Abstract

The utility model relates to a tire pressure alarm whistle. A connector is screwed on an air receiving pipe of a tire; an air pipe connects the connector and a barrel body; a piston, a spring and a baffle are arranged in the barrel body; and one end of the baffle extends out of the upper end surface of the barrel body and seals a whistle opening fixed on the upper end surface of the barrel body. When the air pressure in the tire rises and exceeds the standard, the baffle moves upwards under the action of the air pressure in the tire, a high pressure opening is right targeted at the whistle opening, and an air stream generated by the rotation of the tire enters the whistle opening and produces sharp whistles. When the air pressure inside the tire is lower than the standard pressure, the spring tension inside the barrel body is higher than the air pressure in the tire, so that the baffle moves downwards, the low pressure opening is opened, and the air stream enters the whistle opening and produces whistles to alarm a driver to stop to check, thereby ensuring driving safety.

Description

A kind of tire pressure caution whistle

Affiliated technical field

The utility model relates to a kind of tire pressure prior-warning device, specifically a kind of warning whistle of tire pressure.

Background technology

Now, automobile enters common people family just in a large number, it is more important that driving safety just seems, because the too high or too low traffic accident that causes of air pressure of tire is of common occurrence, carelessness during inflation, the speed of a motor vehicle is too fast, the gas leakage that a variety of causes causes, the variation of road and ambient temperature all can cause the too high or on the low side of tire internal pressure.Tire pressure departs from standard, will cause the direction shakiness, even the flat tire of blowing out, and tends to cause traffic accident, still, automobile under steam, navigating mate is difficult to obtain the pressure information in the tire, when stopping or just know barometric information in the tire afterwards.

The utility model content

In order to solve the deficiency that automobile can't obtain tire air pressure information in motion, the utility model provides a kind of tire pressure caution whistle, can report to the police to tire pressure is too high or too low in running car in this caution whistle, prompting navigating mate parking checking is guaranteed driving safety.

The utility model solves the technical measures that its technical matters takes, and joint flexibly connects breather pipe, establishes thimble in the breather pipe, and breather pipe is installed piston with the staving that is threaded in the staving, formation fully enclosed energy chamber between piston and the breather pipe.The piston upper surface is provided with spring and baffle plate, the lower end of baffle plate is fixed on the piston upper surface, stretch out outside the staving baffle plate upper end, establish low pressure port and high-pressure mouth above the baffle plate, when the high-low pressure mouth of baffle plate changes at the tire internal gas pressure, can open and cover the mouth of the whistle body that is fixed on the barrel top cover, whistle body subscript directional arrow.During use joint is spun on being subjected on the pneumatic tube of tire, with the arrow of sight vane hand of rotation towards tire, thimble in the breather pipe backs down the vent plug that is subjected to tracheae, pressure air in the tire enters in the energy chamber of staving, when standard pressure, the spring tension of piston top and the equilibrium of pressure in the energy chamber are fixed on the position of piston overhead gage, just in time cover whistle mouth, making whistle mouth not have air flows through, activating alarm sound not, automobile under steam, the air pressure in the tire is because a variety of causes when raising, pressure in the energy chamber is greater than the tension force of spring, piston is upwards pushed away, drive on the baffle plate and move, when air pressure the going up in limited time of air pressure that be above standard, high-pressure mouth on the baffle plate, just in time aim at whistle mouth, the air-flow during the tire rotation enters whistle mouth, sends sharp warbling of the oriole chimes of doom.When the air pressure in the tire reduces, the tension force of spring is greater than the pressure in the energy chamber, the promotion piston moves down, when air pressure is lower than standard pressure, the low pressure port of baffle plate is just in time aimed at whistle mouth, and air-flow enters whistle mouth and sends chimes of doom, to remind the navigating mate parking checking, can obtain tire air pressure information in motion thereby reach automobile, guarantee the purpose of driving safety.

The beneficial effects of the utility model are, settle the air pressure caution whistle on the tire, make navigating mate can in time obtain pressure information in the tire in running car, avoid the accident potential because of tire pressure existence when too high or on the low side.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the structural representation at a kind of tire pressure caution whistle.

Among the figure, 1, joint, 2, seal ring, 3, thimble, 4, breather pipe, 5, energy chamber, 6, piston, 7, staving, 8, spring, 9, baffle plate, 10, high-pressure mouth, 11, low pressure port, 12, whistle body, 13, sight vane.

The specific embodiment

In Fig. 1, joint (1) flexibly connects breather pipe (4), and seal ring (2) fills up between connection for breather pipe, and thimble (3) is fixed in the breather pipe, and breather pipe connects the lower end of staving (7) with screw thread.Piston (6) is installed in the staving, forms sealing air chamber (5) below the outer circular boop seal ring (2) and between the breather pipe, above fixed dam (9), high-pressure mouth (10) and low pressure port (11) are opened in the upper end of baffle plate, on the staving with the top cover that is threaded.Spring (8) is installed between piston and the top cover, fixing whistle body (12) on top cover, and slot is opened in the centre of top cover, and baffle plate stretches out from this hole and blocks whistle mouth, and sight vane is located at body top, the whistle, and arrow is towards whistle mouth.

Claims

1, a kind of tire pressure caution whistle, joint flexibly connects breather pipe, and the breather pipe staving that is threaded is installed piston, spring in the staving, and it is characterized in that: baffle plate is fixed on the piston head, and the upper end is stretched out to seal and is fixed on the whistle body mouth that staving covers.

2, a kind of tire pressure according to claim 1 is warned the whistle, it is characterized in that: high-pressure mouth and low pressure port are opened in the baffle plate upper end.

3, a kind of tire pressure according to claim 1 is warned the whistle, it is characterized in that: thimble is set in the breather pipe.
