 through being threaded in chewing mouthful, gas is chewed 7 top and is provided with the gas that is threaded and chews cap 10.After the tire valve pipe stretched into gas and chews in the pedestal 5, hold-down nut 8 locking gas chewed 7, and gas is chewed cap 10 and chewed 7 with gas and tighten, and makes whole gas chew the device sealing.Air pressure alarm switch 1 is provided with junction block, and through lead 3 connection plugs 4.

When tire pressure reduces, by gas chew 7 and ventilation flue 2 enter gaseous tension deficiency in the air pressure alarm switch 1, metal probe in the air pressure alarm switch 1 just cover is closed, pass to projector through lead by plug, send alerting signal, receptor in operator's compartment is connected with dynamic loud-speaker, sends signal and in time passes to chaufeur.

Chaufeur can be turned on gas and chew cap 10 to the tire tonifying Qi.

Claims (1)

1, a kind of tire low-voltage explosion-proof annunciator, include band ventilation flue's (2) air pressure alarm switch (1), lead to lead (3) on this alarm switch and dispose projector connection plug (4), it is characterized in that: ventilation flue (2) is communicated with a gas and chews (7), this gas is chewed the tubulose gas that is assemblied in a lower end band inner convex platform and is chewed in the pedestal (5), its gas is chewed bottom in the pedestal and gas and is chewed and be provided with O-ring seal (6) between the lower surface, gas is chewed the hold-down nut (8) of top configuration through being threaded of pedestal, dispose valve inside (9) in the top gas that gas is chewed is chewed mouthful through being threaded, the top that gas is chewed (7) is provided with the gas that is threaded and chews cap (10).
