Interphone with long rod

Abstract

The invention discloses an interphone with a long rod. A flexible rod is arranged on a rear cover of the interphone. The flexible rod is composed of a plurality of sub-rods which are made of round pipes and are mutually nested. The sub-rod at the outermost layer is embedded in a strip-shaped groove of the rear cover of the interphone. A pull ring is fixed at the tail end of the sub-rod located at the innermost layer. The pull ring is located out of the groove. A transition pipe of the pull ring is in threaded sleeve joint with the tail end of the sub-rod at the innermost layer. Grooves parallel to the groove of the rear cover are arranged at two sides of the groove of the rear cover. A first flexible pipe and a second flexible pipe are respectively placed in the two grooves. The two flexible pipes are detachably fixed in the grooves through bandages stretching across the grooves. The top end of the sub-pipe at the outermost layer of the first flexible pipe can be inserted into the tail end of the sub-rod at the innermost layer of the flexible rod and is in threaded sleeve joint with the tail end of the sub-rod. The tail end of the sub-pipe at the innermost layer of the first flexible pipe can be inserted into the top end of the sub-pipe at the outermost layer of the second flexible pipe and is in threaded sleeve joint with the top end of the sub-pipe. According to the interphone, signals in a very large range can be captured, and the interphone is very convenient for carriage and use.

Description

technical field [0001] The invention belongs to the technical field of walkie-talkies, in particular to a walkie-talkie whose length can be adjusted. Background technique [0002] The walkie-talkie is a short-range wireless communication device commonly used in daily production and life. In the use of the walkie-talkie, it is often encountered that the signal of the walkie-talkie is not good. It is necessary to raise the walkie-talkie to capture the signal, or extend the walkie-talkie out of the building, such as out of the window When capturing signals in a slightly open environment, especially in the wild or in potholes, it is even more necessary to lift or extend the walkie-talkie to a certain position to capture a good signal and have a loud conversation. However, the current walkie-talkie can only rely on the extension of the human arm to adjust the position of the walkie-talkie to capture the signal, which is not only inconvenient to use, but also has a very limited ra...
