Detailed Description

In order to make the above features and advantages of the present utility model more comprehensible, embodiments accompanied with figures are described in detail below.

As shown in fig. 1 to 3, the present embodiment provides a pressure-resistant and fall-resistant intercom, which includes a front housing 1, a rear housing 2, a control output assembly 3, and an elastic sleeve 5.

The front shell 1 is provided with a containing cavity 11 with an opening facing one side, two corresponding inner side walls of the containing cavity 11 of the front shell 1 are provided with necking convex strips 12, the front shell 1 is provided with an audio playing area and a button area, and a limiting column 13 is arranged in the containing cavity 11.

The back casing 2 forms the installation cavity 21 and opening towards holding chamber 11 one side, and two lateral walls that back casing 2 and opening correspond are formed with spacing sand grip 22, and spacing sand grip 22 of back casing 2 is located holding chamber 11 opening part and offsets with the throat sand grip 12 and push up, and back casing 2 and preceding casing 1 cooperation form the inner chamber, and the maximum width is greater than the width of preceding casing 1 after back casing 2 and preceding casing 1 cooperation, and back casing 2 passes through the deformation card and goes into holding intracavity 11. The concrete installation mode is as follows: the spacing sand grip 22 of back casing 2 one side is blocked in holding chamber 11 and is supported with the throat sand grip 12 in the top earlier, then the spacing sand grip 22 of back casing 2 opposite side is crowded into holding chamber 11 through the mode of deformation and is accomplished the installation, can not take place the separation in the use through above-mentioned setting front and back casing 2.

An elastic sleeve 5 is connected between the rear shell 2 and the bottom surface of the accommodating cavity 11, specifically, the elastic sleeve 5 is sleeved on a limiting column 13, the limiting column 13 is smaller than the depth of the accommodating cavity 11, and the limiting column 13 is used for limiting the movement of the elastic sleeve 5, and the elastic sleeve 5 is a spring.

The control output assembly 3 comprises an integrated circuit board, in particular a PCB motherboard, and a battery. The control output assembly 3 is installed between the rear shell 2 and the front shell 1, in this scheme, the control assembly is installed in the installation cavity 21 on the rear shell 2, be equipped with buffer layer 4 between control output assembly 3 and the installation cavity 21, buffer layer 4 is the silica gel pad, the blotter passes through gluing or screw connection's mode to be fixed on the rear shell 2, control output assembly 3 passes through screw connection's mode and is connected with buffer layer 4, specifically, the screw is connected with rear shell 2 from the screw in passes buffer layer 4 on the control output assembly 3, when the intercom receives the impact, control output assembly 3 can be unloaded most effort under buffer layer 4's effect.
