Detailed Implementation

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] like Figs. 1-2 As shown, a waterproof walkie-talkie with buttons 105 includes a walkie-talkie housing 101, a display screen 102 disposed on the walkie-talkie housing 101, a walkie-talkie port 103 disposed on the walkie-talkie housing 101, and a button slot 104 formed on the walkie-talkie housing 101. The walkie-talkie housing 101 and the button slot 104 are provided with a plurality of buttons 105 for preventing fluid from seeping in through a sealing device.

[0020] In order to prevent rain from falling into the shell from the button slot 104, the sealing device comprises: a sealing pad 106 arranged in the intercom shell 101, the edge part of the side in contact with the intercom shell 101 is fixedly connected to the intercom shell 101, the button 105 is arranged on the upper side of the sealing pad 106, and the button 105 and the button slot 104 are further provided with a seepage prevention device for further enhancing the sealing; the intercom shell 101 is provided with a PCB board 116, the bottom of the sealing pad 106 is in contact with the contact 117 on the PCB board 116 for pressing the contact 117; the detailed structure inside the intercom is well known, and the internal structure of the intercom is not changed, so it is not described.

[0021] In order to prevent rain from falling into the shell and the sealing pad 106 from the gap between the button 105 and the button slot 104, the seepage prevention device comprises: a first sealing ring block 107 arranged on the intercom shell 101 at the side of the button slot 104, a second sealing ring block 108 arranged on the button 105 and resisting the first sealing ring block 107, and the second sealing ring block 108 and the button 105 are further provided with a avoiding device.

[0022] In order to reduce the pressure required for deformation, the avoiding device comprises: an avoiding slot 109 opened on the button 105 corresponding to the second sealing ring block 108, the button 105 is an elastic button 105, and the second sealing ring block 108 is fixedly connected with the button 105.

[0023] In order to reduce the contact area with the first sealing ring block 107 when pressing and rebounding, and reduce the friction force, the upper and lower sides of the second sealing ring block 108 are provided with a round corner 110.
