Abstract

The utility model discloses a bead pad arranged on a tire emergency safety device, belonging to the field of automobile tire burst emergency devices. After the plastic cushion bead is arranged on the supporting belt, when an accident occurs and the supporting belt of the emergency device rubs with the rim, the failure of the emergency mounting device caused by tire burst after skidding can be effectively prevented.

Description

Pad bead mounted on tire emergency safety device

Technical Field

The utility model belongs to the field of automobile tire burst emergency devices, and particularly relates to a bead mounted on a tire emergency safety device.

Background

When the tire pressure of the vehicle tire is lower than a standard value or after air leakage is caused by tire damage, the friction between the deflated tire and the ground is multiplied, the tire temperature is increased rapidly, the tire is softened, and the strength is reduced rapidly, in this case, if the vehicle runs at high speed, the tire burst can be caused; if a certain tire of the vehicle is punctured, the vehicle can be deviated, if a driver cannot correctly deal with the tire, the vehicle can be overturned to collide with a guardrail to cause danger, and even the vehicle can collide with a vehicle in the same direction or a vehicle in the opposite direction, so that great personal injury or property loss is caused.

At present, a tire burst emergency safety device is mounted on a hub of a tire to prevent the tire from bursting. In order to protect the hub from being damaged when a tire burst accident occurs, a bead pad is arranged between a support belt of the tire burst emergency device and the hub. However, after the bead gasket in the prior art is installed on the supporting belt, when an accident occurs and the supporting belt of the emergency device rubs against the rim, the bead gasket in the prior art cannot effectively prevent the supporting belt from slipping relative to the hub, which leads to the failure of the emergency safety device for tire burst.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model adopts the following technical scheme:

the utility model provides an install and fill up pearl on emergent safety device of tire, it installs on the mounting hole that supports the area to fill up the pearl, it includes fills up the pearl body to fill up the pearl, it is round platform structure to fill up the pearl body, the major diameter end that fills up the pearl body is provided with the boss, the boss embedding support the mounting hole of area in.

Further, the axis of the boss coincides with the axis of the bead body.

Further, an axially arranged first cavity is formed in the boss and extends to the bead body.

Further, the small diameter end of the bead body has a second cavity disposed axially.

Further, the first cavity and the second cavity are independent of each other.

Further, the first cavity and the second cavity are arranged in a manner of being overlapped with the axis of the pad bead body.

Furthermore, a groove is arranged at the joint between the boss and the large-diameter end face of the bead pad body, and the axis of the groove is overlapped with the axis of the boss.

Further, the bead body and the boss are integrally formed.

Furthermore, the pad beads are made of plastic materials.

The utility model has the following beneficial effects:

after the plastic cushion bead is arranged on the supporting belt, when an accident occurs, the supporting belt of the emergency device rubs against the hub, and the tire burst emergency mounting device can be effectively prevented from losing efficacy after slipping.

Detailed Description

In the prior art, a tire emergency safety device includes support belts arranged in pairs with bead mounting holes.

Example 1

Referring to fig. 1-4, a pad bead installed on a tire emergency safety device is installed on a mounting hole of a support belt, and comprises a pad bead body 1, wherein the pad bead body 1 is in a circular truncated cone structure, a boss 2 is arranged at the large-diameter end of the pad bead body 1, and the boss 2 is embedded in the mounting hole of the support belt.

In the present embodiment, the axis of the boss 2 coincides with the axis of the bead body 1.

In the present embodiment, the boss 2 has a first cavity 3 disposed axially therein, and the first cavity 3 extends to the bead body 1.

The small diameter end of the bead body 1 has an axially disposed second cavity 4.

In this embodiment, the first cavity 3 and the second cavity 4 are independent from each other, and the first cavity 3 and the second cavity 4 are disposed in coincidence with the axis of the bead body 1.

In the embodiment, a groove 5 is arranged at the joint between the boss 2 and the large-diameter end face of the bead body 1, and the axis of the groove 5 is coincident with the axis of the boss 2.

In the present embodiment, the bead body 1 is integrally formed with the boss 2.

In this embodiment, the bead is made of plastic.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solutions of the present invention can be made by those skilled in the art without departing from the spirit of the present invention, and the technical solutions of the present invention are within the scope of the present invention defined by the claims.
