Description

PRESSURE CAP FOR REGULATING AIR PRESSURE OF TIRE}

The conventional tire test was a basis for evaluating the acceptance of the tire by the "sense" of pressing the tire with the user's hand or the "observation" of the eye. However, different vehicle types and different tire structures have different tire characteristics. In the conventional method, since tires are judged in an approximate manner, such as touching by hand or observing with the eyes, the pressure values of the tires are different from each other, and thus a pressure difference easily occurs. Inadequate tire pressure control can lead to unbalanced driving, which can lead to unexpected accidents. Therefore, various tire tire pressure gauges have been developed and used to survey tires. However, the majority of tire pressure gauges can be used for temporary surveys, but the user has not been able to grasp the actual condition of the tire from time to time. Later, the tire pressure cover, which is installed in the air hole of the tire, was developed so that the pressure cover of the tire could be checked at any time by the pressure cover of the tire, but there was still a measurement error, and the color of the parts was easily discolored A defect such as this tending to one side easily occurred.

In view of the above, the inventors have further researched and developed a kind of tire pressure indicator as a precise, durable, and easily observable surveying device.

The present invention is a device to sufficiently inject the high pressure gas inside the tire into the pressure cover of the present invention by screwing the metal outer case to the wind hole of the tire, when the gas passes through the air vent pieces, the rubber packing is pushed out As the buoy rises, it compresses the spring. Once the buoy has penetrated the alarm stopper, the user can accurately determine whether the tire pressure is sufficient by monitoring the color of the alarm stopper before the alarm stopper is covered by the buoy.

Inside the metal outer case 2 and the transparent cover 1, components such as the ventilation piece 3, the rubber packing 4, the buoy 5, the spring 9, and the alarm display cap 6 can be installed. . The vent piece 3 is installed above the metal outer case 2 and below the upper hole trough 23, and the vent piece 3 is a combination of the disc 32 and the projection 33, and the disc At least one vent hole 31 is provided on the top 32, and the protrusion 33 is used to press the plug inside the tire wind hole. Next, a rubber packing 4 is installed above the ventilation piece 3, and this rubber packing is provided with a concave recessed rim 41 and a conical convex cone 42, and this rim 41 Is fitted in the hollow underlay 51 of the buoy 5. The underlay 51 can also be attached to the convex cone 42 and thus can achieve a rigid joining effect. And the buoy 5 has a stepped columnar shape, the diameter of the hollow upper end 52 of the upper end is larger than the hollow underlay 51 of the lower end. There is one separation layer 53 between the upper and lower bodies, and there is a convex plug 54 on the separation layer. On the other hand, the inside of the hollow upper end 52 can be fitted with a spring 9, the radius of the lower end of the spring 9 is relatively large so as to be fitted with the convex stopper 54, the upper end is a hollow alarm display stopper 6 ) To fit inside.

On the surface of the alarm indicator cap 6 there are two color sections, yellow and red, with yellow at the top and red at the bottom. In the drawings, reference numeral 63 denotes a yellow plug portion and reference numeral 62 a red plug portion. The upper surface of the alarm display cap 6 is made of a yellow disk 63, and a tape 61 can be stuck on the disk. This tape 61 displays the tire pressure pound value (this tire pressure pound value is determined by the tire size, model number and tire pressure value of the tire design produced by each manufacturer. Therefore, springs of different sizes are used. Installing (9) gives pressure values for different tires). After pasting the tape 61, the user can visually see the pound value of the tape 61 (as shown in the three-dimensional explanatory drawing of FIG. 3) outside the transparent lid 1, so that the user can Tire pressure covers should be used. In addition, a convex leak-proof gasket 7 is installed, and a hole 71 is provided at the center thereof, and is installed below the plug hole 24 of the metal outer case 2 to prevent the air from leaking. Is used.

Among them, the leak-proof gasket 7 is provided so as to be tightly sealed under the plug hole 24, and the ventilation piece 3 is closely attached to the bottom of the groove 25 passing upward. And the rubber packing 4 is provided in the inside of the upper hole cylinder 23, and the buoy 5 is supported. The hollow upper end 52 of the buoy 5 supports the spring 9, and on top of the spring 9 a hollow alarm stopper 6 is fitted again. Then, the transparent packing 1 and the metal outer case 2 are tightly bonded up and down with a strong adhesive and then permanently sealed and cannot be removed again. When leaking, you won't be able to put your aircraft.

3 is a three-dimensional external appearance drawing of the present invention, wherein the tire pressure cover 10 at this time shows a state before joining the tire wind hole 8. The alarm display stopper 6 at this time is not affected by the original restoring force of the spring 9 and does not show any reaction. In addition, the buoy (5) is also affected by the original recovery of the spring (9) shows no reaction. But these two locations are one on the top and one on the bottom. In addition, the user can see two sections of the yellow stopper 63 and the red stopper 62 of the alarm display stopper 6 through the transparent cover (1).

After the tire pressure cover 10 of the present invention is coupled to the wind hole 8 of the tire with a screw, a state as shown in FIG. 4 appears. The protrusion 33 of the vent piece 3 operates the support nail 82 inside the wind hole 8. When the support nail 82 descends, the spring 81 is pressed to compress the spring so that the high pressure gas inside the tire enters the inside of the tire pressure cover 10 via the hole 83 of the wind hole 8. do. When the gas enters the tire pressure cover 10, the gas passes through the air vent 31 of the air vent piece 3, and the rubber packing 4 is forced to rise. At this time, the rubber packing 4 rises to press the buoy 5 to rise and compress the spring 9 inside the alarm stopper 6. At this time, the yellow and red portions 62 and 63 of the alarm display cap 6 are covered by the hollow upper end 52 of the buoy 5.

Since the spring 9 itself has elastic resilience, different tire pressures will result in different elevations of the buoy 5. If the tire pressure is low, the buoy 5 will automatically lower the height. As shown in FIG. 5, the red part 62 of the alarm indicator stopper 6 is covered by the hollow upper end 52 of the buoy 5. However, the appearance of the yellow portion 63 indicates that the tire pressure has been reduced, but this is not the time to refill the tires.

FIG. 6 shows a case where the tire pressure is insufficient, and when the spring 9 pushes down the buoy 5 again, the yellow and red portions 62 and 63 of the alarm display cap 6 at this time are lowered. Since both are not covered by the hollow upper end 52 of the buoy 5, the user can visually see the yellow and red of the alarm display cap 6. This indicates that the tire is under pressure and needs to be replenished immediately for safe driving.

Therefore, in the embodiment of the present invention, it is only necessary to visually observe whether the yellow, red portions 62, 63 of the alarm display cap 6 appear. When both colors appear, you need to refill the air immediately, so you can get a safety alert.

1. Troublesome inspection and surveying work can be skipped before driving and the tire pressure cover is normally observed by observing the color change of the tire pressure cover.

2. It raises the safety of the user by calling the user's attention that the tire is not damaged by the external force and lacking the tire pressure.

3. It can be used even in bad weather conditions, and it is waterproof and corrosion resistant.
