Abstract

The invention discloses a doorbell, which comprises a shell with perforations on the surface, a motor compartment and a ringing compartment inside the shell, a motor is fixedly installed in the motor compartment, and a mandrel parallel to the main shaft of the motor is arranged in the ringing compartment. The two ends of the mandrel are respectively fixed on the two opposite side walls of the ring chamber. The middle of the mandrel is large and the two ends are small. Two torsion springs arranged symmetrically on the mandrel are sleeved on the mandrel, and half of the torsion spring is fixedly grounded It is tightly sleeved on the larger shaft section in the middle of the mandrel, and the other half is not fixedly connected with the smaller shaft section of the mandrel, and the end of the half torsion spring is fixedly connected with the rotating plate rotatably sleeved on the mandrel. The side of the plate facing the motor shaft is connected with a vibrating reed; a pair of connecting rods perpendicular to the main shaft are fixed on the shaft, a spring is installed at the end of the connecting rod, and a steel ball is fixed at the end of the spring away from the connecting rod. When the motor rotates , the steel ball can touch the vibrating reed. The doorbell has reliable structure, low failure rate, and can effectively avoid excessively long reverberation.

Description

Technical field [0001] The invention belongs to the technical field of doorbells, and particularly relates to a mechanical doorbell. Background technique [0002] At present, the types of doorbells mainly include mechanical and electronic doorbells. The installation conditions of mechanical doorbells, such as temperature and humidity, are lower than those of electronic ones. The current mechanical doorbell has unstable structure, high failure rate, poor sound effect, and opening Later, when the power is stopped, the residual sound is longer and cannot be stopped in a short time. Summary of the invention [0003] The object of the present invention is to provide a doorbell, which effectively solves the technical problems of the existing mechanical doorbells of unstable structure, high failure rate and long reverberation. [0004] The technical scheme of the present invention is as follows: [0005] A doorbell includes a housing with a perforation on the surface, a motor compartment a...
