Description

Technical Field

[0001] The utility model relates to the technical field of an intercom host, in particular to a platform for placing an intercom host. Background Art

[0002] Existing intercom hosts are all installed near the unit door, which are complex in structure, troublesome to install, and not conducive to inspection and maintenance. Even when the unit door wall is a glass curtain wall, it is impossible to install it on the wall. During the installation of the intercom host, a platform for placing the intercom host is required for installation;

[0003] Announcement No. CN203868644U discloses a platform for placing an intercom host, comprising a supporting body and a base, wherein the upper end of the supporting body is fixedly provided with the fixing bracket, and the lower end of the supporting body is fixedly provided on the base; the angle between the bottom surface of the fixing bracket and the horizontal plane is 55°-70°; the supporting body is provided with an intercom host line channel, and the base is provided with a through hole connected with the intercom host line channel;

[0004] There may be two problems when using it. First, the device is installed close to the gate, making it completely open-air. The sunlight is dazzling when people are operating it, making it inconvenient to operate. If shielding is required, it needs to be installed separately, making the installation inconvenient. Second, if there is a shielding on the outside, its height is mostly fixed, and it is difficult to use in a specific area. Therefore, after the platform is completed, it is necessary to customize the outside shielding, which makes the cost higher. Therefore, we propose a platform for placing the intercom host.
