Two way radio device

Abstract

The invention discloses an intercom device. The device comprises: a casing, a main body of the intercom, and an antenna. The casing is provided with an antenna hole, and a hose and a fixed ball are fixed in the antenna hole. The lower end of the antenna is connected with a Connector, the connector is connected to the main body of the walkie-talkie through wires, the connector is located in the hose, the front of the shell is provided with a front cover, and the front cover includes sequentially connected from top to bottom: a sliding cover layer, an intermediate layer , a protective layer, the middle layer is provided with N button holes, and the back of the housing is provided with a fixing hole and a fixing structure, and the fixing structure includes: a spring column, a fixing plate, a ring, and a connecting column, realizing the equipment design It is reasonable, the keys are not easy to be damaged, the waterproof effect of the body is good, the antenna can be pulled out and retracted flexibly, the use method is rich, and the technical effect is convenient for users to use.

Description

technical field [0001] The invention relates to the field of communication equipment research, in particular to an intercom equipment. Background technique [0002] The English name of the walkie-talkie is two way radio. It is a two-way mobile communication tool. It can make calls without any network support, and there is no call charge. It is suitable for relatively fixed and frequent calls. There are currently three types of walkie-talkies: analog walkie-talkies, digital walkie-talkies, and IP walkie-talkies. [0003] The walkie-talkie is the main equipment for simple communication at present, which is convenient for users to communicate in a certain area, and can meet the needs of individual users or groups. [0004] However, in the prior art, the existing walkie-talkie has an antenna that cannot be retracted effectively, resulting in a larger space for temporary use when the antenna is not used, which is not conducive to portability, and the design of the walkie-talkie ...

AI Technical Summary

Problems solved by technology

[0007] The invention provides an intercom device, which solves the problems of unreasonable shell design, easy damage to the keys, easy water ingress in the body, inability to flexibly pull out and retract the antenna, single use mode, and inconvenient use of the existing intercom. Technical issues, achieved the technical effect that the equipment is reasonably designed, the keys are not easy to be damaged, the body is waterproof, the antenna can be pulled out and retracted flexibly, the use methods are rich, and the user is easy to use.
