Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 5 As shown, this utility model provides a wireless intercom communication device for tunnels, including a walkie-talkie 1. The walkie-talkie 1 has an installation hole 2 inside, and a telescopic rod 3 is fixedly installed inside the installation hole 2. A spring 4 is sleeved on the outside of the telescopic rod 3, and a locking block 5 is fixedly installed on the outside of the spring 4. A connecting sleeve 6 is sleeved on the outside of the walkie-talkie 1, and a locking hole 7 is opened inside the connecting sleeve 6. The locking hole 7 and the locking block 5 are locked together.

[0021] When working normally, first put the connecting sleeve 6 onto the outside of the walkie-talkie 1. Then press the locking block 5 towards the middle of the walkie-talkie 1, so that the inner wall of the connecting sleeve 6 squeezes and slides the locking block 5. At the same time, when the connecting sleeve 6 moves upward to fit the locking hole 7 and engage with the locking block 5, the locking block 5 will drive the telescopic rod 3 forward through the elastic force of the spring 4, so that the locking block 5 engages with the locking hole 7, thereby fixing the walkie-talkie 1 and the connecting sleeve 6. This makes it less likely for the walkie-talkie 1 to fall off and be damaged when working at high speed.

[0022] The walkie-talkie 1 has a mounting base 8 at the rear, and a sliding groove 9 is provided inside the mounting base 8. A slider 10 is slidably connected inside the sliding groove 9. The slider 10 is fixedly connected to the connecting sleeve 6. A buckle 11 is fixedly installed at the rear of the mounting base 8.

[0023] First, fasten the buckle 11 to the pocket of the garment to fix the mounting base 8. Then, install the connecting sleeve 6 by sliding it through the slider 10 and the slide groove 9. This allows the connecting sleeve 6 to fix the walkie-talkie 1, thus facilitating installation.

[0024] The walkie-talkie 1 has a speaker 12 fixedly installed inside, buttons 13 on both the left and right ends, and a signal enhancement antenna 14 and a control knob 15 fixedly installed on the top of the walkie-talkie 1.

[0025] The main function of the speaker 12 is to facilitate sound transmission. When the button 13 is pressed, sound is transmitted through the speaker 12 for conversation, while maintaining a sufficient volume to ensure that the sound is heard clearly.

[0026] The walkie-talkie 1 has a silicone sleeve 16 on its outer side, and the silicone sleeve 16 has an installation groove 17 inside, which is engaged with the button 13.

[0027] The mounting slot 17 engages with the button 13, which secures the silicone sleeve 16 to the outside of the walkie-talkie 1, thus providing protection for the walkie-talkie 1.

[0028] Among them, a connecting strip 18 is fixedly installed in front of the silicone sleeve 16, and a dustproof hole 19 is opened inside the connecting strip 18. The dustproof hole 19 is located in front of the speaker 12. A silicone pad 20 is fixedly installed inside the connecting sleeve 6. The silicone pad 20 is located on the upper side of the walkie-talkie 1.

[0029] During operation, a significant amount of dust is generated. Since the walkie-talkie 1 is located on the outside, dust can easily accumulate on its surface, causing the speaker 12 to become blocked. In this case, the dustproof hole 19 is located in front of the speaker 12 to shield it. Without obstructing the sound transmission of the speaker 12, it can effectively shield the speaker 12, thus preventing the speaker 12 from becoming blocked and the sound from not being able to travel. At the same time, since a silicone pad 20 is provided on the upper side of the walkie-talkie 1, when the walkie-talkie 1 is dropped, the silicone pad 20, together with the silicone sleeve 16, can achieve a shock absorption effect on the walkie-talkie 1, thereby reducing the possibility of the walkie-talkie 1 being damaged by a fall.

[0030] There are two slides 9 and two sliders 10. The two slides 9 and the two sliders 10 are located behind the walkie-talkie 1. The two sliders 10 are fixedly installed with the connecting sleeve 6.

[0031] The two sliders 10 are fixedly connected to the connecting sleeve 6 and slidably connected to the two sliding grooves 9, so that the connecting sleeve 6 can be quickly fixed and the mounting base 8 can drive the connecting sleeve 6 to be installed in front of the chest. When it is necessary to make a conversation, you can press the button 13 to make a conversation without having to hold it all the time, thus improving the efficiency of communication at work.

[0032] Working principle and usage process of this utility model:

[0033] Firstly, a sliding groove 9 is provided inside the mounting base 8, and a slider 10 is slidably connected inside the sliding groove 9. At the same time, the slider 10 is fixedly connected to the connecting sleeve 6, and a buckle 11 is fixedly installed at the rear of the mounting base 8. The buckle 11 is fastened to the pocket of the clothes to fix the mounting base 8. Then, the connecting sleeve 6 is installed by sliding the slider 10 to the sliding groove 9, so that the connecting sleeve 6 drives the walkie-talkie 1 to be fixed, thereby achieving the effect of making the walkie-talkie 1 easy to install.

[0034] Secondly, because a telescopic rod 3 is fixedly installed inside the mounting hole 2, a spring 4 is sleeved on the outside of the telescopic rod 3, and a locking block 5 is fixedly installed on the outside of the spring 4, and a connecting sleeve 6 is sleeved on the outside of the walkie-talkie 1, and a locking hole 7 is opened inside the connecting sleeve 6, and the locking hole 7 is engaged with the locking block 5, when working normally, first the connecting sleeve 6 is put on the outside of the walkie-talkie 1, and then the locking block 5 is pressed towards the middle of the walkie-talkie 1, so that the inner wall of the connecting sleeve 6 squeezes and slides the locking block 5. At the same time, when the connecting sleeve 6 moves upward to engage the locking hole 7 with the locking block 5, the locking block 5 will drive the telescopic rod 3 forward through the elastic force of the spring 4, so that the locking block 5 is engaged with the locking hole 7, thereby fixing the walkie-talkie 1 and the connecting sleeve 6, so that the walkie-talkie 1 is not easy to fall off and be damaged when working at a large scale;

[0035] Finally, a connecting strip 18 is fixedly installed in front of the silicone sleeve 16. A dustproof hole 19 is provided inside the connecting strip 18 and is located in front of the speaker 12. A silicone pad 20 is fixedly installed inside the connecting sleeve 6 and is located on the upper side of the walkie-talkie 1. When working, a lot of dust will be generated. Since the walkie-talkie 1 is located on the outside, dust can easily accumulate on the surface of the walkie-talkie 1, causing the speaker 12 to become blocked. At this time, the dustproof hole 19 is located in front of the speaker 12 to block the speaker 12. Without obstructing the sound transmission of the speaker 12, it can effectively block the speaker 12, thereby effectively preventing the speaker 12 from being blocked and the sound from not being able to propagate.
