Description
Technical Field
The utility model relates to the technical field of interphones, in particular to a digital interphone with a frequency modulation knob capable of self-locking.
Background
The interphone is used as a bidirectional mobile communication tool, can communicate without any network support, and has no telephone charge, thus being widely applicable to construction and engineering installation occasions with relatively fixed and frequent communication.
The Chinese patent with application number 201320001532.8 is combined, and the digital interphone is disclosed. Referring to fig. 1, the digital interphone comprises a body 1, an antenna 2 and a frequency modulation knob 3, wherein a frequency scale 5 is arranged on the upper surface of the frequency modulation knob 3, a pointer 4 for reading the frequency scale 5 is arranged on the body 1, and the pointer 4 is positioned at the periphery of the frequency modulation knob 3. Next to the fm knob 3 is a volume/switch adjustment knob 6, by means of which the volume of the intercom can be adjusted. In the use process, the interphone can be determined to work at the frequency by only rotating the frequency modulation knob to align the corresponding frequency scale with the pointer. In addition, an indication line is arranged on the frequency modulation knob 3, a frequency scale ring is arranged on the periphery of the frequency modulation knob, and when the frequency modulation knob is used, the indication line can be modulated in place by rotating the frequency modulation knob until a certain frequency scale is aligned. When the digital interphone is a fixed frequency band machine, the digital interphone is generally provided with 1-16 frequency bands, and the frequency modulation knob corresponds to 16 gears. The machine can be used for talking by only adjusting the interphone to the same gear, such as 1 to 1,2 to 2 and the like.

If the frequency modulation knob lacks a self-locking structure, a user can easily rotate the knob due to misoperation in the use process, so that the conversation frequency is replaced by mistake. For example, because the interphone body is small, the frequency modulation knob is arranged at the top of the body, and the frequency scale of the interphone body is smaller no matter the interphone body is arranged around the frequency modulation knob or at the top of the frequency modulation knob, so that whether the interphone body is in place or not can not be known quickly in places with dark light, and the interphone body is difficult to identify for engineering personnel with poor eyesight. The frequency modulation knob is refitted from the top of the machine body to the front or back of the machine body, and does not meet the design standard.

The end of the locking bar 310 is not always moved out of the blind hole 221.
In the above scheme, the digital interphone provided by the utility model is provided with the self-locking mechanism 300 for the frequency modulation knob 200 and the light-emitting body 322 combined with the self-locking mechanism 300, so that a user does not need to worry about misoperation after the frequency is modulated, and the light-emitting body 322 is utilized to lighten the number of the gear in place, so that the user can quickly know whether the user can modulate the frequency in place or not in places with darker light, and the advantage is particularly outstanding for engineering personnel with poor eyesight.
Specifically, the self-locking mechanism 300 is composed of a retractable locking rod 310 extending from a transmission shaft 220 of the frequency modulation knob 200 and a locking ring 320 sleeved on the periphery of the frequency modulation knob 200, wherein a gear slot 321 is formed in each gear of 16 gears on the locking ring 320, and an annular slot 324 is formed in which the free end of the locking rod 310 is abutted. When the locking lever 310 slides in the annular groove 324 and is not pushed into a certain gear groove 321 by the spring 311 in the rotating process of the frequency modulation knob 200, the frequency modulation is not in place; the tuning is shown in place when the lock lever 310 is pushed into a certain gear slot 321 by the annular slot 324 under the action of the spring 311 during rotation of the tuning knob 200. For example, the locking lever 310 is pushed into the number 1 gear slot 321, which represents that the current frequency band of the interphone is number 1, and the opposite side can ensure the call only by adjusting to the number 1 frequency band. Since the locking rod 310 extends out from the transmission shaft 220 of the fm knob 200, when the locking rod 310 slides from the annular groove 324 to the gear groove 321, the locking rod is limited left and right, thereby effectively avoiding the occurrence of false rotation of the fm knob 200 in place.

The light emitting body 322 is stuck with a digital label representing the frequency range, so that the current frequency modulation range can be known quickly as long as the light emitting body 322 is lighted. The smart utility model uses the locking bar 310 to mount the second conductive plate 323, and connects the second conductive plate 323 to the power supply of the interphone circuit board through the conductive wire 313, so that the locking bar 310 can light the illuminant 322 representing which frequency band through the contact of the two conductive plates only by pushing into which gear slot 321 under the action of the spring 311. It is seen from this that the present utility model also skillfully achieves the user to quickly know the currently tuned frequency band on the basis of completing the self-locking of the fm knob 200. As for the illuminant 322, an LED lamp bead with high light-emitting brightness is preferentially selected, the cathode of the LED lamp bead is grounded, and the anode is arranged in the gear slot 321 in the form of a conductive sheet.
