Detailed Description

In order to further understand the objects, structures, features and functions of the present invention, the following embodiments are described in detail.

Referring to fig. 1, fig. 1 is a schematic view of an overall structure of an anti-falling glass bead of the present invention.

As shown in fig. 1, the utility model discloses an anti-drop's glass bead, include by last first section 1, second section 2 and the third section 3 that connects gradually from top to bottom, the external diameter of first section 1 and third section 3 is greater than the external diameter of second section 2, and first section 1 is spherical with third section 3.

In one embodiment, the glass beads are of a three-section type but are of an integrally formed structure, so that the outer surfaces of the glass beads are smooth, and the reflection effect of the outer surfaces of the glass beads can be guaranteed. The utility model discloses a glass bead divide into first section 1, second section 2 and third section 3, the external diameter of first section 1 and third section 3 is greater than second section 2, and 2 transitional coupling of second section are between first section 1 and third section 3, thereby make glass bead form the big little structure in the middle of both ends, so inlay when the basal layer of reflective membrane is gone into to the glass bead, basic unit's material can directly wrap up and cover the 2 outsides of second section of glass bead, only first section 1 or third section 3 are located the basic unit top and are used for the reflection of light, this kind of structure, can utilize basic unit's material well parcel to live glass bead, the tip external diameter that utilizes glass bead is greater than the structural feature of 2 external diameters of second section, can make firmly fix glass bead, make glass bead can't follow the basic unit and drop, thereby glass bead's fixed stability has been improved. In addition, the first section 1 and the third section 3 are both spherical, so that the first section 1 and the third section 3 are both ensured to have good reflection effects, the reflection range is large enough, the reflected light can be seen from all angles, and the reflection effect of the glass beads cannot be influenced due to the special structure of the glass beads.

Preferably, the first section 1 and the third section 3 have the same structure, so that when the glass beads are fixed, one end of the glass beads can be arbitrarily selected to be fixed in the substrate, and the reflection effects of the two ends of the glass beads are ensured to be the same.

Preferably, first section 1 and third section 3 are the ellipse sphere shape, and the first section 1 and the third section 3 of ellipse sphere shape make the anticreep effect after the glass microballon fixes in the base layer better, and simultaneously for the sphere, the reflection of light area is bigger, and effectual reverberation is more, and the radian bending of oval sphere is comparatively gentle for the sphere, so can make the reverberation concentrate a little relatively to make the reverberation intensity reinforcing, so make the reverberation propagation effect better.

Preferably, the second segment 2 is in the shape of a truncated cone with an inwardly recessed middle. The inside sunken second section 2 makes the external diameter at 2 middle parts of second section more thin to make the difference between the minimum external diameter of second section 2 and the biggest external diameter of first section 1 and third section 3 bigger, thereby make the fixed effect of glass microballon in the basement of reflective membrane better, can further prevent that the glass microballon from droing.

Preferably, the glass beads are hollow structures 4, which can effectively reduce the particle weight of the glass beads, thereby reducing the weight of the reflective film.

Preferably, the outer sides of the glass beads are plated with the anti-corrosion layer 5, and the reflective film is exposed outdoors for a long time and subjected to wind, rain and sun exposure, so that the anti-corrosion layer 5 can effectively protect the glass beads and prevent the glass beads from being corroded to influence the reflection effect. Further, the anti-corrosion layer 5 is a transparent material so as not to affect the reflection effect of the glass beads.

The utility model discloses when specifically using, directly inlay the dress in the basic unit of reflective membrane with first section 1 or third section 3 of glass bead, so can prevent the slope of glass bead, and first section 1 is the same with 3 structures of third section, need not confirm the direction, can select one end embedding wantonly, the production of being convenient for is arranged.
