Fixed-line telephone

Abstract

The invention provides a fixed-line telephone, which comprises a fixed-line telephone body and a detection device, and is characterized in that the detection device is arranged on the side edge of thefixed-line telephone body; the detection device comprises a measurement electric meter and a restorer; one end of the restorer is connected with the measurement electric meter; the other end of the restorer is connected with the side edge of the fixed-line telephone body; detection rods are arranged at the two ends of the measurement electric meter; moving holes are formed in the side edge of thefixed-line telephone body; the detection rods penetrate through the moving holes to enter the fixed-line telephone body; a touch net rack is arranged in the fixed-line telephone body; the touch net rack is vertically arranged above the horizontal direction of a key circuit in the fixed-line telephone body; one end of the touch net rack is provided with a telescopic piece; the touch net rack is connected with the fixed-line telephone body through the telescopic piece; the touch net rack is provided with connecting holes; the detection rods are inserted into the connecting holes so as to be connected with the touch net rack; the detection rods incline downwards with the central axis in the horizontal direction as the center. The fixed-line telephone is simple in structure, and when a user finds that the key cannot be pressed or the key does not react, detection can be performed by pressing the measurement electric meter.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a fixed telephone. Background technique [0002] A fixed telephone is referred to as a fixed telephone, commonly known as a landline, and refers to a telephone that is fixed at a certain location and does not move. The fixed line is one of the important means of communication in modern times. The microphone in the phone is used to modulate the current and voltage on the telephone line through the vibration of the sound, that is, the sound is converted into a voltage signal and transmitted to the other end of the phone through the telephone line, and then used to send the phone. Converter converts voltage signal to sound signal. [0003] When using a fixed line, the user needs to dial a number in the button, and communicate with other telephones by dialing the number. However, with the passage of time, the key lines or printed circuits in the fixed-line phone wil...

AI Technical Summary

Problems solved by technology

[0004] However, the commonly used method needs to disassemble the fixed line every time, and needs to be reassembled after testing. Not only is the operation difficult, but also the detection efficiency is low, and because the fixed line is a sealed precision device, it is easy to damage the circuit due to wrong touch during the detection process. , increases the risk of damage, and is not convenient for users to operate and use
