[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figures 1 to 5 The utility model provides a technical solution: a building access control intercom device, including an intercom body 1 and a protective shell 2, the intercom body 1 is slidably matched in the protective shell 2, a door panel 10 is slidably matched on one side of the protective shell 2, an upper top plate 6 is installed on the top of the protective shell 2, a lower bottom plate 7 is installed on the bottom of the protective shell 2, a plurality of telescopic rods 9 are installed between the lower bottom plate 7 and the upper top plate 6, the lower bottom plate 7 is fixedly connected to the intercom body 1, the lower bottom plate 7 corresponds to the protective shell 2, and a pull rope 8 is fixed on the lower side of the lower bottom plate 7.

[0021] In this embodiment, a plurality of first slide grooves 3 are provided on one side of the protective shell 2, a plurality of first sliders 5 are fixed on the door panel 10, the first sliders 5 correspond to the first slide grooves 3, a plurality of second slide grooves 4 are provided in the protective shell 2, the telescopic rod 9 is located in the second slide groove 4, a plurality of card slots are provided at the bottom of the protective shell 2, the card slots are connected with the second slide grooves 4, and a display screen 11, a camera 12 and a plurality of buttons 13 are installed on the intercom body 1.

[0022] Specifically, when the intercom body 1 needs to be used, the door panel 10 only needs to be slid upward to expose the display screen 11, the camera 12 and the multiple buttons 13, and the intercom body 1 can be used. When the intercom body 1 is not needed, the door panel 10 is slid downward so that the door panel 10 and the protective shell 2 form a sealed structure, thereby protecting the intercom body 1.

[0023] A plurality of card blocks 14 are fixed on the lower base plate 7, and the card blocks 14 correspond to the card slots. The lower base plate 7 is fixedly connected to the intercom body 1 by bolts, the upper top plate 6 is fixedly connected to the protective shell 2 by bolts, one end of the telescopic rod 9 is fixedly connected to the upper top plate 6 by bolts, and the other end of the telescopic rod 9 is fixedly connected to the lower base plate 7 by bolts.

[0024] Specifically, when the height of the intercom body 1 needs to be changed, the pull rope 8 is pulled downward, so that the pull rope 8 pulls the lower base plate 7 downward, thereby causing the card block 14 to lose the card connection relationship with the card slot, and the lower base plate 7 drives the intercom body 1 to slide downward, and the telescopic rod 9 is lengthened, so that the position of the intercom body 1 can be changed, thereby making the intercom body 1 suitable for use by children of shorter height.

[0025] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
