Description

Technical Field

[0001] The utility model belongs to the technical field of floor tiles and relates to a blind road brick with long afterglow luminous performance. Background Art

[0002] With the continuous development of long-lasting glow material preparation technology, it has gradually become a new type of new energy luminescent material. It has advantages such as long luminescence lifetime and easy structural modification. Its excellent processability, thermal stability, flexibility, and amorphous state have also led to its widespread application in lighting displays, biosensing, data encryption, information anti-counterfeiting, optical detection, and other fields. Blind paths are road facilities designed to assist the blind. The bricks used in these paths are mostly ordinary colors such as yellow and gray. While relatively easy to identify during the day, they are less visible at night, making them easily occupied and hindering their travel.

[0003] Applying fluorescent materials to paving bricks can improve their visibility at night or on cloudy days. This method has been reported in numerous patent documents. For example, CN2486316Y discloses a long-lasting luminous plate-shaped material. A layer of luminescent material that emits a long-lasting luminous glow is attached to a man-made substrate layer, with an adhesive used to bond the two together. The luminescent material layer is composed of fluorescent particles melted into a base material, or of fluorescent particles and base material particles bonded together with an adhesive. CN218540275U discloses a guide tile for building decoration, comprising a brick body, wherein a transparent cover is embedded in the upper end of the brick body, a protrusion is connected to the upper end of the brick body, a through hole is provided at the connection between the transparent cover and the protrusion, the lower side of the transparent cover is located on the upper end surface of the brick body and is coated with a luminous paint layer, the lower end of the transparent cover is connected to a pin block, and an embedding groove is provided at the connection between the brick body and the pin block; by arranging the luminous paint layer, the transparent cover, the pin block and the embedding groove in the guide tile for building decoration, after the luminous paint layer is dried, the transparent cover is covered on the luminous paint layer to protect it and prevent the luminous paint layer from being worn. The luminous paint emits light at night, which can remind people that this is a blind path and cannot be occupied, thereby effectively improving the recognition of the guide brick at night.

[0004] However, while existing fluorescent paving bricks can produce fluorescence, improving nighttime visibility, they lack a guiding function. This is especially true for blind paving bricks, which require clear identification, not only of their location but also of whether they are tactile pathways. Furthermore, existing tactile paving bricks are often flat around their edges, making them unstable. Summary of the Invention

[0005] In view of the above-mentioned state of the prior art, the purpose of this utility model is to provide a long-lasting luminous paving brick for the blind. This paving brick not only improves nighttime visibility, prevents the blind path from being occupied, and brings convenience to blind people's travel, but also adds a plug-in body on the side of the paving brick, which improves the stability of the blind path and makes it smoother.

[0006] The technical solution for achieving the above objectives can be summarized as follows:

[0007] A blind paving brick with long afterglow luminous performance includes a blind paving brick body, a blind paving brick protrusion is provided on the upper surface of the blind paving brick body, a paint groove is provided in the blind paving brick protrusion, a long afterglow paint layer is provided in the paint groove, a plug-in block is provided on the side of the blind paving brick body, and a groove adapted to the plug-in block is provided on the side of the blind paving brick body opposite to the plug-in block.

[0014] According to the present invention, preferably, the plug-in block is a cylindrical structure, a square column structure or a triangular prism structure.

[0015] Beneficial effects of the utility model:

[0016] 1. This utility model creates a coating groove in the raised area of ​​the blind paving bricks, and then coats the groove with a long-lasting afterglow coating. This coating layer allows the road to continue luminous at night after storing energy during the day.
