[0028] Example
[0029] like Figure 1-2As shown, the utility model proposes a police concealed communication terminal, including a mounting block 2 and a headset 3, and also includes a pendant 1, which can be an ordinary necklace or earring and other products. The pendant 1 is fixedly mounted on both sides of the mounting block 2, and a Bluetooth signal receiver 4 is fixedly mounted on the headset 3. A Bluetooth signal transmitter 7 is fixedly mounted on the mounting block 2, and the Bluetooth signal transmitter 7 transmits the signal to the Bluetooth signal receiver 4. A wire interface 6 is provided on the mounting block 2 for connecting a wired headset, and a limiting mechanism for adjusting the length of the pendant 1 is provided on the mounting block 2.
[0030] like Figure 2-4 As shown, in this embodiment, the concealed communication terminal also includes a limiting mechanism, which includes a limiting block 14 slidably mounted on the mounting block 2, the bottom of the limiting block 14 is a section setting, a limiting plate 12 is slidably mounted in the mounting block 2, and a plurality of limiting holes 13 arranged at equal distances are opened on the limiting plate 12, one end of the limiting plate 12 is fixedly connected to one end of the pendant 1, and one end of the limiting block 14 is located in the limiting hole 13. When the length of the pendant 1 needs to be adjusted, a pull plate 9 is fixedly mounted on one end of the limiting block 14, and the pull plate 9 is provided with anti-slip grooves. A spring 11 is fixedly mounted on one side of the mounting block 2, and one end of the spring 11 is fixedly connected to the pull plate 9. Pull the pull plate 9 upwards and insert the limit block 14 into the mounting block 2. Since the bottom of the limit block 14 is a cross-section setting, the limit plate 12 moves inward, and one end of the limit plate 12 squeezes the cross-section of the limit block 14, causing the limit block 14 to move upward. As the limit plate 12 moves, the limit block 14 is able to be in the limit hole 13 under the action of the spring 11, thereby fixing the limit plate 12. If the length of the pendant 1 needs to be shortened, only the limit plate 12 needs to be pushed inwards. When the limit plate 12 needs to be removed, pull the limit block 14 upwards and pull it out of the limit hole 13. At this time, the limit plate 12 can be pulled out, and the pendant 1 can be removed from the neck.
[0031] like Figure 1-3 As shown, a microphone 8 is fixedly installed on the mounting block 2, which is located near the mouth and can transmit sound clearly. An audio transmitter and an audio receiver are provided in the microphone 8. The audio transmitter is used to transmit sound, and the audio receiver is used to receive external audio. The received audio is then transmitted to the Bluetooth signal receiver 4 by the Bluetooth signal transmitter 7 for listening. A dustproof cloth is provided on the microphone 8, so that the staff can input audio by simply lowering their heads slightly. A slot 10 is provided on one side of the mounting block 2, and a limiting plate 12 is slidably connected to the slot 10. An earplug 5 is fixedly installed on one side of the headset 3, and the earplug 5 is arranged in an arc shape.
[0032] The working principle of this embodiment is as follows: when the length of the ornament 1 needs to be adjusted, a pull plate 9 is fixedly installed on one end of the limit block 14, and an anti-slip pattern is set on the pull plate 9. A spring 11 is fixedly installed on one side of the mounting block 2, and one end of the spring 11 is fixedly connected to the pull plate 9. The pull plate 9 is pulled upward to insert the limit block 14 into the mounting block 2. Since the bottom of the limit block 14 is a cross-section setting, the limit plate 12 moves inward, and one end of the limit plate 12 squeezes the cross-section of the limit block 14, causing the limit block 14 to move upward. As the limiting plate 12 moves, the limiting block 14 is able to be placed in the limiting hole 13 under the action of the spring 11, thereby fixing the limiting plate 12. If the length of the pendant 1 needs to be shortened, it is only necessary to push the limiting plate 12 inward. When the limiting plate 12 needs to be removed, the limiting block 14 is pulled upward to remove it from the limiting hole 13. At this time, the limiting plate 12 can be pulled out and the pendant 1 can be removed from the neck, thereby concealing the use process of the device, facilitating communication, flexibly adjusting the length of the pendant, improving wearing comfort, and making it convenient to wear.
[0033] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
