[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figures 1 to 4In an embodiment of the utility model, a foldable communication terminal includes a walkie-talkie body 1, one end of the walkie-talkie body 1 is rotatably installed with a signal column 2 through a rotating signal transmission mechanism, the rotating signal transmission mechanism includes a fixed ring 3 and a rotating column 4, the fixed ring 3 is fixedly installed on the back end of the walkie-talkie body 1, the inner wall of the fixed ring 3 is rotatably connected with the rotating column 4, the rotating column 4 is fixedly connected to the signal column 2, and the inner wall of the fixed ring 3 and the inner wall of the rotating column 4 are installed with a damping mechanism, the damping mechanism is used to increase the friction between the fixed ring 3 and the rotating column 4, so that the signal column 2 remains in the current position.

[0019] In this embodiment, at a site of use (e.g., a water conservancy construction site), a walkie-talkie is generally used for real-time communication. When the walkie-talkie is in use, the signal post 2 is rotated from the bottom to an upward vertical position. When the walkie-talkie is not in use, in order to prevent the signal post 2 from being bent and damaged by force, the signal post 2 in the upward vertical position is rotated downward from the highest point to complete the folding and storage of the signal post 2.

[0020] After the rotating column 4 has completed its rotation, the damping mechanism can effectively increase the friction between the fixed ring 3 and the rotating column 4, so that the signal column 2 remains in its position after rotation, thereby avoiding the problem of the signal column 2 rotating on its own due to low friction when not rotated manually.

[0021] Please refer to Figure 1 The rotation signal transmission mechanism also includes an upper conductive ring 10 and a lower conductive ring 12 fixedly installed inside the fixed ring 3. The upper conductive ring 10 and the lower conductive ring 12 are annular structures. The outer wall of the rotating column 4 is fixedly connected to the upper rotating guide column 9 and the lower rotating guide column 11. The conductive portion at the end of the upper rotating guide column 9 and the conductive portion at the end of the lower rotating guide column 11 are in contact with the inner periphery of the upper conductive ring 10 and the lower conductive ring 12 respectively. The input end of the conductive portion of the upper rotating guide column 9 is connected to the No. 1 input signal wire 5 connected to the signal column 2. The output end of the upper conductive ring 10 is connected to the input end of the circuit board inside the intercom body 1 through the No. 2 input signal wire 7. The input end of the lower conductive ring 12 is connected to the output end of the circuit board inside the intercom body 1 through the No. 1 output signal wire 8. The output end of the conductive portion of the lower rotating guide column 11 is connected to the No. 2 output signal wire 6 connected to the signal column 2.

[0022] In this embodiment, the receiving antenna in the signal post 2 receives the signal and transmits it to the upper rotating guide post 9 via the first input signal wire 5. The upper rotating guide post 9 then transmits the signal through the upper conductive ring 10 and the second input signal wire 7 to the circuit board inside the intercom body 1. After being decoded and amplified by the circuit board, the signal is played out through the speaker.

[0023] When using the device to communicate with other staff, the microphone receives sound and converts the sound signal into an electrical signal and transmits it to the internal circuit board of the intercom body 1. After that, it is encoded and transmitted to the lower rotating guide column 11 through the No. 1 output signal wire 8 and the lower conductive ring 12. The signal then enters the transmitting antenna in the signal column 2 through the No. 2 output signal wire 6 and is emitted.

[0024] Please refer to Figure 4 The damping mechanism includes a plurality of grooves 13 clamped inside the fixed ring 3, and the inner wall of the groove 13 is axially slidably connected with a slide 15, and a spring 14 is connected between one end of the inner wall of the groove 13 and one end of the slide 15. The other end of the slide 15 is fixedly installed with a plug-in column 16 that penetrates the inner cavity of the fixed ring 3. The end of the plug-in column 16 away from the slide 15 is a hemispherical structure, and the outer periphery of the rotating column 4 is provided with a plug-in groove 17 that matches the outer wall of the hemispherical part of the plug-in column 16.

[0025] In this embodiment, when the signal column 2 rotates, the signal column 2 drives the rotating column 4 to rotate in the fixed ring 3. When the rotating column 4 rotates, the rotating column 4 drives the plug-in slot 17 to rotate. The rotating plug-in slot 17 is squeezed against the outer wall of the hemispherical end of the plug-in column 16. The compressed plug-in column 16 pushes the slide plate 15 to slide in the groove body 13 and compresses the spring 14.

[0026] During the rotation of the rotating column 4, the multiple plug-in slots 17 are continuously overlapped, squeezed, and misaligned with the multiple plug-in posts 16 in the above-mentioned manner until the rotating column 4 completes the rotation along with the signal column 2. At this time, the multiple plug-in slots 17 are aligned one by one with the multiple plug-in posts 16. At this time, the plug-in slots 17 are plugged into the plug-in posts 16, thereby increasing the friction between the rotating column 4 and the fixed ring 3, and keeping the signal column 2 in its current position.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
