Anti-theft door with silencing function

Abstract

The invention discloses an anti-theft door with a silencing function. The anti-theft door comprises a door body, wherein the center of the door body is rotatably connected with a rotating column; therotating column is rotatably connected with a rotating wheel through a coil spring; the cross section of the rotating wheel is of an oval shape; one end of the rotating wheel is fixedly connected witha permanent magnet; the rotating column is provided with a rotating bell; the rotating bell is sealed with a sound receiving box; a sound receiving tube is communicated with the sound receiving box in an up-down symmetrical mode; one end, away from the sound receiving box, of the sound receiving tube is connected with a sound division tube; and the diameter, from one end of the sound receiving box to one end of the sound division tube, of the sound receiving tube is smaller and smaller. Through the interaction of the sound receiving box, the silencing layer and other structures, the volume can enter the outer side to play a silencing effect, so that when the ringtone is ringing out, the volume cannot be transmitted out, a neighbor is not disturbed, and the noise pollution is reduced; andmeanwhile, people in a house can hear the ringtone more obviously and clearly by virtue of sound amplification holes.
