The non-slip mat may be the same size as the bottom surface of the base unit body 1.
Referring to fig. 2, there is shown a front cross-sectional view of a fixed-line telephone of the present invention. In this embodiment, the detection device 2 includes a measurement ammeter 21 and a restorer 22, the measurement ammeter 21 is connected to restorer 22 one end, the other end of restorer 22 with the side or the side of the base unit body 1 are connected, the both ends of measurement ammeter 21 are equipped with the gauge rod 23, the side of base unit body 1 is equipped with the removal hole, the gauge rod 23 passes the removal hole gets into the inside of base unit body 1.

Referring to fig. 1 to 2, when a user presses the entire measuring meter, the probe pin 23 may enter the base unit 1 from the moving hole and touch the key line 14 inside the base unit 23, so that the resistance of the key line may be measured. For example, as shown in fig. 1 or 2, when the user presses the measurement electric meter 21 for measurement, if the measurement electric meter 21 indicates that the resistance value of the current key line is 64 Ω, the key line is in a normal state. If the measurement ammeter 21 displays that the resistance value of the current key circuit is 0 omega, the key circuit is short-circuited and needs to be maintained; if the measurement electric meter 21 indicates that the current resistance value of the key circuit is infinite, the key circuit is open, and maintenance is also required.
A touch screen frame 13 and a key circuit 14 are provided inside the stationary main body 1, and referring to fig. 3, a schematic circuit diagram of the key circuit 14 according to the present invention is shown.
The measurement meter 21 may be configured to measure a resistance value of the key line 14, so as to determine the state of the key line 14 through the resistance value.
In an alternative embodiment, the detecting rod 23 is inclined downward with respect to the central axis in the horizontal direction by an angle α. The angle range of the inclination angle alpha is 5-45 degrees.
Preferably, the angle range of the inclination angle α is 30 °.
In this embodiment, the touch screen 13 is provided with a touch joint 16, and the touch screen 13 is connected to the key circuit 14 through the touch joint 16.
In order to allow the touch tab 16 to touch the key circuit 14, the horizontal movement distance of the probe rod 23 in the moving hole is S, i.e., the horizontal distance that the probe rod can move in the moving hole is S. The distance difference between the touch joint 16 and the key circuit 14 in the horizontal direction is S, and the hole depth of the connecting hole is d, wherein S is greater than S + d.
In a specific implementation, the horizontal movement distance S of the detecting rod 23 in the moving hole is equal to the resettable compression deformation distance of the repositioner 22, for example, if the resettable compression deformation distance of the repositioner 22 is 5mm, the horizontal movement distance S of the detecting rod 23 in the moving hole is equal to 5 mm.
In order to ensure that the touch joint 16 can be in touch connection with the key circuit 14, during the movement of the detection rod 23, the distance that the detection rod 23 pushes the touch net rack 13 to descend is H, the height difference between the touch joint 16 and the key circuit 14 when the touch joint is at rest is H, H is greater than H, and H is less than the horizontal movement distance S tan α of the detection rod 23 in the movement hole.
In order to improve the accuracy and the sensitivity of the detection, a probe is arranged at the connecting end of the touch connector 16 and the key circuit 14, and the touch connector 16 is connected with the key circuit 14 through the probe.
The probe can be electrified, can be made of materials such as a meter pen of a multimeter, and can directly detect the resistance value of a circuit.
Referring to fig. 4-5, a schematic structure diagram of a detecting device of the present invention at rest and a schematic structure diagram of a detecting device of the present invention at detection are respectively shown. When a user pushes or presses the measuring electric meter 21 from the outside of the base unit body 1, the measuring electric meter 21 drives the detecting rod 23 to move in the moving hole and move from the outside of the base unit body 1 to the inside of the base unit body 1 along the moving hole, so that the detecting rod 23 is inserted into the connecting hole, the detecting rod 23 is connected with the touch net rack 13, the touch net rack 13 can move under the pushing of the detecting rod 23, and the touch net rack 13 also moves downwards under the pushing of the detecting rod 23 in the moving process due to the fact that the detecting rod 23 horizontally inclines downwards, and gradually approaches to the key circuit 14. Because the distance that the touch net rack 13 descends under the pushing of the detection rod 23 is H, and H is less than S tan α, that is, in the process of moving the detection rod 23, the user can make the touch net rack 13 descend by the distance H without pressing the measurement electric meter 21 to the limit of the resettable compression deformation of the resetter 22, and because H is greater than H, that is, under the condition that the touch net rack 13 does not need to descend by the distance H, the touch joint 16 can be connected with the key circuit 14 inside the stationary main body 1, so that the measurement electric meter 21 can detect the key circuit 14.
In actual operation, if the measurement electric meter 21 measures the resistance value of the key line 14 to be infinite, it is determined that the key line is open, if the measurement electric meter 21 measures the resistance value of the key line 14 to be 0, it is determined that the key line is short-circuited, and if the measurement electric meter 21 measures the resistance value of the key line 14 to be a certain value, for example, 3 Ω, 5 Ω, 1.5 Ω, or the like, it is determined that the key line is normal.
The embodiment of the invention discloses a fixed telephone, which has a simple structure and is simple and convenient to operate, when a user finds that a key cannot be pressed or the key does not react, the key circuit can be detected by the measuring ammeter by pressing the measuring ammeter, the whole fixed telephone body does not need to be disassembled for detection, the detection efficiency is improved, the fault reason can be quickly detected, and the fixed telephone is convenient for the user to maintain.
