Description

Safety blind road floor tile

Technical Field

The invention belongs to the field of blind person guiding devices, and particularly relates to a safety blind way floor tile.

Background

The blind road brick is a convenient road facility for the blind to go out safely. Generally, the blind person walking guide brick is paved by three types of bricks, namely a strip-shaped direction guide brick which guides the blind person to walk forward; one is a prompting brick with round points to prompt the blind to have an obstacle in front; the other type is a blind road danger warning guide road brick with large round points.

Most of the existing blind road floor tiles with round points are simple in structure and only can play a role in simple guiding and prompting. When the blind walks, the route inevitably generates slight deviation, the blind cannot sense the slight deviation at the moment, and the slight deviation can cause large deviation in the accumulation process of a long road section, so that the blind deviates from a blind road, and at the moment, the blind needs to slowly explore and walk back to the blind road, which is troublesome, dangerous and has high possibility of accidents; in addition, although the existing blind road prompting brick can remind the blind person of turning on a turning road section, the blind person cannot know the left turning or right turning condition in the next step, and the blind person still needs to select the left turning or right turning under the corner feeling of further exploration of the blind roller, so that the time is wasted, and the blind person is confused about the unpredictable condition.

To this end, we propose a safety blind sidewalk floor tile to solve the above problems.

Disclosure of Invention

The invention aims to provide a safe blind road floor tile capable of giving out an alarm and reminding blind people of turning directions, aiming at the problem that the blind road floor tile cannot play a good warning and reminding role.

in order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides a safe blind road ceramic tile, includes the casing, sealing sliding connection has the brick body in the casing, be equipped with the vibrations chamber between casing and the brick body, through spring fixedly connected with bell on the lateral wall in vibrations chamber, the brick body inlays at bell relevant position and is equipped with permanent magnetism piece, the bell is made by magnetic material, bell and permanent magnetism piece heteropolar attract mutually, be equipped with four spouts in the brick body, the spout passes through air vent and vibrations chamber intercommunication, there is protruding piece through stop gear sealing sliding connection in the spout, the upper end of protruding piece extends to the external setting of brick.

In the safety blind road floor tile, a plurality of balls are embedded in the inner bottom surface of the shell in a rolling manner, the tile body is connected with the balls in a rolling manner, two sealing blocks are fixedly connected to the lower bottom surface of the tile body, and the sealing blocks are connected with the inner side wall of the shell in a sliding and sealing manner.

In the safety blind road floor tile, the sliding grooves in the middle of the tile body are communicated with the outside air, and the sliding grooves on two sides of the tile body are respectively communicated with the vibration cavities on two sides.

In the above safety blind sidewalk floor tile, the limiting mechanism includes a limiting ring fixedly sleeved outside the protruding block, a limiting groove for accommodating the limiting ring is arranged on the side wall of the sliding groove, and the limiting ring is slidably connected with the limiting groove.

In the safety blind sidewalk floor tile, the bottom surface of the sliding groove is fixedly connected with a threaded rod, and the upper end of the threaded rod extends into the convex block and is connected with the convex block through threads.

Compared with the prior art, the safety blind road floor tile has the advantages that:

1. According to the invention, the convex blocks are arranged, when the blind person steps on the convex blocks in the middle area of the brick body, the convex blocks move downwards to achieve a good buffering effect, and when the blind person steps on the convex blocks on one side of the brick body, the air in the sliding grooves corresponding to the convex blocks is extruded into the vibration cavities, so that the brick body slides in the shell, and a more obvious tactile prompt is given to the blind person to prompt the blind person to correct the advancing route.

2. According to the invention, the rattle is arranged, when the brick body slides in the shell, the permanent magnet blocks move away from the rattle, the rattle moves along with the permanent magnet blocks under the action of magnetic force, when the pulling force of the spring is greater than the attraction force of the permanent magnet blocks, the rattle moves to the limit position, at the moment, under the action of elastic force, the spring pulls the rattle to move to the initial position and drives the rattle to vibrate, the rattle gives out an alarm sound, the blind is further reminded to correct the route, and the blind is prevented from deviating from the blind road to cause dangerous accidents.

3. According to the blind guiding device, the threaded rod is arranged, when the blind treads on the convex block, the convex block moves towards the sliding groove and rotates towards the turning direction of the road, and the blind can judge the turning direction of the road ahead according to the rotating direction of the convex block, so that a good guiding effect is achieved.
