Technical Field

The invention belongs to the field of automobile tire burst emergency devices, and particularly relates to a supporting band anti-drop blocking supporting bead and a tire burst 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. The prior art discloses a tire burst emergency safety device, which can limit the position of a tire through a support fastened on a wheel hub, and can prevent the tire from being separated after the tire burst so as to avoid out of control.

The supporting strap is generally made of metal, two ends of the supporting strap are provided with bending tongues which are bent inwards to form a bending part, and two or more bending parts are connected through a connecting piece to realize fastening. However, the inward bending structures at the two ends of the support belt of the tire burst safety emergency device are in contact with the hub, and the bending parts bear huge pulling force and stamping force during tire burst, so that the support belt may be straightened or flattened, and the support belt is separated from failure.

Therefore, there is a high necessity for a blocking support member capable of protecting the inward bent structures at both ends of the support band from a deformation tendency in the event of a tire burst, so as to prevent the support band from being separated from the support band.

Disclosure of Invention

The invention aims to provide a blocking support piece which can protect inward bending structures at two ends of a support band from generating deformation tendency when a tire is punctured so as to prevent the support band from being separated from the support band. The invention comprises the following steps:

the utility model provides a support and support area anticreep jam support pearl, includes the body, the body has and is used for holding the recess that supports the area tongue of buckling, the recess will the body divide into and is used for the gasket to support the anti-skidding anticreep portion of area between the area tongue of buckling and wheel hub and is used for filling the supporting part that supports the area kink.

Further, the anti-slip and anti-drop part is provided with an opening for reducing the elasticity of the anti-slip and anti-drop part.

Furthermore, the opening is U-shaped and correspondingly forms a U-shaped elastic sheet, a protrusion is arranged on the side, away from the hub, of the U-shaped elastic sheet, an inclination angle is arranged on the top surface of the protrusion, and a limiting hole is preset in the bending tongue of the supporting belt; the limiting hole is matched with the bulge and used for limiting the installation between the blocking supporting bead and the bending tongue of the supporting belt.

Furthermore, the supporting part is provided with a through limiting groove, and the limiting groove is used for placing a connecting piece between the supporting belt and the other supporting belt.

Furthermore, the blocking support beads are made of elastic materials.

Furthermore, the material of the blocking support beads is polypropylene.

Further, the body is wedge-shaped.

An emergency safety device for tyre burst comprising a blocking support bead as claimed in any one of the preceding claims.

The invention has the following beneficial effects:

the blocking support bead provided by the invention can protect the inward bending structures at the two ends of the support belt from generating deformation tendency when the tire bursts, and prevent the support belt from loosening or separating from the other support belt, so that the emergency device for tire burst has a protection function all the time.

The blocking support beads provided by the invention can support the inward bending structures at the two ends of the support belt, and prevent the support belt from deforming to cause uneven stress when a tire bursts.

The blocking support bead is simple in structure and convenient to install.

The blocking support bead provided by the invention can be used for processing electronic products such as: tire pressure detection, GPS positioning, a thermometer, an oil tank, a loosening alarm clock or a tire burst alarm and the like are placed in the blocking support beads, so that electronic products can be protected from being crushed; meanwhile, joints on two sides of the steel belt are idle at ordinary times, and resonance occurs during running of the vehicle, so that the blocking support beads provided by the invention can absorb the resonance.
