[0006] By adopting the above technical solution, the data cable is wound around the outer ring of the winding block, and the earphone is locked by the bottom cover and placed inside it, so that it can be carried together with the walkie-talkie in a protected state. When used in a noisy environment, the bottom cover can be removed and the data cable can be wound down, and the sound can be listened to with the earphone, thereby achieving the purpose of normal use in a noisy environment.

[0007] Optionally, a connecting ring is connected to the upper side of the intercom, and the connecting ring is connected to the housing of the intercom as a whole.

[0008] By adopting the above technical solution, a lanyard can be connected to the connecting ring, making it convenient to carry the walkie-talkie.

[0009] Optionally, a through hole is provided in the middle of the bottom of the bottom cover, and the hand-tightening bolt passes through the bottom cover through the through hole.

[0010] Optionally, a ring piece is fixed around the outer ring of the hand-tightening bolt inside the bottom cover, and the diameter of the ring piece is larger than the inner diameter of the through hole.

[0011] By adopting the above technical solution, the sliding piece cooperates with the nut of the hand-tightening bolt to limit it, thereby preventing the hand-tightening bolt from slipping out of the through hole.

[0012] Optionally, a screw hole adapted for a hand-tightening bolt is provided at the middle position of the bottom of the winding block, and the end of the hand-tightening bolt is screwed into the screw hole at the bottom of the winding block.

[0020] See also Figure 1-2The utility model provides a technical solution: a portable short-range wireless communication device, including a walkie-talkie 1 and a bottom cover 2, a connecting ring 11 is connected to the upper right side of the walkie-talkie 1, and the connecting ring 11 is connected to the outer shell of the walkie-talkie 1 as a whole. A lanyard can be connected through the connecting ring 11, so that the walkie-talkie 1 is convenient to carry and can prevent the walkie-talkie 1 from accidentally falling. The antenna and adjustment knob of the walkie-talkie 1 are placed on the top of the walkie-talkie 1, and the display screen, microphone and speaker are located at the front end of the walkie-talkie 1.

[0021] A winding block 3 is fixed in the middle of the bottom of the intercom 1. A winding groove 31 is opened around the outer circle of the winding block 3. The data cable 4 is wrapped around the outer circle of the winding block 3 through the winding groove 31, so that the data cable 4 is received in the outer circle of the ring groove of the ring block. One end of the data cable 4 passes through the inside of the intercom 1 and is connected to its audio output end, and the other end of the data cable 4 is connected to the earphone 41. When the ring groove is noisy, the data cable 4 can be unwound and the earphone 41 can be put on to play the sound, which is convenient for listening to the voice in a noisy environment.

[0022] The bottom cover 2 is placed in contact with the bottom surface of the intercom 1, and the data cable 4 and the earphone 41 when rolled up are stored inside the bottom cover 2 to achieve protection when not in use. An iron sheet 21 is fixed around the top of the bottom cover 2, and the iron sheet 21 is in contact with the bottom outer ring surface of the intercom 1. A magnet 12 is tightly fixed inside the intercom 1 shell above the iron sheet 21. The magnet 12 will attract the iron sheet 21, so that the bottom cover 2 is attracted and in contact with the lowered bottom surface.

[0023] A through-hole 22 is provided in the middle of the bottom of the bottom cover 2, and a hand-tightening bolt 5 is connected through the through-hole 22 of the bottom cover 2. A ring piece 51 is fixed around the outer ring of the hand-tightening bolt 5 inside the bottom cover 2. The diameter of the ring piece 51 is larger than the inner diameter of the through-hole 22. The ring piece 51 cooperates with the nut of the hand-tightening bolt 5 to prevent the bolt from slipping out of the through-hole 22. A screw hole adapted for the hand-tightening bolt 5 is provided in the middle of the bottom of the winding block 3. When the bottom cover 2 is adsorbed and pressed against the bottom of the intercom 1, the hand-tightening bolt 5 is twisted so that its end is screwed into the screw hole at the bottom of the winding block 3 to lock the bottom cover 2.

[0024] During use, during normal use, voice intercom is directly conducted through the microphone and speaker on the surface of the intercom 1, and the intercom sound is played outward through the speaker. When used in a noisy environment, the hand-tightening bolt 5 can be loosened to release the lock of the bottom cover 2, and then the data cable 4 is removed from the outer circle of the winding groove 31 of the winding block 3, and the earphone 41 is worn on the ear, and the sound is played using the earphone 41 to reduce the impact of the surrounding noisy environment on the listening voice. After use, the data cable 4 is wound around the winding groove 31 of the winding block 3, and the bottom cover 2 is adsorbed on the bottom of the intercom 1 by the iron sheet 21 adsorbing the magnet 12, and then the hand-tightening bolt 5 is turned so that its end is screwed into the screw groove reserved in the middle position of the winding block 3, and the data cable 4 and the earphone 41 are stored inside the bottom cover 2. In order to facilitate the carrying of the intercom 1, a lanyard can also be connected through the connecting ring 11 to facilitate the carrying of the intercom 1.
