Interphone for security management of community

Abstract

The invention relates to an interphone for security management of a community. The interphone comprises an antenna, rotary knobs, a loudspeaker, a button, a body, a fixing mechanism, and an extensionand retraction mechanism, wherein the fixing mechanism comprises a first driving assembly, a cylinder, a pipeline, a piston, a first transmission rod, a casing, a sucking disc and an air bag; and theextension and retraction mechanism comprises a limiting assembly, a second driving assembly, two first through holes, a base pipe, two first springs, and a first support rod. The interphone for the security management of the community has the advantages that through the fixing mechanism, a user can fix the interphone on a table when the interphone is not used, so that the phenomenon that the useraccidentally touches the interphone when doing office work at the table and the interphone therefore drops and is damaged is avoided, and unnecessary losses are further reduced; and moreover, antennaextension and retraction functions are achieved through the extension and retraction mechanism, so that the antenna can be prevented from being broken due to body movements of the user when the interphone is fixed on clothes of the user, and the practicality of the interphone is improved.

Description

Technical field [0001] The invention relates to the field of security equipment, in particular to a walkie-talkie used for community security management.

Problems solved by technology

[0003] Among them, the walkie-talkie is a kind of security equipment. When the walkie-talkie is placed on the desktop, because it is not effectively fixed, if people accidentally touch the walkie-talkie during the subsequent office work, it is easy to cause the walkie-talkie to fall from the table. Not only that, when people use the walkie-talkie outdoors, they are used to pinning the walkie-talkie to their bodies. During the process of human body movement, it is easy to squeeze the walkie-talkie, thus breaking the antenna of the walkie-talkie and reducing The practicality of the walkie-talkie
