Description

High elasticity buffering angle bead

Technical Field

The utility model belongs to the technical field of the angle bead, refer in particular to a high elasticity buffering angle bead.

Background

The internal and external corners are one of building structures, and the internal corners refer to recessed wall corners, such as included angles between the top surface and surrounding walls; the external corner refers to a protruding wall corner, such as an included angle formed by two walls at a turning part of a walkway.

The external corner is very easily scratched or collided due to the design of the protruding wall surface, so that the external corner is damaged, the integrity and the attractiveness of the wall surface are affected, the external corner is collided under the action of external force to form a notch, generally, in order to protect the external corner, a protective device such as a corner protection strip is installed at the external corner of the wall body, and the impact resistance of the external corner is enhanced. Due to the design that the external corner protrudes out of the wall surface, the external corner part is easily scratched or collided to be damaged, and the external corner is protected by the corner protector; however, the conventional corner protector has poor annular performance, so that the wall body is damaged.

SUMMERY OF THE UTILITY MODEL

To the deficiency that prior art exists, the utility model aims to provide a simple structure and high elasticity buffering's angle bead.

In order to achieve the above purpose, the utility model provides a following technical scheme: a high-elasticity buffering angle bead comprises an outer surface layer and an angle bead body, wherein the angle bead body comprises an outer supporting layer, a damping middle layer, a soft rubber layer and an EPDM supporting layer which are sequentially stacked from outside to inside, and the layers are fixedly connected through an adhesive.

By adopting the technical scheme, the outer supporting layer is used for adhering the outer surface layer, the damping middle layer can play a certain damping effect, and the buffering and damping performance of the corner protector can be further ensured by the cooperation of the soft rubber layer and the EPDM supporting layer.

The utility model discloses further set up to: a plurality of high-elastic ETPU particles which are uniformly distributed are embedded in the soft rubber layer.

Through adopting foretell technical scheme, the flexible glue film is embedded to have a plurality of evenly distributed's high-elastic ETPU granule to can further ensure the buffering effect of flexible glue film.

The utility model discloses further set up to: the outer supporting layer is embedded with a plurality of arc-shaped elastic sheets which are longitudinally distributed and have arc-shaped sections, and the openings of the arc-shaped elastic sheets face the damping middle layer.

Through adopting foretell technical scheme, set up the arc shell fragment in outer supporting layer to can guarantee the effect of the elastic buffer of outer supporting layer, with the practical life who improves the angle bead.

The utility model discloses further set up to: the outer surface of the EPDM supporting layer is provided with a latticed receiving groove.

Through adopting foretell technical scheme, the surface of EPDM supporting layer is formed with and is latticed accepting the groove to for the angle bead provides certain deformation clearance, thereby reduce the fracture probability of EPDM supporting layer appearance.
