Son device of interphone

Abstract

A talkback door bell handset apparatus is provided. Name brand and the like mounting parts are formed on the front upper part of the outer shell of the talkback door bell handset apparatus, and when the outer shell is long, even mounting screw part is less, the outer shell can also be tightly mounted on the mounting part to avoid vibrating with the hand set to generate noise. The handset apparatus has a talkback door bell handset received in an outer box made of synthetic resin, and a long rectangle outer shell made of synthetic resin for forming circumferential walls extending from the periphery of a front panel to the rear part, wherein the rear surfaces of the circumferential walls are in the same plane. In a talkback door bell handset receiving part at the lower part of the back side of the outer shell, the handset can be supported by an upper elastic supporting part in a free mounting or dismounting mode when the handset is supported by a lower supporting part. The upside of the receiving part is provided with upper side fixing convex parts extending from the front panel to the backside and lower side fixing convex parts shorter than the upper side fixing convex parts. When the upper side fixing convex parts are fastened by screws, the lower side fixing convex parts are fastened by screws, and the circumferential walls of the receiving part are mounted on the mounting parts by the elastic force of the outer shell in a mode of pressing the mounting part.

Description

technical field [0001] The present invention relates to an intercom doorbell sub-machine device containing an intercom doorbell sub-machine, in particular to an intercom doorbell sub-machine device suitable for multifamily housing (Multifamily Housing), the intercom doorbell sub-machine has a The sounding element and the camera are connected electromechanically to the intercom doorbell mother, and are accommodated in a synthetic resin outer box. Background technique [0002] As an intercom doorbell machine with a camera, there has been an intercom doorbell machine with the following structure: the circuit board 5 is fixed on the part corresponding to the mounting plate in the housing 8 by screws, and the monitor camera 2 is installed on the circuit board 5 , and the claws on the upper end of the peripheral wall of the housing 8 are engaged with the mounting plate 18 at the porch or the like (refer to Patent Document 1: JP Unexamined Publication No. Hei 9-18862). [0003] Th...

Problems solved by technology

[0005] In this case, in the case of installing the intercom doorbell unit housed in a synthetic resin outer case and unitized into the housing, the number of parts can be reduced and the number of parts can be reduced by using the mounting structure without screws. In the case of assembly, if there is some installation slack between the door intercom and the casing, or between the casing and the mounting part on the back, the intercom doorbell may be damaged due to vibrations during sounding, etc. Vibration, which is transmitted to the housing, creates continuous noise problems
