Abstract

The invention discloses a multipurpose security doorbell which comprises a connecting sleeve, the inner wall of the connecting sleeve is in threaded connection with a connecting cylinder; an inner machine is fixed on the circumferential outer wall of the connecting cylinder; a plurality of ringing cavities are formed in the inner part of the inner machine; a ringing mechanism is arranged in each ringing cavity; an outer machine is fixed to the outer wall of the connecting sleeve, a piezoelectric block is fixed to the inner wall of the outer machine, a pressing plate is connected to the inner wall of the outer machine through a reset spring, a lens set is arranged in the connecting sleeve, a wiring groove is formed in the side wall of the connecting sleeve in a penetrating mode, and a powerconnection block is connected to the inner wall of the wiring groove through a pressing spring. The door viewer has the advantages that the lens group is arranged in the connecting sleeve, and the connecting cylinder is also hollow, so that the indoor space can be directly observed outdoors through the connecting sleeve and the connecting cylinder, the function of the door viewer is completed, the doorbell and the door viewer are effectively combined, the occupied area of the doorbell and the door viewer is reduced, and the function of the whole equipment is improved.

Description

technical field [0001] The invention relates to the technical field of security doorbells, in particular to a multi-purpose security doorbell. Background technique [0002] Doorbells are divided into wired doorbells and wireless doorbells. Active wireless doorbells are doorbells that are often seen in daily life. The signal receiver receives this wireless signal, and then rings; the wired doorbell is the doorbell whose signal transmission is connected through the line; [0003] The wireless doorbell relies on wireless signal transmission between the transmitter and receiver, so the signal transmission is not stable enough, and false ringing may occur, while the limited doorbell has troublesome wiring, and may need to cut walls, etc., so it is inconvenient to install, and the existing All doorbells need additional power supply, and will not work when the power is off, and the overall use is inconvenient. Therefore, there is an urgent need for a doorbell with stable signal tr...
