Embodiment 1
[0020] Such as Figure 1-2 As shown, a strip-shaped direction guide brick includes a brick body 1, and four strip-shaped grooves 2 arranged side by side at equal distances are arranged in the brick body 1. The bottoms of the four strip-shaped grooves 2 are all communicated through vent holes 3, and the vent holes 3 There is a whistle tube 4 inside, and the whistle tube 4 is located between the two bar-shaped grooves 2 in the middle. The bar-shaped groove 2 is sealed and slidably connected with a guiding protrusion 5 through a limit mechanism. When a blind person steps on the middle two bars of the brick body 1 When the leading raised block 5 is on, the whistle tube 4 does not make a sound.

Embodiment 2
[0024] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the volume of the two strip grooves 2 located in the middle is smaller than the volume of the two strip grooves 2 located on both sides, when the two strip grooves 2 on one side of the brick body 1 When the guide bumps 5 are stepped on at the same time, the guide bumps 5 close to the center of the brick body 1 first reach the bottom of the strip groove 2, and the air holes 3 are closed, and the guide bumps 5 at the center of the brick body 1 Unable to continue descending.
[0025] When the blind walks on the blind road, a sole of the blind person can step on two of them on the two leading raised blocks 5 in the brick body 1, and when the blind stepped on the two leading raised blocks 5 of B and C, the sentinel tube 4 will not vocalize;
